P-231: Androgen Receptor Gene Expression in Azoospermia Men
Background: Androgens are critical steroid hormones in progression of spermatogenesis process and determine the male phenotype that their actions are mediated by the androgen receptor (AR), a member of the nuclear receptor superfamily. In the Androgen receptor, transactivation domain encoded by exon 1, DNA binding domain encoded by exons 2 and 3, hinge region encoded by part of exon 4, and C-te...
متن کاملTranscriptional regulation of androgen receptor gene expression in Sertoli cells and other cell types.
Regulation of androgen receptor (AR) mRNA expression was studied in Sertoli cells and peritubular myoid cells isolated from immature rat testis, and in the lymph node carcinoma cell line derived from a human prostate (LNCaP). Addition of dibutyryl-cyclic AMP (dbcAMP) to Sertoli cell cultures resulted in a rapid transient decrease in AR mRNA expression (5 h), which was followed by a gradual incr...
متن کاملDifferential posttranscriptional regulation of androgen receptor gene expression by androgen in prostate and breast cancer cells.
Androgens, via the androgen receptor (AR), modulate the growth and proliferation of prostate and breast cancer cells. However, the molecular mechanisms underlying the regulation of AR gene expression by androgen in these cells remain to be fully elucidated. To explore differences in AR gene expression between these hormone-responsive tumor cell types, we studied androgen-responsive LNCaP prosta...
متن کاملAndrogen-Responsive MicroRNAs in Mouse Sertoli Cells
Although decades of research have established that androgen is essential for spermatogenesis, androgen's mechanism of action remains elusive. This is in part because only a few androgen-responsive genes have been definitively identified in the testis. Here, we propose that microRNAs--small, non-coding RNAs--are one class of androgen-regulated trans-acting factors in the testis. Specifically, by...
متن کاملP-202: StuI Polymorphism on the Androgen Receptor Gene in Women with Endometriosis
Background: Androgens have an anti-proliferative effect on endometrial cells. Human androgen receptor (AR) gene contains two polymorphic short tandem repeats of GGC and CAG, and a single-nucleotide polymorphism on exon 1 that is recognized by the restriction enzyme, StuI. Prior studies have shown that the lengths of the CAG and GGC repeats are inversely and linearly related to AR activity and a...
