The top hub genes included ELANE, APP, MMP9, BMP4, MPO, THBS1, VWF, OLFM4, LCN2, and HOXA7, which significantly enriched in regulation of leukocyte migration, myeloid cell differentiation, extrinsic apoptotic signaling pathway, and monocyte differentiation, associated with cancer. This evidence concerns the gene HOXA7 and cancer.
