The Cardiovascular Effects Of Tobacco Product-Derived Aldehydes: Contribution Of Transient Receptor Potential Ankyrin-1., Lexiao Jin May 2020

The Cardiovascular Effects Of Tobacco Product-Derived Aldehydes: Contribution Of Transient Receptor Potential Ankyrin-1., Lexiao Jin

Electronic Theses and Dissertations

Cardiovascular diseases (CVD) are the leading cause of death in most countries and are significant health and financial burden worldwide. Smoking contributes to more than 480,000 premature deaths annually -- accounting for one of every five deaths in the United States each year. Numerous studies have shown that smoking increases the risk of factors including endothelial dysfunction, thrombosis, and atherosclerosis, which may lead to an incidence of myocardial infarction, coronary artery disease, and stroke. Electronic cigarettes (e-cigarettes) are a new kind of tobacco product, and some studies show that e-cigarettes also could induce CVD since both e-cigarettes and conventional tobacco …


Tobacco Product-Derived Aldehydes: Effects On Circulating Angiogenic Cells & Implications For Cardiovascular Disease., Jordan B. Lynch May 2020

Tobacco Product-Derived Aldehydes: Effects On Circulating Angiogenic Cells & Implications For Cardiovascular Disease., Jordan B. Lynch

Electronic Theses and Dissertations

Cardiovascular disease (CVD) is the leading cause of death worldwide. Tobacco smoke is the most significant modifiable risk factor in CVD development and contains numerous toxic compounds, including aldehydes, which have been linked to CVD. Formaldehyde, acetaldehyde, acrolein, and crotonaldehyde have been identified as significant contributors to cigarette-induced health effects, but the mechanism of these effects is not well understood. These aldehydes are also found in aerosols produced by e-cigarettes (e-cigs). The goal of this dissertation was to explore the systemic, hematological, and endothelium-related effects of exposure to tobacco products and constituent aldehydes and to identify potential mechanisms of injury. …


Lipid Aldehydes Are Substrates And Transcriptional Regulators Of Cytochromes P450., Immaculate Amunom May 2008

Lipid Aldehydes Are Substrates And Transcriptional Regulators Of Cytochromes P450., Immaculate Amunom

Electronic Theses and Dissertations

4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are highly reactive á,â-unsaturated aldehydes. 4-HNE and acrolein are generated in vivo as products of lipid peroxidation. These aldehydes are implicated in the onset of several diseases including atherosclerosis and neurodegenerative disease. They also react with nucleophilic cellular macromolecules including proteins, DNA and phospholipids. Some of these reactions in vivo lead to inhibition of enzyme activities, depletion of glutathione and oxidative stress. Because of their pathophysiological relevance, attention has focused during the last decade on the ability of mammals to metabolize these lipid aldehydes. The purpose of this study was therefore to determine the role …
