Abstract 2185: Mechanism of antitumor effects of saffron in human prostate cancer cells

Abstract

Abstract Prostate cancer is the most common malignancy in men in the USA and the second leading cause of cancer deaths. Several studies have suggested the antitumor properties of saffron in many types of cancers including prostate. The objective of this study was to carry out in vitro studies of saffron-treated prostate cancer cells to ascertain the effects of saffron on key intermediates in prostate carcinogenesis. Our studies demonstrate significant inhibition of cell proliferation of androgen-sensitive prostate cancer cell lines via apoptotic pathways. We also demonstrate statistically significant down-regulation of DNA methyltransferase; COMT, MGMT, EHMT2, and SIRT1 in saffron-treated prostate cancer cells. In addition, saffron-treated prostate cancer cells displayed statistically significant dysregulation of DNA repair intermediates; WRN, p53, RECQ5, MST1R, and WDR70 in a time-dependent manner. Furthermore, Western blot analysis demonstrated that saffron treatment induced changes in the expression of other key genes; DNMT1, DNMT3b, MBD2, CD44, HDAC3, c-Myc, NF-kB, TNFα, AR, N-RAS and PTEN in prostate cancer cells. Collectively, our findings demonstrate important mechanistic targets of saffron mediating anti-tumor properties in prostate cancer. These findings suggest that the use of saffron supplements alongside standard treatment protocols may yield beneficial effects for individuals with prostate cancer.
