Question: Is it possible to classify nephrotic syndrome (NS) through gene expression profiling of podocytes exposed to NS plasma?
Finding: Our data showed different expression profiles in podocytes exposed to nephrotic plasma from different clinical groups, suggesting the molecular stratification of patients into intrinsic subtypes.
Meaning: Transcriptome profiling of podocytes treated with NS plasma can stratify patients into intrinsic subtypes and provide insight into the molecular mechanisms of podocyte injury.
Puromycin aminonucleoside modulates p130Cas of podocytes

Purpose

Puromycin aminonucleoside (PAN) specifically injures podocytes, leading to foot process effacement, actin cytoskeleton disorganization, and abnormal distribution of slit diaphragm proteins. p130Cas is a docking protein connecting F-actin fibers to the glomerular basement membrane (GBM) and adapter proteins in glomerular epithelial cells (GEpCs; podocytes). We investigated the changes in the p130Cas expression level in the PAN-induced pathological changes of podocytes...
