ANTISENSE COMPOSITIONS TARGETED TO beta 1 ADRENOCEPTOR-SPECIFIC MRNA AND METHODS OF USE

Abstract: Disclosed are antisense oligonucleotide, polynucleotide, and peptide nucleic acid compounds that specifically bind to mammalian mRNA encoding a beta 1-adrenoceptor polypeptide and that are useful in the control and/or treatment of cardiac dysfunction, hypertension, hypertrophy, myocardial ischemia, and other cardiovascular diseases in an affected mammal, and preferably, in a human subject. The antisense compounds disclosed herein, and pharmaceutical formulations thereof, provide sustained control of beta 1-adrenoceptor expression over prolonged periods, and achieve therapeutic effects from as little as a single dose. Administration of these antisense compositions to approved animal models resulted in a decrease in blood pressure, but no significant change in heart rate. Use of such antisense compositions in the reduction of beta 1-adrenoceptor polypeptides in a host cell expressing beta 1-adrenoceptor-specific mRNA, and in the operation of medicaments for treating human and animal diseases, and in particular, hypertension and other cardiac dysfunction is also disclosed.

Description: DESCRIPTION ANTISENSE COMPOSITIONS TARGETED TO MRNA AND METHODS OF USE In a first embodiment, the invention provides antisense oligonucleotides that specifically bind to a mammalian β j -AR-specific gene or a mammalian β j -AR-specific mRNA in a host cell, and alter the expression of, or quantity of, β,-AR polypeptide produced in the cell. In a second embodiment, the invention provides antisense peptide nucleic acids that specifically bind to a mammalian β r AR-specific gene or a mammalian β r AR-specific mRNA in a host cell, and alter the expression of, or quantity of, β r AR polypeptide produced in the cell. In a third embodiment, the invention provides antisense polynucleotides that specifically bind to a mammalian βj-AR-specific gene or to a mammalian β r AR-specific mRNA in a host cell, and alter the expression of, or quantity of, βrAR polypeptide produced in the cell.

The oligonucleotide or PNA compound may also consist of the sequence of SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:l l, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, SEQ ID NO:26, SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, SEQ ID NO:31, SEQ ID NO:32, SEQ ID NO:33, SEQ ID NO:34, SEQ ID NO:35, SEQ ID NO:36, SEQ ID NO:37, SEQ ID NO:38, SEQ ID NO:39, SEQ ID NO:40, SEQ ID NO:41, SEQ ID NO:42, SEQ ID NO:43, SEQ ID NO:44, SEQ ID NO:45, SEQ ID NO:46, SEQ ID NO:47, SEQ ID NO:48, SEQ ID NO:49, SEQ ID NO:50, SEQ ID NO:51, SEQ ID NO:52, or SEQ ID NO:53, or any one or more of the smaller n-mer sequences illustrated in SEQ ID NO: 54 through SEQ ID NO: 186. As described above, the length of the preferred oligonucleotide or PNA compounds preferably will be on the order of from about nine to about 35 or so nucleotides. As such, in addition to those compounds that are nine nucleotides in length, and those compounds that are 35 nucleotides in length, all intermediate size compounds are also contemplated to be useful in the practice of the present invention. Thus, oligonucleotide or PNA compounds that are ten nucleotides in length, eleven nucleotides in length, twelve nucleotides in length, thirteen nucleotides in length, fourteen nucleotides in length, fifteen nucleotides in length, sixteen nucleotides in length, seventeen nucleotides in length, eighteen nucleotides in length, nineteen nucleotides in length, twenty nucleotides in length, twenty-one nucleotides in length, twenty-two nucleotides in length, twenty-three nucleotides in length, twenty-four nucleotides in length, twenty-five nucleotides in length, twenty-six nucleotides in length, twenty-seven nucleotides in length, twenty eight nucleotides in length, twenty-nine nucleotides in length, thirty nucleotides in length, thirty-one nucleotides in length, thirty-two nucleotides in length, thirty-three nucleotides in length, and thirty-four nucleotides in length are also contemplated to fall within the scope of the present disclosure. In fact, the preferred oligonucleotide or PNA compounds may also be slightly shorter than the preferred range, that is, they may be about six or about seven or about eight nucleotides in length, or they may even be slightly longer than the preferred range (i.e., they may be about thirty-six or about thirty-seven or even about thirty-eight or so nucleotides in length), and may still function to reduce the level of β r AR polypeptide in a cell, and thus, effective in the treatment of cardiac disorders resulting from an elevated level of β r AR polypeptide. Likewise, there is no obligate requirement that the antisense compounds be exactly 100% complementary to a given target sequence on the mammalian β,-AR mRNA. Nor is there an obligate requirement that the antisense compounds be exactly 100% identical to one of the sequences disclosed in SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:l l, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, SEQ ID NO:26, SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, SEQ ID NO:31, SEQ ID NO:32, SEQ ID NO:33, SEQ ID NO:34, SEQ ID NO:35, SEQ ID NO:36, SEQ ID NO:37, SEQ ID NO:38, SEQ ID NO:39, SEQ ID NO:40, SEQ ID NO:41, SEQ ID NO:42, SEQ ID NO:43, SEQ ID NO:44, SEQ ID NO:45, SEQ ID NO:46, SEQ ID NO:47, SEQ ID NO:48, SEQ ID NO:49, SEQ ID NO:50, SEQ ID NO:51, SEQ ID NO: 52, or SEQ ID NO: 53, or any one or more of the smaller rø-mer sequences illustrated in SEQ ID NO:54 through SEQ ID NO: 186. In fact, the only requirement is that the oligonucleotide or PNA compound have sufficient homology to the gene or the mRNA encoding βrAR polypeptide so that upon specifically binding to the complementary region, a reduction in either the transcription of the β^AR gene and/or a reduction in the translation of βi-AR polypeptide from the mRNA is observed. Therefore, the compounds may have 4 or fewer, 3 or fewer, 2 or fewer, or even 1 mismatch from the target sequence to which it specifically binds, and may still be sufficiently active to cause a reduction in β r AR polypeptide within the host cell. Thus, in addition to those compounds disclosed above that comprise sequences that are 100% identical to the sequences disclosed in SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO: 10, SEQ ID NO:l l, SEQ ID NO: 12, SEQ ID NO: 13, SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, SEQ ID NO:26, SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, SEQ ID NO:31, SEQ ID NO:32, SEQ ID NO:33, SEQ ID NO:34, SEQ ID NO:35, SEQ ID NO:36, SEQ ID NO:37, SEQ ID NO:38, SEQ ID NO:39, SEQ ID NO:40, SEQ ID NO:41, SEQ ID NO:42, SEQ ID NO:43, SEQ ID NO:44, SEQ ID NO:45, SEQ ID NO:46, SEQ ID NO:47, SEQ ID NO:48, SEQ ID NO:49, SEQ ID NO:50, SEQ ID NO:51, SEQ ID NO:52, or SEQ ID NO:53, or any one or more of the smaller n-mer sequences illustrated in SEQ ID NO:54 through SEQ ID NO: 186, the invention also encompasses antisense compounds that comprise sequence regions that are about 99%, about 98%, about 97%, about 96%, about 95%, about 94%, about 93%, about 92%, about 91%, or even about 90% identical to a portion of one of those sequences, so long as the resulting degenerate nucleotide sequence retains sufficient homology so that it specifically binds to the gene or mRNA encoding β AR polypeptide. 2.2 POLYNUCLEOTIDE AND POLY-PNA COMPOUNDS In certain embodiments, the polynucleotide comprises at least 9 contiguous bases from SEQ ID NO:4, SEQ ID NO:5, SEQ ID NO:6, SEQ ID NO:7, SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO:10, SEQ ID NO:l l, SEQ ID NO:12, SEQ ID NO:13, SEQ ID NO:14, SEQ ID NO:15, SEQ ID NO:16, SEQ ID NO:17, SEQ ID NO:18, SEQ ID NO:19, SEQ ID NO:20, SEQ ID NO:21, SEQ ID NO:22, SEQ ID NO:23, SEQ ID NO:24, SEQ ID NO:25, SEQ ID NO:26, SEQ ID NO:27, SEQ ID NO:28, SEQ ID NO:29, SEQ ID NO:30, SEQ ID NO:31, SEQ ID NO:32, SEQ ID NO:33, SEQ ID NO:34, SEQ ID NO:35, SEQ ID NO:36, SEQ ID NO:37, SEQ ID NO:38, SEQ ID NO:39, SEQ ID NO:40, SEQ ID NO:41, SEQ ID NO:42, SEQ ID NO:43, SEQ ID NO:44, SEQ ID NO:45, SEQ ID NO:46, SEQ ID NO:47, SEQ ID NO:48, SEQ ID NO:49, SEQ ID NO:50, SEQ ID NO:51, SEQ ID NO:52, or SEQ ID NO:53. In other aspects of the invention, the polynucleotide comprises DNA, RNA, PNA, or preferably a derivatized or modified polynucleotide, including phosphorothioate derivates and the like. Preferably the antisense polynucleotide compound comprises a sequence that is substantially the full-length complement of the β r AR mRNA, wherein binding of the substantially full-length complementary sequence to the βj-AR mRNA is effective in reducing the translation of the mRNA into the β r AR polypeptide. Preferably the substantially full-length complementary sequence is comprised within a suitable vector that may be delivered to appropriate host cells. The vector preferably comprises a nucleic acid segment that is operably linked to a promoter sequence that expresses the complementary antisense sequence in the host cell. This complementary near full-length sequence is then able to specifically bind to the substantially full length β r AR mRNA and thereby prevent or substantially reduce the translation of the mRNA into βrAR polypeptide. The term substantially full-length is meant to include those sequences that comprise a sequence that is complementary to a region that is at least about 80% or more of the native β^AR-specific mRNA. Thus, for a β r AR mRNA that is 1000 nucleotides in length, a suitable complementary substantially full-length complement is a sequence that is complementary to a region of at least 800 nucleotides of the particular βj-AR mRNA. Likewise, all sequences that are greater than 80% of the full-length sequences (i.e. those that are at least 81% full length, at least 82% full length, at least 83% full length, at least 84% full length, at least 85% full length, at least 86% full length, at least 87% full length, at least 88% full length, at least 89% full length, at least 90% full length, at least 91% full length, at least 92% full length, at 5 least 93% full length, at least 94% full length, at least 95% full length, at least 96% full length, at least 97% full length, at least 98% full length, and at least 99% full length are also contemplated to fall within the scope of the present disclosure. 2.3 COMPOSITIONS COMPRISING A βj-AR ANTISENSE COMPOUND AND A SECOND l o CARDIAC THERAPEUTIC AGENT When desirable, the clinician may combine two or more of the oligonucleotide, polynucleotide, or PNA compounds disclosed above to provide an antisense "cocktail" to effect a more substantial reduction in the levels of β r AR polypeptide.

These cocktail therapies may comprise at least two antisense compounds specific for a mammalian β r AR-encoding gene or mRNA, and at least a third antisense compound specific for the same mRNA, or alternatively, an mRNA encoding another polypeptide in the RAS pathway as described above. The third antisense compound may be specific for renin, AT-1 receptor, ACE, or angiotensinogen, or another gene or mRNA involved in biochemical pathways involved in producing or regulating blood pressure and/or causing or contributing to hypertension, ischemia, cardiac hypertrophy, or other cardiac dysfunction in an affected animal. Alternatively, the constructs may even be specific for one or more particular transcription factor(s) that regulate one or more genes involved in producing hypertension, ischemia, cardiac hypertrophy, or other cardiac dysfunction in a mammal. Such combined therapy approached using two or more antisense oligonucleotides are particularly desirable where enhanced or synergistic activity towards treating hypertension ischemia, cardiac hypertrophy, or other cardiac dysfunction is achieved. The invention further provides a method for reducing expression of a gene encoding mammalian β r AR polypeptide in a host cell, the method comprising providing to the host cell an amount of an antisense oligonucleotide, polynucleotide, or peptide nucleic acid that specifically binds to an mRNA encoding the β j -AR polypeptide, effective to reduce the amount of β^AR polypeptide in the cell. Additionally, the invention provides a method for reducing the number of mammalian β^AR polypeptides in a cell, the method comprising introducing into the cell at least a first antisense oligonucleotide, polynucleotide, or peptide nucleic acid that specifically binds to all, substantially-all, or a portion of the mRNA expressed from a gene encoding a mammalian β r adrenoceptor polypeptide, and further wherein binding of the first antisense oligonucleotide, polynucleotide, or peptide nucleic acid to the mRNA is effective in reducing the number of mammalian β,-AR polypeptides in the host cell expressing the mRNA. The mvention also provides a method for decreasing or treating hypertension in an animal, the method comprising administering to the animal an effective amount of at least a first antisense oligonucleotide, polynucleotide, or peptide nucleic acid, wherein the compound specifically binds to all, substantially all, or a portion of the mRNA expressed from a gene encoding a mammalian β r AR polypeptide, and further wherein binding of the compound to the mRNA is effective in decreasing the number of such polypeptides in a host cell expressing the mRNA. The invention additionally provides a method for treating a disease associated with elevated β j -AR activity in a mammal, the method comprising administering to the animal an effective amount of at least a first antisense oligonucleotide, polynucleotide, or peptide nucleic acid compound wherein the compound specifically binds to all, substantially all, or a portion of the mRNA expressed from a gene encoding a mammalian β r AR polypeptide, and further wherein binding of the compound to the mRNA is effective in decreasing the receptor activity or receptor number in a host cell expressing the mRNA, such that a decrease in βi-adrenoceptor activity is effected, thereby resulting in amelioration of the disease that results from, or is exacerbated by, an elevated level of β r AR activity in the affected animal. The invention also provides a method for treating a cardiac hypertrophic or ischemic disease that is associated with, that results from, or is exacerbated by, the presence of, or an elevation in, βi-adrenoceptor polypeptides in the affected animal. This method generally involves the administration to the animal of one or more compositions that comprise at least a first antisense oligonucleotide, polynucleotide, or peptide nucleic acid compound, wherein the compound specifically binds to all, substantially all, or a portion of the mRNA expressed from a gene encoding a mammalian βi-AR polypeptide in an amount, and for a time sufficient to decrease the number, amount, or activity of the βi-adrenoceptor polypeptide in a host cell expressing the mRNA. Further provides are kits for treating hypertension in a human comprising: (a) a pharmaceutically-acceptable formulation comprising t least a first oligonucleotide of at least 9 to about 35 bases in length, wherein the oligonucleotide specifically binds to a portion of mRNA expressed from a gene encoding a mammalian β r AR polypeptide, and further wherein binding of the oligonucleotide to the mRNA is effective in decreasing the activity, amount, or number of receptor polypeptides in a host cell expressing the mRNA; a pharmaceutical excipient; and (b) instructions for using the kit. In addition to methods involving the delivery of exogenous oligonucleotide compositions to a host cell, or administration of such compositions to an animal in a therapeutic pharmaceutical formulation, the present invention also concerns gene therapy methods for introducing into a host cell a DNA construct that is transcribed by the cell machinery to give rise to an antisense RNA molecule that specifically binds to a portion of an mRNA encoding a mammalian β r AR polypeptide. In a preferred embodiment, such therapies may be accomplished through the use of viral vectors, such as retro-, adeno- or adeno-associated viruses as described hereinbelow. Regulation of expression of a gene encoding a mammalian βi-AR polypeptide in a mammalian cell genomes may also be achieved by integration of a gene under the transcription control of a promoter which is functional in the host and in which the transcribed strand of DNA is complementary to the strand of DNA that is transcribed from the endogenous β j -AR-specific polynucleotide sequence(s) one wishes to regulate. The integrated gene, referred to as an antisense gene, provides an RNA sequence capable of binding to naturally existing RNAs, exemplified by mammalian β r AR polypeptide-specific mRNA, and inhibiting its expression, where the anti-sense sequence may bind to the coding, non-coding, or both, portions of the RNA. The antisense construction may be introduced into the animal cell in a variety of ways and be integrated into the animal genome for inducible or constitutive transcription of the antisense sequence. Another aspect of the invention provides a pharmaceutical composition useful for inhibiting expression of mammalian β r AR-specific mRNA comprising a pharmaceutical carrier and one or more antisense oligonucleotides of the present invention that specifically bind to and reduce expression of the specific mRNA. Another aspect of the invention provides a method for treating hypertension in a human comprising administering to a subject an effective amount of at least one oligonucleotide composition as described herein, in an amount effective to reduce hypertension in the human, or to ameliorate the degree or extent of hypertension in the patient. 2.5 DEFINITIONS The term "βi-AR" refers to polypeptides having amino acid sequences which are substantially similar to the native mammalian βj-AR polypeptide amino acid sequences and which are biologically active and/or which cross-react with βι~AR polypeptide-specific antibodies raised against a mammalian βi-AR polypeptide or peptide fragment thereof. The term "β r AR" also includes analogs of mammalian β r AR polypeptides that exhibit at least some biological activity in common with native mammalian β r AR polypeptides. Furthermore, those skilled in the art of mutagenesis will appreciate that other analogs, as yet undisclosed or undiscovered, may be used to construct mammalian βi-AR polypeptide analogs or β r AR fusion proteins or identify βi-AR-related mRNAs and/or genes using well- known molecular biology techniques, including those described herein. Oligonucleotides complementary to mammalian βi-AR polypeptide-encoding mRNAs form the heart of the present invention, especially human β r AR polypeptide-encoding mRNAs. The oligonucleotides (or "ODNs" or "polynucleotides" or "oligos" or "oligomers" or "rø-mers") of the present invention are preferably deoxyoligonucleotides (i.e. DNAs), or derivatives thereof; ribo-oligonucleotides (i.e. RNAs) or derivatives thereof; or peptide nucleic acids (PNAs) or derivatives thereof. The term "substantially complementary," when used to define either amino acid or nucleic acid sequences, means that a particular subject sequence, for example, an oligonucleotide sequence, is substantially complementary to all or a portion of the selected sequence, and thus will specifically bind to a portion of an Mrna encoding a mammalian βj-AR polypeptide. As such, typically the sequences will be highly complementary to the Mrna "target" sequence, and will have no more than 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 base mismatches throughout the complementary portion of the sequence. In many instances, it may be desirable for the sequences to be exact matches, i.e. be completely complementary to the sequence to which the oligonucleotide specifically binds, and therefore have zero mismatches along the complementary stretch. As such, highly complementary sequences will typically bind quite specifically to the target sequence region of the Mrna and will therefore be highly efficient in reducing, and/or even inhibiting the translation of the target Mrna sequence into polypeptide product. Substantially complementary oligonucleotide sequences will be greater than about 80 percent complementary (or '% exact-match') to the corresponding Mrna target sequence to which the oligonucleotide specifically binds, and will, more preferably be greater than about 85 percent complementary to the corresponding Mrna target sequence to which the oligonucleotide specifically binds. In certain aspects, as described above, it will be desirable to have even more substantially complementary oligonucleotide sequences for use in the practice of the invention, and in such instances, the oligonucleotide sequences will be greater than about 90 percent complementary to the corresponding Mrna target sequence to which the oligonucleotide specifically binds, and may in certain embodiments be greater than about 95 percent complementary to the corresponding Mrna target sequence to which the oligonucleotide specifically binds, and even up to and including 96%, 97%, 98%, 99%, and even 100% exact match complementary to all or a portion of the target Mrna to which the designed oligonucleotide specifically binds. Percent similarity or percent complementary of any of the disclosed sequences may be determined, for example, by comparing sequence information using the GAP computer program, version 6.0, available from the University of Wisconsin Genetics Computer Group (UWGCG). The GAP program utilizes the alignment method of Needleman and Wunsch (1970). Briefly, the GAP program defines similarity as the number of aligned symbols (i.e., nucleotides or amino acids) that are similar, divided by the total number of symbols in the shorter of the two sequences. The preferred default parameters for the GAP program include: (1) a unary comparison matrix (containing a value of 1 for identities and 0 for non-identities) for nucleotides, and the weighted comparison matrix of Gribskov and Burgess (1986), (2) a penalty of 3.0 for each gap and an additional 0.10 penalty for each symbol in each gap; and (3) no penalty for end gaps. 2.6 EXEMPLARY ANTISENSE CONSTRUCTS FOR β r ADRENθCEPτoR-SPEciFic MRNA Table 1 lists representative oligonucleotide sequences contemplated for use in the practice of the present invention.

