摘要:

LIN28A及其同源蛋白LIN28B是高度保守的RNA结合蛋白,在胚胎早期发育、体细胞重编程、葡萄糖代谢以及肿瘤发生发展中具有重要作用。LIN28A/B在乳腺癌等恶性肿瘤中高表达,在肿瘤的起始、维持和转移中均发挥重要作用,并与预后不良相关。研究表明,LIN28A/B主要通过抑制let-7s等microRNA和直接靶向mRNA的方式发挥调控作用。本文主要综述了LIN28A/B在肝癌、乳腺癌、结直肠癌等恶性肿瘤中的功能及其分子调控机制,以期为进一步研究LIN28A/B的作用机制及其在临床治疗中的可能应用提供理论参考。

Abstract:

LIN28A and its homolog LIN28B are highly conserved RNA-binding proteins that play important roles in early embryonic development, somatic cell reprogramming, metabolism and tumorigenesis. LIN28A/B are highly expressed in a variety of malignant tumors such as breast cancer. They play important roles in the initiation, maintenance, and metastasis of tumors and are associated with poor prognosis. Previous studies have shown that the main regulatory mechanisms of LIN28A/B include let-7s dependent ways and let-7s independent ways, such as directly targeting mRNA. In this review, we summarize the function and molecular regulatory mechanisms of LIN28A/B in malignant tumors such as liver cancer, breast cancer and colorectal cancer, in order to provide references for further exploring the function and mechanism of LIN28A/B and their possible roles in clinical applications.

Key words: LIN28A, LIN28B, let-7 miRNA, tumor development and progression, therapeutic targets
