Puromycin aminonucleoside, 3'-Amino-3'-deoxy-N6,N6-dimethyladenosine, is the aminonucleoside portion of the antibiotic puromycin. Puromycin aminonucleoside (PAN)-induced nephrosis in rats can provide a model for investigating the pathogenesis of severe proteinuric conditions.

In vitro: A pervious study used scanning (SEM) and transmission (TEM) electron microscopy to test the in vitro effects of PAN on rat glomerular podocytes. Slices of rat kidney were incubated with PAN. SEM analysis of glomeruli on kidney slices indicated incubation with PAN decreased the number of microvilli on podocyte cell bodies and increased the number of glomeruli. TEM morphometry showed PAN incubation significantly retarded the loss of podocyte foot processes that was observed in control groups [1].

In vivo: In Wistar rats, multiple injections of PAN resulted in sustained severe proteinuria and FSGHS lesions of their glomeruli. In PVG/c rats, a higher PAN dose was needed to induce chronic proteinuria. In acute PAN nephrosis induced by a single intravenous injection of PAN the mesangium of Wistar rats showed large amounts of lipid in contrast to a few small mesangial lipid droplets in nephrotic PVG/c rats. Moreover, after injection of colloidal carbon in nephrotic PVG/c rats no enhanced carbon accumulation was found in the mesangium when compared to nonproteinuric controls [2].
