The effect of curcumin on PI3K/Akt and AMPK pathways in insulin resistance induced by fructose

Türk Biyokimya Dergisi
Excessive fructose consumption is recognized to elevate insulin resistance in animals and humans. In our study, we aimed to assess the possible consequences of curcumin (curc) treatment applied to rat models of fructose-induced insulin resistance on ...

Therapeutic potential of okra (Abelmoschus esculentus) in dysglycaemia and metabolic dysfunction: A systematic review and meta‐analysis across the diabetes spectrum

Experimental Physiology, EarlyView.
Abstract The aim of this systematic review and meta‐analysis was to evaluate comprehensively the therapeutic potential of Abelmoschus esculentus (okra) supplementation across the diabetes spectrum of key metabolic risk factors. A search was conducted in PubMed, Scopus, Web of Science, EMBASE and the Cochrane Library, up to 23 July 2025, to identify ...

GLUT4 protein expression in obese and lean 12-month-old rats: insights from different types of data analysis

Brazilian Journal of Medical and Biological Research, 2001
GLUT4 protein expression in white adipose tissue (WAT) and skeletal muscle (SM) was investigated in 2-month-old, 12-month-old spontaneously obese or 12-month-old calorie-restricted lean Wistar rats, by considering different parameters of analysis, such ...

Divergent skeletal muscle metabolite exchange in insulin‐like growth factor‐1‐stimulated myotubes and resistance‐exercised human muscle

Experimental Physiology, EarlyView.
Abstract Skeletal muscle hypertrophy requires a substantial nutrient influx for biomass accretion, but global metabolite exchange during growth is poorly characterized. Therefore, we profiled the metabolite uptake and release in insulin‐like growth factor‐1 (IGF‐1)‐stimulated C2C12 myotubes and human muscle 24 h after resistance exercise ...

GLUT4 ready to go

The Journal of Cell Biology, 2005
Vesicles containing the glucose transporter GLUT4 travel rapidly on a microtubule network that lies just under the plasma membrane in resting cells, according to results from Lizunov et al. (page 481). The vesicles occasionally touch the plasma membrane and, when stimulated by insulin, quickly fuse with it.

Sustained exposure of L6 myotubes to high glucose and insulin decreases insulin-stimulated GLUT4 translocation but upregulates GLUT4 activity.

, 2002
Hyperglycemia and hyperinsulinemia are cardinal features of acquired insulin resistance. In adipose cell cultures, high glucose and insulin cause insulin resistance of glucose uptake, but because of altered GLUT4 expression and contribution of GLUT1 to ...

Hyperglycaemia‐induced reactive oxygen species production in cardiac ventricular myocytes differs among mammals

The Journal of Physiology, EarlyView.
Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

Fetal glucose availability: a key regulator of the metabolic, hormonal and contractility profiles of the fetal sheep heart

The Journal of Physiology, EarlyView.
Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...
