Abstract: OBJECTIVE: To investigate the effects of epigallocatechin gallate (EGCG) on cisplatin (DDP)-induced cytotoxicity in human embryo kidney (HEK) 293 cells and A549 cells. METHODS: HEK293 cells and A549 cells were cultured in vitro,and effects of DDP and EGCG on HEK293 cells and A549 cells were observed by MTT. The cells were divided into control group,DDP group and DDP+EGCG group. Then,the rates of HEK293 and A549 cell death were investigated by MTT. RESULTS: The IC50 of EGCG on HEK293 cells was 61.6 mg/L. At lower than 40 mg/L,EGCG had no significantly effects on DDP-induced HEK239 cell death. At higher than 40 mg/L,EGCG significantly enhanced DDP-induced HEK239 cell death. The IC50 of EGCG on A549 cells was 33.6 mg/L. At higher than 40 mg/L,EGCG significantly enhanced DDP-induced A549 cell death. CONCLUSION: EGCG had no significant protective effects on DDP-induced HEK239 cell death,but EGCG induced more cytotoxicity on cancer cells than on normal cells. When co-treated with DDP,A549 cell sustained more damage than HEK239 cells.
