RECOMBINANT RIBONUCLEASE PROTEINS

Abstract: The invention relates to ribonucleases derived from a native ribonuclease found in the oocytes of Rana pipiens. Various humanized and recombinant forms of these molecules are described as well as uses for them.

Description: RECOMBINANT RffiONUCLEASE PROTEINS FIELD OF THE INVENTION This invention relates to the production of ribonuclease molecules which are toxic to cells of interest. BACKGROUND OF THE INVENTION Ribonucleases such as ribonuclease A ("RNase A") and their cytotoxicity toward tumor cells are well documented from studies performed in the 1960s and 1970s and reviewed in Roth, J. , 1963, Cancer Res . 23:657-666. Human serum was also discovered to contain several RNases (Reddi, E., 1975, Biochem. Biophys . Res . Commun. 67:110-118, Blank et al . , Human body fluid ribonucleases: detection, interrelationships and significance 1-203-209 (IRL Press, London, 1981)) that are expressed in a tissue specific manner. The proteins involved in the host defense activity of the eosinophil are homologous to RNases and express RNase activity (Gleich et al . , 1986, Proc. Natl . Acad. Sc . , USA 83:3146-3150; Slifman et al . , 1986, J. Immunol , 137:2913-2917) . Thus, human serum RNases were believed to also have host defense activities. Further to these early studies was the discovery that an anti-tumor protein from oocytes of Rana pipiens has homology to RNase A (Ardelt et al . , 1991, J. Biol . Chem. 256:245-251) . This protein has been termed ONCONASE ® , Alfacell Corporation, N.J. See also e.g. , Darzynkiewicz et al . (1988) Cell Tissue Kinet . 21, 169-182, Mikulski et al . (1990) Cell Tissue Kinet . 23, 237-246. This protein is also described in U.S. Patent No. 4,888,172. Phase I and Phase I/II clinical trials of ONCONASE ® as a single therapeutic agent in patients with a variety of solid tumors (Mikulski et al . (1993) Int . J. of Oncology 3, 57-64) or combined with tamoxifen in patients with advanced pancreatic carcinoma have recently been completed (Chun et al . (1995) Proc Amer Soc Clin Oncol 14 No. 157, 210) . Conjugation of ONCONASE ® to cell- type-specific ligands increased its potency towards tumor cells (Rybak et a_I.(1993) Drugr Delivery 1, 3-10). Taken together, these results indicate that ONCONASE ® has properties that are advantageous for the generation of a potent selective cell killing agent. However, since this is not a human-derived protein, it is prone to stimulating undesirable immune responses when used in humans. Thus, it would be desirable to retain the potent cytotoxic properties of this molecule while reducing its immunogenicity in humans. Further, it would be desirable to produce derivations of this molecule recombinantly so that it may be better chemically conjugated or recombinantly joined to other molecules for targeting to specific cells. Until the invention described herein, it has proven difficult to recombinantly express an active cytotoxic molecule related to ONCONASE ® . Though it was thought that the methionine-glutamic acid amino terminal end of the recombinant molecule prohibited the molecule from having significant enzymatic activity, a means to solve this problem has not been forthcoming until the invention herein. Further, although advances in protein design techniques promise to alleviate some of the immunogenicity associated with the antibody portion of immunotoxins (Bird et al . , 1988, Science 242:423; Huston et al . , 1988, Proc Natl Acad Sci USA 85:5879; Ward et al . , 1989, Nature 341:544), no solution has been forthcoming for the immunogenicity of the toxin portion other than immunosuppression of the patients (Khazaeli et al., 1988, Proceedings of AACR 29:418). Thus, there is a continuing need for methods and compositions that would reduce the immunogenicity of the Rana pipiens-derived toxic moiety. Νon-cytotoxic human members of the RΝase A superfamily linked to tumor associated antigens by chemical (Rybak et al . (1991) J. Biol . Chem 266, 1202-21207, Newton et al. (1992) J. Biol . Chem. 267, 19572-19578) or recombinant means (Rybak et al . Proc . Natl . Acad. Sci . U. S.A . 89, 3165, Newton et al. (1994) J Biol Chem. 269, 26739-26745 have been shown to offer a strategy for selectively killing tumor cells with less immunogenicity than current strategies employing plant and bacterial toxins Rybak, S.M. & Youle, R.J. (1991) Immunol , and Allergy Clinics of North America 11:2, 359-380. Human-derived ribonucleases of interest include eosinophil- derived neurotoxin (EDN) and angiogenin. SUMMARY OF THE INVENTION We have discovered how to construct RNases which are highly cytotoxic and which are modifications of the native ONCONASE ® (nOnc) . When the nOnc was expressed recombinantly it was not found to have significant cytotoxicity. Our modified versions (rOnc) , however, are highly cytotoxic and otherwise retain the advantages of the native ONCONASE ® molecules, while in some cases they also have increased cytotoxic properties. The rOnc molecules may be used alone or conveniently used to form chemical conjugates, as well as to form targeted recombinant immunofusions. These rOnc molecules can be used to decrease tumor cell growth. An effective recombinant form of nOnc advantageously permits the recombinant molecule to be fused to other therapeutic or targeting molecules of interest recombinantly. Further, the rOnc molecule can be modified to enhance cytotoxicity as will be seen below. Our nOnc-derived molecules are also desirable because nOnc is a unique ribonuclease in that it can be administered alone directly to patients to decrease and inhibit tumor cell growth without the use of a targeting agent. The present invention also includes methods of selectively killing cells using a rOnc joined to a ligand to create a selective cytotoxic reagent of the present invention. The method comprises contacting the cells to be killed with a cytotoxic reagent of the present invention having a ligand binding moiety that specifically delivers the reagent to the cells to be killed. This method of the present invention may be used for cell separation in vitro by selectively killing unwanted types of cells, for example, in bone marrow prior to transplantation into a patient undergoing marrow ablation by radiation, or for killing leukemia cells or T-cells that would cause graft-versus-host disease. The toxins can also be used to selectively kill unwanted cells in culture. Humanized versions of our rOnc molecules are also described which graft portions of mammalian or human-derived RNases such as angiogenin or human eosinophil derived neurotoxin (EDN) to the rOnc-derived molecules. A preferred embodiment of the invention is a molecule where the amino terminal end of EDN is placed onto the amino terminal end of the rOnc molecules. The surprising properties of these hybrid proteins with regard to ribonuclease activity and in vi tro anti-tumor effects are described.

