Fig. 4From: Protective effects of aucubin on osteoarthritic chondrocyte model induced by hydrogen peroxide and mechanical stimulusEffect of aucubin on caspase-3 activity. Chondrocytes pretreated with 100 μM of aucubin or Z-VAD-FMK as caspase inhibitor for 24 h were then stimulated with 1 mM H2O2 for 30 min. Chondrocytes without aucubin nor H2O2 treatment were set as the control group. Results shown represent mean ± SD obtained from five repeated measurements. *p < 0.05 compared with the control group. # p < 0.05 compared with the H2O2 groupBack to article page
