Previous studies demonstrated that maintenance of steady-state myogenic tone requires Ca(2+)-dependent myosin phosphorylation. The present studies furthered these observations by examining temporal relationships among Ca(2+), myosin phosphorylation and vessel diameter during acute increases in intraluminal pressure and norepinephrine stimulation. Rat cremaster muscle arterioles were cannulated and loaded with the Ca(2+)-sensitive indicator fura-2. The extent of myosin phosphorylation was… CONTINUE READING
