Abstract/OtherAbstract:
We have previously shown that treatment with (-)-epigallocatechin-3-gallate (EGCG) inhibited vascularity and tumor growth in human colon cancer xenografts in nude mice (Jung et al: Br J Cancer 84, 2001). In this study, we examined whether endothelial cell death by EGCG is mediated by apoptosis and which molecular mechanisms are involved in this process. EGCG was found to suppress cell growth and induce apoptosis largely through mitochondrial depolarization, activation of caspase-3 and cleavage of DNA fragmentation factor-45 in human endothelial ECV 304 cells. The induction of apoptosis by EGCG was confirmed by cleaved and condensed nuclear chromatin and DNA hypoploidy. These results suggest that EGCG may exert at least part of its anticancer effect by inhibiting angiogenesis through inducing endothelial apoptosis.
