The androgen receptor (AR) is a nuclear receptor that functions as a transcription factor and regulates the development and growth of the prostate. The AR, when bound by a ligand, complexes with DNA at androgen response elements in the promoter region of target genes. Transcription factor activity is modulated by bound coactivator and corepressor proteins like ZBTB7A that recruits NCOR1 and NCOR2 to the androgen response elements/ARE on target genes, negatively regulating androgen receptor signaling and androgen-induced cell proliferation (PubMed:20812024). Welcome to the Androgen Receptor Gene Mutations Database World Wide Web Server. This server is for all who are interested in mutations of the Androgen Receptor Gene.

Gottlieb B, Beitel LK, Nadarajah A, Palioura M, Trifiro M. 2012. The human androgen receptor (AR) is a protein encoded by a gene located on the proximal long arm of the X chromosome (locus Xq11-Xq12). The protein coding region consists of approximately 2,757 nucleotides (919 codons) spanning eight exons, designated 1-8 or A-H. Introns vary in size between 0.7 and 26 kb. 2020-02-02 · Androgens such as testosterone and DHT binds to the androgen receptor to exert their actions. If you want to build muscle, grow a bread, have a deep voice, etc., your androgens got to bind to the androgen receptors in order to do that. 2014-06-09 · The androgen receptor (AR) (NR3C4, nuclear receptor subfamily 3, group C, gene 4) belongs to the steroid hormone group of nuclear receptors with the estrogen receptor (ER), glucocorticoid receptor The gene encoding androgen receptor (AR), alternatively known as the dihydrotestosterone receptor, is located on the X chromosome. It is mutant in the androgen insensitivity syndrome (AIS; 300068 ), formerly known as the testicular feminization syndrome (TFM), and in Kennedy spinal and bulbar muscular atrophy (SBMA; 313200 ).

The expression level of the androgen receptor ( AR ) gene in androgen-dependent and -independent prostate cancer was determined by using real-time quantitative reverse transcription-PCR assay. Eight benign prostate hyperplasias, 33 untreated and 13 hormone-refractory locally recurrent carcinomas, as well as 10 prostate cancer xenografts, were analyzed. All hormone-refractory tumors expressed Androgen has anabolic effects on cardiac myocytes and has been shown to enhance left ventricular enlargement and function. However, the physiological and patho-physiological roles of androgen in cardiac growth and cardiac stress-induced remodeling remains unclear. We aimed to clarify whether the androgen-nuclear androgen receptor (AR) system contributes to the cardiac growth and angiotensin II Androgen receptors allow cells to respond to androgens, which are hormones (such as testosterone) that direct male sexual development.
