This analysis reveals oxidoreductases activity differences in cardiac and skeletal muscle of scorpionfish, suggesting age-related adaptations to hypoxia.
The oxidoreductases activity (MDH, 1.1.1.37; LDH, 1.1.1.27; catalase, 1.11.1.6) was studied in the white, red muscles and myocardium (heart atrium, ventricle) of adult and juvenile Linnaeus, 1758 as a preadapted to hypoxia species. Tissue and age differences in the magnitude and ratio of oxidoreductases activity were established. A similar value of MDH activity was found in the following tissue pairs: in the atrium and red muscles of adult, as well as in the atrium and white muscles, ventricle and red muscles of juvenile scorpionfish. Catalase activity was associated with the physiological activity of skeletal muscle and increased with the age of the scorpionfish. The commonality of the energy metabolism pathways in the myocardium and skeletal muscles was determined by an age-dependent increase in the efficiency of the heart performance which associated with the initial “anaerobization” of the myocardium as a protective mechanism during O deficiency.
