Description: MAMMALIAN ADDITIONAL SEX COMBS (mammalian Asx) ACTS AS AN ONCOGENE Fiftlri nf thft Tnvpnrinn The invention relates to a gene, mammalian Additional Sex Combs (niammalian Asx), implicated in proliferative disorders, including malignancies, and in developmental processes. Rarlrgmiinri nf the. Tnwnrinn Cancer and malignancy therapies have included treatment with chemical toxins, radiation, and surgery. Genes known to be over-expressed or underexpressed in cancer are used for diagnosis of the disease and evaluation of a patient's progression with the disease and treatment. The study of transcription has provided information about cell differentiation: early in the development of a cell lineage, transcription factors direct development along a particular pathway by activating genes of a differentiated phenotype. Differentiation can involve not only changes in patterns of expressed genes, but also involve the maintenance of those new patterns. The genetic basis of niainmalian development, and the genetic link between development and cancer has not been fully elucidated. There is a need in the art for knowledge of the key genes underlying niammalian cancer, particularly those also implicated in normal mammalian developmental processes. .Summary nf thι> Invention In one embodiment of the invention an isolated mammalian Asx (mammalian Asx) polypeptide is provided.

Also provided by the present invention is a method of identifying modulators of mammalian Asx function comprising: contacting a mammalian cell which comprises an mammalian Asx gene or a reporter construct comprising an mammalian Asx promoter and a reporter gene with a test substance; quantitating transcription of mammalian Asx or the reporter gene in the presence and absence of the test substance, wherein a test substance which decreases transcription is a candidate drug for anti-neoplastic therapy. Detailed Ttesmptinn The inventors have discovered a gene, the mammalian Additional Sex Combs (mammalian Asx), that operates to regulate protein expression in mammals, particularly humans. Mammalian Asx may operate by controlling homeotic gene expression. Although the invention is not limited by any theory or mechanism of how the invention works, it is believed that control by this gene involves multiprotein complexes capable of negative regulation of transcription. The polypeptides of the invention according to SEQ ID NO: 2 and 4 contain various domains of the mammalian Asx gene. The nucleic acid molecules according to SEQ ID NO: 1 and 3 encode the mammalian Asx polypeptides and have been cloned from mammalian cells. The polynucleotide of SEQ ID NO: 1 encodes the polypeptide of SEQ ID NO: 2; the polynucleotide of SEQ ID NO: 3 encodes the polypeptide of SEQ ID NO: 4. Polypeptides comprising at least 6, 10, 18, 20, 30, 40, 50, 54, 60, 65, or 75 amino acids of mammalian Asx are useful as immunogens for raising antibodies and as competitors in immunoassays. They can also be used to purify antibodies. Nucleic acid molecules of at least 12, 13, 15, 20, 30, 40, or 50 contiguous nucleotides are useful as probes for use in diagnostic assays. Both human and murine Asx, and their coding sequences, are provided herein. There is sequence conservation between murine and human Asx. They are 84 % similar and 75 % identical at the amino acid level. Other mammalian Asx proteins and genes can be obtained by screening of cDNA libraries of a mammalian species with a probe derived from the murine or human sequences. Similar levels of identity and similarity are expected with other mammals. Such techniques are well known in the art, and can be employed by those of skill in the art. The domains of mammalian Asx protein which appear to be most conserved are those found in the following locations in the human protein. The conserved domains are at aa 250-356 and aa 1501-1536. In addition, there is a lysine rich putative nuclear translocation sequence from amino acid 2 to 11. The human Asx gene has been mapped to chromosome 20ql 1. This was accomplished by FISH mapping. Intriguingly, there are many chromosomal aberrations associated with a variety of cancers which also map to this chromosomal segment. Mammalian Asx is implicated in development, by contributing to the activation or repression of certain genes during development. Thus mammalian Asx can be used therapeutically to change the gene expression pattern and thus the phenotype of a cell. Thus, for example, mamrnalian Asx can be used to direct de-differentiation of a differentiated cell. Similarly, inhibition of mammalian Asx will direct a differentiated cell to become less differentiated, i.e. , to alter its pattern of gene expression. Proliferative indications for which an mammalian Asx-based therapeutic agent can be used include, restinosis, benign prostatic hyperplasia, uterine fibroids, retinopathy, psoriasis, keloids, arthritis, wound healing, and premalignant lesions including for example, intestinal polyps, cervical dysplasia, and myeloid dysplasia. Neoplasias that may be treatable with an mammalian Asx-based therapeutic agent, include, but are not limited to, carcinoma, colorectal adenocarcinoma, leukemia, Burkitt's lymphoma and melanoma. The coding region of mammalian Asx can be used for expression of mammalian Asx and for development of mammalian Asx variants for therapeutic applications. Mammalian Asx coding sequence can be used as a probe for diagnosis of disease or biological disorder where overexpression of mammalian Asx occurs, such as, for example, in cancers such as carcinoma, colorectal adenocarcinoma, lympha ~ cancer, promyelocytic leukemia, Burkitt's lymphoma, melanoma, and myeloma. l ..i 5' untranslated and 3' untranslated regions of mammalian Asx can also be used diagnostically to the same effect as the mammalian Asx coding sequence, for example, the 5' untranslated region can be isolated and used to probe tissue, for example, colon tissue, where colon carcinoma is suspected. Because mammalian Asx has been shown to be upregulated in colon carcinoma, probing with any portion of the mammalian Asx gene can identify the upregulation of mammalian Asx in the tissue, as an aid to making a diagnosis. Such diagnostic probes may also be used for continued monitoring of a diagnosed patient, for signs of improvement after and during treatment, and for indications of progression of the disease. Mammalian Asx genes can be cloned and isolated by probing genomic DNA with the coding region of mammalian Asx, or by probing genomic DNA with any probe-length piece (at least 12 nucleotides) of mammalian Asx DNA. A PI clone of genomic DNA containing ΛAsx (ATCC #98426, CMCC #4738) has been deposited at the American Type Culture Collection, Rockville, MD. The genomic DNA can be subcloned into a cloning vector, for example a cosmid vector, for sequencing and assembly of the entire gene sequence. The promoter region of mammalian Asx is useful for expression of mammalian Asx in a gene therapy protocol, and for further analysis of mammalian Asx gene function and regulatory control. Knowledge of promoter region sequences specific for binding transcriptional activators that activate the mammalian Asx promoter can facilitate improved expression of mammalian Asx for therapeutic purposes. The mammalian Asx promoter region may be useful for tissue specific expression of heterologous genes, such as, for treatment of colon carcinoma. The region immediately 5' of the coding region of mammalian Asx can be used, for example, as a diagnostic probe for cancer or a developmental disorder associated with aberrant mammalian Asx activity. The full length gene, or such non- coding regions of it as the promoter and the 5' or 3' untranslated