Induction of Oxidative Stress to Promote Angiogensis
Lisa Gould MD

Basic Research Grant
Regardless of etiology, a common feature of chronic wounds is tissue ischemia and its sequelae. This is compounded in elderly individuals who have poor tissue perfusion due to peripheral vascular disease or heart disease. Induction of angiogenesis in the ischemic wound bed is critical for tissue repair. Both hypoxia and hyperoxia have been shown to induce angiogenesis, yet the mechanism whereby these two opposing stimuli can produce the same result remains obscure. We will utilize the aortic ring assay to test the hypothesis that both hypoxia and hyperoxia induce oxidative stress, resulting in a series of molecular signals that promote angiogenesis. This ex vivo assay is well established in our laboratory and is well suited for studying the molecular mechanisms of angiogenesis. Upon completion of this proposal we will have identified the molecular pathway(s) used in redox sensitive signaling. Further resolution of the mechanisms of oxygen sensitive signal transduction will lead to strategies, such as gene therapy, to induce angiogenesis in the wound bed.
