摘要
Objective: We explored the mechanism of apoptosis in human esophageal cancer Ecal09 cells by resveratrol. Methods: The suppressive ratio of resveratrol on Ecal09 cells proliferation was evaluated by MTT colorimetric assay and morphology was observed by transmission electron microscope. The expression of survivin and bax was analyzed by RT-PCR and Flow Cytometry (FCM). Results: Resveratrol inhibited the growth of Ecal09 calls in a dose-and time-dependent man- ner, and the suppressive ratio arrived at 76.42%. Morphological apoptosis could be observed after treated with resveratrol.The bulk of some drug-treated cells turned small and the nuclear chromatin became condensed and rnarginated. The results determined by RT-PCR and FCM showed that resveratrol could down-regulate surviving, while up-regulate bax. Conclusion: Resveratrol could induce the apoptosis of human esophageal cancer Ecal09 cells, and its possible molecular mechanisms might be related to modulation the expression of survivin and bax.
