(Nitric Oxide Synthetase, NCI Thesaurus)
This gene plays a regulatory role in smooth muscle contraction.
(NMU Gene, NCI Thesaurus)
This gene plays a role in cell-cell signaling, muscle contraction and synaptic transmission.
(NOS1 Gene, NCI Thesaurus)
Nimodipine inhibits the transmembrane influx of calcium ions in response to depolarization in smooth muscle cells, thereby inhibiting vascular smooth muscle contraction and inducing vasodilatation.
(Nimodipine, NCI Thesaurus)