Rhesus monkey βj-AR-encoding mRNA is disclosed in GenBank™ accession number X75540, and described herein as SEQ ID NO:192. Murine (Mus) mouse βi-AR-encoding mRNA is disclosed in GenBank™ accession number LI 0084, and described herein as SEQ ID NO: 193. Highly homologous βj-AR-encoding DNAs have also been identified in non-mammalian species, such as frog (SEQ ID NO: 194) disclosed in GenBank™ as accession number Y09213, further evidence to the fact that antisense oligonucleotides prepared complementary to a β r AR-encoding DNA from one species may be useful in reducing the expression of βi-AR-specific mRNA in another species. In fact, the inventors contemplate that antisense oligonucleotides prepared complementary to highly conserved regions of the proximal portion of the βi-AR mRNA may specifically bind to, and reduce translation of, the mRNA in a variety of host cells and animals that produce β r adrenoceptor polypeptides. In the specification and claims, the letters, A, G, C, T, and U respectively indicate nucleotides in which the nucleoside is Adenosine (Ade), Guanosine (Gua), Cytidine (Cyt), Thymidine (Thy), and Uridine (Ura). As used in the specification and claims, compounds that are antisense to the βi-adrenoceptor-specific PNA, DNA or mRNA sense strand are compounds that have a nucleoside sequence complementary to the sense strand. Table 2 shows the four possible sense strand nucleosides and their complements present in an antisense compound. TABLE 2 Sense Antisense Ade Thy Gua Cyt Cyt Gua Thy Ade Ura Ade It will be understood by those skilled in the art that the present invention broadly includes oligonucleotide compounds that are capable of binding to the DNA or mRNA sense strand coding for BiR. It will also be understood that mRNA includes not only the ribonucleotide sequences encoding a protein, but also regions including the 5'-untranslated region, the 3'-untranslated region, the 5'-cap region and the intron/exon junction regions. The invention includes compounds which are not strictly antisense; the compounds of the invention also include those oligonucleotides that may have some bases that are not complementary to bases in the sense strand provided such compounds have sufficient binding affinity for β j -adrenoceptor DNA or mRNA to inhibit expression. In addition, base modifications or the use of universal bases such as inosine in the oligonucleotides of the invention are contemplated within the scope of the subject invention. The antisense compounds may have some or all of the phosphates in the nucleotides replaced by phosphorothioates (X=S) or methylphosphonates (X-CH 3 ) or other C M alkylphosphonates. The antisense compounds optionally may be further differentiated from native DNA by replacing one or both of the free hydroxy groups of the antisense molecule with Ci_ 4 alkoxy groups (R=Cι_ 4 alkoxy). As used herein, C M alkyl means a branched or unbranched hydrocarbon having 1 to 4 carbon-atoms. The disclosed antisense compounds also may be substituted at the 3' and/or 5' ends by a substituted acridine derivative. As used herein, "substituted acridine," means any acridine derivative capable of intercalating nucleotide strands such as DNA. Preferred substituted acridines are 2-methoxy-6-chloro-9-pentylaminoacridine, N-(6-chloro- 2-methoxyacridinyl)-O-methoxydiisopropylaminophosphinyl-3-aminopropanol, and N-(6-chloro2-methoxyacridinyl)-O-methoxydiisopropylaminophosphinyl-5-aminopentanol. Other suitable acridine derivatives are readily apparent to persons skilled in the art. Additionally, as used herein "P(O)(O) -substituted acridine" means a phosphate covalently linked to a substitute acridine. As used herein, the term "nucleotides" includes nucleotides in which the phosphate moiety is replaced by phosphorothioate or alkylphosphonate and the nucleotides may be substituted by substituted acridines. In one embodiment, the antisense compounds of the invention differ from native DΝA by the modification of the phosphodiester backbone to extend the life of the antisense ON. For example, the phosphates can be replaced by phosphorothioates. The ends of the molecule may also be optimally substituted by an acridine derivative that intercalates nucleotide strands of DNA. Intl. Pat. Appl. Publ. No. WO 98/13526 and U. S. Patent 5,849,902 (each specifically incorporated herein by reference in its entirety) describe a method of preparing three component chimeric antisense compositions, and discuss many of the currently available methodologies for synthesis of substituted oligonucleotides having improved antisense characteristics and/or half-life. The reaction scheme involves 'H-tetrazole-catalyzed coupling of phosphoramidites to give phosphate intermediates that are subsequently reacted with sulfur in 2,6-lutidine to generate phosphate compounds. Oligonucleotide compounds are prepared by treating the phosphate compounds with thiophenoxide (1:2:2 thiophenol/triethylamine/tetrahydrofuran, room temperature, 1 hr). The reaction sequence is repeated until an oligonucleotide compound of the desired length has been prepared. The compounds are cleaved from the support by treating with ammonium hydroxide at room temperature for 1 hr and then are further deprotected by heating at about 50°C overnight to yield preferred antisense compounds. The pharmaceutical preparations are made following conventional techniques of a pharmaceutical chemist involving mixing, granulating and compressing, when necessary, for tablet forms or mixing, filling, and dissolving the ingredients, as appropriate, to give the desired oral or parenteral products. Doses of the present compounds (in a pharmaceutical dosage unit as described above) will be an efficacious, nontoxic quantity selected from the range of 1 ng/kg to 500 mg/kg of active compound, preferably less than 10 mg/kg. The selected dose is administered to a human patient in need of inhibition of βi-AR-specifϊc mRNA expression from 1-6 or more times daily, orally, rectally, by injection, or continuously by infusion. Oral formulations would generally require somewhat larger dosages to overcome the effects of gastric decomposition. Intravenous or intra-arterial administration would generally require lower doses since the drug is placed directly into the systemic circulation. Dosages for nasal sprays typically range from about 10 mg to about 50 mg (total) or about 0.1 mg/kg to about 10 mg/kg. Therefore, the dose will depend on the actual route of administration. Selection of antisense compositions specific for a given gene sequence is based upon analysis of the chosen target sequence (i.e., in these illustrative examples the rat and human sequences) and determination of secondary structure, T m , binding energy, relative stability, and antisense compositions were selected based upon their relative inability to form dimers, haiφins, or other secondary structures that would reduce or prohibit specific binding to the target mRNA in a host cell. The results of these analyses are shown in Table 1, for illustrative oligonucleotides and selected target sequences identified in a variety of mammalian and non-mammalian sources. Highly preferred target regions of the mRNA, are those that are at or near the AUG translation initiation codon, and those sequences that were substantially complementary to 5' regions of the mRNA. These secondary structure analyses and target site selection considerations were performed using v.4 of the OLIGO primer analysis software (Rychlik, 1997) and the BLASTN 2.0.5 algorithm software (Altschul et al, 1997). The sequences of the oligonucleotides given above are highly preferred sequences for inhibiting mammalian βj-AR polypeptide activity in a host cell. Additional nucleotides at either end derived by the same process (using OLIGO and BLAST) are also envisioned by this invention. The effective lengths of the preferred oligonucleotides are preferably from at least 9 to about 35 or so nucleotides. The inventors contemplate all oligonucleotide compositions in this range (i.e., those of 9, 10, 11, 12, 13, 14, 15, 1,6, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, or 35 or so bases in length) are highly preferred for the practice of the oligonucleotide-based methods of the invention. In illustrative embodiments, the antisense compounds of the invention differ from native DNA by the modification of the phosphodiester backbone to extend the life of the antisense ODN, in which the phosphate substituents are replaced by phosphorothioates. Likewise, one or both ends of the oligonucleotide may be substituted by one or more acridine derivatives that intercalate between adjacent basepairs within a strand of nucleic acid. 4.2 METHODS FOR SCREENING PATIENTS AT RISK FOR HYPERTENSION Because mammalian β r AR polypeptide plays a key role in hypertension in an animal, it is often desirable to measure and quantitate levels of β r AR polypeptide in an animal under a variety of conditions, even during the course of a treatment regimen designed to ameliorate the hypertensive condition in such an animal. Likewise, in many instances, it is desirable to employ methods for screening polymorphisms of the gene encoding mammalian βi-AR, to identify patients "at risk" for hypertension, and to identify alleles of the gene both in vitro and in vivo. As such, the use of one or more of the nucleotide compositions described herein as a probe for identifying a gene encoding mammalian β ] -AR, and methods for correlating the presence of such nucleotide segments with the risk of hypertension is particularly desirable. 4.3 CO-ADMINISTRATION OF SMALL MOLECULE AND PEPTIDE INHIBITORS As described herein, in certain embodiments it may be desirable to co-administer one or more of the antisense compositions with one or more pharmaceuticals. For example, one or more of the commercially available anti-hypertensive agents may be co-administered in a particular therapeutic regimen. Such pharmaceuticals include, but are not limited to, amiloride, amlodipine, benazepril, bepridil, candesartan, captopril, chlorothiazide, chlorthalidone, dichloφhenamide, diltiazem, enalapril, ethacrynicacid, felodipine, fosinopril, furosemide, hydrochlorothiazide, hydroflumethiazide, irbesartan, isradipine, lisinopril, losartan, methylclothiazide, metolazone, misoldipine, moexipril, nicardipine, nifedepine, nimodipine, polythiazide, quinapril, ramipril, spironolactone, torsemide, trandolapril, triamterene, valsartan, and verapamil. Additional small molecular weight ACE inhibitory compounds and oligopeptides, such as those described in U. S. Patent 5,552,397; U. S. Patent 5,449,661; U. S. Patent 5,348,978; U. S. Patent 5,238,921; U. S. Patent 5,098,887 and U. S. Patent 4,216,209 (each specifically incoφorated herein by reference in its entirety). In certain embodiments, such small molecules or other anti-hypertensive agents may also be co-administered to an animal along with one or more of the disclosed antisense constructs. The administration of such anti-hypertensive agents or small molecular weight inhibitors is well known to those of skill in the art, and particular, to health practitioners who routinely diagnose and/or treat animals or patients suffering from hypertension. 4.4 PHARMACEUTICAL COMPOSITIONS Therefore, in certain embodiments, the present invention also concerns formulation of one or more of the antisense polynucleotide compositions disclosed herein in pharmaceutically acceptable solutions for administration to a cell or an animal, either alone, or in combination with one or more other modalities of antihypertensive therapy. It will also be understood that, if desired, the nucleic acid segment, RNA, DNA or PNA antisense compositions disclosed herein may be administered in combination with other agents as well, such as, e.g., proteins or polypeptides or various pharmaceutically-active agents. As long as the composition comprises at least one βi-AR-specific mRNA inhibitory antisense oligonucleotide, there is virtually no limit to other components that may also be included, given that the additional agents do not cause a significant adverse effect upon contact with the target cells or host tissues. The RNA, DNA, or PNA-derived antisense compositions may thus be delivered along with various other agents as required in the particular instance. Such RNA, DNA, or PNA antisense compositions may be purified from host cells or other biological sources, or alternatively may be chemically synthesized as described herein. Likewise, such compositions may comprise substituted or derivatized RNA, DNA, or PNA compositions. Such compositions may include modified peptide or nucleic acid substituent derivatives, as long as the base sequence of the RNA, DNA, or PNA molecule corresponds to one or more of the contiguous base sequences described herein that specifically bind to βi-AR-specific mRNA, and that reduce or inhibit the extent of translation of this mRNA into biologically-active βi-AR polypeptides. The formulation of pharmaceutically-acceptable excipients and carrier solutions are well-known to those of skill in the art, as is the development of suitable dosing and treatment regimens for using the particular compositions described herein in a variety of treatment regimens, including e.g., oral, parenteral, intravenous, intranasal, and intramuscular admimstration and formulation. 4.4.1 INJECTABLE DELIVERY Alternatively, the pharmaceutical compositions disclosed herein may be administered parenterally, intravenously, intramuscularly, or even intraperitoneally as described in U. S. Patent 5,543,158, U. S. Patent 5,641,515 and U. S. Patent 5,399,363 (each specifically incoφorated herein by reference in its entirety). Solutions of the active compounds as free- base or pharmacologically acceptable salts may be prepared in water suitably mixed with a surfactant, such as hydroxypropylcellulose. Dispersions may also be prepared in glycerol, liquid polyethylene glycols, and mixtures thereof and in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms. The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions (U. S. Patent 5,466,468, specifically incoφorated herein by reference in its entirety). In all cases the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms, such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol, and liquid polyethylene glycol, and the Hke), suitable mixtures thereof, and/or vegetable oils. Proper fluidity may be maintained, for example, by the use of a coating, such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial ad antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars or sodium chloride. Prolonged absoφtion of the injectable compositions can be brought about by the use in the compositions of agents delaying absoφtion, for example, aluminum monostearate and gelatin. For parenteral administration in an aqueous solution, for example, the solution should be suitably buffered if necessary and the liquid diluent first rendered isotonic with sufficient saline or glucose. These particular aqueous solutions are especially suitable for intravenous, intramuscular, subcutaneous and intraperitoneal administration. In this connection, sterile aqueous media that can be employed will be known to those of skill in the art in light of the present disclosure. For example, one dosage may be dissolved in 1 ml of isotonic NaCl solution and either added to 1000 ml of hypodermoclysis fluid or injected at the proposed site of infusion, (see for example, "Remington's Pharmaceutical Sciences" 15th Edition, pages 1035-1038 and 1570-1580). Some variation in dosage will necessarily occur depending on the condition of the subject being treated. The person responsible for administration will, in any event, determine the appropriate dose for the individual subject. Moreover, for human administration, preparations should meet sterility, pyrogenicity, and general safety and purity standards as required by FDA Office of Biologies standards. Sterile injectable solutions are prepared by incoφorating the active compounds in the required amount in the appropriate solvent with several of the other ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incoφorating the various sterilized active ingredients into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the preferred methods of preparation are vacuum-drying and freeze-drying techniques which yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof. The compositions disclosed herein may be formulated in a neutral or salt form. Pharmaceutically-acceptable salts, include the acid addition salts (formed with the free amino groups of the protein) and which are formed with inorganic acids such as, for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric, mandelic, and the like. Salts formed with the free carboxyl groups can also be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, histidine, procaine and the like. Upon formulation, solutions will be administered in a manner compatible with the dosage formulation and in such amount as is therapeutically effective. The formulations are easily administered in a variety of dosage forms such as injectable solutions, drug release capsules and the like. As used herein, "carrier" includes any and all solvents, dispersion media, vehicles, coatings, diluents, antibacterial and antifungal agents, isotonic and absoφtion delaying agents, buffers, carrier solutions, suspensions, colloids, and the like. The use of such media and agents for pharmaceutical active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in the therapeutic compositions is contemplated. Supplementary active ingredients can also be incoφorated into the compositions. The phrase "pharmaceutically-acceptable" refers to molecular entities and compositions that do not produce an allergic or similar untoward reaction when administered to a human. The preparation of an aqueous composition that contains a protein as an active ingredient is well understood in the art. Typically, such compositions are prepared as injectables, either as liquid solutions or suspensions; solid forms suitable for solution in, or suspension in, liquid prior to injection can also be prepared. The preparation can also be emulsified. 