The human androgen receptor (AR) is considered as a master regulator in the development and progression of prostate cancer (PCa). As resistance to clinically used anti-AR drugs remains a major challenge for the treatment of advanced PCa, there is a pressing need for new anti-AR therapeutic avenues. In this study, we identified a binding site on the DNA binding domain (DBD) of the receptor …

Previously, we have reported that the pleiotropic cytokine, interleukin (IL)-6, inhibited dihydrotestosterone-mediated expression of prostate-specific antigen in LNCaP cells (Jia et al ., Mol Can Res 2003;1:385–92). The androgen receptor (AR) is expressed in 60%–70% of breast cancers regardless of estrogen receptor status, and has been proposed as a therapeutic target in breast cancers that retain AR. In this study, the authors aimed to investigate a new treatment strategy using a novel AR inhibitor AZD3514 in breast cancer.

In addition to androgenic actions, ar agonists can be classed as selective androgen receptor modulators (sarms) or anabolic androgenic steroids (aas) (​see

Aromatase inhibitors may be used in men to reduce excessive estrogen levels found to bind to testosterone receptors thus reducing active testosterone levels.

A male asked: is there a androgen receptor blocker that only bind to pituitary? Dr. David Masiello answered. 18 years experience The androgen receptor (AR) is expressed in 60%–70% of breast cancers regardless of estrogen receptor status, and has been proposed as a therapeutic target in breast cancers that retain AR. In this study, the authors aimed to investigate a new treatment strategy using a novel AR inhibitor AZD3514 in breast cancer.
