Nettet18. des. 2024 · One recent study with insulin receptor muscle over-expression (IRMOE) demonstrated similarities with our in vitro model, such as increased basal AKT phosphorylation and impaired insulin-stimulated AKT phosphorylation, indicative of a significant level of post-receptor insulin resistance. 31 The second study used the … Elevated levels of the hormone insulin in the blood trigger downregulation of the associated receptors. When insulin binds to its receptors on the surface of a cell, the hormone receptor complex undergoes endocytosis and is subsequently attacked by intracellular lysosomal enzymes. The internalization of the insulin molecules provides a pathway for degradation of the hormone as well as for regulation of the number of sites that are available for binding on the cell surface. At …

Nettet25. feb. 1981 · On the mechanism of ligand-induced down-regulation of insulin receptor level in the liver cell. NettetInsulin-stimulated NO-dependent skeletal muscle microvascular dilatation involves several mechanisms including activation of the insulin receptor, IRS1 and 2, and the PI3K-Akt-eNOS pathway [32,88]. Decreased expression of IRS-1 and 2 and decreased phosphorylation of Akt and eNOS are key hallmarks of vascular insulin resistance [37,48].

NettetThe insulin receptor and IRS proteins are negatively regulated by multiple systems, such as ligand-induced downregulation, tyrosine protein phosphatases, and serine phosphorylation. Phosphatases also regulate the subsequent steps in the associated protein kinase cascades.
