MIR877-3P inhibited VEC autophagy and apoptosis. After transfection with MIR877-3P mimics or inhibitor overnight, VECs were treated with HG for 48 h. (a,b) Western blot analysis of LC3B-II level. (c) TUNEL staining analysis of cell apoptosis. Scale bar: 100 μm. (d,e) Cell apoptosis was detected by Hoechst 33258 staining. Scale bar: 30 μm. (*, p < 0.05; **, p < 0.01; n = 3.).
