| 摘 要： | 目的 探讨肝细胞癌(HCC)组织Glypican3(GPC3)和Sonic Hedgehog(Shh)蛋白表达及其功能分析。方法 取96例HCC患者癌组织和癌旁肝组织,体外培养HepG2、MHCC97H、Huh7和SMMC7721细胞,采用免疫组织化学染色法检测组织GPC3和Shh蛋白表达水平,采用免疫荧光染色和蛋白印迹法检测体外培养的肝癌细胞GPC3和Shh蛋白表达,应用String数据库预测GPC3和Shh蛋白之间相互作用。结果 在96例HCC癌组织,GPC3和Shh阳性率分别为77.1%和68.8%,而两种蛋白高表达率分别为60.4%和53.1%;高分化HCC癌组织GPC3蛋白阳性率为85.7%,显著高于低分化组的50.0%(P<0.05), Shh蛋白阳性率为81.0%,显著高于低分化组的40.0%(P<0.05);存在微血管侵犯(MVI)的HCC癌组织GPC3蛋白阳性率为72.7%,显著高于无MVI组的50.0%(P<0.05),Shh蛋白阳性率为65.9%,显著高于无MVI组的42.3%(P<0.05);体外培养的HepG2、MHCC97H、Huh7和SMMC7721四种肝癌细胞胞浆GPC3和Shh蛋白共表达,两种蛋白表达趋势一致。结论 GPC3和Shh蛋白可能影响HCC肿瘤细胞分化和MVI形成,并且两种蛋白可能存在共表达及相互作用。

| Abstract: | Objective The aim of this study was to investigate the cancerous expression and functional relations of glypican3(GPC3)and sonic Hedgehog(Shh)proteins in patients with hepatocellular carcinoma(HCC)and hepatoma cell lines in vitro.Methods The expression of GPC3 and Shh in cancerous and adjacent noncancerous tissues in 96 patients with HCC,and in HepG2,MHCC97H,Huh7 and SMMC7721 cells was assayed by immunochemical staining or by immunofluorescence staining and Western blotting.Results The positive rates of GPC3 and Shh protein expression were 77.1%and 68.8%,and the strong expression were 60.4%and 53.1%in our 96 patients with HCC;the positive rate of GPC3 protein in well-differentiated cancerous tissues was significantly higher than that in poorly-differentiated HCC(85.7%vs.50.0%,P<0.05),and the positive rate of Shh protein was significantly higher than that in poorly-differentiated HCC(81.0%vs.40.0%,P<0.05);the positive rate of GPC3 protein in cancerous tissues in patients with microvascular invasion(MVI)was significantly higher than that in those without(72.7%vs.50.0%,P<0.05),and the positive rate of Shh protein was significantly higher than that in those without(65.9%vs.42.3%,P<0.05);the GPC3 and Shh proteins were consistently co-expressed in the cytoplasm of hepatoma cells in vitro.Conclusion The GPC3 and Shh proteins might affect the differentiation of hepatoma cells and or the MVI formation,and the two proteins might interact each other in the carcinogenesis. |
