MicroRNAs (miRs) are a class of single-stranded RNA molecules of 15-27 nucleotides in length that regulate gene expression at the post-translational level. miR-21 is one of the earliest identified cancer-promoting 'oncomiRs', targeting numerous tumor suppressor genes associated with proliferation, apoptosis and invasion. The regulation of miR-21 and its role in carcinogenesis have been extensively investigated. Recent studies have focused on the diagnostic and prognostic value of miR-21 as well as its implication in the drug resistance of human malignancies. The further use of miR-21 as a biomarker and target for cancer treatments is likely to improve the outcome for patients with cancer. The present review highlights recent findings associated with the importance of miR-21 in hematological and non-hematological malignancies.
微小RNA(miR)是一类长度为15 - 27个核苷酸的单链RNA分子,可在翻译后水平调节基因表达。miR - 21是最早被鉴定出的促癌“致癌miR”之一,靶向许多与增殖、凋亡和侵袭相关的肿瘤抑制基因。miR - 21的调控及其在致癌过程中的作用已得到广泛研究。最近的研究集中在miR - 21的诊断和预后价值及其在人类恶性肿瘤耐药性中的意义。进一步将miR - 21用作癌症治疗的生物标志物和靶点可能会改善癌症患者的预后。本综述重点介绍了与miR - 21在血液系统和非血液系统恶性肿瘤中的重要性相关的最新研究结果。