regions can be isolated by probing genomic DNA with a probe comprising at least about 12 nucleotides of mammalian Asx cDNA, and retrieving a genomic sequence that hybridizes to one of these sequences. The 5' untranslated end and the promoter regions, for example, can be cloned by PCR cloning with random oligonucleotide and a 5' portion of the known coding sequence. The polypeptides of the invention can further be used to generate monoclonal or polyclonal antibodies. Monoclonal antibodies, are prepared using the method of Kohler and Milstein, as described in Nature (1975) 256: 495-96, or a modification thereof. Antibodies to mammalian Asx or fragments thereof, or fusion proteins thereof, either polyclonal or monoclonal, can be used therapeutically. They are desirably compatible with the host to be treated. For example, for treatment of humans, the antibodies can be human monoclonal antibodies or humanized antibodies, as the term is generally known in the art. Alternatively, single chain antibodies may be used for therapy. Antibodies may act to antagonize or inhibit the polypeptide activity of mammalian Asx, and are also useful in diagnosing a condition characterized by mammalian Asx expression or over-expression, such as, for example, a malignancy condition. Useful antibodies bind specifically to mammalian Asx but not to other human proteins. More preferred is the situation where the antibodies are human species niammalian Asx-specific. Expression of mammalian Asx can be accomplished by any expression system appropriate for the purpose and conditions presented. Some exemplary expression systems are listed below. Where mammalian Asx itself is used as a therapeutic, the polypeptide can be expressed and subsequently administered to a patient. Alternatively a gene encoding at least a functional portion of mammalian Asx can be administered to a patient for expression in the patient. Recombinant mammalian Asx may be used as a reagent for diagnostic methods for diagnosis of cancer or a developmental disorder. It may also be used as a therapeutic for inducing de-differentiation in a population of differentiated cells. Recombinant mammalian Asx can also be used to develop modulators of mammalian Asx for achieving a desired therapeutic effect. Construction and expression of any of the recombinant molecules of the invention can be accomplished by any expression system most appropriate for the task, including, for example, an expression system described below. Fτpτe5iRinn Systems Although the methodology described below is believed to contain sufficient details to enable one skilled in the art to practice the present invention, other constructs can be constructed and purified using standard recombinant DNA techniques as described in, for example, Sambrook et al.

Numerous baculoviral strains and variants and corresponding permissive insect host cells from hosts are described in Luckow et al , Bio/Technology (1988) 6: 47-55, Miller et al, in GENERIC ENGINEERING (Setlow, J.K. et al. eds.), Vol. 8 (Plenum Publishing, 1986), pp. 277-279, and Maeda et al , Nature, (1985) 315L 592-594. Mammalian expression can be accomplished as described in Dijkema et al, EMBO J. (1985) 4: 761, Gorman et al. , Proc. Natl Acad. Sci. USA (1982b) 79: 6777, Boshart et al, Cell (1985) 41: 521 and U.S. 4,399,216. Other features of mammalian expression can be facilitated as described in Ham and Wallace, Meth. Enz.

Constructs including an mammalian Asx coding sequence or constructs including coding sequences for modulators of mammalian Asx can be administered by a gene therapy protocol, either locally or systemically. These constructs can utilize viral or non-viral vectors and can be delivered in vivo or ex vivo or in vitro. Expression of such coding sequence can be driven by endogenous mammalian or heterologous promoters. Expression of the coding sequence in vivo can be either constitutive or regulated. Gene delivery vehicles (GDVs) are available for delivery of polynucleotides to cells, tissue, or to a the mammal for expression. For example, a polynucleotide sequence of the invention can be administered either locally or systemically in a GDV. These constructs can utilize viral or non-viral vector approaches in in vivo or ex vivo modality. Expression of such coding sequence can be induced using endogenous mammalian or heterologous promoters. Expression of the coding sequence in vivo can be either constitutive or regulated. The invention includes gene delivery vehicles capable of expressing the contemplated polynucleotides. The gene delivery vehicle is preferably a viral vector and, more preferably, a retroviral, adenoviral, adeno-associated viral (AAV), herpes viral, or alphavirus vectors. The viral vector can also be an astrovirus, coronavirus, orthomyxovirus, papovavirus, paramyxovirus, parvovirus, picornavirus, poxvirus, togavirus viral vector. See generally, Jolly, Cancer Gene Therapy 1:51-64 (1994); Kimura, Human Gene Therapy 5:845-852 (1994), Connelly, Human Gene Therapy 6:185-193 (1995), and Kaplitt, Nature Genetics 6: 148-153 (1994). Retroviral vectors are well known in the art and we contemplate that any retroviral gene therapy vector is employable in the invention, including B, C and D type retroviruses, xenotropic retroviruses (for example, NZB-X1, NZB-X2 and NZB9-1 (see O'Neill, J. Vir. 53:160, 1985) polytropic retroviruses (for example, MCF and MCF-MLV (see Kelly, J. Vir. 45:291, 1983), spumaviruses and lentiviruses. See RNA Tumor Viruses, Second Edition, Cold Spring Harbor Laboratory, 1985. Portions of the retroviral gene therapy vector may be derived from different retroviruses. For example, retroviral LTRs may be derived from a Murine Sarcoma Virus, a tRNA binding site from a Rous Sarcoma Virus, a packaging signal from a Murine Leukemia Virus, and an origin of second strand synthesis from an Avian Leukosis Virus. These recombinant retroviral vectors may be used to generate transduction competent retroviral vector particles by introducing them into appropriate packaging cell lines (see U.S. Serial No. 07/800,921, filed November 29, 1991). Retrovirus vectors can be constructed for site-specific integration into host cell DNA by incorporation of a chimeric integrase enzyme into the retroviral particle. See, U.S. Serial No. 08/445,466 filed May 22, 1995. It is preferable that the recombinant viral vector is a replication defective recombinant virus. Packaging cell lines suitable for use with the above-described retrovirus vectors are well known in the art, are readily prepared (see U.S. Serial No. 08/240,030, filed May 9, 1994; see also WO 92/05266), and can be used to create producer cell lines (also termed vector cell lines or "VCLs") for the production of recombinant vector particles. Preferably, the packaging cell lines are made from human parent cells (e.g. , HT1080 cells) or mink parent cell lines, which eliminates inactivation in human serum. Preferred retroviruses for the construction of retroviral gene therapy vectors include Avian Leukosis Virus, Bovine Leukemia, Virus, Murine Leukemia Virus, Mink-Cell Focus-Inducing Virus, Murine Sarcoma Virus, Reticuioendotheliosis Virus and Rous Sarcoma Virus. Particularly preferred Murine Leukemia Viruses include 4070A and 1504A (Hartley and Rowe, J. Virol. 19:19-25, 1976), Abelson (ATCC No. VR-999), Friend (ATCC No. VR-245), Graffi, Gross (ATCC No. VR-590), Kirsten, Harvey Sarcoma Virus and Rauscher (ATCC No. VR-998) and Moloney Murine Leuicemia Virus (ATCC No. VR-190). Such retroviruses may be obtained from depositories or collections such as the American Type Culture Collection ("ATCC") in Rockville, Maryland or isolated from known sources using commonly available techniques.

