Research Abstract |
We hypothesized that thrombin inactivation ameliorate cardiac remodeling and diabetes. Angiotensin II accelerated cardiac concentric remodeling and larger left atrial volume with prominent interstitial fibrosis in heparin cofactor II(HCII), an endogenous thrombin inhibitor,-deficient mice than those in wild-type mice. And these cardiac phenotypes were caused by enhancement of NAD(P) H oxidase-transforming growth factor-beta1 pathway. In addition, we found that increased thrombin activity in adipose tissue contributes to the development of insulin resistance via enhancing MCP-1 production, leading to macrophage infiltration and insulin receptor substrate-1-Akt pathway inactivation.
