Outline of Final Research Achievements

It is important to investigate the mechanisms of cell division and the regulation of energy consumption of cardiomyocyte for cardiovascular medicine. We identified Fam64a as an novel essential molecule for caudiomyocyte division. Fam64a was abundantly expressed in hypoxic fetal cardiomyocyte nuclei, but was sharply repressed by oxygen exposure, and also in postnatal cardiomyocytes. Fam64a knockdown inhibited and its overexpression enhanced the proliferation of cardiomyocytes. Non-degradable Fam64a mutant suggested that its optimum expression and subsequent degradation by anaphase-promoting complex/cyclosome before anaphase are required for cell division. Moreover, we revealed that short term triiodothyronine(T3) administration increased SERCA2 expression and decreased NCX1 expression but did not change cardiac contractility, resulting in energy-saving oxygen consumption for excitation-contraction coupling. Long term T3 administration decreased cardiac contractility and NCX activity.
