Abstract

Glomerular issues and affected podocytes are at the origin of 80% of chronic kidney disease cases. Thus, acquiring a deeper understanding in this domain is necessary to halt progressive kidney damage. In this study, the authors investigated the harmful impact of podocyte-cleaved soluble retinoic acid receptor responder protein-1 on podocytes and proximal tubular cells and identified matrix metalloprotease 23 as the enzyme responsible for cleaving retinoic acid receptor responder protein-1. These findings provide new insights into chronic kidney disease progression, suggesting innovative treatment avenues.
