Ribosomal biogenesis is tightly associated with cellular activities, such as growth, proliferation, and cell cycle progression. Perturbations in ribosomal biogenesis can initiate so-called nucleolar stress. The process through which ribosomal proteins (RPs) transduce nucleolar stress signals via MDM2 to p53 has been described as a crucial tumor-suppression mechanism. In this review we focus on recent progress pertaining to the function and mechanism of RPs in association with the MDM2-p53 tumor-suppression network, and the potential implications this surveillance network has for cancer development.
核糖体生物合成与细胞活动紧密相关,如生长、增殖和细胞周期进程。核糖体生物合成的扰动可引发所谓的核仁应激。核糖体蛋白(RPs)通过MDM2将核仁应激信号转导至p53的过程已被描述为一种关键的肿瘤抑制机制。在本综述中,我们聚焦于核糖体蛋白在与MDM2-p53肿瘤抑制网络相关的功能和机制方面的最新进展,以及这个监测网络对癌症发展的潜在影响。
