Long noncoding RNAs (lncRNAs) are a class of RNA molecules that are greater than 200 nt in length and do not have protein-coding capabilities or encode micropeptides only. LncRNAs are involved in the regulation of cell proliferation, differentiation, apoptosis and other biological processes, and are closely associated with the occurrence, recurrence and metastasis of a variety of malignant hematologic diseases. This article summarizes the function, regulatory mechanism and potential clinical application of lncRNAs in leukemia. In general, lncRNAs regulate the occurrence and development of leukemia and the multi-drug resistance in chemotherapy through epigenetic modification, ribosomal RNA transcription, competitive binding with miRNA, modulating glucose metabolic pathway, and activating tumor-related signaling pathway. Studies on lncRNAs provide new references for understanding the pathogenesis of leukemia, uncovering new prognostic markers and potential therapeutic targets, and addressing the problems of drug resistance and post-treatment recurrence in patients in clinical treatment of leukemia.
