VEGFA and IgA glomerulonephritis: The positive area of fibrosis as measured by HHF35 significantly correlated with the expression of log10 mRNA of TGF-β1, VEGF-A, and CTGF respectively, for podocytopathies (rs = 0.706, p<0.001; rs = 0.823, p<0.001; and rs = 0.650, p<0.001), proliferative nephritis (rs = 0.719, p = 0.004; rs = 0.868, p<0.001; and rs = 0.767, p = 0.001), and IgA nephropathy (rs = 0.841, p = 0.001; rs = 0.802, p = 0.002; and rs = 0.666, p = 0.018).
