Structural Perspectives of Insulin Receptor Isoform-Selective Insulin Analogs [PDF]
Frontiers in Endocrinology, 2017 A significant drawback of the exogenous administration of insulin to diabetics is the non-physiological profile of insulin action resulting in the insufficient suppression of hepatic glucose production, which is the main contributing factor to diabetic ...

Modulation of the antagonistic properties of an insulin mimetic peptide by disulfide bridge modifications. [PDF]
J Pept Sci, 2023 Insulin mimetics with agonistic or antagonistic effects toward the receptor could find applications in treating diabetes or malignant diseases. As demonstrated, it is possible to modulate the functional properties of insulin receptor unnatural peptide ligands using disulfide bridge mimetics. Insulin is a peptide responsible for regulating the metabolic

Characterization of insulin crystalline form in isolated β-cell secretory granules [PDF]
Open Biology, 2022 Insulin is stored in vivo inside the pancreatic β-cell insulin secretory granules. In vitro studies have led to an assumption that high insulin and Zn2+ concentrations inside the pancreatic β-cell insulin secretory granules should promote insulin ...

Non-glycosylated IGF2 prohormones are more mitogenic than native IGF2 [PDF]
Communications Biology, 2023 Insulin-like Growth Factor-2 (IGF2) is important for the regulation of human embryonic growth and development, and for adults’ physiology. Incorrect processing of the IGF2 precursor, pro-IGF2(156), leads to the formation of two IGF2 proforms, big-IGF2(87)

A viral insulin-like peptide inhibits IGF-1 receptor phosphorylation and regulates IGF1R gene expression [PDF]
Molecular MetabolismObjective: The insulin/IGF superfamily is conserved across vertebrates and invertebrates. Our team has identified five viruses containing genes encoding viral insulin/IGF-1 like peptides (VILPs) closely resembling human insulin and IGF-1. This study aims
