摘 要:摘 要:miRNA-125 家族是由在进化上高度保守的miRNA-125a-3p、miRNA-125a-5p、 miRNA125b-1、miRNA-125b-2 组成,其表达紊乱与肿瘤的发生与发展密切相关。miRNA-125 家族的下游靶点包括转录因子如STAT3、细胞因子( 如IL-6, TGF-β)、相关蛋白( 如抑癌蛋白p53、促凋亡蛋白Bak1、RNA 结合蛋白HuR) 等。miR-125 家族参与调控这些靶点进而影响肿瘤的发生发展。现主要总结了miRNA-125 家族及其靶基因在抑制与促进肿瘤发生、发展方面的双重作用,并从增殖、凋亡、侵袭与转移和免疫反应等4 个方面详细阐述了其作用机制。

Abstract: Abstract: miRNA-125 family, a highly conserved miRNA family throughout evolution, consists of miRNA-125a-3p, miRNA-125a-5p, miRNA-125b-1 and miRNA-125b-2. The aberrant expression of miRNA-125 family is tightly related to tumorigenesis and tumor development. The downstream targets of miRNA-125 include transcription factors like STAT3, cytokines like IL-6 and TGF-β, tumor suppressing protein p53, pro-apoptotic protein Bak1 and RNA binding protein HuR, etc. In this review, we mainly summarize the dual functions of miRNA-125 family in suppression and promotion of cancer cells and further elaborate its regulatory mechanisms from four facets: proliferation, apoptosis, invasion and metastasis, and immune response.