4.4.2 LIPOSOME-, NANOCAPSULE-, AND MICROPARTICLE-MEDIATED DELIVERY In certain embodiments, the inventors contemplate the use of liposomes, nanocapsules, microparticles, microspheres, lipid particles, vesicles, and the like, for the introduction of the antisense compositions of the present invention into suitable host cells. In particular, the antisense oligonucleotide compositions of the present invention may be formulated for delivery either encapsulated in a lipid particle, a liposome, a vesicle, a nanosphere, or a nanoparticle or the like. Such formulations may be preferred for the introduction of pharmaceutically acceptable formulations of the nucleic acids disclosed herein. The formation and use of Hposomes is generally known to those of skill in the art (see for example, Couvreur et al, 1977; Couvreur, 1988; Lasic, 1998; which describes the use of liposomes and nanocapsules in the targeted antibiotic therapy for intracellular bacterial infections and diseases). Recently, liposomes were developed with improved serum stability and circulation half-lives (Gabizon and Papahadjopoulos, 1988; Allen and Choun, 1987; U. S. Patent 5,741,516, specifically incoφorated herein by reference in its entirety). Further, various methods of liposome and liposome like preparations as potential drug carriers have been reviewed (Takakura, 1998; Chandran et al, 1997; Margalit, 1995; U. S. Patent 5,567,434; U. S. Patent 5,552,157; U. S. Patent 5,565,213; U. S. Patent 5,738,868 and U. S. Patent 5,795,587, each specifically incoφorated herein by reference in its entirety). Liposomes have been used successfully with a number of cell types that are normally resistant to transfection by other procedures including T cell suspensions, primary hepatocyte cultures and PC12 cells (Renneisen et al, 1990; Muller et al, 1990). In addition, liposomes are free of the DNA length constraints that are typical of viral-based delivery systems. Liposomes have been used effectively to introduce genes, drugs (Heath and Martin, 1986; Heath et al, 1986; Balazsovits et al, 1989; Fresta and Puglisi, 1996), radiotherapeutic agents (Pikul et al, 1987), enzymes (Imaizumi et al, 1990a; Imaizumi et al, 1990b), viruses (Faller and Baltimore, 1984), transcription factors and allosteric effectors (Nicolau and Gersonde, 1979) into a variety of cultured cell lines and animals. In addition, several successful clinical trails examining the effectiveness of liposome-mediated drug delivery have been completed (Lopez-Berestein et al, 1985a; 1985b; Coune, 1988; Sculier et al, 1988). Furthermore, several studies suggest that the use of liposomes is not associated with autoimmune responses, toxicity or gonadal localization after systemic delivery (Mori and Fukatsu, 1992). Liposomes are formed from phospholipids that are dispersed in an aqueous medium and spontaneously form multilamellar concentric bilayer vesicles (also termed multilamellar vesicles (MLVs). MLVs generally have diameters of from 25 nm to 4 μm. Sonication of MLVs results in the formation of small unilamellar vesicles (SUVs) with diameters in the range of 200 to 500 A, containing an aqueous solution in the core. Liposomes bear resemblance to cellular membranes and are contemplated for use in connection with the present invention as carriers for the peptide compositions. They are widely suitable as both water- and lipid-soluble substances can be entrapped, i.e. in the aqueous spaces and within the bilayer itself, respectively. It is possible that the drug-bearing liposomes may even be employed for site-specific delivery of active agents by selectively modifying the liposomal formulation. In addition to the teachings of Couvreur et al. (1977; 1988), the following information may be utilized in generating liposomal formulations. Phospholipids can form a variety of structures other than liposomes when dispersed in water, depending on the molar ratio of lipid to water. At low ratios the liposome is the preferred structure. The physical characteristics of liposomes depend on pH, ionic strength and the presence of divalent cations. Liposomes can show low permeability to ionic and polar substances, but at elevated temperatures undergo a phase transition which markedly alters their permeability. The phase transition involves a change from a closely packed, ordered structure, known as the gel state, to a loosely packed, less-ordered structure, known as the fluid state. This occurs at a characteristic phase-transition temperature, and results in an increase in permeability to ions, sugars, and drugs. In addition to temperature, exposure to proteins can alter the permeability of liposomes. Certain soluble proteins such as cytochrome c bind deform and penetrate the bilayer, thereby causing changes in permeability. Cholesterol inhibits this penetration of proteins, apparently by packing the phospholipids more tightly. It is contemplated that the most useful liposome formations for antibiotic and inhibitor delivery will contain cholesterol. The ability to trap solutes varies between different types of liposomes. For example, MLVs are moderately efficient at trapping solutes, but SUVs are extremely inefficient. SUVs offer the advantage of homogeneity and reproducibility in size distribution, however, and a compromise between size and trapping efficiency is offered by large unilamellar vesicles (LUVs). These are prepared by ether evaporation and are three to four times more efficient at solute entrapment than MLVs. Alternatively, the invention provides for pharmaceutically acceptable nanocapsule formulations of the polynucleotide compositions of the present invention. Nanocapsules can generally entrap compounds in a stable and reproducible way (Henry-Michelland et al, 1987; Quintanar-Guerrero et al, 1998; Douglas et al, 1987). To avoid side effects due to intracellular polymeric overloading, such ultrafine particles (sized around 0.1 μm) should be designed using polymers able to be degraded in vivo. Biodegradable polyalkyl-cyanoacrylate nanoparticles that meet these requirements are contemplated for use in the present invention, and such particles may be are easily made, as described (Couvreur et al, 1980; 1988; zur Muhlen et al, 1998; Zambaux et al. 1998; Pinto-Alphandry et al, 1995 and U. S. Patent 5,145,684, specifically incoφorated herein by reference in its entirety). In particular, methods of antisense oligonucleotide delivery to a target cell using either nanoparticles or nanospheres (Schwab et ah, 1994; Truong-Le et al, 1998) are also particularly contemplated to be useful in formulating the disclosed compositions for administration to an animal, and to a human in particular. 4.5 THERAPEUTIC AND DIAGNOSTIC KITS The invention also encompasses one or more of the antisense compounds together with one or more pharniaceuticaHy-acceptable excipients, carriers, diluents, adjuvants, and/or other components, such as additional antihypertensive agents, oligonucleotides, peptides, antigens, or other therapeutic compounds as may be employed in the formulation of particular oligonucleotide or polynucleotide delivery formulations, and in the preparation of antihypertensive agents or cardiac therapy for administration to an animal. As such, preferred animals for administration of the pharmaceutical compositions disclosed herein include mammals, and particularly humans. Other preferred animals include primates, sheep, goats, bovines, equines, porcines, lupines, canines, and felines, as well as any other mammalian species commonly considered pets, livestock, or commercially relevant species. The composition may include partially or significantly purified antisense compositions, either alone, or in combination with one or more additional active ingredients, which may be obtained from natural or recombinant sources, or which may be obtainable naturally or either chemically synthesized, or alternatively produced in vitro from recombinant host cells expressing nucleic acid segments encoding such additional active ingredients. Therapeutic kits may also be prepared that comprise at least one of the β r AR mRNA- specific antisense oligonucleotides and polynucleotides disclosed herein and instructions for using the composition as a therapeutic agent. The container means for such kits may typically comprise at least one vial, test tube, flask, bottle, syringe or other- container means, into which the antisense composition(s) may be placed, and preferably suitably aliquoted. Where a second antihypertensive agent is also provided, the kit may also contain a second distinct container means into which this second composition may be placed. Alternatively, the plurality of antihypertensive compositions may be prepared in a single pharmaceutical composition, and may be packaged in a single container means, such as a vial, flask, syringe, bottle, or other suitable single container means. The kits of the present invention will also typically include a means for containing the vial(s) in close confinement for commercial sale, such as, e.g., injection or blow-molded plastic containers into which the desired vial(s) are retained. Alternatively, for the preparation of diagnostic kits, and for methods relating to the use of these compounds in the identification of βj-AR polypeptide-encoding nucleic acids in a biological sample, such kits may be prepared that comprise at least one of the β r AR mRNA-specific antisense oligonucleotides disclosed herein and instructions for using the composition as a probe for βi-AR -specific nucleic acids in a hybridization assay. The container means for such kits may typically comprise at least one vial, test tube, microcentrifuge tube, or other container means, into which the antisense composition(s) may be placed and suitably aliquoted. Where a radiolabel or fluorigenic label or other such detecting means is included within the kit, the labeling agent may be provided either in the same container as the oligonucleotide composition, or may alternatively be placed in a second distinct container means into which this second composition may be placed and suitably aliquoted. Alternatively, the oligonucleotide composition and the label may be prepared in a single container means, and in most cases, the kit will also typically include a means for containing the vial(s) in close confinement for commercial sale and/or convenient packaging and delivery. 4.6 PEPTIDE NUCLEIC ACID COMPOSITIONS In certain embodiments, the inventors contemplate the use of peptide nucleic acids (PNAs) in the practice of the methods of the invention. PNA is a DNA mimic in which the nucleobases are attached to a pseudopeptide backbone (Good and Nielsen, 1997). PNAs may be utilized in a number of methods that traditionally have used RNA or DNA. Often PNA sequences perform better in techniques than the corresponding RNA or DNA sequences and have utilities that are not inherent to RNA or DNA. An excellent review of PNA including methods of making, characteristics of, and methods of using, is provided by Corey (1997) and is incoφorated herein by reference. As such, in certain embodiments, one may prepare PNA sequences that are complementary to one or more portions of the βj-adrenoceptor- specific mRNA sequence, and such PNA compositions may be used to regulate, alter, decrease, or reduce the translation of β r AR-specific mRNA, and thereby alter the level of βi-AR polypeptide in a host cell to which such PNA compositions have been administered. PNAs have 2-aminoethyl-glycine linkages replacing the normal phosphodiester backbone of DNA (Nielsen et al, 1993; Hanvey et al, 1992; Hyrup and Nielsen, 1996; Nielsen, 1995). This chemistry has three important consequences: firstly, in contrast to DNA or phosphorothioate oligonucleotides, PNAs are neutral molecules; secondly, PNAs are achiral, which avoids the need to develop a stereoselective synthesis; and thirdly, PNA synthesis uses standard Boc (Dueholm et al, 1992) or Fmoc (Bonham et al, 1995) protocols for solid-phase peptide synthesis, although other methods, including a modified Merrifield method, have been used (Christensen et al, 1995). PNA monomers or ready-made oligomers are commercially available from PerSeptive Biosystems (Framingham, MA, USA). PNA syntheses by either Boc or Fmoc protocols are straightforward using manual or automated protocols (Norton et al, 1995). 4.7 METHODS OF NUCLEIC ACID DELIVERY AND DNA TRANSFECTION In certain embodiments, it is contemplated that one or more RNA, DNA, PNAs and/or substituted polynucleotide compositions disclosed herein will be used to transfect an appropriate host cell. Technology for introduction of PNAs, RNAs, and DNAs into cells is well known to those of skill in the art. Several non-viral methods for the transfer of expression constructs into cultured mammalian cells also are contemplated by the present invention. These include calcium phosphate precipitation (Graham and Van Der Eb, 1973; Chen and Okayama, 1987; Rippe et al, 1990) DEAE-dextran (Gopal, 1985), electroporation (Wong and Neumann, 1982; Fromm et al, 1985; Tur-Kaspa et al, 1986; Potter et al, 1984; Suzuki et al., 1998; Vanbever et al, 1998), direct microinjection (Capecchi, 1980; Harland and Weintraub, 1985), DNA-loaded liposomes (Nicolau and Sene, 1982; Fraley et al, 1979; Takakura, 1998) and lipofectamine- DNA complexes, cell sonication (Fechheimer et al, 1987), gene bombardment using high velocity microprojectiles (Yang et al, 1990; Klein et al, 1992), and receptor-mediated transfection (Curiel et al, 1991; Wagner et al, 1992; Wu and Wu, 1987; Wu and Wu, 1988). Some of these techniques may be successfully adapted for in vivo or ex vivo use. Moreover, the use of viral vectors (Lu et al, 1993; Eglitis and Anderson, 1988; Eglitis et al, 1988), including retroviruses, baculoviruses, adenoviruses, adenoassociated viruses, vaccinia viruses, Heφes viruses, and the like are well-known in the art, and are described in detail herein. 4.8 EXPRESSION VECTORS The present invention contemplates an expression vector comprising at least one β j -AR -specific polynucleotide of the present invention. Thus, in one embodiment an expression vector is constructed with a specific DNA molecule orientated in the antisense direction. In another embodiment, a promoter is operatively linked to a sequence region that encodes a functional RNA such as a tRNA, a ribozyme or an antisense RNA. As used herein, the terms "operatively linked" and "operably linked" means that a promoter is connected to a functional DNA or RNA in such a way that the transcription of that functional DNA or RNA is controlled and regulated by that promoter. Means for operatively linking a promoter to a functional polynucleotides are well known in the art. The choice of which expression vector and ultimately to which promoter a polypeptide coding region is operatively linked depend directly on the functional properties desired, e.g., the location and timing of protein expression, and the host cell to be transformed. These are well known limitations inherent in the art of constructing recombinant DNA molecules. However, a vector useful in practicing the present invention is capable of directing the expression of the functional RNA to which it is operatively linked. RNA polymerase transcribes a coding DNA sequence through a site where polyadenylation occurs. Typically, DNA sequences located a few hundred base pairs downstream of the polyadenylation site serve to terminate transcription. Those DNA sequences are referred to herein as transcription-termination regions. Those regions are required for efficient polyadenylation of transcribed messenger RNA (mRNA). A variety of methods have been developed to operatively link DNA to vectors via complementary cohesive termini or blunt ends. For instance, complementary homopolymer tracts can be added to the DNA segment to be inserted and to the vector DNA. The vector and DNA segment are then joined by hydrogen bonding between the complementary homopolymeric tails to form recombinant DNA molecules. 4.9 IN VIVO DELIVERY AND TREATMENT PROTOCOLS To introduce the antisense constructs to cells in vivo, one of any number of conventional ways may be employed. These methods include viral-mediated delivery using retroviral, adenoviral, or adeno-associated viral vectors, and are well known to those of skill in the antisense therapeutic arts. Adeno virus vectors have been used in eukaryotic gene expression (Levrero et al, 1991; Gomez-Foix et al, 1992) and vaccine development (Grunhaus and Horwitz, 1992; Graham and Prevec, 1992). Recently, animal studies suggested that recombinant adenovirus could be used for gene therapy (Stratford-Perricaudet and Perricaudet, 1991; Stratford- Perricaudet et al, 1990; Rich et al, 1993). Studies in administering recombinant adenovirus to different tissues include trachea instillation (Rosenfeld et al, 1991; Rosenfeld et al, 1992), muscle injection (Ragot et al, 1993), peripheral intravenous injections (Herz and Gerard, 1993) and stereotactic inoculation into the brain (Le Gal La Salle et al, 1993). The retroviruses are a group of single-stranded RNA viruses characterized by an ability to convert their RNA to double-stranded DNA in infected cells by a process of reverse-transcription (Coffin, 1990). The resulting DNA then stably integrates into cellular chromosomes as a provirus and directs synthesis of viral proteins. The integration results in the retention of the viral gene sequences in the recipient cell and its descendants. The retroviral genome contains three genes, gag, pol, and env that code for capsid proteins, polymerase enzyme, and envelope components, respectively. A sequence found upstream from the gag gene contains a signal for packaging of the genome into virions. Two long terminal repeat (LTR) sequences are present at the 5' and 3' ends of the viral genome. These contain strong promoter and enhancer sequences and are also required for integration in the host cell genome (Coffin, 1990). AAV (Ridgeway, 1988; Hermonat and Muzycska, 1984) is a parovirus, discovered as a contamination of adenoviral stocks. It is a ubiquitous virus (antibodies are present in 85% of the U. S. human population) that has not been linked to any disease. It is also classified as a dependovirus, because its replication is dependent on the presence of a helper virus, such as adenovirus. Five serotypes have been isolated, of which AAV-2 is the best characterized. AAV has a single-stranded linear DNA that is encapsidated into capsid proteins VPl, VP2 and VP3 to form an icosahedral virion of 20 to 24 nm in diameter (Muzyczka and McLaughlin, 1988). The AAV DNA is approximately 4.7 kilobases long. It contains two open reading frames and is flanked by two ITRs. There are two major genes in the AAV genome: rep and cap. The rep gene encodes proteins responsible for viral replications, whereas the cap gene encodes the capsid protein VPl -3. Each ITR forms a T-shaped haiφin structure. These terminal repeats are the only essential cis components of the AAV for chromosomal integration. Therefore, the AAV can be used as a vector with all viral coding sequences removed and replaced by the cassette of genes for delivery. Three viral promoters have been identified and named p5, pi 9, and p40, according to their map position. Transcription from p5 and pi 9 results in production of rep proteins, and transcription from p40 produces the capsid proteins (Hermonat and Muzyczka, 1984). Other viral vectors may also be employed as expression constructs in the present invention for the delivery of βi-AR mRNA-complementary oligonucleotide sequences to a host cell. Vectors derived from viruses such as vaccinia virus (Ridgeway, 1988; Coupar et al, 1988), lentiviruses, polioviruses and heφesviruses may be employed. They offer several attractive features for various mammalian cells (Friedmann, 1989; Ridgeway, 1988; Coupar et al, 1988; Horwich et al, 1990). In order to effect expression of the β j -AR mRNA-complementary antisense sequences of the present invention, the expression construct must be delivered into a cell. This delivery may be accomplished in vitro, as in laboratory procedures for transforming cells lines, or in vivo or ex vivo, as in the treatment of certain disease states, and in particular, in the treatment of hypertension and βi-AR -related disorders. As described above, the preferred mechanism for delivery is via viral infection where the expression construct is encapsidated in an infectious viral particle. Once the expression construct has been delivered into the cell the nucleic acid encoding the β AR mRNA-complementary oligonucleotide antisense sequences may be positioned and expressed at different sites. In certain embodiments, the nucleic acid encoding the antisense construct may be stably integrated into the genome of the cell. This integration may be in the specific location and orientation via homologous