Researchers at Brigham and Women’s Hospital have found two new potential drug targets for treating arterial diseases such as atherosclerosis. By using proteomics to screen a vast number of molecules, the researchers identified PARP9 and PARP14 – two members of the PARP family of proteins – as regulators of macrophage activation, which has been linked to arterial disease by systems biology.

Though the mechanisms that activate macrophages, a type of digestive white blood cell that targets foreign cells, remain incompletely understood, previous research shows that macrophages play an important role in the development of atherosclerosis and its thrombotic complications. Masanori Aikawa, MD, PhD, director of the Center for Interdisciplinary Cardiovascular Sciences (CICS) at the Brigham, his research fellow Hiroshi Iwata, MD, PhD, and colleagues studied atherosclerosis on the protein-level to determine which molecules were most involved in the regulation of macrophages.

Once Aikawa and his colleagues narrowed down their search to these two proteins, they silenced each gene in cultured macrophages and found that tamping down PARP14 increased macrophage activation while tamping down PARP9 had the opposite effect.

Aikawa founded CICS and hopes that this hypothesis-generating method can be used to streamline the lengthy process of drug development. Aikawa and CICS are using a more systematic approach which hinges on network analysis; this analysis predicts which pathways are most likely to control their studied effect so that they can prioritize these pathways. Ideally, this process would take a fraction of the time in comparison to searching through each individual pathway unaware of their likelihood of affecting their studied effect.

Aikawa and his colleagues plan to augment these findings to develop targeted therapeutics for atherosclerosis and other diseases.

“Macrophage activation plays a role in not only vascular disorders but also various inflammatory and autoimmune diseases,” said Aikawa. “These results could provide important information about the mechanisms of these diseases and help to develop much needed new therapeutics.”
