YTHDC2 expression was significantly positively correlated with the infiltration levels of B Cell, CD8+ T cell, CD4+ T cell, macrophage, Neutrophil, and Dendritic Cell in BRCA‐Basal, COAD, KIRC, and LUAD; with the infiltration levels of CD8+ T cell, CD4+ T cell, macrophage, neutrophil and dendritic cell in HNSC‐HPVneg; with the infiltration levels of B cell, CD8+ T cell, neutrophil and dendritic cell in READ; with the infiltration levels of CD8+ T cell, neutrophil and dendritic cell in OV (Figure S5). Here, CD4 is linked to reading.
