Connecting Peptide, or C-peptide, is a product of the insulin prohormone, and is released with and in amounts equimolar to those of insulin. While it was once thought that C-peptide was biologically inert and had little biological significance beyond its role in the proper folding of insulin, it is now known that C-peptide binds specifically to the cell membranes of a variety of tissues and ini...
OBJECTIVE To clarify the association between C-peptide index and pancreatic beta cell function and diabetes. MATERIALS AND METHODS We carried out a retrospective analysis of 1021 patients aged 27 to 80 without diabetes from January 2012 to January 2016. All subjects underwent a 75-g oral glucose tolerance test. Blood samples were drawn at 0, 30, 60, 120 and 180 min after the glucose load. Pla...
An automated continuous-flow liquid-phase peptide synthesizer for preparing C-terminal free peptides was developed. This system includes aqueous workup, concentration, and in-line NIR monitoring.
We isolated the human C-type natriuretic peptide gene and identified the peptide in the brain. The human C-type natriuretic peptide gene appeared to be composed of at least two exons and one intron. In the 5'-flanking region, there is an array of cis elements (an inverted CCAAT box, two GC boxes, and a cyclic AMP response element-like sequence) that is not present in upstream sequences of the a...
Specific binding of the C-peptide of proinsulin was evaluated using a transplantable NEDH rat islet cell tumour predominantly composed of insulin-secreting B-cells. Cultured tumour B-cells exhibited greater than 90% viability assessed by trypan blue exclusion, and retained the ability to form tumours with accompanying hypoglycaemia and hyperinsulinaemia after reimplantation. During binding expe...
1. C-type natriuretic peptide is a neuropeptide, which is also produced by the vascular endothelial cells. Plasma immunoreactive C-type natriuretic peptide concentrations in patients with various diseases have not yet been studied. 2. Plasma immunoreactive C-type natriuretic peptide concentrations were studied by radioimmunoassay in normal subjects, patients with congestive heart failure, non-d...
Estimation of serum C-peptide (SCP) is used as a measure of endogenous insulin secretion in type 2 diabetes mellitus (T2DM). Urinary CPeptide (UCP) and urinary C-Peptide creatinine ratio (UCPCR) are non invasive, simple and easily reproducible tests which may be considered as an alternative for SCP. In our study we estimated fasting serum C-peptide, urinary C-peptide and UCPCR in Type 2 Diabete...
Proinsulin C-peptide treatment can partially prevent nerve dysfunction in type 1 diabetic rats and patients. This could be due to a direct action on nerve fibers or via vascular mechanisms as C-peptide stimulates the nitric oxide (NO) system and NO-mediated vasodilation could potentially account for any beneficial C-peptide effects. To assess this further, we examined neurovascular function in ...
