Hence, our study aims to investigate protective effect of hUSC exosome along with microRNA-16-5p (miR-16-5p) on podocytes in DN via vascular endothelial growth factor A (VEGFA).
Thus, this study was conducted to explore the effect of CaD on restoring autophagy in DKD and the possible signaling pathway between VEGF and autophagy.
We hypothesized that glomerular LRG1 expression is increased earlier than VEGF expression under conditions of pathological angiogenesis in the early stage of diabetic nephropathy.
In the present study, we investigated the effect of Pueraria tuberosa extract (PTY-2r) on the expression of HIF-1α, VEGF and nephrin in streptozotocin (STZ) induced diabetic nephropathy (DN).
Unlike its experimental counterpart, human diabetic nephropathy is associated with diminished VEGF-A levels and experience in the oncological setting has taught us that VEGF blocking therapy can cause adverse renal effects in patients.
We assessed MBL levels and corresponding MBL2 genotype, together with vascular endothelial growth factor (VEGF) levels as a marker of vascular damage, in type 1 diabetes patients with diabetic nephropathy before and after simultaneous pancreas-kidney (SPK) transplantation.
The pattern of renal VEGF-A splice variants was unchanged in diabetic nephropathy and lupus nephritis and was stable throughout disease progression in acute transplant rejection and diabetic nephropathy; these results suggest renal VEGF-A splicing stability during kidney disease.
Most of these eleven genetic variants were involved in GPCR signaling and receptor binding pathways whereas four were involved in chronic kidney failure. rs833061 [OR 2.08 (95% CI 1.63-2.66)] in the VEGFA gene and rs3917887 [OR 2.04 (95% CI 1.64-2.54)] in the CCL2 gene showed the most significant association with the risk of diabetic nephropathy.
Considering the putative contribution of VEGF to T2D and its complications, we aimed to assess the effect of these VEGF-related SNPs on the risk of T2D, nephropathy and retinopathy, as well as on variation in related traits.SNPs were genotyped in several case-control studies: French and Danish T2D studies (N(cases) = 6,920-N(controls) = 3,875 and N(cases) = 3,561-N(controls) = 2,623; respectively), two French studies one for diabetic nephropathy (N(cases) = 1,242-N(controls) = 860) and the other for diabetic retinopathy (N(cases) = 1,336-N(controls) = 1,231).
Immunohistochemistry showed both increased TRPC6 channel protein and VEGF receptor type 2 (VEGFR-2) protein in podocytes from patients with diabetic nephropathy compared to control subjects.
Pathway analysis highlighted the regulation of Ras homolog gene family member A, Cdc42, integrin, integrin-linked kinase, and vascular endothelial growth factor signaling in DKD glomeruli.
Soluble Flt-1 (sFlt-1) is the endogenous inhibitor of VEGF, and recently genetic overexpression of sFlt-1 in the podocyte was shown to be protective in murine diabetic nephropathy.
In diabetes, over-production of NO might play a role in the development of diabetic nephropathy, while reduced NO production may be related to the development of diabetic retinopathy and neuropathy, where VEGF (vascular endothelial growth factor) levels are increased in a counter regulatory manner.
Vascular endothelial growth factor (VEGF) is a dimeric glycoprotein that plays a crucial role in microvascular complications of diabetes, including diabetic nephropathy.
HG also augmented VEGF expression, decreasing nephrin expression and podocyte number-a critical event for the development of proteinuria in diabetic nephropathy.
There was no difference in VEGF genotype distribution between the control and diabetic patients based on the state of diabetic nephropathy and neuropathy.
Podocyte-derived vascular endothelial growth factor (VEGF), a permeability and angiogenic factor whose expression is also increased in animal models of diabetic kidney disease, appears to act in a novel autocrine signaling mode to induce the podocytopathy of diabetes, especially the genesis of albuminuria.
