摘要:
The present invention provides a method of transcriptionally modulating the expression of a gene of interest, the expression of which is associated with a defined physiological or pathological effect within a multicellular organism. The method comprises contacting a cell which is capable of expressing the gene with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell. Molecules useful in the practice of the invention are characterized as follows (a) do not naturally occur in the cell, (b) specifically transcriptionally modulate expression of the gene of interest, and (c) bind to DNA or RNA or bind to a protein through a domain of such protein which is not a ligand binding domain of a receptor which naturally occurs in the cell, the binding of a ligand to which ligand binding domain is normally associated with the defined physiological or pathological effect.

The invention provides a recombinant nucleic acid vector comprising a nucleic acid encoding a polypeptide of 112 amino acids having the amino acid sequence shown in FIG. 29 beginning with alanine at position 1 and ending with serine at position 112. The sequence of FIG. 29 represents a member of the TGF-&bgr; family of tumor growth factors. The invention also provides a method for producing a protein which comprises culturing the host cell under conditions suitable to express the protein in the host cell and recovering the protein so produced.

The invention provides a method for diagnosing in a subject a neoplastic condition which comprises (a) obtaining from the subject a sample of a biological fluid; and (b) detecting the presence in the sample of a mutant p53 polypeptide encoded by an activated p53 oncogene, the presence of the mutant p53 polypeptide in the sample indicating that the subject has the neoplastic condition.

The present invention provides a method of transcriptionally modulating the expression of a gene-of-interest. The method comprises contacting a cell which is capable of expressing the gene with an amount of a molecule effective to transcriptionally modulate expression of the gene and thereby affect the level of the protein encoded by the gene which is expressed by the cell. Molecules useful in the practice of the invention are characterized as follows (a) do not naturally occur in the cell, (b) bind to DNA or RNA or bind to a protein through a domain of such protein which is not a ligand binding domain of a receptor which naturally occurs in the cell. Additionally, this invention provides a method for determining whether a molecule known to be a modulator of protein biosynthesis is capable of transcriptionally modulating expression of a gene-of-interest.

A single-stranded deoxyribonucleic acid molecule having a length of less than about 25 kb comprises at least three distinct nucleotide sequences which are the sites for incorporation into a chromosome of a deoxyribonucleic acid molecule encoding a deleterious gene. Deoxyribonucleic acid probes have been prepared from such molecules and are useful as hybridization probes for detecting chromosomal deoxyribonucleic acid which has a deoxyribonucleic acid molecule encoding a deleterious gene, i.e. oncogene, incorporated therein.A single-stranded deoxyribonucleic acid molecule derived from human chromosome 22 which is about 5.8 kb in length contains sites for incorporation of a deoxyribonucleic acid molecule encoding the oncogene c-abl derived from human chromosome 9. Deoxyribonucleic acid probes have been prepared from this molecule and used to detect the abnormal Philadelphia chromosome and chronic myelocytic leukemia.

This invention is directed to a chromatographically recovered polypeptide having the N-terminal amino acid sequence Ala-Leu-Asp-Thr-Asn-Tyr-Cys-Phe-Arg-Asn-Leu-Glu-Clu-Asn-Cys-Cys-Val. This polypeptide is known as TGI, TGI-1 and TGI-2. It is also referred to as TGF-&bgr;3. The invention is also directed to a compositions which comprises the chromatographically recovered polypeptide. The invention also provides a pharmaceutical compositions to inhibit the growth of epithelial cells or heal a wound or treat a burn consisting of the chromatographically recovered polypeptide. The invention is also directed to methods which comprise administering to a subject an effective amount of the chromatographically recovered so as to thereby inhibit the growth of epithelial cells, or heal the wound or treat the burn.
