Epidermal Growth Factor Receptor (Egfr) Inhibition By Polychlorinated Biphenyls Contributes To Non-Alcoholic Fatty Liver Disease (Nafld)., Josiah Hardesty Dec 2018

Epidermal Growth Factor Receptor (Egfr) Inhibition By Polychlorinated Biphenyls Contributes To Non-Alcoholic Fatty Liver Disease (Nafld)., Josiah Hardesty

Electronic Theses and Dissertations

This dissertation describes how poly-chlorinated biphenyls (PCBs) exacerbate the pathogenesis of non-alcoholic fatty liver disease (NAFLD). While PCBs were banned in 1979, they still persist in contaminated biota, including food, and are detected in human plasma and adipose. The body burden of PCBs is associated with elevation of liver enzymes and necrosis markers in humans, characteristic of NAFLD. PCB exposure in high-fat diet fed mice leads to steatohepatitis that recapitulate the findings seen in exposed humans. The global estimate of people diagnosed with NAFLD is up to 1 in 4 people, unrelated to dietary or genetic factors. The hepatic mechanisms …


The Role Of Nicotine, A7 Nicotinic Acetylcholine Receptors And Extracellular Matrix Remodeling In Pulmonary Fibrosis., Glenn Ward Vicary Dec 2016

The Role Of Nicotine, A7 Nicotinic Acetylcholine Receptors And Extracellular Matrix Remodeling In Pulmonary Fibrosis., Glenn Ward Vicary

Electronic Theses and Dissertations

The median survival for idiopathic pulmonary fibrosis (IPF) patients from diagnosis is a dismal 3 years. This condition is characterized by pulmonary fibroproliferation and excess production and disordered deposition of extracellular matrix (ECM) proteins resulting in obliteration of the original tissue architecture, loss of lung function and eventual death due to respiratory failure. The main hindrance to the development of effective treatments against pulmonary fibrosis is the late detection of its progression and is often of unknown cause. Tobacco smoke represents the most important environmental factor linked to the development of pulmonary fibrosis, with over 60% of IPF patients current …


The Effect Of Caffeine And Ethanol On Flatworm Regeneration., Erica Leighanne Collins Aug 2007

The Effect Of Caffeine And Ethanol On Flatworm Regeneration., Erica Leighanne Collins

Electronic Theses and Dissertations

Flatworms, or planarian, have a high potential for regeneration and have been used as a model to investigate regeneration and stem cell biology for over a century. Chemicals, temperature, and seasonal factors can influence planarian regeneration. Caffeine and ethanol are two widely used drugs and their effect on flatworm regeneration was evaluated in this experiment. Non-toxic levels of caffeine, a stimulant, and ethanol, a depressant, were determined. The tails of the flatworms were removed and the regeneration stage was analyzed every 3 days for 15 days to see the effect of these drugs alone and in combination on regeneration. For …


Studies On A 50s Ribosomal Precursor Particle As A Substrate For Erm E Methyltransferase Enzyme In Staphylococcus Aureus ., Indira Pokkunuri May 2007

Studies On A 50s Ribosomal Precursor Particle As A Substrate For Erm E Methyltransferase Enzyme In Staphylococcus Aureus ., Indira Pokkunuri

Electronic Theses and Dissertations

Erythromycin is a macrolide antibiotic that inhibits not only mRNA translation but also 50S ribosomal subunit assembly in bacterial cells. An important mechanism of erythromycin resistance is the methylation of 23S rRNA by erm methyl transferase enzymes. We are interested in investigating the true substrate for methylation because it is known from our work and the work of others that fully assembled 50S subunits are not substrates for methylation. We have published a model for 50S ribosomal subunit formation where, the precursor particle that accumulates in erythromycin treated cells is a target for methyl transferase activity. Current studies are aimed …
