The cytosolic DNA-sensing cGAS-STING pathway was originally characterized as a key innate immune mediator responsible for the induction of antiviral genes in response to foreign DNA species in the cytosol. Mounting evidence, however, points to a complex role for cGAS and STING in cancer. Two recent reports, by Ranoa et al. (Cancer Research, 2018;https://doi.org/10.1158/0008-5472.CAN-18-1972) and Nassour et al. (Nature 2019;565:659-663), dissect the function of this pathway during the early steps of cellular transformation and shed light on the complexity and context-dependence of cGAS-STING signaling in cancer.
胞质DNA感应cGAS-STING通路最初被认为是一种关键的固有免疫介质,负责在细胞质中感应外来DNA种类时诱导抗病毒基因。然而,越来越多的证据表明cGAS和STING在癌症中发挥着复杂的作用。Ranoa等人(《癌症研究》,2018年;https://doi.org/10.1158/0008-5472.CAN-18-1972)和Nassour等人(《自然》,2019年;565:659-663)最近的两项报告剖析了该通路在细胞转化早期阶段的功能,并揭示了癌症中cGAS-STING信号传导的复杂性和背景依赖性。
