CD2AP-deficient mice develop nephrotic syndrome and renal failure caused by glomerulosclerosis. Here we report that increased transforming growth factor-beta1 (TGF-beta1) expression and apoptosis were present in podocytes at the onset of albuminuria and were followed by depletion of podocytes associated with progressive focal-segmental glomerulosclerosis in CD2AP-/- mice. Conditionally immortalized podocytes derived from CD2AP-/- mice were more susceptible to TGF-beta-induced apoptosis compared with CD2AP+/+ podocytes. Reconstitution of CD2AP rescued CD2AP-/- podocytes from TGF-beta-induced apoptosis. CD2AP was required for early activation of anti-apoptotic phosphatidylinositol 3-kinase (PI3K)/AKT and extracellular signal-regulated kinase 1/2 by TGF-beta. In contrast, activation of pro-apoptotic p38 MAPK by TGF-beta was accelerated and enhanced in the absence of CD2AP. CD2AP was not required for PI3K/AKT activation by insulin and epidermal growth factor, indicating that CD2AP is a selective mediator of anti-apoptotic TGF-beta signaling. In summary, we identified CD2AP as a novel mediator for selective activation of survival pathways and repression of apoptosis signaling by TGF-beta in podocytes. Together, our in vitro and in vivo findings suggest that TGF-beta-induced podocyte apoptosis is an early pathomechanism in mice developing focal-segmental glomerulosclerosis associated with functional impairment of CD2AP." ?g. }
