Hypoxia is characterized by an inadequate oxygen supply to the tissues in
proportion to their metabolic needs, and is a primary factor in traumatic CNS
injury, strokes, cardiopulmonary diseases, and obstructive sleep apnea. The
cAMP-dependent...
Pancreatic beta cells are extremely vulnerable to the destruction of Reactive Oxygen Species (ROS). In both type 1 and type 2 diabetes ROS are involved in the loss of U+000DF-cells. We hypothesized that the deficiency in ROS detoxifying system of...
Pancreatic beta cells are extremely vulnerable to destruction by Reactive Oxygen Species (ROS). In type 1 diabetes and islet transplantation ROS are thought to be involved in the loss of beta cells. To test the role of antioxidant in islet...
Sulforaphane (SFN), an isothiocyanate found in cruciferous vegetables, is known to confer antioxidant protection in vivo. Rather than directly reacting with free radicals, however, SFN works by inducing Nrf2, a transcription factor that binds to...
This thesis is divided into two parts below. Part I Adriamycin (ADR) can produce nephrotoxicity in rodents. The underlying mechanism may relate to ADR induced oxidative stress. In this study, we used transgenic mice (NMT3), which over-expressed the...
Oxygen is critical to aerobic metabolism, but hyperoxia is cytostatic and cytocidal. The precise mechanisms involved in hyperoxic cell injury remain incompletely understood although there is substantial support for the possibility that hyperoxia...
The lipid aldehydes, 4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are reactive α,β-unsaturated aldehydes generated during the peroxidation of lipids and are implicated in the pathogenesis of several oxidative-stress mediated diseases,...
The chaperone heat shock protein 90 (Hsp90) regulates physiologically and
pathological cellular processes, by binding and stabilizing kinases involved in basal
cellular functions and in cellular responses to stress, respectively. I hypothesize...
Pancreatic islet transplantation is a very promising treatment for type I diabetes. Many clinical trials have failed due to early islet loss and immune rejection. Reactive oxygen species (ROS) have been demonstrated to be involved in graft damage...
Diabetic cardiomyopathy (DCM) is a common complication leading to accelerated cardiovascular failure in diabetic patients. Even though the exact mechanism(s) behind this disease still remain unclear, research from several laboratories including our...
The leading cause of death in the United States is cardiovascular disease, a result of atherosclerosis. The reducing agent N-(2-Mercaptopropionyl)glycine (MPG) as been found to be an effective antioxidant therapy in a number of conditions, and our...
Autism Spectrum Disorder (ASD) is an idiopathic pervasive neurodevelopmental disorder associated with various neuropathologies and immunological dysfunctions. Cytokines are regulatory proteins that facilitate communication between the immune and...
