Bayesian Analysis of Glucose Dynamics during the Oral Glucose Tolerance Test (OGTT) [PDF]

open access: yesarXiv, 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.

Cannabinoids Induce Pancreatic β-Cell Death by Directly Inhibiting Insulin Receptor Activation

open access: yesScience Signaling, 2012
Activation of cannabinoid 1 receptors prevents insulin receptors from promoting β-cell survival in the pancreas. Death by Cannabinoids Cannabinoid receptors are located in the brain and in the periphery, where they mediate effects on mood, appetite ...

An Artificial Insulin Receptor that Self-assembles and Works on a Gold Surface

open access: yesElectrochemistry
A 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

open access: yesFrontiers 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]

open access: yesBioSystems 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

open access: yesNature 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 ...

An Analytical Approach for Insulin-like Growth Factor Receptor 1 and Mammalian Target of Rapamycin Blockades in Ewing Sarcoma [PDF]

open access: yesarXiv, 2015
We present preliminary results that quantify network robustness and fragility of Ewing sarcoma (ES), a rare pediatric bone cancer that often exhibits de novo or acquired drug resistance. By identifying novel proteins or pathways susceptible to drug targeting, this formalized approach promises to improve preclinical drug development and may lead to ...

A model for insulin binding to the insulin receptor [PDF]

open access: yesEuropean Journal of Biochemistry, 1994
The affinities of a number of insulin analogues for the human insulin receptor, a truncated soluble form of the insulin receptor, and the human insulin‐like growth factor 1 receptor were determined. Insulin analogues with substitutions in the A13 or B17 positions were shown to have anomalous binding properties. This suggests that these positions, which

Robust Estimation of the Weighted Average Treatment Effect for A Target Population [PDF]

open access: yesarXiv, 2018
The weighted average treatment effect (WATE) is a causal measure for the comparison of interventions in a specific target population, which may be different from the population where data are sampled from. For instance, when the goal is to introduce a new treatment to a target population, the question is what efficacy (or effectiveness) can be gained ...

Phosphorylation of Ser307 in Insulin Receptor Substrate-1 Blocks Interactions with the Insulin Receptor and Inhibits Insulin Action*

open access: yesJournal of Biological Chemistry, 2002
Serine phosphorylation of insulin receptor substrate-1 (IRS-1) inhibits insulin signal transduction in a variety of cell backgrounds, which might contribute to peripheral insulin resistance.
