Abstract

When not dividing, many cell types target their centrosome to the plasma membrane, where it nucleates assembly of a primary cilium, an antenna-like signaling structure consisting of nine concentric microtubule pairs surrounded by membrane. Primary cilia play important pathophysiological roles in many tissues, their dysfunction being associated with cancer and ciliopathies, a diverse group of congenital human diseases. Several recent studies have unveiled functional connections between primary cilia and NRF2 (nuclear factor erythroid 2-related factor 2), the master transcription factor orchestrating cytoprotective responses to oxidative and other cellular stresses. These NRF2-cilia relationships are reciprocal: primary cilia, by promoting autophagy, downregulate NRF2 activity. In turn, NRF2 transcriptionally regulates genes involved in ciliogenesis and Hedgehog (Hh) signaling, a cilia-dependent pathway with major roles in embryogenesis, stem cell function and tumorigenesis. Nevertheless, while we found that NRF2 stimulates ciliogenesis and Hh signaling, a more recent study reported that NRF2 negatively affects these processes. Herein, we review the available evidence linking NRF2 to primary cilia, suggest possible explanations to reconcile seemingly contradictory data, and discuss what the emerging interplay between primary cilia and NRF2 may mean for human health and disease.

摘要

在不进行分裂时,许多细胞类型会将其中心体定位到质膜,在那里它会促使初级纤毛的组装,初级纤毛是一种类似天线的信号结构,由九对同心微管组成并被膜包围。初级纤毛在许多组织中发挥着重要的病理生理作用,其功能障碍与癌症和纤毛病相关,纤毛病是一组多样的先天性人类疾病。最近的几项研究揭示了初级纤毛与NRF2(核因子红细胞2相关因子2)之间的功能联系,NRF2是协调细胞对氧化和其他细胞应激的细胞保护反应的主要转录因子。这些NRF2与纤毛的关系是相互的:初级纤毛通过促进自噬来下调NRF2的活性。反过来,NRF2转录调控参与纤毛发生和刺猬(Hh)信号传导的基因,Hh信号传导是一种依赖纤毛的途径,在胚胎发育、干细胞功能和肿瘤发生中起主要作用。然而,虽然我们发现NRF2刺激纤毛发生和Hh信号传导,但最近的一项研究报告称NRF2对这些过程有负面影响。在此,我们综述了将NRF2与初级纤毛联系起来的现有证据,提出了调和看似矛盾的数据的可能解释,并讨论了初级纤毛与NRF2之间新出现的相互作用对人类健康和疾病可能意味着什么。
