AMP-Activated Protein Kinases
Intracellular signaling protein kinases that play a signaling role in the regulation of cellular energy metabolism. Their activity largely depends upon the concentration of cellular AMP which is increased under conditions of low energy or metabolic stress. AMP-activated protein kinases modify enzymes involved in LIPID METABOLISM, which in turn provide substrates needed to convert AMP into ATP.
A biguanide hypoglycemic agent with actions and uses similar to those of METFORMIN. Although it is generally considered to be associated with an unacceptably high incidence of lactic acidosis, often fatal, it is still available in some countries.

A biochemical messenger and regulator, synthesized from the essential amino acid L-TRYPTOPHAN. In humans it is found primarily in the central nervous system, gastrointestinal tract, and blood platelets. Serotonin mediates several important physiological functions including neurotransmission, gastrointestinal motility, hemostasis, and cardiovascular integrity. Multiple receptor families (RECEPTORS, SEROTONIN) explain the broad physiological actions and distribution of this biochemical mediator.
Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)

Absorption, metabolism, and excretion of 14C-temozolomide following oral administration to patients with advanced cancer. (1/623)The purpose of this study is to characterize the absorption, metabolism, and excretion of carbon 14-labeled temozolomide (14C-TMZ) administered p.o. to adult patients with advanced solid malignancies. On day 1 of cycle 1, six patients received a single oral 200-mg dose of 14C-TMZ (70.2 microCi). Whole blood, plasma, urine, and feces were collected from days 1-8 and on day 14 of cycle 1. Total radioactivity was measured in all samples. TMZ, 5-(3-methyltriazen-1-yl)imidazole-4-carboxamide (MTIC), and 4-amino-5-imidazole-carboxamide (AIC) concentrations were determined in plasma, and urine and plasma samples were profiled for metabolite/degradation products. Maximum TMZ plasma concentrations were achieved between 0.33 to 2 h (mean, 1.2 h), and half-life, apparent volume of distribution, and oral clearance values averaged 1.9 h, 17 liters/m2, and 104 ml/min/m2, respectively. A first-order absorption, one-compartment linear model, which included first-order formation of MTIC from TMZ and elimination of MTIC via degradation to AIC, and a peripheral distribution compartment for AIC, adequately described the plasma TMZ, MTIC, and AIC concentrations. MTIC systemic clearance was estimated to be 5384 ml/min/m2, and the half-life was calculated to be 2.5 min. Metabolite profiles of plasma at 1 and 4 h after treatment showed that 14C-derived radioactivity was primarily associated with TMZ, and a smaller amount was attributed to AIC. Profiles of urine samples from 0-24 h revealed that 14C-TMZ-derived urinary radioactivity was primarily associated with unchanged drug (5.6%), AIC (12%), or 3-methyl-2,3-dihydro-4-oxoimidazo[5,1-d]tetrazine-8-carboxyl ic acid (2.3%). The recovered radioactive dose (39%) was principally eliminated in the urine (38%), and a small amount (0.8%) was excreted in the feces. TMZ exhibits rapid oral absorption and high systemic availability. The primary elimination pathway for TMZ is by pH-dependent degradation to MTIC and further degradation to AIC. Incomplete recovery of radioactivity may be explained by the incorporation of AIC into nucleic acids. (+info)
