NQO1 and type 2 diabetes mellitus: Figure 2 portrays 106 negatively and 63 positively coexpressed genes in both patient types, whereby 173 intersectional coexpression genes were screened out. Interestingly, of these intersectional coexpression genes, we found 3 genes (CENPBD1P1, KHDRBS3, and PHOX2B) that were positively coexpressed with NPPB in patients with T2DM, but negatively coexpressed in patients without T2DM, and 1 gene (NQO1) that was negatively coexpressed with NPPB in patients with T2DM, but positively coexpressed in patients without T2DM.
