IER2 and neoplasm: Reverse specificity analyses of the expression of each gene associated with tumor‐infiltrating CD8+ T cell content, which can indicate a predilection for immune escape, identified 7 of these 18 genes (PMVK, ATP6V1F, IER2, MRPL51, PSMB6, SF3B5 and TRIR), with PMVK being the only gene that was negatively correlated with tumor‐infiltrating CD8+ T cell content (Figure 1F, Extended Data Figure 1C and Table S1, Supporting Information) and thus deserving of further investigation.