Most preferred AAV vectors comprise the two AAV inverted terminal repeats in which the native D-sequences are modified by substitution of nucleotides, such that at least 5 native nucleotides and up to 18 native nucleotides, preferably at least 10 native nucleotides up to 18 native nucleotides, most preferably 10 native nucleotides are retained and the remaining nucleotides of the D-sequence are deleted or replaced with non-native nucleotides. The native D-sequences of the AAV inverted terminal repeats are sequences of 20 consecutive nucleotides in each AAV inverted terminal repeat (i.e., there is one sequence at each end) which are not involved in HP formation. The non-native replacement nucleotide may be any nucleotide other than the nucleotide found in the native D-sequence in the same position. Other employable exemplary AAV vectors are pWP-19, pWN-1 , both of which are disclosed in Nahreini, Gene 124:257-262 (1993). Another example of such an AAV vector is psub201. See Samulski, J.

Soc. Exp. Biol. Med. 121:190 (1966). Delivery of the compositions of this invention into ceUs is not timited to the above mentioned viral vectors. Other deUvery methods and media may be employed such as, for example, nucldc add expression vectors, polycationic condensed DNA linked or unlinked to killed adenovirus alone, for example see U.S. Serial No. 08/366,787, filed December 30, 1994, and Curid, Hum Gene Ther 3: 147-154 (1992) Ugand linked DNA, for example, see Wu, J. Biol. Chem. 264:16985-16987 (1989), eukaryotic ceU deUvery vehicles ceUs, for example see U.S. Serial No. 08/240,030, filed May 9, 1994, and U.S. Serial No. 08/404,796, deposition of photopolymerized hydrogel materials, hand-held gene transfer particle gun, as described in U.S. Patent No. 5,149,655, ionizing radiation as described in U.S. Patent No. 5,206,152 and in PCT Patent Publication No. WO 92/11033, nucldc charge neutralization or fusion with ceU membranes. Additional approaches are described in PhiUp, Mol. CeU. Biol. 14:2411-2418 (1994) and in Woffendin, Proc. Natl. Acad. Sci. 91:1581-585 (1994). Particle mediated gene transfer may be employed, for example see U.S. provisional application No. 60/023,867. Briefly, the sequence can be inserted into conventional vectors that contain conventional control sequences for high level expression, and then be incubated with synthetic gene transfer molecules such as polymeric DNA-binding cations like polylysine, protamine, and albumin, linked to ceU targeting tigands such as asialoorosomucoid, as described in Wu and Wu, J. Biol. Chem. 262:4429-4432 (1987), insulin as described in Hucked, Biochem. Pharmacol. 40:253-263 (1990), galactose as described in Plank, Bioconjugate Chem 3:533-539 (1992), lactose or transferrin. Naked DNA may also be employed. Exemplary naked DNA introduction methods are described in PCT Patent PubUcation No. WO 90/11092 and U.S. Patent No. 5,580,859. Uptake efficiency may be improved using biodegradable latex beads. DNA coated latex beads are efficiently transported into ceUs after endocytosis initiation by the beads. The method may be improved further by treatment of the beads to increase hydrophobidty and thereby faciUtate disruption of the endosome and release of the DNA into the cytoplasm. Liposomes that can act as gene deUvery vehicles are described in U.S. Patent No. 5,422,120, PCT Patent PubUcation Nos. WO 95/13796, WO 94/23697, and WO 91/144445, and EP No. 524,968. As described in co-owned U.S. provisional application No. 60/023,867, on non-viral deUvery, the nucleic acid sequences can be inserted into conventional vectors that contain conventional control sequences for high level expression, and then be incubated with synthetic gene transfer molecules such as polymeric DNA-binding cations like polylysine, protamine, and albumin, linked to ceU targeting Ugands such as asialoorosomucoid, insulin, galactose, lactose, or transferrin. Other deUvery systems include the use of Uposomes to encapsulate DNA comprising the gene under the control of a variety of tissue-specific or ubiquitously-active promoters. Further non-viral deUvery suitable for use includes mechanical deUvery systems such as the approach described in Woffendin et al., Proc. Natl. Acad. Sci. USA 91(24):11581-U585 (1994). Moreover, the coding sequence and the product of expression of such can be deUvered through deposition of photopolymerized hydrogel materials. Other conventional methods for gene deUvery that can be used for deUvery of the coding sequence include, for example, use of hand-hdd gene transfer particle gun, as described in U.S. Patent No. 5,149,655; use of ionizing radiation for activating transferred gene, as described in U.S. Patent No. 5,206,152 and PCT Patent PubUcation No. WO 92/11033. Exemplary Uposome and polycationic gene deUvery vehicles are those described in U.S. Patent Nos. 5,422,120 and 4,762,915, in PCT Patent PubUcation Nos. WO 95/13796, WO 94/23697, and WO 91/14445, in EP No. 524,968 and in Stryer, Biochemistry, pages 236-240 (1975) W.H. Freeman, San Frandsco, Szoka, Biochem. Biophys. Acta. 600:1 (1980); Bayer, Biochem. Biophys. Acta. 550:464 (1979); Rivnay, Meth. Enzymol. 149:119 (1987); Wang, Proc. Natl. Acad. Sci. 84:7851 (1987); and Plant, Anal. Biochem. 176:420 (1989). Test compounds can be tested as candidate modulators by testing the abitity to increase or decrease the expression of mammalian Asx. The candidate modulators can be derived from any of the various possible sources of candidates, such as for example, libraries of peptides, peptoids, smaU molecules, polypeptides, antibodies, polynucleotides, smaU molecules, antisense molecules, ribozymes, cRNA, cDNA, polypeptides presented by phage display. Described below are some exemplary and possible sources of candidates, including synthesized Ubraries of peptides, peptoids, and smaU molecules. The exemplary expression systems can be used to generate cRNA or cDNA Ubraries that can also be screened for the ability to modulate mammaUan Asx activity or expression. Candidate molecules screened for the abitity to agonize mammaUan Asx expression or activity may be useful for inducing differentiation in a population of progenitor ceUs. SmaU molecules can be screened for the abiUty to either affect mammaUan Asx expression or affect mammaUan Asx function by enhancing or interfering in mammaUan Asx's abiUty to interact with other molecules that mammaUan Asx normaUy interacts with in mammaUan Asx's normal function. MammaUan Asx peptide modulators are screened using any available method. The assay conditions ideaUy should resemble the conditions under which the mammaUan Asx modulation is exhibited in vivo, that is, under physiologic pH, temperature, ionic strength, etc. Suitable antagonists will exhibit strong inhibition of mammaUan Asx expression or activity at concentrations that do not cause toxic side effects in the subject. A