Identification and characterization of insulin-like growth factor receptors on adult rat cardiac myocytes: linkage to inositol 1,4,5-trisphosphate formation. [PDF]
, 1992 Cultured cardiac myocytes from adult Sprague-Dawley rats express both insulin-like growth factor-I (IGF-I) receptors and insulin-like growth factor-II/mannose 6-phosphate (IGF-II/Man6P) receptors and respond to IGF-I with a dose-dependent accumulation of

Minimizing Mitogenic Potency of Insulin Analogues Through Modification of a Disulfide Bond
Frontiers in Endocrinology, 2022 The mechanisms by which insulin activates the insulin receptor to promote metabolic processes and cellular growth are still not clear. Significant advances have been gained from recent structural studies in understanding how insulin binds to its receptor.

Magnesium supplementation enhances insulin sensitivity and decreases insulin resistance in diabetic rats [PDF]
Iranian Journal of Basic Medical Sciences, 2020 Objective(s): Diabetes mellitus has been suggested to be the most common metabolic disorder associated with magnesium deficiency. This study aimed to investigate the effects and mechanisms of magnesium supplementation on insulin receptor activity in ...

Functional selectivity of insulin receptor revealed by aptamer-trapped receptor structures
Nature Communications, 2022 DNA aptamers can activate insulin receptor as selective agonists or positive allosteric modulators. Here, authors determine structures of the insulin receptor bound to aptamers and provide a basis for the selective activation or allosteric regulation of ...

Molecular Genetics and Metabolism Reports, 2023 Severe insulin resistance can be caused by rare genetic defects in the insulin receptor known as insulin receptoropathies. These genetic defects cause a wide spectrum of clinical manifestations ranging from mild syndromes to lethal disorders. Among those

Insulin and insulin receptors in rodent brain [PDF]
Diabetologia, 1981 While insulin effects on the central nervous system (CNS) mediated through hypoglycaemia are well known, direct insulin effects on the CNS remain controversial. Recently, we found insulin receptors in all areas of the rat brain, with highest concentrations in the olfactory bulb, cerebral cortex and hypothalamus; all areas involved in feeding.

The Insulin Receptor Mediates Insulin’s Early Plasma Clearance by Liver, Muscle, and Kidney
Biomedicines, 2021 The role of the insulin receptor in mediating tissue-specific insulin clearance in vivo has not been reported. Using physiologic insulin doses, we measured the initial clearance rate (first 5 min) of intravenously injected ([125I]TyrA14)-insulin by ...

Insulin receptor has tyrosine kinase activity toward Shc in rat liver
Brazilian Journal of Medical and Biological Research, 1998 Insulin induces tyrosine phosphorylation of Shc in cell cultures and in insulin-sensitive tissues of the intact rat. However, the ability of insulin receptor (IR) tyrosine kinase to phosphorylate Shc has not been previously demonstrated.
