Acrolein Is A Critical Mediator Of Alcohol-Induced Liver And Intestinal Injury In Alcoholic Liver Disease., Wei-Yang (Jeremy) Chen

Electronic Theses and Dissertations

Alcohol consumption can cause alcoholic liver disease (ALD), which remains a major cause of morbidity and mortality in the United States. Chronic alcohol consumption causes a pro-oxidant environment in the liver and increases hepatic lipid peroxidation. Acrolein is the most reactive and toxic aldehyde generated through lipid peroxidation. Acrolein forms protein adducts and triggers endoplasmic reticulum (ER) stress and hepatocyte apoptosis, which are recognized etiologic factors in ALD. Several studies have established the critical role of the gut-liver axis in ALD pathogenesis, wherein alcohol-induced gut barrier dysfunction contributes to liver injury. This study investigates, in vitro and in vivo, the …

The Role Of Src Kinase Activation In Lung Epithelial Alterations In Response To The A,B-Unsaturated Aldehyde Acrolein, Robert Bauer

Graduate College Dissertations and Theses

Cigarette smoke (CS) exposure is the leading cause of preventable death in the United States contributing to over 480,000 deaths a year with over 300 billion dollars in CS related costs spent per year. While the dangers of CS exposure have been studied and characterized for decades being largely attributed to reactive oxygen species and oxidative stress, increasing evidence suggests that reactive aldehydes in CS, specifically the α,β-unsaturated aldehyde acrolein, are responsible for many of the negative pathologies associated CS exposure. Previous work has shown that acrolein can bind directly to a number of cellular proteins containing redox sensitive cysteine …
