piR‐823 inhibits cell apoptosis. (a, b) Cell apoptosis of Ant‐823 or NC‐transfected HCT116 and DLD‐1 cells was determined by Annexin V/PI staining (a) and TUNEL technology (b). Scale bar, 50 μm. (c) Activated apoptosis‐related proteins caspase‐8, caspase‐9 and caspase‐3 were assessed by western blot analysis in HCT116 and DLD‐1 cells. All values are the mean ± SD from three independent experiments, **P < 0.01, ***P < 0.001 vs NC.
