Agouti-Related Protein: A secreted protein of approximately 131 amino acids that is related to AGOUTI SIGNALING PROTEIN and is also an antagonist of MELANOCORTIN RECEPTOR activity. It is expressed primarily in the HYPOTHALAMUS and the ADRENAL GLAND. As a paracrine signaling molecule, AGRP is known to regulate food intake and body weight. Elevated AGRP has been associated with OBESITY.Agouti Signaling Protein: A secreted protein of approximately 131 amino acids (depending on species) that regulates the synthesis of eumelanin (brown/black) pigments in MELANOCYTES. Agouti protein antagonizes the signaling of MELANOCORTIN RECEPTORS and has wide distribution including ADIPOSE TISSUE; GONADS; and HEART. Its overexpression in agouti mice results in uniform yellow coat color, OBESITY, and metabolic defects similar to type II diabetes in humans.Hair Color: Color of hair or fur.Receptors, Melanocortin: A family of G-protein-coupled receptors that have specificity for MELANOCYTE-STIMULATING HORMONES and ADRENOCORTICOTROPIC HORMONE. There are several subtypes of melanocortin receptors, each having a distinct ligand specificity profile and tissue localization.Receptors, Corticotropin: Cell surface receptors that bind CORTICOTROPIN; (ACTH, adrenocorticotropic hormone) with high affinity and trigger intracellular changes. Pharmacology suggests there may be multiple ACTH receptors. An ACTH receptor has been cloned and belongs to a subfamily of G-protein-coupled receptors. In addition to the adrenal cortex, ACTH receptors are found in the brain and immune systems.Pigmentation: Coloration or discoloration of a part by a pigment.Intercellular Signaling Peptides and Proteins: Regulatory proteins and peptides that are signaling molecules involved in the process of PARACRINE COMMUNICATION. They are generally considered factors that are expressed by one cell and are responded to by receptors on another nearby cell. They are distinguished from HORMONES in that their actions are local rather than distal.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Proteins: Linear POLYPEPTIDES that are synthesized on RIBOSOMES and may be further modified, crosslinked, cleaved, or assembled into complex proteins with several subunits. The specific sequence of AMINO ACIDS determines the shape the polypeptide will take, during PROTEIN FOLDING, and the function of the protein.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Receptor, Melanocortin, Type 1: A melanocortin receptor subtype found primarily in MELANOCYTES. It shows specificity for ALPHA-MSH and ADRENOCORTICOTROPIC HORMONE. Loss of function mutations of the type 1 melanocortin receptor account for the majority of red hair and fair skin recessive traits in human.alpha-MSH: A 13-amino acid peptide derived from proteolytic cleavage of ADRENOCORTICOTROPIC HORMONE, the N-terminal segment of ACTH. ACTH (1-13) is amidated at the C-terminal to form ACTH (1-13)NH2 which in turn is acetylated to form alpha-MSH in the secretory granules. Alpha-MSH stimulates the synthesis and distribution of MELANIN in MELANOCYTES in mammals and MELANOPHORES in lower vertebrates.

Contribution of melanocortin receptor exoloops to Agouti-related protein binding. (1/265)

Agouti-related protein (AGRP) is an endogenous antagonist of melanocortin action that functions in the hypothalamic control of feeding behavior. Although previous studies have shown that AGRP binds three of the five known subtypes of melanocortin receptor, the receptor domains participating in binding and the molecular interactions involved are presently unknown. The present studies were designed to examine the contribution of extracytoplasmic domains of the melanocortin-4 receptor (MC4R) to AGRP binding by making chimerical receptor constructs of the human melanocortin-1 receptor (MC1R; a receptor that is not inhibited by AGRP) and the human MC4R (a receptor that is potently inhibited by AGRP). Substitutions of the extracytoplasmic NH2 terminus and the first extracytoplasmic loop (exoloop) of the MC4R with homologous domains of the MC1R had no effect on AGRP (87-132) binding affinity or inhibitory activity (the ability to inhibit melanocortin-stimulated cAMP generation). In contrast, cassette substitutions of exoloops 2 and 3 of the MC4R with the homologous exoloops of the MC1R resulted in a substantial loss of AGRP binding affinity and inhibitory activity. Conversely, the exchange of exoloops 2 and 3 of the MC1R with the homologous exoloops of the MC4R was found to confer AGRP binding and inhibitory activity to the basic structure of the MC1R. Importantly, these substitutions did not affect the ability of the alpha-melanocyte stimulating hormone analogue [Nle4,D-Phe7] melanocyte stimulating hormone to bind or activate the chimeric receptors. These data indicate that exoloops 2 and 3 of the melanocortin receptors are important for AGRP binding.  (+info)

