These pathways are involved in major physiological processes as well as in numerous pathological conditions. Here, involvement of the mTOR pathway in epilepsy will be reviewed by presenting; an overview of the pathway, a brief description of key signaling molecules, a summary of independent reports and possible implications of abnormalities of those molecules in epilepsy, a discussion of the lack of experimental data, and questions raised for the understanding its epileptogenic mechanism.
Hypothalamic mTOR signaling regulates food intake. The mammalian Target of Rapamycin mTOR protein is a serine-threonine kinase that regulates cell-cycle progression and growth by sensing changes in energy status. We demonstrated that mTOR signaling plays a role in the brain mechanisms that respond to nutrient availability, regulating energy balance.
In the rat, mTOR signaling is controlled by energy status in specific regions of the hypothalamus and colocalizes with neuropeptide Y and proopiomelanocortin neurons in the arcuate nucleus. Central administration of leucine increases hypothalamic mTOR signaling and decreases food intake and body weight. The hormone leptin increases hypothalamic mTOR activity, and the inhibition of mTOR signaling blunts leptin's anorectic effect.
Thus, mTOR is a cellular fuel sensor whose hypothalamic activity is directly tied to the regulation of energy intake. Growing knowledge of the mTOR signaling network. The kinase mTOR mechanistic target of rapamycin integrates diverse environmental signals and translates these cues into appropriate cellular responses. While significantly less well understood than mTORC1, mTORC2 responds to growth factors and controls cell metabolism, cell survival, and the organization of the actin cytoskeleton.
Consequently, aberrant mTOR signaling contributes to myriad disease states, and physicians employ mTORC1 inhibitors rapamycin and analogs for several pathological conditions. Here we review our growing knowledge of cellular mTOR regulation by diverse upstream signals e.
We will cover major cellular functions controlled by mTORC1 broadly. While significant advances have been made in the last decade regarding the regulation and function of mTOR within complex cell signaling networks, many important findings remain to be discovered. All rights reserved.
A comprehensive map of the mTOR signaling network. The mammalian target of rapamycin mTOR is a central regulator of cell growth and proliferation. Using CellDesigner, a modeling support software for graphical notation, we present herein a comprehensive map of the mTOR signaling network, which includes species connected by reactions.
The map complies with both the systems biology markup language SBML and graphical notation SBGN for computational analysis and graphical representation, respectively. As captured in the mTOR map, we review and discuss our current understanding of the mTOR signaling network and highlight the impact of mTOR feedback and crosstalk regulations on drug-based cancer therapy. This map is available on the Payao platform, a Web 2.
Thus, this comprehensive map of the mTOR network will serve as a tool to facilitate systems-level study of up-to-date mTOR network components and signaling events toward the discovery of novel regulatory processes and therapeutic strategies for cancer. Intracellular signaling of mTOR complexes is involved in many of physiological functions including cell survival, proliferation and differentiation through the regulation of protein synthesis in multiple cell types.
During brain development, mTOR-mediated signaling pathway plays a crucial role in the process of neuronal and glial differentiation and the maintenance of the stemness of neural stem cells. The abnormalities in the activity of mTOR and its downstream signaling molecules in neural stem cells result in severe defects of brain developmental processes causing a significant number of brain disorders, such as pediatric brain tumors, autism, seizure, learning disability and mental retardation.
Understanding the implication of mTOR activity in neural stem cells would be able to provide an important clue in the development of future brain developmental disorder therapies. Overnutrition, mTOR signaling , and cardiovascular diseases. The prevalence of obesity and associated medical disorders has increased dramatically in the United States and throughout much of the world in the past decade. Obesity, induced by excess intake of carbohydrates and fats, is a major cause of Type 2 diabetes, hypertension, and the cardiorenal metabolic syndrome.
There is emerging evidence that excessive nutrient intake promotes signaling through the mammalian target of rapamycin mTOR , which, in turn, may lead to alterations of cellular metabolic signaling leading to insulin resistance and obesity-related diseases, such as diabetes, cardiovascular and kidney disease, as well as cancer.
While the pivotal role of mTOR signaling in regulating metabolic stress, autophagy, and adaptive immune responses has received increasing attention, there remain many gaps in our knowledge regarding this important nutrient sensor. For example, the precise cellular signaling mechanisms linking excessive nutrient intake and enhanced mTOR signaling with increased cardiovascular and kidney disease, as well as cancer, are not well understood.
In this review, we focus on the effects that the interaction between excess intake of nutrients and enhanced mTOR signaling have on the promotion of obesity-associated diseases and potential therapeutic strategies involving targeting mTOR signaling. Cancer is a complex disease and a leading cause of death worldwide. Extensive research over decades has led to the development of therapies that target cancer-specific signaling pathways.
However, the clinical benefits of such drugs are at best transient due to tumors displaying intrinsic or adaptive resistance. The underlying compensatory pathways that allow cancer cells to circumvent a drug blockade are poorly understood. We review here recent studies suggesting that mammalian TOR mTOR signaling is a major compensatory pathway conferring resistance to many cancer drugs.
These findings suggest that mTOR signaling should be monitored routinely in tumors and that an mTOR inhibitor should be considered as a co-therapy. Dysregulation of mTOR signaling in fragile X syndrome. Fragile X syndrome, the most common form of inherited mental retardation and leading genetic cause of autism, is caused by transcriptional silencing of the Fmr1 gene.
