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.

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 ...

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]

, 1992
We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

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 ...

Blockage of Cholinergic Signaling via Muscarinic Acetylcholine Receptor 3 Inhibits Tumor Growth in Human Colorectal Adenocarcinoma

Cancers, 2021
Simple Summary Darifenacin is a selective muscarinic acetylcholine receptor 3 (M3R) antagonist in clinical use for benign bladder disorders. Here, the effects of M3R blockage by darifenacin on human colon adenocarcinoma cells are analyzed in vitro and in

Novel aspects of cholinergic regulation of colonic ion transport [PDF]

, 2015
Nicotinic receptors are not only expressed by excitable tissues, but have been identified in various epithelia. One aim of this study was to investigate the expression of nicotinic receptors and their involvement in the regulation of ion transport across

Body Biofluids for Minimally‐Invasive Diagnostics: Insights, Challenges, Emerging Technologies, and Clinical Potential

Advanced Healthcare Materials, EarlyView.
Recent advances in diagnostics have accelerated the development of miniaturized wearable technologies for the continuous monitoring of diseases. This paradigm is shifting healthcare away from invasive, centralized blood tests toward decentralized monitoring, using alternative body biofluids.

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 ...

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

, 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 ...

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.
