CA exerts an antiapoptotic effect through the miR-34a/SIRT1/p66shc pathway in L02 cells. L02 cells were treated with or without PA and then transfected with antago-miR-34a for 24 h or incubated with 10 μM CA for 12 h. (a) TUNEL assay ( × 200), (b) Caspase-3 and caspase-9 activity, (c) miR-34a expression and (d) SIRT1 and p66shc protein expression. The data are presented as the mean±S.D. (n=3). *P<0.05 versus the ND group, **P<0.01 versus the control group, ##P<0.01 versus the PA group, &&P<0.01 versus the PA+antago-miR control group