The Fmr1 knock-out mouse, a model of fragile X syndrome, exhibits cognitive deficits and exaggerated metabotropic glutamate receptor mGluR -dependent long-term depression at CA1 synapses. However, the molecular mechanisms that link loss of function of FMRP to aberrant synaptic plasticity remain unclear. The mammalian target of rapamycin mTOR signaling cascade controls initiation of cap-dependent translation and is under control of mGluRs.
Here we show that mTOR phosphorylation and activity are elevated in hippocampus of juvenile Fmr1 knock-out mice by four functional readouts: 1 association of mTOR with regulatory associated protein of mTOR ; 2 mTOR kinase activity; 3 phosphorylation of mTOR downstream targets S6 kinase and 4E-binding protein; and 4 formation of eukaryotic initiation factor complex 4F, a critical first step in cap-dependent translation.
Elevated mTOR signaling may provide a functional link between overactivation of group I mGluRs and aberrant synaptic plasticity in the fragile X mouse, mechanisms relevant to impaired cognition in fragile X syndrome. Follistatin-mediated skeletal muscle hypertrophy is regulated by Smad3 and mTOR independently of myostatin. Winbanks, Catherine E. Follistatin is essential for skeletal muscle development and growth, but the intracellular signaling networks that regulate follistatin-mediated effects are not well defined.
We show here that the administration of an adeno-associated viral vector expressing follistatinaa rAAV6:Fst markedly increased muscle mass and force-producing capacity concomitant with increased protein synthesis and mammalian target of rapamycin mTOR activation.
Furthermore, we identify Smad3 as the critical intracellular link that mediates the effects of follistatin on mTOR signaling. Importantly, the regulation of Smad3- and mTOR-dependent events by follistatin occurred independently of overexpression or knockout of myostatin, a key repressor of muscle development that can regulate Smad3 and mTOR signaling and that is itself inhibited by follistatin. The role of mTOR signaling in the regulation of protein synthesis and muscle mass during immobilization in mice.
It has been well recognized that skeletal muscle mass is regulated by mechanically induced changes in protein synthesis, and that signaling by mTOR is necessary for an increase in protein synthesis and the hypertrophy that occurs in response to increased mechanical loading. However, the role of mTOR signaling in the regulation of protein synthesis and muscle mass during decreased mechanical loading remains largely undefined.
In order to define the role of mTOR signaling , we employed a mouse model of hindlimb immobilization along with pharmacological, mechanical and genetic means to modulate mTOR signaling. The results first showed that immobilization induced a decrease in the global rates of protein synthesis and muscle mass.
Interestingly, immobilization also induced an increase in mTOR signaling , eIF4F complex formation and cap-dependent translation. Blocking mTOR signaling during immobilization with rapamycin not only impaired the increase in eIF4F complex formation, but also augmented the decreases in global protein synthesis and muscle mass.
On the other hand, stimulating immobilized muscles with isometric contractions enhanced mTOR signaling and rescued the immobilization-induced decrease in global protein synthesis through a rapamycin-sensitive mechanism that was independent of ribosome biogenesis.
Unexpectedly, the effects of isometric contractions were also independent of eIF4F complex formation. Similar to isometric contractions, overexpression of Rheb in immobilized muscles enhanced mTOR signaling , cap-dependent translation and global protein synthesis, and prevented the reduction in fiber size. Therefore, we conclude that the activation of mTOR signaling is both necessary and sufficient to alleviate the decreases in protein synthesis and muscle mass that occur during immobilization.
Furthermore, these results indicate. In the case of epilepsy, it has been observed alteration in the pathophysiological process of the same. However, they have not described all the mechanisms of these signaling pathways that could open the opportunity to new research and therapeutic strategies. To review existing partnerships between intracellular signaling pathways AKT and mTOR in the pathophysiology of epilepsy.
Epilepsy is a disease with a high epidemiological impact globally, so it is widely investigated regarding the pathophysiological components thereof. In that search they have been involved different intracellular signaling pathways in neurons, as determinants epileptogenic.
Advances in this field have even allowed the successful implementation of new therapeutic strategies and to open the way to new research in the field. The use of mTOR inhibitors, has emerged in recent years as effective in treating this disease entity alternative however is clear the necessity of continue the research for new drug therapies. The role of mTOR signaling in Alzheimer disease.
The buildup of Abeta and tau is believed to directly cause or contribute to the progressive cognitive deficits characteristic of Alzheimer disease. However, the molecular pathways linking Abeta and tau accumulation to learning and memory deficits remain elusive.
There is growing evidence that soluble forms of Abeta and tau can obstruct learning and memory by interfering with several signaling cascades. In this review, I will present data showing that the mammalian target of rapamycin mTOR may play a role in Abeta and tau induced neurodegeneration. Regulation and function of mTOR signalling in T cell fate decision. The evolutionary conserved kinase mTOR couples cell growth and metabolism to environmental inputs in eukaryotes.
T cells depend on mTOR signalling to integrate immune signals and metabolic cues for their proper maintenance and activation. Under steady-state conditions, mTOR is actively controlled by multiple inhibitory mechanisms, and this enforces normal T cell homeostasis. This phenomenon is distinguished by S6 and 4E-BP1 activity in response to nutrient stimulation. The mammalian target of rapamycin mTOR is a central regulator of gene expression, translation and various metabolic processes.
Multiple extracellular growth factors and intracellular energy status molecular signals as well as a variety of stressors are integrated into the mTOR pathway. Viral infection is a significant stress that can activate, reduce or even suppress the mTOR signaling pathway. Consequently, viruses have evolved a plethora of different mechanisms to attack and co-opt the mTOR pathway in order to make the host cell a hospitable environment for replication.
