To confirm the downstream effects of the DDR and STING activation, we further demonstrate that Ara-C/DS is able to increase the surface expression on the cancer cell lines of the T cell ligand MHC I, as well as the NK cell ligands MHC class I chain-related protein A and B [MICA/B], and UL16-binding proteins [ULBP] 2, 5 and 6). This evidence concerns the gene STING1 and cancer.
