(-)-Epigallocatechin gallate (EGCG), the most abundant component in green tea, has a potent anti-apoptotic activity. The purpose of this study was to investigate the protective effects of EGCG and their molecular mechanisms on high glucose-induced apoptosis of human lens epithelial cells (HLEB-3). HLEB-3 cells were exposed to various concentrations of glucose and EGCG. Cell death was assessed by MTT assay and flow cytometry using annexin V and propidium iodide. The expression of the Bcl-2 family, c-fos, c-myc and p53 was measured by real-time PCR. EGCG decreased the Bcl-2/Bax expression stimulated by a high glucose. Moreover, EGCG suppressed the high glucose-induced expression of c-fos, c-myc and p53. These findings suggest that EGCG protects HLEB-3 cells from high glucose-induced apoptosis by regulating the gene expression of the Bcl-2 family, c-fos, c-myc and p53. Thus, EGCG may have a potential protective effect against diabetic cataract formation.
