FBW7 (F-box and WD repeat domain-containing 7) has been characterized as an onco-suppressor protein in human cancers. Recent studies have also shown that FBW7 exerts its anti-tumor function primarily by promoting the degradation of various oncoproteins, through which FBW7 regulates cellular proliferation, differentiation and causes genetic instability. In this review, we will discuss the role of FBW7 downstream substrates and how dysregulation of Fbw7-mediated proteolysis of these substrates contributes to tumorigenesis. Additionally, we will also summarize the currently available various Fbw7-knockout mouse models that support Fbw7 as a tumor suppressor gene in the development and progression of human malignancies.
FBW7(F-box 和 WD 重复结构域包含 7)已被确定为人类癌症中的一种肿瘤抑制蛋白。最近的研究还表明,FBW7 主要通过促进各种癌蛋白的降解来发挥其抗肿瘤功能,通过这种方式,FBW7 调节细胞增殖、分化并导致遗传不稳定性。在这篇综述中,我们将讨论 FBW7 下游底物的作用,以及这些底物的 Fbw7 介导的蛋白水解失调如何促进肿瘤发生。此外,我们还将总结目前可用的各种 Fbw7 基因敲除小鼠模型,这些模型支持 Fbw7 作为人类恶性肿瘤发生和发展中的肿瘤抑制基因。
