... of sarcoplasmic reticulum (SR) function. In intact myocytes EMD 57033 (1–10 µ mol/l) produced a concentration-dependent decrease in the amplitude of the Ca 2+ transient and prolonged its declining phase, but had no effect on the rise time. In skinned myocytes, the amplitude of spontaneous Ca 2+ release from...

...Hidetoshi HASHIDA; Mareomi HAMADA; Kunio HIWADA This study was designed to clarify whether gene expression in the cardiac sarcoplasmic reticulum [sarcoplasmic reticulum Ca 2+ -ATPase (SERCA), phospholamban, ryanodine receptor and calsequestrin] changes in accordance with left ventricular functional...

... [1,25-(OH) 2 D,]. 2. The uptake of calcium into the isolated sarcoplasmic reticulum from mixed striated quadriceps muscle, and the amount of troponin C (the calcium-binding component of the troponin complex) in relation to other proteins from the same muscle, were measured. 3. In muscle from animals...
