摘要
目的探讨血管紧张素Ⅱ(angio(ensin Ⅱ,AngII)对人肺成纤维细胞(huminlungfibroblast,HLF)细胞株HLF-1 I型胶原蛋白表达的影响。方法体外培养HLF-1细胞。采用Masson染色法检测HLF-1细胞总胶原蛋白的表达,采用Westernblot法检测HLF-1细胞I型胶原蛋白的表达。结果AngⅡ呈时间依赖性地促进HLF-1细胞总胶原蛋白及工型胶原蛋白的表达,并且在AngⅡ作用24h时达到峰值。结论Angl参与了HLF-1胶原合成的调控,并可能在肺纤维化的发生、发展中起重要作用。
Objective To explore the effect of angiotensin Ⅱ (Ang Ⅱ ) on the expression of collagen type I (col- I ) in humanlung fibroblast (HLF). Methods The HLF-1 cell line was used for in vitro studies. The total collagen protein expression level was detected using Masson staining assay. Col- I protein expression level was detected using Western blot. Results The expression levels of total collagen protein and Col-I protein were increased after Ang Ⅱ treatment in a time-dependent fashion. Conclusions Ang Ⅱ is involved in collagen synthesis in HLF-1 cell line.