further alternative agent that can be used herein as a modulator of mammaUan Asx is a smaU molecule antagonist. SmaU molecules can be designed and screened from a pool of synthetic candidates for abiUty to modulate mammaUan Asx. There exist a wide variety of smaU molecules, including peptide analogs and derivatives, that can act as inhibitors of proteins and polypeptides. Libraries of these molecules can be screened for those compounds that inhibit the activity or expression of mammaUan Asx. Similarly, ribozymes can be screened in assays appropriate for ribozymes, taking into account the special biological or biochemical nature of ribozymes. Assays for affecting mammaUan Asx expression can measure mammaUan Asx message or protein directly, or can measure a reporter gene expression which is under the control of an mammaUan Asx promoter and/or 5' untranslated region (UTR). MammaUan Asx or a modulator of mammaUan Asx can be administered to a patient exhibiting a condition characterized by abnormal ceU proUferation, in which aberrant mammaUan Asx gene expression is impUcated, particularly excessive mammaUan Asx activity, or excessive activity controlled or induced by mammalian Asx activity. The modulator can be incorporated into a pharmaceutical composition that includes a pharmaceutically acceptable carrier for the modulator. Suitable carriers may be large, slowly metabolized macromolecules such as proteins, polysaccharides, polylactic acids, polyglycoUc adds, polymeric amino adds, amino add copolymers, and inactive virus particles. Such carriers are weU known to those of ordinary skLU in the art. PharmaceuticaUy acceptable salts can be used therein, for example, mineral acid salts such as hydrochlorides, hydrobromides, phosphates, sulfates, and the like; and the salts of organic acids such as acetates, propionates, malonates, benzoates, and the Like. A thorough discussion of pharmaceuticaUy acceptable excipients is available in REMINGTON'S PHARMACEUΗCAL SCIENCES (Mack Pub. Co., NJ. 1991). PharmaceuticaUy acceptable carriers in therapeutic compositions may contain tiquids such as water, saline, glycerol and ethanol. Additionally, auxiliary substances, such as wetting or emulsifying agents, pH buffering substances, and the like, may be present in such vehicles. TypicaUy, the therapeutic compositions are prepared as injectables, either as Uquid solutions or suspensions; sotid forms suitable for solution in, or suspension in, Uquid vehicles prior to injection may also be prepared. Liposomes are included within the definition of a pharmaceuticaUy acceptable carrier. The term "Uposomes" refers to, for example, the Uposome compositions described in U.S. Patent NO: 5,422,120, WO 95/13796, WO 94/23697, WO 91/14445 and EP 524,968 Bl. Liposomes may be pharmaceutical carriers for the peptides, polypeptides or polynucleotides of the invention, or for combination of these therapeutics. Any therapeutic of the invention, including, for example, polynucleotides for expression in the patient, or ribozymes or antisense oUgonucleotide, can be formulated into an enteric coated tablet or gel capsule according to known methods in the art. These are described in the foUowing patents: US 4,853,230, EP 225,189, AU 9,224,296, AU 9,230,801, and WO 92144,52. Such a capsule is administered oraUy to be targeted to the jejunum. At 1 to 4 days foUowing oral administration expression of the polypeptide, or inhibition of expression by, for example a ribozyme or an antisense oUgonucleotide, is measured in the plasma and blood, for example by antibodies to the expressed or non-expressed proteins. Adniinistration of a therapeutic agent of the invention, including for example an mammaUan Asx modulator, includes administering a therapeutically effective dose of the therapeutic agent by a means considered or empiricaUy deduced to be effective for inducing the desired effect in the patient. Both the dose and the administration means can be determined based on the specific quaUties of the therapeutic, the condition of the patient, the progression of the disease, and other relevant factors. Administration of the therapeutic agents of the invention can include, local or systemic administration, including injection, oral administration, particle gun or catheterized administration, and topical administration. The therapeutics of the invention can be administered in a therapeuticaUy effective dosage and amount, in the process of a therapeuticaUy effective protocol for treatment of the patient. The initial and any subsequent dosages administered wiU depend upon the patient's age, weight, condition, and the disease, disorder or biological condition being treated. Depending on the therapeutic, the dosage and protocol for administration will vary, and the dosage wiU also depend on the method of administration selected, for example, local or systemic adniinistration. For polypeptide therapeutics, for example, a dominant negative mammaUan Asx polypeptide or a polypeptide modulator of mammaUan Asx, the dosage can be in the range of about 5 μg to about 50 μg/kg of patient body weight, also about 50 μg to about 5 mg/kg, also about 100 μg to about 500 μg/kg of patient body weight, and about 200 to about 250 μg/kg. For polynucleotide therapeutics, depending on the expression of the polynucleotide in the patient, for tissue targeted adniinistration, vectors containing expressible constructs including mammaUan Asx coding sequences or modulator coding sequences, or non-coding sequences can be administered in a range of about 100 ng to about 200 mg of DNA for local administration in a gene therapy protocol, also about 500 ng to about 50 mg, also about 1 ug to about 2 mg of DNA, about 5 ug of DNA to about 500 ug of DNA, and about 20 ug to about 100 ug during a local administration in a gene therapy protocol, and for example, a dosage of about 500 ug, per injection or administration. Non-coding sequences that act by a catalytic mechanism, for example, catalyticaUy active ribozymes may require lower doses than non-coding sequences that are hdd to the restrictions of stoichiometry, as in the case of, for example, antisense molecules, although expression Umitations of the ribozymes may again raise the dosage requirements of ribozymes being expressed in vivo in order that they achieve efficacy in the patient. Factors such as method of action and efficacy of transformation and expression are therefore considerations that wϋl effect the dosage required for ultimate efficacy for DNA and nucldc adds. Where greater expression is desired, over a larger area of tissue, larger amounts of DNA or the same amounts readministered in a successive protocol of administrations, or several administrations to different adjacent or close tissue portions of for example, a tumor site, may be required to effect a positive therapeutic outcome. For administration of smaU molecule