To assess the pathogenic role of AGEs and vascular endothelial growth factor (VEGF) in the development of retinal neovascularization in diabetic retinopathy, we investigated the effect of AGEs on induction of VEGF by retinal Muller cells and measured AGE and VEGF concentrations in the vitreous of patients with proliferative diabetic retinopathy (PDR) and nondiabetic patients.
We examined 20 epiretinal membranes from patients with proliferative diabetic retinopathy (PDR) (n = 12) and proliferative vitreoretinopathy (PVR) (n = 8) for the presence of bFGF peptide, fibroblast growth factor receptor-1 (FGFR-1) and bFGF messenger ribonucleic acid (mRNA).
We investigated whether the polymorphism of the beta 3-adrenoreceptor (beta 3-AR) gene, which is associated with insulin resistance and an earlier onset of NIDDM, was associated with proliferative diabetic retinopathy (PDR) in 215 Japanese NIDDM patients with a duration of diabetes of > or = 10 years.
We examined 20 epiretinal membranes from patients with proliferative diabetic retinopathy (PDR) (n = 12) and proliferative vitreoretinopathy (PVR) (n = 8) for the presence of bFGF peptide, fibroblast growth factor receptor-1 (FGFR-1) and bFGF messenger ribonucleic acid (mRNA).
To evaluate the relationship between the ACE insertion/deletion polymorphism and proliferative diabetic retinopathy in patients with type 1 diabetes of long duration.
Lack of association between the heparan sulfate proteoglycan gene polymorphism and diabetic nephropathy in Japanese NIDDM with proliferative diabetic retinopathy.
We investigated the relationship between advanced diabetic retinopathy (ADR) and an angiotensin-converting enzyme (ACE) gene polymorphism in subjects with type 2 diabetes and ADR, pre-proliferative (PrePDR) or proliferative diabetic retinopathy (PDR) without overt nephropathy.
Adrenomedullin mRNA levels in the tissues obtained from patients with intraocular or orbital tumors were significantly higher than those of patients with proliferative vitreoretinopathy (P <.05), proliferative diabetic retinopathy (P <.05), preretinal macular fibrosis (P <.005), and acute retinal necrosis (P <.01).
To detect the expression of mRNA of protooncogenes ets-1, c-jun, c-fos, and platelet-derived growth factor (PDGF) in proliferative membranes of patients with proliferative diabetic retinopathy (PDR) and proliferative vitreoretinopathy (PVR).
The object of the study was to investigate the share of the polymorphisms I/D ACE, endothelin 1 4127G/A and TNF-beta NcoI in the susceptibility to proliferative diabetic retinopathy (PDR) in non-insulin-dependent diabetes mellitus (NIDDM).
The object of the study was to investigate the share of the polymorphisms I/D ACE, endothelin 14127G/A and TNF-beta NcoI in the susceptibility to proliferative diabetic retinopathy (PDR) in non-insulin-dependent diabetes mellitus (NIDDM).
Polymorphism R25P in the gene encoding transforming growth factor-beta (TGF-beta1) is a newly identified risk factor for proliferative diabetic retinopathy.
To determine if the renin-angiotensin system (RAS) is involved in diabetic retinopathy, we measured the levels of angiotensin-converting enzyme (ACE) and angiotensin II in the vitreous of patients with proliferative diabetic retinopathy (PDR).
Neither the 4G/5G PAI-1 gene polymorphism nor the I/D ACE gene polymorphism contributed to the genetic susceptibility to diabetic retinopathy, either non-proliferative, proliferative or severe proliferative diabetic retinopathy, i.e. visual acuity of 0.1 or less in the better eye, in a group of Caucasian subjects with type 2 diabetes.
Increased levels of von Willebrand factor, reflecting activation or damage of endothelial cells, have been described in association with proliferative diabetic retinopathy (PDR).
Three novel polymorphisms in the promoter region of the TIMP-3 gene are not associated with proliferative diabetic retinopathy in type 2 diabetes mellitus.
