Angptl4 expression was upregulated in patients with MCD compared to those with mesangial proliferative glomerulonephritis, and urinary Angptl4 excretion was higher in MCD, MN, and FSGS patients compared to those with MsPGN, however no differences were observed in patients with MCD vs. FSGS or MN (63). Here, ANGPTL4 is linked to focal segmental glomerulosclerosis.
