The Identification Of Long Non-Coding Rna Zfas1 Through An Exploratory Rna-Sequencing Analysis And Its Association With Epithelial-To-Mesenchymal Transition In Colon Cancer Adenocarcinoma., Stephen J. O'Brien
Electronic Theses and Dissertations
Colorectal adenocarcinoma is the fourth most common cancer diagnosed worldwide and is a significant cause of morbidity and mortality. This dissertation performed an exploratory RNA-sequencing analysis comparing gene expression between colon adenocarcinoma tissue and paired normal colon epithelium. After identification of a number of lncRNAs that were increased in expression in colon adenocarcinoma compared to normal colon epithelium, we aimed to validate the expression and investigate their function in vitro. Specifically, we focused on the lncRNA ZFAS1 and its association with epithelial-to-mesenchymal transition. These studies found the following: 1. Seven candidate lncRNAs were identified from the exploratory RNA-sequencing analysis to …
The Effects Of Nicotine And Cigarette Smoking On Cardiac Electrophysiology., Affan B. Irfan
The Effects Of Nicotine And Cigarette Smoking On Cardiac Electrophysiology., Affan B. Irfan
Electronic Theses and Dissertations
Cigarette smoking is a leading cause of preventable disease and premature death worldwide. The adverse effects of cigarette smoking, including proarrhythmia, are related to the mixture of chemicals, including nicotine (which sustains tobacco addiction). However, it remains unclear which individual tobacco smoke constituents and biological pathways mediate this increased risk. The purpose of this research was to explore the chronic effects of cigarette smoking, as well as compare the acute effects of nicotine and cigarette smoking, and the possible role of β-adrenoreceptors, on human cardiac electrophysiology. Chapter 1 is a comprehensive literature review of (a) the ex vivo and in …
Characterizing The Role Of Extracellular Matrix In Non-Small Cell Lung Carcinoma Metastasis Using A 3d Microenvironment Mimetic In-Vitro Culture System., Douglas John Owulaku Saforo
Characterizing The Role Of Extracellular Matrix In Non-Small Cell Lung Carcinoma Metastasis Using A 3d Microenvironment Mimetic In-Vitro Culture System., Douglas John Owulaku Saforo
Electronic Theses and Dissertations
Lung cancer is the leading cause of cancer related death in the United States and worldwide. Five-year survival rates for non-small cell lung carcinoma patients have not improved in decades, and a majority of patients succumb to metastasis. Identification of therapeutic targets for metastatic disease is essential for the development of novel therapies. However, current 2-dimensional (2D) in vitro models are not reflective of the tumor microenvironment (TME) and are inadequate in identifying therapeutic targets. We adapted a 3-dimensional (3D) extracellular matrix (ECM) in vitro model to a hypoxic incubator to approximate physiological hypoxia of the TME in a microenvironment …
Comparative Spending Of Medicaid Dollars On Child Participants Of Kentucky’S Sobriety Treatment And Recovery Teams Program Versus A Matched Comparison Group., Matthew Thomas Walton
Comparative Spending Of Medicaid Dollars On Child Participants Of Kentucky’S Sobriety Treatment And Recovery Teams Program Versus A Matched Comparison Group., Matthew Thomas Walton
Electronic Theses and Dissertations
Child protective services agencies have long observed the complicating role that parental substance use and addiction plays in cases of child maltreatment. Families who struggle with these problems present unique challenges for child welfare professionals. These families are typically more difficult to engage, more likely to have children removed from the home, and have poorer outcomes when compared to other families. These poorer outcomes often include health problems. Addiction has well-known effects on health, and the specific manifestations of these problems for parents have been documented for years in child protection casework. However, what has been less investigated are the …
Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin
Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin
Electronic Theses and Dissertations
Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …
An Evaluation Of The Supply And Demand Of Radiation Oncology Medical Physicists In The United States., Christine Marie Swanson
An Evaluation Of The Supply And Demand Of Radiation Oncology Medical Physicists In The United States., Christine Marie Swanson
Electronic Theses and Dissertations
Background: This dissertation is a mixed methods evaluation of the radiation oncology medical physics workforce in the United States. Radiation oncology medical physicists serve a vital role in the safe treatment of patients with radiation therapy. While cancer incidence continues to rise, the pathways to board certification in radiation oncology medical physics continue to narrow causing a potential shortage of radiation oncology physicists in the United States. While there is no lack of data about the medical physics community it has scarcely been used to evaluate the current state of the workforce. In order to ensure patient safety, appropriate physics …
