Genetic mutation or loss of activin/transforming growth factor-beta (TGFbeta) receptor function has been shown in human lymphoid, breast, and colorectal tumors as well as Hep2B and Mv1Lu cell lines. Although activin stimulates FSHbeta biosynthesis and secretion, a large percentage of human gonadotroph tumors have previously been demonstrated to be nonresponsive to characterized activin effects....

Breast cancer in families with germ line mutations in the TP53 gene has been described in the medical literature. Mutation screening for susceptibility genes should allow effective prophylactic and preventive measures. Using single-strand conformational polymorphism, we screened for mutations in exons 5, 6, 7 and 8 of gene TP53 in the peripheral blood of 8 young non-affected members (17 to 36 y...

Single-stranded conformational polymorphism (SSCP) analysis is useful for mutation detection and polymorphism identification. To realize high-throughput SSCP analysis using a high-intensity electric field, the gel temperature must be well-controlled. We have developed an electrophoretic system having a pair of glass plates with an efficient temperature-controlling apparatus on each side of the ...
