Mitochondria are important modulators of Ca(2+) homeostasis. However, it is not clear if they modulate and participate in smooth muscle signaling and contraction. The aim of the present work was to investigate the role of mitochondria in Ca(2+) transients and contraction induced by metabotropic muscarinic receptor activation in rat gastric smooth muscle.

Testosterone (TES), other androgens and female sex steroids induce non-genomic rapid relaxing effects in airway smooth muscle (ASM). In guinea pig ASM, basal tension was relaxed by dehydroepiandroster...
Sinularin is an active compound isolated from the cultured soft coral Sinularia flexibilis. In this study, we investigated the effects of sinularin on two human gastric cancer cell lines, AGS and NCI-...
Increased osteopontin (OPN) expression in the heart, specifically in myocytes, associates with increased myocyte apoptosis and myocardial dysfunction. Recently, we provided evidence that OPN interacts...
To investigate headache score and accompanying symptoms during and after infusion of carbachol.
An association between insulin resistance and mitochondrial dysfunction has been observed in aging, T2D, and in offspring of patients with T2D. It remains to be determined whether pharmac...
The purpose of this study is to test if carbachol infusion induces headache in migraine subjects as well as intra- and extra-cerebral vasodilatation.

A synthetic methylprostaglandin E1 analog that reduces gastric acid secretion and enhances the gastric mucus-bicarbonate barrier. It is effective in the therapy of gastric ulcers and gives significant protection against NSAID-induced gastric mucosal damage. The drug also prevents cyclosporin A-induced damage to endocrine and exocrine pancreatic secretions. It shows a low order of acute toxicity and there is no evidence of embryotoxicity, fetotoxicity, teratogenicity, or mutagenicity in animal studies.
Artificially induced UTERINE CONTRACTION. Generally, LABOR, OBSTETRIC is induced with the intent to cause delivery of the fetus and termination of pregnancy.
Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.
Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.
A subclass of purinergic P2Y receptors that have a preference for ATP and ADP. The activated P2Y1 receptor signals through the G-PROTEIN-coupled activation of PHOSPHOLIPASE C and mobilization of intracellular CALCIUM.
