STING1 and neoplasm: Moreover, investigating CellMiner Cross Database (CellMinerCDB) data [42], we observed that STING expression in lung cancer cell lines is positively correlated (Pval = 4.6e-16) with antigen-presenting machinery score (Supplementary Fig. S12C), a prediction index for tumour response to immune checkpoint inhibitors [43], while negatively correlates (Pval = 5.4e-30) with STING gene methylation (Supplementary Fig. S12D), consistently with observation in TCGA LUAD and LUSC samples.
