| Research Abstract |
Idiopathic cardiomyopathy (ICM) is heterogeneous myocardial disease associated with functional abnormalities of cardiomyocytes. The aim of this study was to investigate the novel molecular pathogenesis of ICM caused by the genetic abnormalities. As the results, it was identified that (1) mutations in genes encoding CARP and Fukutin are associated with dilated cardiomyopathy (DCM), and (2)ZASP/Cypher anchors PGM1 to Z-disc under conditions of stress and the impaired binding of PGM1 to ZASP/Cypher might be involved in the pathogenesis of DCM.
