Novel mRNA-based therapy shows promise in heart regeneration after heart attack

Heart attacks remain a leading cause of death and disability worldwide. The permanent loss of heart muscle cells—known as cardiomyocytes—and the heart's limited regenerative capacity often lead to chronic heart failure. Current treatment strategies manage symptoms but do not repair the underlying damage.

Now, researchers at the Lewis Katz School of Medicine at Temple University have identified a new strategy that may help repair damaged heart tissue by reactivating an important developmental gene.

In a study published in Theranostics, a multidisciplinary team led by Raj Kishore, Ph.D., Laura H. Carnell Professor, Vera J. Goodfriend Chair in Cardiovascular Research, Chair of Cardiovascular Sciences, and a member of the Aging + Cardiovascular Discovery Center at Temple, describes how a gene known as PSAT1, delivered through synthetic modified messenger RNA (modRNA), can stimulate heart muscle repair and improve cardiac function following heart attack.

The study represents a major step forward in the effort to develop regenerative therapies for ischemic heart disease.
