My laboratory is interested in developing neuroprotective agents targeting neurodegeneration associated with stroke and cerebrovascular diseases. We have previously shown that –(-)epicatechin, a polyphenolic compound found abundantly in dark chocolates, has neuroprotective properties and salvages dying neurons in the penumbra region of stroke, wherein cells are half dead and half alive and can be saved by timely intervention by targeting particular genes or molecules. To further delineate the mechanism of action of these potential neuroprotective agents, we are interested in evaluating how these compounds up-regulate antioxidant gene, Heme-oxygenase-1 (HO-1), which has been shown to provide neuroprotection in various ischemic models. We are also aware that HO1 is up-regulated by Nrf2, a transcription factor that has been shown to up-regulate a battery of antioxidant genes in stressful situations and strengthen defense mechanisms. Therefore, it is imperative to study the role of the HO1/Nrf2 pathway as a mechanism involved in the protection provided by these neuroprotective agents. To studying these novel compounds, we have developed in vivo [Middle Cerebral Artery Occlusion (t-MCAO); Permanent Distal Middle Cerebral Artery Occlusion (pMCAO); and Delayed Hippocampal Neuronal Death in global ischemia (BCCAO)] and in vitro [Oxygen-glucose deprivation (OGD); cell death models] working models of ischemia. These models simulate the conditions of human stroke and provide us alternatives to study the mechanism of stroke and test therapeutic potential of novel neuroprotective agents. These studies may provide a unique contribution for the treatment of stroke and ischemic brain injury and contribute to public health in the United States as well as globally.
