Researchers Discover Protein’s Pivotal Role in Heart Failure

Better understanding of molecular mechanism could lead to new drug targets —

Researchers at the University of California, San Diego School of Medicine have identified a key piece in the complex molecular puzzle underlying heart failure – a serious and sometimes life-threatening disorder affecting more than 5 million Americans.

In a study published in the March 5 online issue of Cell Reports, Xiang-Dong Fu, PhD, and colleagues explored the heart’s progression from initial weakening to heart failure, and found that a protein, known as RBFox2, plays a critical role in this process. … Read the full story from the UC San Diego Newsroom