Down-regulation of melanocortin receptor signaling mediated by the amino terminus of Agouti protein in Xenopus melanophores. (2/265)

Agouti protein and Agouti-related protein (Agrp) regulate pigmentation and body weight, respectively, by antagonizing melanocortin receptor signaling. A carboxyl-terminal fragment of Agouti protein, Ser73-Cys131, is sufficient for melanocortin receptor antagonism, but Western blot analysis of skin extracts reveals that the electrophoretic mobility of native Agouti protein corresponds to the mature full-length form, His23-Cys131. To investigate the potential role of the amino-terminal residues, we compared the function of full-length and carboxyl-terminal fragments of Agrp and Agouti protein in a sensitive bioassay based on pigment dispersion in Xenopus melanophores. We find that carboxyl-terminal Agouti protein, and all forms of Agrp tested, act solely by competitive antagonism of melanocortin action. However, full-length Agouti protein acts by an additional mechanism that is time- and temperature-dependent, depresses maximal levels of pigment dispersion, and is therefore likely to be mediated by receptor down-regulation. Apparent down-regulation is not observed for a mixture of amino-terminal and carboxyl-terminal fragments. We propose that the phenotypic effects of Agouti in vivo represent a bipartite mechanism: competitive antagonism of agonist binding by the carboxyl-terminal portion of Agouti protein and down-regulation of melanocortin receptor signaling by an unknown mechanism that requires residues in the amino terminus of the Agouti protein.  (+info)

NMR structure of a minimized human agouti related protein prepared by total chemical synthesis. (3/265)

The structure of the chemically synthesized C-terminal region of the human agouti related protein (AGRP) was determined by 2D 1H NMR. Referred to as minimized agouti related protein, MARP is a 46 residue polypeptide containing 10 Cys residues involved in five disulfide bonds that retains the biological activity of full length AGRP. AGRP is a mammalian signaling molecule, involved in weight homeostasis, that causes adult onset obesity when overexpressed in mice. AGRP was originally identified by homology to the agouti protein, another potent signaling molecule involved in obesity disorders in mice. While AGRP's exact mechanism of action is unknown, it has been identified as a competitive antagonist of melanocortin receptors 3 and 4 (MC3r, MC4r), and MC4r in particular is implicated in the hypothalamic control of feeding behavior. Full length agouti and AGRP are only 25% homologous, however, their active C-terminal regions are approximately 40% homologous, with nine out of the 10 Cys residues spatially conserved. Until now, 3D structures have not been available for either agouti, AGRP or their C-terminal regions. The NMR structure of MARP reported here can be characterized as three major loops, with four of the five disulfide bridges at the base of the structure. Though its fold is well defined, no canonical secondary structure is identified. While previously reported structural models of the C-terminal region of AGRP were attempted based on Cys homology between AGRP and certain toxin proteins, we find that Cys spacing is not sufficient to correctly determine the 3D fold of the molecule.  (+info)

Anatomy of an endogenous antagonist: relationship between Agouti-related protein and proopiomelanocortin in brain. (4/265)

Agouti-related protein (AGRP) is a recently discovered orexigenic neuropeptide that inhibits the binding and action of alpha-melanocyte-stimulating hormone derived from proopiomelanocortin (POMC) at the melanocortin 3 receptor (MC3R) and melanocortin 4 receptor (MC4R) and has been proposed to function primarily as an endogenous melanocortin antagonist. To better understand the interplay between the AGRP and melanocortin signaling systems, we compared their nerve fiber distributions with each other by immunohistochemistry and their perikarya distribution with MC3R and MC4R by double in situ hybridization. Although deriving from distinct cell groups, AGRP and melanocortin terminals project to identical brain areas. Both AGRP and melanocortin neurons selectively express the MC3R, which provides a neuroanatomical basis for a dual-input circuit with biological amplification and feedback inhibition. These studies highlight a broader complexity in POMC-mediated behavior in the brain.  (+info)

Involvement of agouti-related protein, an endogenous antagonist of hypothalamic melanocortin receptor, in leptin action. (5/265)

