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.
