Fig. 4From: Alteration of histone H3K4 methylation in glomerular podocytes associated with proteinuria in patients with membranous nephropathyLocalization of histone H3K4 me3 in mouse kidney glomeruli. Immunohistochemical staining indicates the co-localization of trimethyl-histone H3K4 (H3K4 me3) with the podocyte marker WT-1. The overlapping staining for WT-1 (red, a) and H3K4 me3 (green, b) results in the merged image (yellowish, c) as indicated by the arrowBack to article page