modulators of mammaUan Asx polypeptide activity, depending on the potency of the small molecule, the dosage may vary. For a very potent inhibitor, microgram (μg) amounts per kilogram of patient may be sufficient, for example, in the range of about 1 μg/kg to about 500 mg/kg of patient weight, and about 100 μg/kg to about 5 mg/kg, and about 1 μg/kg to about 50 μg/kg, and, for example, about 10 ug/kg. For administration of peptides and peptoids the potency also affects the dosage, and may be in the range of about 1 μg/kg to about 500 mg/kg of patient weight, and about 100 μg/kg to about 5 mg/kg, and about 1 μg/kg to about 50 μg/kg, and a usual dose might be about 10 ug/kg. In aU cases, routine experimentation in clinical trials wiU determine specific ranges for optimal therapeutic effect, for each therapeutic, each administrative protocol, and administration to specific patients wiU also be adjusted to within effective and safe ranges depending on the patient condition and responsiveness to initial administrations. Diagnostic assays for Asx sequence can be appUed to cancers demonstrating upregulationof Asx transcript, particularly to cancers of lymphoma, melanoma, and adenocarcinoma. Such diagnostics can be accompUshed using any portion of the Asx gene, including the 3' and 5' untranslated regions of the gene, to probe patient tissues • to determine an upregulation of an Asx transcript. Administration of a therapeutic agent for a condition in which increased expression of mammaUan Asx is impUcated, for example, in the case of promyelocytic leukemia, chronic myelogenous leukemia, lymphoblastic leukemia, Burkitt's lymphoma, colorectal adenocarcinoma, melanoma, and lymphoma, can be preceded by diagnosis of the condition using an mammaUan Asx probe, generated from any portion of the mammaUan Asx gene, and probing the suspect tissue. bDNA technology using bDNA probes to mammaUan Asx gene sequences or mammaUan Asx mRNA sequences may be used, as described in WO 92/02526 or U.S. 5,451,503, and U.S. 4,775,619. Once diagnosis is complete, treatment can include administration of mammaUan Asx polynucleotides or anti-sense oUgonucleotide by a gene therapy protocol, or by adniinistration by other means including local or systemic administration, of an mammaUan Asx modulator, for example an mammaUan Asx- spedfic ribozyme, or a geneticaUy altered mammaUan Asx variant, for example a dominant negative mammaUan Asx, or a smaU molecule or peptide or peptoid mammaUan Asx modulator, or any combination of these potential therapeutics. The patient can be subsequently monitored by periodic reprobing of the affected tissue with an mammaUan Asx probe. Even in cancers where mammaUan Asx mutations are not impUcated, mammaUan Asx downregulation or inhibition of mammaUan Asx function may have therapeutic appUcation. In these cancers, decreasing mammaUan Asx expression or inhibiting mammaUan Asx function may help to suppress the tumors. Similarly, even in tumors where mammaUan Asx expression is not aberrant, effecting mammaUan Asx downregulation or diminution of mammaUan Asx activity may suppress metastases. Further objects, features, and advantages of the present invention wiU become apparent from the detatied description. It should be understood, however, that the detatied description, while indicating preferred embodiments of the invention, is given by way of iUustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description. Definitions A "nucleic acid molecule" or a "polynucleotide," as used herein, refers to either RNA or DNA molecule that encodes a specific amino acid sequence or its complementary strand. Nucleic acid molecules may also be non-coding sequences, for example, a ribozyme, an antisense oUgonucleotide, or an untranslated portion of a gene. A "coding sequence" as used herein, refers to either RNA or DNA that encodes a specific amino add sequence or its complementary strand. A polynucleotide may include, for example, an antisense oUgonucleotide, or a ribozyme, and may also include such items as a 3' or 5' untranslated region of a gene, or an intron of a gene, or other region of a gene that does not make up the coding region of the gene. The DNA or RNA may be single stranded or double stranded. Synthetic nucleic adds or synthetic polynucleotides can be chemicaUy synthesized nucleic acid sequences, and may also be modified with chemical moieties to render the molecule resistant to degradation. Synthetic nucleic acids can be ribozymes or antisense molecules, for example. Modifications to synthetic nucleic acid molecules include nucleic add monomers or derivative or modifications thereof, including chemical moieties. For example, phosphothioates can be used for the modification. A polynucleotide derivative can include, for example, such polynucleotides as branched DNA (bDNA). A polynucleotide can be a synthetic or recombinant polynucleotide, and can be generated, for example, by polymerase chain reaction (PCR) amptification, or recombinant expression of complementary DNA or RNA, or by chemical synthesis. MammaUan Asx polynucleotides share at least 70 % and preferably at least 75, 80, 85, 90, or 95 % identity with either mouse or human ΛAsx sequences. These can be obtained, inter alia, by hybridization of mouse or human Asx probes under conditions of stringent hybridization. Encompassed within the definition of mammaUan, human, and mouse Asx are sequences which contain aUetic variants, as weU as sequences which differ due to the degeneracy of the genetic code. The term "functional portion of as used herein refers to a portion of an mammaUan Asx wild-type molecule which retains at least 50% of activity of mammaUan Asx. It also encompasses a portion of an mammaUan Asx gene having single base substitutions, deletions, or insertions that have no adverse effect on the activity of the molecule. Truncations of mammaUan Asx, fragments of Asx, and combinations of fragments of Asx, which retain at least 50% activity are contemplated. Such portions of hAsx may also be fused to other proteins, such as in a gene fusion. The term "functional" as used herein refers to a gene functional in cancer or differentiation. A molecule is functional if its expression causes, directly or indirectly, an event specificaUy associated with differentiation, mitosis, oncogenesis, metastasis, or the like. The term "modulate" as used herein refers to the abiUty of a molecule to alter the function or expression of another molecule. Thus, modulate could mean, for example, inhibit, antagonize, agonize, upregulate, downregulate, induce, or suppress. A modulator has the capability of altering function of its target. Such alteration can be accompUshed at any stage of the transcription, translation, expression or function of the protein, so that, for example, modulation of mammaUan Asx can be accompUshed by modulation of the DNA, RNA, and