recombination (gene replacement) or it may be integrated in a random, non-specific location (gene augmentation). In yet further embodiments, the nucleic acid may be stably maintained in the cell as a separate, episomal segment of DNA. Such nucleic acid segments or "episomes" encode sequences sufficient to permit maintenance and replication independent of or in synchronization with the host cell cycle. How the expression construct is delivered to a cell and where in the cell the nucleic acid remains is dependent on the type of expression construct employed. In one embodiment of the invention, the expression construct comprising one or more βi-AR mRNA-complementary oligonucleotide or polynucleotide antisense sequences may simply consist of naked recombinant DNA or plasmids. Transfer of the construct may be performed by any of the methods mentioned above which physically or chemically permeabilize the cell membrane. This is particularly applicable for transfer in vitro but it may be applied to in vivo use as well. Dubensky et al. (1984) successfully injected polyomavirus DNA in the form of calcium phosphate precipitates into liver and spleen of adult and newborn mice demonstrating active viral replication and acute infection. Benvenisty and Reshef (1986) also demonstrated that direct intraperitoneal injection of calcium phosphate-precipitated plasmids results in expression of the transfected, genes. It is envisioned that DNA encoding a gene of interest may also be transferred in a similar manner in vivo and express the gene product. Another embodiment of the invention for transferring a naked DNA expression construct into cells may involve particle bombardment. This method depends on the ability to accelerate DNA-coated microprojectiles to a high velocity allowing them to pierce cell membranes and enter cells without killing them (Klein et al, 1987). Several devices for accelerating small particles have been developed. One such device relies on a high voltage discharge to generate an electrical current, which in turn provides the motive force (Yang et al, 1990). The microprojectiles used have consisted of biologically inert substances such as tungsten or gold beads. Selected organs including the liver, skin, and muscle tissue of rats and mice have been bombarded in vivo (Yang et al, 1990; Zelenin et al, 1991). This may require surgical exposure of the tissue or cells, to eliminate any intervening tissue between the gun and the target organ i.e., ex vivo treatment. Again, DNA encoding a particular gene may be delivered via this method and still be incoφorated by the present invention. In a further embodiment of the invention, the expression construct comprising an βi-AR mRNA-complementary oligonucleotide antisense sequence may be entrapped in one or more nanocapsules, liposomes, or other lipid based DNA delivery agent. Liposomes are vesicular structures characterized by a phospholipid bilayer membrane and an inner aqueous medium. Multilamellar liposomes have multiple lipid layers separated by aqueous medium. They form spontaneously when phospholipids are suspended in an excess of aqueous solution. The lipid components undergo self-rearrangement before the formation of closed structures, and entrap water and dissolved solutes between the lipid bilayers (Ghosh and Bachhawat, 1991). Also contemplated are Hpofectamine-DNA complexes. Liposome-mediated nucleic acid delivery and expression of foreign DNA in vitro has been very successful. Wong et al. (1980) demonstrated the feasibility of liposome-mediated delivery and expression of foreign DNA in cultured chick embryo, HeLa and hepatoma cells. Nicolau et al. (1987) accomplished successful liposome-mediated gene transfer in rats after intravenous injection. In certain embodiments of the invention, the liposome may be complexed with a hemagglutinating virus (HVJ). This has been shown to facilitate fusion with the cell membrane and promote cell entry of liposome-encapsulated DNA (Kaneda et al, 1989). In other embodiments, the liposome may be complexed or employed in conjunction with nuclear non-histone chromosomal proteins (HMG-1) (Kato et al, 1991). In yet further embodiments, the liposome may be complexed or employed in conjunction with both HVJ and HMG-1. In that such expression constructs have been successfully employed in transfer and expression of nucleic acid in vitro and in vivo, then they are applicable for the present invention. Where a bacterial promoter is employed in the DNA construct, it also will be desirable to include within the liposome an appropriate bacterial polymerase. Other expression constructs that may be employed to deliver an antisense polynucleotide into a target cell include receptor-mediated delivery vehicles. These take advantage of the selective uptake of macromolecules by receptor-mediated endocytosis in almost all eukaryotic cells. Because of the cell type-specific distribution of various receptors, the delivery can be highly specific (Wu and Wu, 1993). Receptor-mediated gene targeting vehicles generally consist of two components: a cell receptor-specific ligand and a DNA-binding agent. Several ligands have been used for receptor-mediated gene transfer. The most extensively characterized ligands are asialoorosomucoid (ASOR) (Wu and Wu, 1987) and transferrin (Wagner et al, 1993). Recently, a synthetic neoglycoprotein, winch recognizes the same receptor as ASOR, has been used as a gene delivery vehicle (Ferkol et al, 1993; Perales et al, 1994) and epidermal growth factor (EGF) has also been used to deliver genes to squamous carcinoma cells (Eur. Pat. Appl. Publ. No. EP0273085, specifically incoφorated herein by reference in its entirety). In other embodiments, the delivery vehicle may comprise a ligand and a liposome. For example, Nicolau et al. (1987) employed lactosyl-ceramide, a galactose-terminal asialganglioside, incoφorated into liposomes and observed an increase in the uptake of the insulin gene by hepatocytes. Thus, it is feasible that a nucleic acid encoding a particular gene also may be specifically delivered into a cell type such as lung, epithelial or tumor cells, by any number of receptor-ligand systems with or without liposomes. For example, epidermal growth factor (EGF) may be used as the receptor for mediated delivery of a nucleic acid encoding a gene in many tumor cells that exhibit upregulation of EGF receptor. Mannose can be used to target the mannose receptor on liver cells. Also, antibodies to CD5 (CLL), CD22 (lymphoma), CD25 (T-cell leukemia) and MAA (melanoma) can similarly be used as targeting moieties. In certain embodiments, gene transfer may more easily be performed under ex vivo conditions. Ex vivo gene therapy refers to the isolation of cells from an animal, the delivery of a nucleic acid into the cells in vitro, and then the return of the modified cells back into an animal. This may involve the surgical removal of tissue/organs from an animal or the primary culture of cells and tissues. Anderson et αl, U.S. Patent 5,399,346, and incoφorated herein in its entirety, disclose ex vivo therapeutic methods. 5.0 EXAMPLES The following examples are included to demonstrate preferred embodiments of the invention. It should be appreciated by those of skill in the art that the techniques disclosed in the examples which follow represent techniques discovered by the inventor to function well in the practice of the invention, and thus can be considered to constitute preferred modes for its practice. However, those of skill in the art should, in light of the present disclosure, appreciate that many changes can be made in the specific embodiments which are disclosed and still obtain a like or similar result without departing from the spirit and scope of the invention. 5.1 EXAMPLE 1 - ANTISENSE INHIBITION OF β r AR MRNA βi-antisense, through specific inhibitions of βj-AR expression, decreases the functional sensitivity of βi-AR-mediated responses in the face of sympathetic activation and thereby achieves an antihypertensive effect. In this example, an AS -ODN was designed complementary to rat βi-AR mRNA and its ability was demonstrated to inhibit β r AR density and function in the heart and to reduce BP in spontaneously hypertensive rats. 5.1.1 METHODS 5.1.1.1 ANTISENSE DESIGN AND ADMINISTRATION A 15-mer AS-ODN and a 15-mer inverted ODN control were synthesized and targeted to the AUG start codon of rat β,-AR mRNA (Machida et αl., 1990). The sequence of the AS-ODN was 5'-CCGCGCCCATGCCGA-3* (SEQ ID NO: 195), and the sequence of the inverted ODN was 5'-AGCCGTACCCGCGCC-3' (SEQ ID NO: 196). This AS-ODN was chosen from 6 AS candidates targeted to different regions of β]-AR mRNA on the basis of the intensity of cardiac β r AR inhibition and reduction of BP in SHRs. These oligonucleotides were modified by backbone phosphorothioation. ODNs delivered with cationic liposomes were injected into the tongue vein. 5.1.1.2 PREPARATION OF LIPOSOMES AND ODN/LIPOSOME COMPLEX The cationic lipid l,2-bis(oleoyloxy)-3-(trimethylammonio)propane (DOTAP) was mixed with helper lipid 1-α-dioleoyl phosphatidylethanolamine (DOPE, Avanti Polar Lipids, Alabaster, AL) at a 1:1 molar ratio, briefly sonicated, and stored at 4°C until use. The average diameter of liposomes is 200 to 300 nm (Tang and Hughes, 1998). ODN/liposome complex was prepared on the day of use by mixing the desired amounts of ODNs with DOTAP/DOPE to the final DNA concentration of 300 μg/mL in 5% wt./vol. dextrose in water and incubating at room temperature for 60 min. Two DNA lipid molar ratios, i.e. 1 :0.5 and 1 :2.5, were used in the studies. 5.1.1.3 ANIMAL SURGERY Adult male SHRs (250 to 350 g, Harlan, Indianapolis, IN) were kept in cages in a room with a 12-hr. light-dark cycle. Animals were fed standard laboratory rat chow and tap water ad libitum. 5.1.1.4 TELEMETRIC SENSOR IMPLANTATION Before implantation, the zero of each radiotransmitter (TA11PA-C40, Data Sciences, St. Paul, MN) was verified to be < 4 mm Hg. SHRs were anesthetized with 100 mg/kg ketamine and 15 mg/kg xylazine, and a midline abdominal incision was made. A fluid-filled sensor catheter was then inserted into the right femoral artery, and the tip of the catheter was in the abdominal aorta caudal to the renal arteries. The rats with implants were allowed to recover for 1 week. 5.1.1.5 JUGULAR VEIN CANNULATION One week after telemetric implantation, rats were anesthetized, and a curved catheter made of PE 50 and vinyl tubing was inserted into a curved catheter made of PE 50 and vinyl tubing was inserted into the jugular vein. The tubing was led under the skin of the neck and exposed on the back to allow for drug infusion. Rats were allowed to recovery for 24 hr before experimentation. The catheters were flushed with 100 U heparin every day to prevent clogging. 5.1.1.6 MEMBRANE PREPARATION AND β-AR BINDING ASSAY Four days after intravenous injection of saline (n=6) or 1 mg/kg inverted ODN (n=6) or 2, 4, 10 or 18 days after injection of 1 mg/kg β r AS-ODN (n=24), animals were euthanized, and membranes were prepared from heart ventricles as previously described (Baker and Pitha, 1982). For saturation studies, 100 μg membrane protein was incubated in triplicate with 6 concentrations of [ 125 I]Q-iodocyanopindolol (ICYP, NEN Life Science, 6.25 to 100 pmol/L) in a total volume of 250 μL containing 50 mmol/L Tris-HCI (pH 7.4), 5 mmol/L MgCl 2 at 36°C for 60 min. The nonspecific and β 2 -AR-binding levels were determined in the presence of 1 μmol/L (±)-alprenolol and 150 nmol/L CGP20712A (RBI), respectively. Then the reaction mixture was passed through Whatman (GF/B glass fiber filter using a Brandel harvester, and the bound radioactivity was counted for 1 min. 5.1.1.7 TISSUE PREPARATION AND QUANTITATIVE AUTORADIOGRAPHY Four days after injection of 1 mg/kg β AS-ODN (n=6) or saline (n=6), rats were killed, and tissues were removed and frozen in dry ice. Coronal sections of brain, horizontal sections of heart, and sagittal sections of kidney (20 μm) were cut on a cryostat (Microm, Thornwood, NY) at " 20°C and mounted on microscope slides. Every seventh slide was stained with hematoxylin and eosin for histology. Tissue sections were preincubated in Krebs buffer (mmol/L: NaCl 118.4, KCl 4.7, MgSO 4 1.2, CaCl 2 1.27 and NaH 2 PO 4 10.0, pH 7.1) containing 0.1 mmol/L GTP, 0.1 mmol/L ascorbic acid, and 10 μmol/L PMSF for 30 minutes at 25°C. Sections were then incubated in Krebs buffer containing 0.1 mmol/L ascorbic acid and 10 μmol/L PMSF with 100 pmol/L ICYP at 25°C for 150 minutes in the presence of 1 μmol/L ( " ) propranolol, 100 nmol/L ICI 118,551 (β r selective antagonist), or 100 nmol/L CGP20712A (βi-selective antagonist) to distinguish nonspecific, β j. , and β 2 - bindings. Labeled sections were rinsed in the same buffer, followed by two 15-min. washes at 37°C in the buffer, and rinsed in distilled water at 25°C (Matthews et al, 1994). Dried sections were then exposed to x-ray films. The images were quantified with a computerized image analysis system (MCID, Imaging Research) and normalized with 125 I standards. Nonspecific binding was <10% of total binding. 5.1.1.8 DETERMINATION OF EFFECTS OF β r AS AND ATENOLOL ON CARDIOVASCULAR PARAMETERS IN RESPONSE TO β-SτiMULAτιθN 48 hr after injection of 1 mg/kg β,-AS-ODN (n=9) or inverted ODN (n=6), SHRs were anesthetized and killed. Hearts were quickly removed and perfused via the aorta with oxygenated Krebs buffer (118 mmol/L NaCl, 18.75 mmol/L NaHCO 3 1.2 mmol/L KH 2 PO 4 , 4.7 mmol/L KCl, 1.2 mmol/L MgSO 4 , 1.25 mmol/L CaCl 2 , 11.1 mmol/L glucose, and 0.01 mmol/L EDTA) at a constant flow of 7.0 mL/min. at 36°C. Coronary perfusion pressure was measured via a catheter placed proximal to the aorta and connected to a pressure transducer (Gould Staham P23ID, Eastlake, OH). A latex balloon filled with water and connected to the pressure transducer was inserted into the left ventricle through the left atrium to measure left ventricular end-diastolic pressure (LVEDP), left ventricular systolic pressure (LVSP), and developed left ventricular pressure (dLVP) (dLVP=LVSP-LVEDP). LVEDP during equilibration was set at 5 to 7 mm Hg. Coronary perfusion pressure, LVEDP, and LVSP were recorded continuously on a 4-channel recorder (Astro-Med, West Warwick, RI). After baseline values for dLVP and heart rate (HR) were stable for 5 min., isoproterenol (ISO, nonspecific β-agonist) was given at 0.01, 0.025, 0.05, and 0.12 μmol/L at 10 min. intervals so as to avoid the effect of tachyphylaxis. The effects of β r AS-ODN and atenolol on cardiac dP/dt,^, and systolic blood pressure (SBP) were compared in the same group of SHRs (n=4). Two days after catherization of the jugular vein, control values were taken and 1 mg/kg β,-AS-ODN was injected. 48 hr later, rats were tested for the effect of β r AS-ODN. The rats were allowed to recover until all the cardiovascular parameters returned to control values. Then 1 mg/kg atenolol (β r selective antagonist) was injected, and rats were tested 30 min. later. For β r stimulation, SHRs were infused with dobutamine (βj-selective agonist) through a jugular vein catheter at 5, 10, 20, and 40 μg • kg "1 • min. "1 . Each dose was given for 5 min. continuously and at 1-hr intervals until all the cardiovascular parameters returned to baseline values so as to avoid the effect of tachyphylaxis. BP and HR were sampled every 1 min. dP/dt max was calculated from the slope of the rising pulse-pressure curve and determined every 1 min. The difference between values at each dose and baseline was denoted as Δ. 5.1.1.9 BP MONITORING Each rat cage was placed on a receiver (RLA 1020, Data Sciences, St. Paul, MN) for measurement of cardiovascular parameters. Data were collected with a computer-based data acquisition program (Dataquest Lab-PRO3.0; Data Sciences). BP and HR were measured every 10 min. and averaged every 1 to 24 hrs. Before treatment, SHRs were monitored for a week to get a stable baseline. Rats were warmed for 20 to min. in cages on heating pads. The temperature was controlled at 35°C to 37°C. Then the rats were placed in a plastic restrainer kept at 37°C. A pneumatic pulse sensor was attached to the tail. After cuff inflation, SBP was determined as the first pulsatile oscillation on the descending side of the pressure curve. HR was determined by manual counting of pulse numbers per unit time. BP and HR were recorded by a Narco physiograph. Data values of each rat were taken as an average of at least 4 stable readings. Baseline was determined by averaging 3 days of measurements before antisense administration. 5.1.1.10 STATISTICAL ANALYSIS Values were expressed as mean ±SEM. The difference was considered statistically significant at PO.05. An unpaired t test was used to compare B max , dLVP, and BP in 2 groups. One-way repeated-measures ANOVA and Tukey test were used to compare ΔdP/dt and ΔHR on dobutamine infusion in different groups. Pearson product-moment correlation was used to assess the relationship between β r AR B max and dLVP. 5.1.2 RESULTS 5.1.2.1 EFFECT ON CARDIAC β-AR DENSITY FIG. 1A shows that a single intravenous injection of 1 mg/kg β]-AS-ODN delivered with cationic liposomes at a 1:2.5 molar ratio significantly reduced the βj-AR density in the SHR hearts for 18 days (PO.01). The drop was at its maximum of 47% on day 4, 33% on day 10 and maintained at 29% on day 18. In contrast, there was no significant change in the B max of β 2 -ARs. The K Ό of both subtypes remained unaltered (Table 1). Consequently, the βι/β 2 subtype ratio in the ventricles was diminished from « 70/30 to « 50/50 by βi-AS-ODN. Inverted ODN had no effect on either subtype (FIG. IB). 5.1.2.2 EFFECT ON CARDIAC CONTRACTILITY AND HR IN RESPONSE TO β- STIMULATION 48 hr after injection of lmg/kg β r AS-ODN, the cardiac inotropic and chronotropic responses to β-stimulation were determined in SHRs in vitro and in vivo. First, isolated hearts were perfused with incrementing doses of ISO, which enhanced HR and contractility via activating β-ARs. The dLVP -ISO dose-response curve, which reflected the positive inotropic effect of ISO, was significantly shifted downward by β, -AS- ODN (PO.02). HR was not significantly decreased, except at 1 point, i.e. 0.01 μmol/L ISO (PO.05) (FIG. 2A and FIG. 2B). An in vivo test was performed in conscious SHRs monitored by radiotelemetry. β r AS-ODN significantly (PO.02) dampened the increase in dP/dt max in the face of dobutamine (βi-selecrive agonist) (FIG. 3A). The change in HR was not significantly reduced (FIG. 3B), which echoed the results in isolated perfused hearts. Conversely, the response of BP to dobutamine was biphasic (FIG. 3C). Dobutamine elevated SBP by 5 to 8 mm Hg at low infusion speed and reduced SBP at higher speed, probably as a result of the partial β 2 - agonistic activity of dobutamine at high doses and the consequent vasodilatory effect on BP. FIG. 3 also compares the results with β r AS-ODN and atenolol (β j -selective antagonist). Relative to β r AS-ODN, 1 mg/kg atenolol produced a more profound decline in Δ.d¥ldt m!Si and ΔHR during a 5 hr. period of time after injection. Moreover, it reduced basal dP/dt^ (2450 ± 295 mm Hg/s versus control, 2937 ± 277 mm Hg/s) and caused bradycardia (295 ± 12 bpm versus control, 365 ± 8 bpm) (PO.05), whereas β r AS did not change basal contractility (2922 ± 249 mm Hg/s) or HR (365 ± 12 bpm). But the effects of atenolol on ΔdP/dt^ and ΔHR were transient. Within 24 hr after atenolol admimstration, the inotropic and chronotropic effects of dobutamine had returned to control levels.

