Hope for Heart Patients: RNA Therapy May Help Hearts Heal Themselves

Researchers at Columbia University have developed a new RNA therapy that appears to help the heart repair itself after a heart attack. The therapy, delivered via a single injection, improved the heart's ability to protect and heal itself in animal experiments. The therapy is based on restoring the production of a hormone, atrial natriuretic peptide (ANP), which declines with age and is important for the regeneration of heart muscle cells. The new approach allows the body to produce the drug directly in the heart. Researchers believe this therapy could have applications for other conditions, such as kidney disease and high blood pressure, opening new avenues for regenerative medicine.
