| Outline of Final Research Achievements |
In this study, we examined how CREBH is involved in lifestyle-related diseases, especially on the development and progression of nonalcoholic fatty liver. CREBH liver-specific KO (LKO) mouse using CRISPR/Cas9 system was successfully produced. The mouse exhibited a remarkable increase in blood lipids upon fasting. One of the causes is the increase of the transcription factor SREBPs which govern the expression of fatty acid and cholesterol synthesis genes. When LKO mice were fed with methionine choline deficient diet, which is a nonalcoholic fatty liver model, severe liver injury appeared in the early period. In this study, we have established a method for preparing new genetically modified mice, and clarified that deficiency of CREBH induces nonalcoholic fatty liver.
