The incidence and mortality rate of digestive system tumors showed an increasing trend year by year, which seriously threatens human life and health. Recent years, studies have found that urothelial carcinoma embryonic antigen 1 (UCA1)is a long non-coding RNA (lncRNA), its expression significantly increased in a variety of digestive system tumor tissues or cells such as gastric cancer, colorectal cancer and esophageal cancer. In addition, UCA1 can interact with miRNAs to affect the proliferation,migration, invasion, epithelial-to-mesenchymal transition (EMT), apoptosis and drug resistance of tumor cells. The research progress of the action mechanism of lncRNA UCA1 and miRNAs in digestive system tumors (including gastric cancer, colorectal cancer and esophageal cancer) is reviewed, and the application of lncRNA UCA1 as a new biomarker and therapeutic target is prospected in present paper.
