Our study, however, was unable to confirm these findings in MCD, and instead found increased expression of Angptl4 in 2 MCD patients during remission, in 5 of 6 patients with active FSGS, in 1 case of MPGN in relapse, and 1 subject with class IV lupus nephritis during relapse and in 1 MPGN patient with mild proteinuria (Fig 3). Here, ANGPTL4 is linked to focal segmental glomerulosclerosis.
