Role Of Heme Oxygenase-1 In Acute Kidney Injury, Subhashini Bolisetty
Role Of Heme Oxygenase-1 In Acute Kidney Injury, Subhashini Bolisetty
All ETDs from UAB
Acute kidney injury (AKI), defined as the rapid loss of kidney function, is often seen in the setting of multiple organ failure in critically ill patients. Lack of established therapeutic approaches to overcome AKI has lead to unacceptably high incidence of morbidity and mortality in these patients. The molecular mechanisms that lead to AKI often have oxidative stress as a common pathogenic event. The kidney responds by prompt induction of its own anti-oxidant machinery including the highly inducible, anti-inflammatory and anti-apoptotic gene-heme oxygenase-1 (HO-1). This microsomal enzyme degrades pro-oxidant heme, which is released from heme proteins. The cytoprotective properties of …

Exposure to air pollutants are known to induce airway inflammation, decrease lung function, and worsen existing pulmonary conditions such as asthma. Additionally, air pollutant exposure has also been shown to impact cardiovascular health. Although these pollutant-induced cardiovascular effects were considered to be mediated by the direct action of pollutants upon the cardiovascular tissue and/or the indirect release of pro-inflammatory factors into the circulation, the relative contribution of the two pathways remained equivocal. Recently, several epidemiology studies associated ozone exposure with cardiovascular mortalities. However, relatively few studies to date have examined ozone in this context. In order to address our hypothesis …
Chronic Alcohol Consumption Promotes Opening Of The Mitochondrial Permeability Transition Pore And Increases Mitochondrial Injury In Liver, Adrienne Lester King
Chronic Alcohol Consumption Promotes Opening Of The Mitochondrial Permeability Transition Pore And Increases Mitochondrial Injury In Liver, Adrienne Lester King
All ETDs from UAB
Alcoholic liver disease is a serious public health concern. In particular, the mitochondrion is a specific target of ethanol toxicity and much of the damage can be related to unregulated Ca2+ homeostasis and oxidative stress which are key players in the induction of the mitochondrial permeability transition pore (MPTP) within the organelle. The mechanism behind the induction of the MPTP remains elusive. Therefore, this body of work will provide insight on what effects chronic alcohol consumption has on mitochondrial dysfunction with an emphasis on the MPTP. Chapter 2: Assessment of mitochondrial dysfunction arising from treatment with hepatotoxicants provides a description …
