目的:探讨补体反应基因-32( RGC-32)与锌指E盒结合蛋白( ZEB1)在胃癌组织中的表达及意义。方法应用免疫组化S-P法分别检测60例胃癌、,60例癌前病变、20例正常胃黏膜组织中RGC-32和ZEB1蛋白的表达情况。结果 RGC-32在胃癌、癌前病变及正常胃黏膜组织中的阳性表达率依次降低,分别为78.3%、41.7%、40.0%(P<0.05)。ZEB1在胃癌、癌前病变及正常胃黏膜组织中的阳性表达率亦依次降低,分别为88.3%、50.0%、20.0%(P<0.05)。胃癌组织中RGC-32和ZEB1的表达与胃癌的病理分化程度、TNM分期和淋巴结转移有关( P<0.05)。胃癌组织、癌前病变组织中的RGC-32与ZEB1表达均呈正相关关系(r=0.568、0.452,P<0.05)。结论 RGC-32、ZEB1的异常表达可能促进胃癌的发生、发展和浸润转移,两者可能作为胃癌诊断和预后判断的指标,有可能成为胃癌治疗的新靶点。
目的:探討補體反應基因-32( RGC-32)與鋅指E盒結閤蛋白( ZEB1)在胃癌組織中的錶達及意義。方法應用免疫組化S-P法分彆檢測60例胃癌、,60例癌前病變、20例正常胃黏膜組織中RGC-32和ZEB1蛋白的錶達情況。結果 RGC-32在胃癌、癌前病變及正常胃黏膜組織中的暘性錶達率依次降低,分彆為78.3%、41.7%、40.0%(P<0.05)。ZEB1在胃癌、癌前病變及正常胃黏膜組織中的暘性錶達率亦依次降低,分彆為88.3%、50.0%、20.0%(P<0.05)。胃癌組織中RGC-32和ZEB1的錶達與胃癌的病理分化程度、TNM分期和淋巴結轉移有關( P<0.05)。胃癌組織、癌前病變組織中的RGC-32與ZEB1錶達均呈正相關關繫(r=0.568、0.452,P<0.05)。結論 RGC-32、ZEB1的異常錶達可能促進胃癌的髮生、髮展和浸潤轉移,兩者可能作為胃癌診斷和預後判斷的指標,有可能成為胃癌治療的新靶點。

Objective Toinvestigatetheexpressionsandsignificanceofresponsegenetocomplement-32(RGC-32)andzinc-fingerE-box-bindinghomeoboxfactor1(ZEB1)inthegastriccarcinoma.Methods Ⅰmmunohisto-chemistry S-P method was used to detect the RGC-32 and ZEB1 expressions in the 60 specimens of gastric carcino-ma,60specimensofprecancerouslesionand20specimensofnormalgastricmucosa.Results Theexpressionrate of RGC-32 in the gastric carcinoma,precancerous lesion,and normal gastric mucosa were 78. 3%,41. 7% and 40. 0%,respectively(P<0. 05). The expression rate of ZEB1 in the gastric carcinoma,precancerous lesion,and normal gastric mucosa were 88. 3%,50. 0% and 20. 0%,respectively(P<0. 05).Ⅰn the gastric carcinoma,the RGC-32 and ZEB1 expressions were related to differentiated degree,TNM stage and lymph-node metastasis(P<0. 05). Po-sitive correlation was build up between the RGC-32 and ZEB1 expressions in the gastric carcinoma(r=0. 568,P<0.05)andprecancerouslesion(r=0.452,P<0.05).Conclusion RGC-32andZEB1maypromotethedevelop-ment,infiltration and metastasis of gastric carcinoma,RGC-32 and ZEB1 are possible molecular markers of gastric carcinoma,may be used in the diagnosis and prognosis,and can be as the therapeutic targets of gastric carcinoma.
