Metabotropic Glutamate Receptors
mGluR Metabotropic glutamate receptors mGluR (metabotropic glutamate receptor) is a type of glutamate receptor that are active through an indirect metabotropic process. They are members of thegroup C family of G-protein-coupled receptors, or GPCRs. Like all glutamate receptors, mGluRs bind with glutamate, an amino acid that functions as an excitatoryneurotransmitter. The mGluRs perform a variety of functions in the central and peripheral nervous systems: mGluRs are involved in learning, memory, anxiety, and the perception of pain. mGluRs are found in pre- and postsynaptic neurons in synapses of the hippocampus, cerebellum, and the cerebral cortex, as well as other parts of the brain and in peripheral tissues. Eight different types of mGluRs, labeled mGluR1 to mGluR8, are divided into groups I, II, and III. Receptor types are grouped based on receptor structure and physiological activity. www.MedChemExpress.com 1 mGluR Agonists, Antagonists, Inhibitors, Modulators & Activators (-)-Camphoric acid (1R,2S)-VU0155041 Cat.

The G Protein-Coupled Glutamate Receptors As Novel Molecular Targets in Schizophrenia Treatment— a Narrative Review
Journal of Clinical Medicine Review The G Protein-Coupled Glutamate Receptors as Novel Molecular Targets in Schizophrenia Treatment— A Narrative Review Waldemar Kryszkowski 1 and Tomasz Boczek 2,* 1 General Psychiatric Ward, Babinski Memorial Hospital in Lodz, 91229 Lodz, Poland; [email protected] 2 Department of Molecular Neurochemistry, Medical University of Lodz, 92215 Lodz, Poland * Correspondence: [email protected] Abstract: Schizophrenia is a severe neuropsychiatric disease with an unknown etiology. The research into the neurobiology of this disease led to several models aimed at explaining the link between perturbations in brain function and the manifestation of psychotic symptoms. The glutamatergic hypothesis postulates that disrupted glutamate neurotransmission may mediate cognitive and psychosocial impairments by affecting the connections between the cortex and the thalamus. In this regard, the greatest attention has been given to ionotropic NMDA receptor hypofunction. However, converging data indicates metabotropic glutamate receptors as crucial for cognitive and psychomotor function. The distribution of these receptors in the brain regions related to schizophrenia and their regulatory role in glutamate release make them promising molecular targets for novel antipsychotics. This article reviews the progress in the research on the role of metabotropic glutamate receptors in schizophrenia etiopathology. Citation: Kryszkowski, W.; Boczek, T.

Regulation of Drosophila Rest: Activity Rhythms by a Microrna and Aging Abstract Although there has been much progress in deciphering the molecular basis of the circadian clock, major questions remain about clock mechanisms and about the control of behavior and physiology by the clock. In particular, mechanisms that transmit time-of-day signals from the clock and produce rhythmic behaviors are poorly understood. Also, it is not known why rest:activity rhythms break down with age. In this thesis, we used a Drosophila model to address some of these questions. We identified a pathway that is required downstream of the clock for rhythmic rest:activity and also explored the mechanisms that account for deterioration of behavioral rhythms with age. By investigating candidate circadian mutants identified in a previous genetic screen in the laboratory, we discovered a circadian function of a microRNA gene, miR-279. We found that miR-279 acts through the JAK/STAT pathway to drive rest:activity rhythms. -
Metabotropic Glutamate Receptor 7 Modulates the Rewarding Effects of Cocaine in Rats: Involvement of a Ventral Pallidal Gabaergic Mechanism

In this study, we investigated the possible involvement of mGluR7 in cocaine reward in animal models of drug addiction. Pretreatment with the selective mGluR7 allosteric agonist N,N’-dibenzyhydryl-ethane-1,2-diamine dihydrochloride (AMN082; 1-20 mg/kg, i.p.) dose-dependently inhibited cocaine-induced enhancement of electrical brain-stimulation reward and intravenous cocaine self-administration under both fixed-ratio and progressive-ratio reinforcement conditions, but failed to alter either basal or cocaine-enhanced locomotion or oral sucrose self-administration, suggesting a specific inhibition of cocaine reward. Microinjections of AMN082 (1–5 mg/ml per side) into the nucleus accumbens (NAc) or ventral pallidum (VP), but not dorsal striatum, also inhibited cocaine self-administration in a dose-dependent manner. Intra-NAc or intra-VP co-administration of 6-(4-methoxyphenyl)-5-methyl-3-pyridin- 4-ylisoxazolo[4,5-c]pyridin-4(5H)-one (MMPIP, 5 mg/ml per side), a selective mGluR7 allosteric antagonist, significantly blocked AMN082’s action, suggesting an effect mediated by mGluR7 in these brain regions. -

Oncogenic Myc Disrupts the Molecular Clock and Metabolism in Cancer
ONCOGENIC MYC DISRUPTS THE MOLECULAR CLOCK AND METABOLISM IN CANCER CELLS AND DROSOPHILA by Annie Lee Hsieh A dissertation submitted to Johns Hopkins University in conformity with the requirement for the degree of Doctor of Philosophy Baltimore, Maryland March 2016 ©Annie Lee Hsieh 2016 All right reserved Abstract Circadian rhythm is a biological rhythm with a period about 24 hours, which coordinates the organismal biological processes with environmental day and night cycle. This 24-hour rhythm is exhibited in every cell in the organism and is generated by the molecular clock circuitry that comprises transcriptional and translational feedback loops. While loss of circadian rhythm or alteration of clock gene expression is broadly observed in human cancers, the molecular basis underlying these perturbations and their functional implications are poorly understood. MYC oncogene is amplified in more than half of the human cancers. Its encoded protein, MYC, is a transcription factor that binds to the E- box sequence (5’-CACGTG-3’), which is the identical binding site of the master circadian transcription factor CLOCK::BMAL1. Thereby we hypothesized that deregulated circadian rhythm in cancer cells is a consequence of perturbation of E-box- containing clock genes by ectopically overexpressed MYC. In this thesis, we provide evidence that MYC or N-MYC activation alters expression of E-box-containing clock genes including PER1, PER2, REV-ERBα, REV- ERBβ and CRY1 in cell lines derived from human Burkitts lymphoma, human osteosarcoma, mouse hepatocellular carcinoma and human neuroblastoma. MYC activation also significantly suppress the expression and oscillation of the circadian transcription factor BMAL1. Although public available MYC ChIP-seq data suggest that MYC directly binds to the promoter of PER1, PER2, REV-ERBα, REV-ERBβ and CRY1 in U2OS cells, only silencing of REV-ERBα and REV-ERBβ is able to rescue BMAL1 suppression by MYC.
