Shen et al. (Shen et al., 2022a) established a MI model by ligating the left anterior descending coronary artery in rats and found that salvianolic acid B activated the NRF2 signalling pathway, increased SLC7A11, GPX4, FPN, and FTH1 expression, inhibited ferroptosis, and alleviated MI. The gene discussed is GPX4; the disease is myocardial infarction.
