Regulation of force and shortening velocity in smooth muscle
Smooth muscle is characterised by high tension economy, low shortening velocity and regulation mainly by myosin light chain (MLC) phosphorylation. The aim of this study was to investigate regulation of force and maximal shortening velocity (Vmax) in smooth muscle. In intact muscle, activated with depolarisation, inhibition of force and rise in intracellular [Ca2+] ([Ca2+]i) by 2,3-butanedione mono