Apoptosis induced by growth factor withdrawal in fibroblasts overproducing fructose 2,6-bisphosphate. (2/623)Fructose 2,6-bisphosphate is a potent endogenous stimulator of glycolysis. A high aerobic glycolytic rate often correlates with increased cell proliferation. To investigate this relationship, we have produced clonal cell lines of Rat-1 fibroblasts that stably express transgenes coding for 6-phosphofructo-2-kinase, which catalyzes the synthesis of fructose 2,6-bisphosphate, or for fructose 2,6-bisphosphatase, which catalyzes its degradation. While serum deprivation in culture reduced the growth rate of control cells, it caused apoptosis in cells overproducing fructose 2,6-bisphosphate. Apoptosis was inhibited by 5-amino-4-imidazolecarboxamide riboside, suggesting that 5'-AMP-activated protein kinase interferes with this phenomenon. (+info)
Effect of AMPK activation on muscle glucose metabolism in conscious rats. (3/623)The effect of AMP-activated protein kinase (AMPK) activation on skeletal muscle glucose metabolism was examined in awake rats by infusing them with 5-aminoimidazole-4-carboxamide 1-beta-D-ribofuranoside (AICAR; 40 mg/kg bolus and 7.5 mg. kg-1. min-1 constant infusion) along with a variable infusion of glucose (49.1 +/- 2.4 micromol. kg-1. min-1) to maintain euglycemia. Activation of AMPK by AICAR caused 2-deoxy-D-[1,2-3H]glucose (2-DG) uptake to increase more than twofold in the soleus and the lateral and medial gastrocnemius compared with saline infusion and occurred without phosphatidylinositol 3-kinase activation. Glucose uptake was also assessed in vitro by use of the epitrochlearis muscle incubated either with AICAR (0.5 mM) or insulin (20 mU/ml) or both in the presence or absence of wortmannin (1.0 microM). AICAR and insulin increased muscle 2-DG uptake rates by approximately 2- and 2.7-fold, respectively, compared with basal rates. Combining AICAR and insulin led to a fully additive effect on muscle glucose transport activity. Wortmannin inhibited insulin-stimulated glucose uptake. However, neither wortmannin nor 8-(p-sulfophenyl)-theophylline (10 microM), an adenosine receptor antagonist, inhibited the AICAR-induced activation of glucose uptake. Electrical stimulation led to an about threefold increase in glucose uptake over basal rates, whereas no additive effect was found when AICAR and contractions were combined. In conclusion, the activation of AMPK by AICAR increases skeletal muscle glucose transport activity both in vivo and in vitro. This cellular pathway may play an important role in exercise-induced increase in glucose transport activity. (+info)
5' AMP-activated protein kinase activation causes GLUT4 translocation in skeletal muscle. (4/623)It has previously been reported that exercise causes an increase in glucose uptake in skeletal muscle and also an increase in 5' AMP-activated protein kinase (AMPK) activity. 5-Aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICA-riboside), an analog of adenosine, is taken up into cells and phosphorylated to form AICA-riboside monophosphate (ZMP), which can also activate AMPK. This study was designed to determine whether the increase in glucose uptake observed with AMPK activation by AICA-riboside is due to GLUT4 translocation from an intracellular location to the plasma membranes, similar to that seen in response to contraction. Rat hindlimbs were perfused with Krebs-Henseleit bicarbonate containing 4% bovine serum albumin, washed bovine erythrocytes, 8 mmol/l glucose, and +/-2 mmol/AICA-riboside or +/-60 nmol/l insulin. Perfusion medium containing AICA-riboside was found to significantly increase AMPK activity, glucose uptake, and GLUT4 translocation in skeletal muscle above basal levels. Insulin-perfused muscles showed significant increases in glucose uptake and GLUT4 translocation, but AMPK activation was not significantly changed from basal levels. These results provide evidence 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.

