HEK293 cells have been used extensively to generate stable cell lines to study G protein-coupled receptors, such as muscarinic acetylcholine receptors (mAChRs). The activation of M1 mAChRs in various cell types in vitro has been shown to be protective. To further investigate M1 mAChR-mediated cell survival, we generated stable HEK293 cell-lines expressing the human M1 mAChR. M1 mAChRs were effi...

The maxillary first and second molars (M1 and M2) in the Japanese shrew mole, Urotrichus talpoides, were investigated using an odontometrical approach. The mesiodistal crown diameter was larger in M1 than in M2, while the buccolingual diameter of M1 was nearly equal to that of M2. M2 was more compressed mesiodistally than M1. M1 had a large distal triangle on the stylar shelf. The mesial triang...

Identification of optimal treatment strategies to improve recovery is limited by the incomplete understanding of the neurobiological principles of recovery. Motor cortex (M1) reorganization of the lesioned hemisphere (ipsilesional M1) plays a major role in post-stroke motor recovery and is a primary target for rehabilitation therapy. Reorganization of M1 in the hemisphere contralateral to the s...

background: genetic polymorphisms of cytochrome p450 in humans are the main cause of differences in the metabolism. the allele and genotype frequencies of cyp2c19 and cyp2c9 have been studied in some iranian populations. the aim of present study was to examine the frequencies of cyp2c18m1, and cyp2c18m2, alleles in the mazandarani ethnic group among iranian population. materials and methods: in...

We used retrograde transneuronal transport of herpes simplex virus type 1 to map the origin of cerebellar and basal ganglia "projections" to leg, arm, and face areas of the primary motor cortex (M1). Four to five days after virus injections into M1, we observed many densely labeled neurons in localized regions of the output nuclei of the cerebellum and basal ganglia. The largest numbers of thes...

Background It is still unclear which underlying mechanisms are involved in cognitive deficits of psychotic disorders. Pro-cognitive effects of muscarinic M1 receptor agonists suggest alterations in M1 receptor functioning may modulate these symptoms. Post mortem studies in patients with schizophrenia have shown significantly reduced M1 receptor expression rates in the dorsolateral prefrontal co...

An eight-step procedure has been devised for the preparation of homogeneous rabbit reticulocyte IF-M1. Molecular weight determinations based on IF-M1 activity (gel filtration and sucrose density gradient sedimentation) and based on IF-M1 protein (low speed equilibrium sedimentation and sodium dodecyl sulfate gel electrophoresis) indicate that IF-M1 is active as a single polypeptide chain of 65,...

Plasmodium falciparum alanine M1-aminopeptidase (PfA-M1) is a validated target for anti-malarial drug development. Presence of significant similarity between PfA-M1 and human M1-aminopeptidases, particularly within regions of enzyme active site leads to problem of non-specificity and off-target binding for known aminopeptidase inhibitors. Molecular docking based in silico screening approach for...

In this work we compute the Chen–Ruan cohomology of M1,n and M1,n, and its algebraic counterpart: the stringy Chow ring. We suggest a definition for a Chen–Ruan tautological ring in genus 1, which is both a subring of the Chen–Ruan cohomology and of the stringy Chow ring.
