羟基红花黄色素A抑制血管紧张素Ⅱ介导的心脏成纤维细胞肌化
Inhibition of angiotensin Ⅱ-mediated cardiac fibroblast myofibroblast transformation by hydroxy crocetin A
摘要
Abstract
Objective To study the effects of Hydroxysafflor yellow A(HSYA)on angiotensin Ⅱ(Ang-Ⅱ)-mediated myocar-dial fibrosis.Methods HFC-aa cells were randomly divided into the control group,the Ang-Ⅱ group,the Ang-Ⅱ+HSYA(5µM)group,the Ang-Ⅱ+HSYA(25µM)group,the Ang-Ⅱ+HSYA(50µM)group,and the Ang-Ⅱ+HSYA(100µM)group.Cells in the Ang-Ⅱ group were treated with 0.5µM Ang-Ⅱfor 24 hours,and cells in the Ang-Ⅱ+HSYA groups were treated with HSYA(5,25,50,and 100µM)and Ang-Ⅱ(0.5µM)for 24 hours.Cells in the control group were treated with the same volume of PBS.Cell wound healing and transwell migration assays were used to determine the cell migration.DCFH-DA fluorescent probe was utilized to de-tect the intracellular ROS level,and western blot was used to evaluate the protein expression of α-SMA,Collagen Ⅰ,Collagen Ⅲ and TGF-β1.Results Ang-Ⅱ could increase the migration and ROS production of cardiac fibroblasts.HSYA inhibited Ang-Ⅱ-mediated cardiac fibroblasts migration and ROS production.Western blot showed that HSYA inhibited Ang-Ⅱ-mediated protein expression of α-SMA,Collagen Ⅰ,Collagen Ⅲ and TGF-β1 in cardiac fibroblasts,and the difference was statistically significant(P<0.05).Con-clusion HSYA inhibited the differentiation of cardiac fibroblasts into myofibroblasts induced by Ang-Ⅱ by reducing the production of reactive oxygen species(ROS)and down-regulating the TGF-β1 signaling pathway.关键词
