| Research Abstract |
We tried to prepare mutant FGF19 protein (FGF19-7) that lacks the activity of cell proliferation. FGF19-7 treatment slightly decreased CYP7A1 mRNA levels in HepG2 cells. Treatment of mice with FGF19-7 did not stimulate the number of Ki-67 positive cells that is a marker of cell proliferation. Mice were fed a methionin- and choline- deficient (MCD) diet for 6 weeks and co-treated with FGF19 or FGF19-7 (40 nmol/kg) for 4 days. Serum ALT and hepatic triglyceride and free fatty acid levels were markedly increased in mice fed MCD diet. These levels were significantly decreased in the mice co-treated with FGF19 or FGF19-7 to a similar extent. These results suggest that treatment with FGF19-7 lacking the activity of cell proliferation protects against MCD diet-induced steatohepatitis.