DETAILED DESCRIPTION This invention provides highly active and cytotoxic ribonuclease molecules which can be used to selectively kill and target cells, particularly tumor cells. In some embodiments the molecules are designed to incorporate sequences from human derived ribonucleases which are also highly active and cytotoxic, but which have the further advantage in that they are less immunogenic in humans. The rOnc molecules of the present invention are those which are recombinant nOnc-derived sequences. The nOnc molecule has an amino acid sequence set forth in SEQ ID NO:l. Bovine pancreatic RNase A has an amino acid sequence set forth in SEQ ID NO:13. Unless otherwise indicated, the amino acid sequence positions described herein use as a frame of reference the bovine pancreatic RNase A sequence in SEQ ID NO:13 as this is the reference sequence commonly used in the RNase field. It should be understood that such position designations do not indicate the number of amino acids in the claimed molecule per se, but indicate where in the claimed molecule the residue occurs when the claimed molecule sequence is aligned with bovine RNase. The rOnc molecules described and claimed herein will preferably have cysteine residues at amino acid positions corresponding to amino acid positions 26, 40, 58, 84, 95 and 110; a lysine at position 41 and a histidine at position 119 with reference to the bovine RNase A, SEQ ID NO:13 (such positions correspond to amino acid position numbers 19, 30, 48, 68, 75 and 90 and 87 and 104 of the nOnc sequence respectively set out in SEQ ID NO:l). The rOnc molecules of this invention are those that have measurable ribonuclease activity, as defined below. The ribonucleases will also have (a) an amino terminal end beginning with a methionine which is followed by any amino acid other than glutamic acid (Glu) ; (b) a cysteine at amino acid positions 26, 40, 58, 84, 95 and 110; a lysine at position 41 and a histidine at position 119, such positions being determined with reference to those in the amino acid sequence of bovine RNase A (SEQ ID NO:13) , and (c) an nOnc-derived amino acid sequence. Preferably, the rOnc molecules will have an amino terminal end selected from the group consisting of: Me -Ala; Met-Ala-Ala-Ser; Met-Arg; Met- (J) ; Met-Lys- (J); Met-Arg- (J) ; Met-Lys; Met-Lys-Pro; Met-Lys- (J) -Pro (SEQ ID NO:14) ; Met-Lys-Pro- (J) (SEQ ID NO:15) ; Met-Asn; Met-Gin; Met-Asn- (J) ; Met -Gin- (J) ; Met -Asn- (J) - Pro (SEQ ID N0 : 16 ) ; Met - (J) - Lys ; Met- (J) -Lys-Pro (SEQ ID N0:17); and Met- (J) -Pro-Lys (SEQ ID N0:18); where (J) is Ser, Tyr or Thr. Further, it is preferred that the rOnc molecules be modified so that the aspartic acid of amino acid position 2 of nOnc (position 4 with reference to the sequence of bovine RNase A) is deleted or replaced by Ala or Asn. In alternative forms of the rOnc molecules, the molecules will employ an amino terminal end encoded by a sequence derived from the amino terminal end of EDN followed by a sequence from rOnc. In such forms, it is preferred that the amino acid sequence is one selected from the group consisting of those sequences substantially identical to those of a formula: Met(-l)EDN (1 . m) Onc (n . 104) wherein Met(-l) refers to an amino terminal residue of Met; wherein EDN (1 . m) refers to a contiguous sequence of amino acids of a length beginning at amino acid position l of EDN (SEQ ID NO:9) and continuing to and including amino acid position "m" of EDN; wherein Onc (n . 104j refers to a sequence of contiguous amino acids beginning at amino acid position "n" and continuing to and including amino acid position 104 as set out in SEQ ID NO:1; such that: when m is 21, n is 16 or 17; when m is 22, n is 17; when m is 20, n is 16, when m is 19, n is 15, when m is 18, n is 14; when m is 17, n is 12 or 13; when m is 16, n is 11, 12, 13 or 14; when m is 15, n is 10; when m is 14, n is 9; when m is 13, n is 8; and when m is 5, n is 1. In other alternative embodiments, the rOnc molecule will be fused at the carboxyl end to a sequence from angiogenin, such as the sequence exemplified in SEQ ID NO:11 or that at amino acid positions 101 to 107 of SEQ ID NO.-20. The nucleic acid sequence for human angiogenin is known and is set out in U.S. Patent Application No. 08/125,462. Preferred rOnc nucleic acid sequences are those that encode preferred rOnc amino acid sequences which are substantially identical to those in SEQ ID NOs:20, 22, 24, 26, 28 and 30 (corresponding nucleic acid sequences are set out in SEQ ID NOs:19, 21, 23, 25, 27 and 29, respectively). Most preferred rOnc amino acid sequences are those that are substantially identical to those set forth in SEQ ID NOs:20, 22, 24 and 26. Their corresponding nucleic acid sequences are also preferred and are set out in SEQ ID NOs:l9, 21, 23 and 25, including conservatively modified variants thereof. The most preferred sequence includes SEQ ID NO:22, one which employs an amino terminal end comprising 1 to 21 (typically 21) amino acids of the amino terminal end of EDN grafted on to 16 to 104 amino acids of the nOnc sequence, with amino acid residue 20 in nOnc (Asp) being replaced with Gly. Preferred rOnc sequences further will contain optionally a Cys at a position corresponding to amino acid position 5, or 73 or Ala at amino acid position 88 in place of Cys with reference to SEQ ID NO:39. Comparisons of the rOnc sequences provided here can be made to described sequences in the pancreatic RNase A superfamily. Many of such members are known and include, but are not limited to, frog lectin from Rana catesbeiana (Titani et al., Biochemistry 26:2189 (1987)); ONCONASE ® (Ardelt, W. et al., J. Biol . Chem. 266:245 (1991)); eosinophil derived neurotoxin (EDN) (Rosenberg et al . , supra) ; human eosinophil cationic protein (ECP) (Rosenberg et al . , J. Exp. Med. 170:163 (1989)); angiogenin (Ang) (Fett, J.W. et al., Biochemistry 24:5480 (1985)); bovine seminal RNase (Preuss et al . , Nuc. Acids. Res. 18:1057 (1990)); and bovine pancreatic RNase (Beintama et al . , Prog. Biophys . Mol . Biol . 51:165 (1988)) , references for all such proteins are incorporated by reference herein. Amino acid sequence alignment for such RNases are also set out in Fig. 4 and in Youle et al . , Cri t . Rev. Ther. Drug. Carrier Systems 10:1-28 (1993) and in U.S. Patent Application Serial No. 08/125,462, which is incorporated by reference herein. Definitions. Unless defined otherwise herein, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Singleton et al . (1994) Dictionary of Microbiology and Molecular Biology, second edition, John Wiley and Sons (New York) , and Hale and Marham (1991) The Harper Collins Dictionary of Biology, Harper Perennial, NY provide one of skill with a general dictionary of many of the terms used in this invention. Although any methods and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, the preferred methods and materials are described. For purposes of the present invention, the following terms are defined below. Amino acids may be referred to herein by either their commonly known three letter symbols or by the one-letter symbols recommended by the IUPAC-IUB Biochemical Nomenclature Commission. Nucleotides, likewise, may be referred to by their commonly accepted single-letter codes. The terms "measurable ribonuclease activity" or "significant ribonuclease activity" refer to a molecule which has an IC 50 (ng/ml) of less than 40 when added to a rabbit reticulocyte lysate assay wherein protein synthesis is inhibited as measured by the incorporation of [ 35 S]methionine into acid precipitable protein. IC 50 is the concentration of protein necessary to inhibit protein synthesis by 50% in the assay. The lysate assay may be done as described in the Promega lysate assay kit which is commercially available from Promega Corporation, Madison, WI. Ribonuclease activity using high molecular weight RNA and tRNA is determined at 37°C through the formation of perchloric acid soluble nucleotides following published protocols (Newton, D.L., et al . (1996) Biochemistry 35:545-553) . With poly(A,C) UpG and poly U, ribonuclease activity is assayed according to DePrisco et al . , and Libonati and Floridi (DePrisco, R. , et al . (1984) Biochimica et Biophysica Acta 788:356-363; Libonati, M. et al . (1969) European J. Biochem. 8:81-87) . Activity is assayed by measuring the increase with time in absorbance at 260 nm. Incubation mixtures (1 ml of 10 mM imidazole, 0.1 M NaCl, pH 6.5 or pH 7) contain substrate and appropriate amounts of enzyme solution at 25°C. The in vitro translation assay (St. Clair, D.K., et al . (1987) Proc. Natl . Acad. Sci . 84:8330- 8334) and the cell viability assays using the (3- [4,5- Dimethylthiazol-2-yl] -2,5-diphenyltetrazolium bromide; Thiazolyl blue) (MMT) (Mossman, T. (1983) J. Immunol . Methods 65:55-63) are performed as previously described (Pearson, J.W. , et al . (1991) J. Natl . Cancer Inst . 83:1386-1391). An "nOnc-derived" amino acid sequence is one that contains at least one string of six contiguous amino acids which is identical to a contiguous sequence of six amino acids selected from the group of sequences beginning at amino acid positions 1 (with Glu replacing pyroGlu) , 2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15, 16, 18, 19, 20, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 41, 42, 43, 44, 45, 46, 47, 50, 52, 54, 56, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 76, 80, 81, 82, 84, 85, 86, 87, 91, 92, 93, 95, or 96 of the nOnc amino acid sequence (SEQ ID NO:1) . "Conservatively modified variations" of a particular nucleic acid sequence refer to those nucleic acids which encode identical or essentially identical amino acid sequences, or where the nucleic acid does not encode an amino acid sequence, to essentially identical sequences. Because of the degeneracy of the genetic code, a large number of functionally identical nucleic acids encode any given polypeptide. For instance, the codons GCA, GCC, GCG and GCU all encode the amino acid alanine. Thus, at every position where an alanine is specified by a codon, the codon can be altered to any of the corresponding codons described without altering the encoded polypeptide. Such nucleic acid variations are "silent variations, " which are one species of conservatively modified variations. Every nucleic acid sequence herein which encodes a polypeptide also describes every possible silent variation of the nucleic acid. One of skill will recognize that each codon in a nucleic acid (except AUG, which is ordinarily the only codon for methionine) can be modified to yield a functionally identical molecule. Accordingly, each silent variation of a nucleic acid which encodes a polypeptide is implicit in each described sequence. Furthermore, one of skill will recognize that individual substitutions, deletions or additions which alter, add or delete a single amino acid or a small percentage of amino acids in an encoded sequence are "conservatively modified variations" where the alterations result in the substitution of an amino acid with a chemically similar amino acid. Conservative substitution tables providing functionally similar amino acids are well known in the art. The following six groups each contain amino acids that are conservative substitutions for one another: 1) Alanine (A) , Serine (S) , Threonine (T) ; 2) Aspartic acid (D) , Glutamic acid (E) ; 3) Asparagine (N) , Glutamine (Q) ; 4) Arginine (R) , Lysine (K) ; 5) Isoleucine (I) , Leucine (L) , Methionine (M) , Valine (V) ; and 6) Phenylalanine (F) , Tyrosine (Y) , Tryptophan (W) . See also, Creighton (1984) Proteins W.H. Freeman and Company. The terms "isolated" or "biologically pure" refer to material which is substantially or essentially free from components which normally accompany it as found in its naturally occurring environment. The isolated material optionally comprises material not found with the material in its natural environment. The rOncs described herein are isolated and biologically pure since they are recombinantly produced in the absence of unrelated Rana pipiens proteins. They may, however, include heterologous cell components, a ligand binding moiety, a label and the like. The term "nucleic acid" refers to a deoxyribonucleotide or ribonucleotide polymer in either single- or