A more comprehensive knowledge of different viral interactions may provide fruitful targets for new antiviral drugs. The mTOR signaling network functions as a pivotal regulatory cascade during the development of the cerebral cortex. Investigation of mTOR signaling in these disorders provides for the first time exciting future avenues for assessment of biomarkers, patient stratification and prognostic measures as well as the opportunity for targeted therapy to regulate mTOR activity across all age groups.
As we learn more about mTOR and its activity in the developing brain, many challenges will arise that must be overcome before widespread clinical therapeutics can be implemented. Published by Elsevier Ltd. This review outlines the current understanding of mTOR regulation in insulin signaling in the context of whole body metabolism. The mTOR signalling cascade: paving new roads to cure neurological disease.
Defining the multiple roles of the mechanistic formerly 'mammalian' target of rapamycin mTOR signalling pathway in neurological diseases has been an exciting and rapidly evolving story of bench-to-bedside translational research that has spanned gene mutation discovery, functional experimental validation of mutations, pharmacological pathway manipulation, and clinical trials.
Alterations in the dual contributions of mTOR - regulation of cell growth and proliferation, as well as autophagy and cell death - have been found in developmental brain malformations, epilepsy, autism and intellectual disability, hypoxic-ischaemic and traumatic brain injuries, brain tumours, and neurodegenerative disorders.
In line with the positioning of mTOR as a pivotal cell signalling node, altered mTOR activation has been associated with a group of phenotypically diverse neurological disorders. To understand how altered mTOR signalling leads to such divergent phenotypes, we need insight into the differential effects of enhanced or diminished mTOR activation, the developmental context of these changes, and the cell type affected by altered signalling. A particularly exciting feature of the tale of mTOR discovery is that pharmacological mTOR inhibitors have shown clinical benefits in some neurological disorders, such as tuberous sclerosis complex, and are being considered for clinical trials in epilepsy, autism, dementia, traumatic brain injury, and stroke.
High-risk neuroblastoma often develops resistance to high-dose chemotherapy. The mTOR signaling cascade is frequently deregulated in human cancers and targeting mTOR signaling sensitizes many cancer types to chemotherapy. Here, using a panel of neuroblastoma cell lines, we found that the mTOR inhibitor INK showed inhibitory effects on both anchorage-dependent and independent growth of neuroblastoma cells and significantly enhanced the cytotoxic effects of doxorubicin Dox on these cell lines.
Using an orthotopic neuroblastoma mouse model, we found that INK significantly inhibited tumor growth in vivo. In conclusion, we have shown that INKmediated mTOR inhibition possessed substantial antitumor activity and could significantly increase the sensitivity of neuroblastoma cells to Doxorubicin therapy.
Taken together, our results indicate that using INK can provide additional efficacy to current chemotherapeutic regimens and represent a new paradigm in restoring drug sensitivity in neuroblastoma. The mammalian target of rapamycin mTOR kinase plays an important role in regulating cell growth and cell cycle progression in response to cellular signals.
It is a key regulator of cell proliferation and many upstream activators and downstream effectors of mTOR are known to be deregulated in various types of cancers. Since the mTOR signalling pathway is commonly activated in human cancers, many researchers are actively developing inhibitors that target key components in the pathway and some of these drugs are already on the market. Numerous preclinical investigations have also suggested that some herbs and natural phytochemicals, such as curcumin, resveratrol, timosaponin III, gallic acid, diosgenin, pomegranate, epigallocatechin gallate EGCC , genistein and 3,3'-diindolylmethane inhibit the mTOR pathway either directly or indirectly.
Some of these natural compounds are also in the clinical trial stage. In this review, the potential anti-cancer and chemopreventive activities and the current status of clinical trials of these phytochemicals are discussed. Mammalian target of rapamycin mTor plays multiple role in central nervous system and is involved in regulation of cell viability, differentiation, transcription, translation, protein degradation, actin cytoskeletal organization and autophagy.
Recent experimental and clinical studies reveal that disturbances of mTOR signaling are involved in the pathogenesis of autism spectrum disorders ASD. This article reviews current data on the alteration in the mTOR transduction cascade, which may contribute to common neurobehavioral disorders typical for ASD.
Moreover, the results of the latest experimental studies on the potential of mTOR inhibitors for the treatment of ASD are reviewed. Mechanistic insights into the role of mTOR signaling in neuronal differentiation. Temporal control of neuronal differentiation is critical to produce a complete and fully functional nervous system. Loss of the precise temporal control of neuronal cell fate can lead to defects in cognitive development and to disorders such as epilepsy and autism.
However, the mechanism by which mTOR regulates neurogenesis is poorly understood. In constrast to other functions of the pathway, 'neurogenic mTOR pathway factors' have not previously been identified. We have very recently used Drosophila as a model system to identify the gene unkempt as the first component of the mTOR pathway regulating neuronal differentiation. Our study demonstrates that specific adaptor proteins exist that channel mTOR signaling toward the regulation of neuronal cell fate.
In this Commentary we discuss the role of mTOR signaling in neurogenesis and the significance of these findings in advancing our understanding of the mechanism by which mTOR signaling controls neuronal differentiation. Mammalian target of rapamycin mTOR is a protein kinase involved in translation control and long-lasting synaptic plasticity.
Although the majority of evidence linking mTOR function to synaptic plasticity comes from studies utilizing rapamycin, studies in genetically modified mice also suggest that mTOR couples receptors to the translation machinery for establishing long-lasting synaptic changes that are the basis for higher order brain function, including long-term memory.
