Gene Information

human ... CHRM3(1131)

Application

p-Fluorohexahydro-sila-difenidol hydrochloride (pFHHSid) has been used:
  • as the M3/muscarinic acetylcholine receptor antagonist to study its involvement in carbachol induced Egr-1 biosynthesis using human neuroblastoma cells
  • as M3 receptor antagonist to test its involvement on N,N-diethyl-m-toluamide (DEET)-induced angiogenesis in human umbilical venous endothelial cells (HUVEC)
  • in a study to examine the role of aclidinium on human fibroblast to myofibroblast

Biochem/physiol Actions

High affinity M3 muscarinic acetylcholine receptor antagonist.

The Fallopian tubes are sparsely innervated with cholinergic nerve fibers. Acetylcholine is released from these nerves and contracts the smooth muscles of the tubes. The aim of our study was to investigate the effect of acetylcholine on the isthmic segment

Fibroblast to myofibroblast transition is believed to contribute to airway remodelling in lung diseases such as asthma and chronic obstructive pulmonary disease. This study examines the role of aclidinium, a new long-acting muscarinic antagonist, on human fibroblast to myofibroblast transition.

The effect of the cholinomimetic agent, bethanechol on macroscopic membrane currents was studied in dispersed cat atrial myocytes, using the whole-cell patch-clamp technique. Bethanechol activated an inward rectifying potassium current similar to I(K(ACh)), and a delayed rectifying-like outward current, similar

Carbachol-mediated activation of type M(3) muscarinic acetylcholine receptors induces the biosynthesis of the transcription factor Egr-1 in human SH-SY5Y neuroblastoma cells involving an activation of extracellular signal-regulated protein kinase. Carbachol triggered the phosphorylation of the ternary complex factor Elk-1, a

Most colon cancers overexpress M3 muscarinic receptors (M3R), and post-M3R signaling stimulates human colon cancer cell proliferation. Acetylcholine (ACh), a muscarinic receptor ligand traditionally regarded as a neurotransmitter, may be produced by nonneuronal cells. We hypothesized that ACh release by
