A search of the Nephromine database of published kidney transcriptome datasets disclosed that OPG mRNA was increased in the tubulointerstitium of a different DN data set (fold-change vs control: 2.4, p = 4.83E-4) as well as in IgA nephropathy (fold-change vs control: 1.7, p = 2.07E-4) [34], [38], [39], [40]. The gene discussed is TNFRSF11B; the disease is liver dysplastic nodule.
