In seven diabetic patients with proliferative retinopathy, the most profound finding was a significant decrease of the PEDF level (mean value: 237 ng/ml), whereas VEGF levels were comparable to diabetic patients without proliferation (mean value: 3153; p = 0.003).

Earlier studies showed that the level of PEDF was decreased and VEGF was increased in proliferative diabetic retinopathy in human eyes.

Intravitreal injection of PEDF significantly reduced vascular hyper-permeability in rat models of diabetes and oxygen-induced retinopathy, correlating with the decreased levels of retinal inflammatory factors, including VEGF, VEGF receptor-2, MCP-1, TNF-alpha, and ICAM-1.

Moreover, down-regulation of PEDF expression by siRNA resulted in significantly increases of VEGF and TNF-alpha secretion in retinal Müller cells.

To investigate the effect of PEDF and vascular endothelial growth factor (VEGF) on leukostasis, the adhesion of monocytes to human umbilical vein endothelial cells (HUVECs) was assayed in vitro.

|
In vitro studies showed that exposure of HUVECs to VEGF increased the number of adhering monocytes, and PEDF inhibited the VEGF-induced leukostasis in a dose-dependent manner.

In cultured primary human renal mesangial cells (HMC), the high-glucose medium-induced upregulation of VEGF and MCP-1 was largely blocked by PEDF.

The decreased levels of blood VEGF after an intravitreal injection of bevacizumab indicate that bevacizumab enters the general circulation and may also affect the PEDF levels.

Retinal transfection with the hPEDF gene construct led to sustained hPEDF gene expression for 6 months, significantly suppressing VEGF mRNA expression in the retina after 1, 3, and 6 months of diabetes induced by STZ compared with paired controls.

We found a dose-dependent increase in cell survival with VEGF or Epo, which was attenuated in the presence of PEDF.

|
In addition, PEDF significantly (P < 0.05) inhibited migration and in vitro tube formation in RECs in the presence of VEGF as like PI3K/Akt inhibitor.

|
Of interest, PEDF effectively abrogated VEGF-mediated phosphorylation of PI3K/Akt.

|
Further studies using RECs transfected with constitutively active and dominant-negative forms of Akt suggest that PEDF could inhibit VEGF- and also Epo-induced angiogenesis by disruption of PI3K/Akt signaling.
