Scientists at Sanford Burnham Prebys and Salk Institute for Biological Studies have uncovered a new role for a protein known for its role in the brain helping control feelings of hunger or satiety, as well as in the liver to aid the body in maintaining a balance of energy during fasting. The new study shows that this protein also supports the maintenance of heart structure and function, but when it is overactive it causes thickening of the heart muscle, which is associated with heart disease.

There’s still much to learn about how doxorubicin, a 50-year-old chemotherapy drug, causes its most concerning side effects. While responsible for saving many lives, this treatment sometimes causes cardiac damage that stiffens the heart and puts a subset of patients at risk for future heart failure. To better understand and potentially control such complications, Tufts University School of Medicine and Tufts Graduate School of Biomedical Sciences researchers have isolated the immune cells that become overactive when patients take doxorubicin.