double-stranded form, and unless otherwise limited, encompasses known analogues of natural nucleotides that hybridize to nucleic acids in a manner similar to naturally occurring nucleotides. Unless otherwise indicated, a particular nucleic acid sequence includes the complementary sequence thereof. A nucleic acid encodes another nucleic acid where it is the same as the specified nucleic acid, or complementary to the specified nucleic acid. An "expression vector" includes a recombinant expression cassette which includes a nucleic acid which encodes a rOnc polypeptide which can be transcribed and translated by a cell. A recombinant expression cassette is a nucleic acid construct, generated recombinantly or synthetically, with a series of specified nucleic acid elements which permit transcription of a particular nucleic acid in a target cell. The expression vector can be part of a plasmid, virus, or nucleic acid fragment. Typically, the recombinant expression cassette portion of the expression vector includes a nucleic acid to be transcribed, and a promoter. The term "recombinant" when used with reference to a protein indicates that a cell expresses a peptide or protein encoded by a nucleic acid whose origin is exogenous to the cell. Recombinant cells can express genes that are not found within the native (non-recombinant) form of the cell. Recombinant cells can also express genes found in the native form of the cell wherein the genes are re-introduced into the cell by artificial means, for example under the control of a heterologous promoter. The term "subsequence" in the context of a particular nucleic acid or polypeptide sequence refers to a region of the nucleic acid or polypeptide equal to or smaller than the particular nucleic acid or polypeptide. "Stringent hybridization wash conditions" in the context of nucleic acid hybridization experiments such as Southern and northern hybridizations are sequence dependent, and are different under different environmental parameters. An extensive guide to the hybridization of nucleic acids is found in Tijssen (1993) Laboratory Techniques in Biochemistry and Molecular Biology- -Hybridization wi th Nucleic Acid Probes Part I, Chapter 2 "Overview of principles of hybridization and the strategy of nucleic acid probe assays", Elsevier, New York. Generally, highly stringent wash conditions are selected to be about 5° C lower than the thermal melting point (T m ) for the specific sequence at a defined ionic strength and ph. The T m is the temperature (under defined ionic strength and pH) at which 50% of the target sequence hybridizes to a perfectly matched probe. Very stringent conditions are selected to be equal to the T m point for a particular probe. Nucleic acids which do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides which they encode are substantially identical. This occurs, e. g. , when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. The term "identical" in the context of two nucleic acid or polypeptide sequences refers to the residues in the two sequences which are the same when aligned for maximum correspondence over a specified comparison window. When percentage of sequence identity is used in reference to proteins or peptides it is recognized that residue positions which are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted for other amino acid residues with similar chemical properties (e.g. charge or hydrophobicity) and therefore do not change the functional properties of the molecule. Where sequences differ in conservative substitutions, the percent sequence identity may be adjusted upwards to correct for the conservative nature of the substitution. Means for making this adjustment are well-known to those of skill in the art. Typically this involves scoring a conservative substitution as a partial rather than a full mismatch, thereby increasing the percentage sequence identity. Thus, for example, where an identical amino acid is given a score of 1 and a non-conservative substitution is given a score of zero, a conservative substitution is given a score between zero and l. The scoring of conservative substitutions is calculated, e. g. , according to the algorithm of Meyers and Miller, Computer Applic. Biol. Sci., 4: 11-17 (1988) e . g. , as implemented in the program PC/GENE (Intelligenetics, Mountain View, California, USA) . Methods of alignment of sequences for comparison are well-known in the art. Optimal alignment of sequences for comparison may be conducted by the local homology algorithm of Smith and Waterman (1981) Adv. Appl . Math . 2: 482; by the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol . Biol . 48: 443; by the search for similarity method of Pearson and Lipman (1988) Proc . Natl . Acad. Sci . USA 85: 2444; by computerized implementations of these algorithms (including, but not limited to CLUSTAL in the PC/Gene program by Intelligenetics, Mountain View, California, GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group (GCG) , 575 Science Dr. , Madison, Wisconsin, USA) ; the CLUSTAL program is well described by Higgins and Sharp (1988) Gene, 73: 237-244 and Higgins and Sharp (1989) Computer Applications in the Biosciences 5: 151-153; Corpet, et al . (1988) Nucleic Acids Research 16, 10881-90; Huang, et al . (1992) Computer Applications in the Biosciences 8, 155-65, and Pearson, et al . (1994) Methods in Molecular Biology 24, 307-31. Alignment is also often performed by inspection and manual alignment. The term "substantial identity" or "substantial similarity" in the context of a polypeptide indicates that a polypeptide comprises a sequence with at least 70% sequence identity to a reference sequence, or preferably 80%, or more preferably 85% sequence identity to the reference sequence, or most preferably 90% identity over a comparison window of about 10-20 amino acid residues. An indication that two polypeptide sequences are substantially identical is that one peptide is immunologically reactive with antibodies raised against the second peptide. Thus, a polypeptide is substantially identical to a second polypeptide, for example, where the two peptides differ only by a conservative substitution. One indication that two nucleic acid sequences are substantially identical is that the polypeptide which the first nucleic acid encodes is i munologically cross reactive with the polypeptide encoded by the second nucleic acid. Another indication that two nucleic acid sequences are substantially identical is that the two molecules hybridize to each other under stringent conditions. Stringent conditions are sequence dependent and are different under different environmental parameters. Generally, stringent conditions are selected to be about 5° C to 20°C lower than the thermal melting point (T m ) for the specific sequence at a defined ionic strength and pH. The T m is the temperature (under defined ionic strength and pH) at which 50% of the target sequence hybridizes to a perfectly matched probe. However, nucleic acids which do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides which they encode are substantially identical. This occurs, e .g. , when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. The term "specifically deliver" as used herein refers to the preferential association of a molecule with a cell or tissue bearing a particular target molecule or marker and not to cells or tissues lacking that target molecule. It is, of course, recognized that a certain degree of non¬ specific interaction may occur between a molecule and a non- target cell or tissue. Nevertheless, specific delivery, may be distinguished as mediated through specific recognition of the target molecule. Typically specific delivery results in a much stronger association between the delivered molecule and cells bearing the target molecule than between the delivered molecule and cells lacking the target molecule. Specific delivery typically results in greater than 2 fold, preferably greater than 5 fold, more preferably greater than 10 fold and most preferably greater than 100 fold increase in amount of delivered molecule (per unit time) to a cell or tissue bearing the target molecule as compared to a cell or tissue lacking the target molecule or marker. The term "residue" as used herein refers to an amino acid that is incorporated into a polypeptide. The amino acid may be a naturally occurring amino acid and, unless otherwise limited, may encompass known analogs of natural amino acids that can function in a similar manner as naturally occurring amino acids. A "fusion protein" or when a molecule is "joined" to another refers to a chimeric molecule formed by the joining of two or more polypeptides through a peptide bond formed between the amino terminus of one polypeptide and the carboxyl terminus of another polypeptide. The fusion protein or the joined molecules may be formed by the chemical coupling of the constituent molecules or it may be expressed as a single polypeptide from a nucleic acid sequence encoding a single contiguous fusion protein. A single chain fusion protein is a fusion protein having a single contiguous polypeptide backbone. A "ligand" or a "ligand binding moiety", as used herein, refers generally to all molecules capable of specifically delivering a molecule, reacting with or otherwise recognizing or binding to a receptor on a target cell. Specifically, examples of ligands include, but are not limited to, antibodies, lymphokines, cytokines, receptor proteins such as CD4 and CD8, solubilized receptor proteins such as soluble CD4, hormones, growth factors, and the like which specifically bind desired target cells. Making rOnc-derived Nucleic Acids and Polypeptides. Several specific nucleic acids encoding rOnc-derived polypeptides are described herein. These nucleic acids can be made using standard recombinant or synthetic techniques. Given the nucleic acids of the present invention, one of skill can construct a variety of clones containing functionally equivalent nucleic acids, such as nucleic acids which encode the same polypeptide. Cloning methodologies to accomplish these ends, and sequencing methods to verify the sequence of nucleic acids are well known in the art. Examples of appropriate cloning and sequencing techniques, and instructions sufficient to direct persons of skill through many cloning exercises are found in Berger and Kimmel, Guide to Molecular Cloning Techniques , Methods in Enzymology volume 152 Academic Press, Inc., San Diego, CA (Berger); Sambrook et al . (1989) Molecular Cloning - A Laboratory Manual (2nd ed.) Vol. 1-3; and Current Protocols in Molecular Biology, F.M. Ausubel et al . , eds., Current Protocols, a joint venture between Greene Publishing Associates, Inc. and John Wiley & Sons, Inc., (1994 Supplement) (Ausubel). Product information from manufacturers of biological reagents and experimental equipment also provide information useful in known biological methods. Such manufacturers include the SIGMA chemical company (Saint Louis, MO) , R&D systems (Minneapolis, MN) , Pharmacia LKB Biotechnology (Piscataway, NJ) , CLONTECH Laboratories, Inc. (Palo Alto, CA) , Chem Genes Corp., Aldrich Chemical Company (Milwaukee, WI) , Glen Research, Inc., GIBCO BRL Life Technologies, Inc. (Gaithersberg, MD) , Fluka Chemica-Biochemika Analytika (Fluka Chemie AG, Buchs, Switzerland) , Invitrogen, San Diego, CA, and Applied Biosystems (Foster City, CA) , as well as many other commercial sources known to one of skill. The nucleic acid compositions of this invention, whether RNA, cDNA, genomic DNA, or a hybrid of the various combinations, are isolated from biological sources or synthesized in vitro. The nucleic acids of the invention are present in transformed or transfected cells, in transformed or transfected cell lysates, or in a partially purified or substantially pure form. In vitro amplification techniques suitable for amplifying sequences for use as molecular probes or generating nucleic acid fragments for subsequent subcloning are known. Examples of techniques sufficient to direct persons of skill through such in vi tro amplification methods, including the polymerase chain reaction (PCR) the ligase chain reaction (LCR) , Q / 8-replicase amplification and other RNA polymerase mediated techniques (e.g., NASBA) are found in Berger, Sambrook et al .

