Proteinuria promotes chronic kidney disease progression. Karoui et al. show that proteinuria stimulates overexpression of iron transporting protein lipocalin-2 via Ca2+release-induced ER stress, which leads to tubular apoptosis, and that inhibition of this pathway by PBA delays renal deterioration in proteinuric mice.