To understand the role of agouti-related protein (AGRP), an endogenous antagonist of hypothalamic melanocortin receptor, in leptin action, we produced a full-length recombinant AGRP and examined its effect on the satiety effect of leptin. We also studied leptin's regulation of hypothalamic AGRP mRNA expression. A single intracerebroventricular (i.c.v.) injection of AGRP significantly increased cumulative food intake and body weight in a dose-dependent manner in rats. The leptin-induced inhibition of food intake and body weight was reversed by co-injection of AGRP in a dose-dependent manner. Hypothalamic AGRP mRNA expression was upregulated in leptin-deficient ob/ob mice and leptin receptor-deficient db/db mice and downregulated in lethal yellow agouti mice (KKAy mice) with hyperleptinemia. A single i.c.v. injection of leptin reversed the increased AGRP mRNA levels in ob/ob mice but not in db/db mice. In control mice and KKAy mice, AGRP mRNA expression was upregulated during fasting, when plasma leptin concentrations were decreased. No significant increase in AGRP mRNA expression was noted during fasting in control mice and KKAy mice treated with leptin. This study provides the first direct evidence that AGRP is a negative regulator of leptin action, and leptin downregulates hypothalamic AGRP production. Because leptin is shown to increase hypothalamic alpha-melanocyte stimulating hormone (alpha-MSH) production, our data suggest that its action via the hypothalamic melanocortin system is determined by the balance between the levels of its agonist and antagonist, alpha-MSH and AGRP.  (+info)

Integration of NPY, AGRP, and melanocortin signals in the hypothalamic paraventricular nucleus: evidence of a cellular basis for the adipostat. (6/265)

Energy stores are held relatively constant in many mammals. The circuitry necessary for maintaining energy homeostasis should (1) sense the amount of energy stored in adipose tissue, (2) sense and integrate the multiple opposing signals regarding nutritional state, and (3) provide output regulating energy intake and expenditure to maintain energy homeostasis. We demonstrate that individual neurons within the paraventricular nucleus of the hypothalamus (PVH) are capable of detection and integration of orexigenic (neuropeptide Y [NPY]) and anorexigenic (melanocortin) signals, that NPY and melanocortins are functional antagonists of each other within the PVH in the regulation of feeding behavior, and that melanocortin administration within the PVH regulates both feeding behavior and energy expenditure. These data provide a cellular basis for the adipostat within neurons in the PVH that appear to be jointly regulated by NPY- and melanocortin-responsive neurons.  (+info)

The central melanocortin system affects the hypothalamo-pituitary thyroid axis and may mediate the effect of leptin. (7/265)

Prolonged fasting is associated with a downregulation of the hypothalamo-pituitary thyroid (H-P-T) axis, which is reversed by administration of leptin. The hypothalamic melanocortin system regulates energy balance and mediates a number of central effects of leptin. In this study, we show that hypothalamic melanocortins can stimulate the thyroid axis and that their antagonist, agouti-related peptide (Agrp), can inhibit it. Intracerebroventricular (ICV) administration of Agrp (83-132) decreased plasma thyroid stimulating hormone (TSH) in fed male rats. Intraparaventricular nuclear administration of Agrp (83-132) produced a long-lasting suppression of plasma TSH, and plasma T4. ICV administration of a stable alpha-MSH analogue increased plasma TSH in 24-hour-fasted rats. In vitro, alpha-MSH increased thyrotropin releasing hormone (TRH) release from hypothalamic explants. Agrp (83-132) alone caused no change in TRH release but antagonized the effect of alpha-MSH on TRH release. Leptin increased TRH release from hypothalami harvested from 48-hour-fasted rats. Agrp (83-132) blocked this effect. These data suggest a role for the hypothalamic melanocortin system in the fasting-induced suppression of the H-P-T axis.  (+info)

Widespread expression of Agouti-related protein (AGRP) in the chicken: a possible involvement of AGRP in regulating peripheral melanocortin systems in the chicken. (8/265)

Agouti-related protein (AGRP) is a naturally occurring antagonist of melanocortin action. It is expressed mainly in the arcuate nucleus where it plays an important role in the hypothalamic control of feeding and energy homeostasis by antagonism of central melanocortin 4 receptors in mammals. Besides in the brain, the melanocortin 4 receptor is expressed in numerous peripheral tissues in the chicken. To examine whether or not the peripheral melanocortin 4 receptor signaling could be regulated by AGRP, we cloned and localized the expression of the AGRP gene in the chicken. The chicken AGRP gene was found to encode a 154 or 165 amino acid protein, depending on the usage of two alternative translation initiation sites. The coding sequence consisted of three exons, like that of mammalian species. The C-terminal cysteine-rich region of the predicted AGRP displayed high levels of identity to mammalian counterparts (78-84%) and all 10 cysteine residues conferring functional conformation of AGRP were conserved; however, other regions showed apparently no homology, suggesting that biological activities of AGRP are located in its C-terminal region. RT-PCR analysis detected the AGRP mRNA in all tissues examined: the brain, adrenal gland, heart, liver, spleen, gonads, kidney, uropygial gland, skeletal muscle and adipose tissues. Interestingly, the skin also expressed the AGRP mRNA, where Agouti, another melanocortin receptor antagonist regulating hair pigmentation, is expressed in rodents. Most of those AGRP-expressing tissues have been demonstrated to express melanocortin 4 receptors and/or other subtypes of melanocortin receptor whose mammalian counterparts can bind AGRP. These results imply the possibility that some peripheral melanocortin systems could be regulated by the functional interaction between melanocortins and AGRP at melanocortin receptors in the chicken.  (+info)

