In addition, we noticed that chronic ETA receptor activation increased the excretion of nephrin into the urine, again suggesting that ETA receptors influence podocyte function and Palb.
Morphologically, others have shown that up-regulation of ET-1 production by podocytes is induced by protein overload, resulting in cytoskeletal changes associated with foot-process effacement, a hallmark of chronic glomerular disease (Morigi et al., 2005). Moreover,it has been reported that inhibition of Rho kinases in podocytes, which are important for the formation of stress fibers, resulted in a significant inhibition of F-actin rearrangement in response to ET-1(Morigi et al., 2006).
