Gene therapy boosting GABARAPL1 reversed diabetic heart failure in mice and human heart tissue by enhancing glycophagy, a process that clears excess glycogen from heart cells.
Scientists reversed diabetic heart failure in mice and lab-grown human heart tissue using gene therapy that boosts the protein GABARAPL1, essential for a newly discovered process called glycophagy, which clears excess glycogen from heart cells.
The treatment restored heart function without affecting blood sugar or weight, improved heart relaxation in human cells, and showed stronger effects in female hearts.
Researchers say this targets the heart’s energy recycling directly, offering a new treatment path for diabetic heart disease.
The study was led by teams from the University of Auckland and University of Melbourne, with funding from organizations in New Zealand, Australia, the U.S., and Diabetes Australia.
La terapia génica que estimuló GABARAPL1 revirtió la insuficiencia cardíaca diabética en ratones y en el tejido cardíaco humano al mejorar la glucophagy, un proceso que elimina el exceso de glucógeno de las células cardíacas.
