Abstract

Acetaminophen (APAP) overdose is a leading cause of drug-induced hepatotoxicity and acute liver failure worldwide, but its pathophysiology remains incompletely understood. Fibroblast growth factor 21 (FGF21) is a hepatocyte-secreted hormone with pleiotropic effects on glucose and lipid metabolism. This study aimed to investigate the pathophysiological role of FGF21 in APAP-induced hepatotoxicity in mice. In response to APAP overdose, both hepatic expression and circulating levels of FGF21 in mice were dramatically increased as early as 3 hours, prior to elevations of the liver injury markers alanine aminotransferase (ALT) and aspartate aminotransferase (AST). APAP overdose-induced liver damage and mortality in FGF21 knockout (KO) mice were markedly aggravated, which was accompanied by increased oxidative stress and impaired antioxidant capacities as compared to wild-type (WT) littermates. By contrast, replenishment of recombinant FGF21 largely reversed APAP-induced hepatic oxidative stress and liver injury in FGF21 KO mice. Mechanistically, FGF21 induced hepatic expression of peroxisome proliferator-activated receptor coactivator protein-1α (PGC-1α), thereby increasing the nuclear abundance of nuclear factor erythroid 2-related factor 2 (Nrf2) and subsequent up-regulation of several antioxidant genes. The beneficial effects of recombinant FGF21 on up-regulation of Nrf2 and antioxidant genes and alleviation of APAP-induced oxidative stress and liver injury were largely abolished by adenovirus-mediated knockdown of hepatic PGC-1α expression, whereas overexpression of PGC-1α was sufficient to counteract the increased susceptibility of FGF21 KO mice to APAP-induced hepatotoxicity. Conclusion: The marked elevation of FGF21 by APAP overdose may represent a compensatory mechanism to protect against the drug-induced hepatotoxicity, by enhancing PGC-1α/Nrf2-mediated antioxidant capacity in the liver.

  • FGF21's triglyceride-lowering effects are mediated by altered adipose and liver metabolism: accelerated lipoprotein catabolism, suppression of postprandial lipolysis, decreased hepatic ER and oxidative stress, and increased beta-oxidation of lipids in the liver.

    “Pharmacological administration of FGF21 or FGF21 analogues exerts lipid-lowering effects through accelerated lipoprotein catabolism108, suppression of postprandial lipolysis in adipose tissues88, decreased hepatic endoplasmic reticulum and oxidative stress109,110, and increased beta-oxidation of lipids in the liver62”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