Oligonucleotides for use as probes, e .g. , in in vitro rOnc nucleic acid amplification methods, or for use as nucleic acid probes to detect rOnc nucleic acids are typically synthesized chemically according to the solid phase phosphoramidite triester method described by Beaucage and Caruthers (1981), Tetrahedron Letts . , 22 (20) :1859-1862, e.g. , using an automated synthesizer, e .g. , as described in Needham-VanDevanter et al . (1984) Nucleic Acids Res. , 12:6159-6168. Oligonucleotides can also be custom made and ordered from a variety of commercial sources known to persons of skill. Purification of oligonucleotides, where necessary, is typically performed by either native acrylamide gel electrophoresis or by anion-exchange HPLC as described in Pearson and Regnier (1983) J. Chrom. 255:137-149. The sequence of the synthetic oligonucleotides can be verified using the chemical degradation method of Maxam and Gilbert (1980) in Grossman and Moldave (eds.) Academic Press, New York, Methods in Enzy ology 65:499-560. One of skill will recognize many ways of generating desired alterations in a given nucleic acid sequence. Such well-known methods include site-directed mutagenesis, PCR amplification using degenerate oligonucleotides, exposure of cells containing the nucleic acid to mutagenic agents or radiation, chemical synthesis of a desired oligonucleotide ( e .g. , in conjunction with ligation and/or cloning to generate large nucleic acids) and other well-known techniques. See, Giliman and Smith (1979) Gene 8:81-97; Roberts et al . (1987) Nature 328:731-734 and Sambrook et al . (1989) Afolecular Cloning - A Laboratory Manual (2nd Ed) Vol. 1-3; Innis, Ausbel, Berger, Needham VanDevanter and Mullis (all supra) . Polypeptides of the invention can be synthetically prepared in a wide variety of well-known ways. Polypeptides of relatively short size are typically synthesized in solution or on a solid support in accordance with conventional techniques. See, e.g. , Merrifield (1963) J. Am. Chem . Soc. 85:2149-2154. Various automatic synthesizers and sequencers are commercially available and can be used in accordance with known protocols. See, e. g. , Stewart and Young (1984) Solid Phase Peptide Synthesis, 2d. ed. , Pierce Chemical Co. Polypeptides are also produced by recombinant expression of a nucleic acid encoding the polypeptide followed by purification using standard techniques. Making Conservative Modifications of the Nucleic Acids and Polypeptides of the Invention. One of skill will appreciate that many conservative variations of the sequences disclosed yield a substantially identical rOnc. For example, due to the degeneracy of the genetic code, "silent substitutions" (i.e., substitutions of a nucleic acid sequence which do not result in an alteration in an encoded polypeptide) are an implied feature of every nucleic acid sequence which encodes an amino acid. Similarly, conservative amino acid substitutions, in one or a few amino acids in an amino acid sequence are substituted with different amino acids with highly similar properties (see, the definitions section, supra) , are also readily identified as being highly similar to a disclosed amino acid sequence, or to a disclosed nucleic acid sequence which encodes an amino acid. Such conservatively substituted (or modified) variations of each explicitly disclosed sequence are a feature of the present invention. One of skill will recognize many ways of generating alterations in a given nucleic acid sequence. Such well-known methods include site-directed mutagenesis, PCR amplification using degenerate oligonucleotides, exposure of cells containing the nucleic acid to mutagenic agents or radiation, chemical synthesis of a desired oligonucleotide (e.g., in conjunction with ligation and/or cloning to generate large nucleic acids) and other well-known techniques. See, Giliman and Smith (1979) Gene 8:81-97, Roberts et al . (1987) Nature 328:731-734 and Sambrook, Innis, Ausbel, Berger, Needham VanDevanter and Mullis (all supra) . Most commonly, polypeptide sequences are altered by changing the corresponding nucleic acid sequence and expressing the polypeptide. However, polypeptide sequences are also optionally generated synthetically using commercially available peptide synthesizers to produce any desired polypeptide ( see, Merrifield, and Stewart and Young, supra) . One of skill can select a desired nucleic acid or polypeptide of the invention based upon the sequences provided and upon knowledge in the art regarding ribonucleases generally. The physical characteristics and general properties of RNases are known to skilled practitioners. The specific effects of some mutations in RNases are known. Moreover, general knowledge regarding the nature of proteins and nucleic acids allows one of skill to select appropriate sequences with activity similar or equivalent to the nucleic acids and polypeptides disclosed in the sequence listings herein. The definitions section herein describes exemplary conservative amino acid substitutions. Finally, most modifications to nucleic acids and polypeptides are evaluated by routine screening techniques in suitable assays for the desired characteristic. For instance, changes in the immunological character of a polypeptide can be detected by an appropriate immunological assay. Modifications of other properties such as nucleic acid hybridization to a target nucleic acid, redox or thermal stability of a protein, thermal histeresis, hydrophobicity, susceptibility to proteolysis, or the tendency to aggregate are all assayed according to standard techniques. rOnc Fusion Proteins and Other Therapeutic Moieties. The rOnc molecules may also include pharmacological agents or encapsulation systems containing various pharmacological agents. They typically will include a ligand to act as a targeting molecule to direct the rOnc to desired cells. The rOnc may be attached directly to a ligand or an antisense molecule which will assist in delivering the rOnc. See, for example, SEQ ID NOS:40-61. The rOnc can also be engineered to contain a nuclear localization signal ("NLS") such as that described in amino acid positions l to 7 in SEQ ID NO:32 (and SEQ ID NO:31) to direct the rOnc within the cell. Alternatively, the Met at position 8 and the corresponding nucleic acids at positions 22-24 of SEQ ID NO:31 has been and can be omitted. The nucleic acid sequence for the NLS is nucleic acids 1-21 of SEQ ID NO:31. A signal peptide is also exemplified at amino acid positions 1-25 of SEQ ID NO:63. The rOnc molecules are uniquely adapted for gene therapy applications. They can be fused to other therapeutic agents, for example, they could be fused to an anti-B cell lymphoma antibody. For example, as will be explained in more detail below, rOnc molecules recombinantly fused to an anti- transferrin receptor antibody or an anti-colon cancer antibody were active. As mentioned above, nOnc has anti-tumor effects in vivo and preferentially kills rapidly dividing cells stimulated by serum or growth promoting agents such as ras. The molecules are readily internalized in the cell. Their activity can be further facilitated by joining them to a nuclear localization signal and the like to redirect the molecules within the cell. Of particular use in tumor cells would be to target telomerase, an enzyme subject to degradation by RNase. We have found that One synergizes with ras in microinjection studies. This means that One and ras have to be together in the cell. One does not synergize with ras when it enters the cell via its own routing. A CAAX (SEQ ID NO:33) motif is required to localize ras at the plasma membrane (C=Cys, A = an aliphatic amino acid, X = S,M,C,A, or Q, an example is Cys-Val-Ile-Met (SEQ ID N0:34)). Importantly this type of sequence has been shown to target heterologous proteins to the plasma membrane (Hancock, J. , Cadwallader, K. , Paterson, H. and C. Marshall (1991) EMBO J. 10:4033). It would be desirable to join the rOnc gene with DNA encoding a CAAX (SEQ ID NO:33) signal as given in the example, or KDEL as described below. Telomerase is being investigated as a "universal cancer target" (G.B. Morin, JNCI. (1995) 87:859). It is an RNA protein that is located in the nucleus. It has been shown that antisense to telomerase RNA can inhibit the function of the enzyme and block the growth of cancer cells (J. Feng et al., Science (1995) 269:1236). RNase can also destroy the activity of the enzyme. One can also destroy the activity of the enzyme when incubated with a cell extract containing telomerase. An NLS/Onc molecule (such as that set out in SEQ ID NO: 32) can be made to route One to the nucleus so that it can degrade telomerase. The NLS we used has been shown to redirect proteins to the