Obesity represents a serious public health burden. Obese individuals experience increased risk of cardiovascular and metabolic cardiometabolic disease, including insulin diabetes, resistance, hypertension, and dyslipidemia. Obesity and obesity-associated cardiometabolic dysfunction are significant contributors to morbidity and mortality in Veterans. This indicates that obesity and cardiometabolic dysfunction are complex and multifactorial, and suggests that there are additional factors that contribute to the pathogenesis of obesity and its associated cardiometabolic risk that have been discovered. Moreover, some of the pharmacologic therapies for obesity can have adverse cardiovascular effects. Thus, it is crucial to improve the understanding of the multiple pathways contributing to the pathogenesis of obesity and obesity-associated cardiometabolic risk, including the identification of novel relevant pathways, in order to develop more effective treatments for these diseases. The proposed work will form a foundation for future high-impact studies of mechanisms for adiposity and cardiometabolic disease.
