      Lorén, Christina E.; Dahl, Christen Peder; Do, Lan; Almaas, Vibeke; Geiran, Odd; Mörner, Stellan; Hellman, Urban (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-29)
      During the development of hypertrophic cardiomyopathy, the heart returns to fetal energy metabolism where cells utilize more glucose instead of fatty acids as a source of energy. Metabolism of glucose can increase synthesis of the extracellular glycosaminoglycan hyaluronan, which has been shown to be involved in the development of cardiac hypertrophy and fibrosis. The aim of this study was to ...