nucleus for the aim of interfering with the function of a nuclear antigen (S. Biocca, M. S. Neuberger and A. Cattaneo, (1990) 9:101). Our NLS/Onc molecule is effective in killing cells. An amino terminal sequence to the recombinant molecule may be preferred where it is desirable to translocate the molecule into the cytosol of target cells. Such signal peptide is typically inserted at the amino end of the protein. For example, the first amino acids of the recombinant molecules described herein (after Met) could be KDEL (SEQ ID NO:64) and would accomplish signalling the molecule to the endoplasmic reticulum. Amino acid sequences which include KDEL, repeats of KDEL, or other sequences that function to maintain or recycle proteins into the endoplasmic reticulum, referred to here as "endoplasmic retention sequences" may be employed. Optionally, the rOnc molecule attached to a ligand may include an encapsulation system, such as a liposome or micelle that contains an additional therapeutic composition such as a drug, a nucleic acid ( e . g. an antisense nucleic acid) , or another therapeutic moiety that is preferably shielded from direct exposure to the circulatory system. Means of preparing liposomes attached to antibodies are well known to those of skill in the art. See, for example, U.S. Patent No. 4,957,735, Connor et al . , Pharm. Ther. , 28: 341-365 (1985) . One of skill will appreciate that the ligand molecule or other therapeutic component and the rOnc molecule may be joined together in any order. Thus, where the ligand is a polypeptide, the rOnc molecule may be joined to either the amino or carboxy termini of the ligand or may also be joined to an internal region of either molecule as long as the attachment does not interfere with the respective activities of the molecules. The molecules may be attached by any of a number of means well-known to those of skill in the art. Typically the rOnc will be conjugated, either directly or through a linker (spacer) , to the ligand. However, where both the rOnc and the ligand or other therapeutic are polypeptides it is preferable to recombinantly express the chimeric molecule as a single- chain fusion protein. In one embodiment, the rOnc molecule is chemically conjugated to another molecule ( e . g. a cytotoxin, a label, a ligand, or a drug or liposome) . Means of chemically conjugating molecules are well-known to those of skill. The procedure for attaching an agent to an antibody or other polypeptide targeting molecule will vary according to the chemical structure of the agent. Polypeptides typically contain a variety of functional groups; e . g. , carboxylic acid (COOH) or free amine (-NH 2 ) groups, which are available for reaction with a suitable functional group on an rOnc molecule to bind the other molecule thereto. Alternatively, the ligand and/or rOnc molecule may be derivatized to expose or attach additional reactive functional groups. The derivatization may involve attachment of any of a number of linker molecules such as those available from Pierce Chemical Company, Rockford Illinois. A "linker", as used herein, is a molecule that is used to join two molecules. The linker is capable of forming covalent bonds to both molecules. Suitable linkers are well known to those of skill in the art and include, but are not limited to, straight or branched-chain carbon linkers, heterocyclic carbon linkers, or peptide linkers. Where both molecules are polypeptides, the linkers may be joined to the constituent amino acids through their side groups ( e . g. , through a disulfide linkage to cysteine) . However, in a preferred embodiment, the linkers will be joined to the alpha carbon amino and carboxyl groups of the terminal amino acids. A bifunctional linker having one functional group reactive with a group on a particular agent, and another group reactive with an antibody, may be used to form a desired immunoconjugate. Alternatively, derivatization may involve chemical treatment of the ligand, e . g. , glycol cleavage of the sugar moiety of a glycoprotein antibody with periodate to generate free aldehyde groups. The free aldehyde groups on the antibody may be reacted with free amine or hydrazine groups on an agent to bind the agent thereto. (See U.S. Patent No. 4,671,958). Procedures for generation of free sulfhydryl groups on polypeptides, such as antibodies or antibody fragments, are also known (See U.S. Pat. No. 4,659,839) . Many procedure and linker molecules for attachment of various compounds including radionuclide metal chelates, toxins and drugs to proteins such as antibodies are known. See, for example, European Patent Application No. 188,256; U.S. Patent Nos. 4,671,958, 4,659,839, 4,414,148, 4,699,784; 4,680,338; 4,569,789; and 4,589,071; and Borlinghaus et al . Cancer Res. 47: 4071-4075 (1987) which are incorporated herein by reference. In particular, production of various immunotoxins is well-known within the art and can be found, for example in "Monoclonal Antibody-Toxin Conjugates: Aiming the Magic Bullet," Thorpe et al . , Monoclonal Antibodies in Clinical Medicine, Academic Press, pp. 168-190 (1982), Waldmann, Science, 252: 1657 (1991), U.S. Patent Nos. 4,545,985 and 4,894,443 which are incorporated herein by reference. In some circumstances, it is desirable to free the rOnc from the ligand when the chimeric molecule has reached its target site. Therefore, chimeric conjugates comprising linkages which are cleavable in the vicinity of the target site may be used when the effector is to be released at the target site. Cleaving of the linkage to release the agent from the ligand may be prompted by enzymatic activity or conditions to which the immunoconjugate is subjected either inside the target cell or in the vicinity of the target site. When the target site is a tumor, a linker which is cleavable under conditions present at the tumor site ( e . g. when exposed to tumor-associated enzymes or acidic pH) may be used. A number of different cleavable linkers are known to those of skill in the art. See U.S. Pat. Nos. 4,618,492; 4,542,225, and 4,625,014. The mechanisms for release of an agent from these linker groups include, for example, irradiation of a photolabile bond and acid-catalyzed hydrolysis. U.S. Pat. No. 4,671,958, for example, includes a description of immunoconjugates comprising linkers which are cleaved at the target site in vivo by the proteolytic enzymes of the patient's complement system. In view of the large number of methods that have been reported for attaching a variety of radiodiagnostic compounds, radiotherapeutic compounds, drugs, toxins, and other agents to antibodies one skilled in the art will be able to determine a suitable method for attaching a given agent to an antibody or other polypeptide. Production of rOnc Molecules or Fusion Proteins Where the molecules of interest are relatively short (i.e., less than about 50 amino acids) they may be synthesized using standard chemical peptide synthesis techniques. Where two molecules of interest are relatively short the chimeric molecule may be synthesized as a single contiguous polypeptide. Alternatively the molecules may be synthesized separately and then fused by condensation of the amino terminus of one molecule with the carboxyl terminus of the other molecule thereby forming a peptide bond. Alternatively, the molecules may each be condensed with one end of a peptide spacer molecule thereby forming a contiguous fusion protein. Solid phase synthesis in which the C-terminal amino acid of the sequence is attached to an insoluble support followed by sequential addition of the remaining amino acids in the sequence is the preferred method for the chemical synthesis of the polypeptides of this invention. Techniques for solid phase synthesis are described by Barany and Merrifield, Solid-Phase Peptide Synthesis; pp. 3-284 in The Peptides : Analysis, Synthesis, Biology. Vol . 2 : Special Methods in Peptide Synthesis, Part A. , Merrifield, et al . J. Am. Chem. Soc , 85: 2149-2156 (1963), and Stewart et al . , Solid Phase Peptide Synthesis, 2nd ed. Pierce Chem. Co., Rockford, 111. (1984) which are incorporated herein by reference. In a preferred embodiment, the chimeric fusion proteins of the present invention are synthesized using recombinant DNA methodology. Generally this involves creating a DNA sequence that encodes the fusion protein, placing the DNA in an expression cassette under the control of a particular promoter, expressing the protein in a host, isolating the expressed protein and, if required, renaturing the protein. DNA encoding the fusion proteins of this invention, as well as the rOnc molecules themselves, may be prepared by any suitable method, including, for example, cloning and restriction of appropriate sequences or direct chemical synthesis by methods such as the phosphotriester method of Narang et al . Meth. Enzymol . 