Finally, perturbation of the mTOR signaling cascade appears to be a common pathophysiological feature of human neurological disorders, including mental retardation syndromes and autism spectrum disorders. Although majority of evidence linking mTOR function to synaptic plasticity comes from studies utilizing rapamycin, studies in genetically-modified mice also suggest that mTOR couples receptors to the translation machinery for establishing long-lasting synaptic changes that are the basis for higher order brain function, including long-term memory.
Mammalian target of rapamycin mTOR signaling is required for a late-stage fusion process during skeletal myotube maturation. Skeletal myogenesis is a well orchestrated cascade of events regulated by multiple signaling pathways, one of which is recently characterized by its sensitivity to the bacterial macrolide rapamycin. Previously we reported that the mammalian target of rapamycin mTOR regulates the initiation of the differentiation program in mouse C2C12 myoblasts by controlling the expression of insulin-like growth factor-II in a kinase- independent manner.
Here we provide experimental evidence suggesting that a different mode of mTOR signaling regulates skeletal myogenesis at a later stage. In the absence of endogenous mTOR function in C2C12 cells treated with rapamycin, a kinase-inactive mTOR fully supports myogenin expression, but causes a delay in contractile protein expression.
Myoblasts fuse to form nascent myotubes in the absence of kinase-active mTOR , whereas the formation of mature myotubes by further fusion requires the catalytic activity of mTOR. Therefore, the two stages of myocyte fusion are molecularly separable at the level of mTOR signaling.
In addition, our data suggest that a factor secreted into the culture medium is responsible for mediating the function of mTOR in regulating the late-stage fusion leading to mature myotubes. Furthermore, taking advantage of the unique features of cells stably expressing a mutant mTOR , we have performed cDNA microarray analysis to compare global gene expression profiles between mature and nascent myotubes, the results of which have implicated classes of genes and revealed candidate regulators in myotube maturation or functions of mature myotubes.
The role of mTOR signalling in neurogenesis, insights from tuberous sclerosis complex. Understanding the development and function of the nervous system is one of the foremost aims of current biomedical research. The nervous system is generated during a relatively short period of intense neurogenesis that is orchestrated by a number of key molecular signalling pathways. Even subtle defects in the activity of these molecules can have serious repercussions resulting in neurological, neurodevelopmental and neurocognitive problems including epilepsy, intellectual disability and autism.
Tuberous sclerosis complex TSC is a monogenic disease characterised by these problems and by the formation of benign tumours in multiple organs, including the brain. A desire to understand the neurological manifestations of TSC has stimulated research into the role of the mTOR pathway in neurogenesis.
In this review we describe TSC neurobiology and how the use of animal model systems has provided insights into the roles of mTOR signalling in neuronal differentiation and migration. Recent progress in this field has identified novel mTOR pathway components regulating neuronal differentiation. The roles of mTOR signalling and aberrant neurogenesis in epilepsy are also discussed.
Continuing efforts to understand mTOR neurobiology will help to identify new therapeutic targets for TSC and other neurological diseases. Modulation of mTOR signaling as a strategy for the treatment of Pompe disease. Mechanistic target of rapamycin mTOR coordinates biosynthetic and catabolic processes in response to multiple extracellular and intracellular signals including growth factors and nutrients.
In this study, we have examined the involvement of the mTOR pathway in the pathophysiology of a severe muscle wasting condition, Pompe disease, caused by excessive accumulation of lysosomal glycogen. Here, we report the dysregulation of mTOR signaling in the diseased muscle cells, and we focus on potential sites for therapeutic intervention.
Reactivation of mTOR in the whole muscle of Pompe mice by TSC knockdown resulted in the reversal of atrophy and a striking removal of autophagic buildup. Of particular interest, we found that the aberrant mTOR signaling can be reversed by arginine. This finding can be translated into the clinic and may become a paradigm for targeted therapy in lysosomal, metabolic, and neuromuscular diseases.
Published under the terms of the CC BY 4. Balanced control of neural progenitor maintenance and neuron production is crucial in establishing functional neural circuits during brain development, and abnormalities in this process are implicated in many neurological diseases. However, the regulatory mechanisms of neural progenitor homeostasis remain poorly understood.
Here, we show that mammalian target of rapamycin mTOR is required for maintaining neural progenitor pools and plays a key role in mediating glycogen synthase kinase 3 GSK3 signaling during brain development. First, we generated and characterized conditional mutant mice exhibiting deletion of mTOR in neural progenitors and neurons in the developing brain using Nestin-cre and Nex-cre lines, respectively. The elimination of mTOR resulted in abnormal cell cycle progression of neural progenitors in the developing brain and thereby disruption of progenitor self-renewal.
Accordingly, production of intermediate progenitors and postmitotic neurons were markedly suppressed. Next, we discovered that GSK3, a master regulator of neural progenitors, interacts with mTOR and controls its activity in cortical progenitors.
Finally, we found that inactivation of mTOR activity suppresses the abnormal proliferation of neural progenitors induced by GSK3 deletion. Our findings reveal that the interaction between mTOR and GSK3 signaling plays an essential role in dynamic homeostasis of neural progenitors during brain development.
Regulation of autophagy by amino acids and MTOR -dependent signal transduction. Amino acids not only participate in intermediary metabolism but also stimulate insulin-mechanistic target of rapamycin MTOR -mediated signal transduction which controls the major metabolic pathways. Among these is the pathway of autophagy which takes care of the degradation of long-lived proteins and of the elimination of damaged or functionally redundant organelles.
