Expressions of Cat B and Cys C in the Esophageal Carcinoma
Pages: 185-188
Year: Issue:  3
Journal: Journal of Basic and Clinical Oncology

Abstract: 目的 探讨组织蛋白酶B(Cat B)和半胱氨酸蛋白酶抑制剂C(Cys C)在食管癌组织中的表达及临床意义.方法 采用免疫组化及荧光定量PCR对56例食管癌及相对应的癌旁正常食管黏膜组织中Cat B和Cys C表达进行检测.结果 与癌旁正常食管黏膜组织比较,食管癌组织中Cat B和Cys C的mRNA和蛋白表达均明显上调(P<0.05).Cat B和Cys C的表达显著正相关(rs=0.970,P<0.05).Cat B 和Cys C的表达均与淋巴结转移有关,Cys C的表达还与肿瘤侵袭程度有关(P<0.05).结论 Cat B和Cys C在食管癌组织中均呈高表达,且其高表达与肿瘤恶性程度相关,有望成为食管癌早期诊断及预后判断的分子标志物.