68: 90-99 (1979); the phosphodiester method of Brown et al . , Meth. Enzymol . 68: 109-151 (1979); the diethylphosphoramidite method of Beaucage et al . , Tetra . Lett. , 22: 1859-1862 (1981); and the solid support method of U.S. Patent No. 4,458,066, all incorporated by reference herein. Chemical synthesis produces a single-stranded oligonucleotide. This may be converted into double-stranded DNA by hybridization with a complementary sequence, or by polymerization with a DNA polymerase using the single strand as a template. One of skill would recognize that while chemical synthesis of DNA is limited to sequences of about 100 bases, longer sequences may be obtained by the ligation of shorter sequences. Alternatively, subsequences may be cloned and the appropriate subsequences cleaved using appropriate restriction enzymes. The fragments may then be ligated to produce the desired DNA sequence. In a preferred embodiment, DNA encoding fusion proteins or rOnc molecules of the present invention may be cloned using DNA amplification methods such as polymerase chain reaction (PCR) . If two molecules are joined together, one of skill will appreciate that the molecules may be separated by a peptide spacer consisting of one or more amino acids. Generally the spacer will have no specific biological activity other than to join the proteins or to preserve some minimum distance or other spatial relationship between them. However, the constituent amino acids of the spacer may be selected to influence some property of the molecule such as the folding, net charge, or hydrophobicity. The nucleic acid sequences encoding the rOnc molecules or the fusion proteins may be expressed in a variety of host cells, including E. coli , other bacterial hosts, yeast, and various higher eukaryotic cells such as the COS, CHO and HeLa cells lines and myeloma cell lines. The recombinant protein gene will be operably linked to appropriate expression control sequences for each host. For E. coli this includes a promoter such as the T7, trp, or lambda promoters, a ribosome binding site and preferably a transcription termination signal. For eukaryotic cells, the control sequences will include a promoter and preferably an enhancer derived from immunoglobulin genes, SV40, cytomegalovirus, etc., and a polyadenylation sequence, and may include splice donor and acceptor sequences. The expression vectors or plasmids of the invention can be transferred into the chosen host cell by well-known methods such as calcium chloride transformation for E. coli and calcium phosphate treatment or electroporation for mammalian cells. Cells transformed by the plasmids can be selected by resistance to antibiotics conferred by genes contained on the plasmids, such as the amp, gpt, neo and hyg genes. Once expressed, the recombinant rOnc or fusion proteins can be purified according to standard procedures of the art, including ammonium sulfate precipitation, affinity columns, column chromatography, gel electrophoresis and the like ( see, generally, R. Scopes, Protein Purification, Springer-Verlag, N.Y. (1982), Deutscher, Methods in Enzymology Vol . 182 : Guide to Protein Purification . , Academic Press, Inc. N.Y. (1990)). Substantially pure compositions of at least about 90 to 95% homogeneity are preferred, and 98 to 99% or more homogeneity are most preferred for pharmaceutical uses. Once purified, partially or to homogeneity as desired, the polypeptides may then be used therapeutically. Accordingly, this invention also provides for host cells and expression vectors comprising the nucleic acid sequences described above. Further, the present invention includes a method of selectively killing cells using a rOnc joined to a ligand to create a selective cytotoxic reagent of the present invention. The method comprises contacting the cells to be killed with a cytotoxic reagent of the present invention having a ligand binding moiety that specifically delivers the reagent to the cells to be killed. This method of the present invention may be used for cell separation in vi tro by selectively killing unwanted types of cells, for example, in bone marrow prior to transplantation into a patient undergoing marrow ablation by radiation, for killing leukemia cells or T-cells that would cause graft-versus-host disease. For methods of use in vivo, preferably the mammalian protein of the reagent used in this method is endogenous to the species in which the reagent is intended for use. Preferably, for use in humans, the cytotoxic reagent is a fusion protein comprising a humanized chimeric antibody and a humanized rOnc. Specific in vivo methods of this invention include a method for the chemotherapeutic alleviation of cancer in mammals comprising administering a cytotoxic amount of a selective cytotoxic reagent according to the present invention. The methods are particularly useful for treating tumors sensitive to the cytotoxic reagents. Tumors of particular interest include pancreatic, colon, breast and kidney tumors. Pharmaceutical Compositions The rOnc molecules and fusion proteins employing them of this invention are useful for parenteral, topical, oral, or local administration, such as by aerosol or transdermally, for prophylactic and/or therapeutic treatment. The pharmaceutical compositions can be administered in a variety of unit dosage forms depending upon the method of administration. For example, unit dosage forms suitable for oral administration include powder, tablets, pills, capsules and lozenges. It is recognized that the subject molecules and fusion proteins and pharmaceutical compositions of this invention, when administered orally, must be protected from digestion. This is typically accomplished either by complexing the protein with a composition to render it resistant to acidic and enzymatic hydrolysis or by packaging the protein in an appropriately resistant carrier such as a liposome. Means of protecting proteins from digestion are well known in the art. The pharmaceutical compositions of this invention are particularly useful for parenteral administration, such as intravenous administration or administration into a body cavity or lumen of an organ. The compositions for administration will commonly comprise a solution of the chimeric molecule dissolved in a pharmaceutically acceptable carrier, preferably an aqueous carrier. A variety of aqueous carriers can be used, e . g. , buffered saline and the like. These solutions are sterile and generally free of undesirable matter. These compositions may be sterilized by conventional, well known sterilization techniques. The compositions may contain pharmaceutically acceptable auxiliary substances as required to approximate physiological conditions such as pH adjusting and buffering agents, toxicity adjusting agents and the like, for example, sodium acetate, sodium chloride, potassium chloride, calcium chloride, sodium lactate and the like. The concentration of therapeutic molecule in these formulations can vary widely, and will be selected primarily based on fluid volumes, viscosities, body weight and the like in accordance with the particular mode of administration selected and the patient's needs. Thus, a typical pharmaceutical composition for intravenous administration would be about 0.1 to 10 mg per patient per day. Dosages from 0.1 up to about 100 mg per patient per day may be used, particularly when the drug is administered to a secluded site and not into the blood stream, such as into a body cavity or into a lumen of an organ. Actual methods for preparing parenterally administrable compositions will be known or apparent to those skilled in the art and are described in more detail in such publications as Remington ' s Pharmaceutical Science, 15th ed. , Mack Publishing Company, Easton, Pennsylvania (1980) . The compositions containing the present rOnc molecules or the fusion proteins or a cocktail thereof (i.e., with other proteins) can be administered for therapeutic treatments. In therapeutic applications, compositions are administered to a patient suffering from a disease, in a cytotoxic amount, an amount sufficient to kill cells of interest. An amount adequate to accomplish this is defined as a "therapeutically effective dose." Amounts effective for this use will depend upon the severity of the disease and the general state of the patient's health. Single or multiple administrations of the compositions may be administered depending on the dosage and frequency as required and tolerated by the patient. In any event, the composition should provide a sufficient quantity of the proteins of this invention to effectively treat the patient.