Proper functioning of this process is essential for cell survival. Dysregulation of autophagy has been implicated in the etiology of several pathologies. The history of the studies on the interrelationship between amino acids, MTOR signaling and autophagy is the subject of this review. The mechanisms responsible for the stimulation of MTOR -mediated signaling , and the inhibition of autophagy, by amino acids have been studied intensively in the past but are still not completely clarified.
Recent developments in this field are discussed. We conclude by highlighting a few salient questions and future perspectives regarding mTOR in B lineage cells. Novalic, Zlata; van der Wal, Annemieke M. Inhibition of the mammalian target of rapamycin mTOR shows beneficial effects in animal models of polycystic kidney disease PKD ; however, two clinical trials in patients with autosomal dominant PKD failed to demonstrate a short-term benefit in either the early or progressive stages of disease.
The stage of disease during treatment and the dose of mTOR inhibitors may account for these differing results. When initiated at early but not late stages of disease, high-dose treatment strongly reduced mTOR signaling in renal tissues, inhibited cystogenesis, accelerated cyst regression, and abrogated fibrosis and the infiltration of immune cells. In contrast, low-dose treatment did not significantly reduce renal cystic disease.
Taken together, these data suggest that long-term treatment with conventional doses of sirolimus is insufficient to inhibit mTOR activity in renal cystic tissue. Mechanisms to increase bioavailability or to target mTOR inhibitors more specifically to kidneys, alone or in combination with other compounds, may improve the potential for these therapies in PKD. Ursolic acid UA , a pentacyclic triterpenoid widely found in medicinal herbs and fruits, has been reported to possess a wide range of beneficial properties including anti-hyperglycemia, anti-obesity, and anti-cancer.
However, the molecular mechanisms underlying the action of UA remain largely unknown. Taken together, our study identifies UA as a direct negative regulator of the mTORC1 signaling pathway and suggests a novel mechanism by which UA exerts its beneficial function. Cardamonin has previously demonstrated that it had an antiproliferative effect on vascular smooth muscle cells by inhibiting the activity of mammalian target of rapamycin mTOR. The antiproliferative effect and the possible mechanism of combining with mTOR of cardamonin were investigated on A cells.
Cell proliferation, cell cycle and apoptosis were measured by methyl thiazolyl tetrazolium MTT and flow cytometry, respectively. Treated with cardamonin, the proliferation of A cells was inhibited. Meanwhile, cell cycle was blocked and DNA synthesis was decreased whereas cell apoptosis was promoted, and the activation of mTOR and p70S6K was decreased by cardamonin. Rapamycin had a similar degree of effect on antiproliferation of both transfected cells.
Both rapamycin and cardamonin decreased the phosphorylation of mTOR and p70S6K in two kinds of transfected cells. Cardamonin inhibited proliferation and induced apoptosis of A cells via mTOR. High-frequency electrical stimulation reveals a p mTOR signaling module correlated with force-time integral. High-frequency electrical stimulation HFES leads to muscle hypertrophy, and attention has been drawn to the high forces involved. However, both mechanical and metabolic stresses occur simultaneously, and both stimuli influence signaling cascades related to protein synthesis.
This study aimed to identify the immediate signaling correlates of contraction-induced force and metabolic stresses under the hypothesis that HFES induces growth-related signaling through mechanical stimulation. Force-time integral FTI signaling in mouse tibialis anterior muscle was examined by separately manipulating the time of contraction to emphasize the metabolic aspect or the force of contraction to emphasize the mechanical aspect.
The consistent link among p38, mTOR and FTI suggests that they form a connected signaling module sensitive to the mechanical aspects of FTI, separate from markers of metabolic load. Bidirectional manipulation of mTOR signaling disrupts socially mediated vocal learning in juvenile songbirds. Early life experiences can have long-lasting behavioral consequences because they are encoded when the brain is most malleable.
The mechanistic target of rapamycin mTOR signaling cascade modulates experience-dependent synaptic plasticity, among other processes. It is among the most commonly implicated factors in neurodevelopmental autism spectrum disorders ASD , characterized, in part, by distinct social and communication phenotypes. Here, we investigated mTOR in juvenile zebra finch songbirds. Much as children learn language, young male zebra finches need to interact socially with an adult tutor to learn a meaningful song.
The memory of the tutor's song structure guides the juvenile's own song, which it uses to communicate for the rest of its life. We hypothesized that mTOR is required for juveniles to learn song. To this end, we first discovered that hearing song activates mTOR signaling in a brain area required for tutor song memorization in males old enough to copy song but not in younger males or females, who cannot sing. We then showed that both inhibition and constitutive activation of mTOR during tutor experiences significantly diminished tutor song copying.
Finally, we found that constitutive mTOR activation lowered a behavioral measure of the juvenile's social engagement during tutor experiences, mirroring the relationship in humans. These studies therefore advance understanding about the effects of experience in the context of neurodevelopmental disorders and typical neural development.
A complex mTOR response in habituation paradigms for a social signal in adult songbirds. Nonassociative learning is considered simple because it depends on presentation of a single stimulus, but it likely reflects complex molecular signaling. To advance understanding of the molecular mechanisms of one form of nonassociative learning, habituation, for ethologically relevant signals we examined song recognition learning in adult zebra finches. These colonial songbirds learn the unique song of individuals, which helps establish and maintain mate and other social bonds, and informs appropriate behavioral interactions with specific birds.
We leveraged prior work demonstrating behavioral habituation for individual songs, and extended the molecular framework correlated with this behavior by investigating the mechanistic Target of Rapamycin mTOR signaling cascade. To begin probing for a possible role for mTOR in song recognition learning, we used a combination of song playback paradigms and bidirectional dysregulation of mTORC1 activation.