Translocation of myocardial GLUT-4 and increased glucose uptake through activation of AMPK by AICAR. (5/623)Insulin increases glucose uptake through the translocation of GLUT-4 via a pathway mediated by phosphatidylinositol 3-kinase (PI3K). In contrast, myocardial glucose uptake during ischemia and hypoxia is stimulated by the translocation of GLUT-4 to the surface of cardiac myocytes through a PI3K-independent pathway that has not been characterized. AMP-activated protein kinase (AMPK) activity is also increased by myocardial ischemia, and we examined whether AMPK stimulates glucose uptake and GLUT-4 translocation. In isolated rat ventricular papillary muscles, 5-aminoimidazole-4-carboxyamide-1-beta-D-ribofuranoside (AICAR), an activator of AMPK, as well as cyanide-induced chemical hypoxia and insulin, increased 2-[(3)H]deoxyglucose uptake two- to threefold. Wortmannin, a PI3K inhibitor, did not affect either the AICAR- or the cyanide-stimulated increase in deoxyglucose uptake but eliminated the insulin-stimulated increase in deoxyglucose uptake. Immunofluorescence studies demonstrated translocation of GLUT-4 to the myocyte sarcolemma in response to stimulation with AICAR, cyanide, or insulin. Preincubation of papillary muscles with the kinase inhibitor iodotubercidin or adenine 9-beta-D-arabinofuranoside (araA), a precursor of araATP (a competitive inhibitor of AMPK), decreased AICAR- and cyanide-stimulated glucose uptake but did not affect basal or insulin-stimulated glucose uptake. In vivo infusion of AICAR caused myocardial AMPK activation and GLUT-4 translocation in the rat. We conclude that AMPK activation increases cardiac muscle glucose uptake through translocation of GLUT-4 via a pathway that is independent of PI3K. These findings suggest that AMPK activation may be important in ischemia-induced translocation of GLUT-4 in the heart. (+info)
Improvement by 5-amino-4-imidazole carboxamide riboside of the contractile dysfunction that follows brief periods of ischemia through increases in ecto-5-nucleotidase activity and adenosine release in canine hearts. (6/623)5-Amino-4-imidazole carboxamide (AICA) riboside increases adenosine release in ischemic myocardium, suggesting that AICA riboside improves contractile dysfunction. In 49 open-chest dogs, contractile function assessed by fractional shortening (FS) was observed 3 h after the onset of reperfusion following 15 min of occlusion of the left anterior descending coronary artery. During reperfusion, the treatment with AICA riboside increased adenosine concentration in the coronary venous blood (536+/-44 vs. 281+/-21 pmol/ml at 3 min of reperfusion, p<0.001) and peak coronary hyperemic flow (367+/-13 vs. 300+/-21 ml/100 g per min, p<0.001) when compared with the untreated group. FS at 3h of reperfusion increased in the AICA riboside group (21.1+/-2.3 vs. 12.8+/-0.6% in the untreated group, p<0.001). AICA riboside increased myocardial ecto-5'-nucleotidase activity. Administration of adenosine also augmented coronary hyperemic flow and increased FS to the levels of the AICA riboside group. Either 8-phenyltheophylline (an antagonist of adenosine receptors) or alpha,beta-methylene-adenosine 5'-diphosphate (an inhibitor of ecto-5'-nucleotidase) completely abolished the increased coronary hyperemic flow and improvements of myocardial contractile function due to AICA riboside. Thus it was concluded that AICA riboside improves the contractile dysfunction that follows a brief period of ischemia via adenosine-dependent mechanisms. (+info)
Effect of methotrexate on blood purine and pyrimidine levels in patients with rheumatoid arthritis. (7/623)OBJECTIVE: The mechanism of anti-inflammatory effects of methotrexate (MTX) at low dose may relate to a decrease in availability of the purine precursor or it may depend on accumulation of 5-aminoimidazole-4-carboxamide (AICAR) and the anti-inflammatory nucleoside adenosine. The aim of this study was to evaluate the possible mechanism of action by analysis of changes in blood concentrations of purine and pyrimidine metabolites during MTX treatment. METHODS: Venous blood samples were collected from rheumatoid arthritis patients before and at different times for up to 7 days after the start of MTX treatment. Whole blood concentrations of adenosine, uridine, hypoxanthine, uric acid and erythrocyte nucleotides were measured by HPLC. RESULTS: The initial blood adenosine concentration was 0.073 +/- 0.013 microM and no differences were observed during MTX treatment. However, a decrease in uric acid concentration was observed from 205.5+/-13.5 to 160. 9+/-13.5 microM (P<0.05) within 24 h after MTX administration. The hypoxanthine concentration decreased in parallel with uric acid, while the uridine concentration decreased 48 h after MTX administration. No accumulation of AICAR-triphosphate (ZTP) was observed in the erythrocytes. CONCLUSIONS: MTX decreases circulating purine and pyrimidine concentrations, and their availability for DNA and RNA synthesis, which may affect immune cell proliferation and protein (cytokine) expression. The absence of adenosine concentration changes and lack of ZTP formation is evidence against an AICAR/adenosine mechanism, although localized adenosine concentration changes cannot be excluded.

