  • Title: Effect of denervation on the synthesis of ribonucleic acid and deoxyribonucleic acid in rat diaphragm muscle.
    Author: Manchester KL, Harris EJ.
    Journal: Biochem J; 1968 Jun; 108(2):177-83. PubMed ID: 5665882.
    Abstract:
    1. The effect of unilateral denervation of rat diaphragm muscle on its content of nucleic acids and their incorporation of precursors was investigated. 2. After denervation the paralysed hemidiaphragm hypertrophies and within 3 days its content of RNA increases considerably. The concentration of DNA/unit mass remains fairly constant. 3. During this period there is some increase in the rate of incorporation of [(14)C]adenine into RNA, whereas there is some diminution in the rate of incorporation of [(14)C]orotic acid. 4. Incorporation of [(14)C]adenine and [(3)H]thymidine into DNA is much increased in the paralysed tissue, reaching its maximum by about the third day, but returning to normal by the tenth. 5. The significance of these results in relation to the hypertrophy after denervation is discussed.
