We therefore investigated whether VEGF signals to reduce apoptosis and the role of nephrin in this survival mechanism.

Although VEGF reduced apoptosis in human conditionally immortalized podocytes [wild-type (WT)] by 18.1% of control (P < 0.001), it was unable to do so in nephrin-deficient human conditionally immortalized podocytes.

Moreover, Western blotting and immunodetection with an anti-nephrin antibody showed that the phosphorylation of nephrin, compared with serum-starved WTs, was significantly increased (ratio of 3.36 +/- 1.2 to control, P < 0.05) by VEGF treatment and significantly reduced by treatment with a neutralizing VEGF monoclonal antibody (mAb) (ratio of 0.2 +/- 0.09 to control, P < 0.05).

We suggest therefore that both exogenous and endogenous (podocyte derived) VEGF can stimulate the phosphorylation of nephrin and through this action may prevent podocyte apoptosis.

Moreover, VEGF blockade induced ET-1 release from endothelial cells, and in turn the conditioned medium obtained triggered nephrin loss.

After second injected with adriamycin,the model group nephrin presented a weak signal in the end of the first week (P < 0.05), and the expression of VEGF started to increase at the end of the eighth week (P < 0.05).

The expression of nephrin and the number of podocyte were negatively correlated with the 24-hour urine protein, blood urea nitrogen and serum creatinine; while the expression of VEGF was positively correlated with the 24-hour urine protein, blood urea nitrogen and serum creatinine.

It also led to increased VEGF receptor 2 and semaphorin3a levels, as well as nephrin and matrix metalloproteinase-2 downregulation, whereas circulating VEGF-A levels were similar to those in control diabetic mice.

Furthermore, PAN-induced up-regulation of desmin, down-regulation of synaptopodin and nephrin, and disruption of glomerular morphology were significantly attenuated in VEGF-induced transgenic mice.

We previously showed that in vivo nephrin associates with VEGF receptor-2 (VEGFR2), the signaling receptor for VEGF-A.
