Physiological and pathological effects of oxidation on contractile function in skeletal muscle

点击翻译按钮获取中文摘要

Reactive oxygen molecules generated within muscle fibres in normal exercise and in pathological conditions, greatly affect muscle function by altering the responsiveness of the contractile proteins. This study investigates how various oxidative stresses affect particular reactive sites on key proteins controlling muscle contraction. The findings should identify key molecular changes involved in normal activity and the role oxidation plays in chronic muscle weakness in particular conditions.
