| 摘 要： | 目的:探讨法舒地尔对血小板源性生长因子(platelet-derived growth factor,PDGF)诱导的人肺动脉平滑肌细胞(human pulmonary artery smooth muscle cell,HPASMC)增殖的抑制作用及机制。方法:以体外培养的HPASMC为研究对象,PDGF-BB诱导增殖,法舒地尔进行预处理,MTT法检测细胞增殖;流式细胞仪检测细胞周期;Western blot检测增殖细胞核抗原(proliferating cell nuclear antigen,PCNA)和p27kip1蛋白的表达。结果:细胞培养24 h后与空白组比较,PDGF组HPASMC细胞增殖比例,S期细胞比例和PCNA蛋白表达明显增加,p27kip1蛋白表达则明显降低;用法舒地尔预处理后,与PDGF组比较,细胞增殖比例,S期细胞比例和PCNA蛋白表达明显下降,p27kip1蛋白表达则明显增加。结论:法舒地尔可通过上调p27kip1蛋白表达来抑制PDGF诱导的HPASMC增殖和细胞周期进程。 |

| Abstract: | Objective To investigate the inhibiting effect of Fasudil on platelet-derived growth factor-induced human pulmonary artery smooth muscle cell proliferation and its mechanism.Methods Human pulmonary artery smooth muscle cells were cultured with the stimulation of platelet-derived growth factor-BB,and Fasudil in different concentrations was added before the addition of mitogen.Cell number and cell viability were determined with a hemocytometer and MTT assay respectively.The expressions of PCNA and p27kip1 pro... |
