摘要: 目的:探讨嗜酸性粒细胞趋化因子-1(Eotaxin-1)在肾透明细胞癌(ccRcc)中的表达情况及其与肿瘤增殖能力的关系。方法:免疫组织化学检测58例肾透明细胞癌患者肾癌组织及癌旁组织中Eotaxin-1以及增殖细胞核抗原(PCNA)的表达并分析其与肾癌临床病理特征的关系;用Western blotting法分析10例相互配对肾癌组织、癌旁组织中Eotaxin-1及PCNA的表达,并对Eotaxin-1与PCNA做相关性分析。结果:Eotaxin-1主要表达于胞浆,PCNA主要表达于细胞核内,Eotaxin-1和PCNA在肾癌组织的阳性率明显高于癌旁组织(P<0.05);病理分级为2-3级组的Eotaxin-1及PCNA阳性率显著高于病理分级为1级组(P<0.01)。临床分期为Ⅲ/Ⅳ组的Eotaxin-1及PCNA阳性率显著高于临床分期Ⅰ/Ⅱ组(P<0.05), 有淋巴结转移组的Eotaxin-1及PCNA阳性率高于无淋巴结转移组(P<0.05);10 例肾癌组织中Eotaxin-1及PCNA蛋白水平显著高于癌旁组织(P<0.01,P<0.05);Eotaxin-1与PCNA在肾癌组织中的表达存在相关性(P<0.05)。结论:肾透明细胞癌组织中Eotaxin-1与肾透明细胞癌的增殖能力密切相关,对Eotaxin-1的研究可能为临床对肾透明细胞癌诊断治疗提供新的思路。

Abstract: Objective To investigate the expression of Eotaxin-1 in clear cell renal cell carcinoma(ccRCC) and its relationship with tumor proliferation. Methods The Eotaxin-1 and PCNA expression from 58 tissues of ccRCC and para carcinoma were analysised by immunohistochemistry or western blot. Results Eotaxin-1 were mainly expressed in the cytoplasm while PCNA were expressed in the cell nucleus, positive rate of Eotaxin-1 and PCNA in ccRCC tissues was significantly higher than that in para carcinoma tissues(P<0.05), positive rate of Eotaxin-1 and PCNA in pathologic stageⅡ/Ⅲ was significantly higher than that in pathologic stageⅠ(P<0.01). The positive rate of Eotaxin-1 and PCNA in clinical stage Ⅲ/Ⅳ was significantly higher than that in clinical stageⅠ/Ⅱ(P<0.05). The protein level of Eotaxin-1 and PCNA in ccRCC were significantly higher than that in para-carcinoma tissues(P<0.01,P<0.05), Eotaxin-1 was positively related to PCNA in ccRCC tissues(P<0.05). Conclusion Eotaxin-1 was related to proliferation in ccRCC and was expected to be a clinical indicator for ccRCC.
