摘要:

胰岛素样生长因子2 mRNA结合蛋白3(IGF2BP3)是生物体中重要的RNA结合蛋白,在调控mRNA定位、稳定性和转录后翻译等过程中均发挥关键作用。N6-甲基腺嘌呤(m6A)是哺乳动物mRNA上最为普遍的修饰之一,IGF2BP3可作为m6A甲基化修饰的阅读蛋白参与调控mRNA代谢。IGF2BP3在多种恶性肿瘤中呈高表达并与患者不良预后相关, 靶向IGF2BP3或其上下游调控网络可能成为肿瘤治疗新策略。本文总结了IGF2BP3作为RNA结合蛋白和m6A阅读蛋白,在胶质母细胞瘤(GBM)、乳腺癌(BC)和肺癌等多种肿瘤细胞中调控细胞增殖、侵袭、代谢重编程及耐药性等恶性生物学行为的作用及其可能的机制,以期为恶性肿瘤治疗提供新思路。

Abstract:

Insulin-like growth factor 2 mRNA binding protein 3 (IGF2BP3) is a critical RNA-binding protein in organisms, playing key roles in the regulation of mRNA localization, stability, and post-transcriptional translation. N6-methyladenosine (m6A) is one of the most prevalent modifications on mammalian mRNA, and IGF2BP3 may function as a reader protein for m6A methylation modifications involved in regulating mRNA metabolism. IGF2BP3 is highly expressed in various malignant tumors and is associated with poor prognosis in the patients. Targeting IGF2BP3 or its upstream and downstream regulatory networks may represent a novel strategy for cancer therapy. This review summarized the roles and potential mechanisms of IGF2BP3, acting as both a RNA-binding protein and an m6A reader protein, in regulating malignant biological behaviors including proliferation, invasion, metabolic reprogramming, and drug resistance in various tumor cells such as glioblastoma(BGM), breast cancer(BC), and lung cancer, in order to provide novel insights for the treatment of malignant tumors.

Key words: IGF2BP3, m6A modification, Malignant tumor, Methylation, Therapeutic target, Tumor progression
