Induction of apoptosis in prostate cancer cell lines by the green tea component, (-)-epigallocatechin-3-gallate

Cancer Lett. 1998 Aug 14;130(1-2):1-7. doi: 10.1016/s0304-3835(98)00084-6.


Green tea components exert many biological effects, including antitumor and cancer preventive activities. In the search for anticancer agents for prostate cancer the inhibitory effects of green tea components were tested on the prostate cancer cell lines LNCaP, PC-3 and DU145. (-)-Epigallocatechin-3-gallate (EGCG) proved to be the most potent catechin at inhibiting cell growth. The inhibition induced by EGCG was found to occur via apoptotic cell death as shown by changes in nuclear morphology and DNA fragmentation. Thus, we report the first evidence that EGCG is the active component in green tea and induces apoptosis in human prostate cancer cells.
