Changes In Environmental Conditions Affect The Two Isoforms Of Snap-25 Differently, Joseph Jackson, Dixon J. Woodbury, Tanner M. Blocker, Samuel W. Shumway, Jarom S. Sumsion, Thomas Weed, Jason Carlson, Nathan Mumford, Ryan Poland

Library/Life Sciences Undergraduate Poster Competition 2024

In the brain, neurons communicate via releasing and detecting neurotransmitters. Release occurs through exocytosis, following fusion of synaptic vesicles to neuronal cell membranes. This process is driven by formation of a dynamic quaternary protein structure known as the SNARE complex. SNAP-25 contributes two alpha helical domains to this complex. Neurons express SNAP-25 in two distinct isoforms, SNAP-25A (25A) and SNAP-25B (25B). These two isoforms vary by only 9 amino acids and are expressed differently depending on brain region and the developmental stage of the neuron [1]. The primary structures of 25A and 25B and their effect on SNARE complex formation …

Effects Of Post-Translational Histone Modifications On Transcription Rate, Jacob Hunter, Steven Johnson, Aaron Bohn, Sarah Ricks, Sarah Hodson, David Bates, Steven M. Johnson

Library/Life Sciences Undergraduate Poster Competition 2024

DNA structure and organization in eukaryotic cells significantly impacts the regulation of geneexpression, cellular properties and overall behavior. At the most fundamental unit of this organization,~147 bp of DNA wraps 1.7 times around a histone octamer core, forming a collective unit called thenucleosome. Positioning and occupancy of nucleosomes around promoter elements of genes is knownto be a strong regulator of transcription in eukaryotic nuclei. Post-translational modifications (PTM’s) tothe protruding N-terminal tails of histone proteins are known to influence chromatin structure and thusgene expression; however, relatively little is known about the residual effect of histone PTM’s ontranscription rate.

Air quality has important climate and health effects. There is a need, therefore, to monitor air quality both indoors and outdoors. Methods of measuring air quality should be cost-effective if they are to be used widely, and one such method is low-cost sensors (LCS). This study reports on the use of LCSs in Ulaanbataar, Mongolia to measure PM2.5 concentrations inside yurts or “gers”. Some of these gers were part of a non-government agency (NGO) initiative to improve insulating properties of these housing structures. The goal of the NGO was to decrease particulate emissions inside the gers; a secondary result …

From The Headlines: A Textual Analysis Of Social Polarization And Discord In Times Of Pandemic Across A Century In The United States, Alexa Demarco

Undergraduate Honors Theses

Within the past century, three major pandemics have affected the United States – the Spanish Flu, AIDS, and COVID-19. Each of these pandemics has tested the capabilities of the public health sector and the social resilience of the population. Scientists have studied the viruses and implemented public health measures to limit viral transmission, but the social responses to these preventative measures proved to be difficult to predict and control. The dissonance and polarization between the public health initiatives and the response of the general public in the most recent pandemic was apparent. Was this a pattern in other pandemics? Was …


Qualitative Proteomic And Genomic Analysis Of Klebsiella Pneumoniae Bacteriophage Kaomega, Emilee Carr Aug 2022

Qualitative Proteomic And Genomic Analysis Of Klebsiella Pneumoniae Bacteriophage Kaomega, Emilee Carr

Undergraduate Honors Theses

Klebsiella pneumoniae is a Gram-negative Enterobacteriaceae that is a common nosocomial pathogen causing pneumonia, infections in the bloodstream, wound infections, and meningitis. It has developed natural resistance to multiple antibiotics, most notably carbapenems which are often seen as the last line of defense against multi-drug resistant pathogens. Bacteriophages are being investigated as a promising alternative treatment to antibiotics in fighting these resistant pathogens. KaOmega, a Klebsiella pneumoniae bacteriophage, was isolated, sequenced, and annotated to characterize and understand its potential for use in a phage therapy. Characterization included Phyre2 analysis to predict putative protein functions based on structural homology, burst size …

Exploring Melatonin As A Treatment For Oral Ulcers, William H. Sutherland Jun 2022

Exploring Melatonin As A Treatment For Oral Ulcers, William H. Sutherland

Undergraduate Honors Theses

The hormone melatonin is best known for its role in the sleep-wake cycle, but its anti-inflammatory and antioxidant effects have significant implications that have not been fully explored in oral health. Some studies use melatonin to treat gastrointestinal ulcers, including duodenal ulcers and oral mucositis, but we found no study reporting its effects on more common oral ulcers, like aphthous stomatitis. We hypothesize that the anti-inflammatory and antioxidant characteristics of melatonin could effectively prevent and heal oral ulcers. In this paper, we review the literature on melatonin to propose its use as a treatment for oral ulcers. We also include …


The Regulation Of Atg9a-Mediated Aggrephagy By An Ulk1-Independent Atg13-Atg101 Complex, Joshua Youngs Jun 2022

The Regulation Of Atg9a-Mediated Aggrephagy By An Ulk1-Independent Atg13-Atg101 Complex, Joshua Youngs

