Abstract:
The activation of innate immune response after the engagement of dsDNA is an evolutionarily preserved sophisticated strategy against invading microbial pathogens. cGAS has been identified as one of the major dsDNA sensor present in the cytoplasm which catalyzes the synthesis of a cyclic dinucleotide 2'3'cGAMP, as the secondary messenger that binds and activates the downstream stimulator of interferon (IFN) genes (STING) for subsequent production of type 1 IFNs and other inflammatory genes. Recent progress in the mechanical understanding of cGAS/STING signalling has unveiled its intricate role in tumor progression and metastasis. In this review, we specifically focus on new developments concerning the role of cGAS/STING signalling in regulating antitumorigenesis and tumorigenesis.
