Regulation of myoplasmic Ca(2+) in genetically obese (ob/ob) mouse single skeletal muscle fibres.
Pflügers Archiv : European Journal of Physiology 2002 September
The present study examined whether calcium handling in skeletal muscle fibres from ob/ob mice was abnormal compared to normal mice. Simultaneous measurements of free myoplasmic calcium and force were made in mouse single intact muscle fibres at rest, during repetitive stimulation and for 30 min afterwards. Fibres were subjected to two bouts of intermittent tetanic contractions 1 h apart. The first bout consisted of 50 tetani only, while during the second bout stimulation was continued until force fell to 40% of control. During a bout of 50 repeated contractions, muscle fibres from ob/ob mice were unable to maintain basal calcium and tetanic calcium transients. During a second series of contractions, muscle fibres from ob/ob mice showed a marked improvement in calcium handling compared to the first series but still fatigued more rapidly than control fibres. It is concluded that calcium handling in skeletal muscle fibres from ob/ob mice is abnormal compared to fibres from normal mice and this contributes to premature fatigue.
