Outline of Final Research Achievements

Being obese raises the risk of developing type 2 diabetes and other associated health problems. For treatment of obesity, a large reduction in caloric intake, along with increased physical activity, can produce a loss body weight over. But control caloric intake is not easy for us. In this study, I challenged to find new biomarker for ‘evaluation of anti-obesity activity’ using adipocyte. I found that several proteasome inhibitors have suppression effect of adipogenic differentiation in 3T3-L1 preadipocytes. Furthermore, one of proteasome inhibitors is selectivity towards immunoproteasome. These findings suggest that understanding roles of immunoproteasome in chronic local inflammation in adipose tissue is important for our study.
