Genes encoding hormone receptors are among candidate genes modulating the risk of ovarian cancer. We aimed to assess a frequency of PGRG+331A, FSHRAla307Thr, and FSHRSer680Asn polymorphic variants, and the length of (CAG)n and (GGN)n repeat tracts in the androgen receptor gene (AR) with respect to ovarian cancer risk and outcome. We genotyped 215 ovarian cancer patients and 352 unaffected contr...

OBJECTIVE Present study was designed for carrying out the mutational analysis of the entire Androgen receptor (AR) gene including two microsatellite (CAG)n, (GGN)n, promoter region in cases of premature ovarian failure (POF) and primary amenorrhea (PA). DESIGN Previous reports of AR knockout mice model showed POF phenotype, this draws an attention on the role of AR gene in the aetiology of PO...

The association between androgen receptor gene polymorphisms and benign prostatic hyperplasia was investigated among 510 men randomly selected from Olmsted County, Minnesota. From 1990 through 2000, lower urinary tract symptom severity was assessed by the American Urological Association Symptom Index (AUASI), and peak urinary flow rate, prostate volume, and serum prostate-specific antigen level...

The aim of the present study was to evaluate the distribution of polymorphisms for the androgen receptor (AR) (CAG, StuI, GGN), SRD5A2 (Ala49Thr, Val89Leu) and CYP17 (MspA1) genes that are considered to be relevant for risk of prostate cancer. We studied 200 individuals from two cities in the State of São Paulo, by PCR, PCR-RFLP and ASOH techniques. The allelic frequencies of the autosomal mark...

BACKGROUND We investigated the androgen receptor gene GGN polymorphism and its relation to male infertility and receptor function. METHODS Ninety-nine infertile patients with sperm counts < or = 5 x 10(6)/ml were screened for karyotypic abnormalities and Y-chromosome microdeletions. The GGN and CAG repeats were sequenced in those without genetic abnormalities and in 223 controls. RESULTS Fi...

Although the association between CAG and GGN repeats in the androgen receptor gene and prostate cancer risk has been widely studied, it remains controversial from previous meta-analyses and narrative reviews. Therefore, we performed this meta-analysis to provide more precise estimates with sufficient power. A total of 51 publications with 61 studies for CAG repeats and 14 publications with 16 s...

The functional role of the GGN repeat in the human androgen receptor gene is unknown, although mutations in this region have been found in patients with inter-sex conditions. We have investigated the prevalence of GGN mutations in the androgen receptor in the Swedish population and their relation to male reproductive function. A physical examination and semen analysis was carried out in 223 men...

Ovarian cancer is the main cause of death among women with gynecological malignancies. Androgen and its receptors play an important role in ovarian cancer pathogenesis. Here, We aim to evaluate the relationship between AR CAG and GGN repeat length polymorphisms and Epithelial Ovarian Cancer (EOC) risk in a two-stage, case-control study among Chinese women. The repeat length was analyzed as a ca...

آندروژن ها نقشی اساسی در تمایز ثانویه جنسی، از جمله اسپرماتوژنز بازی می کنند که این اعمال به واسطه گیرنده آندروژن انجام می گیرد. ژن کد کننده گیرنده آندروژن انسانی (ar) دارای دو تکرار پلی مورفیک cag و ggn در اگزون اول خود می باشد. تا کنون نقش تکرار cag به خوبی در چندین اختلال بالینی از جمله ناباروری، بررسی شده است اما عملکرد دقیق ggn هنوز نامشخص است و اطلاعات ناچیزی در مورد آن وجود دارد. در این ...
