diabetic retinopathy/proline

OBJECTIVE Neuropeptide Y is a potent vasoconstrictor thought to enhance the development of atherosclerosis. The leucine 7 to proline 7 (Leu7Pro) polymorphism, located in the signal peptide part of the human preproneuropeptide Y, has been associated with serum lipid levels, intima-media thickness of

OBJECTIVE To observe the expression of proline hydroxylase domain 2 (PHD2) in the retina of diabetic rats and investigate the relationship between PHD2 and relevant intraocular vascular proliferation factors. METHODS Sixty male specific pathogen free (SPF) Sprague-Dawley (SD) rats were randomly

OBJECTIVE This study was conducted to estimate the aminoacid levels in the vitreous of patients with proliferative diabetic retinopathy, and to correlate it with the adiponectin levels. Secondly to test if these amino acids can alter or induce adiponectin levels and its related factors in retinal

OBJECTIVE Metabolomics is the study of dysregulated metabolites in biological materials. We reviewed the use of the technique to elucidate the genetic and environmental factors that contribute to the development of diabetic retinopathy. RESULTS With regard to metabolomic studies of diabetic

In this study we tested the hypothesis that the Leu7Pro7 polymorphism in prepro neuropeptide Y (NPY) gene could be a risk marker for the development of diabetic retinopathy and analyzed a well characterized cohort of patients with Type 2 diabetes followed-up for 10 years from the time of diagnosis.

The leucine 7 to proline 7 (Leu7Pro) polymorphism in the signal peptide of NPY is associated with high blood lipid concentrations and accelerated rate of atherosclerosis as well as diabetic retinopathy. Also, healthy subjects with this polymorphism have increased NPY secretion during sympathetic

Neuropeptide Y (NPY) is an important neurotransmitter in the central and peripheral nervous systems. It has a regulatory role in cardiovascular and metabolic functions and control of hormone release. The leucine 7 to proline 7 (Leu7Pro) polymorphism in the signal peptide of prepro-NPY is associated

The effect of high glucose concentration (3 g/l) on bovine corneal total protein and collagen biosynthesis was studied, using 3H-proline incorporation in explant cultures with protein and collagen determinations. The high glucose concentration increased the incorporation of 3H-proline in total

Ischemic retinopathies, such as diabetic retinopathy (DR), retinopathy of prematurity and retinal vein occlusion are a major cause of blindness in developed nations worldwide. Each of these conditions is associated with early neurovascular dysfunction. However, conventional therapies target

Angiogenesis is characterized by the development of new vasculature from pre-existing vessels and plays a central role in physiological processes such as embryogenesis, wound healing and female reproductive function, as well as pathophysiologic events including cancer, rheumatoid arthritis and

Proliferative diabetic retinopathy (PDR) is the most severe form of diabetic retinopathy and, along with diabetic macular edema, is responsible for the majority of blindness in adults below the age of 65. Therapeutic strategies for PDR are ineffective at curtailing disease progression in all cases;
