Abstract:
Insulin and its A and B chain increased the quantity of intracellular PAS-positive material (glycogen) in tetrahymena, whereas the combined A+B chains decreased it. Imprinting—previous interaction—with insulin, its A and B chains in themselves and with the A+B chain increased the hormone binding capacity of tetrahymena, but the functional effect of imprinting (storage or breakdown of glycogen) showed a different tendency with insulin and A+B chain on the one hand, and A chain and B chain on the other. Since the imprinting potential of a molecule promotes the induction of receptor formation, th

Abstract:
In a previous study [Muir, Offord & Davies (1986) Biochem. J. 237, 631-637] the chromatographic and electrophoretic behaviour of a major labelled fragment in the degradation of tritiated insulins by insulin proteinase were used to locate the probable sites of cleavage which had produced this fragment. In order to define these cleavage sites more precisely, authentic markers for the fragments which would be produced by cleavages at, or adjacent to, the most likely sites have now been synthesized. These markers were compared with labelled fragments of the A- and B-chains of insulin produced

Abstract:
In this study, we investigated the folding pathway of insulin precursor and compared it with that of insulin-like growth factor I (IGF-I). The intra-A chain disulphide bond was found to form early in insulin precursor folding, whereas the corresponding disulphide bond in IGF-I formed late. Intra-A chain disulphide-bond deleted [A6, A11-Ser] proteins, including proinsulin, insulin, and A chain, were employed for this investigation. Under the same conditions the recombination yield of insulin from S-sulphonates of native A and B chains was 22%, while the yield of [A6, A11-Ser] insulin from S-sul

Abstract:
The B chain of mammalian insulins contains appropriately spaced amino acids that predict recognition by T cells. However, all T cell clones from an HLA-DR1, Dw6 diabetic donor recognize epitopes associated with the A chain, and the B chain was found to inhibit these responses. Effective intramolecular competition at the level of the APC, not a direct effect on the T cell, is responsible for the inhibition. Insulin B chain contains two clusters of amino acid homology with the TCR beta chain and B chain peptides lacking these clusters do not compete for antigen presentation. A hole in the repert

Abstract:
Glargine became the first long-acting insulin analogue. Glargine was designed to meet basal insulin requirements throughout the day with a single injection. Pharmacokinetics of insulin glargine is characterized by biotransformation into metabolites M1 and M2 that transforms the B chain of glargine so it is similar to the B chain of human insulin. Plasma concentrations of active M1 and M2 metabolites have no pronounced peaks during the day, resulting in lower glucose variability and hypoglycaemia risk when compared with NPH insulin. The metabolic activities of M1 and M2 metabolites are similar

Abstract:
Insulin and insulin-like growth factor 1 (IGF-1) are closely related hormones involved in the regulation of metabolism and growth. They elicit their functions through activation of tyrosine kinase–type receptors: insulin receptors (IR-A and IR-B) and IGF-1 receptor (IGF-1R). Despite similarity in primary and three-dimensional structures, insulin and IGF-1 bind the noncognate receptor with substantially reduced affinity. We prepared [d-HisB24, GlyB31, TyrB32]-insulin, which binds all three receptors with high affinity (251 or 338% binding affinity to IR-A respectively to IR-B relative to insuli

Abstract:
The use of electromagnetic devices such as microwave ovens and mobile phones has certainly brought convenience to our lives. At the same time, the proliferation of said devices has increased public awareness of the potential health hazards. It is generally assumed that there is little or no risk associated with the use of electromagnetic devices, based on the small amount of power associated with those devices. However, case studies on animals indicate that the risk cannot be entirely ruled out. It has long been known that proteins are sensitive to stress, arising from various sources suc

In Chapter I is a general description of novel metal complexes which hydrolytically cleave peptides, proteins, DNA, and other biological molecules. These reagents are becoming the more important as potential therapeutic agents. A panel of ligands was investigated for coordination to ZrIV and other metals in groups 4, 5, and 6 to effect the greatest degree of hydrolysis. Chapter II describes a ZrIV complex which is capable of hydrolyzing a 30 amino acid peptide, insulin chain B, with amino acid specificity.

Cette dernière étape peut se faire par des méthodes photométriques ou par spectrométrie de masse (MS).
