On the basis of our findings, we propose selective FAP inhibition as a potential therapeutic approach to increase endogenous FGF21 activity for the treatment of obesity, type 2 diabetes, non-alcoholic steatohepatitis, and related metabolic disorders.
We also evaluated FGF21 serum levels and liver messenger RNA (mRNA) expression in nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH).