Chronic activation of 5'-AMP-activated protein kinase increases GLUT-4, hexokinase, and glycogen in muscle. (8/623)This study was designed to determine whether chronic chemical activation of AMP-activated protein kinase (AMPK) would increase glucose transporter GLUT-4 and hexokinase in muscles similarly to periodic elevation of AMPK that accompanies endurance exercise training. The adenosine analog, 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), has previously been shown to be taken up by cells and phosphorylated to form a compound (5-aminoimidazole-4-carboxamide ribonucleotide) that mimics the effect of AMP on AMPK. A single injection of AICAR resulted in a marked increase in AMPK in epitrochlearis and gastrocnemius/plantaris muscles 60 min later. When rats were injected with AICAR (1 mg/g body wt) for 5 days in succession and were killed 1 day after the last injection, GLUT-4 was increased by 100% in epitrochlearis muscle and by 60% in gastrocnemius muscle in response to AICAR. Hexokinase was also increased approximately 2. 5-fold in the gastrocnemius/plantaris. Gastrocnemius glycogen content was twofold higher in AICAR-treated rats than in controls. Chronic chemical activation of AMPK, therefore, results in increases in GLUT-4 protein, hexokinase activity, and glycogen, similarly to those induced by endurance training. (+info)

Abstract In the present study, the effect of 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR) on long-chain fatty acid oxidation by hepatocytes isolated from suckled neonatal pig liver (a low ketogenic and lipogenic tissue) was tested. Incubation of hepatocytes with AICAR (0.5 mM) in the presence of 1 mM of carnitine and 10 mM of glucose for 1 hour at 37and#176;C had no significant effect on total [1-14C]-palmitate (0.5 mM) oxidation (14CO2 and 14C-Acid soluble products (ASP)). Consistent with the fatty acid oxidation, carnitine palmitoyltransferase I activity and inhibition of its activity by malonyl-CoA (10 and#956;M) assayed in cell homogenate also remained constant. However, addition of AICAR to the hepatocytes decreased 14CO2 production by 18% compared to control (p andlt; 0.06). The reduction of labeled carboxylic carbon accumulated in CO2 caused a significant difference in distribution of oxidative products between 14CO2 and 14C-ASP (p andlt; 0.03) compared with the control. It was ...
PGC-1α is required for AICAR induced expression of GLUT4 and mitochondrial proteins in mouse skeletal muscle
We tested the hypothesis that repeated activation of AMPK induces mitochondrial and glucose membrane transporter gene/protein expression via a peroxisome proliferator activated receptor Upsilon co-activator (PGC)-1alpha dependent mechanism. Whole body PGC-1alpha knockout (KO) and littermate wild type (WT) mice were given either a single or repeated subcutaneous injection of the AMPK activator AICAR or saline. Skeletal muscles were dissected either 1h or 4h after the single AICAR treatment or 24h after the last injection following the repeated AICAR treatment. Repeated AICAR treatment increased GLUT4, cytochrome c oxidase (COX)I and cytochrome (cyt) c protein expression ~10-40% relative to saline in white muscles of the WT mice, but not of the PGC-1alpha KO mice. In line, GLUT4 and cyt c mRNA content increased 30-60% 4h after a single AICAR injection relative to saline only in WT mice. One hour after a single AICAR treatment, phosphorylation of AMP-activated protein kinase (AMPK) and the ...
Enhancement of insulin-mediated rat muscle glucose uptake and microvascular perfusion by 5-aminoimidazole-4-carboxamide-1-beta...
BACKGROUND: Insulin-induced microvascular recruitment is important for optimal muscle glucose uptake. 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICAR, an activator of AMP-activated protein kinase), can also induce microvascular recruitment, at doses that do not acutely activate glucose transport in rat muscle. Whether low doses of AICAR can augment physiologic insulin action is unknown. In the present study we used the euglycemic hyperinsulinemic clamp to assess whether insulin action is augmented by low dose AICAR. METHODS: Anesthetized rats were studied during saline infusion or euglycemic insulin (3 mU/kg/min) clamp for 2 h in the absence or presence of AICAR for the last hour (5 mg bolus followed by 3.75 mg/kg/min). Muscle glucose uptake (Rg) was determined radioisotopically with (14)C-2-deoxyglucose and muscle microvascular perfusion by contrast-enhanced ultrasound with microbubbles. RESULTS: AICAR did not affect blood glucose, or lower leg Rg, although it significantly (p | 0.05)
AMP-Activated Protein Kinase Activation by AICAR Increases Both Muscle Fatty Acid and Glucose Uptake in White Muscle of Insulin...
The present study is the first demonstration that administration of AICAR to insulin-resistant HF rats simultaneously increases glucose and FA uptake into skeletal muscle in close association with activation of AMPK. These effects occurred preferentially in white muscle and were consistent with the previously described improvement of insulin sensitivity in white muscle 24 h after AICAR treatment (8). Contrary to our initial speculation, there was no higher FA uptake in red muscle to balance the lack of AICAR effect on glucose uptake in this muscle type.. It is known that fluxes of glucose and FA into muscle are increased from the circulation during exercise (1,23,24). Recent studies have revealed an important role of AMPK in exercise-induced changes in fuel metabolism (1,2). However, many other factors are also important metabolic regulators in contracting muscle (7), such as decreased energy storage (ATP and creatine phosphate content) (25), increases in metabolic rate, muscle blood flow, and ...

5-aminoimidazole-4-carboxamide-1-β-D-ribofuranoside (AICAR) is an established pharmacological activator of AMP-activated protein kinase (AMPK). Both, AICAR and AMPK were reported to attenuate inflammation. However, AICAR is known for many AMPK-independent effects, although the mechanisms remain incompletely understood. Here we report a potent suppression of lipopolysaccharide (LPS)-induced inflammatory gene expression by AICAR in primary human macrophages, which occurred independently of its conversion to AMPK-activating 5-aminoimidazole-4-carboxamide-1-β-D-ribofuranosyl monophosphate. Although AICAR did not interfere with activation of cytosolic signalling cascades and nuclear translocation of nuclear factor - κB (NFκB) by LPS, it prevented the recruitment of NFκB and RNA polymerase II to target gene promoters. AICAR also inhibited signal transducer and activator of transcription 3 (STAT3)-dependent induction of interleukin (IL) IL-6 and IL-10 targets, while leaving STAT6 and HIF1α-dependent gene

