Isogenic human pluripotent stem cell disease models reveal actin binding Rho activating protein deficiency underlies the cardiac troponin T DK210 mutation-induced familial dilated cardiomyopathy I
Ontology highlight
ABSTRACT: The cTnT-DK210 DCM mice showed ABRA protein deficiency, sarcomeric disruption, and compromised heart contractility. Heart-specific expression of ABRA in cTnT-DK210 mice restored sarcomeric structures, reversed the disease progress, and rescued the DCM phenotypes. ABRA deficiency and compromised downstream serum response factor-regulated muscle gene expression play a key role in familial DCM caused by the cTnT-DK210 mutation. ABRA is a good therapeutic gene for cTnT-DK210-induced DCM and could be translated to other cTnT mutations-induced familial DCM.
