Research Abstract

Recently patients with non-alcoholic steatohepatitis (NASH) have been increased because of westernization of lifestyle in Japan, which evokes a serious problem in the society. The goal of the present study is to elucidate the difference in the regeneration mechanisms between NASH and normal livers using NASH animal models. Investigation for a long period observation of two NASH model mouse candidates proved that feeding of choline deficient amino acid diet to wild-type mice is appropriate to evoke NASH. Liver regeneration is significantly impaired in NASH liver compared with normal liver after 70% partial hepatectomy. Additionally the results by FACS analysis suggested the involvement of new blood cells in the delay of liver regeneration.
