C. The apoptosis rate of cells in each group detected by flow cytometry.
	OGD+S	OGD+S+NC-siRNA	OGD+S+NRF2-siRNA	F value	DF
AI (%)	8.4±2.8	36.1±6.8	18.6±4.3*	48.68	2

One-way ANOVA was used to compare the mean difference among the three groups. Tukey’s multiple comparisons test was used for post hoc test,

^*p<0.001 between OGD+S group and OGD+S+NRF2-siRNA group.
