               [摘   要] 长链非编码RNA(long noncoding RNA,LncRNA)是一类在基因调控中扮演重要角色的非编码RNA分子,长度超过
                200 nt,通常被认为不具备蛋白质编码能力。然而近年来大量研究发现,LncRNA具有一定的编码潜力,其短开放阅读框(short
                open reading frame,sORF)实际上可编码一些功能性的微肽。这些微肽在钙离子稳态、调节细胞器代谢、细胞分化等多种生物
                学过程中发挥重要作用,还可影响心血管疾病、炎症性疾病、恶性肿瘤等病理过程,尤其是可通过参与多种细胞信号通路影响
                肿瘤的发生、发展和转移。文章根据这些LncRNA编码肽参与的不同信号通路以及对肿瘤发生发展过程的影响,总结LncRNA
                编码肽在肿瘤信号通路中的研究进展,探讨其作为潜在的生物标志物和治疗靶点的可能性,同时也指出了当前研究的局限性
                以及未来的研究方向。

               [Abstract] Long noncoding RNA(LncRNA)is a class of non ⁃ coding RNA molecules,which plays an important role in gene
                regulation,with lengths exceeding 200 nucleotides,and is traditionally considered to lack protein ⁃ coding capacity. However,a
                substantial amount of recent research has revealed that LncRNA possesses coding potential,with its short open reading frame(sORF)
                capable of encoding functional micropeptides. These micropeptides play significant roles in various biological processes,including
                calcium ion homeostasis,regulation of cellular organelle metabolism,and cell differentiation. They can also impact pathological
                processes,such as cardiovascular diseases,inflammatory diseases,and malignant tumors,particularly by participating in multiple
                cellular signaling pathways that affect the occurrence,development,and metastasis of cancer. This review summarizes the research
                progress of LncRNA⁃encoded peptides in tumor signaling pathways,based on their involvement in different signaling pathways and
                their effect on the process of tumorigenesis and development. It discusses the potential of these peptides as biomarkers and therapeutic
                targets as well as points out the limitations of current research and the direction for future studies.
