As listed in Figure 8, low expression of FABP4 in tumor tissues (p < 0.05) was validated in five datasets, the lower expression of PLXNB3, INHBB and NKAIN4 in tumor tissues was verified in three datasets (p < 0.05), and the decreased expression of HOXC9 and was validated in one dataset, respectively (p < 0.05). This evidence concerns the gene PLXNB3 and neoplasm.