Undergraduate Honors Theses

Aggrephagy, a type of autophagy, is an essential cellular process by which protein aggregates are collected and broken down in the lysosome. Protein aggregates are implicated in several diseases including Alzheimer’s disease, diabetes, and cancer. Here, we investigate the ATG13-ATG101 protein complex, a sub-complex of the canonical ULK1 complex whose regulatory role in aggrephagy is not completely understood. We also develop a protein fragment complementation (PFC) assay using the biotin ligase TurboID to study the functions of the ATG13-ATG101 complex with increased specificity. We demonstrate that ATG13 is required for optimal degradation of p62-ubiquitin condensates. We also show that a …

Potential Regulation Of Breast Cancer Invasion By Thymidine Kinase 1, Eliza E. Bitter, Rachel M. Morris, Toni O. Mortimer, Kai Barlow, Abigail Schekall, Michelle H. Townsend, Jonathan Skidmore, Brett E. Pickett, Kim L. O'Neill

Library/Life Sciences Undergraduate Poster Competition 2022

Breast cancer is the most common cancer in women and is largely treatable within the early stages of the disease. However, patient mortality drastically declines as the tumor begins to invade other tissues and metastasize, making aggressive phenotypes especially problematic to treat. Such treatment typically requires an aggressive and decisive multidisciplinary approach. The recent expansion of immunotherapy as a viable treatment option has greatly improved treatment outcomes, especially with aggressive breast cancer phenotypes. Thymidine kinase 1 (TK1) is a DNA salvage pathway enzyme that is highly expressed during S phase and involved in cell cycle repair. Past studies indicated that …

The Role Of Cd5 In Cd4+ T Cell Metabolism, Joshua Bennett, Kiara Whitley, Claudia Freitas Phd, Christopher Haynie, Carlos Moreno, Scott Weber

Library/Life Sciences Undergraduate Poster Competition 2022

T cells serve a key role in the immunological response in the adaptive system. Different receptors present on the T cell have certain roles and are able to either inhibit or stimulate signaling which consequently regulates the function and metabolism of the cell. CD5 is an inhibitory co receptor expressed on the surface of T cells known to regulate thymocyte selection and TCR signaling . Our goal is to better understand the effects of CD5 regulation in metabolism. Using metabolic flux assays, we found that CD5KO naïve T cells have increased glycolysis and mitochondrial respiration in comparison to wild type …


Encirclement Of Moving Targets Using Noisy Range And Bearing Measurements, Cammy Peterson, Puneet Jain, Randal Beard Aug 2021

Encirclement Of Moving Targets Using Noisy Range And Bearing Measurements, Cammy Peterson, Puneet Jain, Randal Beard

Faculty Publications

This paper presents theoretically justified controllers that use relative range and bearing measurements to steer a team of autonomous vehicles, operating without inertial position information, to circular trajectories around a constant-acceleration, constant-velocity, or stationary target. An extended Kalman filter is used to improve the noisy relative measurements and estimate the velocity of the moving target. These estimated values are used in the control laws to encircle constant-velocity moving targets. Lyapunov techniques are utilized to show that the vehicle will converge to the desired circular formations. Additionally, cooperating vehicles are shown to converge to a circular formation with equal temporal spacing …

On The Relationship Of Diabetes And Sleep Apnea: Evolution And Epigenetics, Nancy Wilson Aug 2021

On The Relationship Of Diabetes And Sleep Apnea: Evolution And Epigenetics, Nancy Wilson

Undergraduate Honors Theses

This thesis gives an overview of the relationship between diabetes, sleep apnea, obesity, and heart disease. It then addresses evidence that the traditional understanding of this relationship is incomplete or misleading. In the process, there is a brief discussion of the evolutionary rationale for the development and retention of sleep apnea in light of blood sugar dysregulation, as an adaptive mechanism in response to environmental stressors, followed by a brief overview of the general concepts of epigenetics. Finally, this paper presents the results of a literature search on the epigenetic marks and changes in gene expression found in sleep apnea …

A Fret Flow Cytometry-Based Screening Assay For Multiplex Analysis Of Metabolites In T. Brucei, Ronald A. Zegarra Jun 2021

A Fret Flow Cytometry-Based Screening Assay For Multiplex Analysis Of Metabolites In T. Brucei, Ronald A. Zegarra

Undergraduate Honors Theses

Kinetoplastid parasites are a significant public health issue in some tropical and subtropical regions of the world. Kinetoplastid parasites all require glycolysis for survival, with host glucose key for ATP production. One such parasite, Trypanosoma brucei, exclusively metabolizes glucose in its bloodstream form. Trypanosomal glycolysis is unique because it displays unconventional structural features. Hence, glucose metabolism has been studied extensively in T. brucei and is a therapeutic target in kinetoplastid parasites.The lack of in vivo analytical techniques for measuring vital glycolytic metabolites in situ has restricted the ability of researchers to test, with high sensitivity and specificity, the essential roles …


Exploration Of Fluorinated Α,Β-Dehydroamino Acids And Their Structure, Austin Lesueur Jun 2021

Exploration Of Fluorinated Α,Β-Dehydroamino Acids And Their Structure, Austin Lesueur

Undergraduate Honors Theses

This thesis explores the synthesis of fluorinated α,β-dehydroamino acids, specifically a fluorinated dehydrovaline derivative. Previous work has been done on the equivalent dehydrovaline derivative without fluorine present and this work builds toward the fluorinated version with the goal of comparing the two structurally. The synthesis presented here pulls from previous synthetic strategies employed for dehydrovaline while also exploring the synthetic impact of the electronegative fluorine atoms.
