We use a variety of animal models, isotopic techniques and
analytical methods that allow us to study metabolism from gene to
the whole organism. In many of our studies we use physical
exercise, insulin-stimulation or diet to perturb metabolic fuel
systems. The research we undertake is not only critical to a basic
understanding of fuel metabolism but also has important
implications to diabetes and heart disease. Possible research
projects include studies of:
a. site-specific (extracellular glucose delivery, glucose
transport, glucose phosphorylation) regulation of muscle glucose
uptake in normal physiology, in insulin resistant states induced by
high fat feeding and in insulin sensitive states induced by
physical exercise.
b. roles of insulin and glucagon in regulation of hepatic glucose
metabolism during and after exercise.
c. integrated control of glucose and fat metabolism in health and
disease.
d. central role of energy sensors (AMP kinase, Sirtuins) in control
of intra- and interorgan fuel fluxes.
