Arrestin2 modulates androgen receptor activation

TITLE : Inhibitors for Androgen Receptor Activation Surfaces

Androgen receptor activation by polychlorinated biphenyls

The exposure to environmental endocrine disrupting compounds (EDC), as polychlorinated biphenyls (PCBs), widely diffused in the environment may produce epigenetic changes that affect the endocrine system. We found that PCBs activate AR transcriptional activity and that this effect is potentiated by the demethylase Jarid1b, a histone demethylase that catalyzes the removal of trimethylation of ly...

Caveolin-1 Modulates Androgen Receptor Signaling in Advanced Prostate Cancer

CtBP2 modulates the androgen receptor to promote prostate cancer progression.

The androgen receptor (AR) is the key driver of both early and advanced prostate cancer, making a complete understanding of its regulation important. Here, we report the identification of multiple AR-binding sites in the gene encoding the transcription factor CtBP2 (carboxyl terminal-binding protein), genetic variations of which have been associated with prostate cancer susceptibility. Notably,...

Supervillin associates with androgen receptor and modulates its transcriptional activity.

Activation of androgen receptor (AR) via androgen in muscle cells has been closely linked to their growth and differentiation. Here, we report the cloning and characterization of supervillin (SV), a 205-kDa actin-binding protein, as an AR coregulator from the skeletal muscle cDNA library. Mammalian two-hybrid and glutathione S-transferase pull-down assays indicate a domain within SV (amino acid...
