Arylamine N-acetyltransferases, NAT1 and NAT2, catalyze the detoxification and/or activation of drugs and aromatic amine carcinogens. Single nucleotide polymorphisms or SNPs result in different human NAT2 genotypes thus dividing the population into rapid, intermediate, and slow acetylators. We hypothesize allelic variants of NAT2 genotype will decrease levels of N-acetylation, cytotoxicity, oxidative stress, DNA adduct formation, and mutagenesis compared to the reference allele NAT2*4. Cryopreserved human hepatocytes expressing different NAT2 genotypes and NER-deficient Chinese hamster ovary (CHO) cells transfected with human CYP1A2 and human NAT2*4, NAT2*5B or NAT2*7B have been used to investigate N-acetylation of different xenobiotics. In …
Tobacco-Derived Aldehydes: Platelet Activation, Thrombosis, And The Role Of Trpa1., Andre Dwayne Richardson
Tobacco-Derived Aldehydes: Platelet Activation, Thrombosis, And The Role Of Trpa1., Andre Dwayne Richardson
Electronic Theses and Dissertations
Cigarette smoking is the single largest risk factor for cardiovascular disease (CVD) pathophysiology. Numerous researchers have shown potential associations between aldehydes in tobacco-derived aerosols from mainstream cigarette smoke (MCS) or electronic cigarettes (e-cigs) and their cardiotoxicity by damaging blood vessel endothelium. The severity of exposure to these toxicants can furthermore lead to adverse cardiovascular outcomes such as myocardial infarctions, stroke, coronary and peripheral artery disease, or atherosclerosis due to blood clots, a pro-thrombotic event. However, the mechanisms by which levels of harmful and potentially harmful constituents (HPHCs) such as aldehydes induce thrombosis are not well-known. Of specific interest, evidence has …

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. …

Dual Role Of Antimicrobial Peptide Cathelicidin In Alcohol-Associated Liver Disease., Fengyuan Li

Patients with alcohol-associated liver disease (ALD) have high morbidity and mortality in its severe forms. One of the major features in different forms of ALD is the altered gut microbiota. Antimicrobial peptides (AMPs) play a crucial role in maintaining gut microbiota homeostasis. LL-37 (known as CRAMP in mouse) is the sole member of the human cathelicidin family and has piqued great research interest for its dual role in modulating microbiota and the immune response in metabolic diseases. Inflammasome activation is an important component of the liver pathophysiology in ALD and requires two signals for its full activation to induce the …
