摘要
三基色修复外切酶 1(TREX1)与多种以慢性和先天性炎症为特征的病症有关。有人认为,通过 cGAS-STING 通路进行 DNA 检测而导致的先天性免疫失调在这些干扰素病的病因中扮演了重要角色。然而,人们对这种DNA感应的分子来源以及TREX1可能参与基因组(不)稳定的情况仍然知之甚少。最近的发现再次引发了关于 TREX1 核酸酶的细胞功能的争论,特别是在染色体生物学和稳定性方面。最近的研究结果表明,在不同的病理情况下,TREX1处于DNA损伤反应和炎症的交叉路口。
T-Rex escaped from the cytosolic park: Re-thinking the impact of TREX1 exonuclease deficiencies on genomic stability
The Three Prime Repair Exonuclease 1 (TREX1) has been implicated in several pathologies characterized by chronic and inborn inflammation. Aberrant innate immunity caused by DNA sensing through the cGAS-STING pathway has been proposed to play a major role in the etiology of these interferonopathies. However, the molecular source of this DNA sensing and the possible involvement of TREX1 in genome (in)stability remains poorly understood. Recent findings reignite the debate about the cellular functions performed by TREX1 nuclease, notably in chromosome biology and stability. Here I put into perspective recent findings that suggest that TREX1 is at the crossroads of DNA damage response and inflammation in different pathological contexts.
期刊介绍:
molecular – cellular – biomedical – physiology – translational research – systems - hypotheses encouraged
BioEssays is a peer-reviewed, review-and-discussion journal. Our aims are to publish novel insights, forward-looking reviews and commentaries in contemporary biology with a molecular, genetic, cellular, or physiological dimension, and serve as a discussion forum for new ideas in these areas. An additional goal is to encourage transdisciplinarity and integrative biology in the context of organismal studies, systems approaches, through to ecosystems, where appropriate.
