At the Icahn Institute for Genomics and Multiscale Biology, we use systems genetics that combines epidemiology, genomics, proteomics, and metabolomics to study cardiovascular diseases (CVDs). Our goal is to better understand the molecular landscape of regulatory networks acting within and across metabolic and vascular tissues that causes CVD in humans.
CVD is the leading cause of death, responsible for nearly half of all mortalities in the US and worldwide. Atherosclerotic lesions in larger blood vessels (arteries) are the main cause of CVD leading to myocardial infarction (heart attack) or stroke.
Today, CVD can only be partially prevented by targeting CVD risk factors, such as high levels of bad cholesterol. We focus on trying to improve prevention of CVD by identifying early molecular diagnostics of people at risk for heart attack or stroke as well as therapies directly targeting atherosclerosis. A key resource for our work, generated in collaboration with Tart University Hospital in Estonia, is our human multi-tissue DNA and RNA dataset and biobank, named STARNET. This work is led by the Björkegren laboratory in close collaboration with the Schadt Laboratory.
