BACKGROUND Prostate cancer is the leading tumor of the male in Western societies. Genetic alterations of the androgen receptor gene are known in the advanced metastatic disease. In this study, the androgen receptor gene was tested in two human prostate cancer cell lines, the androgen-sensitive PC-EW and the androgen-independent PC-OR. MATERIALS AND METHODS Genomic DNA was isolated from two ce...

We have investigated the basis of androgen resistance in seven unrelated individuals with complete testicular feminization or Reifenstein syndrome caused by single amino acid substitutions in the hormone-binding domain of the androgen receptor. Monolayer-binding assays of cultured genital skin fibroblasts demonstrated absent ligand binding, qualitative abnormalities of androgen binding, or a de...

Little is known about the molecular mechanisms of androgen regulation of the FSH gene; however, studies suggest that it consists of a complex feedback loop that involves multiple mechanisms acting at both the level of the hypothalamus and the pituitary. In the present study, we address androgen regulation of the FSH gene in immortalized gonadotrope cells and investigate the roles of activin and...

Androgen insensitivity syndrome (AIS) also called testicular feminizing is a rare X linked disorder of sexual differentiation caused by mutation in the androgen receptor (AR) gene, which located on chromosome (Xq11-q12). In reported cases, individuals with complete (CAIS) presented female appearance and normal breast development, absence uterus ovaries, bilateral undescended testis, elevated te...

The male hormone androgen, working through the androgen receptor (AR), plays a major role in physiological process and disease development. Previous studies of AR mainly focus on its transcriptional activity. Here, we found that androgen-induced TMPRSS2 and ERG gene proximity is mediated by AR control of DNA replication rather than gene transcription. We demonstrate that, in both AR transactiva...
