B3. IL-6 level of cells in each group measured by ELISA.
	OGD+S	OGD+S+NC-siRNA	OGD+S+NRF2-siRNA	F value	DF
IL-6 (ng/L)	138.2±19.7	123.8±17.7	195.4±24*	10.11	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.
