The Wilcoxon rank-sum test indicated the expression levels of 4 DEGs among normal and tumor tissue in paired or unpaired samples, which indicated HS3ST3A1 and CAPN8 expressed significantly higher in tumor tissues, while the other two genes, LRRN4CL and PCOLCE2, were not (Figures 6(a) and 6(b)). Here, LRRN4CL is linked to neoplasm.
