| Outline of Final Research Achievements |
In order to investigate the metabolic roles of MUP1 in obesity development, we generated the transgenic mice that overexpress MUP1 under the control of CAG promoter (MUP1-TG mice). Expression of MUP1 was very high in various tissues, including adipose tissue, of MUP1-TG mice compared to those of wild-type mice. Overexpression of MUP1 protected short-term high-fat diet (HFD)-induced lipidemia and body weight gain with increasing adipose tissue mass. In vitro model of adipocyte differentiation using mouse embryonic fibroblasts, overexpression of MUP1 suppressed the mRNA levels of adipocyte-related genes in the early stage, and prevent lipid droplet accumulation. Furthermore, the protection of HFD-induced lipidemia and body weight gain in MUP1-TG mice was attenuated by heterozygous peroxisome proliferator-activated receptor γ knockouts. Our findings suggest a novel role of MUP1 which may maintain metabolic homeostasis by regulation of adipocyte differentiation in the early stage.