All reagents except the DNA were combined and incubated at 95°C for 8 min to inactivate any residual proteinase K before the addition of the Taq DNA polymerase. PCR was performed for 40 cycles of denaturation at 94°C for l min, annealing for 2 min at 55°C and primer extension for 2 min at 72°C. Several pairs of primers yielded products of the expected size. The largest product (252 bp) was obtained using the forward primer encoding amino acid residues 15-23 (AG(GA)GATGT(GT)GATTG(TC)GATAA(CT)ATCATG) (SEQ ID NO:35) and the reverse primer encoding amino acid residues 90-98 (TGTGA(AG)AA(CT)CAGGC(AC)CC(TA)GT(GT)CA(CT)TTT) (SEQ ID NO:36). This fragment was subcloned into pCR™II by TA cloning and a clone carrying an insert of the appropriate size was directly sequenced and found to encode amino acid residues 16-98 of nOnc ("Rana 9") (SEQ ID N0:2) . The corresponding nucleic acid sequence is set out in SEQ ID NO:37. C. Plasmid Construction, Expression, Protein Purification and in Vi tro Assays. The N- and C-termini of nOnc were reconstructed using the PCR technique of splicing by overlap extension Horten et al . (1990) BioTechniques 8, 528-532 with amino acid residues 1-15 of nOnc or amino acid residues 1-21 of EDN at the N-terminal and amino acid residues 99-104 of nOnc at the C-terminal. The assembled genes were inserted between the Xbal and BamHI sites of the bacterial expression vector, pET-lld, Novagen, Madison, WI. All procedures were accomplished essentially as described in Newton et al . (1994) J Biol Chem. 269, 26739-26745. The plasmids were expressed in BL2KDE3) E. coli cells as recommended by the supplier, Novagen, Madison WI. The fusion proteins were isolated from inclusion bodies, denatured, renatured and dialyzed as described Newton et al. (1994) J Biol Chem. 269, 26739-26745 before being applied to a CM-Sephadex C-50 column, Pharmacia Biotech Inc., Piscataway, NJ. The proteins were eluted with a NaCl gradient (0-0.5M) in 20 mM Tris-HCl, pH 7.5, containing 10% glycerol. Final purification to >95% was achieved by size exclusion chromatography on Sephadex G-100 equilibrated and eluted with 5% formic acid. The proteins were pooled, concentrated by amicon ultrafiltration using a YM3 membrane (or lyophilized) , Amicon, Beverly, MA and dialyzed against 20 mM Tris-HCl, pH 7.5, containing 10% glycerol before being assayed Ribonuclease activity using high molecular weight RNA and tRNA was determined following published protocols, Newton et al . (1994) J Neurosci 14, 538-544 at 37°C through the formation of perchloric acid soluble nucleotides following published protocols (Newton et al . (1996) Biochem. 35:545- 553). With poly (A,C), UpG and poly U, ribonuclease activity was assayed spectrophotometrically according to DePrisco et al., and Libonati and Florida DePrisco et al . (1984) Biochimica et Biophysica Acta 788, 356-363, Libonati, M. & Floridi, A. (1969) European J. Biochem. 8, 81-87. Briefly, activity was assayed by measuring the increase in absorbance at 260 nm. Incubation mixtures (1 ml of 10 mM imidazole, 0.1 M NaCl, pH 6.5 or pH 7) contained substrate and appropriate amounts of enzyme solution at 25°C. The in vi tro translation assay, St. Clair et al . (1987) Proc Natl Acad Sci 84, 8330-8334, and the cell viability assays, Pearson et al . (1991) J Natl Cancer Inst 83, 1386-1391, using the (3- [4,5-Dimethylthiazol-2-yl-2,5-diphenyltetrazolium bromide; Thiazolyl blue] (MTT) Mossman, T. (1983) J". Immunol . Methods 65, 55-63 were performed as previously described. D. Cloning and Expression of [Met- (-1)1 rOnc and rOnc chimeras. Eight different oligonucleotide primers were designed to correspond to specific regions in the primary amino acid structure of nOnc, Ardelt et al . (1991) J. Biol . Chem. 256, 245-251 and amplification of Rana pipiens genomic DNA was carried out in a thermal cycler, as described above. A primer pair corresponding to amino acid residues 15 to 23 and 90 to 98 of nOnc, respectively, generated a 252 bp fragment. That PCR product, here denoted Rana clone 9, was cloned into pCR™II and sequence analysis confirmed that the PCR product encoded One (104 amino acids, total) from amino acid residue 16 to 98 (Fig. 1) . The entire recombinant One ("rOnc") gene (SEQ ID NO:38) was constructed by PCR extension and cloned into an expression vector using methodology previously described Newton et al. (1994) J Biol Chem. 269, 26739-26745. The amino and carboxyl termini of rOnc were completed by inserting the first 15 and last 6 amino acid residues of nOnc, respectively. The configuration of the semi-synthetic rOnc gene is depicted at the top of Fig. 2A. The primers were designed to overlap with the DNA sequence of the Rana clone 9 PCR product. The plasmid was expressed in BL21(DE3) E. coli and the recombinant protein was isolated from inclusion bodies as described in Newton et al . (1994) J Biol Chem. 269, 26739-26745 before being applied to a CM Sephadex C-50 column. Final purification to >95% was achieved by size exclusion chromatography. The rOnc obtained from the bacteria in this expression system contains an extra methionine at the amino terminal [Met-(-l)] (SEQ ID NO:39) in contrast to the authentic pyroglutamyl amino acid residue (<Glu-l) of the native protein (SEQ ID N0:1) . To humanize [Met-(-l)] rOnc while maintaining the alignment of the active site residues (Fig. 2B) , the N-terminal of Rana clone 9 was also reconstituted with oligonucleotides that coded for the first 21 amino acid residues of a human eosinophil RNase, EDN (Fig. 2B, rEDN (1 . 21) Onc) . PCR cloning can result in sequence errors. Indeed, the DNA sequence of the gene encoding EDN (1 . 21) Onc contained an A to G substitution resulting in a change from Asp to Gly at position 26 in the chimera (residue 20 in nOnc) and is designated as rEDN (1 _ 21) rOncG 26 -- n F ^-9 - 2B - Another plasmid containing encoding rEDN (1 _ 2l) rOnc was sequenced and found to have the correct DNA sequence. Since the mutation resulted in the substitution of a charged amino acid with a small neutral residue the mutant chimera was also expressed and characterized for activity. In addition, [Met- (-1) ]rOnc was mutated at position 20 from Asp to Gly (rOncGly 20 , Figs. 2A and B) . E. Ribonuclease activity of One, EDN, [Met- (-1)]rOnc and hybrid rOnc proteins. Both nOnc (Lin, J.J., et al . (1994) Biochem Biophys Res Co mun 204, 156-162) and EDN (Saxena et al . (1992) J. Biol . Chem. 267, 21982-21986) are potent inhibitors of in vi tro translation in the rabbit reticulocyte lysate by mechanisms that depend upon their respective nucleolytic activities. As depicted in Table 1, the addition of nOnc or EDN to a rabbit reticulocyte lysate caused the inhibition of protein synthesis as measured by the incorporation of [ 35 S]methionine into acid precipitable protein. Whereas both nOnc and EDN inhibited protein synthesis with IC 5θB of 0.2 and 1.3 ng/ml, respectively, [Met- (-1) ] rOnc, [Met- (-1) ]rOncG20, and rEDN (1 . 21) rOncG26 were considerably less potent (IC 50s 98, 28 and 28 ng/ml, respectively) . The least active RNase in this assay was rEDN (1 . 21) rOnc with an IC 50 of 1600 ng/ml. Placental ribonuclease inhibitor (PRI) binds tightly to EDN and inhibits its enzymatic activity, Sorrentino et al . (1992) J. Biol . Chem 267, 14859-14865, yet nOnc activity is very little affected by PRI, Wu, Y.N., et al . (1993) Journal of Biological Chemistry 268, 10686-10693 and Table 1, despite its homology to EDN and other members of the pancreatic RNase superfamily. In this regard, it is interesting that the activity of rEDN (1 . 21) rOnc is, like nOnc, barely affected by PRI while the hybrid RNase with the Gly mutation now behaves more like EDN in that its activity is significantly inhibited (21 fold) by PRI. The ribonuclease activity of these proteins was also assessed in assays using high and low molecular weight substrates. As shown in Table 2, EDN and nOnc have different substrate specificities consistent with previously published results (Ardelt et al . (1991) J " . Biol . Chem. 256, 245-251, Sorrentino et al . (1992) J. Biol . Chem 267, 14859-14865, Ardelt et al . (1994) Protein Sci 3, Suppl. 1, 137). Consistent with the results presented in Table 1, [Met- (-1) JrOnc (SEQ ID NO:39) and rEDN (1 . 21) rOnc were much less active with all of the substrates (non detectable or very little activity under the assay conditions employed) . Surprisingly, the Gly containing hybrid protein, manifested significant ribonuclease activity especially under conditions optimal for EDN enzymatic activity. EDN is more active at a neutral pH (Sorrentino et al . (1992) J. Biol . Chem 267, 14859-14865) and as seen in Table 2 there is a marked increase in EDN degradation of tRNA at pH 7.5 compared to pH 6 (42.3 fold) . Also, behaving like EDN, the Gly-containing hybrid increases in activity with a pH shift from 6 to 7.5 (21.7 fold) while nOnc loses activity at pH 7.5 consistent with its pH optimum that ranges from 6-6.5 (Ardelt et al . (1991) J. Biol . Chem. 256, 245-251, Ardelt et al . (1994) Protein Sci 3, Suppl. 1, 137) . The enhanced EDN-like activity of the Gly-containing hybrid protein is also evidenced by its behavior with poly(A,C) which is an excellent substrate for EDN. As seen in Table 2, only rEDN (1 . 21) r0ncG26 expresses almost 50% of the enzymatic activity of EDN with this substrate whereas the activity of the other RNases are negligible. Similar results were observed with poly(U) . In contrast, there was no detectable activity of rEDN or rEDN (1 . 21) rOncG26 with UpG, an optimal Onconase substrate (Ardelt et al . (1994) Protein Sci 3, Suppl. 1, 137). In summary, both [Met- (-1) ]rOnc and rEDN (1 . 21) rOnc are less enzymatically active than nOnc or rEDN. Although, rEDN (1 . 21) rOncG26 expresses significant EDN-like enzymatic activity when assayed using defined substrates and conditions optimal for EDN, it is not as active as EDN in any assay. This could result from an impaired enzyme substrate interaction or from the use of suboptimal assay conditions for this hybrid enzyme.

