Non-alcoholic fatty liver disease (NAFLD) is a prevalent obesity-related disease
that affects large populations throughout the world due to excessive calorie
intake and an increasingly sedentary lifestyle. Fibroblast growth factor 21
(FGF21) has recently emerged as a promising therapeutic candidate for the
treatment of obesity and diabetes. FGF21 is a starvation-induced pleiotropic
hormone with various beneficial metabolic effects, and pharmacological treatment
in rodents has been shown to improve insulin sensitivity and decrease simple
fatty liver disease. However, its effects on reversing the symptoms of advanced
liver disease have yet to be validated. Here, we investigated the protective
effects of the LY2405319 compound, an engineered FGF21 variant, in a
non-alcoholic steatohepatitis (NASH) model using leptin-deficient ob/ob mice and
a methionine- and choline-deficient (MCD) diet to induce steatohepatitis.
LY2405319 treatment in ob/ob mice corroborated previous results showing that
improvements in the metabolic parameters were due to increased mitochondrial
oxygen consumption rate and fatty acid oxidation. LY2405319 treatment in ob/ob
mice on an MCD diet significantly reduced the symptoms of steatohepatitis, as
confirmed by Masson's trichrome staining intensity. Serum levels of AST and ALT
were also reduced, suggesting an attenuation of liver injury, while detection of
inflammatory markers showed decreased mRNA expression of TGF-?1 and type-I
collagen, and decreased phosphorylation of NF-kB p65, JNK1/2, and p38.
Collectively, these data show that LY2405319 treatment attenuated MCD
diet-induced NASH progression. We propose that the LY2405319 compound is a
potential therapeutic candidate for the treatment of advanced liver disease.
