摘要：Epigallocatechin-3-O-gallate (EGCG), the major polyphenol of green tea and a functional food ingredient/nutraceutical with health-promoting properties. However, its anti-cancer activities on various cancer cells are still little information. Here, we show that anti-cancer activities of the EGCG were evaluated using apoptosis assays analyzed by flow cytometry. The inhibitory activities of proliferation in MPC-11, Caco-2, and MCF-7 cells, values were 66.2, 60.3, and 74.8% at 10 μM, respectively. In addition, in an flow cytometry assay on the MPC-11, Caco-2, and MCF-7 cells, the EGCG showed a cell apoptosis effect on cancer/tomor in vitro model. Our results indicate that EGCG has anti-cancer activities against human lung cancer cells through inducing cell cycle arrest, DNA damage and activating mitochondrial signal pathway. These results indicate that EGCG effectively inhibits in vitro tumor growth by inducing apoptosis of cancer cells.