Agouti-related protein (AgRP), also called agouti-related peptide, is a neuropeptide produced in the brain by the AgRP/NPY neuron. It is synthesised only in neuropeptide Y (NPY)-containing cell bodies located in the ventromedial part of the arcuate nucleus in the hypothalamus. AgRP is co-expressed with NPY and acts to increase appetite and decrease metabolism and energy expenditure. It is one of the most potent and long-lasting of appetite stimulators. In humans, the agouti-related peptide is encoded by the AGRP gene. AgRP is a paracrine signalling molecule made up of 112 amino acids (the gene product of 132 amino acids is processed by removal of the N-terminal 20-residue signal peptide domain). It was independently identified by two teams in 1997 based on its sequence similarity with agouti signalling peptide (ASIP), a protein synthesised in the skin that controls coat colour. AgRP is approximately 25% identical to ASIP. The murine homologue of AgRP consists of 111 amino acids (precursor is 131 ...

To further investigate the implication of MC system in chronic pain, we have used a double approach. From one side we have performed in vivo studies on the effects of several MC antagonists on animal models of persistent pain (spinal nerve ligation, chronic constriction injury and formalin). On the other hand we used immunocytochemical analysis and gene expression study to corroborate our in vivo finding. Our finding that the endogenous antagonist agouti related protein is present in key areas of the pain pathway suggests the hypothesis that the endogenous melanocortin system could modulate pain perception not only positively but also negatively. The antinociceptive effect induced by in vivo administration of the agouti related protein lends further support to this hypothesis. The experimental evidence gathered, together with the published data, suggest that MC analgesia is primary mediated by the MC 4 receptors. The development of non-peptidic selective MC4 receptor antagonists would be an ...

Intermittent fasting is an alternative to calorie restriction used primarily in lab experiments. It usually involves placing animals on a 24-hour on, 24-hour off feeding cycle, and usually results in weight loss. Several studies have suggested that it promotes a number of significant improvements in health. "We concluded that improvements in cardiovascular risk factors and cardiovascular and neuroendocrine stress adaptation occur in response to [intermittent fasting]," one study reported. Intermittent fasting caused changes in the hypothalamus of rats that may explain the low feeding efficiency, reduced body mass, and overeating seen in these animals, researchers reported.. Though most of the research on the benefits of intermittent fasting has been done in lab animals, research is starting to be done in humans, and the results are similar to those seen in animals..

Several different neuronal populations are involved in regulating energy homeostasis. Among these, agouti-related protein (AgRP) neurons are thought to promote feeding and weight gain; however, the evidence supporting this view is incomplete. Using designer receptors exclusively activated by designer drugs (DREADD) technology to provide specific and reversible regulation of neuronal activity in mice, we have demonstrated that acute activation of AgRP neurons rapidly and dramatically induces feeding, reduces energy expenditure, and ultimately increases fat stores. All these effects returned to baseline after stimulation was withdrawn. In contrast, inhibiting AgRP neuronal activity in hungry mice reduced food intake. Together, these findings demonstrate that AgRP neuron activity is both necessary and sufficient for feeding. Of interest, activating AgRP neurons potently increased motivation for feeding and also drove intense food-seeking behavior, demonstrating that AgRP neurons engage brain sites ...

Leptin contributes to the control of resting metabolic rate (RMR) and blood pressure (BP) through its actions in the arcuate nucleus (ARC). The renin-angiotensin system (RAS) and angiotensin AT1 receptors within the brain are also involved in the control of RMR and BP, but whether this regulation overlaps with leptins actions is unclear. Here, we have demonstrated the selective requirement of the AT1A receptor in leptin-mediated control of RMR. We observed that AT1A receptors colocalized with leptin receptors (LEPRs) in the ARC. Cellular coexpression of AT1A and LEPR was almost exclusive to the ARC and occurred primarily within neurons expressing agouti-related peptide (AgRP). Mice lacking the AT1A receptor specifically in LEPR-expressing cells failed to show an increase in RMR in response to a high-fat diet and deoxycorticosterone acetate-salt (DOCA-salt) treatments, but BP control remained intact. Accordingly, loss of RMR control was recapitulated in mice lacking AT1A in AgRP-expressing ...
Hypothalamus is a key area involved in the control of metabolism and food intake via the integrations of numerous signals (hormones, neurotransmitters, metabolites) from various origins. These factors modify hypothalamic neurons activity and generate adequate molecular and behavioral responses to control energy balance. In this complex integrative system, a new concept has been developed in recent years, that includes reactive oxygen species (ROS) as a critical player in energy balance. ROS are known to act in many signaling pathways in different peripheral organs, but also in hypothalamus where they regulate food intake and metabolism by acting on different types of neurons, including proopiomelanocortin (POMC) and agouti-related protein (AgRP)/neuropeptide Y (NPY) neurons. Hypothalamic ROS release is under the influence of different factors such as pancreatic and gut hormones, adipokines (leptin, apelin,...), neurotransmitters and nutrients (glucose, lipids,...). The sources of ROS production are

