Prof. Manuel Mayr: A Multi-omics Approach to Cardiovascular Disease
Cardiovascular disease (CVD) results from a complex interplay of genes and environmental factors. A clear picture of how these different factors impact on individuals is yet to emerge. Lipid abnormalities account for over 60% of the population attributable risk for myocardial infarction and are the most important single target for prevention, along with blood pressure lowering and smoking cessation. Traditionally, research focused predominantly on lipid classes, such as cholesterol and triglycerides, while ignoring their inherent complexity of lipid speciation and differential associations with CVD. Likewise, lipoproteins were mostly defined in terms of their separation by physical properties which does not always correspond to their function. Among apolipoproteins, the main focus has been on apoB-100 and apo-A1. There are likely targets beyond these measurements that can inform on CVD risk. My group uses mass spectrometry-based proteomics to integrate biological information in disease-specific networks for CVD. Using mass spectrometry, we recently demonstrated that resolving the complexity of apolipoproteins improves CVD risk prediction. Notably, plasma data are integrated with proteomics findings from human atherosclerotic plaques to advance our understanding how circulating biomarkers relate to lipid retention and vascular inflammation in CVD. By linking cutting-edge technologies to tissue biobanks and prospective, community-based studies, our aim is to demonstrate how a multi-omics approach can be used to advance our understanding of the pathophysiological mechanisms of CVD.
