Muscle contraction causes an increase in activity of 5'-AMP-activated protein kinase (AMPK). This study was designed to determine whether chronic chemical activation of AMPK will increase mitochondrial enzymes, GLUT-4, and hexokinase in different types of skeletal muscle of resting rats. In acute studies, rats were subcutaneously injected with either 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICAR; 1 mg/g body wt) in 0.9% NaCl or with 0.9% NaCl alone and were then anesthetized for…

AMP-activated protein kinase activates transcription of the UCP3 and HKII genes in rat skeletal muscle.
TLDR
Evidence is provided that AMPK signaling is linked to the transcriptional regulation of select metabolic genes in skeletal muscle by a single-leg arterial infusion technique employed in fully conscious rats.
Role of AMP-activated protein kinase in the molecular adaptation to endurance exercise.
TLDR
Observations lend credence to the hypothesis that AMPK activation induced by muscle contraction is responsible in part for adaptations to endurance exercise training.
Effect of acute activation of 5'-AMP-activated protein kinase on glycogen regulation in isolated rat skeletal muscle.
TLDR
The results suggest that AMPK does not mediate contraction- Stimulated glycogen synthesis or glycogenolysis in skeletal muscle and also that acute AMPK activation leads to an increased glycolytic flux by antagonizing contraction-stimulated glycogens synthesis.
Contraction-mediated phosphorylation of AMPK is lower in skeletal muscle of adenylate kinase-deficient mice.
TLDR
It is suggested that reduced formation of AMP during contractions in skeletal muscle of AK1-/- mice results in reduced phosphorylation of AMPK, and altered AMPK signaling was not apparent in the phosphorylated status of acetyl CoA carboxylase, a typical marker of AM PK activity.
AMP-activated protein kinase activation prevents denervation-induced decline in gastrocnemius GLUT-4.
TLDR
Evidence is provided that some effects of denervation may be prevented by chemical activation of the appropriate signaling pathways as well as the extent ofDenervation-induced muscle atrophy was similar in AICAR-treated vs. saline-treated rats.
Chronic activation of AMP kinase results in NRF-1 activation and mitochondrial biogenesis.
TLDR
Chronic phosphocreatine depletion during beta-GPA supplementation led to the activation of muscle AMPK that was associated with increased NRF-1 binding activity, increased cytochrome c content, and increased muscle mitochondrial density.
Muscle contractions, AICAR, and insulin cause phosphorylation of an AMPK-related kinase.
TLDR
The data suggest that increased phosphorylation of ARK5 by muscle contractions or exposure to AICAR is insufficient to activate ARK 5 in skeletal muscle, suggesting that some other modification may be necessary to its activity in muscle.
Chronic AMP-activated protein kinase activation and a high-fat diet have an additive effect on mitochondria in rat skeletal muscle.
TLDR
Data show that chronic chemical activation of AMPK and a high-fat diet have a muscle type specific additive effect on markers of fatty acid oxidation, the citric acid cycle, the electron transport chain, and transcriptional regulation.
AMP‐activated protein kinase in contraction regulation of skeletal muscle metabolism: necessary and/or sufficient?
TLDR
Evidence supporting a necessary and/or sufficient role of AMPK in a broad spectrum of skeletal muscle contraction‐relevant processes, including glucose uptake, glycogen synthesis, post‐exercise insulin sensitivity, fatty acid (FA) uptake, intramuscular triacylglyceride hydrolysis, FA oxidation, suppression of protein synthesis, proteolysis, autophagy and transcriptional regulation of genes relevant to promoting an oxidative phenotype are critically examined.
Effect of AICAR treatment on glycogen metabolism in skeletal muscle.
TLDR
AICAR treatment does not promote glycogen accumulation in skeletal muscle in vivo by altering glycogen synthase and glycogen phosphorylase, and the increased glycogen is due to the well-known effects of AICAR to increase glucose uptake.

Chronic activation of 5'-AMP-activated protein kinase increases GLUT-4, hexokinase, and glycogen in muscle.
TLDR
Chronic chemical activation of AMPK results in increases in GLUT-4 protein, hexokinase activity, and glycogen, similarly to those induced by endurance training.
5' AMP-activated protein kinase activation causes GLUT4 translocation in skeletal muscle.
TLDR
Evidence is provided that the increased glucose uptake observed with AMPK activation by AICA-riboside in perfused rat hindlimb muscles is due to an increase in the translocation of GLUT4 to surface membranes.
AICA riboside increases AMP-activated protein kinase, fatty acid oxidation, and glucose uptake in rat muscle.
TLDR
Evidence is provided that decreases in muscle content of malonyl-CoA can increase the rate of fatty acid oxidation, and perfusion with medium containing AICAR was found to activate AMPK in skeletal muscle, inactivate ACC, and decrease malony l-coA.
Inactivation of acetyl-CoA carboxylase and activation of AMP-activated protein kinase in muscle during exercise.
TLDR
The activation of the AMP-activated protein kinase with consequent phosphorylation and inactivation of ACC may be one of the primary events in the control of malonyl-CoA and hence fatty acid oxidation during exercise.
Evidence for 5′AMP-Activated Protein Kinase Mediation of the Effect of Muscle Contraction on Glucose Transport
TLDR
Data suggest that AICAR and contraction stimulate glucose transport by a similar insulin-independent signaling mechanism and are consistent with the hypothesis that AMPK is involved in exercise-stimulated glucose uptake.
Increased expression of GLUT-4 and hexokinase in rat epitrochlearis muscles exposed to AICAR in vitro.
TLDR
Examination of the effect of incubating rat epitrochlearis muscles in culture medium in the presence or absence of 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) provides strong evidence in support of the hypothesis that the activation of AMPK that occurs in muscle during exercise is involved in mediating the adaptive increases in GLUT-4 and hexokinase.

TLDR
Increased recruitment of the AMPK signaling system, either by exercise or pharmaceutical activators, may be effective in correcting insulin resistance in patients with forms of impaired glucose tolerance and Type 2 diabetes resulting from defects in the insulin signaling cascade.
Adaptation of muscle to creatine depletion: effect on GLUT-4 glucose transporter expression.
TLDR
Results provide evidence that chronic creatine depletion increases GLUT-4 expression by pretranslational mechanisms and support the hypothesis that the levels of mitochondrial enzymes, hexokinase, andglucose transport activity maximally stimulated by insulin was increased in parallel with GLut-4 protein concentration in the epitrochlearis.
Biochemical adaptation in the skeletal muscle of rats depleted of creatine with the substrate analogue beta-guanidinopropionic acid.
TLDR
It is concluded that fast-twitch muscles adapt by a combination of decreasing diffusion distances, increasing aerobic capacity and decreasing glycolytic potential, and that fibre-type-specific thresholds exist for the transformation response.
Exercise induces a transient increase in transcription of the GLUT-4 gene in skeletal muscle.
TLDR
It is proposed that the increase in GLut-4 mRNA evident with extended periods of training may result from a shift to pretranslational control and is the cumulative effect of repeated postexercise transient increases in GLUT-4 gene transcription.
