Abstract

Recombinant FGF21 treatment improved hepatic steatosis and insulin resistance through the upregulation of STAMP2 expression.

  • FGF21 administration may reverse liver fat accumulation in nonalcoholic fatty liver disease (NAFLD).
  • STAMP2 expression is associated with the therapeutic effects of FGF21 on NAFLD.
  • Human NAFLD patient samples and mouse models showed signs of hepatic iron overload and decreased ferroportin expression.
  • FGF21 may enhance iron export from the liver by increasing ferroportin levels via STAMP2.
  • STAMP2 could serve as a potential target for therapeutic interventions in FGF21-related NAFLD treatment.
