Towards epigenetic understanding and therapy of insulin resistance by intranuclear insulin [mouse liver gene expression]

There is evidence indicating the involvement of DNA methylation memory in maintaining gene expression patterns associated with insulin resistance. Although the exact mechanism remains unknown, it has been proved that insulin resistance is correlated to low heat shock protein (HSP) expression. We reveal that intranuclear insulin can reduce HSP DNA methylation level to up-regulate HSP protein expression and result in long term cure of hyperglycemia. Type 2 diabetes KKAy mouse were selected in our experiments.Three conditions were compared with three replicates each. These are:(1) Untreated KKAy mouse (2) Insulin treated KKAy mouse(Insulin); (3) Biomineralized insulin treated KKAy mouse(BI).
