Bitopic binding mode of an M1 muscarinic acetylcholine receptor agonist associated with adverse clinical trial outcomes [PDF]

open access: yes, 2018
The realisation of the therapeutic potential of targeting the M1 muscarinic acetylcholine receptor (M1 mAChR) for the treatment of cognitive decline in Alzheimer's disease has prompted the discovery of M1 mAChR ligands showing efficacy in alleviating ...

Identification and Molecular Characterization of m3 Muscarinic Receptor Dimers [PDF]

open access: yesJournal of Biological Chemistry, 1999
Several studies suggest, but do not prove directly, that muscarinic receptors may be able to form dimeric or oligomeric arrays. To address this issue in a more direct fashion, we designed a series of biochemical experiments using a modified version of the rat m3 muscarinic receptor (referred to as m3') as a model system.

M3 muscarinic acetylcholine receptor facilitates the endocytosis of mu opioid receptor mediated by morphine independently of the formation of heteromeric complexes [PDF]

open access: yes, 2017
Morphine inefficiency to induce the internalization of mu opioid (MOP) receptors observed in numerous experimental models constitutes a paradigm of G-protein coupled receptor (GPCR) functional selectivity.

Evidence for M2 and M3 Muscarinic Receptor Involvement in Cholinergic Excitatory Junction Potentials Through Synergistic Activation of Cation Channels in the Longitudinal Muscle of Mouse Ileum

open access: yesJournal of Pharmacological Sciences, 2013
Cholinergic nerve–mediated excitatory junction potentials (EJPs) in the longitudinal muscle of mouse ileum were characterized by using M2 or M3 muscarinic receptor–knockout (KO) mice and 1-[β-[3-(4-methoxyphenyl)propoxy]-4-methoxyphenethyl]-1H-imidazole ...

Inhibition of m3 muscarinic acetylcholine receptors by local anaesthetics [PDF]

open access: yesBritish Journal of Pharmacology, 2001
Muscarinic m1 receptors are inhibited by local anaesthetics (LA) at nM concentrations. To elucidate in more detail the site(s) of LA interaction, we compared these findings with LA effects on m3 muscarinic receptors. We expressed receptors in Xenopus oocytes.

Mir-34a-5p Mediates Cross-Talk between M2 Muscarinic Receptors and Notch-1/EGFR Pathways in U87MG Glioblastoma Cells: Implication in Cell Proliferation [PDF]

open access: yes, 2018
Glioblastoma (GBM) is the most aggressive human brain tumor. The high growth potential and decreased susceptibility to apoptosis of the glioma cells is mainly dependent on genetic amplifications or mutations of oncogenic or pro-apoptotic genes ...

Structural Basis of M3 Muscarinic Receptor Dimer/Oligomer Formation [PDF]

open access: yesJournal of Biological Chemistry, 2011
Class A G protein-coupled receptors (GPCRs) are known to form dimers and/or oligomeric arrays in vitro and in vivo. These complexes are thought to play important roles in modulating class A GPCR function. Many studies suggest that residues located on the "outer" (lipid-facing) surface of the transmembrane (TM) receptor core are critically involved in ...

Multiple Residues in the Second Extracellular Loop Are Critical for M3 Muscarinic Acetylcholine Receptor Activation [PDF]

open access: yes, 2007
Recent studies suggest that the second extracellular loop (o2 loop) of bovine rhodopsin and other class I G protein-coupled receptors (GPCRs) targeted by biogenic amine ligands folds deeply into the transmembrane receptor core where the binding of cis ...
