glucose metabolite glyoxal induces senescence in

CiteSeerX RESEARCH ARTICLE Open Access

Among various RCS is the highly reactive dicarbonyl glyoxal (GO), which is a natural physiological metabolite produced by the autooxidation of glucose, and can form covalent adducts known as advanced glycation endproducts (AGE). We have previously reported that GO accelerates ageing and causes premature senescence in normal human skin fibroblasts.

Dose-Dependent Modulatory Effects of Insulin on Glucose

The elderly are prone to postprandial hyperglycemia that increases their cardiovascular risk. Although insulin therapy is necessary to treat diabetes, high plasma concentrations of insulin may cause the development of atherosclerosis and accelerate endothelial senescence. We assumed that high glucose causes stress-induced premature senescence and replicative senescence and examined the Elevated Levels of the Reactive Metabolite Methylglyoxal Apr 03, 2018 · They all relate to the regulation of central energy metabolism. Hence it is unlikely that MG is acting as a general, toxic metabolite. Indeed, animals with elevated levels of a toxic metabolite would be expected to have reduced longevity compared with control animals. Instead, Glo1 KO animals have an extended lifespan. Endurance Exercise Prevents Metabolic Distress-induced Results:Our data showed that EXE ameliorated HFD/HF-induced weight gain, fasting blood glucose levels, and visceral fat gain. More importantly, HFD/HF diet promoted cellular senescence, whereas EXE reversed it, evidenced by a reduction in the levels of p53, p21, p16, beta-galactosidase (SA-

Frontiers Brain Senescence Caused by Elevated Levels of

Sep 18, 2019 · Therefore, whether and how D-galactose induces senescence by elevated levels of reactive metabolite MG remain unclear. In the current study, we investigated the underlying mechanism of D-galactose-induced brain senescence. Results showed that long-term administration of D-galactose induced memory and study impairment. Glucose metabolite glyoxal induces senescence in Glucose metabolite glyoxal induces senescence in telomerase-immortalized human mesenchymal stem cells . By Larsen Simon, -immortalised mesenchymal stem cell line hMSC-TERT we have observed that an exposure of cells to 0.75 mM and 1 mM GO induces irreversible cellular senescence within 3 days. Induction of senescence in hMSC-TERT was Glycolytic cancer cells lacking 6-phosphogluconate Jul 30, 2012 · Fig. 6. 6PGD knockdown inhibits proliferation and induces senescence in the presence of glucose but not fructose. H1975 cells were treated with 2 g/ml doxycycline in glucose-free medium supplemented with 10% dialyzed FBS and 2 g/L fructose (fructose medium) for four days.

Chemistry Central Journal, 2012, Volume 6, Number 1. DOI:10.1186/1752-153X-6-18 [37] Glyoxal-Induced Premature Senescence in Human Glyoxal causes the formation of advanced glycation end products (AGEs) much faster than glucose (21)(22)(23)(24), thereby inducing cellular damage, apoptosis and senescence in different cell lines GlyoxalInduced Premature Senescence in Human Apr 18, 2007 · Simon Asbjørn Larsen, Moustapha Kassem, Suresh IS Rattan, Glucose metabolite glyoxal induces senescence in telomerase-immortalized human mesenchymal stem cells, Chemistry Central Journal, 10.1186/1752-153X-6-18, 6, 1, (2012).

Investigating the Glycating Effects of Glucose, Glyoxal

Jun 13, 2018 · Results showed that glyoxal, but not glucose or methylglyoxal, induced significant increases in CML levels on sperm and this correlated with an increase in 8-oxoguanine. Obesity and type-2 diabetes as inducers of premature Jul 27, 2018 · Cellular senescence is now considered as a major mechanism in the development and progression of various diseases and this may include metabolic diseases such as obesity and type-2 diabetes. The presence of obesity and diabetes is a major risk factor in the development of additional health conditions, such as cardiovascular disease, kidney disease and cancer. Overcoming Chronic Neck Pain:Postural Causes and A Glucose metabolite glyoxal induces senescence in telomerase-immortalized human mesenchymal stem cells (glyoxal, a highly reactive precursor of AGEs), Larsen et al.

Reaction of Glyoxal with 2-Deoxyguanosine, 2

Glyoxal (ethanedial) is an increasingly used industrial chemical that has been found to be mutagenic in bacteria and mammalian cells. In this study, the reactions of glyoxal with 2-deoxyguanosine, 2-deoxyadenosine, 2-deoxycytidine, cytidine, thymidine, and calf thymus DNA have been studied in aqueous buffered solutions. The nucleoside adducts were isolated by reversed-phase liquid Sugar-induced premature aging and altered differentiation The aim of this study was to induce senescence in keratinocytes using two sugars, glucose and glyoxal. Induction of senescence in early-passage NHEK was characterized by monitoring cell morphology, short-term growth characteristics, cell proliferation, and viability assay. Glucose metabolite glyoxal induces senescence in is the highly reactive dicarbonyl glyoxal (GO), which is a natural physiological metabolite produced by the auto-oxidation of glucose, and can form covalent adducts known as advanced glycation endproducts (AGE). We have previously reported that GO accelerates ageing and causes premature senescence in normal human skin fibroblasts.
