目的:研究索拉菲尼对肝星状细胞( HSC )活性及活化的影响及作用机制。方法:分别将1、2、5、10μmol/L索拉菲尼培养液作用于LX2细胞,通过MTT检测观察不同浓度索拉菲尼对LX2细胞增殖的影响,应用免疫细胞化学染色法检测LX2细胞α-SMA的表达,ELISA法检测LX2细胞上清中PDGF-BB和TGF-β1水平变化, Western blot法检测各组LX2细胞PDGF信号通路各蛋白表达情况。结果:各组、各时间点LX2细胞增殖抑制率比较,差异均有统计学意义(F组间=1045.010,F时间=279.740,F交互=20.130,P均<0.001)。各组α-SMA的表达情况比较,差异有统计学意义(H=35.630,P<0.001)。各组、各时间点PDGF-BB和TGF-β1水平比较,差异均有统计学意义( P均<0.05)。实验组与对照组中ERK1、ERK2、AKT的表达基本相同,但在10μmol/L索拉菲尼干预后,各磷酸化蛋白表达降低。结论:索拉菲尼可抑制HSC的增殖及活化。

To investigate effects and mechanisms of sorafenib on hepatic stellate cell ( HSC) viability and acti-vation.Methods:LX2 cells were cultured with 1,2,5,10 μmol/L sorfenib and detected with MTT assay at different time respectively .Expression of α-SMA was measured immunocytochemically in LX 2 cells treated with different concentrations of sorafenib.Changes in PDGF-BB and TGF-β1 concentrations were detected in LX2 supernatant using ELISA .Expression of ERK1 , ERK2 and AKT signaling pathways was measured using Western blot assay .Results:After treatment with various concentrations of sorafenib for different times , the LX2 inhibition rate increased gradually ( Fgroup =1 045.010, Ftime =279.740,Finteraction =20.130,P<0.001).α-SMA expression treated with sorafenib became weaker than that in control group(H=35.630,P<0.001).PDGF-BB and TGF-β1 concentrations decreased with the increasing of sorafenib concen-tration and time exposured(P<0.05).ERK1, ERK2 and AKT expression was identical between experimental and control groups, but their phosphorylated expression decreased with increased concentrations of sorafenib , especially in 10 μmol/L sorafenib group .Conclusion:Sorafenib could suppress HSC proliferation and activation .