Ultraviolet (UV) radiation and reactive oxygen species (ROS) impair the physiological functions of retinal pigment epithelium (RPE) cells by inducing cell apoptosis, which is the main cause of age-related macular degeneration (AMD). The mechanism by which UV/ROS induces RPE cell death is not fully addressed. Here, we observed the activation of a ceramide-endoplasmic reticulum (ER) stress-AMP activated protein kinase (AMPK) signaling axis in UV and hydrogen peroxide (H2O2)-treated RPE cells. UV and H2O2 induced an early ceramide production, profound ER stress and AMPK activation. Pharmacological inhibitors against ER stress (salubrinal), ceramide production (fumonisin B1) and AMPK activation (compound C) suppressed UV- and H2O2-induced RPE cell apoptosis. Conversely, cell permeable short-chain C6 ceramide and AMPK activator AICAR (5-amino-1-β-D-ribofuranosyl-imidazole-4-carboxamide) mimicked UV and H2O2s effects and promoted RPE cell apoptosis. Together, these results suggest that UV/H2O2 activates the
The present study demonstrates an apparent insulin-sensitizing effect of the AMPK activator AICAR 24 h after its administration in the insulin-resistant HF rat. A major contributor to this was an improvement in insulin-mediated suppression of HGO. In addition, insulin action was enhanced in muscle, with a greater relative enhancement in white compared with red muscle. In both tissues, these effects were associated with a decrease in the concentration of malonyl CoA and in liver a decrease in the concentration of triglyceride. Although our investigation focused on AICAR effects in the insulin-resistant HF rat, follow-up studies demonstrated that at least some insulin-sensitizing effects after AICAR injection also occur in normal rats that were fed a standard diet, notably also with significant enhancement of insulin-stimulated glucose uptake in white muscle.. AMPK plays a crucial role in mediating glucose and lipid metabolism during exercise (2,26,28). A previous study from our laboratory showed ...
AMPK Causes Cell Cycle Arrest in LKB1-Deficient Cells via Activation of CAMKK2 | Molecular Cancer Research
Our results show that, even in LKB1-null tumor cells, activation of AMPK is sufficient for cell-cycle arrest, and necessary for the arrest induced by Ca2+-elevating agents. Inhibition of cell proliferation and G1 arrest in response to AMPK activation has been demonstrated previously in cells expressing LKB1 (12-14). However, those studies relied on the use of the pharmacologic activator 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), which can have AMP-independent off-target effects (42), or on overexpression of activated AMPK, which might also lead to nonphysiologic effects. Our results show that the G1 arrest (25) and consequent inhibition of proliferation (24) caused by the reexpression of LKB1 in LKB1-null tumor cells is mediated by AMPK and not by any of the AMPK-related kinases (ARK). We have previously shown that the ARKs that have detectable activity in HeLa cells, that is, SIK1, SIK2, SIK3, NUAK2, MARK1, MARK2/3, and MARK4, were (unlike AMPK) not activated in the cells by ...

Attention! In the May issue of Drug Testing and Analysis (Thevis. 2011), Mario Thevis and his colleagues from the Center for Preventive Doping Research - Institute of Biochemistry at the German Sport University in Cologne report that the powdered form of AICAR they had purchased from dubious Internet sources along with GW1516 another AMPK agonist and PPARδ modulator and a SARM (MK-2866), back in 2010, and which had passed customs mislabeled as containing amino acids and green tea extract did in fact contain the inosine monophosphate intermediate 5-Aminoimidazole-4-carboxamide ribotide. Yet, of the 100mg of white powder the scientists received, only 45% contained the active ingredient. In this context it is also noteworthy, that a) AICAR is not yet approved as a drug by any federal agency, I know of, so that your doctor could not even prescribe it at the moment and b) it is not even likely that it will ever be approved, because BigPharma wont be interested in a naturally occurring and thus ...
AICAR - ILQO PHARMA
60 caps X 5 mg. Each capsules contains 5mg. AICAR (chemical name: 5-Aminoimidazole-4-carboxamide ribonucleotide) is a peptide, which is an intermediate within the generation of inosine monophosphate and directly related to metabolic regulation. The most important mechanism that AICAR is known for is its ability to block enzymes both in intracellular and extracellular levels, which, in turn, allows for an accelerated stimulation of glucose uptake and increase protein kinases in skeletal muscle tissue. These two functions allow for more energy conversion, which helps burn fat and also sustain output in activity. This is what scientists and athletes/bodybuilders are interested in, but there are some amazing side effects.. Interestingly, AICAR has been shown to protect against ischemic injury. This type of injury is directly related to the restriction of blood to tissues, which can cause insufficient amounts of oxygen and glucose needed to keep the tissue alive. This can lead to thrombosis, ...

