Elevated MYL9 expression was associated with increased DC infiltration in STAD and COAD, and consistent with this, the DC markers including CD1C, CD141, HLA‐DPB1, HLA‐DRA1, BDCA‐4(NRP1), and CD11c(ITGAX) linked with the expression level of MYL9. This evidence concerns the gene MYL9 and colon adenocarcinoma.