The understanding of adipose tissue role has evolved from that of a depot energy storage organ to a dynamic endocrine organ. While genetics, sexual phenotype and sex steroids can impact the mass and distribution of adipose tissue, there is a counter-influence of white adipocytes on reproduction. This primarily occurs via the secretion of adipokines, the most studied of which- leptin and adiponectin- are highlighted in this article. Leptin, the "satiety hormone" primarily acts on the hypothalamus via pro-opiomelanocortin (POMC), neuropeptide Y (NPY), and agouti-related peptide (AgRP) NPY neurons to translate acute changes in nutrition and energy expenditure, as well as chronic adipose accumulation into changes in appetite and potentially mediate insulin resistance via shared pathway and notably impacting reproductive health via influence on GnRH secreting neurons ...
Alcohol switches the brain into starvation mode, increasing hunger and appetite, scientists have discovered. In tests on mice, alcohol activated the brain signals that tell the body to eat more food.. The UK researchers, who report their findings in the journal Nature Communications, believe the same is probably true in humans. It would explain why many people say they eat more when they have had a few drinks. Rather than loss of restraint, it is a neuronal response, the Francis Crick Institute team says. The mice were given generous doses of alcohol for three days - a dose being equivalent to around 18 units or a bottle-and-a-half of wine for a person. The alcohol caused increased activity in neurons called AGRP. These are the neurons that are fired when the body experiences starvation. The mice ate more than normal too. When the researchers repeated the experiment but blocked the neurons with a drug, the mice did not eat as much which, the researchers say, suggests that AGRP neurons are ...
The distribution of leptin receptor, POMC, AGRP, MCH, and orexin mRNAs in the hamster hypothalamus (Fig. 1) was consistent with other rodent species. The strategy we adopted allowed quantification of a number of mRNA species in a nominated hypothalamic nucleus from an individual animal. This necessitated that only every eighth section was hybridized with any individual probe, and it is therefore possible that very localized changes in gene expression could be overlooked. We provide evidence of the regulation by photoperiod of POMC, AGRP, and OB-Rb gene expression in the ARC. In addition, AGRP gene expression was strongly regulated by FD, whereas more discrete effects were observed for OB-R, OB-Rb, NPY, and POMC mRNAs. It is anticipated that changes in mRNA levels will be translated into differences in peptide synthesis, as indicated in one of our earlier studies (28), and will thus be of functional significance. These changes were set against a background of changes in plasma concentrations of ...

Current evidence suggests that ghrelin, a stomach derived peptide, exerts its orexigenic action through specific modulation of Sirtuin1 (SIRT1)/p53 and AMP-activated protein kinase (AMPK) pathways, which ultimately increase the expression of agouti-related protein (AgRP) and neuropeptide Y (NPY) in the arcuate nucleus of the hypothalamus (ARC). However, there is a paucity of data about the possible action of ghrelin on alternative metabolic pathways at this level. Here, we demonstrate that ghrelin elicits a marked upregulation of the hypothalamic mammalian target of rapamycin (mTOR) signaling pathway. Of note, central inhibition of mTOR signaling with rapamycin decreased ghrelins orexigenic action and normalized the mRNA expression of AgRP and NPY, as well as their key downstream transcription factors, namely cAMP response-element binding protein (pCREB) and forkhead box O1 (FoxO1, total and phosphorylated). Taken together, these data indicate that, in addition to previous reported mechanisms, ghrelin