We found that mTOR demonstrates the molecular signatures of a habituation mechanism, and that its manipulation reveals the complexity of processes that may be invoked during nonassociative learning. These results thus expand the molecular targets for habituation studies and raise new questions about neural processing of complex natural signals. Several studies previously showed that glucose metabolism dysregulations associated with obesity, diabetes or cancer correlated with an increase of OGT expression and global O-GlcNAcylation levels.
Moreover, these diseases present an increased activation of the nutrient sensing mammalian target of rapamycin mTOR pathway. In this context, we studied the cross-talk between these two metabolic sensors in vivo in obese mice predisposed to diabetes and in vitro in normal and colon cancer cells. Thus, a crosstalk exists between O-GlcNAcylation and mTOR signaling in contexts of metabolism dysregulation associated to obesity or cancer.
Glomerular diseases are commonly characterized by podocyte injury including apoptosis, actin cytoskeleton rearrangement and detachment. However, the strategies for preventing podocyte damage remain insufficient. Recently autophagy has been regarded as a vital cytoprotective mechanism for keeping podocyte homeostasis. Thus, it is reasonable to utilize this mechanism to attenuate podocyte injury.
Trehalose, a natural disaccharide, is an mTOR independent autophagy inducer. It is unclear whether trehalose alleviates podocyte injury. Therefore, we investigated the efficacy of trehalose in puromycin aminonucleoside PAN -treated podocytes which mimic cell damage in minimal change nephrotic syndrome in vitro.
Human conditional immortalized podocytes were treated with trehalose with or without PAN. Podocyte apoptosis and necrosis were evaluated by flow cytometry and by measuring lactate dehydrogenase activity respectively. We also performed migration assay to examine podocyte recovery.
It was shown that trehalose induced podocyte autophagy in an mTOR independent manner and without reactive oxygen species involvement. Podocyte apoptosis significantly decreased after trehalose treatment, while the inhibition of trehalose-induced autophagy abolished its protective effect. Additionally, the disrupted actin cytoskeleton of podocytes was partially reversed by trehalose, accompanying with less lamellipodias and diminished motility. These results suggested that trehalose induced autophagy in human podocytes and showed cytoprotective effects in PAN-treated podocytes.
Accumulation of advanced glycation end products AGEs in articular cartilage is thought to represent a major risk factor for osteoarthritis development. Cell viability was measured after human chondrocytes were treated with different concentrations of AGEs with or without the PPARG inhibitor, T, or agonist, pioglitazone. The agonist, pioglitazone, was shown to protect cell autophagy in a dose-dependent manner. Cortisol inhibits mTOR signaling in avascular necrosis of the femoral head. ANFH is a major health problem, to which long lasting and definitive treatments are lacking.
Decreased mTOR signaling in response to GR stimulation leading to downregulated HIF pathway as well as increased apoptosis could be the pathophysiology. Hypothalamic roles of mTOR complex I: Integration of nutrient and hormone signals to regulate energy homeostasis. Mammalian or mechanistic target of rapamycin mTOR senses nutrient, energy, and hormone signals to regulate metabolism and energy homeostasis. Dysembryoplastic neuroepithelial tumors DNTs are epilepsy-associated glioneuronal neoplasms which have not been analyzed extensively in this respect.
Sixty-four DNTs were identified, accounting for Duration of seizures ranged from 1 to 22 years. Interestingly, p-S6 positivity was also seen in adjacent dysplastic cortex. All patients that underwent incomplete resection had Engel grade II-III outcomes p mTOR and MAPK pathways suggests a role for altered signalling in DNT pathogenesis, and will pave the way for development of targeted therapies, particularly relevant for patients having persistent seizures after incomplete resection.
Targeting of hyperactivated mTOR signaling in high-risk acute lymphoblastic leukemia in a pre-clinical model. By current biomarkers, the majority of relapse patients is initially not identified indicating the need for prognostic and therapeutic targets reflecting leukemia biology. Thus, the TTLshort phenotype is functionally characterized by hyperactivated mTOR signaling and can effectively be targeted ex vivo and in vivo providing a novel therapeutic strategy for high-risk ALL.
Defects in rat sarcoma viral oncogene homolog RAS -extracellular signal regulated kinase ERK and phosphatidylinositol 3-kinase PI3K -mammalian target of rapamycin MTOR signaling pathways have recently been shown to cause several genetic disorders classified as neuro-cardio-facial-cutaneous NCFC and Hamartoma syndromes.
Although these pathways are well-known players in cell proliferation and cancer, their role in cognitive function is less appreciated. Cancer drugs have been shown to reverse the cognitive deficits in mouse models of NCFC and Hamartoma syndromes, raising hopes for clinical trials. Of the two complexes, mTORC1 couples nutrient abundance to cell growth and proliferation by sensing and integrating a variety of inputs arising from amino acids, cellular stresses, energy status, and growth factors. Defects in mTORC1 regulation are implicated in the development of many metabolic diseases, including cancer and diabetes.
Over the past decade, significant advances have been made in deciphering the complexity of the signaling processes contributing to mTORC1 regulation and function, but the mechanistic details are still not fully understood. In particular, how amino acid availability is sensed by cells and signals to mTORC1 remains unclear.
In this review, we discuss the current understanding of nutrient-dependent control of mTORC1 signaling and will focus on the key components involved in amino acid signaling to mTORC1. Oridonin, an ent-kaurane diterpenoid compound isolated from the traditional Chinese herb Rabdosia rubescens, has shown various pharmacological and physiological effects such as anti-tumor, anti-bacterial, and anti-inflammatory properties. However, the effect of oridonin on human ovarian cancer cell lines has not been determined.
