flag Columbia researchers created a minimally invasive RNA therapy that helps hearts repair after a heart attack by reprogramming muscle to produce heart-regenerating proteins, showing promise in animal studies.

flag A Columbia University-led team has developed an RNA therapy that boosts the heart’s natural repair after a heart attack using a single injection. flag The treatment reprograms skeletal muscle to produce pro-ANP, a precursor activated into atrial natriuretic peptide (ANP) by the heart’s abundant Corin enzyme. flag In animal studies, it reduced scarring, improved heart function, and promoted blood vessel growth—mimicking newborns’ regenerative ability. flag Unlike invasive procedures, it’s minimally invasive, affordable, and targets the heart specifically. flag Published in Science on March 5, 2026, the approach offers a promising new path for treating heart damage, pending further human trials.
