Y-box protein 1 mediates PDGF-B effects in mesangioproliferative glomerular disease.

The pivotal role of PDGF-B for mesangioproliferative glomerular disease is well established. Here, Y-box protein-1 (YB-1) was identified as a downstream signaling target of PDGF-B. In healthy kidney cells, YB-1 was located predominantly within the nuclear compartment.
