Chicco Lab

The Chicco laboratory investigates the roles of polyunsaturated fatty acid metabolism and mitochondrial function in cardiometabolic health and disease. Lab members conduct basic, integrative and translational studies utilizing animal models of human disease, dietary and pharmacological interventions, and genetic gain/loss-of-function approaches targeting enzymatic regulators of lipid metabolism. These studies are complimented by collaborative projects with scientists at CSU, around the US and abroad investigating metabolic responses to physiological and pathological stress in humans, laboratory animals and non-model organisms.

Polyunsaturated fatty acid metabolism in cardiometabolic disease

Polyunsaturated fatty acids (PUFAs) play diverse roles in cell physiology that impact the function of all major body systems in health and disease. Studies in our lab seek to better understand the interaction of dietary PUFA intake and their endogenous metabolism on the development of heart disease and diabetes/insulin resistance.

Metabolic aspects of early embryo development and fetal programming

Accumulating evidence indicates that metabolic changes in the ovarian follicle, developing embryo, and intrauterine environment impact reproductive potential, fetal health and offspring disease risk. A primary focus of collaborative studies in our lab is to understand the influence of maternal aging and diet on follicular, embryo, and fetal metabolism in equine, ovine, and murine models.

Mitochondrial Physiology in Health and Disease

Mitochondria play essential roles in cellular energy metabolism, redox balance, and cell fate that regulate organismal responses to physiological and pathogenic stress. Research in our lab investigates how mitochondrial metabolism influences successful adaptation to evolutionary and environmental pressures and the development of human diseases.

Cardiovascular effects of space radiation

Astronauts on long duration missions beyond low Earth orbit will be confronted with a unique radiation environment that increase risks for adverse health effects, including cancer and cardiovascular disease. Studies in our lab in collaboration with Dr. Michael Weil at CSU seek to understand the cardiovascular impacts of simulated space radiation exposure.
