In the liver of NAFLD patients, peroxidases catalase, hemoglobin and paraoxonase 1 are induced, [45–47] but the expression levels of GPX1 and GSR genes are comparable to those of normal livers, [47], suggesting a normal activity in glutathione metabolism in the NAFLD liver. The gene discussed is GPX1; the disease is metabolic dysfunction-associated steatotic liver disease.
