The selective peroxisome proliferator-activated receptor-delta agonist seladelpar reverses nonalcoholic steatohepatitis pathology by abrogating lipotoxicity in diabetic obese mice.

ABSTRACT: Lipotoxicity associated with insulin resistance is central to nonalcoholic steatohepatitis (NASH) pathogenesis. To date, only weight loss fully reverses NASH pathology, but mixed peroxisome proliferator-activated receptor-alpha/delta (PPAR-α/δ) agonists show some efficacy. Seladelpar (MBX-8025), a selective PPAR-δ agonist, improves atherogenic dyslipidemia. We therefore used this agent to test whether selective PPAR-δ activation can reverse hepatic lipotoxicity and NASH in an obese, dyslipidemic, and diabetic mouse model. From weaning, female Alms1 mutant (foz/foz) mice and wild-type littermates were fed an atherogenic diet for 16 weeks; groups (n = 8-12) were then randomized to receive MBX-8025 (10 mg/kg) or vehicle (1% methylcellulose) by gavage for 8 weeks. Despite minimally altering bo
