Differential regulation by melatonin of cell growth and androgen receptor binding to the androgen response element in prostate cancer cells.

Abstract excerpt

OBJECTIVES: The pineal hormone melatonin inhibits the growth of benign human prostate epithelial cells and the androgen-dependent prostate cancer LNCaP cells. In the androgen-nonresponsive prostate carcinoma PC3 cells melatonin inhibits cell growth only at high but not low cell density. We have recently found that melatonin causes nuclear exclusion of the AR and attenuates it transcriptional activity in LNCaP...
