The excitation-contraction coupling in skeletal muscle is modulated by nitric oxide via redox status modification of ryanodine receptor on sarcoplasmic reticulum during events that lead to muscle contraction.

Abstract
The excitation-contraction coupling in skeletal muscle is modulated by nitric oxide via redox status modification of ryanodine receptor on sarcoplasmic reticulum during events that lead to muscle contraction. We have synthesized a derivative of antilipidemic drug gemfibrozil, in which a NO-donor furoxan mojety is joined to the fibrate by an ester linkage. Aim of the present study is to determine if the NO released from the above compound is capable to influence the NO-sensible EC coupling steps in skeletal muscle and if this effect could be potentially utilised for physiopathological studies and pharmaceutical applications. To obtain this goal we decided to study some of the excitation-contraction mechanisms in the presence of NO-releasing derivative of gemfibrozil in skeletal muscle C2C12 cell line.File | Dimensione | Formato | |
