ANGPTL4 and glomerular disorder: To further elucidate the relationship between the expression levels of ANGPTL4 and the duration from disease onset (edema) to renal biopsy and to confirm the widespread expression of ANGPTL4 in podocytes in glomerular diseases with different renal pathologies, we included a cohort of 31 individuals from another center, comprising untreated nephrotic syndrome patients with MCD (n = 9), MN (n = 9), and FSGS (n = 4).
