活血补肾安神方对氧化应激损伤H9c2心肌细胞能量代谢的影响
Effects of Huoxue Bushen Anshen Prescription on Energy Metabolism of H9c2 Cardiomyocytes with Oxidative Stress Injury
摘要
Abstract
Objective To observe the effects of Huoxue Bushen Anshen Prescription on energy metabolism of H9c2 cardiomyocytes with oxidative stress injury.Methods H9c2 cardiomyocytes oxidative stress model was established with H2O2 to simulate myocardial injury.CCK-8 method was used to select the best conditions for modeling and the appropriate concentration of drugs.Cells were divided into normal group,model group,trimetazidine hydrochloride group and Huoxue Bushen Anshen Prescription group.Na+-K+-ATPase activity,real-time ATP generation rate,mitochondrial pressure,gycolysis rate,and long-chain fatty acid oxidationl pressure on H9c2 cardiomyocytes after treatment were performed,and the changes in energy metabolism of cardiomyocytes were observed.Results Compared with the normal group,the Na+-K+-ATPase activity,glycolytic ATP production rate,mitochondrial ATP production rate,basal oxygen consumption,non mitochondrial oxygen consumption,ATP production capacity,cellular reserve respiratory capacity and maximum respiratory capacity of H9c2 cells in the model group decreased,the glycolytic rate slowed down,long chain fatty acid basal respiration,acute response and maximum respiratory value decreased(P<0.05,P<0.01).Compared with the model group,the H9c2 cells in Huoxue Bushen Anshen Prescription group showed an increase in Na+-K+-ATPase activity,an increase in glycolytic ATP production rate and mitochondrial ATP production rate,an increase in basal oxygen consumption,non mitochondrial oxygen consumption,ATP production capacity,cellular reserve respiratory capacity and maximum respiratory capacity,an increase in basal glycolysis rate,and an increase in long-chain fatty acid basal respiration,acute response and maximum respiratory value(P<0.05,P<0.01).Conclusion Huoxue Bushen Anshen Prescription can significantly improve the activity of Na+-K+-ATPase in cH9c2 ardiomyocytes with oxidative stress injury,increase the rate of ATP production,improve mitochondrial pressure,glycolysis rate and oxidation pressure of long chain fatty acids,and improve the energy metabolism of cardiomyocytes.关键词
