We found that the mRNA and protein expression of PPARγ in hypothalamus of the T2DM-RSG rats increased than that in the T2DM rats, but not in the T2DM-RSG-EA group; furthermore, PPARγ was obviously decreased after electroacupuncture treatment compared with the T2DM-RSG rats (Figures 6(a) and 6(b) and Table 2). This evidence concerns the gene PPARG and type 2 diabetes mellitus.
