TNF-α对兔胆管成纤维细胞P311/TGF-β1/α-SMA通路的影响及川芎嗪的干预作用
发布时间:2020-12-18 09:03
目的:探讨TNF-α对兔胆管成纤维细胞P311/TGF-β1/α-SMA通路的影响及川芎嗪的干预作用。方法:分离、培养正常家兔胆管成纤维细胞并鉴定,将胆管成纤维细胞分别给予TNF-α、TNF-α联合不同浓度的TMP(0.08、0.4、2.0 mg/m L)干预48 h,以无处理的胆管成纤维细胞为空白对照,用CCK-8法检测细胞增殖水平;real-time PCR检测细胞P311、TGF-β1、α-SMA m RNA表达;Western blot检测细胞TGF-β1、α-SMA蛋白表达。结果:与空白对照比较,胆管成纤维细胞经TNF-α处理后,增殖明显增强,P311、TGF-β1、α-SMA m RNA以及TGF-β1、α-SMA蛋白表达明显上调(均P<0.05);TMP对TNF-α的上述效应有抑制作用,并且呈现浓度依耐趋势,其中0.4、2.0 mg/m L的TMP有明显作用(均P<0.05)。结论:TNF-α可能通过调控P311/TGF-β1/α-SMA信号通路促进胆管成纤维细胞增殖,TMP能抑TNF-α对该通路的活化,故可能对良性胆道狭窄有防治作用。
