cGAS–STING signaling pathway in gastrointestinal inflammatory disease and cancers.

Cyclic GMP‐AMP synthase (cGAS)–stimulator of interferon genes (STING) signaling pathway has emerged as a key DNA‐sensing machinery in innate immunity. Activation of cGAS–STING signaling pathway mediates the production of interferons and proinflammatory cytokines. Although cGAS–STING signaling pathway shows critical function in the maintenance of gut homeostasis, overactive cGAS–STING signaling pathway leads to gastrointestinal (GI) inflammation. Harnessing the effect and mechanism of the cGAS–STING signaling pathway could be beneficial for the development of novel strategies for the treatment of GI diseases. This review presents recent advances regarding the role of cGAS–STING signaling pathway in GI inflammatory disease and cancers and describes perspective therapeutic strategies targeting the signaling pathway.