AS-ODN was delivered with cationic liposomes at different molar ratios of DNA/lipid, i.e. 1:0.5 and 1:2.5. β r AS-ODN delivered with liposomes at a 1 :0.5 ratio diminished SBP for 8 days. The maximum drop was 38 + 5 mm Hg. When the molar ratio was increased to 1:2.5, this hypotensive effect was drastically prolonged to 20 days. No effect was seen with inverted ODN. To compare the effects of β r AS-ODN and atenolol, radiotelemetry was used to monitor BP and HR on a regular basis. β j -AS-ODN 1 mg/kg delivered with liposomes at a 1:0.5 ratio produced a maximum drop of 15 mm Hg in mean BP (FIG. 5A). The antihypertensive effect lasted for 8 days, which was consistent with the results measured with the tail cuff. HR was not significantly altered (FIG. 5B). In contrast to AS-ODN, although the onset of the hypotensive effect caused by 1 mg/kg atenolol occurred as early as 20 min. after injection, it lasted for only 10 hr (FIG. 6A). In addition, atenolol caused considerable bradycardia up to an average of " 75 bpm (FIG. 6B). 5.1.2.4 EFFECT ON β-AR DISTRIBUTION IN BRAIN, HEART, AND KIDNEY Quantitative autoradiography of 6 to 18 tissue slices in brain, heart, and kidney was analyzed 4 days after intravenous β r AS-ODN administration. No changes in the distribution of β-ARs in the forebrain and brain stem regions were detected. This indicated the absence of antisense effect on the β-AR expression in CNS. However, βj-AS-ODN significantly (PO.05) reduced β r AR density in cardiac ventricles (from 30.2 ± 2.1 to 20.6 ± 2.5 fmol/mg) and renal cortex (from 26.4 ± 3.1 to 17.4 + 3.3 frnol/mg). This was consistent with the binding results. β 2 -ARs were not affected in any tissues. 5.1.3 DISCUSSION This example compares the effects of a novel β r AS-ODN on high BP in a model of hypertension with a currently used β-blocker. β r AS-ODN knocked down βi-adrenergic activity, resulting in long-term attenuation of BP. The results indicated that β,-AS-ODN reduced βi-AR density and cardiac contractility after βj -stimulation in vitro and in vivo and lowered high BP of SHRs. These findings are consistent with the hypothesis that βi-AS, through the inhibition of βi-AR expression, is able to render heart, kidney, and other tissues less sensitive to sympathetic activation, which is a major contributing factor in high BP. A single injection of β r AS-ODN effectively decreased the cardiac β r AR density, which was accompanied by diminished ventricular contractility and cardiac output in response to β- stimulation. The antihypertensive effect in SHRs was up to a 38 mm Hg reduction lasting as long as 20 days. Treatment of βj-AS-ODN reduced cardiac βi-AR density by «50% in 4 days. Considerable variation is reported in the literature on the half-life of βj-ARs (Baker and Pitha, 1982; Neve and Molinoff, 1986 and Winter et al, 1988). From the results with the AS-ODN inhibition, the half-life of cardiac β j -ARs is « 2 to 4 days to allow for 50% reduction of β-AR density within 4 days. Both tail-cuff and telemetry measures of BP showed a significant drop after antisense treatment. SHRs responded to β AS-ODN to a greater degree of hypotension when subjected to tail cuff vs. telemetry. In addition, the baseline measured with the tail cuff was consistently higher than that with telemetry by 20 to 30 mm Hg in the same rats. Bazil et al, 1993 reported a similar phenomenon. They compared the cardiovascular parameters recorded by telemetry, tail cuff, and arterial catheter and observed a more sensitive hypotensive effect of captopril with tail cuff. Tail-cuff measurement of BP involves warming and restraint of rats. It is conceivable that βi-AS, through the suppression of sympathetic activity, can decrease the BP of animals under stress more effectively. Cationic liposomes are effective vehicles for gene delivery. It has been shown that liposomes entrapment not only improves the cellular uptake of DNA but also protects DNA from degradation and extends its circulation time (Allen, 1997; Liu et al, 1997). Numerous factors influence the efficiency of cationic liposome-mediated intravenous gene delivery, such as DNA/lipid ratio, selection of lipids, and preparation procedure. A widely used lipid formula, DOTAP/DOPE, was used to deliver β r AS-ODN at 4 molar ratios. The optimal ratio of 1:2.5 was determined on the basis of the duration and magnitude of the antihypertensive effects. A profound and prolonged fall in BP of 38 mm Hg up to 20 days was achieved at this ratio, which followed the reduction in βi-AR binding to a maximum of 47% at day 4, 33% at day 10, and 29% at day 18. This implies that β,-AS-ODN effectively inhibits the functionally active receptors involved in the BP. The blood-brain barrier formed by capillary endothelia is permeable only to small lipophilic molecules with a molecular weight of <600 Da (reviewed by Pardridge, 1998). Owing to their high hydrophilicity, ODNs undergo negligible transport through blood-brain barrier and have very limited access to CNS. The cellular and organ distributions of DNA/liposome complexes with fluorescent labeling were previously studied in mice after intravenous injection, and the results indicated that the complexes were taken up primarily by capillary endothelial cells in most of the peripheral organs, including lung, heart, kidney, and spleen, but were absent in the brain (McLean et al, 1997). Although brain retention of liposomes after peripheral administration was observed in some cases, it was due to entrapment within the brain micro vasculature (Schackert et al, 1989). Autoradiography in brain revealed no detectable changes in the expression and distribution of β-ARs after intravenous βj- AS-ODN injection. This provided further evidence that the use of antisense did not have CNS effects. High specificity based on gene sequence has made antisense an increasingly useful tool in numerous studies and clinical trials. Its success is manifested by the recent approval of the first antisense drug, Vitavene, by the Food and Drug Administration. However, sequence-independent interactions have also been reported with AS-ODNs. High doses are usually responsible for the nonspecific effects (Chang et al, 1989), but another possible reason is that currently available databases do not cover every gene; thus, homology comparison by BLAST search may no guarantee sequence specificity of AS-ODNs. In this study, βi-AS-ODN inhibited βi-AR expression without changing β 2 -ARs. Although this is likely due to the specificity of the β r AS-ODN sequence, other possibilities remain, such as indirect effects on regulatory mechanisms. In patients with chronic heart failure, the severity of the disease closely relates to the decrease in cardiac β-AR density and functional responsiveness (Brown et al, 1992). In SHRs treated with β r AS-ODN, a marked attenuation of the β r AR-mediated positive inotropic response in vitro and in vivo, concurrent with the diminished cardiac β r AR level. Therefore, these results indicated a positive correlation between cardiac β r AR number and functional sensitivity (correlation coefficient >0.90, PO.01). Despite the large decrease in BP, no reflex tachycardia was observed after antisense treatment. However, the suppressive effect of βi-AS-ODN on Hr was less significant than its negative inotropic response. Several possibilities can be considered. First, β j -AS-ODN did not affect β 2 -ARs, which played an important role in the regulation of HR (Kaumann, 1986; Rodefeld et al, 1996), although it was not involved in the cardiac contraction. Second, antisense inhibition of β r AR expression is gradual and less extensive than with β-blockers. It is also possible that β j -ARs may have a larger reserve for controlling HR than contractility. 5.2 EXAMPLE 2 ~ PROLONGED REDUCTION IN HIGH BLOOD PRESSURE WITH βi AR OLIGODEOXYNUCLEOTIDES Since the introduction of propranolol in 1965, β-blockers have become major first- line drugs for hypertension. Through the inhibition of β-adrenergic receptors in heart and kidney, β-blockers lower high blood pressure via the reduced response to the sympathetic nervous system. However, all current β-blockers have to be taken daily. Also, most have central nervous system side effects that lead to poor patient compliance. Furthermore, the mechanism of β-blockade in hypertension is not well understood (Man in't Veld et al, 1988). Antisense oligonucleotides have been successfully constructed to components of the renin-angiotensin system (RAS) to decrease blood pressure (Phillips et al, 1994). In view of this, novel antisense oligonucleotides targeted to β r adrenergic receptors (β 2 -ARs), or the brain. Therefore, it is likely to have fewer side effects and longer-lasting action. It has been previously shown that antisense oligodeoxynucleotide (β j -AS-ODN) significantly inhibits β r AR expression in the cardiac ventricles, which results in suppressed inotropic response to adrenergic activation and thereby contributes to hypotension. In addition to inducing positive inotropy and chronotropy in the heart, β r ARs are also responsible for mediating the sympathetic stimulation of renin expression and secretion from juxtaglomerular cells of the renal cortex. Infusion of isoproterenol has been shown to increase renin expression and secretion and plasma renin activity (PRA) in rats (Holmer et al, 1997). β-Blockers reduce PRA in patients, (Blumenfeld et al, 1999). However, despite the evidence that β-blockers are more effective in patients with high renin profiles (Buhler, 1988), the importance of β-blocker-induced decreases in renin release has been debated (Man in't Veld et al, 1983). The present study investigates whether β r AS-ODN reduces renin expression and secretion and whether the RAS is involved in the antihypertensive impact of βi-AS-ODN could be improved by delivery with cationic liposomes and to determine the optimal charge ratio of Hposome:ODN. 5.2.1 METHODS 5.2.1.1 ANTISENSE SEQUENCE AND DELIVERY AS-ODN and inverted ODN control were 15-mer and targeted to the AUG start codon of rat β r AS-ODN is 5'-CCGCGCCCATGCCGA-3' (SEQ ID NO: 197), and the inverted ODN is 5*-AGCCGTACCCGCGCC-3' (SEQ ID NO: 198). These ODNs were modified by backbone phosphorothioation. The cationic lipid l,2-bis(oleoyloxy)-3- (trimethylammonio)propane (DOTAP) mixed with the helper lipid L- -dioleoyl phosphatidylethanolamine (DOPE, Avanti Polar Lipids) at 1:1 molar ratio was used to deliver ODNs in a single intravenous injection into the tongue vein. ODN-liposome complex was prepared on the day of use by mixing desired amounts of ODNs with DOTAP/DOPE to a final DNA concentration of 300 μg/mL in 5% (wt./vol.) dextrose in water and incubating at room temperature for 60 min. 5.2.1.2 ANIMALS Adult male SHR (4 to 6 mos. old, Harlan, Indianapolis, IN) were kept in cages in a room with a 12 hr. light-dark cycle. Animals were fed standard laboratory rat chow and tap water ad libitum. Tail blood was collected for determination of PRA and angiotensin II (Ang II) levels. 5.2.1.3 BLOOD PRESSURE MEASUREMENT Blood pressure was measured by the tail-cuff method as described above. Systolic blood pressure (SBP) was determined as the first pulsatile oscillation on the descending side of the pressure curve. Data values of each rat were taken as an average of >4 stable readings. Baseline was determined by averaging 3 days of measurements before antisense admimstration. 5.2.1.4 MEMBRANE PREPARATION AND β-ADRENERGic RECEPTOR BINDING ASSAY Four days after intravenous injection of saline (n=6) or 0.5 mg/kg inverted ODN (n=6) or 4, 10, 18 and 40 days after injection of 0.5 mg/kg β,-AS-ODN (n=24), animals were euthanized, and membranes were prepared from the renal cortex of the left kidneys as previously described (Baker and Pitha, 1982). For saturation studies, 100 μg membrane protein was incubated in triplicate with 6 concentrations of [ 125 ](-)iodocyanopindolol (ICYP, NEN Life Science, 6.25 to 100 pmol/L) in a total volume of 250 μL containing 50 mmol/L Tris-HCI (pH 7.4) and 5 mmol/L MgCl 2 at 36°C for 60 min. The nonspecific and β 2 - adrenergic receptor binding levels were determined in the presence of 1 μmol/L (±)- alprenolol and 150 nmol/L CGP20712A (RBI), respectively. Then the reaction mixture was passed through a Whatman GF/B glass fiber filter with a Brandel harvester, and the bound radioactivity was counted for 1 min. 5.2.1.5 TISSUE PREPARATION AND QUANTITATIVE AUTORADIOGRAPHY Four days after injection of 0.5 mg/kg β r AS-ODN (n=6) or saline (n=6), rats were euthanized, and the right kidneys were removed and frozen in dry ice. Sagittal sections of kidney (20 μm) were cut on a cryostat (Microm) at " 20°C and mounted on microscope slides. Every seventh slide was stained with hematoxylin and eosin for histology. Receptor autoradiography was performed as described (Matthews et al, 1994) with 100 pmol/L ICYP at 25°C for 150 min. in the presence of 1 μmol/L (-)propranolol, 100 nmol/L ICI 118,551 (β 2 -selective antagonist), or 100 nmol/L CGP 20712A (β r selective antagonist) to distinguish nonspecific, β l5 and β 2 -bindings. The images were quantified with a computerized image analysis system (MCID, Imaging Research) and normalized with 125 I standards. Nonspecific binding was <10% of total binding. 5.2.1.6 REVERSE TRANSCRIPTION-POLYMERASE CHAIN REACTION AND SOUTHERN BLOTTING At different time points after the single injection of β r AS-ODN or inverted ODN, rats were euthanized, and the renal cortex was dissected from the left kidneys, immediately dipped into RNA later tissue storage buffer (Ambion), and stored at " 20°C. Total RNA was extracted with RNAwiz reagent (Ambion) and quantified by spectrophotometer. RNA samples from 4 to 5 rats from each time point were pooled. RNA (5 μg) was digested by DNase I and reverse-transcribed by Superscript reverse transcriptase (GIBCO BRL) at 42°C for 50 min. and 1/20 of the reverse transcription (RT) product was used to run a polymerase chain reaction (PCR) for 20 cycles. PCR primers for β r AR were 5'-CTCCGAAGCTCGGCATGG-3' (SEQ ID NO: 199) (forward) and 5'-GCACGTCTACCGAAGTCCAGA-3' (SEQ ID NO:200) (reverse) and yielded products of 432 bp, which spanned the AUG start codon. Primers for preprorenin were 5'-AGGCAGTGACCCTCAACATTACCAG-3' (SEQ ID NO:201) (forward) and 5'-CCAGTATGCACAGGTCATCGTTCCT-3' (SEQ ID NO:202) (reverse) and yielded products of 362 bp. Primers for GAPDH were 5*-ATCAAATGGGGTGATGCTGGTGCTG-3* (SEQ ID NO:203) (forward) and 5'-CAGGTTTCTCCAGGCGGCATGTCAG-3' (SEQ ID NO:204) (reverse) and yielded products of 505 bp (Jo et al, 1996). RT-PCR products were subjected to Southern blotting, hybridized with psoralen-biotin-labeled cDNA probes, and detected with nonisotopic kits (Ambion). After the membranes had been exposed to x-ray films, the intensity of βj-AR and preprorenin mRNAs was quantified by densitometry and normalized with GAPDH mRNA levels. The studies were repeated at least twice. 5.2.1.7 PRA AND PLASMA ANG II LEVELS PRA was determined with an angiotensin I ( 1 5 I) radioimmunoassay kit (DuPont). Plasma Ang II levels were measured by radioimmunoassay as previously described (Phillips and Kimura, 1988). 5.2.1.8 STATISTICAL ANALYSIS Values were expressed as mean ± SEM. Differences were considered statistically significant at a value of .PO.05. One-way repeated ANOVA and Tukey's test were used to compare blood pressure before and after AS-ODN treatment. Unpaired t test was used to compare B ma) PRA, and plasma Ang II levels in 2 groups. 