background: hypospadias is one of the most common congenital abnormalities in the male which is characterized by altered development of urethra, foreskin and ventral surface of the penis. androgen receptor gene plays a critical role in the development of the male genital system by mediating the androgens effects. objective: in present study, we looked for new variations in androgen receptor pro...

the androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resemble males. the primary abnormality is a defective androgen receptor protein due to a mutation of the androgen receptor gene. this prevents normal androgen action and thus leads to impaired virilization. a point m...

mutations of the androgen receptor (ar) gene give rise to a wide array of phenotypic abnormalities. various mutations of the ar gene and expanded polyglutamine repeats (cag) at exon 1 of the gene have been reported in patients with infertility and neurodegenerative diseases. however, the role of the ar gene trinucleotides repeats has not been systemically studied in those with hypospadias or ge...

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...

Our previous study demonstrated that an extract of Cordyceps militaris (CM) derived from Samia Cynthia ricini inhibits testosterone-induced prostate hypertrophy in animal model. However, the bioactive components CM modulate function cells have not been identified and characterized. To do this, present explored effective component(s) influences viability androgen-responsive LNCaP cancer androgen...

background and objective: determination of hormone receptor status in the management of breast cancer is well-established. the aim of this study was to evaluate the frequency of androgen receptor (ar) expression in invasive ductal carcinoma of breast. materials and methods: for this purpose, 55 cases of invasive ductal breast carcinoma were examined using a monoclonal antibody against ar on for...

background: androgens play critical role in secondary sexual and male gonads differentiations such as spermatogenesis, via androgen receptor. the human androgen receptor (ar) encoding gene contains two regions with three nucleotide polymorphic repeats (cag and ggn) in the first exon. unlike the cag repeats, the ggn has been less studied because of technical difficulties, so the functional role ...

Prostate cancer is the most commonly diagnosed and second leading cause of mortality in men Western World. In initial stages, prostate dependent on androgens for growth which basis androgen ablation therapy. The effects are mediated by Androgen Receptor (AR). Therefore, studies focus identification AR-regulated genes that also highly expressed prostate. STAMP family STAMP1/STEAP2 STAMP2/STEAP4 ...

Background: Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder affecting 4-12% of reproductive women worldwide; characterized by chronic anovulation, clinical and/or biochemical hyperandrogenism, and polycystic ovaries on ultrasound scan. Ovarian androgen overproduction is the key pathophysiologic feature of PCOS. A number of genes encoding major enzymes of the androgen meta...
