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

Roche Funds Drug Discovery Projects at UC San Diego

The new UC San Diego-Roche Extending Innovation Network (EIN) program has been launched with selection of its first three research projects at the University of California, San Diego School of Medicine. The UC San Diego-Roche EIN program, which was formalized in June 2011, aims to accelerate the discovery of new drug therapies through research innovation at the interface of industry and academia. The program is slated to grow in the coming years as additional rounds of proposals are solicited. … Read the full story from the UCSD Newsroom
