  5. Data, including data from studies using knockout mice, suggest that control of whole-body energy expenditure by Gcgr agonism requires intact Fxr signaling and Fgf21 secretion in liver. (Gcgr = glucagon receptor glucagon; Fxr = farnesoid X receptor; Fgf21 = fibroblast growth factor-21) PMID: 29925501
  6. FGF-21 has anti-inflammatory effects in Type 2 diabetes mellitus PMID: 29414665
  7. These data suggest that Fgf21 acts as one of intrathymic cytokines in the neonatal and juvenile thymus, involving thymocyte development in a beta-Klotho-independent manner. PMID: 28336912
  8. During pregnancy, both systemic and cardiac-produced Fgf21 act on the heart, leading to the normal physiological cardiac changes that are associated with pregnancy. PMID: 28472473
  9. our results demonstrated that FGF21 promotes cell cycle exit and enhances myogenic differentiation of C2C12 cells. This study provided new evidence that FGF21 promotes myogenic differentiation, which could be useful for better understanding the roles of FGF21 in myogenesis. PMID: 29109955
  10. We will clarify the positive and negative signaling mechanisms which control the stress-related expression of FGF21 through the ISR pathway. Moreover, we will examine the role of FGF21 as an interorgan coordinator of survival functions in metabolic and stress disorders. We conclude that FGF21 can be viewed as a cell non-autonomous enhancer of longevity in mammals. PMID: 28844867
  11. under nutrient-limiting conditions that stimulate ATF4 activity, TRIB3 is implicated in the regulation of metabolic adaptation by restraining the transcription of Fgf21. PMID: 29378327

  15. Chronic high-sucrose diet does not lead to obesity in mice. Data suggest that high-sucrose diet leads to up-regulation of Fgf21 expression in liver and brown adipose tissue plus high levels of Fgf21 in plasma which eventually lead to increased energy expenditure and, thus, does not cause obesity in this species. PMID: 28886439
  16. plasma levels of Fgf21 reflect liver fat accumulation and dysregulation of metabolic pathways in the liver. PMID: 27470139

  20. Reduced DNA methylation is associated with enhanced induction of hepatic FGF21 expression after PPARalpha activation, which may partly explain the attenuation of diet-induced obesity in adulthood. PMID: 29434210
  21. These results suggest that FGF21 deficiency slow gastric emptying rate and indirectly influence initial alcohol metabolism in mice exposed to acute alcohol. Our findings provide additional information for understanding the gastrointestinal mechanism of alcoholic liver disease and other alcohol use disorders. PMID: 29448103

  23. Data (including data from studies in knockout mice) suggest that dietary manipulations that induce ketosis also lead to increased HPA axis tone; FGF21 knockout mice exhibit blunted HPA response to ketogenic diet relative to wild-type mice; thus, the hepatokine FGF21 appears to play important role in response to ketogenic diet. (HPA axis = hypothalamic-pituitary-adrenal axis) PMID: 29077838
  24. These results suggest that berberine-induced activation of AMPK may contribute to hepatic FGF21 expression via NUR77. PMID: 29247651
  25. our results demonstrate that Sp1 positively regulates the basal transcription of FGF21 in the liver and adipose tissue and contributes to the obesity-induced FGF21 upregulation in mouse adipose tissue and hepatic FGF21 upregulation in hepatocarcinogenesis. PMID: 28466020
  26. FGF21 deletion aggravates aortic remodeling and cell death probably via exacerbation of aortic inflammation and oxidative stress in type 1 diabetes. PMID: 27391008

  30. FGF21 has a role in promoting remyelination in the central nervous system PMID: 28825598

PMID: 27574977

  33. OPA1 mutant mice are resistant to age- and diet-induced weight gain and insulin resistance, by mechanisms that involve activation of endoplasmic reticulum stress and secretion of fibroblast growth factor 21 (FGF21) from skeletal muscle, resulting in increased metabolic rates and improved whole-body insulin sensitivity.
