Cardiovascular disease is the leading cause of mortality in our country, and the obesity epidemic has amplified this public health problem. Our research focuses on cellular interactions and signaling and molecular mechanisms that impact cardiovascular disease.
In particular, we are interested in cells of the vessel wall and the surrounding perivascular adipose tissue (PVAT). The blood vessel and surrounding adipose tissue form a local vascular microenvironment that regulates susceptibility to vascular disease.
To study these interactions, we are identifying protein signatures of PVAT in human donors with different levels of cardiovascular disease, and also using mouse models of obesity and vascular disease. Conversely, our mouse models also allow us to evaluate PVAT in the context of anti-aging dietary conditions, such as methionine restriction or calorie restriction. Using these models, we are studying adipose progenitor cell characteristics, differentiation capacity, PVAT phenotype, and effects on vascular physiology.
Our laboratory also runs our institutional Mouse Genome Modification Resource and develops mouse models of human disease using CRISPR/Cas techniques and traditional transgenic microinjection procedures. We perform gene/protein analysis and develop research plans for targeting, as well as develop molecular reagents, perform microinjection, and establish and perform initial genotyping. Other services include a mouse germplasm cryopreservation program and a re-derivation program.
