Increased hepatic PDGF-AA signaling mediates liver insulin resistance in obesity associated type 2 diabetes [PDF]
arXiv, 2017 Type 2 diabetes (T2D) is closely linked with non-alcoholic fatty liver disease (NAFLD) and hepatic insulin resistance, but the involved mechanisms are still elusive. Using DNA methylome and transcriptome analyses of livers from obese individuals, we found that both hypomethylation at a CpG site in PDGFA (encoding platelet derived growth factor alpha ...

Molecular dynamics simulations reveal the role of ceramicine B as novel PPARγ partial agonist against type 2 diabetes [PDF]
arXiv, 2018 Peroxisome proliferator-activated receptors gamma (PPAR{\gamma}) are ligand-activated controllers of various metabolic actions and insulin sensitivity. PPAR{\gamma} is thus considered as an important target to treat type 2 diabetes. Available PPAR{\gamma} drugs (full agonists) have robust insulin-sensitizing properties but are accompanied by severe ...

Cellular Profile of Subfornical Organ Insulin Receptors in Mice
BiomoleculesBrain insulin receptor signaling is strongly implicated in cardiovascular and metabolic physiological regulation. In particular, we recently demonstrated that insulin receptors within the subfornical organ (SFO) play a tonic role in cardiovascular and ...

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

Frontiers in Endocrinology, 2013 Insulin and the insulin-like growth factors (IGF)-I and –II are closely related peptides important for regulation of metabolism, growth, differentiation and development. The IGFs exert their main effects through the IGF-I receptor.

Bayesian Analysis of Glucose Dynamics during the Oral Glucose Tolerance Test (OGTT) [PDF]
arXiv, 2020 In this paper, we propose a model of the dynamics of the blood glucose level during an Oral Glucose Tolerance Test (OGTT). This dynamic includes the action of insulin and glucagon in the glucose homeostasis process as the reaction of an oral stimulus.

An Artificial Insulin Receptor that Self-assembles and Works on a Gold Surface
ElectrochemistryA novel artificial insulin receptor was developed, that can self-assemble on a gold surface and alter its structure in response to insulin recognition via partial domains of the intrinsic insulin receptor.

Structural Perspectives of Insulin Receptor Isoform-Selective Insulin Analogs
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 ...

Characterization of the norepinephrine-activation of adenylate cyclase suggests a role in memory affirmation pathways. Overexposure to epinephrine inactivates adenylate-cyclase,a causal pathway for stress-pathologies [PDF]
BioSystems 100 (2010) p. 87-93, 2010 Incubation with noradrenaline (norepinephrine) of isolated membranes of rat's brain corpus striatum and cortex, showed that ionic-magnesium (Mg2+) is required for the neurotransmitter activatory response of Adenylate Cyclase [ATP pyrophosphate-lyase (cyclizing), (EC 4.6.1.1)], AC.An Mg2+-dependent response to the activatory effects of adrenaline, and ...

The beta secretase BACE1 regulates the expression of insulin receptor in the liver
Nature Communications, 2018 A soluble form of insulin receptor in human plasma has been previously reported. Here the authors demonstrate that insulin receptor is cleaved by BACE1 that can regulate biological active insulin receptor levels in a glucose concentration-dependent ...
