Abstract
STUDIES on the process by which enlargement of the heart occurs1 2 3 4 have been aided by developments in molecular biology. Recent reviews in this journal have dealt with the information available on liver regeneration and compensatory growth of the kidney.5 , 6 As with the liver and the kidney, there is still a considerable lack of understanding of the molecular changes that occur during cardiac enlargement. Cardiac muscle is technically more difficult than liver to study in this respect because of the resistance of the tissue to fractionation, the preponderance of contractile proteins and the paucity of protein-synthesizing structures. Nevertheless, information has been . . .