the onset of puberty is the culmination of a subtle shift in balance of stimulatory and inhibitory neurotransmission within a complex neural network. Whereas the intrinsic pulsatility of GnRH neurons points toward a cell-autonomous function of gonadotropin-releasing hormone (GnRH) secretion, extrinsic signals are likely to be required to trigger activity in quiescent GnRH neurons. There is undoubtedly a link between metabolic status and GnRH activity (34). In the context of normal leptin signaling, a role has been implicated on the basis of a direct correlation between puberty onset and body weight (8, 16). Additionally, cases of defective leptin signaling in both humans and rodents result in hypogonadotropic hypogonadism (13). In a case report of a girl with leptin deficiency, treatment with leptin appeared to reverse the hypogonadal state (12). In cases of lipodystrophy with attendant hypoleptinemia, leptin therapy normalized pituitary hormone release (29) and restored menstrual cycles to all ...
We used microarray and quantitative real-time PCR (qRT-PCR) analyses in adult female zebrafish (Danio rerio) to identify metabolic pathways regulated by starvation in the liver and brain. The transcriptome of whole zebrafish brain showed little response to 21 days of starvation. Only agouti-related protein 1 (agrp1) significantly responded, with increased expression in brains of starved fish. In contrast, a 21-day period of starvation significantly downregulated 466 and upregulated 108 transcripts in the liver, indicating an overall decrease in metabolic activity, reduced lipid metabolism, protein biosynthesis, proteolysis, and cellular respiration, and increased gluconeogenesis. Starvation also regulated expression of many components of the unfolded protein response, the first such report in a species other than yeast (Saccharomyces cerevisiae) and mice (Mus musculus). The response of the zebrafish hepatic transcriptome to starvation was strikingly similar to that of rainbow trout (Oncorhynchus mykiss)
Lesioning studies performed nearly 100 years ago identified the hypothalamus as a critical structure for the control of food intake. However the dynamics of the hypothalamic circuits that give rise to feeding behavior have long been a mystery. In 2015, we reported the first measurements of the activity dynamics of hypothalamic neurons that control hunger (AgRP neurons) in awake, behaving mice (Chen et al., Cell 2015). Prior to our work, these cells were thought to be regulated primarily by hormones and nutrients that circulate in the blood, such that their activity would gradually fluctuate in unison with changes in nutritional state. We discovered unexpectedly that these hunger neurons are also potently regulated by sensory cues associated with food: that is, we found that merely showing a piece of food to a hungry mouse was sufficient to shut off its AgRP neurons within seconds, often before a single bite of food could be consumed. We showed that this sensory regulation resembles an expected ...
Bodyweight and food intake are regulated by the hypothalamus which integrates peripheral hormonal and neural signals. The G-protein-coupled melanocortin-receptors 3 and 4 (MC3R and MC4R) are activated by melanocortins or inhibited by agouti-related pepetide (AgRP) and signal via the cAMP pathway. Brain-derived neurotrophic Factor (BDNF) was recently shown to signal downstream the MC4R via its receptor TrkB (tropomyosin-related kinase). Mutations in the MC4R are the most common cause of monogenetic obesity. However, many of these mutations are not functionally relevant in vitro. Here, an amino acid alignment of orthologous MC4R from over 70 species was used to evaluate reported mutations. Loss-of-function mutations were predominantly located at highly conserved positions whereas mutations without effect were located at non-conserved positions. Functional characterization of MC4R point mutations I194F (partial loss of function) and Y302C (complete loss of function) identified in mouse models ...

Nevertheless, the mechanisms underlying these effects are not completely understood because central and peripheral actions of IL-6 are plausible. To gain further insight into the central effects of IL-6, we used transgenic mice expressing the IL-6 gene under the control of the glial fibrillary acidic protein (GFAP) promoter (GFAP-IL-6 mice), therefore with central nervous system-restricted over-expression of IL-6, and we studied the expression of the main neuropeptides responsible for energy homeostasis in specific hypothalamic nuclei.

Perhaps one of the most interesting aspects of the melanocortin system is that it has two endogenous antagonists, agouti and AGRP. These proteins are unique in that no inhibitory proteins have been identified for any of the seven-transmembrane receptor family. Agouti and AGRP are paracrine signaling molecules, which are endogenous antagonists of the MCRs (13). Of physiological significance, agouti and AGRP have MCR subtype selectivity (Table 1). Interestingly, agouti and AGRP both have a cysteine-rich COOH-terminal domain. Although the structure of agouti has not been resolved, nuclear magnetic resonance studies demonstrate that the cysteine residues in AGRP adopt a structural motif called an inhibitor cystine knot (32). This motif is common to invertebrate toxins, but in mammals this structure is unique to AGRP and, presumably, agouti. Another commonality is that agouti and AGRP have both been shown in vitro to be inverse agonists (33). Thus they have the potential in vivo to regulate their ...
According to a research report published in The European Molecular Biology Organization (EMBO) Journal, lack of AgRP-neurons, brain cells involved in controlling food intake, led to obesity if the mice studied were fed a regular carbohydrate diet. However, when the animals are raised on a high-fat diet, they end up leaner and healthier.. The different outcomes are due to how the AgRP neurons influence the way the body breaks down and stores nutrients. Mice that lack the brain neurons dont adapt well to a carbohydrate diet and appear to have a metabolism best suited for a high-fat diet.. Your genetics, diet and exercise habits are all major players in your weight and overall health. However, Serge Luquet, lead author of the study, says its "not just a question of what you eat and your genetic makeup, but also how the body manages to convert, store and use food nutrients.". The researchers wanted to see if the AgRP neurons had additional influence beyond what scientists already knew about its ...
The hypothalamus has gained attention for its involvement in regulating energy metabolism via its ability to receive and integrate signals from peripheral sites and produce a variety of signaling molecules in response to changes in energy status to ultimately maintain energy homeostasis (14, 36, 41). We hypothesized that changes in hypothalamic gene expression exist between lines divergently selected for heat loss as correlated responses to selection and that these changes can account for some of the phenotypic differences in traits related to energy balance between the high and low heat loss lines.. The microarray experiments identified potential candidate genes that could be involved in regulating energy balance and contribute to a portion of the phenotypic differences that are observed between the high and low heat loss selection lines. Surprisingly, only a few genes were found with significant differential expression between the lines according to the microarrays. Even fewer genes were ...

