Computational analyses to investigate pathogenicity and molecular dynamics (MD) were performed for GCK-E372D and for previously described homozygous mutations associated with mild (n = 2) or severe (n = 1) hyperglycemia, used as references.
The intervention also suppressed serum monocyte chemotactic protein-1 and interleukin-6 levels, which are proinflammatory cytokines involved in the development of insulin resistance and hyperglycemia.
Non-peptidyl small molecule, adenosine, 5'-Se-methyl-5'-seleno-, 2',3'-diacetate, activates insulin receptor and attenuates hyperglycemia in type 2 diabetic Lepr<sup>db/db</sup> mice.
The study presented a simpler and more reliable way in studying the properties of glucokinase and its effectors, providing guidelines of effector developments for hyperglycemia and hypoglycemia treatment.
<i>In vitro</i> experiments in rat macrophages showed that hyperglycemia treatment suppresses Nrf2 activation, resulting in oxidative stress with decreased expression of antioxidant genes, including NAD(P)H:quinone oxidoreductase 1 and heme oxygenase 1, together with increased secretion of proinflammatory cytokines, including interleukin 1β (IL1β), IL6, and monocyte chemoattractant protein-1.
The clinical characteristics of patients with GK-activating mutations or GK regulatory protein (GKRP) loss-of-function mutations suggest that a hepatoselective GK activator (GKA) that does not activate GK in β cells or affect the GK-GKRP interaction may reduce hyperglycemia in patients with type 2 diabetes while limiting hypoglycemia and liver-associated adverse effects.
The untreated diabetic group showed hyperglycemia and increased diuresis, creatinine clearance, proteinuria, glycosuria and urinary excretion of <i>N</i>-acetyl-β-d-glucosaminidase (NAG), as well as increased oxidative stress and the expression of interleukin 1β (IL-1β), IL-6, nuclear factor kappa beta (NFκβ) and transforming growth factor-β1 (TGF-β1) in plasma and kidney.
We found that multiple cave populations carry a mutation in the insulin receptor that leads to decreased insulin binding in vitro and contributes to hyperglycaemia.
Our findings provide evidence that a single bout of exhaustive exercise protects against acute olanzapine-induced hyperglycemia and that IL-6 is neither sufficient, nor required for exercise to protect against increases in blood glucose with olanzapine treatment.
We hypothesize that not all MODY 2 affected fetuses need the same levels of hyperglycemia to have an appropriate growth, maybe because different kinds of GCK mutations may result in different phenotypes.
We found that mice with deletion of the insulin receptor alone showed not only hyperglycemia but also a 70% decrease in plasma insulin-like growth factor 1 and delayed growth during the first 2 months of life, a 24-fold increase in the soluble leptin receptor and a 19-fold increase in plasma leptin levels.
Moreover, compared with control group the expression of IL1R1 and IL-6 genes both were downregulated in individuals with moderately high blood glucose levels by 2.38 (p = 0.0365) and 4.34 fold (p = 0.0027), respectively.
Previously we demonstrated that NEU1 activates the insulin receptor (IR) and that NEU1-deficient CathA<sup>S190A-Neo</sup> mice (hypomorph of the NEU1 activator protein, cathepsin A/CathA) on a high-fat diet (HFD) develop hyperglycaemia and insulin resistance faster than wild-type animals.
The hyperglycemia can directly promote an inflammatory state where the increase C-reactive (CRP) and cytokines, such as interleukins (IL-1 and IL-6), which contribute to the development of cardiovascular diseases.
However, the effect of naturally occurring GCK mutations on the pathogenesis for MODY2hyperglycaemia remains largely unclear, especially in the Asian population.
Improvement of hyperglycemia in a murine model of insulin resistance and high glucose- and inflammasome-mediated IL-1β expressions in macrophages by silymarin.
Pre-adipocytes and adipocytes in this state secrete pro-inflammatory adipokines, such as interleukin 6 (IL-6), which induce insulin resistance and hyperglycemia.
Streptozotocin (STZ)-induced type 2 DM is used as a model of human type 2 DM in which peripheral insulin resistance, increased plasma interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) and hyperglycemia occurs.
In summary, our observations demonstrate that the activation of either IL-6 classic or trans-signalling advances podocyte harming under hyperglycaemia.
