Gastrointestinal function regulation by nitrergic efferent nerves.
Gastrointestinal (GI) smooth muscle responses to stimulation of the nonadrenergic noncholinergic inhibitory nerves have been suggested to be mediated by polypeptides, ATP, or another unidentified neurotransmitter. The discovery of nitric-oxide (NO) synthase inhibitors greatly contributed to our understanding of mechanisms involved in these responses, leading to the novel hypothesis that NO, an ...
متن کاملMicroRNAs Dynamically Remodel Gastrointestinal Smooth Muscle Cells
Smooth muscle cells (SMCs) express a unique set of microRNAs (miRNAs) which regulate and maintain the differentiation state of SMCs. The goal of this study was to investigate the role of miRNAs during the development of gastrointestinal (GI) SMCs in a transgenic animal model. We generated SMC-specific Dicer null animals that express the reporter, green fluorescence protein, in a SMC-specific ma...
متن کاملSignal-transduction pathways that regulate smooth muscle function. II. Receptor-ion channel coupling mechanisms in gastrointestinal smooth muscle.
Regulation of membrane ion channels by second messengers is an important mechanism by which gastrointestinal smooth muscle excitability is controlled. Receptor-mediated phosphorylation of Ca(2+) channels has been known for some time; however, recent findings indicate that these channels may also modulate intracellular signaling. The plasmalemma ion channels may also function as a point of conve...
متن کاملNitrergic relaxation of gastrointestinal smooth muscle: role of interstitial cells of Cajal and smooth muscle cells
Background The signaling molecule nitric oxide (NO) is known to activate the enzyme NO-sensitive guanylyl cyclase (NOGC). By generation of the intracellular second messenger cGMP NO-GC regulates many physiological processes. In the gastrointestinal (GI) tract nitrergic neurons are part of the enteric nervous system which regulates GI motility. In addition, interstitial cells of Cajal (ICC) are ...
متن کاملShort Communication Filament Position in Fish Gills Is Influenced by a Smooth Muscle Innervated by Adrenergic Nerves
The two rows of filaments on fish gill arches are arranged in the respiratory water current to maintain a continuous 'gill curtain'. The position of the filaments is controlled mainly by striated adductor muscles, which can draw together the filaments, and also by the elasticity of the cartilaginous filamental skeleton (gill rods) which tends to keep the filaments extended in water. In addition...