5.2.2 RESULTS 5.2.2.1 OPTIMIZATION OF β r AS-ODN DELIVERY BY CATIONIC LIPOSOMES Systemic delivery of AS-ODN was optimized with the commercially available cationic lipid DOTAP mixed with neutral lipid DOPE. Previous studies reported that a charge ratio of DOTAP:DNA of «2.0 achieved the best gene delivery in vivo and in vitro (Yang et al, 1997 and Templeton et al, 1997). Therefore, 5 charge ratios of DOTAP:ODN were tested ranging from 0 to 3.5 to deliver 0.5 mg/kg β r AS-ODN intravenously. It was noticed that different batches of liposome mixture varied slightly in structure and particle size, which may influence the delivery efficiency. FIG. 7 shows the effect of different Hposome:ODN charge ratios on blood pressure of SHR (n=6 for each ratio) in a representative experiment. βi-AS-ODN alone, i.e. at ratio 0, did not change SBP, whereas ratio 0.5 significantly reduced SBP by up to 33 mm Hg for 7 to 8 days. When the ratio was increased, the duration of the hypotensive impact was drastically prolonged to 20 days at ratio 1.5 and 33 days at ratio 2.5 and 3.5, varying with liposome preparations. But the maximum drop in SBP was greater at ratio 1.5 and 2.5 («35 mm Hg) than at ratio 3.5 (»25 mm Hg) (Table 2). Accordingly, the optimal charge ratio of DOTAP: ODN was determined to be 2.5. In the subsequent experiments, SHR (n=24) injected with 0.5 mg/kg β j -AS-ODN with liposomes at a charge ratio of 2.0 were analyzed for the time course of changes in SBP, receptor levels, and peripheral RAS. TABLE 4 RANGES OF AMPLITUDE AND DURATION OF REDUCTION IN BLOOD PRESSURE OF SHR AFTER A SINGLE INTRAVENOUS INJECTION OF 0.5 MG/KG β r AS-ODN DELIVERED IN DIFFERENT CHARGE RATIOS OF LIPOSOME/ODN Charge Ratio Maximum Reduction Range of Duration, d of Liposome/ODN in Blood Pressure, Reduction, (Range) mm Hg mm Hg 0 2 ΦΦΦ *** 0.5 35-38 24-38 7-8 1.5 28-35 18-35 18-20 2.5 30-34 20-34 20-33 3.5 20-24 15-24 20-33 5.2.2.2 EFFECTS OF β r AS-ODN ON β-ADRENERGic RECEPTORS IN RENAL CORTEX Scatchard analysis of β-AR binding in renal cortex (FIG. 8A, FIG. 8B and FIG. 8C) indicated that β r AR was the major subtype in the control rats, composing 70% of total β- AR. After β r AS-ODN injection, the B max of β r ARs was diminished significantly, by 35% on day 4 (PO.05), 29% on day 10 (PO.05), and 23%) on day 18, and completely restored on day 40. βi-AR reduction in kidney coincided with that in heart, and both were accompanied by a significant drop in SBP (PO.01) (FIG. 8A). In contrast, the β 2 -AR level was not affected (FIG. 8B), nor was the affinity of either subtype. Inverted ODN had no effect on either subtype (FIG. 8C). Kidney slices from the same rats were subject to quantitative autoradiography to display the structural distribution of β-ARs. β r Subtype composed «60% of the β-AR levels, which was localized predominantly in the renal cortex and the outer band of the medulla. β 2 - Subtype was more diffusely distributed in the kidney at a lower level. This result was consistent with previous reports (Summers et al, 1985). Four days after β r AS-ODN treatment, the overall density of βi-subtype in kidney was significantly reduced from 23.5 ± 2.1 to 15.4 ± 3.3 fmol/mg (PO.05). The diminution in renal cortex was particularly conspicuous because of the higher basal level. As expected, the distribution and concentration of β 2 -subtype remained unchanged in accord with binding results. This further confirms the specificity of the inhibitory effect of β r AS-ODN on β r subtype. In an effort to demonstrate whether βi-AS-ODN decreases the mRNA level of β j -AR by inducing RNase H digestion, a pair of primers flanking the AUG start codon where β,- AS-ODN was targeted was used to run a semiquantatitative RT-PCR™ for 20 cycles, followed by Southern blotting, β j -AS-ODN did not reduce the level of steady-state β j -AR mRNA in renal cortex, indicating that the inhibition of β r AR expression was not at the transcriptional level. 5.2.2.3 EFFECT OF β x -AS-ODN ON PERIPHERAL RAS RT-PCR™ revealed that the preprorenin mRNA level in renal cortex was transiently decreased to 62% of control 4 days after β r AS-ODN injection. It was completely reversed , by day 18 (FIG. 9A). Conversely, PRA and plasma Ang II levels showed different patterns of reduction, which were significantly decreased on day 10 and day 18 (PO.01) but not on day 4. Thus, PRA and Ang II seemed to have as delayed action relative to the reduction in renin mRNA (FIG. 9B). 5.2.3 SUMMARY Because β j -adrenergic receptors are also involved in renin expression and secretion from the kidney, the present study was designed to evaluate the effect of βi-AS-ODN on peripheral RAS and its contribution to the reduction in blood pressure. In addition, a significant improvement of hypotensive action up to 33 days was achieved by optimizing the delivery of β r AS-ODN with cationic liposomes. β-blockers have been used to treat hypertension for 3 decades. The reasons for their antihypertensive effects remain largely unclear, but the inhibition of renin release is regarded as a primary mechanism. Many β-blockers can reduce PRA in patients and experimental animals (Blumenfeld et al, 1999 and Holmer et al, 1994). They are found to be more effective in patients with higher renin profiles (Buhler, 1988). In this study, it was found that βi-AS-ODN effectively decreased PRA and Ang II in the long term. But the decrease in PRA and Ang II did not occur until ∞IO days after β,- AS -ODN injection, in contrast to the rapid drop in cardiac output 2 days after injection. Thus, it appears that the effects of β r AS- ODN on the kidney renin and the circulating RAS are more delayed than cardiac action. Suppression of cardiac output may account for the early phase of the antihypertensive effect of β j -AS-ODN, whereas the inhibition of renin-angiotensin activity acts as the secondary mechanism underlying the sustained reduction of blood pressure in SHR. Receptor binding assay showed that β r AS-ODN reduced the βj-AR levels in renal cortex by 30% for 18 days. This is consistent with the decrease of β,-AR in heart ventricles in magnitude and time course. This suggests that β r AS-ODN delivered by cationic liposomes is rapidly transported to peripheral organs after intravenous injection and effectively taken up into heart and kidney cells to a comparable extent. Several mechanisms have been proposed for the AS-ODN inhibition of the expression of target proteins. One involves the decrease in mRNA levels resulting from RNase H digestion of the RNA strand of the RNA-DNA duplex (Phillips et al, 1996 and Phillips et al, 1997). To test this hypothesis, a pair of primers that flanked the AUG start codon of βi-AR mRNA were designed where AS-ODN bound to perform semiquantitative RT-PCR™. As shown in the Results, there was no reduction in the RT-PCR™ products, indicating the absence of RNase H action. Therefore, the inhibition of βi-AR expression probably occurs in post- transcriptional steps. By decreasing β r AR levels in kidney, βj-AS-ODN significantly reduced PRA and the subsequent plasma Ang II levels. This is unlikely to be through the inhibition of renin expression, however, because there is no long-term diminution of renin mRNA levels. Instead, βj-AS-ODN may exert its inhibitory impact on renin secretion or the conversion of inactive renin to active renin. This hypothesis is consistent with the observation that β- adrenergic stimulation of renin expression had a time course different from that of renin secretion (Holmer et al, 1997 and Chen et al, 1993). Furthermore, β-blockers have been shown to reduce prorenin processing to active renin without changing total renin (prorenin + PRA) levels in plasma (Blumenfeld et al, 1999). Efficient gene delivery is vital to the therapeutic application of AS-ODN in vivo. Among nonviral vectors, cationic liposomes are the most widely used. They are safe, nonimmunogenic, and east to produce on a large scale. However relatively low transfection efficiency has been obtained after intravenous administration, mainly because of the inactivation of cationic liposome by serum. It was recently shown that increasing the charge ratio (+) of liposome to DNA and inducing the maturation of Hposome-DNA complex by prolonging incubation time can overcome this problem (Yang et al, 1997; 1998). The optimal charge ratio of DOTAP:DNA was demonstrated to be «2 (Yang et al, 1991 and Templeton et αl., 1997). Thus, 5 charge ratios were tested ranging from 0 to 3.5 to optimize the AS-ODN delivery. As shown in the results, increasing the charge ratio not only improved the delivery efficiency but also prolonged the duration of β j -AS-ODN action. The best antihypertensive result (-35 mm Hg for 33 days) was consistently achieved at ratio 2.5. In summary, βj-AS-ODN delivered with cationic liposomes at a single intravenous injection achieves a marked and sustained hypotensive effect (30 to 35 mm Hg for 33 days) in SHR. The β r AS-ODN is clearly longer lasting than any current drug, does not inhibit β 2 - adrenergic receptors or cross the blood-brain barrier, and has negligible effect on heart rate. Therefore, the antisense is likely to have fewer side effects than currently used β-blockers. Inhibition of cardiac contractility initially followed by reduced renin release is an important mechanism contributing to its antihypertensive effects. 5.3 EXAMPLE 3 ~ TREATMENT OF HYPERTENSION USING ANTISENSE COMPOUNDS 5.3.1 MATERIALS AND METHODS 5.3.1.1 ANTISENSE DESIGN AND ADMINISTRATION AS-ODN and inverted-ODN control were 15 mer and targeted to the AUG start codon of rat βi-adrenoceptor mRNA (Machida et α/., 1990). The sequence of AS-ODN was 5'-CCGCGCCCATGCCGA-3' (SEQ ID NO:l), and the sequence of the inverted-ODN was 5'-AGCCGTACCCGCGCC-3' (SEQ ID NO:138). This AS-ODN was chosen from six AS candidates targeted to different regions of βi-adrenoceptor mRNA, based on the intensity of cardiac β j -AR inhibition and reduction of blood pressure in SHR. These oligonucleotides were modified by backbone phosphorothioation. ODNs delivered with cationic liposomes were injected into tongue vein. 5.3.1.2 PREPARATION OF LIPOSOMES AND ODN/LIPOSOME COMPLEX The cationic lipid l,2-bis(oleoyloxy)-3-(trimethylammonio)propane (DOTAP) was mixed with a helper lipid L-α dioleoyl phosphatidylethanolamine (DOPE, Avanti Polar Lipids) at 1:1 mole ratio, briefly sonicated and stored at 4°C until use. The average diameter of liposome is 200-350 nm (Tang and Hughes, 1998). ODN/liposome complex was prepared on the day of use by mixing desired amounts of ODNs with DOTAP/DOPE to the final DNA concentration of 300 μg/ml in 5% (wt./vol.) dextrose in water and incubating at room temperature for 60 min. Two DNA/lipid mole ratios, i.e., 1:0.5 and 1:2.5, were used in each study. 5.3.1.3 ANIMAL SURGERY Adult male SHRs (250-350 g, Harlan) were kept in cages in a room with a 12-hr light-dark cycle. Animals were fed standard laboratory rat chow and tap water ad libitum. 5.3.1.4 TELEMETRIC SENSORIMPLANTATION Before implantation, the zero of each radiotransmitter (TA11PA-C40, Data Sciences) was verified to be < 4 mm Hg. SHR were anesthetized with 100 mg/kg ketamine and 15 mg/kg xylazine and a midline abdominal incision was made. A fluid-filled catheter was then inserted into the right femoral artery and the tip of the catheter was in the abdominal aorta caudal to the renal arteries. The implanted rats were allowed to recover for one week. 5.3.1.5 JUGULAR VEIN CANNULATION One week after telemetric implantation, rats were anesthetized and a curved catheter made of PE 50 and vinyl tubing was inserted into the external branch of the jugular vein. The tubing was led under the skin of the neck and exposed on the back to allow for drug infusion. Rats were allowed to recover for 24 hr before experimentation. The catheters were flushed with 100 U heparin every day to prevent clogging. 5.3.1.6 MEMBRANE PREPARATION AND β-AR BINDING ASSAY Four days after intravenous injection of saline (n=6) or 1 mg/kg inverted ODN (n=6), or 2, 4, 10, 18 days after injection of 1 mg/kg β r AS-ODN (n=24), animals were sacrificed and membranes were prepared from heart ventricles as previously described (Baker and Pitha, 1982). For saturation studies, 100 μg membrane protein was incubated in triplicate with six concentrations of 125 I-(-)iodocyanopindolol (I-CYP, NEN Life Science, 6.25-100 pM) in a total volume of 250 μl containing 50 mM Tris-HCI (pH 7.4), 5 mM MgCl 2 at 36°C for 60 min. The nonspecific and β 2 -adrenoceptor binding levels were determined in the presence of 1 μM (±)-alprenolol and 150 nM CGP20712A (RBI), respectively. Then the reaction mixture was passed through Whatman GF/B glass fiber filter using Brandel harvester and the bound radioactivity was counted for one min. 5.3.1.7 TISSUE PREPARATION AND QUANTITATIVE AUTORADIOGRAPHY Four days after injection of 1 mg/kg β r AS-ODN (n=6) or saline (n=6), rats were sacrificed and tissues were removed and frozen in dry ice. Coronal sections of brain, horizontal sections of heart and sagittal sections of kidney (20 μm) were cut on a cryostat (Microm) at -20°C and mounted on microscope slides. Every seventh slide was stained with haematoxylin and eosin for histology. Tissue sections were preincubated in Krebs buffer (NaCl 118.4 mM, KCl 4.7 mM, MgSO 4 1.2 mM, CaCl 2 1.27 mM, NaH 2 PO 4 10.0 mM, pH 7.1) containing 0.1 mM guanosine triphosphate (GTP), 0.1 mM ascorbic acid and 10 μM phenylmethylsulfonylfluoride (PMSF) for 30 min at 25°C. Sections were then incubated in Krebs buffer containing 0.1 mM ascorbic acid and 10 μM PMSF with 100 pM I-CYP at 25°C for 150 min, in the presence of 1 μM (-)propranolol, 100 nM ICI118,551 (β 2 -selective antagonist) or 100 nM CGP20712A (βi-selective antagonist) to distinguish non-specific, β r and β 2 -bindings. Labeled sections were rinsed in the same buffer, followed by two 15-min washes at 37°C in the buffer and rinsed in distilled water at 25°C (Matthews et al, 1994). Dried sections were then exposed to X-ray films (Kodak Biomax-MR). The images were quantitated with a computerized image analysis system (MCID, Imaging Research) and normalized using 125 I-standards. Non-specific binding was less than 10% of total binding. 5.3.1.8 DETERMINATION OF EFFECTS OF β x -AS AND ATENOLOL ON CARDIOVASCULAR PARAMETERS IN RESPONSE TO β-SτiMULATi0N 5.3.1.8.1 LANGENDORFF HEART PERFUSION Forty-eight hr after injection of 1 mg/kg β r AS-ODN (n=9) or inverted-ODN (n=6), SHR were anesthetized and sacrificed. Hearts were quickly removed and perfused via the aorta with oxygenated Krebs buffer (118 mM NaCl, 18.75 mM NaHCO 3 , 1.2 mM KH 2 PO 4 , 4.7 mM KCl, 1.2 mM MgSO 4 , 1.25 mM CaCl 2 , 11.1 mM Glucose, 0.01 mM EDTA) at a constant flow of 7.0 ml/min at 36°C. Coronary perfusion pressure (CPP) was measured via a catheter placed proximal to the aorta and connected to a pressure transducer (Gould Statham P23ID). A latex balloon filled with water and connected to the pressure transducer was inserted into the left ventricle through the left atrium to measure left ventricular end-diastolic pressure (LVEDP), left ventricular systolic pressure (LVSP), and developed left ventricular pressure (dLVP) (dLVP = LVSP - LVEDP). LVEDP during equilibration was set at 5 to 7 mmHg. CPP, LVEDP and LVSP were continuously recorded on a 4-channel recorder (Astro-Med). After baselines for dLVP and heart rate (HR) were stable for 5 min, isoproterenol (ISO, non-specific β-agonist) was given at 0.01, 0.025, 0.05, 0.12 μM at 10- min intervals so as to avoid the effect of tachyphylaxis. 5.3.1.8.2 TELEMETRIC MONITORING OF LIVE ANIMALS The effects of β r AS-ODN and atenolol on cardiac dP/dt^, HR and systolic blood pressure (SBP) were compared in the same group of SHR (n=4). Two days after catheterization of jugular vein, control values were taken and 1 mg/kg βj-AS-ODN was injected. Forty-eight hr later, rats were tested for the effect of βj-AS-ODN. The rats were allowed to recover until all the cardiovascular parameters returned to control values. Then 1 mg/kg atenolol (β j -selective antagonist) was injected and rats were tested 30 min later. For βi-stimulation, SHR were infused with dobutamine (βi-selective agonist) through jugular vein catheter at 5, 10, 20, 40 μg/kg/min. Each dose was given for 5 min continuously and at 1-hr intervals until all cardiovascular parameters returned to baseline so as to avoid the effect of tachyphylaxis. BP and HR were sampled every min. dP/dt max was calculated from the slope of the rising pulse pressure curve and determined every min. The difference between values at each dose and baseline was denoted as Δ. 5.3.1.9 BLOOD PRESSURE MONITORING 5.3.1.9.1 TELEMETRY Each rat cage was placed on a receiver (RLA1020, Data Sciences) for measurement of cardiovascular parameters. Data were collected with a computer-based data acquisition program (Dataquest LabPRO3.0; Data Sciences). BP and HR were measured every 10 min and averaged every 1 to 24 hr. Before treatment, SHR were monitored for a week to get a stable baseline. 5.3.1.9.2 TAILCUFF Rats were warmed for 20-30 min in cages on heating pads. The temperature was controlled at 35-37°C. Then rats were placed in a plastic restrainer kept at 37°C. A pneumatic pulse sensor was attached to the tail. After cuff inflation, SBP was determined as the first pulsatile oscillation on the descending side of pressure curve. HR was determined by manual counting of pulse numbers per unit time. BP and HR were recorded by a Narco physiograph. Data values of each rat were taken as an average of at least four stable readings. Baseline was determined by averaging three days of measurements before antisense administration. 5.3.1.10 STATISTIC ANALYSIS Values were expressed as mean ± SEM. Difference was considered statistically significant at PO.05. Unpaired t-test was used to compare B max , dLVP and BP in two groups. One way repeated ANOVA and Tukey test were used to compare ΔdP/dt and ΔHR upon dobutamine infusion in different groups. Pearson product moment correlation was used to assess the relationship between βi-adrenoceptor B max and dLVP. 5.3.2 RESULTS 5.3.2.1 EFFECT ON CARDIAC β-ADRENOCEPTOR DENSITY A single intravenous injection of 1 mg/kg β r AS-ODN delivered with cationic liposomes at a 1:2.5 mole ratio significantly reduced the β r adrenoceptor densities in the SHR hearts for 18 days (PO.01). The drop was at its maximum of 47% on day 4, 33% on day 10, and maintained at 29% on day 18. In contrast, there was no significant change in the B max of β 2 -adrenoceptors. K D of both subtypes remained unaltered (Table 5). Consequently, the βι/β 2 subtype ratio in the ventricles was diminished from -70/30 to -50/50 by β r AS- ODN. Inverted-ODN had no effect on either subtype.

