Objective: To investigate the inhibitory effect of Green Tea Polyphenols(GTP) on H2O2-induced lens epithelial cell apoptosis and relevant mechanism.Methods: Separated and cultivated lens epithelial cell
disposed that with GTP
then detected the inhibitory effect of GTP by electron transmission microscopy
flow cytometry and DNA fragmentation assay.The bcl-2
Bax and caspase-3 protein expression were measured with Western-blot in various groups.Results: The apoptosis cells and G1 phase cells increased in the group treated with sodium chloride solution
and the DNA "ladder" was found.In the group treated with GTP
the apoptosis cells and G1 phase cells decreased
and no DNA "ladder".The apoptosis protein bcl-2 increased
however
the Bax and caspase-3 protein decreased.Conclusion: The GTP can protect lens epithelial cells from the oxidative injury and restrain the apoptosis rate of lens epithelial cells and the mechanism was nearly correlated with bcl-2
Bax and caspase-3 protein.
