The expression of the 20 genes in the disease and normal groups is shown in Figure 5B, in which ARTN, BMP7, CXCL14, LTB4R, GAL, ACKR3, WNT5A, NTS, GAST, NPPC, and POMC were significantly up-regulated in tumor tissues as compared to normal tissues. This evidence concerns the gene LTB4R and neoplasm.