First, isolated hearts were perfused with incrementing doses of ISO, which enhanced heart rate and contractility via activating β-adrenoceptors. The dLVP-ISO dose-response curve, which reflected the positive inotropic effect of ISO, was significantly shifted down by βi-AS-ODN (PO.02). Heart rate was not significantly decreased. In vivo test was performed in conscious SHR monitored by radiotelemetry. β j -AS- ODN significantly (PO.02) dampened the increase in dP/dt^ in the face of dobutamine (β r selective agonist). The change in heart rate was not significantly reduced, which echoed the results in isolated, perfused hearts. On the other hand, the response of blood pressure to dobutamine was biphasic. Dobutamine elevated SBP by 5-8 mmHg at low infusion speed and reduced SPB at higher speed. This is probably due to the partial β 2 -argonistic activity of dobutamine at high doses and the consequent vasodilatory effect on blood pressure. Relative to β j -AS-ODN, 1 mg/kg atenolol produced a more profound decline in ΔdP/dt max and ΔHR during a 5-hr period of time after injection. Moreover, it reduced the resting dP/dt^ (2450±295 mmHg/sec versus control 2937±277 mmHg/sec) and caused bradycardia (295±12 bpm versus control 365±8 bpm) (PO.05), while β AS did not change resting contractility (2922±249 mmHg/sec) or heart rate (365±12 bpm). But the effects of atenolol on ΔdP/dt^ and ΔHR were transient. Within 24 hr after atenolol administration, the inotropic and chronotropic effects of dobutamine had returned to control level. 5.3.2.3 EFFECT ON BLOOD PRESSURE OF SHR The effects of single injection of 1 mg/kg βj-AS-ODN on blood pressure of SHR measured by tailcuff method were observed. AS-ODN was delivered with cationic liposome at different mole ratios of DNA/lipid, i.e., 1:0.5 and 1:2.5. β r AS-ODN delivered with liposomes at 1:0.5 ratio diminished SBP for 8 days. The maximum drop was 38±5 mmHg. When the mole ratio was increased to 1:2.5, this hypotensive effect was drastically prolonged to 20 days. No effect was seen with inverted-ODN. In order to compare the effects of β r AS-ODN and atenolol, radiotelemetry was used to monitor blood pressure and heart rate on a regular basis. One mg/kg β r AS-ODN delivered with liposomes at a 1:0.5 ratio produced a maximum drop of 15 mmHg in mean blood pressure. The antihypertensive effect lasted for 8 days, which was consistent with the results measured with tailcuff. Heart rate was not significantly altered. In contrast to AS- ODN, although the onset of hypotensive effect caused by 1 mg/kg atenolol occurred as early as 20 min after injection, it lasted for only 10 hr. In addition, atenolol caused considerable bradycardia up to an average of -75 bpm. 5.3.2.4 EFFECT ON β-ADRENOCEPTOR DISTRIBUTION IN BRAIN, HEART AND KIDNEY Quantitative autoradiography of 6-18 tissue slices in brain, heart and kidney was analyzed four days after intravenous β j -AS-ODN administration. No changes in the distribution of β-adrenoceptors in forebrain and brainstem regions were detected. This indicated the absence of antisense effect on the β-adrenoceptor expression in CNS. However, β r AS-ODN significantly (PO.05) reduced β r adrenoceptor densities in cardiac ventricles (from 30.2+2.1 to 20.6+2.5 fmol/mg) and renal cortex (26.4+3.1 to 17.4+3.3 ' fmol/mg). This was consistent with the binding results. β 2 -adrenoceptors were not affected in any tissues. 5.3.3 SUMMARY This example demonstrates the effects of βi -AS-ODN compositions on high blood pressure in a model of hypertension as compared to using a traditional β-blocker modality. βi-AS-ODNs knocked down βi-adrenergic activity, resulting in long-term attenuation of blood pressure. The results indicated that β, -AS-ODN reduced β r adrenoceptor density and cardiac contractility following β j -stimulation in vitro and in vivo and lowered high blood pressure of SHR. These findings are consistent with the hypothesis that βι~AS, through the inhibition of β,-adrenoceptor expression, is able to render heart, kidney and other tissues less sensitive to sympathetic activation, which is a major contributing factor in high blood pressure. A single injection of β j -AS-ODN effectively decreased the cardiac β r adrenoceptor density, which was accompanied by diminished ventricular contractility and cardiac output in response to β-stimulation. The antihypertensive effect in SHR was up to a 38-mmHg reduction lasting as long as 20 days. Treatment of β r AS-ODN reduced cardiac βj-adrenoceptor density by -50% in four days. There is considerable variation reported in the literature on the half-life of β- adrenoceptors (Baker and Pitha, 1982; Neve and Molinoff, 1986; Winter et al, 1988). From the results with the AS-ODN inhibition, it appears that the half-life of cardiac β r adrenoceptor is approximately 2-4 days to allow for 50% reduction of β-adrenoceptor density within 4 days. Both tailcuff and telemetry measures of blood pressure showed a significant drop after antisense treatment. SHR responded to βi-AS-ODN to a greater degree of hypotension when subjected to tailcuff versus telemetry. In addition, the baseline measured with tailcuff was consistently higher than that with telemetry by 20-30 mmHg in the same rats. Bazil et al. (1993) reported a similar phenomenon. They compared the cardiovascular parameters recorded by telemetry, tailcuff and arterial catheter and observed a more sensitive hypotensive effect of captopril with tailcuff. Tailcuff measurement of blood pressure involves warming and restraint of rats. It is conceivable that βi-AS, through the suppression of sympathetic activity, can decrease blood pressure of animals under stress more effectively. Cationic liposomes are effective vehicles for gene delivery. It has been shown that liposome entrapment not only improves the cellular uptake of DNA, but also protects DNA from degradation and extends its circulation time (Allen, 1997; Liu et al, 1997). Numerous factors influence the efficiency of cationic liposome-mediated intravenous gene delivery, such as DNA lipid ratio, selection of lipids and preparation procedure (Liu et al, 1997; Yang and Huang, 1998). A widely used lipid formula DOTAP/DOPE was used to deliver β r AS- ODN at four mole ratios (1:0.5, 1:1.5, 1:2.5, and 1:3.5). The optimal ratio 1:2.5 was determined based on the duration and magnitude of the antihypertensive effects. A profound and prolonged fall in blood pressure of 38 mmHg up to 20 days was achieved at this ratio, which followed the reduction in βi-adrenoceptor binding to a maximum of 47% at day 4, 33% at day 10, and 29% at day 18. This implies that β r AS-ODN effectively inhibits the functionally active receptors involved in the blood pressure. The blood-brain barrier formed by capillary endothelia is only permeable to small lipophilic molecules with molecular weight <600 Da (Padridge, 1998). Owing to their high hydrophilicity, ODNs undergo negligible transport through blood-brain barrier and have very limited access to CNS (Agrawal et al, 1991). The cellular and organ distributions of DNA/liposome complexes with fluorescent labeling were previously studied in mice after intravenous injection and the results indicated that the complexes were primarily taken up by capillary endothelial cells in most of the peripheral organs including lung, heart, kidney and spleen, but absent in the brain (McLean et al, 1991). Although the brain retention of liposomes after peripheral administration was observed in some cases, it is due to entrapment within the brain microvasculature (Schackert et al, 1989). In this study, autoradiography in brain revealed no detectable changes in the expression and distribution of β-adrenoceptors after intravenous β r AS-ODN injection. This provided further evidence that an antisense modality does not produce CNS effects. High specificity based on gene sequence has made antisense an increasingly useful tool in numerous studies and clinical trials. Its success is manifested by the recent approval of the first antisense drug Vitrovene by FDA. In the present study, βj-AS-ODN inhibited β AR expression without changing β 2 -adrenoceptors, demonstrating a specificity of the β AS- ODN selected sequences. In patients with chronic heart failure, the severity of the disease closely relates to the decrease in cardiac β-AR density and functional responsiveness (Brown et al, 1992). In SHR treated with β r AS~ODN, a marked attenuation of the βi-adrenoceptor-mediated positive inotropic response was observed in vitro and in vivo, concurrent with the diminished cardiac βi-AR level. Therefore, these results indicated a positive correlation between cardiac βi-AR number and functional sensitivity (correlation coefficiency > 0.90, PO.01). Despite the large decrease in blood pressure, no reflex tachycardia was observed after antisense treatment. However, the suppressive effect of β r AS-ODN on heart rate was less significant than its negative inotropic response. The reason for this is still under investigation. Several possibilities can be considered. First, β,-AS-ODN did not affect β 2 - adrenoceptors, which played an important role in the regulation of heart rate (Kaumann, 1986; Rodefeld et αl., 1996), while not involved in the cardiac contraction. Second, antisense inhibition of βi-AR expression is gradual and to a lesser extent than β-blockers. It is also possible that β r ARs may have a larger reserve for controlling heart rate than contractility. Finally, evidence suggests that cardiomyocytes preferentially take up AS-ODN while pacemaker cells are less efficient. The cardiovascular effects of β r AS-ODN were compared with a hydrophilic β r selective antagonist, atenolol. β r AS-ODN showed advantages over atenolol in reducing blood pressure and maintaining normal heart rate. Although the onset of βi-AS-ODN action was slower than atenolol, it lasted much longer, 20 days compared to less than 1 day with atenolol. Furthermore, βj -AS-ODN did not affect heart rate, while atenolol caused appreciable bradycardia. Bradycardia is a common complaint by patients taking this drug. Atenolol also reduced resting ventricular contractility and heart rate and thereby reduced resting cardiac output. β r AS-ODN is unlikely to alter resting cardiac performance. The results presented here suggest that β r AS-ODN offer a significant improvement over 5 currently used β-blockers, in both prolonged blood pressure reduction and absence of effects on β 2 -adrenoceptors and CNS. 5.4 EXAMPLE 4 - PROTECTION AGAINST MYOCARDIAL ISCHEMIA-REPERFUSION- INDUCED CARDIAC DYSFUNCTION BY ANTISENSE COMPOSITIONS l o DIRECTED AT β^AR MRNA Acute myocardial ischemia causes significant increase in plasma catecholamine levels, which leads to exacerbation of the ischemic myocardial injury (Waldenstrom et al, 1978; Rona, 1985). The worsening myocardial ischemia is an important factor in cardiac dysfunction. Acute myocardial ischemia is also characterized by increased sensitivity of 15 β]-ARs in the myocardium during acute ischemia (Strassere et al, 1990). β-ARs form the interface between the sympathetic nervous system and the cardiovascular system (Strassere et al, 1990; Mukherjee et al, 1979; Maisel et al, 1985. Importantly, β r AR subtype 1 (β r AR) is by far the predominant β-AR in myocardium (Minneman et al, 1995) and its activity and sensitivity are believed to regulate cardiac function via adenylyl cyclase activity (Mukherjee 0 et al, 1979; Thandroyen et al, 1986; Bδhm, 1995). Several studies have shown that density of βj-AR increases and the expression of βpAR mRNA is augmented in the myocardium after acute ischemia (Maisel et al, 1985; Karliner et al, 1989; Ihl-Vahl et al, 1995). Experimental and clinical results have also demonstrated that β-AR blockade, especially selective blockade of βi-AR, can protect myocardium against ischemic injury and cardiac 5 dysfunction (Schulz et al, 1995; Ablad et al, 1987; Lu et al, 1990), decrease infarct size (Schulz et al, 1995), and reduce the incidence of sudden cardiac death in patients with myocardial infarction (Yusuf et al, 1985). Although chemical β-AR blockers are commonly used in the treatment of ischemic heart disease, these agents often cause central nervous system side effects and β 2 -AR 30 antagonistic activity is associated with increase in peripheral vascular resistance. Development of antisense-oligodeoxynucleotides (AS-ODNs) against specific receptor mRNA is a novel approach to decrease the synthesis of receptor proteins (Phillips et al, 1996; Dachs et al, 1997). This approach has potential to be of therapeutic benefit in disease states characterized by upregulation of these receptors (Phillips et al, 1996; Dachs et al, 1997; Yang et al, 1998). A recent study indicated that AS-ODNs directed at angiotensin II type 1 receptors (AT j ) decrease the synthesis of ATj receptor protein and protects the ischemic rat heart from the adverse effects of ischemia (Yang et al, 1998). As demonstrated herein, a single intravenous injection of an antisense compositions directed against β r AR mRNA can reduce blood pressure in SHR for periods of at least 20 days (Zhang et al, 1999). In this example, the effect of AS-ODNs on lipid peroxidation was examined. Also examined were their effects on the expression of β r AR protein and mRNA in the myocardium after ischemia-reperfusion. 5.4.1 MATERIALS AND METHODS 5.4.1.1 ANTISENSE COMPOSITIONS AND LIPOSOMAL FORMULATIONS AS-ODNs and inverted-oligodeoxynucleotides (IN-ODNs) control were 15-mers and targeted to -5 to +10 of rat βi-AR mRNA encompassing the AUG start colon. The sequence of AS-ODNs was 5'-CCGCGCCCATGCCGA-3' (SEQ ID NO:l), and the corresponding IN- ODNs was 5'-AGCCGTACCCGCGCC-3' (SEQ ID NO:138) (Zhang et al, 1999). These ODNs were modified by backbone phosphorothioation and synthesized in the DNA Synthesis Core Laboratory of the University of Florida. Since cationic liposomes enhance the uptake of DNA by cells and also protect DNA from degradation and extend its circulation time, DOTAP/DOPE (mole:mole=l:l) liposomes were used to deliver the antisense compositions to host animals. The average diameter of liposomes was 200-300 nm. ODNs/liposomes complex was prepared on the day of use by mixing desired amount of ODNs with DOTAP/DOPE to final DNA concentration of 300 μg/ml in 5% (wt./wt.) dextrose in water and incubating at room temperature for 60 min (Yang et al, 1998; Zhang et al, 1999). 5.4.1.2 ANIMALS Male Sprague-Dawley rats weighing 200-250 g were injected intravenously with either AS-ODNs (n=7) or IN-ODNs (n=7) at a dose of 200 μg/rat 4 days before excising the hearts. DOTAP/ DOPE liposomes (700 μg/rat) were given along with ODNs. Parallel groups of rats were treated with saline (n=13), or the selective β r AR blocker atenolol 2 mg/kg (n=7) 6 hr before the hearts were excised. 5.4.1.3 ISOLATED PERFUSED HEART MODEL Four days after administration of AS-ODNs or IN-ODNs or 6 hr after administration of atenolol or saline, rats were anesthetized with sodium pentobarbital (40 mg/kg) intraperioneally. The hearts were excised rapidly and placed in ice-cold Kreb-Henseleit buffer (mmol/L: NaCl 118, KCl 4.7, KH 2 PO 4 1.2, MgSO 4 1.2, CaCl 2 1.25, NaHCO 3 25, and glucose 11, pH 7.4). Within one min, the hearts were transferred to an isolated perfusion apparatus and perfused via the aorta with oxygen-saturated (95% O 2 + 5% CO 2 ) Kreb- Henseleit buffer kept at 37°C with the use of a MasterFlex pump (model 7015-21, Cole- Palmer Instrument Co.) according to the modified Langendroff procedure (Yang et al, 1998; Neely and Rovetto, 1975). The heart was placed in a semi-closed circulating water- warmed (37°C) air chamber, paced atrially with a Medtronic 5320 pacemaker at a rate of 300 bpm, and perfused at a constant flow (5.5-6.0 ml/per min). Coronary perfusion pressure (CPP) was measured via a catheter placed just proximal to the aorta and connected to a Gould . Statham P23ID pressure transducer. A latex balloon filled with water and connected to a Gould Statham P23ID pressure transducer was inserted in the left ventricle through the left atrium to measure left ventricular end-diastolic pressure (LVEDP), left ventricular systolic pressure (LVSP), and developed left ventricular pressure (dLVP) (dLVP = LVSP - LVEDP). LVEDP during equilibration was set at 5 to 7 mmHg. All measurements were continuously recorded on a 4-channel record (Astro-Med). 5.4.1.4 MYOCARDIAL ISCHEMIA AND REPERFUSION Six hearts from saline-treated rats were continuously perfused with Kreb-Henseleit buffer for 80 min and served as sham control. Hearts from other rats, after 20 min of equilibration, were subjected to 30 min of ischemia followed by 30 min of reperfusion. After completion of the study, hearts were frozen in liquid-nitrogen for β r AR analysis by binding assay, βj-AR protein analyses by Western blot, βi-AR mRNA analysis by reverse transcription-polymerase chain reaction (RT-PCR™), and measurement of MDA. 5.4.1.5 DETERMINATION OF βi-AR DENSITY IN MYOCARDIUM Membrane protein was prepared from left ventricles as previously described (Baker and Pitha, 1982). For saturation studies, 100 μg membrane protein was incubated in triplicate with 125 I-(-)iodocyanopindolol (I-CYP, NEN Life Science, 6.25-100 pM) in a total volume of 250 μl containing 50 mM Tris-HCI (pH 7.4), 5 mM MgCl 2 at 36°C for 60 min. The nonspecific and β 2 -adrenoceptor binding were determined in the presence of 1 μM (±)- alprenolol and 150 mM CGP207ASA (RBI), respectively. Then the reaction mixture was passed through Whatman GF/B glass filter using Brandel harvester and the radioactivity was counted for one min. 5.4.1.6 QUANTIFICATION OF βi-AR PROTEIN EXPRESSION IN MYOCARDIUM Myocardial tissues were homogenized and lysed in boiling lysis buffer (1% SDS, 0.1% Triton X-100®, and 10 mmol/L Tris-HCI, pH 7.4) and centrifuged at 10,000 RPM for 30 minutes at 4°C. The lysate protein from myocardial tissues (20 μg/lane) was separated by 8% SDS-PAGE using a Bio-Rad Mini-Protean cell, transferred to nitrocellulose membrane (Amersham). After incubation in blocking solution (4% non-fat milk, Sigma), membranes were incubated with 1:1000 dilation primary antibody (polycolonal antibody to βi-AR, Santa Cruz Biotechnology) for overnight at 4°C. Membranes were washed and incubated with 1 :2000 dilution second antibody (Amersham) for one hr. The membranes were detected with the ECL system, as described previously (Yang et al, 1998; Li et al, 1999). 5.4.1.7 DETERMINATION OF β r AR MRNA Total RNA was isolated from rat myocardium with the single step acid-guanidinum thiocyanate-phenol-chloroform method and quantified (Chomcznski and Sacchi, 1987). One μg of total RNA was reverse transcribed with oligo-dT (Promega) and M-MLV reverse transcriptase (Promega) at 37°C for one hr. 1.5 μl of RT material was amplified with Taq DNA polymerase (Promega) using a primer pair specific to β j -AR: Forward primer: 5'-CTCCGAAGCTCGGCATGG-3' (SEQ ID NO:139); and Reverse primer: 5'-GCACGTCTACCGAAGTCCAGA-3' (SEQ ID NO: 140). PCR™ product was 432 base pairs. For PCR, 35 cycles were used at 95°C for one minute, 60°C for one minute, and 72°C for one min. The RT-PCR™ amplified samples were visualized on 1.8% agarose gels using ethidium bromide. A primer pair of rat GAPDH was used as control: Forward primer: 5'-ATCAAATGGGGTGCTGGTGCTG-3' (SEQ ID NO: 141); and Reverse primer: 5'-CAGGTTTCTCCAGGCGGCATGTCA-3' (SEQ ID NO: 142). For PCR™, 35 cycles were used at 95°C for one min, 60°C for one min, 72°C for one min. PCR™ product was 504 base pairs. Relative intensity of bands of interest were analyzed by NSF-300G Scanner (Microtek) (Yang et al, 1998; Li et al, 1999). 5.4.1.8 DETERMINATION OF MDA LEVELS IN MYOCARDIUM Malondialdehyde (MDA) levels in myocardium were measured in duplicate by a modification of the method of Ohkawa et al, (1979). Briefly, the ventricular tissues were homogenized. The assay mixture consisted of 0.1 ml of the tissue homogenate, 0.4 ml of 0.9%) NaCl, 0.5 ml of 3% sodium dodecylsulfate, 3 ml of TBA (thiobarbituric acid reagent, containing equal parts of 0.8%) aqueous thiobarbituric acid and acetic acid) and was heated for 75 min at 95°C. Thereafter, 1 ml cold 0.9% NaCl was added to the mixture, which was cooled and extracted with 5 ml «-butanol. After centrifugation at 3,000 rpm for 15 min, the butanol phase was assayed spectrophotornetrically at 532 nm. Tetramethoxypropane (in amounts of 0, 0.1, 0.2, 0.4, 0.8, 1.0 nmole) served as external standard. MDA levels in myocardium were expressed in μmol/g tissue. 