硫酸锌对血管内皮细胞氧化应激保护作用的研究
Effects of Zinc sulfate on preventing vascular endothelial cells from oxidative stress
摘要
Abstract
Objective:To investigate the effects of Zinc sulfate on preventing human umbilical veins endothelial cells ( HUVECs) from oxidative stress. Methods:Hydrogen peroxide was used to stimulate HUVECs to build the oxidative stress model in vitro. HUVECs were divided into normal group, H2 O2 group, Zinc sulfate group and Zinc sulfate treated group. Method of nitrate reductase was used to detect the content of nitric oxide ( NO ) and ELISA was used to detect the content of endothelin ( ET ) in supernatant in different groups. The level of HO-1,SOD and CAT of HUVECs were measured by Western blot. Apoptosis of HUVECs was examined by TUNEL as well. Results: Zinc sulfate could enhance the content of NO and decrease the content of ET in the supernatant,which induced by hydrogen peroxide on HUVECs. Zinc sulfate could also increase the level of HO-1, SOD and CAT obviously and decrease the apoptosis cells significantly induced by H2 O2 . Conclusion: Zinc sulfate play an important role in resisting oxidative stress in HUVECs, and maybe prevent HUVECs from oxidative stress damage. Zinc sulfate is expected to be an effective medicine on improving endothelial cells anti-oxidative ability.关键词
