When comparing the expression of our hub genes in DKD samples against this compendium, we identified that studies that comprise the following immune cell samples, dendritic, Calu3, CD4T, CD16/CD14 monocytes, NK and A549lowMOI cells, are the ones that overlapped in the expression—ISG15 being the most conserved differentially expressed gene (8), followed by STAT1 (7), OAS1 (6) and IRF2 (2) (Figure 9a). Here, ISG15 is linked to diabetic kidney disease.
