Role of fibroblast growth factor 21 in the early stage of NASH induced by methionine- and choline-deficient diet.

ABSTRACT: Fibroblast growth factor 21 (FGF21) is a modulator of energy homeostasis and is increased in human nonalcoholic liver disease (NAFLD) and after feeding of methionine- and choline-deficient diet (MCD), a conventional inducer of murine nonalcoholic steatohepatitis (NASH). However, the significance of FGF21 induction in the occurrence of MCD-induced NASH remains undetermined. C57BL/6J Fgf21-null and wild-type mice were treated with MCD for 1 week. Hepatic Fgf21 mRNA was increased early after commencing MCD treatment independent of peroxisome proliferator-activated receptor (PPAR) α and farnesoid X receptor. While no significant differences in white adipose lipolysis were seen in both genotypes, hepatic triglyceride (TG) contents were increased in Fgf21-null mice, likely due to the up-regulati