Abstract 19979: Rapid ERα-AMPK Signaling Stimulates Vasorelaxation via ERK-Mediated Pathway | Circulation
Background: 17-β-estradiol has been shown to play an important role in regulating vascular function and vasomotor tone. We have previously demonstrated sex differences in rapid estrogen receptor signaling during vascular relaxation. We recently observed that estrogen activates AMPK-activated protein kinase (AMPK), suggesting that AMPK is a likely mediator of estrogen receptor (ER) signaling in vasomotor function. AMPK has been reported to participate in vascular relaxation. Furthermore, our recent studies found that incubating vascular rings with 5-aminoimidazole-4-carboxamide (AICAR), an AMPK activator, results in greater vasorelaxation of female C57BL/6J mouse vessels when compared with male vessels. However, the precise mechanisms involving estrogen receptor signaling and AMPK in promoting vascular relaxation remain unknown.. Methods and Results: To elucidate a critical role of ERα-AMPK signaling and downstream targets involved in vascular relaxation, including the potential sex difference ...

The 5 adenosine monophosphate-activated protein kinase: Regulating th by Leonidas G. Karagounis and John Alan Hawley
The 5′ adenosine monophosphate-activated protein kinase (AMPK) is a heterotrimeric, evolutionary conserved enzyme which has emerged as a critical regulator of skeletal muscle cellular bioenergetics. AMPK is activated by both chemical (adipokines) and mechanical (stretch, contraction) stimuli leading to metabolic changes within muscle cells that include increased fatty acid oxidation, glucose uptake and glycolysis, as well as the stimulation and regulation of mitochondrial biogenesis. Collectively these acute responses and chronic adaptations act to reduce cellular disturbances, resulting in tighter metabolic control and maintenance of energy homeostasis. This brief review will describe the structure, function and activation of AMPK in skeletal muscle and how this ubiquitous molecule may be a plausible target for the treatment of several lifestyle-related metabolic disorders.

N2 - The AMP-activated protein kinase (AMPK) is a metabolic stress-sensing αβγ heterotrimer responsible for energy homeostasis. Pharmacological inhibition of AMPK is regarded as a therapeutic strategy in some disease settings including obesity and cancer; however, the broadly used direct AMPK inhibitor compound C suffers from poor selectivity. We have discovered a dihydroxyquinoline drug (MT47-100) with novel AMPK regulatory properties, being simultaneously a direct activator and inhibitor of AMPK complexes containing ...
Mitochondrial DNA deletions induce the adenosine monophosphate-activated protein kinase energy stress pathway and result in...
Mitochondrial DNA (mtDNA) deletions occur sporadically in zygotic and somatic tissues and reach their highest concentration in substantia nigra. Previously, we noted the increase of the adenosine monophosphate (AMP)-activated protein kinase (AMPK) transcript by microarray in multiple cells and tissues bearing deletions. In this work, we demonstrate that the induction of AMPK transcript is dependent on deletions by quantitative polymerase chain reaction, and also demonstrate a deficiency in adenosine triphosphate (ATP) synthesis in the same cells. Consistent with AMPK induction, its known targets SREBF1 (sterol regulatory element binding protein-1) and ATG12 were inhibited and induced, respectively. AMPK induction is known to decrease secretory processes in some cells, and the secretion of both osteoprotegerin (OPG) and fibronectin (FN) proteins to the extracellular space was significantly deficient. Deletions caused a defect in the adenosine diphosphate (ADP)-ribosylation factor-like 2 (ARL2) ...

A possible role for AMP-activated protein kinase in exercise-induced glucose utilization: insights from humans and transgenic...
Exercise-induced glucose uptake in skeletal muscle is mediated by an insulin-independent mechanism, but the actual signals to glucose transport in response to muscle contraction have not been identified. The 5´-AMP-activated protein kinase (AMPK) has emerged as a putative mediator of contraction-induced glucose transport, although no conclusive evidence has been provided so far. Recent experiments in AMPK transgenic mice suggest that glucose transport induced by 5-amino-4-imidazolecarboxamide riboside (AICAR) or hypoxia is mediated by AMPK. In contrast, contraction-induced glucose transport in rodent skeletal muscle induced by electrical stimulation in vitro or in situ is not influenced or is only partially reduced by abolishing both or one of the catalytic AMPK subunits. This is compatible with exercise studies done in humans, where no tight correlation is found between AMPK activity and glucose uptake during exercise. Taken together, these results question an essential role of AMPK in ...
AMP-activated protein kinase and hepatic genes involved in glucose metabolism | Biochemical Society Transactions
Mammalian AMP-activated protein kinase presents strong structural and functional similarities with the yeast sucrose non-fermenting 1 (Snf1) kinase involved in the derepression of glucose-repressed genes. It is now clearly established that AMP-activated protein kinase in the liver decreases glycolytic/lipogenic gene expression as well as genes involved in hepatic glucose production. This is achieved through a decreased transcriptional efficiency of transcription factors such as sterol-regulatory-element-binding protein-1c, carbohydrate-response-element-binding protein, hepatocyte nuclear factor 4α or forkhead-related protein. Clearly, the long-term consequences of AMP-activated protein kinase activation have to be taken into account if activators of this enzyme are to be designed as anti-diabetic drugs.. ...

