Since relative or absolute insulin deficiency and insulin insensitivity are involved in the aetiology of non-insulin-dependent diabetes mellitus (NIDDM), we examined whether patients with NIDDM exhibit genetic variability in the coding region of insulin receptor substrate-1 (IRS-1), a candidate gene
In this work, we studied the changes in human skin collagen occurring in diabetes mellitus and liver cirrhosis. The original methodology, based on the determination of the amino acids proline, 4-hydroxyproline, hydroxylysine, glycine and alanine, allowed us to reveal in skin a change in collagen in
Diabetes mellitus, commonly referred to as diabetes, is a medical condition associated with abnormally high levels of glucose (or sugar) in the blood. Keeping this view, we demonstrate the phylogenetic motifs (PMs) identification in type 2 diabetes mellitus very likely corresponding to protein
Type 2 diabetes mellitus is a common disabling disease with onset in middle-aged individuals, caused by an imbalance between insulin production and action. Genetic studies point to major genetic components, but, with the exception of maturity-onset diabetes of the young (MODY), specific diabetes
Insulin lispro, a recombinant insulin analogue, is identical to human insulin except for the transposition of proline and lysine at positions 28 and 29 in the C-terminus of the B chain. The resultant reduced capacity for self-association in solution translates into more rapid absorption of insulin
Mitochondrial respiratory function in a patient with maternally inherited type 2 diabetes mellitus and hypertrophic cardiomyopathy associated with heteroplasmic mitochondrial DNA (mtDNA) C3310T mutation, which replaces the second amino acid of NADH dehydrogenase 1 (ND1) from a hydrophobic Proline to
OBJECTIVE
Recent studies have implicated the potential importance of peroxisome proliferator-activated receptors as a molecular mechanism involved in atherothrombosis. A common alanine (A) for proline (P) substitution at codon 12 in the peroxisome proliferator activated receptor gamma-2 gene
Peroxisome proliferator activated receptor-gamma (PPARgamma) is a nuclear receptor that regulates adipocyte differentiation and possibly lipid metabolism and insulin sensitivity. Therefore, PPARgamma is a promising candidate gene for several disorders including diabetes, obesity, and
Type 2 diabetes mellitus (T2DM) is characterized by chronic hyperglycemia associated with insulin resistance and relative insulin deficiency. T2DM is believed to be attributable to the combined effect of genetic and environmental factors. Peroxisome proliferator-activated receptor gamma 2 (PPARγ2)
The effect of insulin on the transport of proline has been studied in cultured fibroblasts from normal individuals, non-insulin-dependent diabetic patients, and patients with Werner syndrome. In fibroblasts from normal individuals and those with diabetes mellitus, incubation with 10(-7) M insulin
A new method for prolidase (PLD, EC 3.4.13.9) activity assay was developed based on the determination of proline produced from enzymatic reaction through capillary electrophoresis (CE) with tris(2,2'-bipyridyl)ruthenium(II) [Ru(bpy)3(2+)] electrochemiluminescence detection (ECL). A detection limit
We investigated longitudinal change in the amino acid (AA) profile in type 1 diabetes mellitus (DM) using AKITA mice, which develop DM as a result of insulin deficiency. The plasma concentrations of valine, leucine, isoleucine, as well as the total branched chain amino acids, alanine, citrulline and
Amylin is a pancreatic hormone cosecreted along with insulin and involved in pancreatic amyloidosis and β-cell apoptosis in diabetic cats and humans. Amylin is usually elevated in early stages of type 2 diabetes but recently was found to be increased in acute and chronic pancreatitis in humans.
N-Cbz-4,5-dehydro-L-prolineamide or N-Boc-4,5-dehydro-L-prolineamide are alternative key intermediates for the synthesis of saxagliptin, a dipeptidyl peptidase IV (DPP4) inhibitor recently approved for treatment of type 2 diabetes mellitus. An efficient biocatalytic method was developed for
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
