HDAC6 modulates myofibril stiffness and diastolic function of the heart
Abstract Passive stiffness of the heart is determined largely by extracellular matrix and titin, which functions as a molecular spring within sarcomeres. Titin stiffening is associated with the development of diastolic dysfunction (DD), while augmented titin compliance appears to impair systolic performance in dilated cardiomyopathy. We found that myofibril stiffness was elevated in mice lacking histone deacetylase 6 (HDAC6).
Maturation of Pluripotent Stem Cell-Derived Cardiomyocytes Enables Modeling of Human Hypertrophic Cardiomyopathy
Highlights • Standard (glucose) cultured hiPSC-CMs demonstrate a blunted hypertrophic response • A maturation method induces hiPSC-CM maturation and suppresses HIF1A expression • Mature hiPSC-CMs demonstrate improved sarcomeric morphology and contractility • Mature hiPSC-CMs respond to agonist- or mutation-induced hypertrophy Summary Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) are a powerful platform for biomedical research.
