DNMT1 regulates IL-6- and TGF-β1-induced epithelial mesenchymal transition in prostate epithelial cells.

ABSTRACT: Multiple factors have been considered to play a role in the development of benign prostatic hyperplasia (BPH), including chronic inflammation, hormones, and epithelial-mesenchymal transition (EMT). Inflammation is regarded as one of the potential inducers of EMT. However, the mechanisms, modulating pro-inflammatory factors (IL-6 and TGF-β1) induce EMT features, have not yet been studied in BPH. In this study, we investigated whether DNA methyltransferases1 (DNMT1) could regulate IL-6 and TGF-β1 induce EMT. The expression of EMT features was analyzed in normal prostate epithelial cells (PrECs) and BPH1 cells. Real-time RT-PCR and western blotting were used to examine the expression of EMT features in IL-6- and TGF-β1-treated PrECs. Next, bisulfite sequencing PCR (BSP) methods were used to e