Aberrant melanocortin signaling has been implicated in the pathogenesis of wasting in chronic kidney disease (CKD). Previously, we demonstrated that agouti-related peptide (AgRP), a melenocortin-4 receptor antagonist, reduced CKD-associated cachexia in CKD mice. Our previous studies with AgRP utilized dual energy X-ray (DXA) densitometry to assess the body composition in mice (Cheung W, Kuo HJ, Markison S, Chen C, Foster AC, Marks DL, Mak RH. J Am Soc Nephrol 18: 2517-2524, 2007; Cheung W, Yu PX, Little BM, Cone RD, Marks DL, Mak RH. J Clin Invest 115: 1659-1665, 2005). DXA is unable to differentiate water content in mice, and fluid retention in CKD may lead to an overestimate of lean mass. In this study, we employed quantitative magnetic resonance technique to evaluate body composition change following central administration of AgRP in a CKD mouse model. AgRP treatment improved energy expenditure, total body mass, fat mass, and lean body mass in CKD mouse. We also investigated the effect of ...
BMPs in the Development of Enteric Neurons Alcmène Chalazonitis, Fabien DAutréaux, Udayan Guha, Tuan D. Pham, Christophe Faure, Jason J. Chen, Daniel Roman, Lixin Kan, Taube P. Rothman, John A. Kessler, and Michael D. Gershon. (see pages 4266-4282). The influence of the local environment drives the development of the enteric nervous system (ENS) that derives from the neural crest. Bone morphogenetic proteins (BMPs), not being deterred by their name, influence developmental processes in many tissues, including the gut. In this issue, Chalazonitis et al. set out to determine the role of BMP-2 and -4 on the specification and differentiation of enteric neurons. They examined the ENS of mice at embryonic day 12 when neurons first appear in the gut. BMPs, their cognate receptors, as well as several endogenous antagonists were identified in populations of neural crest-derived and non-crest-derived cells. Using transgenic mice that overexpress the endogenous antagonist noggin and thus sequester ...
Introduction: Conflicting data exist on sensitivity changes of the melanocortin system during diet-induced obesity. We hypothesized that melanocortin sensitivity depends on diet composition, in particular on the fat content rather than the level of obesity. The aim of this study was to determine the influence of diet composition on feeding responses to a melanocortin receptor agonist, using free-choice diets that differ in food components.Methods: Male Wistar rats were subjected to a chow (CHOW) diet or a free-choice (fc) diet of either chow, saturated fat and liquid sugar (fcHFHS), chow and saturated fat (fcHF), or chow and liquid sugar (fcHS) for 4 weeks. Melanocortin sensitivity was tested by measuring food intake following administration of the melanocortin 3/4 receptor agonist melanotan II (MTII) or vehicle in the lateral ventricle. In a separate experiment, POMC and AgRP mRNA levels were determined in the arcuate nucleus with in situ hybridization in rats subjected to the free-choice diets for 4

