Knockout of Na+/Ca2+ exchanger in smooth muscle attenuates vasoconstriction and L-type Ca2+ channel current and lowers blood pressure.
Mice with smooth muscle (SM)-specific knockout of Na(+)/Ca(2+) exchanger type-1 (NCX1(SM-/-)) and the NCX inhibitor, SEA0400, were used to study the physiological role of NCX1 in mouse mesenteric arteries. NCX1 protein expression was greatly reduced in arteries from NCX1(SM-/-) mice generated with Cre recombinase. Mean blood pressure (BP) was 6-10 mmHg lower in NCX1(SM-/-) mice than in wild-typ...

متن کاملConditional knockout of smooth muscle sodium calcium exchanger type‐1 lowers blood pressure and attenuates Angiotensin II‐salt hypertension
The functions of smooth muscle sodium calcium exchanger (NCX) in the vasculature are controversial and poorly understood. To determine the possible roles of NCX in the vascular phenotype and function, we developed a novel mouse model (SM-NCX1 KO) in which the smooth muscle-specific NCX type-1 (NCX1) was conditionally knocked out using tamoxifen-inducible Cre-loxP recombination technique. SM-NCX...

Smooth muscle cells of seminal vesicle exhibit excitatcry junction patential on nerve stimulation and can fire evoked) action potential (1). However) the type of ion channels that underlie this electrical activity have not been described. I have investigated the type and pharmacology of ion channel in freshly isolated smooth muscle cells from the guinea-pig seminal vesicle using whole-cell patc...
