Nrf2 and STAT3 Alleviates Ferroptosis-Mediated IIR-ALI by Regulating SLC7A11

Figure 7

Interference with STAT3 expression may exacerbate OGD/R-induced ferroptosis. Cells transfected with the STAT3 interference lentivirus were subjected to OGD/R. (a) The relative level of STAT3, pSTAT3, and SLC7A11 protein expression after interfering with STAT3. The pSTAT3 intensity was normalized to the corresponding level of STAT3. The STAT3 and SLC7A11 intensity were normalized to the corresponding level of β-actin, and the changes are shown in the histograms. and between the groups. shSTAT3 group compared with that of the shNC group. (b) The cell proliferation activity was measured with a CCK8 assay after OGD/R and treated with Fe or Fer-1. , , and between the groups. shSTAT3 group compared with that of the shNC group.
