The molecular mechanisms involved in the development and progression of colorectal cancer (CRC) are not completely understood. The present study aimed to identify potential novel genes involved in the development and progression of CRC. Database analysis revealed that the mRNA level of the chloride channel accessory 4 (CLCA4) was frequently lower in primary tumor tissues compared with that in corresponding non-cancerous colon tissues, and was even lower in liver metastases than in primary tumors. Further analyses through The Human Protein Atlas (THPA) website and immunohistochemistry (IHC)-based tissue microarray (TMA) confirmed that CLCA4 mRNA and protein expression were downregulated in CRC tissues. Furthermore, IHC-based TMA analysis revealed a gradual decrease in CLCA4 protein expression among colorectal normal, adenoma and carcinoma tissues. Survival analysis revealed that the decrease in CLCA4 mRNA expression was associated with the overall survival rate of patients with different types of tumor, including CRC, breast cancer, head and neck cancer and stomach cancer. Overall, downregulated CLCA4 expression may influence the development and progression of CRC.
