Investigating inherited cardiac pathologies using iPSC-derived cardiomyocytes generated from the patients' somatic cells.

Dilated Cardiodystrophinopathy caused by mutations in dystrophin (DYS) is a dilated cardiomyopathy (DCM) occurring in 70-100% of DYS patients, and is a major cause of death due to end-stage heart failure in Duchenne Muscular Dystrophy (DMD). Despite major advances in understanding DYS-DCM, to date there are no cures for DMD, except for heart failure medications, and therefore new therapeutic approaches are urgently required. Our working hypothesis is that any therapy of interest should be individually tailored according to the gene mutation and protein defect, and therefore has to be tested first in vitro in mutated cardiomyocytes from the affected individual. Accordingly, our goals are to: (1) generate an in vitro system for investigating the mechanisms of inherited cardiodystrophinopathies, using iPSC-derived cardiomyocytes (iPSC-CM) generated from the patients' somatic cells; (2) utilize mutated iPSC-CM to test the efficacy of existing and novel drugs and identify new therapeutic targets.