protein products of the gene. It assumed that modulation of the function of the target, for example, mammaUan Asx, will in turn modulate, alter, or affect the function or pathways leading to a function of genes and proteins that would otherwise associate, and interact, or respond to, mammaUan Asx. A "maUgnancy" includes any proUferative disorder in which the ceUs protiferating are ultimately harmful to the host. Cancer is an example of a proUferative disorder that manifests a maUgnancy. Neoplasia is the state of ceUs which experience uncontroUed ceU growth, whether or not maUgnant. The term "regulatory sequence" as used herein refers to a nucleic acid sequence encoding one or more elements that are capable of affecting or effecting expression of a gene sequence, including transcription or translation thereof, when the gene sequence is placed in such a position as to subject it to the control thereof. Such a regulatory sequence can be, for example, a minimal promoter sequence, a complete promoter sequence, an enhancer sequence, an upstream activation sequence ("UAS"), an operator sequence, a downstream termination sequence, a polyadenylation sequence, an optimal 5' leader sequence to optimize initiation of translation, and a Shine-Dalgarno sequence. Alternatively, the regulatory sequence can contain a combination enhancer/promoter element. The regulatory sequence that is appropriate for expression of the present construct differs depending upon the host system in which the construct is to be expressed. Selection of the appropriate regulatory sequences for use herein is within the capabiUty of one skilled in the art. For example, in prokaryotes, such a regulatory sequence can include one or more of a promoter sequence, a ribosomal binding site, and a transcription termination sequence. In eukaryotes, for example, such a sequence can include one or more of a promoter sequence and/or a transcription termination sequence. If any necessary component of a regulatory sequence that is needed for expression is lacking in the polynucleotide construct, such a component can be suppUed by a vector into which the polynucleotide construct can be inserted for expression. Regulatory sequences suitable for use herein may be derived from any source including a prokaryotic source, an eukaryotic source, a virus, a viral vector, a bacteriophage or from a linear or circular plasmid. An example of a regulatory sequence is the human immunodeficiency virus ("HIV") promoter that is located in the U3 and R region of the HIV long teπrdnal repeat ("LTR"). Alternatively, the regulatory sequence herein can be a synthetic sequence, for example, one made by combining the UAS of one gene with the remainder of a requisite promoter from another gene, such as the GADP/ADH2 hybrid promoter. The terms "protein", "polypeptide", "polypeptide derivatives" and modifications and variants thereof refer herein to the expression product of a polynucleotide construct of the invention as defined above. The terms further include truncations, variants, aUeles, analogs and derivatives thereof. Unless specificaUy mentioned otherwise, such mammaUan Asx polypeptides possess one or more of the bioactivities of the mammaUan Asx protein, such as those discovered herein. This term is not Umited to a specific length of the product of the mammaUan Asx gene. Thus, polypeptides that are identical or contain at least 70 % , and more preferably 75 % , and most preferably 80, 85, 90, or 95 % identity with the mammaUan Asx protein or the mature mammaUan Asx protein, wherever derived, from human or nonhuman sources are included within this definition of the mammaUan Asx polypeptide. Also included, therefore, are aUeles and variants of the product of the mammaUan Asx gene that contain amino acid substitutions, deletions, or insertions. The amino acid substitutions can be conservative amino acid substitutions or substitutions to eUminate non-essential amino acid residues such as to alter a glycosylation site, a phosphorylation site, an acetylation site, or to alter the folding pattern by altering the position of the cysteine residue that is not necessary for function, etc. Conservative amino acid substitutions are those that preserve the general charge, hydrophobicity/hydrophiUdty and/or steric bulk of the amino acid substituted, for example, substitutions between the members of the foUowing groups are conservative substitutions: Gly/ Ala, Val/Ile/Leu, Asp/Glu, Lys/ Arg, Asn/Gln, Ser/Thr/Cys and Phe/Trp/Tyr. Analogs include peptides having one or more peptide mimics, also known as peptoids, that possess mammaUan Asx protein-like activity. Included within the definition are, for example, polypeptides containing one or more analogs of an amino acid (including, for example, unnatural amino acids, etc.), polypeptides with substituted linkages, as weU as other modifications known in the art, both naturaUy occurring and nonnaturaUy occurring. The term "mammaUan Asx" also may include post-expression modifications of the polypeptide, for example, glycosylations, acetylations, phosphorylations, myrstylations, farnesylations, palmitoylations and the like. The term "polypeptide fragment" as used herein refers to a polypeptide sequence that does not encode the full length of a protein but that is identical to a region of the protein. The fragment is designed to retain the functional aspect of the region of the polypeptide from which it is derived. Two fragments can cooperate to provide function. Two distinct polypeptide fragments of the same gene may represent expressed sptice variants of that gene, although functionaUty and expression of the polypeptide sptice variant products may occur in similar biological conditions, and may be related, at least in part, in function. The term "derivative" as used herein in reference to a polypeptide or a polynucleotide means a polypeptide or polynucleotide that retains at least 50% of the functionaUty of the polypeptide or polynucleotide to which it is a derivative. They may be variously modified by nucleotide or amino acid deletions, substitutions, insertions or inversions by, for example, site directed mutagenesis of the underlying nucleic acid molecules. Derivatives of a polypeptide or polynucleotide may also be fragments or combinations of fragments thereof. In any case, a derivative, or a fragment, retains at least some, and preferably aU of the function of the polypeptide from which it is derived. An "isolated polypeptide" or "isolated polynucleotide" as used herein refers to a polypeptide or polynucleotide, respectively, produced in vivo or in vitro in an environment manipulated by humans using state of the art techniques of molecular biology, biochemistry and gene therapy. For example, an isolated polypeptide can be produced in a cell free system by automated peptide or polypeptide synthesis, in heterologous host ceUs transformed