  • Title: Energy dependence of cytosolic enzyme efflux from rat skeletal muscle.
    Author: West-Jordan JA, Martin PA, Abraham RJ, Edwards RH, Jackson MJ.
    Journal: Clin Chim Acta; 1990 Aug 15; 189(2):163-72. PubMed ID: 2118840.
    Abstract:
    (1) A recirculating isolated superfused skeletal muscle preparation has been developed for the study of rat soleus muscles at physiological temperature using 31P Nuclear Magnetic Resonance (NMR). (2) This system has been used to study intracellular muscle high energy phosphate content and pH during experimental damage to the muscle induced by 2,4-dinitrophenol, deoxycholate and the calcium ionophore, A23187. (3) Results indicate that release of intracellular cytosolic enzymes from damaged skeletal muscle may be induced by phosphocreatine (PCr) and adenosine trisphosphate (ATP) depletion, but under certain circumstances intracellular enzymes can be released from skeletal muscle without any fall in muscle PCr or ATP content.
