Dr. Steve Lim, assistant professor of at the 天美影视传媒 College of Medicine, recently was awarded a $1.52 million four-year grant from the National Institutes of Health (NIH) to study cell signaling that contributes to atherosclerosis, a chronic vascular inflammatory disease.

The Research Project Grant, or R01 grant, is the original and historically oldest grant mechanism used by NIH. The R01 provides support for health-related research and development based on the mission of the NIH. This is Lim鈥檚 first R01 grant, which follows up on early stage funding from the American Heart Association.

鈥淭his award will allow us to investigate the detailed mechanisms of how focal adhesion kinase (FAK) regulates the vessel wall response to blood flow and inflammation during atherosclerosis,鈥 Lim said.

Atherosclerosis is caused by sustained activation of nuclear factor-kB (NF-kB), a pro-inflammatory transcription factor that drives pro-inflammatory gene expression. Through his research, Lim found that FAK inhibition blocks sustained NF-kB activity, thus reducing vascular inflammation in atherosclerosis.

鈥淭he goal of our study is to better understand the relationship between FAK and NF-kB in atherosclerosis, in the hope of identifying new therapeutic options,鈥 Lim said. 鈥淢illions of people are affected by atherosclerosis in the United States, and it is the underlying problem in most cardiovascular diseases.鈥

Preventative approaches to reduce conventional risks 鈥 such as drugs that lower cholesterol and blood pressure 鈥 help slow down the progression of atherosclerosis, but do not eradicate the abnormal vessel wall response to environmental factors that drive atherosclerosis. As an 鈥渁nti-inflammatory鈥 therapy for atherosclerosis remains elusive, Lim鈥檚 research into FAK-mediated inflammation during atherosclerosis is considered to have high potential in finding a new therapeutic target.

鈥淭he research supported by this grant could advance current atherosclerosis therapies from preventative to treatable,鈥 Lim said. 鈥淎 FAK inhibitor that stops atherosclerosis progression 鈥 as opposed to merely delaying it 鈥 would be very beneficial to patients.鈥

Lim said the grant will help to establish his research program, expand the research team and upgrade the quality of the current research.

He gave special thanks to his fourth-year graduate student, James Murphy, for his work on the grant. 鈥淭his R01 grant expands upon James鈥 graduate project, in which he seeks to find the molecular mechanism of FAK mediated NF-kB regulation in the vascular wall.鈥

Lim鈥檚 collaborative research team is comprised of USA College of Medicine researchers Dr. Richard Honkanen and Dr. Robert Barrington; Dr. Hanjoong Jo at Emory University; and Dr. Yabing Chen at the University of Alabama at Birmingham.