5.4.1.9 DATA ANALYSIS Data was presented as mean ± SD. Statistical significance was determined in multiple comparisons among independent groups of data in which ANOVA and the Student- Newman-Keuls test indicated the presence of significant differences. A P value of <0.05 was considered statistically significant. 5.4.2 RESULTS 5.4.2.1 CARDIAC DYSFUNCTION DURING ISCHEMIA-REPERFUSION The basal values of CPP, LVSP, LVEDP, and dLVP were similar in all groups of rat hearts. In the control continuously buffer-perfused hearts observed for 80 min, there were only minimal (-5%) changes in the indexes of cardiac function. In the hearts from saline- treated rats, 30 min of ischemia followed by 30 min of reperfusion resulted in marked cardiac dysfunction, indicated by a significant increase in CPP and LVEDP, and a decrease in LVSP and dLVP (all PO.Ol, vs. pre-ischemia values). Treatment of rats with AS-ODNs markedly attenuated the ischemia-reperfusion- induced myocardial dysfunction, indicated by preservation of LVSP and dLVP and minimization of increase in LVEDP and CPP (all PO.Ol, vs. saline group). Treatment of rats with atenolol also reduced the increase in CPP and LVEDP induced by ischemia- reperfusion (all PO.05, vs. saline group, n=7), and modestly attenuated the ischemia- reperfusion-induced change in LVSP and dLVP (PO.05 vs. saline group, n=7). AS-ODN treatment was more effective than atenolol treatment in preserving dLVP after ischemia- reperfusion (PO.05). Treatment with IN-ODNs showed no effect on ischemia-reperfusion- induced myocardial dysfunction. 5.4.2.2 MDA LEVELS IN MYOCARDIUM MDA levels in myocardium increased significantly after ischemia-reperfusion (PO.05 vs. sham control hearts, n=6). Pretreatment of rats with AS-ODNs and atenolol attenuated the increase in MDA levels in the myocardium (both PO.05 versus saline pretreatment, n=7 each group). As expected, IN-ODNs did not affect MDA levels in myocardium. 5.4.2.3 CHANGE OF β x -AR DENSITY IN MYOCARDIUM AFTER ISCHEMIA- REPERFUSION Myocardium from sham control continuously perfused hearts continuously exhibited βi-AR and β 2 -AR (β r AR»β 2 -AR). After ischemia-reperfusion in the saline-treated rat hearts, there was a consistent increase in β j -AR density in myocardium (B max 28.7±5.4 vs. 19.6+1.7 fmol/mg in continuously perfused buffer-perfused rat hearts, PO.05, n=4), while there was no change in β 2 -AR density. Treatment of rats with AS-ODNs resulted in a decrease in β AR density in the ischemic-reperfused myocardium (B max 15.9±1.3 vs. 28.7±5.4 fmol/mg in saline-treated rat hearts, PO.05, n=4) while there was no change in β 2 - AR density. Treatment of rats with INV-ODNs or atenolol had no effect on β AR density in the ischemic-reperfused myocardium. 5.4.2.4 EXPRESS OF βi-AR PROTEIN AND MRNA IN MYOCARDIUM Western analysis of the control continuously perfused hearts showed a distinct βi-AR protein band of 41 kDa. Similar molecular weight band was observed in hearts from saline-, AS-ODNs-, IN-ODNs- and atenolol-treated rat hearts. The βi-AR protein band was very dense in the saline-treated rat hearts, including upregulation of the protein during ischemia- reperfusion. Treatment of rats with AS-ODNs abolished the ischemia-reperfusion-mediated increase in βi-AR protein expression. Notably, treatment of rats with IN-ODNs or atenolol had no effect on the density of β j -AR protein. Ischemia-reperfusion also resulted in an increase of mRNA for β r AR signal (adjusted for GAPDH signal) by myocardium of saline-treated rats, as determined by RT- PCR. Pretreatment of rats with AS-ODNs attenuated the increase of mRNA for βj-AR in myocardium, but mRNA level for βi-AR in the myocardium was not significantly affected by treatment of rats with IN-ODNs or atenolol. 5.4.3 SUMMARY The present example demonstrates the protective role of AS-ODNs directed at β r AR mRNA against cardiac dysfunction after a brief period of ischemia-reperfusion. The study compared the effects of pretreatment of rats with AS-ODNs directed at β j -AR mRNA or a selective βi-AR blocker atenolol in this process. This study showed that ischemia for 30 min followed by reperfusion for 30 min resulted in a significant cardiac dysfunction and lipid peroxidation in saline-treated rat hearts. Further, ischemia-reperfusion was associated with a marked upregulation of βi-AR density and protein and mRNA expression. Pretreatment of rats with atenolol preserved cardiac function, but did not affect the density of βi-AR and the expression of β j -AR protein and mRNA in the ischemic-reperfused myocardium. Pretreatment of rats with AS-ODNs directed at βi-AR mRNA provided almost total preservation of cardiac function and lipid peroxidation following ischemia-reperfusion. AS- ODN treatment also prevented the upregulation of βi-AR density, protein and mRNA expression in the ischemic-reperfused myocardium. The effects of AS-ODNs directed at β r AR mRNA on cardiac function were clearly superior to those of the commonly used β r AR blocker atenolol. The effects of AS-ODN on βi-AR protein and mRNA expression indicate that its beneficial effects are mediated by inhibition of both transcription and translation of βι-AR nιRNA. There is a generalized stimulation of the sympathetic nervous system during ischemia, perhaps a compensatory response designed to preserve cardiac dysfunction. Accordingly, catecholamine levels increase in both plasma and myocardium following myocardial ischemia (Rona, 1985; Richardt et al, 1994; Abrahamsson et al, 1983), but the increased catecholamine concentrations have the potential to contribute to increased excitability of myocardium resulting in arrhythmia (Strassere et al, 1990; Mukherjee et al, 1979; Maisel et al, 1985; Ohyanahi et al, 1988; Maisel et al, 1987). There is also increase in sensitivity of β j -AR during acute myocardial ischemia (Strassere et al, 1990). This coupled with increased circulating and myocardial catecholamine concentrations can exacerbate cardiac injury and dysfunction. It is generally accepted that activation of β-AR is the first element in the signal transduction chain mediating sympathetic stimulation of the heart. βj-ARs, the dominant β- AR subtype in the heart (Minneman et al, 1995; Guderman et al, 1995), regulate cardiac function by activating adenylyl cyclase activity (Strassere et al, 1990; Thandroyen et al, 1986; Bδhm, 1995). Several experimental studies have indicated an upregulation in β,-ARs, but not β 2 -ARs, during acute ischemia-reperfusion (Maisel et al, 1985; Karliner et al, 1989; Persad et al, 1998). Ihl-Vahl et al. (1995) conclusively demonstrated a rapid upregulation of β-AR mRNA during acute myocardial ischemia; this upregulation is subtype-selective with a specific increase mRNA level for βj-ARs, but not for β 2 -ARs. They also showed that the increase of βi-AR mRNA is ischemia time-dependent. Pretreatment of animals with β-AR blockers does not affect the ischemia-reperfusion- induced increase in βi-AR mRNA level. This was confirmed in the present study wherein treatment with atenolol did not affect either the β r AR density measured by binding assays or the augmented βi-AR protein and mRNA levels measured by Western analysis and RT-PCR, respectively. Other investigators have also shown that βi-AR blockers do not block the expression of β r AR protein or mRNA (Aarons and Molinoff, 1982; Heilbrunn et al, 1986; Aarons et al, 1980). In contrast, the present study clearly demonstrates that AS-ODNs directed at βi-AR mRNA block the up-regulation of βi-AR number, and protein and mRNA levels. The blockade of βi-AR at the transcriptional level may be the basis for the superior effect of the AS-ODN approach in the preservation of cardiac function after acute ischemia- reperfusion. Therapy with a single dose of AS-ODNs four days prior to removal of hearts prevented the increase in βi-AR protein, which implies sustained inhibitory effects of AS- ODNs at translational levels as well. A previous study in the SHR indeed demonstrated that AS-ODNs against βrAR mRNA decreases β r AR mRNA translation into protein in the hearts for at least up to 18 days (Zhang et al, 1999). Although chemical β-AR blockers are effective in the therapy of ischemic heart disease and are widely used in the short- and long-term management of patients with myocardial ischemia, these agents have several undesirable side-effects related to their effects on central nervous system, peripheral vascular resistance, and tracheo-bronchial tree. Even the selective β r AR blockers, such as atenolol, lose their cardio-selectivity at moderate doses. In addition, these agents need to be taken frequently, at least one daily, due to their short half-life. Furthermore, chemical β-AR blockers do not influence β-ARs at genomic level. Gene therapy, such as AS-ODNs directed at βi-AR mRNA, provides unique benefits. For example, the sequence specific AS-ODNs directed at βi-AR mRNA can significantly decrease ventricular βi-AR density by 30-50% even after 18 days in the rat after a single intravenous injection (Zhang et al, 1999). The AS-ODNs has no effect on β 2 -AR density. Concurrently, AS-ODN administration is associated with reduction in blood pressure with a 38-mnιHg maximum drop without causing bradycardia. Most importantly, there is no effect of AS-ODNs on the distribution of β-ARs in brain. These results demonstrate that a single intravenous injection of AS-ODNs can preserve cardiac dysfunction and protect myocardial injury from ischemia-reperfusion in the rat with specific effects on the expression of mRNA for βj-ARs in myocardium. Importantly, IN-ODNs, used as control for AS-ODNs, did not show any of these effects. In this study, ischemia-reperfusion-induced cardiac dysfunction was evaluated by the measurement of CPP, LVEDP, LVSP and dLVP. These indices of myocardial dysfunction have been used in several studies in the isolated heart model of global ischemia-reperfusion (Yang et al, 1998; Yang et al, 1993; Yang et al, 1997; Kokita et al, 1998; Ozden et al, 1998). Isolated rat, rabbit or guinea pig heart model provides an inexpensive and reproducible method to evaluate cardiac function and myocardial metabolic alterations during ischemia-reperfusion. This model has been used extensively to study regulation of variety of receptors and modulation of cardiac function by agents acting on different receptors (Lu et al, 1990; Yang et al, 1998; Neely and Rovetto, 1975; Baker and Pitha, 1982; Maisel et al, 1987; Yang et al, 1993; Yang et al, 1997; Kokita et al, 1998; Ozden et al, 1998). In the isolated beating heart, cardiac function can be assessed independent of the influence of circulating blood cells and hormones, which may be considered to provide an important advantage of this model. MDA, a lipid peroxidation product, has been widely accepted as an index to evaluate myocardial injury after ischemia-reperfusion (Kokita et al, 1998; Ozden et al, 1998). All these parameters were modified by the use of AS-ODNs in the present study. In summary, the present study is the first report on the amelioration of cardiac dysfunction and myocardial injury induced by ischemia-reperfusion in isolated rat heart with a single intravenous injection of AS-ODNs directed at βj-AR mRNA. This study also provides evidence that the AS-ODNs can block the augmented expression of mRNA for βi-AR in the ischemic myocardium. Lastly, the effects of AS-ODNs directed against β r AR mRNA appear to be superior to those of atenolol in the isolated rat heart model of ischemia-reperfusion. 5.5 EXAMPLE 5 - REDUCTION OF CARDIAC HYPERTROPHY IN ANIMAL MODELS Adult spontaneously hypertensive rats (300-350 g) were treated with βl -AS-ODNs for more than 2 months. The blood pressure was reduced by 20-30 mmHg persistently throughout the treatment period (FIG. 11). Control animals receiving saline or INV-ODNs had no change in blood pressure. At the end of a 2-month treatment, the hearts were dissected and weighed. Left ventricular hypertrophy was indicated by the ratio of left ventricle weight to body weight (LV/BW). βl -AS-ODNs significantly reduced left ventricular hypertrophy (PO.05), compared to controls (FIG. 11). 5.6 EXAMPLE 6 - ATTENUATION OF CARDIAC DYSFUNCTION AFTER MYOCARDIAL ISCHEMIA-REPERFUSION The protective effects of βl -AS-ODNs were tested in a rat model of myocardial ischemia-reperfusion. Five groups of SD rats were studied. Sham controls (n=6) were injected with saline and perfused continuously for 80 min without ischemia/reperfusion (I/R). In other groups, hearts were perfused for 20 min and subjected to global ischemia (30 min) followed by reperfusion (30 min). Saline + I/R (n=6) or atenolol + I/R (n=7) groups were injected i.v. with saline or 2 mg/kg atenolol 6 hr before the hearts were excised. AS-ODN + I/R (n=7) or INV-ODN + I/R (n=7) were injected i.v. with 1 mg/kg β r AS-ODN or INV- ODN 4 days before the I/R study was performed. Ischemia-reperfusion resulted in significant cardiac dysfunction, indicated by a significant increase in coronary perfusion pressure (CPP) and left ventricular end-diastolic pressure (LVEDP), and a decrease in developed left ventricular pressure (dLVP) (P O.01 vs. pre-ischemia values). Treatment with β j -AS-ODN markedly attenuated the ischemia-reperfusion induced ventricular abnormality, manifested by the preservation of dLVP and minimization of increase in CPP and LVEDP (P O.05 vs. saline group). Overall, AS-ODN treatment appeared to be equivalent to or even better than atenolol in these effects. AS-ODN restored dLVP to a greater extent than atenolol. INV-ODN showed no effect on ischemia-induced dysfunction and cannot be differentiated from saline group. Data on cardiac function parameters from these studies are summarized in FIG. 12. 5.7 EXAMPLE 7 - SAFETY PROFILE OF CHRONIC USE OF βi-AS-ODNs Safety profiles including liver transaminases, hematology, immune response and tissue pathology were investigated during tliree repeated injections of β r AS-ODNs for extended periods of time. The results indicated that long-term treatment with β r AS-ODNs is safe without causing toxic effects or immune reaction. 5.7.1 LIVER TRANSAMINASES Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are routinely used as a clinical index for liver function. Their levels increase substantially upon liver damage. SHR were treated with three repeated injections of β j -AS-ODN. Plasma concentrations of ALT and AST were measured after each injection, which revealed no significant difference between AS-ODN and control groups (FIG. 13). 5.7.2 HEMATOLOGY Hematological parameters were measured after three repeated injections of βi-AS- ODN. There was no change in total leukocyte count (WBC), platelet count, hematocrit and mean platelet volume (MPV) among three groups (Table 6).

C-reactive protein (CRP), a clinical index for immune reaction, was found negative in all animals. 5.7.4 TISSUE HISTOLOGY Heart, liver, spleen and kidney were subjected to pathological examination after three repeated injections of β j -AS-ODN for more than 2 months. No immunopathology or organ damage was found. 5.8 EXAMPLE 8 - DNA SEQUENCES OF KNOWN βj-AR GENES Particularly preferred antisense sequences for the practice of the present invention include those sequences that specifically bind at or near the region of the AUG translation initiation codon of the mRNA encoding a mammalian β r AR polypeptide. Thus, those complementary sequences that are centralized around the region of the mRNA corresponding immediately 5' of the AUG translation initiation codon are particularly preferred. Such sequences may be identified using a secondary structure analysis (e.g., the OLIGO computer program) to ensure that the oligonucleotides do not fold or self-anneal. The BLAST computer algorithm program may also be used to check the specificity of the chosen sequence. The ordinarily skilled artisan, having the benefits of the teachings of the present invention, can select other suitable antisense sequences using the OLIGO and BLAST programs in combination with the teachings of the subject invention to prepare both oligonucleotides that comprises at least 9 to about 35 contiguous nucleotides that are complementary to a portion of the mRNA encoding the open reading frames designated in each of the genes disclosed in SEQ ID NO: 187, SEQ ID NO: 188, SEQ ID NO: 189, SEQ ID NO:190, SEQ ID NO:191, SEQ ID NO:192, SEQ ID NO:193, or SEQ ID NO:194. For the preparation of full-length or substantially full-length antisense polynucleotides, the inventors contemplate the use of sequences corresponding essentially to the entire βi-AR-specific mRNA sequence produced from one or more of the following β r AR genes. For example, the open reading frame of the human βi-AR gene extends from nucleotide 87 to nucleotide 1520 of SEQ ID NO: 187. Therefore, a full-length antisense polynucleotide would consist of an approximately 1.43-knt (kilonucleotide) sequence that is complementary to the region of SEQ ID NO: 187 from about position 87 to about position 1520. In order for the complementary sequence to specifically bind to the native β j -AR- specific mRNA sequence, the polynucleotide need not be exactly the same size, or exactly the same sequence of the native mRNA. In fact, substantially full-length sequences or slightly larger-than full-length are contemplated by the inventors to be as useful in the inhibition of β r AR-specific mRNA translation in a host cell as full-length antisense polynucleotides. For example, the size of the complementary polynucleotide may vary (e.g., from about 95% to about 105% of the size of the ORF region of the particular βi-AR-specific sequence. Thus, for a 1.43-knt full-length mRNA, a sequence of from about 1.36-knt to about 1.43-knt would be considered "substantially full-length" while a sequence of from about 1.44-knt up to and including about 1.50-knt would be considered "slightly larger than full-length," and complementary polynucleotides may be prepared in either of these size ranges that are sufficiently able to specifically bind to native βi-AR-specific mRNA sequences in a host cell and inhibit the ability of the host cell's protein synthesis machinery to translate the native βi-AR-specific mRNA sequence into functional β,-AR polypeptide. Such sequences, therefore, would be ideally suited for the preparation of the genetic constructs of the present invention, particularly in their exploitation as gene therapy vectors for the treatment of the cardiac diseases and disorders of the circulatory system described herein. In the preparation of such gene therapy vectors, one would preferably prepare a genetic construct in which a polynucleotide complementary to the mRNA was placed under the control of a suitable promoter, and then introduce the recombinant vector comprising the genetic construct into the host cells of the affected mammal. Expression of the encoded antisense polynucleotide, therefore, would result in the synthesis of a full-length, substantially full-length, or slightly larger-than full-length polynucleotide that is complementary to the native βi-AR-specific mRNA produced by the cell. This complementary sequence could then specifically bind to the target mRNA and thereby reduce the availability of native βj-AR-specific mRNA for translation into mature polypeptide by the cellular protein synthesis machinery. For the human βi-AR gene shown in SEQ ID NO: 187, exemplary antisense polynucleotide sequences include those that are of from about 1.36-knt to about 1.50-knt in length and that comprise a substantially complementary contiguous sequence selected from about nucleotide 60 to about nucleotide 1600 of SEQ ID NO: 187. The selection of substantially complementary, substantially full-length antisense polynucleotides capable of inhibiting the translation of native human β AR mRNA into polypeptide is within the purview of the skilled artisan having the benefit of the present teaching and the selection methods, computer-based complementarity-defining search algorithms, and the assays for βi-AR mRNA and β r AR polypeptides described herein. In each of the following sequences, the AUG initiation codon is indicated as the first triplet in bold of the corresponding open reading frame. 5.8.1 HUMAN β,-AR The polynucleotide sequence encoding human βj-AR polypeptide is disclosed in Frielle et al.
