摘要:
The present invention relates generally to the field of human genetics. Specifically, the present invention relates to methods and materials used to isolate and detect a human breast and ovarian cancer predisposing gene (BRCA1), some mutant alleles of which cause susceptibility to cancer, in particular breast and ovarian cancer. More specifically, the invention relates to germline mutations in the BRCA1 gene and their use in the diagnosis of predisposition to breast and ovarian cancer. The present invention further relates to somatic mutations in the BRCA1 gene in human breast and ovarian cancer and their use in the diagnosis and prognosis of human breast and ovarian cancer. Additionally, the invention relates to somatic mutations in the BRCA1 gene in other human cancers and their use in the diagnosis and prognosis of human cancers. The invention also relates to the therapy of human cancers which have a mutation in the BRCA1 gene, including gene therapy, protein replacement therapy and protein mimetics. The invention further relates to the screening of drugs for cancer therapy. Finally, the invention relates to the screening of the BRCA1 gene for mutations, which are useful for diagnosing the predisposition to breast and ovarian cancer.
摘要:
A specific region of chromosome 10 (10q23.3) has been implicated by series of studies to contain a tumor suppressor gene involved in gliomas, as well as a number of other human cancers. One gene within this region was identified, and the corresponding coding region of the gene represents a novel 47 kD protein. A domain of this product has an exact match to the conserved catalytic domain of protein tyrosine phosphatases, indicating a possible functional role in phosphorylation events. Sequence analyses demonstrated the a number of exons of the gene were deleted in tumor cell lines used to define the 10q23.3 region, leading to the classification of this gene as a tumor suppressor. Further analyses have demonstrated the presence of a number of mutations in the gene in both glioma and prostate carcinoma cells. Methods for diagnosing and treating cancers related to this tumor suppressor, designated as TS10q23.3, also are disclosed.

摘要:
The present invention is directed to cloning the ends of genes. Traditionally it has been very difficult to recover the 5' end of a gene. The present invention greatly eases this problem. The invention is a variation on RACE and uses a combination of techniques. Specific genes are purified by using three enrichment steps--1) a polymerase chain reaction, 2) a hybrid capture step, and 3) a second polymerase chain reaction. The inclusion of the hybrid capture step results in a greater enrichment than occurs with RACE. The ends of the gene are retained by use of a novel technique of attaching adaptors at the ends of the nucleic. The 5' end of the gene is conserved by preparing a first strand of cDNA and ligating to this an adaptor which is partially double stranded wherein the overhang or single stranded region of the adaptor is degenerate which allows for a fraction of the adaptor population to hybridize with the first strand of cDNA at the 3' end of the cDNA. This hybridization holds the adaptor in conjunction with the cDNA during the ligation step thereby resulting in a highly efficient ligation. The unique portion of the adaptor is used to design an oligomer to prime the second strand synthesis. None of the 5' sequence is lost in this method thereby allowing for a greater possibility of recovering the extreme 5' end of the gene.
