Bioactives of Artemisia dracunculus L enhance cellular insulin signaling in primary human skeletal muscle culture.
An alcoholic extract of Artemisia dracunculus L (PMI 5011) has been shown to decrease glucose and improve insulin levels in animal models, suggesting an ability to enhance insulin sensitivity. We sought to assess the cellular mechanism by which this botanical affects carbohydrate metabolism in primary human skeletal muscle culture. We measured basal and insulin-stimulated glucose uptake, glycog...
متن کاملBioactives of Artemisia dracunculus L. Mitigate the Role of Ceramides in Attenuating Insulin Signaling in Rat Skeletal Muscle Cells
Ectopic lipids in peripheral tissues have been implicated in attenuating insulin action in vivo. The botanical extract of Artemisia dracunculus L. (PMI 5011) improves insulin action, yet the precise mechanism is not known. We sought to determine whether the mechanism by which PMI 5011 improves insulin signaling is through regulation of lipid metabolism. After differentiation, cells were separat...
متن کاملPhosphorylation of insulin receptors solubilized from rat skeletal muscle.
A method has been developed to solubilize insulin receptors from skeletal muscles. Rat hindlimb muscles were rapidly frozen in liquid nitrogen, powdered, extracted with buffered Triton X-100, and partially purified by differential centrifugation followed by wheat germ agglutinin affinity chromatography. The solubilized receptors exhibit typical curvilinear Scatchard plots in insulin binding ass...
متن کاملIncreased AS160 phosphorylation, but not TBC1D1 phosphorylation, with increased postexercise insulin sensitivity in rat skeletal muscle.
A single exercise bout can increase insulin-independent glucose transport immediately postexercise and insulin-dependent glucose transport (GT) for several hours postexercise. Akt substrate of 160 kDa (AS160) and TBC1D1 are paralog Rab GTPase-activating proteins that have been proposed to contribute to these exercise effects. Previous research demonstrated greater AS160 and Akt threonine phosph...
متن کاملIncreased skeletal muscle capillarization enhances insulin sensitivity.
Increased skeletal muscle capillarization is associated with improved glucose tolerance and insulin sensitivity. However, a possible causal relationship has not previously been identified. Therefore, we investigated whether increased skeletal muscle capillarization increases insulin sensitivity. Skeletal muscle-specific angiogenesis was induced by adding the α1-adrenergic receptor antagonist pr...
