Indeed, we found that inhibition of ATM led to a robust increase in the expression of cGAS, the phosphorylation of STING and TBK1 in a variety of human cancer cell lines, including HeLa, H157, H1299, A549, MDA-MB-231 and BT549 (Fig. 3A, Fig. S3A and B). This evidence concerns the gene STING1 and cancer.
