CXCL9 and neoplasm: There were 12 differentially expressed mRNAs between cancer and adjacent samples, among which ANXA6, CCL21, MEIS1, NRXN3, NXPH3, PDZRN3, PLA2G2A, PRELP, SLITRK3, and SOD3 showed lower expression in tumor samples, and BCL2L14 and CXCL9 were highly expressed in cancer samples (Figure 4(a)).
