Search For Palladin, An Actin-Associated Protein, In Pig Retinal Pigmented Epithelium And Its Role In Epithelial-Mesenchymal Transition, Katrina Powell
Search For Palladin, An Actin-Associated Protein, In Pig Retinal Pigmented Epithelium And Its Role In Epithelial-Mesenchymal Transition, Katrina Powell
Undergraduate Theses
This study investigates the expression of Palladin, a phosphoprotein product of the PALLD gene, in the retinal pigmented epithelium (RPE). Palladin is an actin cross-linking protein and plays a role in cell adhesion and motility. Published reports have demonstrated that a down regulation of Palladin in colon cancer cells results in a reorganization of the actin cytoskeleton, causing the cells to lose their typical shape, become proliferative and migratory. This process is otherwise known as epithelial-mesenchymal transition (EMT). A similar EMT phenomenon is observed when the RPE is exposed to the vitreous humor in patients with proliferative vitreoretinopathy (PVR). In …
Changes In Fecal Glucocorticoid Levels And Possible Microbiome Profile Changes During Positive Enrichment In A Captive Population Of Tigers (Panthera Tigris), Sylvia R. Ramsey
Changes In Fecal Glucocorticoid Levels And Possible Microbiome Profile Changes During Positive Enrichment In A Captive Population Of Tigers (Panthera Tigris), Sylvia R. Ramsey

Cortisol is a hormone that is released in response to stress. Cortisol can be damaging in high amounts and it is ideal to maintain at a low level. Captive animals can experience high baseline levels of cortisol during their captivity, verses their non-captive counterparts, (Terio, Marker, & Munson, 2004). Enrichment, a stimulus that encourages an animal to perform natural behavior, is offered to captive animals to allow the animal to exhibit natural behaviors and hopefully lower stress levels. This experiment analyzes if exposure to a positive enrichment significantly impacts an animal’s fecal cortisol levels. Fecal cortisol levels are indicative of …
Investigations Into The Cellular Target Of 4-Trifluoromethoxy Chalcone Via Darts Method, Jordan Stacy
Investigations Into The Cellular Target Of 4-Trifluoromethoxy Chalcone Via Darts Method, Jordan Stacy
Undergraduate Theses
Cellular drug target discovery is an important step in any drugs journey from bench to bedside. This is true for our lab's molecule of interest, the Chalcone. The Chalcone molecule and its derivatives have been identified as small, plant-derived secondary metabolites that, when interacting with human cancer cell lines, trigger apoptotic pathways leading to varying levels of cell death. One derivative, 4-Trifluoromethoxy Chalcone (4TFM), was identified through screenings as inducing the highest death rate in A549 cancer cells, in conjunction with having the lowest IC50, making it a good candidate to use in searching for the currently unknown cellular target …

Antibacterial And Antioxidant Potential Of A Novel Plant, Eriodictyon Californicum, And Its Healing Abilities, Allie Richards
Undergraduate Theses
Our body is under constant attack of oxidative stress (OS). OS is a crucial factor in the pathogenesis and progression of various chronic diseases such as diabetics, rheumatoid arthritis, myocardial infarction, cardiovascular diseases, stroke, cancer, Alzheimer’s disease, Parkinson’s disease, aging and more. The main cause of OS is free radicals, which are continuously generated in our body during normal metabolic processes. These free radicals have the potential to damage any of our key biomolecules. To protect ourselves from the toxic effect of free radicals the human body has a built-in army of antioxidants that play an important role in the …
The Effect Of Cadmium On Ovarian Adenocarcinoma Cell Lines: An Investigation Of The Possible Mechanism Of Action, Haley Todd
Undergraduate Theses
Cadmium, a heavy metal and carcinogen, is an environmental and workplace contaminate. As a known endocrine disruptor, it can mimic the proliferative effects of estrogen and is classified as a metalloestrogen. While the proliferative effect of estrogen on cancerous cell growth has been well established, the effects of cadmium have not been fully examined. To determine if cadmium stimulates growth in two human ovarian adenocarcinoma cell lines, OVCAR3 and SKOV3, cells were treated for 48 hours with varying concentrations of cadmium, 0.001 µM – 10 µM, and growth was measured using a cell proliferation assay. Both cell lines showed a …
