Establishing A Drosophila Colon Cancer Model To Study Interactions And Therapeutic Targets Of Oncogenic Pathways, Kathleen T. Mccaslin
Honors Theses
The objective of this project is to develop an in vivo colorectal cancer (CRC) model in Drosophila melanogaster to test the role of Ras and Wnt pathways in gastrointestinal cancer as potential therapeutic targets. To do so, we have (a) developed a CRC model in flies, (b) tested the levels of Ras and Wnt pathway activity in this model, and (c) will use drugs to find inhibitors of these pathways. Using fly mutants and transgenic flies we have created small patches of cancerous cells in the fly intestine in which have activated oncogenic Ras (mutation RasV12) and dominant negative p53 …

Mosses inhabit nearly all terrestrial ecosystems and engage in important interactions with nitrogen-fixing microbes, sperm-dispersing arthropods, and other plants. It is hypothesized that these interactions could be mediated by biogenic volatile organic compounds (BVOCs). Moss BVOCs may play fundamental roles in influencing local ecologies, such as biosphere–atmosphere–hydrosphere communications, physiological and evolutionary dynamics, plant–microbe interactions, and gametophyte stress physiology. Further progress in quantifying the composition, magnitude, and variability of moss BVOC emissions, and their response to environmental drivers and metabolic requirements, is limited by methodological and analytical challenges. We review several sampling techniques with various analytical approaches and describe best practices …

Before the Perseverance rover landing, the acoustic environment of Mars was unknown. Models predicted that: (1) atmospheric turbulence changes at centimetre scales or smaller at the point where molecular viscosity converts kinetic energy into heat1, (2) the speed of sound varies at the surface with frequency2,3 and (3) high-frequency waves are strongly attenuated with distance in CO2 (refs. 2,3,4). However, theoretical models were uncertain because of a lack of experimental data at low pressure and the difficulty to characterize turbulence or attenuation in a closed environment. Here, using Perseverance …
How Social Media’S Rhetoric Shapes The Social Identity Of Online Groups: Forming, Confirming And Reinforcing And The Algorithmic Role, Crystal Rose
Departmental Honors & Graduate Capstone Projects
The world has become integrated with technology at a rapid rate. The rhetoric of online platforms, due to technology integration, allows people to connect, converse, and meet others who have common character traits. Eyman (2015) defines rhetoric as an action that intends to persuade and form meaning. These platforms are referred to as "social media," which are online networks made by people who use rhetoric to form, confirm, and reinforce the connections of platform users with common character traits: Hobbies, thoughts, race, gender, or religion. These common character traits make up one's social identity. This study details the findings of …
The Impact Of Anaerobic Exposure And Propionate On The Kinetics And Pathogenesis Of Listeria Monocytogenes, Mackenzie T. Martin
The Impact Of Anaerobic Exposure And Propionate On The Kinetics And Pathogenesis Of Listeria Monocytogenes, Mackenzie T. Martin
Honors Theses
Listeria monocytogenes is a foodborne pathogen commonly found in ready-to-eat deli and dairy products. This foodborne pathogen is responsible for the disease listeriosis, which disproportionately impacts immunocompromised individuals. This research aims to evaluate how natural intestinal environments influence the pathogenesis of Listeria. One particular environmental condition that has a well-documented effect on Listeria is varying levels of oxygen. Specifically, anaerobic exposure during the growth of Listeria greatly impacts subsequent intracellular pathogenesis. When grown and adapted under anaerobic conditions, Listeria overall exhibits decreased intracellular survival and decreased cell to cell spread. However, the presence of propionate, a natural byproduct of fermentation …

Extreme weather events are predicted to increase as a result of climate change, yet amphibian responses to extreme disturbance events remain understudied, especially in the Neotropics. Recently, an unprecedented windstorm within a protected Costa Rican rainforest opened large light gaps in sites where we have studied behavioral responses of diurnal strawberry poison frogs (Oophaga pumilio) to ultraviolet radiation for nearly two decades. Previous studies demonstrate that O. pumilio selects and defends perches where ultraviolet radiation (UV-B) is relatively low, likely because of the lethal and sublethal effects of UV-B. In this natural experiment, we quantified disturbance to O. pumilio habitat, …
Neuroprotective Effect Of Liraglutide In An Experimental Mouse Model Of Multiple Sclerosis: Role Of Ampk/Sirt1 Signaling And Nlrp3 Inflammasome, Reham A. Ammar, Ahmed F. Mohamed, Mohamed M. Kamal, Marwa M. Safar, Noha F. Abdelkader

Pharmacy
The heterogeneous nature of multiple sclerosis (MS) and the unavailability of treatments addressing its intricate network and reversing the disease state is yet an area that needs to be elucidated. Liraglutide, a glucagon-like peptide-1 analogue, recently exhibited intriguing potential neuroprotective effects. The currents study investigated its potential effect against mouse model of MS and the possible underlying mechanisms. Demyelination was induced in C57Bl/6 mice by cuprizone (400 mg/kg/day p.o.) for 5 weeks. Animals received either liraglutide (25 nmol/kg/day i.p.) or dorsomorphin, an AMPK inhibitor, (2.5 mg/ Kg i.p.) 30 min before the liraglutide dose, for 4 weeks (starting from the …
Functional Facets Of Intergenic Hairpin Structures In Genus Caulobacter, Geetha Saarunya Clarke
Functional Facets Of Intergenic Hairpin Structures In Genus Caulobacter, Geetha Saarunya Clarke
Theses and Dissertations
DNA replication, recombination and repairs maintain bacterial genome stability. But these processes may also induce genome rearrangements leading to inter andintra chromosomal structural variations. Genus Caulobacter undergoes extensive genome rearrangements. Genomic studies in bacteria usually focus on the codingregions, but there is important information present in the intergenic DNA spaces inaddition to the regulatory elements involved in transcription. Recently, Ely published a new model for recombination in genus Caulobacter with simultaneousloss and gain of genes resulting from preferential recombination at non- homologous regions flanked by regions of homology. In my dissertation, I observedand catalogued hairpin structures at known sites of …

Winter Torpor Expression Varies In Four Bat Species With Differential Susceptibility To White-Nose Syndrome, Reilly T. Jackson, Emma V. Willcox, Riley F. Bernard
Winter Torpor Expression Varies In Four Bat Species With Differential Susceptibility To White-Nose Syndrome, Reilly T. Jackson, Emma V. Willcox, Riley F. Bernard
Biological Sciences Faculty Publications and Presentations
Studies examining the overwintering behaviors of North American hibernating bats are limited to a handful of species. We deployed temperature-sensitive transmitters on four species of bat that exhibit differences in their susceptibility to white nose syndrome (WNS; Myotis grisescens, M. leibii, M. sodalis, and Perimyotis subflavus) to determine if these differences are correlated with behavior exhibited during hibernation (i.e., torpor expression and arousal frequency). Mean torpor skin temperature (Tsk) and torpor bout duration varied significantly among species (P ≤ 0.024), but arousal Tsk and duration did not (P ≥ 0.057). One of the species with …
