Isolation Of Egfr-Containing Early Endosomes., Julie A. Gosney Aug 2016

Isolation Of Egfr-Containing Early Endosomes., Julie A. Gosney

Electronic Theses and Dissertations

The epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase (RTK) that is an integral component of proliferative signaling. When activated by a ligand at the plasma membrane, EGFR undergoes clathrin-mediated endocytosis. This spatial regulation of the receptor is an important regulator of receptor expression as it mediates its degradation. Endocytosis also has implications on EGFR downstream signaling, though the details are not fully understood. The goal of this thesis is to develop a method to isolate early endosomes in order to study downstream effectors associated with activated EGFR in this compartment. HeLa cells were used to test various …


A Plant-Made Cholera Toxin B Subunit Enhances Mucosal Wound Healing And Protects Against Ulcerative Colitis And Colon Cancer., Keegan J Baldauf Dec 2015

A Plant-Made Cholera Toxin B Subunit Enhances Mucosal Wound Healing And Protects Against Ulcerative Colitis And Colon Cancer., Keegan J Baldauf

Electronic Theses and Dissertations

This dissertation describes the previously unidentified effects of a plant-produced recombinant cholera toxin B subunit (CTBp) on the gastrointestinal (GI) tract and its ability to protect against inflammation in a mouse model of colonic injury and ulcerative colitis (UC). To comprehensively analyze CTBp’s impacts on the GI tract, we employed global analysis methodologies based on multi-color flow cytometry to analyze immune cell populations in GI and systemic lymphatic compartments, gene expression microarray to decipher transcript-level changes in the colon and small intestine, and 16S rRNA sequencing to characterize fecal microbiota. Based on a drastic shift observed in the immune cell …


Mechanisms And Intervention Strategies For Alcohol And Hiv-Antiretroviral Therapy-Induced Liver Injury., Hridgandh Donde Dec 2015

Mechanisms And Intervention Strategies For Alcohol And Hiv-Antiretroviral Therapy-Induced Liver Injury., Hridgandh Donde

Electronic Theses and Dissertations

Chronic alcohol consumption is a leading cause of liver disease and liver-related death worldwide. Alcoholic liver disease includes, hepatic steatosis, steatohepatitis and ultimately fibrosis and cirrhosis. Emerging evidence has established the important role of the “gut-liver” axis in the development of alcoholic liver disease (ALD). Our recent work indicated that chronic alcohol induced perturbations in the gut microbiome and consequent changes in fatty acids have a major impact on the development of intestinal barrier dysfunction and ALD. The aim of this study was to investigate whether treatment with tributyrin - a butyrate prodrug results in protection against ALD in terms …
