Research progress of cGAS-STING in tumor metastasis / 药学学报

ABSTRACT

Cyclic GMP-AMP synthase (cGAS)-stimulator of interferon gene (STING) signaling pathway as an essential immune response pathway in cytoplasm, can find cytoplasmic DNA to regulate the innate immune and adaptive immune response. Studies have shown that the signaling pathway can be activated by both tumor self-DNA and genomic instability, thus to promote or inhibit the development and metastasis of tumors. Therefore, the role of cGAS-STING in tumor genesis, development and metastasis will be systematically expounded from the structures, physiological functions, inhibitors and agonists of cGAS and STING as well as its pathway transduction regulation in this paper. The paper aims to offer theoretical basis and reference for targeting cGAS-STING anti-tumor drugs in clinical practice and cancer clinical and cancer research workers.
