As shown in Supplementary Figure 2, FABP5 and MS4A7 demonstrated a significantly higher expression in normal tissue (p < 0.05), while the expression levels of TIMP1, KRT8, and WFDC2 were significantly higher in tumor tissue (p < 0.05); the four remaining genes VCAN, HLA-DPA1, HLA-DQA1, and SFTPB demonstrated no significant differential expression between tumor and normal tissue (p > 0.05). The gene discussed is MS4A7; the disease is neoplasm.
