| 摘 要： | 目的 探讨肝细胞癌(HCC)组织衣被蛋白复合体亚基β2(coatomer protein complex subunit beta 2,COPB2)基因水平变化及其临床意义。方法 在113例HCC患者,采取肝癌切除术治疗,取癌组织和癌旁肝组织,采用RT-PCR法检测COPB2 mRNA水平,采用Western blot法和免疫组化法检测COPB2蛋白表达水平。建立多变量COX比例风险回归模型分析影响HCC患者预后的独立危险因素。结果 HCC组织和癌旁肝组织COPB2基因mRNA水平分别为1.32±0.40和0.47±0.14,差异具有统计学意义(P=0.013),两者COPB2蛋白相对表达水平分别为1.35±0.56和0.44±0.12,也具有显著性统计学差异(P=0.035);本组癌组织COPB2蛋白高表达45例(39.8%),低表达或阴性68例(60.2%);有无HBV感染、术前血清AFP水平、不同肿瘤结节数目、肿瘤分化程度和有无血管浸润患者癌组织COPB2蛋白表达强度不同(P＜0.05);本组113例患者死亡68例(59.8%),生存时间为(1047.0±167.7) d,中位生存时间1046 d;COPB2蛋白高表达组平均生存时间为(747.3±116.3) d,中位生存时间为610 d,COPB2蛋白低表达组平均生存时间为(1673.7±213.5) d,中位生存时间为1462 d(P=0.001);多因素Cox比例风险回归模型分析结果显示,术前血清AFP水平、血管浸润、肿瘤结节数目和肝癌组织COPB2表达水平是影响 HCC患者总生存时间的独立影响因素(P<0.05)。结论 HCC患者癌组织COPB2过表达可能预示不良预后,该基因及其蛋白表达可能与肿瘤细胞侵袭转移密切相关,COPB2可能成为预警HCC患者不良预后的一个新的分子标志物并可能成为潜在的治疗靶点。

| Abstract: | Objective The aim of this study was to investigate the expression of coatomer protein complex subunit beta 2(copb2)gene in cancerous tissues in patients with hepatocellular carcinoma(HCC)and its relationship with prognosis.Methods 113 patients with HCC underwent hepatectomy,and the COPB2 mRNA and its protein expression in cancerous and adjacent noncancerous tissues were detected by RT-PCR and Western bloting as well as immunohistochemistry.The multivariate Cox proportional risk regression model was established to analyze the independent risk factors affecting the prognosis of patients with HCC.Results The COPB2 mRNA in cancerous and noncancerous tissues were(1.32±0.40)and(0.47±0.14),significantly different between them(P=0.013),and the COPB2 protein expression were(1.35±0.56)and(0.44±0.12),also significantly different between them(P=0.035);the strong cancerous COPB2 expression was found in 45 patients(39.8%),while the weak or negative expression was found in 68 patients(60.2%);the expression of COPB2 was found much different in patients with or without HBV infection,with different serum AFP levels,different tumor foci,different tumor cell differentiation,and with or without tumor invasion(P<0.05);68 patients(59.8%)died in our series at the end of follow-up,with the survival time of(1047.0±167.7)days;the survial time in patients with strong cancerous COPB2 expression was(747.3±116.3)days,much shorter than(1673.7±213.5)days in patients with weak or negative COPB2 expression(P=0.001);the multivariate Cox proportional risk regression model showed that the cancerous COPB2 expression,serum AFP levels,tumor invasion and tumor foci were the independent risk factor for overall survival of patients with HCC.Conclusion The up-regulation of COPB2 expression in cancerous tissues in patients with HCC might hint the bad prognosis after hepatectomy,which warrants further investigation. |
