Abstract
A human gene has been discovered which is genetically altered in human tumor cells. The genetic alteration is gene amplification and leads to a corresponding increase in gene products. Detecting that the gene, designated hMDM2, has become amplified or detecting increased expression of gene products is diagnostic of tumorigenesis. Human MDM2 protein binds to human p53 and allows the cell to escape from p53-regulated growth.
Claims4
An in vitro method of treating a neoplastic cell, comprising:
- administering to the cell a therapeutically effective amount of antisense oligonucleotides which are complementary to:
- an mRNA comprising SEQ ID NO:2 and encoding human MDM2, and which inhibit expression of human MDM2 protein.
An in vitro method of treating a cell having an amplified human MDM2 gene, elevated expression of human MDM2 mRNA, or elevated expression of human MDM2 protein, comprising:
- administering to the cell a therapeutically effective amount of antisense oligonucleotides which are complementary to an mRNA comprising SEQ ID NO:2 and encoding human MDM2 and which inhibit expression of human MDM2 protein.
An in vitro method of interfering with expression of human MDM2 protein, comprising administering to a neoplastic cell an antisense oligonucleotide which is complementary to:
- an mRNA comprising SEQ ID NO:2 and encoding human MDM2, in an amount effective to interfere with expression of human MDM2 protein.
An in vitro method of interfering with expression of human MDM2 protein, comprising:
- administering to a cell having an amplified human MDM2 gene, elevated expression of human MDM2 mRNA, or elevated expression of human MDM2 protein an antisense oligonucleotide which is complementary to:
- an mRNA comprising SEQ ID NO:2 and encoding human MDM2, in an amount effective to interfere with expression of human MDM2.
