Chelerythrine Suppresses Proliferation and Metastasis of Human Prostate Cancer Cells via Modulating MMP/TIMP/NF-κB System

The addition of chelerythrine significantly inhibited the proliferation of androgen-independent prostate cancer DU145 and PC-3 cells at the concentration of 5 and 10 μM, but not on androgen-dependent prostate cancer LNCaP cells as well as normal prostate epithelial cell line PrEC cells.

Cytoprotective Autophagy Induction by Withaferin A in Prostate Cancer Cells Involves GABARAPL1

Researchers confirmed autophagy induction by withaferin A (WA) treatment by transmission electron microscopy using three prostate cancer cell lines. Fourteen common genes altered by 8‐ and 16‐hour exposure to WA were identified from human autophagy PCR array and these results were consistent with the RNA‐seq data.

Expression of UDP Glucuronosyltransferases 2B15 and 2B17 Is Associated with Methylation Status in Prostate Cancer Cells

The expression of UGT2B15, UGT2B17, de novo methyltransferases, DNMT3A and DNMT3B was assessed in prostate cancer cells treated with EGF, an EGFR inhibitor PD16893, and the methyltransferase inhibitor, 5-azacytidine, respectively.
