摘要:

目的 探讨钙激活氯通道蛋白1(ANO1)和E-钙黏蛋白(E-cadherin)在结直肠癌(CRC)组织中的表达及其与CRC患者临床病理特征的关系,并阐明其临床意义。 方法 收集原发性CRC患者的手术组织样本77例。采用免疫组织化学(IHC)法检测CRC组织中ANO1和E-cadherin蛋白表达情况,采用Spearman相关分析法分析二者表达的相关性,采用PCR荧光探针法检测CRC组织中KRAS/NRAS突变情况,采用卡方检验或Fisher确切概率法分析ANO1和E-cadherin表达与CRC患者临床病理特征的关系。 结果 IHC法检测,CRC组织中ANO1阳性表达率为24.7%,E-cadherin阳性表达率为63.6%。Spearman法分析,CRC组织中ANO1与E-cadherin表达呈正相关关系(r=0.458,P<0.05)。肿瘤部位在结肠的CRC患者癌组织中ANO1阳性表达率明显高于肿瘤部位在直肠的患者(χ2=5.499,P=0.019);TNM分期Ⅰ-Ⅱ期CRC患者癌组织中ANO1阳性表达率明显高于Ⅲ-Ⅳ期的患者(χ2=4.774,P=0.029);无淋巴结转移的CRC患者ANO1阳性表达率明显高于有淋巴结转移的患者(P=0.034)。T1-T3期CRC患者E-cadherin阳性表达率明显高于T4期的CRC患者(P=0.024)。p53阴性、Ki-67<90%、PMS2阴性和KRAS突变型的CRC患者癌组织中ANO1阳性表达率明显高于p53阳性、Ki-67≥90%、PMS2阳性和KRAS野生型的CRC患者(P=0.031,P=0.036,P=0.048,P=0.028)。 结论 患者原发性CRC组织中ANO1与E-cadherin表达呈正相关关系,ANO1及E-cadherin与患者多个临床病理特征存在关联性,ANO1和E-cadherin可能参与CRC的发生和进展过程。

Abstract:

Objective To explore the expressions of calcium-activated chloride channel protein 1(ANO1) and E-cadherin in colorectal cancer (CRC) tissue and their relationships with the clinicopathological characteristics of the CRC patients, and to clarify their clinical significances. Methods The surgical tissue specimens from 77 patients with primary CRC were collected. Immunohistochemistry (IHC) method was used to detect the protein expressions of ANO1 and E-cadherin in CRC tissue; Spearman correlation analysis method was used to analyze the correlation between their expressions; PCR fluorescence probe method was used to detect the KRAS/NRAS mutations in CRC tissue; chi-square test or Fisher’s exact probability method was used to analyze the relationships between the expressions of ANO1 and E-cadherin and clinicopathological characteristics of the CRC patients. Results The IHC results showed that the positive expression rate of ANO1 in CRC tissue was 24.7%, and the positive expression rate of E-cadherin was 63.6%. The Spearman analysis results showed that the expressions of ANO1 and E-cadherin in CRC tissue were positively correlated (r=0.458, P<0.05). Compared with the patients with tumor located in rectum, the positive expression rate of ANO1 in cancer tissue of the CRC patients with tumor located in colon was significantly increased (χ2=5.499, P=0.019); compared with the patients with TNM stage Ⅲ-Ⅳ, the positive expression rate of ANO1 in cancer tissue of the CRC patients with TNM stage Ⅰ-Ⅱ was significantly increased (χ2=4.774, P=0.029); compared with the patients with lymphnode metastasis, the positive expression rate of ANO1 in the CRC patients without lymphnode metastasis was significantly increased (P=0.034). Compared with the CRC patients with T4 stage, the positive expression rate of E-cadherin in the CRC patients with T1-T3 stage was significantly increased (P=0.024). Compared with the CRC patients with p53 positive, Ki-67≥90%, PMS2 positive and KRAS wild-type, the positive expression rate of ANO1 in cancer tissue of the CRC patients with p53 negative, Ki-67<90%, PMS2 negative and KRAS mutant was significantly increased (P=0.031, P=0.036, P=0.048, P=0.028). Conclusion The expressions of ANO1 and E-cadherin in primary CRC tissue of the patients are positively correlated; ANO1 and E-cadherin are associated with multiple clinicopathological characteristics of the patients; ANO1 and E-cadherin may be involved in the occurrence and progression of CRC.
