Abstract: |
Cytosolic DNA is prevalent in cells constituting the tumor microenvironment (TME) and can activate the cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon genes (STING) innate immune pathway. The initiation, transmission, and execution of the cGAS-STING pathway can take place among different cell types within the TME and thus cGAS-STING may play opposing roles in driving tumor progression in addition to its tumor cell-intrinsic role. Herein, we review recent advances in the cGAS-STING field with a focus on its crosstalk with other signaling pathways in the TME. Future efforts to depict a more detailed picture of the roles of cGAS-STING signaling in the TME will help design a better cancer treatment regime by targeting the cGAS-STING pathway more precisely. © The Author(s) (2022).
