Objective To explore whether angiotensin-(1-7) [Ang-(1-7)] protects cardiac myocytes against high glucose(HG)-induced injury by inhibiting ClC-3 chloride channels. Method H9c2 cardiac cells were exposed to 35 mmol/L glucose for 24 h to establish a cell injury model. The cells were treated with Ang-(1-7) or the inhibitor of chloride channel(NPPB) in the presence of HG for 24 h to observe the changes in HG-induced cell injury. Cell counter kit 8(CCK-8) assay was used to test the cell viability, and the morpho...
