A procedure was developed for measurement of androgen receptors in cytoplasmic extracts of prostates from intact dogs. The protocol utilized exchange saturation analysis at 15 degrees C employing the synthetic androgen R1881 (17beta-hydroxy-17alpha-methylestra-4,9,11-trien-3-one) as the ligand probe and quantitatively detected total cytoplasmic androgen receptor (R(c), androgen-free receptor, a...
BACKGROUND AND AIMS Although Breast carcinoma had many targeted biomarkers for its treatment, however, it is a heterogeneous disease with different outcomes and need new markers especially for the triple negative group when estrogen receptor, progesterone receptors and Her2/neu are negative. Androgen receptor is a new target with unclear role. The aim of this study was to examine the prevalence...
This review presents the androgen receptor gene and its clinical importance in gynecology, oncology and infertility. A computerized literature search through Medline and PubMED was performed, applying the word " androgen receptor " cited between the years 1990 and 2009. The androgen receptor mediates androgen action, determining male sexual phenotypes and spermatogenesis. Constitutional mutatio...
Background: Neuroblastoma is the most common extracranial tumors in children. At present about the true etiology of neuroblastoma is unclear and many studies have tried to find effective treatments for these primary malignant tumors. Although it has been illustrated that androgen receptor (AR) was expressed in neuroblastoma cells in some former reports, the biological role of androgen receptor ...
Animal studies showed that male gastric tissues respond more rapidly to Helicobacter pylori (H.pylori) infection but the possible mechanisms remained unclear. There is no data about gender specific activity of Androgen receptor (AR) as an independent unfavorable prognostic factor in gastric cancer and its interactions with H.pylori and angiogenesis in both genders. To compare the pathogenesis o...
The human androgen receptor plays a major role in the development and progression of prostate cancer and represents a well-established drug target. All clinically approved androgen receptor antagonists possess similar chemical structures and exhibit the same mode of action on the androgen receptor. Although initially effective, resistance to these androgen receptor antagonists usually develops ...

Androgen receptor signaling plays a critical role in prostate cancer pathogenesis. Yet, the regulation of androgen receptor signaling remains elusive. Even with stringent androgen deprivation therapy, androgen receptor signaling persists. Here, our data suggest that there is a complex interaction between the expression of the tumor suppressor miRNA, miR-31, and androgen receptor signaling. We e...
The androgen receptor is a member of the family of nuclear receptors. In its activated form as an androgen receptor ligand complex (the ligand can either be testosterone or 5a-dihydrotestosterone), the androgen receptor is able to regulate a specific expression of target genes. The androgen receptor is expressed at high levels in male reproductive tissues. Mutations in the androgen receptor gen...
UNLABELLED Metastatic prostate cancer is initially treated with androgen ablation therapy, which causes regression of androgen-dependent tumors. However, these tumors eventually relapse resulting in recurrent castration-resistant prostate cancer (CRPC). Currently, there is no effective therapy for CRPC and the molecular mechanisms that lead to the development of CRPC are not well understood. He...
