Résumé

Cardiac hypertrophy compensates for increased biomechanical stress of the heart induced by prevalent cardiovascular pathologies but can result in cardiac failure if left untreated. We hypothesized that the tail-anchored protein dysferlin with multiple Ca To reveal the impact of the membrane fusion and repair protein dysferlin on TAT network stabilization and proliferation necessary for the hypertrophic growth of cardiomyocytes. Super-resolution light and electron microscopy of mouse cardiomyocytes identified a specific localization of dysferlin in a vesicular compartment in nanometric proximity to contact sites of the TAT network with the sarcoplasmic reticulum, a.k.a. junctional complexes for Ca Dysferlin represents a new molecular target in cardiac disease that protects the integrity of tubule-sarcoplasmic reticulum junctional complexes for regulated excitation-contraction coupling and controls TAT network reorganization and tubular membrane proliferation in cardiomyocyte hypertrophy induced by pressure overload.
