Outline of Final Research Achievements |
1) In ob/ob mice, M-mod/USP2A expression was clearly decreased in adipose tissue macrophages whereas aP2 and PAI were increased. Transgenic mice selectively expressing M-mod in macrophages did not exhibited significant changes in body weight gain, blood glucose levels, and blood insulin levels after high fat diet for 3 months. On the other hand, the M-mod transgenic mice displayed decreased accumulation of macrophages in visceral adipose tissues in parallel with decreased expression of chemokines in macrophages. In addition, M-mod overexpression in macrophages for 1 year caused decreased body weight gain and improved insulin sensitivity. Thus, M-mod seems to be a potent attenuator of type 2 diabetes. 2) M-mod knockdown macrophage-like cells modulated acetylation and methylation of histone near the M-mod-targeting genes such as aP2. Moreover, we found several nuclear proteins directly associated with M-mod in macrophages.
