摘要: Current chemotherapeutic approaches for cancer are in part limited by the inability of drugs to destroy neoplastic cells within poorly vascularized compartments of tumors. We have here systematically assessed anaerobic bacteria for their capacity to grow expansively within avascutar compartments of transplanted tumors. Among 26 different strains tested, one (Clostridium novyi) appeared particularly promising. We created a strain of C. novyi devoid of its lethal toxin (C. novyi-NT) and showed that intravenously injected C. novyi-NT spores germinated within the avascular regions of tumors in mice and destroyed surrounding viable tumor cells. When C. novyi-NT spores were administered together with conventional chemotherapeutic drugs, extensive hemorrhagic necrosis of tumors often developed within 24 hours, resulting in significant and prolonged anti-tumor effects. This strategy, called combination bacteriolytic therapy (COBALT), has the potential to add a valuablle dimension to the treatment of cancer.

摘要: A means for following the growth of experimental neoplasms involves administering recombinant tumor cells containing an expression construct encoding a secretable marker to an experimental animal and measuring secreted marker in the urine of animals bearing tumors formed by such recombinant tumor cells. Urinary marker levels are quantitatively related to tumor loads. Urinary marker can be detected before tumors are grossly visible or clinically apparent. Marker levels decrease following surgical excision or chemotherapeutic treatment, with an estimated half-life of 11 hours. This approach is applicable to the study of many experimental tumor systems.

摘要: Serial analysis of gene expression, SAGE, a method for the rapid quantitative and qualitative analysis of transcripts is provided. Short defined sequence tags corresponding to expressed genes are isolated and analyzed. Sequencing of over 1,000 defined tags in a short period of time (e.g., hours) reveals a gene expression pattern characteristic of the function of a cell or tissue. Moreover, SAGE is useful as a gene discovery tool for the identification and isolation of novel sequence tags corresponding to novel transcripts and genes.

摘要: Specific sequences in the human genome are the sites of strong binding of wild-type p53 protein, but not mutant forms of the protein. These sequences are used diagnostically to detect cells in which the amount of wild-type p53 is diminished. The sequences can also be used to screen for agents which correct for loss of wild-type p53 to DNA in cancer cells.

摘要: The human MSH2 gene, responsible for hereditary non-polyposis colorectal cancer, was identified by virtue of its homology to the MutS class of genes, which are involved in DNA mismatch repair. The sequence of cDNA clones of the human gene are provided, and the sequence of the gene can be used to demonstrate the existence of germ line mutations in hereditary non-polyposis colorectal cancer (HNPCC) kindreds, as well as in replication error.sup.+ (RER.sup.+) tumor cells.

摘要: A new human gene termed MCC is disclosed. Antibody based methods and kits are provided for assessing mutations of the MCC gene in human tissues and body samples. Gross rearrangement and point mutations in MCC are observed in human tumor cells. MCC is expressed in most normal tissues. These results suggest that MCC is a tumor suppressor.

摘要: A two-pronged method for diagnosis of genetic diseases can detect mutations in about 87% of familial adenomatous polyposis (FAP) patients. One part of the diagnostic method employs in vitro protein synthesis from surrogate genes created by amplifying either cDNA or genomic DNA. The second part of the diagnostic method employs an allele-specific expression assay which distinguishes the amount of mRNA expressed in vivo from each of a patient's two alleles. These approaches are readily applicable to the diagnosis of other genetic diseases.

摘要: 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.