Each value is the average of two or more determinations. c [Met-(-l)]rOncG20 had no detectable activity. F. Inhibition of protein synthesis in four human tumor cell lines by RNases. The cytotoxic effect of [Met- (-1) ]rOnc and the two hybrid RNases were compared to rEDN and nOnc by determining cell viability using the MTT assay. As depicted in Fig. 3, nOnc decreased tumor cell viability in all four human tumor cell lines. At the concentrations shown, rEDN had no effect on the viability of any of the cell lines. In contrast to nOnc, [Met- (-1)]rOnc as well as [Met- (-1)]rOncG20 was consistently less cytotoxic in all four cell lines. Yet, rEDN (1 . 21) r0ncG26 was more cytotoxic than nOnc in ACHN, human renal carcinoma cells and equally cytotoxic in the MDA-MB-231 human breast carcinoma cell line. Although rEDN (1 . 21j rOncG26 was less active than nOnc in the SF-539 and HS 578T human glioma and breast cancer cell lines, respectively, it was still more active than [Met- (-1) ] rOnc or rEDN <:L _ 21) rOnc protein containing Asn at position 26. G. Structural Analysis of the hybrid RNases. Modeling the hybrid RNase was based on the alignment of the structures for One (Mosimann S.C., Ardelt W. , James M.N.G., (1994), Refined 1.7 A X-ray crystallographic structure of P-30 protein, an amphibian ribonuclease with anti-tumor activity (J Mol Biol 236, 1141-1153) and EDN (Mosimann S.C., Newton D.L., Youle R.J., James M. , X-ray crystallographic structure of recombinant eosinophil-derived neurotoxin at 1.83A resolution J Mol Biol) . This and subsequent alignments were carried out using ALIGN (Satow Y. , Cohen G.H., Padlan E.A., Davies D.R., (1986), J. Mol Biol 190, 593-604) . H. Modeling the structures of the hybrid RNases. The coordinates for One and EDN were superimposed on the basis of C α trace alignment. Residues in conserved zones, particularly in the active site, showed very little displacement when comparing both structures (global r.m.s.d. of 1.44 A for 90 C α atom pairs) . The hybrid protein was modeled by manual rebuilding and geometry regularization using TOM (Cambillau C, Horjales E., (1987), J " . Mol Graph 5, 174-177). Subsequently, the models for rEDN (1 . 21) rOnc and rEDN (1 . 21) rOncG26 were assigned an overall B-factor of 15 A 2 for all non-hydrogen atoms and independently subject to 300 cycles of positional energy minimization with the program XPLOR (Brunger A. (1992) XPLOR: a system for X-ray crystallography and NMR., New Haven: Yale University Press) . The minimization yielded virtually identical structures in both cases, the highest distance based on C a trace alignment being 0.44 for the C a of the mutated residue 26. The geometry quality of the final models were assessed with PROCHECK (Laskowski R.A., MacArthur M.W., Moss D.S., Thornton J.M. , (1993), J Appl Crystallogr 26 , 283-291) . The structural basis for the marked differences in activity between the Gly and Asp containing hybrid RNases are not obvious from modeling these proteins especially since residue 26 is distant from the active site. When the highly homologous structure of RNase A complexed with a pentanucleotide (Fontecilla-Camps J.C., deLorens R., leDu M.H., Cuchillo CM., (1994), J. Biol Chem 269, 21526-21531) was superimposed on the structure of the hybrid protein model, the nucleotide was observed also to be distant from the region of the mutation. However, the arrangement of the polynucleotide chain in the different RNases does not necessarily have to coincide. In the structure of EDN, a second sulfate ion was found in addition to the one in the active site (Mosimann S.C., Newton D.L., Youle R.J., James M. , X-ray crystallographic structure of recombinant eosinophil- derived neurotoxin at 1.83A resolution J Mol Biol) . This second sulfate is likely replacing a phosphate from the nucleotide to be cleaved, but no phosphate ion is located in the equivalent position in the RNase A-pentanucleotide complex. Moreover, one of the phosphates in this complex is forming a salt bridge with Lys-66, a residue which has no counterpart in One since it is located in a loop with a different topology in both molecules. Thus, whether the difference in enzymatic activity between the Asp and Gly mutants in the chimera is related to a change in the binding affinity for the substrate remains an open question. Although the structural basis for the difference in the activities of the two EDN-Onc hybrids is not clear, the EDN-like behavior of the rEDN {1 . 21) rOncG26 hybrid can likely be attributed to the configuration of the N-terminal region since both the pyroglutamic acid in nOnc and Lys-1 in EDN are located in the area of the active site (Mosimann S.C., Ardelt W. , James M.N.G. , (1994), Refined 1.7 A X-ray crystallographic structure of P-30 protein, an amphibian ribonuclease with anti-tumor activity J Mol Biol 236, 1141-1153; Mosimann S.C., Newton D.L., Youle R.J., James M. , X-ray crystallographic structure of recombinant eosinophil-derived neurotoxin at 1.83A resolution J Mol Biol) . In addition, the introduction of a Gly mutation in [Met- (-1) ]rOnc did not significantly affect enzymatic activity. The preference of U over C in the Bl subsite of RNase A has been related to the presence of a particular residue (Asp-83) (DelCardayre S.B., Raines R.T., (1995) , A residue to residue hydrogen bond mediates the nucleotide specificity of ribonuclease A J Mol Biol 252, 328- 336) . The corresponding residue in nOnc is also an aspartic acid (Asp-67) , while in EDN this position is occupied by a histidine (His-82) . EDN is more active toward poly (A,C), suggesting that it "prefers" C in the Bl subsite, possibly because it contains a histidine residue as opposed to the aspartic acid in nOnc and RNase A. Taken together, this could explain the decreased activity of the Gly containing hybrid relative to rEDN since, according to this hypothesis, the presence of the Asp residue contributed by the rOnc sequence would favor the binding of U over C. With regard to the difference in PRI inhibition, the superposition between the hybrid proteins and RNase A demonstrates that Asp-26 in the EDN-Onc chimeras is in the equivalent position to Asn-27 in RNase A that has been reported to be in contact with PRI (Kobe B., Deisenhofer J. , (1995), Nature 374, 183-186). In addition, Asp-24 in both chimeras is very close to this region. Thus, the accumulation of negative charges in this area could prevent binding by the inhibitor. If so, the substitution of Gly for Asp would decrease the negative charge and restore the binding capacity. Example II. rOnc-λntibody Fusion Proteins Additional rOnc-antibody and ligand proteins have been produced and are highly active. E6FB[Met- (-1) ]SerrOnc is an rOnc molecule having the nucleic acid sequence set out in SEQ ID NO:40 and the amino acid sequence set out in SEQ ID NO:41 and includes the Fv sequence from antibody E6, an anti- transferrin receptor antibody. See sequences for E6 at amino acid positions 1-237 in SEQ ID NO:4l. "FB" refers to a linker used to link the antibody and the rOnc portion of the molecule and is found at nucleic acid positions 712 through 750 in SEQ ID NO:40. This molecule includes a Ser at amino acid position 252 instead of a Glu. E6FB[Met- (-1)]GlurOnc refers to the sequence in SEQ ID NO:40. Similar hybrid molecules have been made. The nucleic acid and amino acid sequences for Met- NLS(signal peptide) -Gin-r0ncFBE6 are set out on SEQ ID N0S:42 and 43. Another E6/r0nc molecule is designated Met-Ser- r0ncA87FBE6 and is found on SEQ ID NOS:44 and 45. "A87" refers to the fact that an Ala occurs at amino acid position 87. Met-Ser-rOnc-Ang-FBE6 is set out on SEQ ID N0S:46 and 47. E6FBMet-Ser-r0nc is set out on SEQ ID NOS:48 and 49. Met-Glu-r0ncFBE6 is set out on SEQ ID NOS:50 and 51. Met-Ser-rOncFBE6 is set out on SEQ ID NOS:50 and 51, with the exception that Ser replaces Glu at amino acid position 2. MOC31 and MOC162 refer to anti-colon cancer antibodies directed against the 17-1-A pancarcinoma antigen which were obtained from Dr. Hennie Hoogenboom. The Fv region of these antibodies was fused to rOnc. The nucleic acid and amino acid sequences for MetSerrOnc A87 FBMOC31 are set out on SEQ ID NOS:52 and 53. The nucleic acid and amino acid sequences for MOC31FBMetSerrOnc are set out on SEQ ID NOS:54 and 55. The nucleic acid and amino acid sequences for MetSerrOncFBMOClδl are set out on SEQ ID NOS:56 and 57. The ligand, IL2 (interleukin 2) was recombinantly fused to rOnc as well. See SEQ ID NOS:58 and 59 for IL2FBMetSerrOnc. See SEQ ID NOS:60 and 61 for MetSerrOncFBIL2. Inhibition of protein synthesis in SF539 cells (which bear the transferrin receptor) was measured, as described above, for [Met- (-l)Ser]rOnc, E6FB[Met- (-l)Ser]rOnc; [Met- (-l)Ser]rOnc-AngFBE6 and [Met- (-l)Glu] rOncFBEδ constructs and compared with nOnc. The results are shown on Table 3. The three E6 constructs, in particular, had a very high level of activity -- up to 45 fold difference over the two non-E6 molecules. See also Figure 5. MetSerOncAng molecule was made corresponding to amino acids 1-107 of SEQ ID NO:47.
