Diabetes is among the most prevalent diseases worldwide, of all the affected individuals a significant proportion of the population remains undiagnosed due to lack of specific symptoms early in this disorder and inadequate diagnostics. Diabetes and its associated sequela, i.e., Diabetic nephropathy, one of the microvascular complications of diabetes mellitus, is a leading cause of end-stage renal disease. Berberine is one of the main constituents of Coptidis Rhizoma and Cortex Phellodendri. In this study, we investigated the effects of berberine on fibronectin and collagen
Zinc (Zn) is a component of numerous enzymes that function in a wide range of biological process, including growth, development, immunity and intermediary metabolism. Zn may play a role in chronic states such as cardiovascular disease and diabetes mellitus. Zn acts as cofactor and for many enzymes
Adis CommentsPramlintide [AC 0137, AC 137, tripro-amylin, Symlin] is a synthetic human amylin analogue with proline substitutions at positions 25, 28 and 29, which limits the self-aggregation seen with native amylin. Pramlintide improves glycaemic control, and appears to reduce postprandial blood
Accumulation of brown products in long-lived proteins might be an important factor in determining long-term diabetic complications. Fluorescent chromophore 2-(2-furoyl)-4-(5)-(2-furanyl)-1H-imidazole (FFI), isolated from hydrolyzed brown products synthesized in vitro, was proposed as a specific
Diabetic complications are mostly vascular and involve alteration in blood vessel reactivity and permeability. The contribution of the latter dysfunction to the development of target organ damage has not been thoroughly examined. In this study, we verify the acute effect of three peptidase
For a better understanding of the processes leading to diabetic microangiopathy, type IV collagen from kidneys of patients with long-term diabetes was compared with the collagen from kidneys of sex- and age-matched controls. Type IV collagen from diabetic kidneys revealed no abnormalities in amino
Intracellular amine metabolite changes were quantified from hyperglycemic human aortic endothelial cells (HAECs) as a model for macrovascular complications of diabetes. Amines were selectively tagged using the N-hydroxysuccinimide ester (NHS) based isobaric tag DiART (Deuterium isobaric Amine
Insulin lispro is a recombinant insulin analogue with transposed amino acids (proline and lysine) at positions 28 and 29 near the C-terminus of the B-chain. The most prominent practical advantage of insulin lispro over human soluble insulin lies in its very rapid onset of action. This property
Neuropeptide Y (NPY) is a sympathetic neurotransmitter that plays a role in e.g. circulation, hormone release and angiogenesis. Earlier studies have shown that the Leucine 7 to Proline 7 (Leu7Pro) polymorphism of preproNPY is associated with increased risk for vascular complications in type 2
Many of the chronic complications of diabetes mellitus involve defects in the connective tissue such as poor wound healing, diminished bone formation, and decreased linear growth. Because collagen is the major protein component of these connective tissues, we examined collagen production in diabetic
Diabetic nephropathy is characterized by the chronic loss of kidney function due to high glucose renal levels. HK-2 proximal tubular cells are good candidates to study this disease. The aim of this work was to study an in vitro model of high glucose-induced metabolic alterations in HK-2 cells to
Glycine oxidase (GOX) from Bacillus subtilis is a new flavoprotein of great potential biotechnological use that catalizes the oxidative deamination of various amines (glycine, sarcosine, and N-ethyl-glycine) and D-amino acids (D-alanine and D-proline). However, its commercial application is hindered
Glycated hemoglobin (HbA1c), defined as hemoglobin (Hb) molecules having a stable adduct of glucose on the N-terminal of the β-chains, has been endorsed as a diagnostic tool for diabetes mellitus and a prediction indicator for the development of diabetes complications. Here we describe an accurate
Recent research has demonstrated that nonenzymatic glycation (the Maillard reaction) lead to the formation of carbonyl groups and advanced glycation end products (AGEs) in proteins. Such oxidative modifications are a major contributing factor to diabetic complications and aging. alpha-Aminoadipic
