Abstract:
Objective:To study the relationship between hepatic tissue insulin receptor substrate 2(IRS2) gene and type 2 diabetes,and the regulation of acupuncture on IRS2 gene expression of hepatic tissue in type 2 diabetes mellitus(T2DM) rats.Methods:Obese rats due to diet were injected in abdomen with small dose streptozotocin(STZ) to induce T2DM.Then these T2DM rats were stochastically divided into acupuncture group,Glibenclamide group and model group.After 4 weeks treatment,fasting blood sugar(FBS) was examined with active blood sugar meter,fasting insulin(FINS) was examined by radioimmunoassav,hepatic tissue IRS2mRNA was evaluated in real-time RT PCR,and normal rats were in control.Results:Serum levels of FBS(15.79?1.87) and FINS(37.20?3.92) in model group were higher than those in normal group(5.16?0.13,23.57?1.63),serum levels of FBS(5.46?0.20) and FINS(20.87?1.80) in acupuncture group were obviously lower than those in model group,which were similar to normal group.FBS(5.26?0.13) reduced obviously and serum FINS(28.10?1.86) reduced in some degree in Glibenclamide group compared with model.Relative contents of IRS2mRNA in model group were 2.19 folds compared with that in normal group.And in Glyburide group it was 4.59 folds compared with that in normal group.In acupuncture group it was 4.04% of that in the normal group.Conclusion:Abnormal hepatic tissue IRS2 mRNA expression may be one of pathogenesis of T2DM.Acupuncture can obviously depress hepatic tissue IRS2 mRNA expression,but Glibenclamide can not.
