We previously demonstrated that 20(S)-ginsenoside Rg(3) (Rg(3)), one of the active components of Panax ginseng, non-competitively inhibits 5-HT(3A) receptor channel activity on extracellular side of the cell. Here, we sought to elucidate the molecular mechanisms underlying Rg(3)-induced 5-HT(3A) receptor regulation.
The aim of this study was to determine the effects of motilin on [Ca(2+)](i) regulation and its underlying molecular mechanism in cultured antral smooth muscle cells (ASMCs). Antral cells were isolated and cultured from neonatal rats, and then the [Ca(2+)](i)
Our previous studies indicated that Alzheimer's disease (AD) related amyloid beta peptide (Abeta) significantly altered muscarinic cholinergic receptor (mChR) signaling on the level of G protein regulated phospholipase C (PLC) leading to the lower formation of inositol-1,4,5-triphosphate (IP3) and diacylglycerol

We have previously reported that paraoxon, an organophosphate compound, at submicromolar concentrations effectively suppresses Ca2+ action potentials and modulates the activity of snail neurons. This effect was unrelated to acetylcholinesterase inhibition but was found to involve the direct or indirect

Calcium-mediated signalling is ubiquitous in both animals and plants. Changes in cytoplasmic free Ca(2+) concentration couple diverse arrays of stimuli to their specific responses, the specificity of the stimulus being determined by integrated actions between multiple Ca(2+) mobilization pathways. In
