MicroRNA-34 (miR-34) 是肿瘤抑制的主要调节因子。它在多种癌症中下调,并通过抑制参与各种致癌信号通路的基因来抑制恶性生长。因此,miR-34 拮抗基本癌细胞活力以及癌症干性、转移和化疗耐药性所必需的过程。这种广泛的抗癌活性有望创造出一种有效对抗肿瘤异质性的新疗法。本综述重点关注 miR-34 介导的肿瘤抑制的分子机制、癌症动物模型中的药理学,以及 miR-34 疗法的状态更新,该疗法可能是首批进入临床的 miRNA 模拟物之一。
MicroRNA-34 (miR-34) is a master regulator of tumor suppression. It is downregulated in numerous cancers and inhibits malignant growth by repressing genes involved in various oncogenic signaling pathways. Consequently, miR-34 antagonizes processes that are necessary for basic cancer cell viability as well as cancer stemness, metastasis, and chemoresistance. This broad anti-oncogenic activity holds the prospect of creating a new remedy that is effective against tumor heterogeneity. This review focuses on the molecular mechanisms of miR-34-mediated tumor suppression, pharmacologies in animal models of cancer, and a status update of a miR-34 therapy that may be among the first miRNA mimics to reach the clinic.
