Indirect CAR activation pathways, particularly involving PFOA, are discussed in the context of PPARα-independent mechanisms leading to hepatotoxicity, including hepatocellular hypertrophy and necrosis, and their implications in nonalcoholic steatohepatitis (NASH) and nonalcoholic fatty liver disease (NAFLD). The gene discussed is PPARA; the disease is metabolic dysfunction-associated steatotic liver disease.