A-769662 inhibits adipocyte glucose uptake in an AMPK-independent manner - Lunds universitet
Activation of AMP-activated protein kinase (AMPK) is considered a valid strategy for the treatment of type 2 diabetes. However, despite the importance of adipose tissue for whole-body energy homeostasis, the effect of AMPK activation in adipocytes has only been studied to a limited extent and mainly with the AMP-mimetic 5-aminoimidazole-4-carboxamide-1-b-d-ribofuranoside (AICAR), which has limited specificity. The aim of this study was to evaluate the effect of the allosteric AMPK activators A‑769662 and 991 on glucose uptake in adipocytes. For this purpose, primary rat or human adipocytes, and cultured 3T3-L1 adipocytes, were treated with either of the allosteric activators, or AICAR, and basal and insulin-stimulated glucose uptake was assessed. Additionally, the effect of AMPK activators on insulin-stimulated phosphorylation of Akt and Akt substrate of 160 kDa was assessed. Furthermore, primary adipocytes from ADaM site binding drug-resistant AMPKb1 S108A knock-in mice were employed to ...
Amino-4-Imidazolecarboxamide Ribotide Directly Inhibits Coenzyme A Biosynthesis in Salmonella enterica | Journal of Bacteriology
AICAR accumulates in a purH mutant and inhibits the conversion of AIR to HMP, a step catalyzed by the SAM radical protein ThiC (14). The ThiC reaction has been reconstituted in vitro and is not affected by AICAR, indicating the effect in vivo was indirect (26). The present study was initiated to determine the mechanism by which AICAR accumulation inhibits the conversion of AIR to HMP.. The ThiC reaction uses SAM as a cosubstrate and is sensitive to fluctuations in CoA levels in vivo (14, 23, 24, 50). Nutritional studies led to the hypothesis that one metabolic consequence of AICAR accumulation was decreased CoA levels. Metabolite pool measurements confirmed that strains that accumulated AICAR had ∼3-fold-lower total CoA levels than the wild type. Although this level of CoA reduction does not generate a thiamine requirement in an otherwise wild-type strain, conditions that reduce flux through the purine biosynthetic pathway (i.e., adenine in the medium) increase the CoA requirement for thiamine ...
An Aspirin a Day? | Science Signaling
The protein kinase AMPK (adenosine monophosphate-activated protein kinase) directly monitors cellular energy stores as reflected by changes in cellular concentrations of AMP, adenosine diphosphate (ADP), and adenosine triphosphate (ATP). Through phosphorylation of its targets, it helps to control metabolism, polarity, autophagy, and the restraint of cell proliferation. Activation of AMPK is also proposed to be beneficial for the treatment of diseases, including cancer and diabetes. Hawley et al. (see the Perspective by Shaw and Cantley) report that AMPK can be activated by high concentrations of salicylate, a compound derived from the very commonly used drug aspirin. In mice, salicylate promoted fatty acid and carbohydrate metabolism in an AMPK-dependent fashion.. S. A. Hawley, M. D. Fullerton, F. A. Ross, J. D. Schertzer, C. Chevtzoff, K. J. Walker, M. W.

Regular exercise can protect the heart against external stimuli, but the | FGFR signaling promotes the growth of triple negative
Regular exercise can protect the heart against external stimuli, but the mechanism is not well comprehended. sympathetic nervous system and the consequent launch of catecholamines, which stimulate the -adrenergic receptors in the heart, are very important. Isoproterenol (ISO), a nonselective -adrenergic receptor agonist, can robustly induce cardiac fibrosis in animal models. As well, transgenic mice with cardiac overexpressing -adrenergic receptors showed cardiac fibrosis . Exercise teaching offers been shown to reduce fibrosis and matrix metalloproteinase dysregulation in the heart of aged rats . However, the mechanism by which exercise teaching alleviates cardiac redesigning remains elusive. Adenosine monophosphate-activated protein kinase (AMPK) is an evolutionarily conserved serine/threonine protein kinase that is a expert regulator of energy status from your single-cell to whole-body levels . AMPK can be triggered by conditions that increase intracellular AMP such as exercise , ...

