【摘要】 目的探讨川芎嗪对HSC-T6细胞Smad蛋白细胞内转位的影响。方法在HSC-T6细胞培养皿中加入10-5mol/L川芎嗪培养2h,然后采用免疫荧光法检测HSC-T6细胞内Smad-2和Smad-4蛋白细胞内转位。结果经过川芎嗪作用2h后,未发现Smad-2和Smad-4蛋白在HSC-T6细胞内出现转位。结论川芎嗪作用于细胞时可能阻断TGF-β/Smad的细胞内信号转导,这可能是其抑制HSC细胞增殖的重要机制之一。更多还原

【Abstract】 Objective To investigate the effect of ligustrazine on the intracellular translocation of Smad protein in HSC-T6 cell line.Methods HSC-T6 cell was cultured with ligustrazine at the dose of 10-5 mol/L in the culturing dish for 2 hours.After the culturing,the translocation of Smad-2 and Smad-4 proteins was detected by immunofluorescence assay.Results There was no evidence of the translocation of Smad-2 and Smad-4 proteins in HSC-T6 cell after the culturing.Conclusion Ligustrazine can block the signal pathway of TGF-β/Smad,which may be one of its important mechanisms of inhibiting the proliferation of HSC-TS cell.更多还原
