Research Abstract

Presentation of hepatitis C virus - related liver tumor was found that activation of nuclear receptor: PPAR exerts as an essential factor. In this study, several attempts to prevent occurrence of liver tumor by means of PPAR antagonist (MK886) etc. were done, using transgenic mice expressing hepatitis C virus core protein. Administration of high dose MK886 (40 mg/kg/day) was confirmed to completely prevent occurrence of liver tumor, however, MK886 could cause fatal toxicity in some mice.