with the nucleic add sequence encoding the polypeptide and regulatory sequences for expression in the host ceUs, and in an animal into which the coding sequence of the polypeptide has been introduced for expression in the animal. A polypeptide or polynucleotide is "isolated" for purposes herein to the extent that it is not present in its natural state inside a ceU as a product of nature. For example, such isolated polypeptides or polynucleotides can be 10% pure, 20% pure, or a higher degree of purity, such as 50% , 75 % , 85 % , or 90% . The term "condition" as used herein in terms of "a patient having a condition" refers to a particular state of molecular and ceUular systems in a biological context. A biological context includes any organism considered to have life, and for the purposes of this invention includes but is not timited the foUowing organisms or groups: animals, mammals, humans, and vertebrates. A biological condition can include, for example, a disease or a medical condition that may or may not be characterized by identifiable symptoms or indicators. A "condition characterized by abnormal ceU proUferation" is most likely a cancer condition, but may also be a condition arising in the development of an organism. The term "modulator" as used herein describes any moiety capable of changing the endogenous activity or a polypeptide. Modulatory activities can include, for example, modulation at the level of transcription, translation, expression, secretion, or modulation of polypeptide activity inside or outside a cell. Modulation can include, for example, inhibition, antagonism, and agonism, and modulation can include, for example, modulation of upstream or downstream effects that effect the ultimate activities in a pathway, or modulation of the configuration of a polypeptide such that its activity is altered. Modulation can be transitory or permanent, and may be a dose dependent effect. The term "inhibitor" for use herein can be any inhibitor of a polypeptide activity. The category includes but is not Umited to any of the herein described antagonists of mammaUan Asx. The inhibitor of mammaUan Asx can be an antibody- based mammaUan Asx antagonist, or a polypeptide fragment thereof, a peptide mammaUan Asx antagonist, a peptoid mammaUan Asx antagonist, or a smaU molecule mammaUan Asx antagonist. The polypeptide inhibitor can be one screened from a cDNA, cRNA, or phage display tibrary of polypeptides. The inhibitor can be a polynucleotide, such as, for example a ribozyme or an antisense oUgonucleotide, or can be derivatives of these. It is expected that some inhibitors wiU act at transcription, some at translation, and some on the mature protein. However, the use and appropriateness of such inhibitors of mammaUan Asx for the purposes of the invention are not Umited to any theories of mechanism of action of the inhibitor. It is sufficient for purposes of the invention that an inhibitor inhibit the activity of mammaUan Asx. The term "antagonist" as used herein refers to a molecule that inhibits or blocks the activity of a polypeptide, either by blocking the polypeptide itself, or by causing a reduced expression of the polypeptide by either blocking transcription of the gene encoding the polypeptide, or by interfering with or destroying a transcription or translation product of the gene. An antagonist may be, for example, a smaU molecule, peptide, peptoid, polypeptide, or polynucleotide. The polynucleotide may be, for example, a ribozyme, an antisense oUgonucleotide, or a coding sequence. The term "agonist" as used herein refers to a molecule that mimics the activity of the target polypeptide. For example, in the case of mammaUan Asx, an agonist could mimic the transcriptional negative regulation capability of mammaUan Asx. An agonist may be, for example a smaU molecule, peptide, peptoid, polypeptide, or polynucleotide. The term "pharmaceutical composition" refers to a composition for administration of a therapeutic agent, such as antibodies or a polypeptide, or inhibitors or genes and other therapeutic agents Usted herein, in vivo, and refers to any pharmaceutical carrier that does not itself induce the production of antibodies harmful to the individual receiving the composition, and which may be administered without undue toxicity. The term "an effective amount" as used herein refers to an amount that is effective to induce a desired effect. Where the effect is a therapeutic effect, the effective amount is that amount that wiU accompUsh a therapeutic goal, for example, tumor regression, tumor marker reduction, or a positive indication from other indicia of cancer that indicates a reduction or growth slowing of cancer ceUs. Where the therapeutic agent is, for example, an antagonist of mammaUan Asx, the effective amount of the antagonist would be an amount that antagonizes mammaUan Asx activity among a population of ceUs. The amount that is effective depends in part upon the indicia selected for determining effectiveness, and depends upon the effect sought. An administration of a therapeutic agent of the invention includes adrninistration of a therapeuticaUy effective amount of the agent of the invention. The term "therapeuticaUy effective amount" as used herein refers to an amount of a therapeutic agent to treat or prevent a condition treatable by administration of a composition of the invention. That amount is the amount sufficient to exhibit a detectable therapeutic or preventative or ameUorative effect. The effect may include, for example, treatment or prevention of the conditions Usted herein. The predse effective amount for a subject wtil depend upon the subject's size and health, the nature and extent of the condition being treated, recommendations of the treating physician, and the therapeutics or combination of therapeutics selected for adrninistration. Thus, it is not useful to specify an exact effective amount in advance. However, the effective amount for a given situation can be determined by routine experimentation. Administration can include administration of a polypeptide, and causing the polypeptide to be expressed in an animal by administration of the polynucleotide encoding the polypeptide. A "recombinant vector" herein refers to any vector for transfer or expression of the polynucleotides herein in a ceU, including, for example, viral vectors, non-viral vectors, plasmid vectors and vectors derived from the regulatory sequences of heterologous hosts and expression systems. The term "in vivo administration" refers to administration to a mammal of a polynucleotide encoding a polypeptide for expression in the mammal. In particular, direct in vivo adrninistration involves transfecting a mammal's ceU with a coding sequence without removing the ceU from the mammal. Thus, direct in vivo adrninistration may include direct injection of the DNA encoding the polypeptide of