U-sed pod mRNA and u-sup PCX was different excretion pattern in glomerular diseases. (A) Proteinuria in glomerular diseases. (B) u-sed Pod mRNA excretion in glomerular diseases. (C) u-sup PCX protein in glomerular diseases. Proteinuria was significantly increased in all of the glomerular diseases. u-sed Pod mRNA excretion was also significantly increased in all of the glomerular diseases compared with controls, and further increased in IgA nephropathy (IgAN), crescentic GN (CreGN), and lupus nephritis (LN); however, u-sup PCX protein was significantly increased only in those with membranous nephropathy (MN) and LN compared with the controls. *P<0.05, **P<0.01 versus controls, assessed by Kruskal–Wallis test followed by Dunn test. Cr, creatinine; MCNS, minimal change nephrotic syndrome; minor, minor glomerular abnormality with mild proteinuria and/or microscopic hematuria.
