Molecular Cloning of m3 Muscarinic Acetylcholine Receptor in Rat Iris.

Journal of Smooth Muscle Research, 1998
Muscarinic receptor subtypes that involved in cholinergic responses in rat iris were identified by reverse transcription-polymerase chain reaction (RT-PCR) analysis. mRNAs encoding m2, m3, and m4 subtypes were abundantly expressed in iris, whereas m1 and m5 subtypes were not detected.

Inhibition of cholinergic potentiation of insulin secretion from pancreatic islets by chronic elevation of glucose and fatty acids: Protection by casein kinase 2 inhibitor

Molecular Metabolism, 2017
Objectives: Chronic hyperlipidemia and hyperglycemia are characteristic features of type 2 diabetes (T2DM) that are thought to cause or contribute to β-cell dysfunction by “glucolipotoxicity.” Previously we have shown that acute treatment of pancreatic ...

Evidence for Respiratory Neuromodulator Interdependence after Cholinergic Disruption in the Ventral Respiratory Column [PDF]

, 2015
Reverse dialysis of the muscarinic receptor antagonist, atropine (ATR, 50 mM), into the pre-Bötzinger Complex region of the ventral respiratory column (VRC) of awake and sleeping goats increases breathing frequency and serotonin (5-HT), substance P (SP),

Molecular Modeling of the M3 Acetylcholine Muscarinic Receptor and Its Binding Site [PDF]

Journal of Biomedicine and Biotechnology, 2012
The present study reports the results of a combined computational and site mutagenesis study designed to provide new insights into the orthosteric binding site of the human M3 muscarinic acetylcholine receptor. For this purpose a three-dimensional structure of the receptor at atomic resolution was built by homology modeling, using the crystallographic ...

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

Journal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...

Muscarinic receptor activation in colon cancer selectively augments pro-proliferative microRNA-21, microRNA-221 and microRNA-222 expression.

PLoS ONE, 2022
Overexpression of M3 subtype muscarinic receptors (M3R) hastens colon cancer progression. As microRNA (miRNA) expression is commonly dysregulated in cancer, we used microarrays to examine miRNA profiles in muscarinic receptor agonist-treated human colon ...

Contrary effects of the gut metabolites deoxycholate and butyrate on the acetylcholine-evoked calcium response in an enteroendocrine cell model

Endocrine and Metabolic Science
The interaction of nutrients and bacterial-derived products and their enteroendocrine effects are still enigmatic. We used the human enteroendocrine tumour cell line P-STS isolated from the terminal ileum as cellular sentinel.

Deconvolution of complex G protein-coupled receptor signaling in live cells using dynamic mass redistribution measurements [PDF]

, 2010
Label-free biosensor technology based on dynamic mass redistribution (DMR) of cellular constituents promises to translate GPCR signaling into complex optical 'fingerprints' in real time in living cells.

Krisanaklan Reduces Intestinal Anion and Fluid Secretion Through Inhibition of Na+/K+‐ATPase and K+ Channel Activity

Annals of the New York Academy of Sciences, EarlyView.
Krisanaklan reduces CFTR‐dependent intestinal chloride and fluid secretion by inhibiting the Na+,K+‐ATPase and K+ channels in epithelial cells. Consequently, this natural, plant‐derived product may limit secretory diarrhea caused by a diverse array of microbial pathogens. However, by dissipating the transmembrane Na+ gradient, Krisanaklan also inhibits

Expression Profiles of Neuropeptides, Neurotransmitters, and Their Receptors in Human Keratocytes In Vitro and In Situ. [PDF]

PLoS ONE, 2015
Keratocytes, the quiescent cells of the corneal stroma, play a crucial role in corneal wound healing. Neuropeptides and neurotransmitters are usually associated with neuronal signaling, but have recently been shown to be produced also by non-neuronal ...
