TCF21 and idiopathic membranous glomerulonephritis: To compare histological TCF21 expression in podocytes among NGD and glomerular diseases, their groups were statistically significant among each glomerular disease (Fig. 1g, p < 0.01, based on urinary protein; 0.4 ± 0.4 g/gCre in NGD, 1.1 ± 0.7 g/gCre in IgAN, 5.5 ± 1.4 g/gCre in FSGS, 5.7 ± 1.9 g/gCre in MCD and 6.0 ± 4.7 g/gCre in MGN).
