Early-Onset Colorectal Cancer In Mice, Qi Zhang

Theses and Dissertations

Early-onset colorectal cancer (EOCRC) is the second most common cancer and the third leading cause of cancer mortality in people under 50 years old in the United States. Our hypothesis is that a high-fat diet (HFD), Allura Red AC, and/or psychological stress causes distal and rectal colon inflammation, which are associated with dysbiosis. Furthermore, chronic exposure to one or more of these elements increases the risk of EOCRC. A/J inbred mice were utilized in this study. The results are consistent with our hypothesis.

Overall findings are the following: (1) An HFD increased inflammatory scores and polyps’ burden in the distal …

Function Of Gpr68 In Normal Hematopoiesis And Malignant Hematopoietic Diseases, Xiaofei He

Theses and Dissertations

G protein-coupled receptor 68 (GPR68), as a proton-sensing receptor, is involved in numerous physiological processes. However, its specific functions in normal hematopoiesis and malignant hematopoietic diseases were unknown. Using a genetic loss of function approach (i.e. whole-body Gpr68^-/- mouse model), B lymphocytes were reduced under stressed conditions, such as aging and hematopoietic regeneration. However, hematopoietic stem cells (HSC) from Gpr68^-/- mice exhibited comparable function as HSC from wild type mice either under steady-state or upon stress. To determine whether the unaltered HSC function of Gpr68^-/- mice was due to compensatory effects of Gpr68 in nonhematopoietic cells, a …

Influenza Vaccination Coverage In Pediatric Patients With Inflammatory Bowel Disease, Kelly Brown

Senior Theses

Background: Children with chronic health conditions, including inflammatory bowel disease (IBD), are at especially high risk for influenza infection and complications. The Crohn’s & Colitis Foundation and American College of Gastroenterology recommend that IBD patients should receive annual influenza vaccination. The aims of this study were to evaluate influenza vaccination coverage over time and identify predictors of flu vaccination in pediatric IBD and non-IBD patients.

Methods: We utilized longitudinal data (2000 to 2016) from South Carolina Medicaid to conduct a matched cohort study. The primary exposure of interest was IBD diagnosis based upon ICD-9/10 diagnosis codes. Children with IBD were …

Plk1 Pbd Selective Inhibition As A Potential Cancer Therapy, Lauren E. Wilder

Senior Theses

Polo-Like Kinase 1 (PLK1) is a protein that has been found to be overexpressed in a variety of cancers including prostate and colorectal cancers, and it is often an indicator of poor patient prognosis. It has functions in initiating, maintaining, and completing mitosis, so it has an important role in controlling the proliferation of cells. PLK1 contains a highly conserved catalytic kinase domain and a less-conserved Polo Box Domain (PBD). Inhibiting the phospho-ligand binding of the PBD is a potential cancer therapy because it would prevent the cell from properly completing the cell cycle, thus inducing apoptosis. In Dr. McInnes’ …

Treatment With Protease Inhibitor And Development Of Diabetes Among Medicare Beneficiaries With Human Immune Virus/Acquired Immune Deficiency Syndrome (Hiv/Aids), Eric Ejike Chinaeke

Theses and Dissertations

Background: The possibility of an association between the use of protease inhibitors (PI) by HIV/AIDS patients and the occurrence of T2DM mellitus (T2DM) is largely debated. Medicare recipients are disproportionally affected by T2DM. Unfortunately, evidence is unavailable from that particular segment of the population. Clinical management of HIV/AIDS is progressively expanding to include chronic/metabolic complications, which may pose a significant economic burden to both the patients and the Medicare system, which are disproportionally impacted. Objectives: The aims of this project were to (1) examine the association between the use of PIs and the odds of developing T2DM among Medicare beneficiaries …
