长链非编码RNA CCAT1与消化系统恶性肿瘤关系的研究进展

摘要

Long non-coding RNAs(lncRNAs)is a functional RNA molecule with a sequence length greater than 200 nucleo-tides that is not translated into a protein. LncRNA is of great value in the clinical application of malignant tumors and is closely related to the diagnosis,prevention,treatment and prognosis of tumors. CCAT1(human colon cancer associated transcript-1)can play a carci-nogenic role by promoting cell proliferation,invasion and migration. CCAT1 can be used as a biomarker for tumor prognosis. In this re-view,the research progress on the relationship between CCAT1 and digestive system malignant tumors is reviewed in recent years,the current status and prospects of malignant tumor treatment by CCAT1 are discussed.%长链非编码RNA(Long non-coding RNA,Lnc RNA)是序列长度大于200个核苷酸且不翻译成蛋白质的功能性RNA分子. LncRNA在恶性肿瘤的临床应用中有重大价值,与肿瘤的诊断、预防、治疗及预后有密切联系.人类结肠癌相关转移因子-1(Colon cancer associated transcript-1 CCAT1)可以通过促进细胞增殖、侵袭和迁移来发挥致癌作用,CCAT1可以作为肿瘤预后的生物标志物.本文就近年来人们对于CCAT1与消化系统恶性肿瘤关系的研究进展做一综述,并探讨通过CCAT1治疗恶性肿瘤的现状和前景.