N2 - The AMP-activated protein kinase (AMPK), a sensor of cellular energy status found in all eukaryotes, responds to changes in intracellular adenosine nucleotide levels resulting from metabolic stresses. Here we describe crystal structures of a heterotrimeric regulatory core fragment from Schizosaccharomyces pombe AMPK in complex with ADP, ADP/AMP, ADP/ATP, and 5-aminoimidazole-4-carboxamide 1-β-D-ribofuranotide (AICAR phosphate, or ZMP), a well-characterized AMPK activator. Prior crystallographic studies had revealed a single site in the γ subunit that binds either ATP or AMP within Bateman domain B. Here we show that ZMP binds at this site, mimicking the binding of AMP. An analogous site in Bateman domain A selectively accommodates ADP, which binds in a distinct manner that also involves direct ligation to ...

Of interest were the observations that after cells had accumulated ZMP, and AICAR was removed or 5-iodotubercidin was added, the intracellular ZMP level rapidly decreased and the augmentation of folate transport was reversed. Hence, continued synthesis of ZMP is required to sustain intracellular ZMP levels and the augmentation of RFC-mediated transport. Neither AICAR itself nor ZTP within the cells resulted in augmentation of folate transport. The basis for the rapid decrease of intracellular ZMP under these conditions is due in part to the conversion of ZMP to ZTP and to export mediated by RFC. It is also possible that a component of the decrease in cell ZMP was due to rapid hydrolysis back to the base.. This interaction between ZMP and folates at the level of a common carrier is a classic exchange reaction in which the transmembrane gradient for one substrate drives the uphill transport of another. Most uphill systems for members of the SLC superfamily of solute transport carriers derive their ...

AMP-activated Protein Kinase (AMPK) Signaling (Homo sapiens) - WikiPathways
AMPK signaling pathway, a fuel sensor and regulator, promotes ATP-producing and inhibits ATP-consuming pathways in various tissues. AMPK is a heterotrimer composed of alpha-catalytic and beta and gamma-regulatory subunits. Humans and rodents have two alpha and beta and three gamma isoforms; some genes are subject to alternative splicing increasing the range of possible heterotrimer combinations. Cellular stresses that inhibit ATP production or increase its consumption change the AMP:ATP ratio and activate the pathway. AMPK activation by AMP is not completely understood; the current model states that binding of AMP to the gamma subunit leads to conformational changes that allosterically activate AMPK and render phosphorylated-Thr172 unavailable for inhibitory dephosphorylation. ATP antagonizes the effect of AMP; both AMP and ATP bind in a mutually exclusive manner to the Bateman (CBS) domains of the gamma subunit. The upstream kinase, known as Lkb1, is a complex of one catalytic and two ...

In cancer cells, the epithelial-mesenchymal transition (EMT) confers the ability to invade basement membranes and metastasize to distant sites, establishing it as an appealing target for therapeutic intervention. Here, we report a novel function of the master metabolic kinase AMPK in suppressing EMT by modulating the Akt-MDM2-Foxo3 signaling axis. This mechanistic link was supported by the effects of siRNA-mediated knockdown and pharmacological activation of AMPK on epithelial and mesenchymal markers in established breast and prostate cancer cells. Exposure of cells to OSU-53, a novel allosteric AMPK activator, as well as metformin and AICAR, was sufficient to reverse their mesenchymal phenotype. These effects were abrogated by AMPK silencing. Phenotypic changes were mediated by Foxo3a activation, insofar as silencing or overexpressing Foxo3a mimicked the effects of AMPK silencing or OSU-53 treatment on EMT, respectively. Mechanistically, Foxo3a activation led to the transactivation of the ...

The ratio between ATP and AMP is used as a way for a cell to sense how much energy is available and control the metabolic pathways that produce and consume ATP. The body attempts to maintain a specific ratio of AMP:ATP; when this ratio is out of balance, the cells adjust their metabolism accordingly. As the ratio increases either by increased levels of AMP or decreased levels of ATP, the body is signaled to produced more ATP. The AMP:ATP ratio is primarily regulated by an enzyme known as AMP-activated protein kinase (AMPK). When activated, AMPK sets in motion a series of events which switch cells from active ATP consumption to ATP production ...

During 2 years, we enrolled 25 patients diagnosed with typewriter tinnitus and evaluated the types of AICA loops in the IAC and CPA and the types of neurovascular contact by using 3T 3D T2-VISTA imaging in 15 patients. When we compared the symptomatic sides of patients with typewriter tinnitus (group 1) with the asymptomatic sides of those with typewriter tinnitus (group 2) and healthy controls (group 3), the difference was not statistically significant (Table). However, considering that in a previous study, type II and type III AICA loops were observed in 38.0% of 332 patients with ipsilateral auditory symptoms,13 our results, which demonstrated that 56.3% of group 1 and 18.8% of group 3 had type II and III AICA loops, showed a definite tendency toward type II and III AICA loops on the symptomatic sides of subjects with typewriter tinnitus.
