摘要 目的:观察连接蛋白43(CX43)、波形蛋白(Vimentin)在乳腺癌组织中的表达,探讨两者与乳腺癌转移之间的关系。方法:收集112例乳腺癌组织及30例癌旁正常乳腺组织,应用免疫组织化学法、westernblot法分别检测CX43、Vimentin的表达,并进行相关性分析。结果:免疫组织化学:(1)癌旁正常乳腺组织与乳腺癌组织中CX43的阳性表达率分别是86.7%和40.2%,而Vimentin的阳性表达率分别是20.0%和72.3%,表达差异均有统计学意义(P<0.05),且CX43与Vimentin的表达差异成负相关性(χ2=17.014,P=0.000<0.05,r=-0.226,P=0.017<0.05)。(2)CX43(-)/Vimentin(+)组与CX43(+)/Vimentin(-)组比较,淋巴结转移率较高(χ2=9.391,P=0.002<0.05)。(3)CX43表达与病理分级、TNM分期和转移成负相关(P<0.05),而Vimentin的表达与三者成正相关(P<0.05)。WesternBlot:CX43、Vimentin在正常、无淋巴结转移及有淋巴结转移的乳腺组织中的表达差异有统计学意义(P<0.05),有淋巴结转移的乳腺癌组织CX43的表达量最低而Vimentin的表达量最高。结论:CX43表达量的降低与Vimentin表达量的升高可能与乳腺癌转移有关,CX43、Vimentin联合检测可能对筛选乳腺癌高转移患者有一定的意义。