In this study, we demonstrated that oridonin inhibited ovarian cancer cell proliferation, migration and invasion in a dose-dependent manner. Furthermore, we showed oridonin inhibited tumor growth of ovarian cancer cells SKOV3 in vivo. In summary, our results indicate that oridonin is a potential inhibitor of ovarian cancer by blocking the mTOR signaling pathway.
The circadian clock, an internal time-keeping system, has been linked with control of aging, but molecular mechanisms of regulation are not known. BMAL1 is a transcriptional factor and core component of the circadian clock; BMAL1 deficiency is associated with premature aging and reduced lifespan. We propose that the circadian clock controls the activity of the mTOR pathway through BMAL1-dependent mechanisms and this regulation is important for control of aging and metabolism.
Khapre, Rohini V. Fluoxetine regulates mTOR signalling in a region-dependent manner in depression-like mice. Previous studies have demonstrated that the mammalian target of rapamycin mTOR signaling pathway has an important role in ketamine-induced, rapid antidepressant effects despite the acute administration of fluoxetine not affecting mTOR phosphorylation in the brain.
However, the effects of long-term fluoxetine treatment on mTOR modulation have not been assessed to date. In the present study, we examined whether fluoxetine, a type of commonly used antidepressant agent, alters mTOR signaling following chronic administration in different brain regions, including the frontal cortex, hippocampus, amygdala and hypothalamus.
We also investigated whether fluoxetine enhanced synaptic protein levels in these regions via the activation of the mTOR signaling pathway and its downstream regulators, p70S6K and 4E-BP The results indicated that chronic fluoxetine treatment attenuated the chronic, unpredictable, mild stress CUMS -induced mTOR phosphorylation reduction in the hippocampus and amygdala of mice but not in the frontal cortex or the hypothalamus.
Moreover, the CUMS-decreased PSD and synapsin I levels were reversed by fluoxetine, and these effects were blocked by rapamycin only in the hippocampus. In conclusion, our findings suggest that chronic treatment with fluoxetine can induce synaptic protein expression by activating the mTOR signaling pathway in a region-dependent manner and mainly in the hippocampus. Georges, John; Sharp, Matthew H. Introduction Krill oil supplementation has been shown to improve postexercise immune function; however, its effect on muscle hypertrophy is currently unknown.
Therefore, the aim of present study was to investigate the ability of krill oil to stimulate mTOR signaling and its ability to augment resistance training-induced changes in body composition and performance. Methods C2C12 myoblasts cells were stimulated with krill oil or soy-derived phosphatidylcholine S-PC , and then, the ratio of P-p to total p70 was used as readout for mTOR signaling. Body composition, maximal strength, peak power, and rate of perceived recovery were assessed collectively at the end of weeks 0 and 8.
In addition, safety parameters comprehensive metabolic panel CMP , complete blood count CBC , and urine analysis UA and cognitive performance were measured pre- and posttesting. Conclusion Krill oil activates mTOR signaling. Krill oil supplementation in athletes is safe, and its effect on resistance exercise deserves further research.
The precise role of mTOR in the control of regulatory T cell Treg differentiation and function is complex. Pharmacologic inhibition and genetic deletion of mTOR promotes the generation of Tregs even under conditions that would normally promote generation of effector T cells.
In this study, by employing both pharmacologic inhibitors and genetically altered T cells, we seek to clarify the role of mTOR in Tregs. Our studies demonstrate that inhibition of mTOR during T cell activation promotes the generation of long-lived central Tregs with a memory-like phenotype in mice. Estradiol-induced object recognition memory consolidation is dependent on activation of mTOR signaling in the dorsal hippocampus.
The mammalian target of rapamycin mTOR signaling pathway is an important regulator of protein synthesis and is essential for various forms of hippocampal memory. We then showed that an increase in dorsal hippocampal ERK phosphorylation 5 min after intracerebroventricular ICV E2 infusion was also blocked by dorsal hippocampal infusion of the three cell signaling inhibitors.
Collectively, these data demonstrate for the first time that activation of the dorsal hippocampal mTOR signaling pathway is necessary for E2 to enhance object recognition memory consolidation and that E2-induced mTOR activation is dependent on upstream activation of ERK and PI3K signaling. Hypothalamic roles of mTOR complex I: integration of nutrient and hormone signals to regulate energy homeostasis.
Understanding the role and underlying mechanisms behind mTOR-related signaling in the brain will undoubtedly pave new avenues for future therapeutics and interventions that can combat obesity, insulin resistance, and diabetes. Hair follicles HFs undergo cycles of degeneration catagen , rest telogen , and regeneration anagen phases. Anagen begins when the hair follicle stem cells HFSCs obtain sufficient activation cues to overcome suppressive signals , mainly the BMP pathway, from their niche cells.
By using both an inducible conditional gene targeting strategy and a pharmacological inhibition method to ablate or inhibit mTOR signaling in adult skin epithelium before anagen initiation, we demonstrate that HFs that cannot respond to mTOR signaling display significantly delayed HFSC activation and extended telogen.
Our findings reveal a critical role for mTOR signaling in regulating stem cell activation through counterbalancing BMP-mediated repression during hair regeneration. Tissue-resident immune cells must balance survival in peripheral tissues with the capacity to respond rapidly upon infection or tissue damage, and in turn couple these responses with intrinsic metabolic control and conditions in the tissue microenvironment. This review discusses the function of mTOR signaling in the differentiation and function of tissue-resident immune cells, with focus on the role of mTOR as a metabolic sensor and its impact on metabolic regulation in innate and adaptive immune cells.
