Research Interests
My research program currently focuses on
mechanisms of membrane regulation and vascular
smooth muscle function leading to abnormalities
associated with hyper- lipidemia as well as
adaptative echanisms during exercise training.
We are studying mechanisms of adenosine
transport and adenosine regulation of smooth
muscle responses to acute metabolic depression
in porcine coronary arteries. These studies have shown a novel mechanism by which smooth muscle generated adenosine has an autocoid
function during an ischemic response. Mechanisms being pursued relate to adenosine
interaction with receptors and subsequent cellular events causing relaxation; as well as
adenosine interaction with a target enzyme, AMP kinase, which in turn regulates both cell
metabolism and functional responses. We have observed that exercise training may alter the
sensitivity of vascular smooth muscle in the porcine coronary arteries especially in males.
Gender studies have also been initiated. These studies involve close collaboration with
members of a program project team on exercise physiology, the Center for Gender
Physiology and Environmental Adaptation, and the Center for Diabetes and Cardiovascular
Health. Methods utilize microfluorometry of calcium probes, digital image analyses, patch
clamp techniques, radio isotopes fluxes, contractile responses, phosphor-image analyses,
and biochemical and immuno-measures of AMP kinase.
