We also measured the mRNA expression of ferroptosis-related genes in the liver with and without steatosis after partial hepatectomy and found that hepatic expression of Gpx4 was not different between these two conditions and that that of Slc7a11, another anti-ferroptotic gene, showed an insignificant increasing tendency in severe hepatic steatosis (Fig. 1g). The gene discussed is GPX4; the disease is Hepatic steatosis.
