In our study, PLD-LD partially reduced the fusion and effacement of the foot process, and increased nephrin and podocin expression, suggesting that podocyte injury is closely associated with the incidence of glomerular sclerosis in our model, and PLD-LD may attenuate the progression of FSGS through protection afforded to podocyte injury. The gene discussed is NPHS1; the disease is focal segmental glomerulosclerosis.