We also discuss the impact of metabolic constraints in tissues on immune homeostasis and disease, and how manipulating mTOR activity with drugs such as rapamycin can modulate immunity in these contexts. Published by Elsevier Inc. Repression of protein translation and mTOR signaling by proteasome inhibitor in colon cancer cells. Wu, William Ka Kei, E-mail: wukakei cuhk. Protein homeostasis relies on a balance between protein synthesis and protein degradation.
The ubiquitin-proteasome system is a major catabolic pathway for protein degradation. In this respect, proteasome inhibition has been used therapeutically for the treatment of cancer. Whether inhibition of protein degradation by proteasome inhibitor can repress protein translation via a negative feedback mechanism, however, is unknown.
Knockdown of raptor, a structural component of mTOR complex 1, mimicked the anti-proliferative effect of MG To conclude, we demonstrate that the inhibition of protein degradation by proteasome inhibitor represses mTOR signaling and protein translation in colon cancer cells.
Previous studies have suggested a role for mammalian target of rapamycin mTOR signaling in the pathogenesis of cardiovascular diseases. Oil red O staining revealed a large accumulation of lipid droplets present in foam cells. The findings of the present study suggest that mTOR signaling promotes foam cell formation and inhibits foam. Mammalian TOR is inhibited by rapamycin which is potent suppressor of T cell Nature Reviews Molecular Cell Biology Edinger, A.
Ribosome production is an early event during skeletal muscle hypertrophy and precedes muscle protein accretion. Signaling via mTOR is crucial for ribosome production and hypertrophy; however, the mechanisms by which it regulates these processes remain to be identified.
Herein, we investigated the activation of mTOR signaling in hypertrophying myotubes and determined that mTOR coordinates various aspects of gene expression important for ribosome production. First, inhibition of translation with cycloheximide had a more potent effect on protein synthesis than rapamycin indicating that mTOR function during hypertrophy is not on general, but rather on specific protein synthesis.
Second, blocking Pol II transcription had a similar effect as Rapamycin and, unexpectedly, revealed the necessity of Pol II transcription for Pol I transcription, suggesting that mTOR may regulate ribosome production also by controlling Class II genes at the transcriptional level.
Third, Pol I activity is essential for rDNA transcription and, surprisingly, for protein synthesis as selective Pol I inhibition blunted rDNA transcription, protein synthesis, and the hypertrophic response of myotubes. Finally, mTOR has nuclear localization in muscle, which is not sensitive to rapamycin. Inhibition of mTOR signaling by rapamycin disrupted mTOR-rDNA promoter interaction and resulted in altered histone marks indicative of repressed transcription and formation of higher-order chromatin structure.
Thus mTOR signaling appears to regulate muscle hypertrophy by affecting protein synthesis, Class I and II gene expression, and chromatin remodeling. Changes in the activation of downstream signaling molecules of EGFR were analyzed. Denervation atrophy is independent from Akt and mTOR activation and is not rescued by myostatin inhibition. The purpose of our study was to compare two acquired muscle atrophies and the use of myostatin inhibition for their treatment.
Myostatin naturally inhibits skeletal muscle growth by binding to ActRIIB, a receptor on the cell surface of myofibers. Because blocking myostatin in an adult wild-type mouse induces profound muscle hypertrophy, we applied a soluble ActRIIB receptor to models of disuse limb immobilization and denervation sciatic nerve resection atrophy. We found that treatment of immobilized mice with ActRIIB prevented the loss of muscle mass observed in placebo-treated mice. Our results suggest that this protection from disuse atrophy is regulated by serum and glucocorticoid-induced kinase SGK rather than by Akt.
We then treated the denervated mice with the mTOR inhibitor rapamycin and found that, despite a reduction in mTOR activation, there is no alteration of the atrophy phenotype. Thus, our studies show that denervation atrophy is not only independent from Akt, SGK and mTOR activation but also has a different underlying pathophysiological mechanism than disuse atrophy.
Sixty-one human NETs were included into the study. Methods Sixty-one human NETs were included into the study. LL attenuates inflammatory impairment via mTOR signaling -dependent mitochondrial protection. The human cationic antimicrobial protein LL is a multifunctional host defense peptide with a wide range of immunomodulatory activities. Previous work has shown that LL exerts both pro- and anti-inflammatory effects.
The role of mitochondria in the skin inflammatory effects of LL has not been well studied. Therefore, our aim was to investigate the immunomodulatory effect of LL in HaCaT cells and to delineate the underlying mechanisms related to mitochondrial function. Immunohistochemistry results from tissue microarrays showed strong cytoplasmic LL staining in inflammatory cells in chronic dermatic inflammation.
The anti-inflammatory effects of LL are dependent upon its ability to increase mitochondrial biogenesis and to maintain mitochondrial homeostasis. In conclusion, these results suggest that high LL expression levels correlate with chronic skin inflammation; mitochondrial dysfunction occurs in HaCaT cells during inflammation; and LL attenuates inflammatory impairment by stimulating mitochondrial biogenesis and protecting mitochondrial function, which are dependent upon mTOR signaling.
These findings provide new insights into targeting mitochondria with LL to prevent skin inflammatory reactions. Tryptophan catabolism by indoleamine 2,3-dioxygenase IDO alters inflammation and favors T-cell tolerance in cancer, but the underlying molecular mechanisms remain poorly understood.
