Increased proinsulin (PI) compared to C-peptide (CP) concentrations have been reported, both prior to type 1 diabetes mellitus (T1D) onset, as well as early in disease. In this pilot study, we sought to define the normal PI secretion in a healthy cohort and compare this to a local T1D cohort and a separate well-defined nationally representative T1D cohort with measurable CP.

Emerging evidence shows that non-nutritive sweeteners might induce glucose intolerance. This study aims to determine the effects of chronic exposure to sucralose on glycemic response, insulin secretio...
To quantify the proportion of current US gun owners who are new to owning firearms and compare new versus long-standing gun owners with respect to their firearms and firearm-related behaviors.
Expression of fat mass and obesity-associated gene (FTO) and ADP-ribosylation factor-like 15 (ARL15) in human islets is inversely correlated with HbA. However, their impact on insulin secretion is sti...
Key features for progression to pancreatic β-cell failure and disease are loss of glucose responsiveness and an increased ratio of secreted proinsulin to insulin. Proinsulin and insulin are stored in...
Insulin synthesis in pancreatic β-cells is initiated as preproinsulin. Prevailing glucose concentrations, which oscillate pre- and postprandially, exert major dynamic variation in preproinsulin biosy...
The aim of the study is to show that treatment with Glargine will lead to an improvement in beta cell function especially within times of maximal beta cell stress occurring after a meal. F...
Glucagon like peptide 1 is produced in enteroendocrine L cells in the small intestine stimulated by peroral food intake. GLP-1 induces insulin secretion, and analogues are used in the trea...
study hypothesis: treatment with GLP-1 and/or GIP is able to potentiate the maximal stimulated insulin secretion even in c-peptide negative type-1 diabetic patients classified as having no...
The purpose of this study is to determine the functional significance of sweet taste receptors in the secretion of GI satiety peptides by using a specific sweet taste receptor antagonist t...
We aim to demonstrate that oral administration of glibenclamide stimulates pancreatic glucagon secretion during hypoglycemia in insulin-deficient (C-peptide negative) patients with type 1 ...
The middle segment of proinsulin that is between the N-terminal B-chain and the C-terminal A-chain. It is a pancreatic peptide of about 31 residues, depending on the species. Upon proteolytic cleavage of proinsulin, equimolar INSULIN and C-peptide are released. C-peptide immunoassay has been used to assess pancreatic beta cell function in diabetic patients with circulating insulin antibodies or exogenous insulin. Half-life of C-peptide is 30 min, almost 8 times that of insulin.
A pancreatic polypeptide of about 110 amino acids, depending on the species, that is the precursor of insulin. Proinsulin, produced by the PANCREATIC BETA CELLS, is comprised sequentially of the N-terminal B-chain, the proteolytically removable connecting C-peptide, and the C-terminal A-chain. It also contains three disulfide bonds, two between A-chain and B-chain. After cleavage at two locations, insulin and C-peptide are the secreted products. Intact proinsulin with low bioactivity also is secreted in small amounts.
A 36-amino acid peptide produced by the L cells of the distal small intestine and colon. Peptide YY inhibits gastric and pancreatic secretion.
A 36-amino acid peptide present in many organs and in many sympathetic noradrenergic neurons. It has vasoconstrictor and natriuretic activity and regulates local blood flow, glandular secretion, and smooth muscle activity. The peptide also stimulates feeding and drinking behavior and influences secretion of pituitary hormones.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
