WebApr 12, 2024 · The authors demonstrate how the combination of CIN, TMB, and cGAS-STING activation tumor suppression of infiltrating immune cells may represent a discrete mechanism of immune evasion. The authors specifically investigate the interaction between the cGASSTING pathway, tumor inflammation, CIN, TMB, and response to immunotherapy. WebTumors with high levels of CIN face a unique challenge in which their chronic release of cytosolic DNA poses a risk to activate cGAS-STING mediated IFN signaling. To …

CIN can also …
WebIn fact, genomic datasets from cancerous tissues and cell lines, combined with analysis of an experimental model of tumor aneuploidy, support a CIN model of tumor evolution, where initial induction of CIN activates cGAS/STING and proinflammatory signaling pathways, leading to a proimmunogenic state in the tumor (Figures 5 and 6). However, as ... WebCIN induction also increased levels of the cytokine IL-6, depen-dent on the presence of cGAS and STING. IL-6 is a known activator of STAT3, and IL-6 supplementation rescued the viability of cGAS- or STING-knockout TNBC cells undergoing CIN. Therefore, cancer cells with CIN seemed to rely on a cGAS-mediated IL-6–STAT3
WebChromosomal instability (CIN) in cancer cells has been reported to activate the cGAS-STING innate immunity pathway via micronuclei formation, thus affecting tumor immunity and tumor progression. However, adverse effects of the cGAS/STING pathway as they relate to CIN have not yet been investigated. … WebAug 9, 2024 · The cyclic GMP-AMP (cGAMP) synthase (cGAS) has been identified as a cytosolic double stranded DNA sensor that plays a pivotal role in the type I interferon and inflammation responses via the STING-dependent signaling pathway. In the past several years, a growing body of evidence has revealed that cGAS is also localized in the …
