Long non-coding RNA(lncRNA)is a class of transcripts with a length of more than 200 nucleotides.It is
involved in the occurrence and development of tumors and plays an important role by regulating the expression and function of DNA,RNA and protein.In recent years,lncRNA has become a new research direction for early diagnosis and prognosis of malignant tumors.As a newly discovered lncRNA,linc-UBC1 is abnormally highly expressed in a variety of malignant tumors such as lung cancer,gastric cancer,colorectal cancer,cervical cancer,ovarian cancer,and esophageal squamous cell carcinoma.It can promote the proliferation,migration,invasion,cell cycle progression,cell apoptosis and EMT of tumor cells by acting as a competing endogenous RNA(ceRNA)and participating in signaling pathways.High expression of linc-UBC1 can increase the drug resistance of malignant tumors,and its expression level is positively correlated with tumor stage,lymph node metastasis and distant metastasis of primary tumors.linc-UBC1 is expected to become a new biomarker,prognostic predictor and therapeutic target for many malignant tumors,while its specific regulatory mechanism is still in the early stage of research and needs further in-depth study.This article reviews the current research progress of linc-UBC1 in the occurrence and development of malignant tumors.
