In atherogenic diet-fed Wt mice, administration of Seladelpar sodium salt reduces body weight by ~18% (P<0.05). In contrast, Seladelpar sodium salt produces minimal effect on body weight in atherogenic diet-fed foz/foz mice. Seladelpar sodium salt lowers serum alanine aminotransferase (ALT) levels in foz/foz mice (P<0.05) and similarly (but not significantly) in Wt mice. Seladelpar sodium salt normalizes serum cholesterol and decreases triglycerides in both genotypes (P<0.05). Seladelpar sodium salt abolishes hepatocyte ballooning (P<0.05) and decreases the nonalcoholic fatty liver disease (NAFLD) activity score by ~50%. Seladelpar sodium salt also significantly reduces sirius red-positive areas in foz/foz mice (P<0.05).
