B1. TNF-α level of cells in each group measured by ELISA.
	OGD+S	OGD+S+NC-siRNA	OGD+S+NRF2-siRNA	F value	DF
TNF-α (ng/L)	48.2±4.5	45.3±4.7	58.8±4.1*	7.684	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<0.05 between OGD+S group and OGD+S+NRF2-siRNA group.
