Research Description
Jones' 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 mechanisms during exercise training. He is 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. It has been 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.
