Increased liver weight, liver weight/body weight ratios, and serum aminotransferase (ALT), aspartate aminotransferase (AST) levels, total cholesterol (TC) and triglyceride (TG) levels indicated that HFD/STZ mice had hepatic steatosis and damage, as observed in H&E‐stained liver sections and a higher NAFLD activity score (NAS) (Figure S1H–N, Supporting Information). Here, GPT is linked to metabolic dysfunction-associated steatotic liver disease.
