BACKGROUND Association studies have examined the significance of several candidate genes based on biological pathways relevant to prostate carcinogenesis, including both the androgen and insulin-like growth factor pathways. Clinical and epidemiologic evidence suggest that androgens, specifically testosterone and dihydrotestosterone (DHT) are important not only in normal prostate growth but in t...
Inhibin, a member of the TGF-beta superfamily, has been proposed to act as an inhibitor of activin and bone morphogenetic protein (BMP) by sequestering their type II receptors in nonsignaling complexes with betaglycan. This mechanism of inhibin action was tested in a mouse adrenocortical (AC) cell line by examining the effects of inhibins A and B on cytochrome P450 17alpha-hydroxylase 17,20-lya...
We previously reported that our novel compound 3beta-hydroxy-17-(1H-benzimidazole-1-yl)androsta-5,16-diene (VN/124-1) is a potent 17alpha-hydroxylase/17,20-lyase (CYP17) inhibitor/antiandrogen and strongly inhibits the formation and proliferation of human prostate cancer LAPC4 tumor xenografts in severe combined immunodeficient mice. In this study, we report that VN/124-1 and other novel CYP17 ...
BACKGROUND The cytochrome P450c17alpha enzyme functions in the steroid biosynthesis pathway, and altered endogenous steroid hormone levels have been reported to be associated with a T to C polymorphism in the 5' promoter region of the CYP17 gene. Because steroid hormone exposure is known to influence breast cancer risk, we conducted a population-based, case-control-family study to assess the re...