interest in the region afflicted by the maUgnancy or proUferative disorder, resulting in expression in the mammal's ceUs. The term "ex vivo administration" refers to transfecting a ceU, for example, a cell from a population of ceUs that are maUgnant or proUferating, after the cell is removed from the mammal. After transfection the ceU is then replaced in the mammal. Ex vivo administration can be accompUshed by removing ceUs from a mammal, optionaUy selecting for cells to transform, (i.e. ceUs that are maUgnant or proUferating) rendering the selected ceUs incapable of repUcation, transforming the selected ceUs with a polynucleotide encoding a gene for expression, (i.e. mammaUan Asx), including also a regulatory region for facilitating the expression, and placing the transformed cells back into the mammal for expression of the mammaUan Asx. "BiologicaUy active" refers to a molecule that retains a specific activity. A biologicaUy active mammaUan Asx polypeptide, for example, retains the activity including for example the control of a homeotic gene or group of homeotic genes. "MammaUan ceU" as used herein refers to a subset of eukaryotic ceUs useful in the invention as host ceUs, and includes human ceUs, and animal cells such as those from dogs, cats, cattle, horses, rabbits, mice, goats, pigs, etc. The cells used can be geneticaUy unaltered or can be geneticaUy altered, for example, by transformation with appropriate expression vectors, marker genes, and the like. MammaUan cells suitable for the method of the invention are any mammaUan ceU capable of expressing the genes of interest, or any mammaUan ceUs that can express a cDNA tibrary, cRNA tibrary, genomic DNA library or any protein or polypeptide useful in the method of the invention. MammaUan ceUs also include ceUs from ceU Unes such as those immortalized ceU Unes available from the American Type Culture CoUection (ATCC). Such ceU Unes include, for example, rat pheochromocytoma ceUs (PC 12 ceUs), embryonal carcinoma ceUs (P19 ceUs), Chinese hamster ovary (CHO) ceUs, HeLa ceUs, baby hamster kidney (BHK) ceUs, monkey kidney ceUs (COS), human hepatoceUular carcinoma ceUs (e.g., Hep G2), human embryonic kidney ceUs, mouse sertoli ceUs, canine kidney ceUs, buffalo rat Uver ceUs, human ceUs, human Uver ceUs, mouse mammary tumor ceUs, as weU as others. Also included are hematopoetic stem ceUs, neuronal stem ceUs such as neuronal sphere ceUs, and embryonic stem cells (ES cells). The present invention wtil now be iUustrated by reference to the foUowing examples which set forth particularly advantageous embodiments. However, it should be noted that these embodiments are iUustrative and are not to be construed as restricting the invention in any way. Example 1 A smaU molecule modulator of mammaUan Asx is identified and incorporated into a pharmaceutical composition including a Uposomal-based pharmaceuticaUy acceptable carrier for adniinistration to a cancer patient for controlling the expression or activity of mammaUan Asx in the patient. Adrninistration the composition is achieved by injection into the tumor tissue. The patient is monitored for reduction of mammaUan Asx activity as a diagnostic marker evaluating the effectiveness of the treatment. Example 2 A population of differentiated ceUs are treated with a functional portion of recombinant mammaUan Asx polypeptide and induced to de-differentiate to a less diffeεntiated state. The process is reversed by administering to the population of ceUs an inhibitor of mammaUan Asx activity. The process can be monitored by differential display of mRNA transcripts of the ceUs. Example 3 Northern blots of mRNA isolated from various tissues were probed with a 4.5 kb HindDI fragment of mammaUan Asx cDNA for an analysis of the expression differential of mammaUan Asx in normal and cancerous tissues, using standard techniques for accompUshing the hybridizations. Poly A + RNA was isolated from normal ceUs and cancer ceU Unes. The mRNA was dectrophoreticaUy fractionated and transferred to a nylon filter. The mRNA on the filter was immobilized by UV crosslinking. A labeled probe was prepared from the sequence of SEQ ID NO: 1, labeled with 32 P radionucleotide, and used in a hybridization reaction with the RNA on the filter under stringent conditions. The filter was aUowed to hybridize to the probe, and the unbound probe was washed from the filter. The hybridization was conducted using standard techniques for Northern hybridizations, for example, as described in Sambrook et al (1989), MOLECULAR CLONING: A LABORATORY MANUAL, 2nd ed. (Cold Spring Harbor Press, Cold Spring Harbor, New York). Exposure of the filter to X-ray film showed pronounced bands in the cancer cell Unes, and very tittle activity in the normal cell lines. Beta actin was used as a S97/07806 control to normalize expression levels in the ceU Unes. The normal tissues probed were human adult heart, skeletal muscle, pancreas, prostate, testes, ovary, colon, thymus, brain, placenta, lung, Uver, kidney, peripheral leukocytes, and spleen. The tissue specific expression of hAsx in normal human adult tissue indicated moderate hAsx transcript in human testes, ovary and thymus. Nondetectable or very low quantities of transcript was present in human prostate, colon, brain, placenta, lung, Uver, and kidney, leukocytes, and spleen. Two transcripts, one at about 7.5 kUobases, and one at about 5.5 kUobases were observed in the testes, and only the larger transcript was observed in the ovary and thymus tissues. By contrast, hAsx transcripts were present at a very high level in the foUowing human cancer ceU Unes: promydocytic leukemia HL-60, HeLa ceU S3, chronic myelogenous leukemia K-562, lymphoblastic leukemia MOLT-4, Burkitt's lymphoma Raji, colorectal adenocarcinoma SW480, and melanoma G361. In addition, hAsx transcript was also abundantly expressed in other colorectal adenocarcinoma tissue, and lymphocytic cancer tissues. Expression was very low in the lung cancer tine A549. The hAsx transcripts were about 8.5 kilobases and about 6.5 kUobases in aU these ceU Unes for aU hybridizations. Hybridizations were conducted using stringent conditions and a standard hybridization protocol for accompUshing Northern blot hybridizations. Transcript levels were controUed for by probing with actin probe on the same blots probed with hAsx coding sequence. F.τamp1e 5 A human PI genomic clone was obtained from a PI filter tibrary using an hAsx cDNA as a probe. After DNA preparation , the identity of the clone was confirmed by sequencing a PCR product generated from the Asx PI clone. Sequence matching hAsx exon sequence was interrupted by nonexonic sequence. Consensus sptice donor and acceptor sites were present at the intron-exon boundaries. The hAsx genomic clone was labeled and used as a probe against human metaphase chromosomes. FISH mapping showed that hAsx maps to 20qll.
