  • Patent number: 7153653
    Abstract: The present invention provides a method for detecting a cellular proliferative disorder in a subject. The method includes contacting a nucleic acid-containing specimen from the subject with an agent that provides a determination of the methylation state of at least one gene or associated regulatory region of the gene and identifying aberrant methylation of regions of the gene or regulatory region, wherein aberrant methylation is identified as being different when compared to the same regions of the gene or associated regulatory region in a subject not having said cellular proliferative, thereby detecting a cellular proliferative disorder in the subject.

  • Patent number: 7153657
    Abstract: Methods are provided for detecting a cell proliferative disorder associated with TSLC1 by contacting a proliferating cell of a subject suspected of having the disorder with a reagent that detects TSLC1 and detecting the level of TSLC1 in the proliferating cell. TSLC1 is a single gene whose expression is reduced or absent in A549 and some other NSCLC, hepatocellular carcinoma and pancreatic cancer cell lines. It has further been discovered that TSLC1 expression or suppression is perfectly correlated with promoter methylation state. Restoration of TSLC1 expression to normal or higher levels is sufficient by itself to suppress tumor formation. The invention further provides methods of treating such disorders by contacting cells of a patient suffering from the disorder with a therapeutically effective amount of a reagent that modulates TSLC1 level in the proliferating cells.

  • Publication number: 20050239101
    Abstract: Methods are provided for diagnosing in a subject a condition, such as a carcinoma, sarcoma or leukemia, associated with hypermethylation of genes by isolating the genes from tissue containing as few as 50 to 1000 tumor cells. Using quantitative multiplex methylation specific PCR (QM-MSP), multiple genes can be quantitatively evaluated from samples usually yielding sufficient DNA for analyses of only 1 or 2 genes. DNA sequences isolated from the sample are simultaneously co-amplified in an initial multiplex round of PCR, and the methylation status of individual hypermethylation-prone gene promoter sequences is then determined separately or in multiplex using a real time PCR round that is methylation status-specific. Within genes of the panel, the level of promoter hypermethylation as well as the incidence of promoter hypermethylation can be determined and the level of genes in the panel can be scored cumulatively. The QM-MSP method is adaptable for high throughput automated technology.

  • Publication number: 20050188428
    Abstract: Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. The enhanced rate of mutation can be further augmented using mutagens. Moreover, the hypermutability of mismatch repair deficient cells can be remedied to stabilize cells or mammals with useful mutations.

  • Patent number: 6930175
    Abstract: pp32 is a member of a highly conserved family of differentiation-regulated nuclear proteins that is highly expressed in nearly all human prostatic adenocarcinomas of Gleason Grade?5. This contrasts with the low percentage of prostate tumors that express molecular alterations in proto-oncogens or demonstrate tumor suppressor mutation or loss of heterozygosity. By analysis of specimens of human prostatic adenocarcinoma and paired adjacent normal prostate from three individual patients, the inventors have shown that normal prostate continues to express normal pp32, whereas three of three sets of RT-PCR-amplified transcripts from prostatic adenocarcinomas display multiple cancer-associated coding sequence changes. The cancer-associated sequence changes appear to be functionally significant. Normal pp32 exerts antineoplastic effects through suppression of transformation. In contrast, cancer-associated pp32 variants augment, rather than inhibit, transformation.
