The activation of STAT3 in OGD/R-induced MLE12 ferroptosis was regulated by Nrf2. (a) Cells were transfected with Nrf2 interfering lentiviruses and then subjected to OGD/R. The level of GPX4, STAT3, and pSTAT3 expression was measured by western blot. ∗P < .05, ∗∗P < .01, ∗∗∗P < .001, #P < .05, ##P < .01, and ###P < .001 between the groups. ∗Compared with the control group; #shNC group compared with the shNrf2 group. (b) Cells overexpressing Nrf2 and then subjected to OGD/R. The level of GPX4, STAT3, and pSTAT3 was measured by western blot. ∗P < .05, ∗∗P < .01, ∗∗∗P < .001, #P < .05, ##P < .01, and ###P < .001 between the groups. ∗Compared with the control group; #shNC group compared with the shNrf2 group.