Brexpiprazole (3.0mg/kg, PO), escitalopram (5.0mg/kg, IP) and their combination were administered twice daily for 14 days, starting 14 days after exposure to PSS or sham-PSS, shortly after a situational stress reminder. One day after last treatment behavioral responsivity was assessed. Brexpiprazole+escitalopram-treated rats spent more time in open arms, entered open arms more often and exhibited a lower anxiety index in the elevated plus maze than vehicle-treated, PSS-exposed rats ...
California-based Isis Pharmaceuticals may have discovered an effective treatment for Amytrophic Lateral Sclerosis (ALS), also known as Lou Gehrigs disease
Melanin-concentrating hormone (MCH) and orexin-A are orexigenic peptidergic neurotransmitters produced primarily in the lateral hypothalamus. Because two other hypothalamic peptides, neuropeptide Y and agouti-related peptide, increase food intake by a mechanism that depends on activation of opioid receptors, we assessed whether MCH or orexin-A also elicits food intake via opioid receptor activation. A dose of naloxone (0.3 mg/kg, ip) that had no effect on its own reduced the acute orexigenic effect of third ventricular (i3vt) orexin-A (3 ng/rat). However, this same dose of naloxone had no effect on i3vt MCH (5 microg/rat)-induced hyperphagia. Because the opioid system has also been linked to food selection, we investigated whether MCH or orexin-A alters food choice when rats have simultaneous access to two diets differing in the relative amounts of fat and carbohydrate. Whereas i3vt MCH stimulated intake of both diets and did not alter food choice, i3vt orexin-A stimulated intake of only the high fat

Epigenetic regulation of neuropeptide genes associated with central appetite control plays an important part in the development of nutritional programming. While POMC is critical in appetite control, the molecular mechanism of methylation-related regulation of POMC remains unclear. Based on the report that the proximal Sp1 binding site in POMC promoter is crucial for the leptin-mediated activation of POMC, the methylation of this site was investigated here in both cultured cells and postnatal mice reared by the dams with dietary supplementation of CLA. The change of milk composition made the offspring undergo the increase of food intake, the suppression of POMC, the attenuation of Sp1-promoter interaction and the hypermethylation of CpG dinucleotides at -100 and -103 within Sp1 binding site of POMC promoter, which may be associated with the decrease of hypothalamic Sp1 and/or plasma S-adenosylhomocystein. In cultured cells the methylation of the -100 CpG dinucleotides of POMC promoter blocked ...

An important finding of this study is that chronic blockade of the MC3/4-R markedly reduced arterial pressure in SHR while causing only a small reduction in arterial pressure of normotensive WKY rats. MC3/4-R antagonism also markedly reduced heart rate, but to a similar extent in SHR and WKY. Furthermore, this study demonstrated that the reductions in arterial pressure and heart rate caused by MC3/4R blockade occurred despite hyperphagia and pronounced weight gain in both groups. This suggests that blood pressure in SHR is controlled, at least in part, by the central MC3/4-R, and supports our previous findings that weight gain is not associated with increased arterial pressure and heart rate in the absence of a functional central melanocortin system.10. The fact that blockade of the melanocortin system caused a greater fall in blood pressure in SHR, a hypertensive strain of rats known for its sympathetic overactivity, and that MC3/4-R antagonism failed to lower arterial pressure in the presence ...
Title: The CNS Melanocortin System: A Biological Weapon Against the Threat of Obesity. VOLUME: 3 ISSUE: 3. Author(s):M. M. Hagan, P. C. Chandler and P. K. Wauford. Affiliation:Department of Psychology, Division of Behavioral Neuroscience, University of Alabama atBirmingham, Birmingham, AL 35294-1170, USA.. Keywords:pomc, alpha-melanocyte stimulating hormone, energy balance, food intake. Abstract: Commensurate with the last decades increasing prevalence of obesity is the number of breakthroughs in the physiology of energy regulation. Primary of these is the role played by the CNS melanocortin 3 and 4 receptors (MC3 / 4R). The MC3 / 4 ligand, alpha-melanocyte stimulating hormone, is a primary anti-obesity target due to its anorectic and catabolic actions. A level of complexity is introduced by agouti related peptide, an endogenous antagonist at the MC3 / 4R that exerts orexigenic and anabolic functions. Here we evidence the utility of the MC system to treat obesity by reviewing the long-lasting ...
The melanocortin receptor family includes five subtypes, named MC1R to MC5R. Melanocortin receptors are predominantly coupled to second messenger pathway of cyclic AMP through coupling to G-protein. This study is focused on structure-function relationship of MC1R and MC5R. Results demonstrate that (i) mutations D117A and H260A in MC1R decrease the affinity for natural melanocortins (L-isomer) but not for the synthetic analogue NDP-MSH (D-isomer), (ii) reduction of disulphide bonds in MC1R with DTT resulted in decrease in binding of 125I-ACTH in an uniphasic manner and decrease in binding of 125I-NDP-MSH in biphasic manner (iii) single point mutations of four cysteine residues to glycine in extracellular loops of MC1R resulted in a complete loss of ligand binding, (iv) mutant at position C78 in MC1R with wild type ligand binding generated a cAMP signal only in response to α-MSH but not to NDP-MSH, moreover,this single amino acid substitution converted NDP-MSH from being an agonist at wild type ...
