Abstract

Gastrodin (GAS) is the major component isolated from the rhizome of the Chinese traditional medicinal herb “Tianma.” Many clinical studies have found that GAS protects cardiomyocytes in cardiovascular diseases, although the effects and underlying mechanisms on cardiovascular anoxia/reoxygenation (A/R) injury remain unknown. This study is aimed at exploring the effect of gastrodin on cardiomyocytes in A/R injury. Our results suggested that the protective effect of GAS on cardiomyocytes is associated with upregulated 14-3-3η levels. Pretreatment with GAS could increase the cell viability and decrease the activities of creatine phosphokinase (CPK) and lactate dehydrogenase (LDH). GAS could also reduce reactive oxygen species (ROS) production, inhibit mitochondrial permeability transition pore (mPTP) opening, alter the maintenance of the mitochondrial membrane potential (∆Ψm), decrease the activation of caspase-3, and finally restrain cell apoptosis. Downregulating 14-3-3η levels by transfection with siRNA14-3-3η clearly attenuated the protective effect of GAS on cardiomyocytes in A/R injury.
