Caveolin-1 Interacts with Androgen Receptor

Caveolin-1 interacts with androgen receptor. A positive modulator of androgen receptor mediated transactivation.

Androgen receptor (AR) belongs to the steroid hormone nuclear receptor superfamily. It functions as an androgen-dependent transcriptional factor that regulates genes for cell proliferation and differentiation. Caveolin is a principal component of caveolae membranes serving as a scaffold protein of many signal transduction pathways. Recent results correlate caveolin-1 expression with androgen se...

Peroxiredoxin 1 interacts with androgen receptor and enhances its transactivation.

Although hypoxia is accepted as an important microenvironmental factor influencing tumor progression and treatment response, it is usually regarded as a static global phenomenon. Consequently, less attention is given to the impact of dynamic changes in tumor oxygenation in regulating the behavior of cancer cells. Androgen receptor (AR) signaling plays a critical role in prostate cancer. We prev...

Caveolin-1 Modulates Androgen Receptor Signaling in Advanced Prostate Cancer

Androgen receptor interacts with a novel MYST protein, HBO1.

The androgen receptor (AR), a member of the nuclear receptor superfamily, plays a central role in male sexual differentiation and prostate cell proliferation. Results of treating prostate cancer by androgen ablation indicate that signals mediated through AR are critical for the growth of these tumors. Like other nuclear receptors, AR exerts its transcriptional function by binding to cis-element...

Androgen Receptor Localizes to Plasma Membrane by Binding to Caveolin-1 in Mouse Sertoli Cells

The nonclassical androgen signaling pathway translates signals into alterations in cellular function within minutes, and this action is proposed to be mediated by an androgen receptor (AR) localized to the plasma membrane. This study was designed to determine the mechanism underlying the membrane association of androgen receptor in TM4 cells, a mouse Sertoli cell line. Western blot analysis ind...
