Casting For A Putative Dna Binding Sequence For Nbmp2, Brian Earley, Dr. Laura Bridgewater
Journal of Undergraduate Research
Bmp2 is a secretory mammalian protein that plays important roles in bone development and adult pathology. Recently, a nuclear variant (nBmp2) was discovered with an unknown function for this typically secretory protein in the nucleus (Felin et al., 2010). The purpose of this project is to find an in vitro DNA binding sequence for nBmp2. This discovery would lead to further research for how nBmp2 could affect transcription in vivo. However, since the conception of this CASTing project 16 months ago, I have faced challenges in plasmid construction, cell culture, and concessions with a fused nBmp2:GFP plasmid. While the plasmid …

Genomic And Proteomic Analysis Of An Erwinia Amylovora Phage, Alicia Brighton, Dr. Julianne Grose
Journal of Undergraduate Research
Fireblight is a disease, caused by the bacteria Erwinia amylovora, that can infect some fruit trees, including apple and pear trees. When an infection occurs, the effects can be devastating—any infected part of the tree must be removed and destroyed, sometimes resulting in loss of the entire tree. Furthermore, in the warm and moist conditions typical of springtime, the spread of fireblight can be nearly impossible to control with current management methods.1

The Heat Shock Response, Heat Tolerance, And Drosophila Melanogaster Nora Virus, Blase Rokusek
Biology Theses, Dissertations, and Student Creative Activity
The heat shock response (HSR) is highly conserved across the animal kingdom and is characterized by the activation of heat shock factors (HSF) and the subsequent induction of inducible heat shock proteins (HSP). The HSR and associated HSPs have been implicated in a variety of disease states. In this project, we explored two aspects of this response. First., we expanded the scope of the Drosophila melanogaster heat tolerance phenotype by involving an automated measure of activity. We discovered that heat hardening reduces motility during subsequent heat stress, and we provide evidence that the level of relative early motility can predict …

Nebraska Center for Virology: Faculty Publications
Many chloroviruses replicate in Chlorella variabilis algal strains that are ex-endosymbionts isolated from the protozoan Paramecium bursaria, including the NC64A and Syngen 2-3 strains. We noticed that indigenous water samples produced a higher number of plaque-forming viruses on C. variabilis Syngen 2-3 lawns than on C. variabilis NC64A lawns. These observed differences led to the discovery of viruses that replicate exclusively in Syngen 2-3 cells, named Only Syngen (OSy) viruses. Here, we demonstrate that OSy viruses initiate infection in the restricted host NC64A by synthesizing some early virus gene products and that approximately 20% of the cells produce a …

Understanding Ubiquitin-Like Signaling At The Host-Pathogen Interface, Danna Eloisa Guzman Gonzalez
University Honors Theses
Research on pathogen intervention and ubiquitin modification has increased over the last few years but a lot is still unknown about ubiquitin-like modifiers (Ubl) and how or if they are modified by pathogens in the same way as Ubiquitin. In this work, two different studies conducted over the course of 2 years are highlighted. The first study focused on purifying and synthesizing four activity based probes in order to study enzymatic activity in the Ubl-modification systems. These probes were reacted with virulence factors isolated from different bacteria and it was concluded that there were unexpected bands formed between some of …

University Honors Theses
The purpose of this thesis is to explore the interplay between the environment, lifestyle, and composition of human microbiomes across different communities, with a specific focus on immune and digestive health. This literature review investigates three distinct types of communities: isolated/traditional, transitional, and urban/industrialized communities, each characterized by unique environments, societal structures, and interactions. These factors contribute to the distinct microbial populations and compositions within each community. It is impossible to avoid contact with microorganisms as they are present in every aspect of our lives, from the air we breathe, the water we drink, the soil we walk on, the …

Investigating The Mammillary Bodies As An Early Target Of Alzheimer's Disease, Cole Martinson
University Honors Theses
Alzheimer's disease (AD) is the most common form of dementia. With minimal treatment options and no cure, developing a deeper understanding of the pathology of the disease is crucial. For nearly four decades, the accumulation of beta-amyloid (Aβ) plaques has been correlated with the disease and its progression. Previous studies mapping this accumulation show that the mammillary bodies (MB) are an early target of the disease. Glutamatergic neurons are of key interest due to their prevalence in the central nervous system, specifically the MB. To understand the effects of AD on the glutamatergic system, we used vesicular glutamate transporter 2 …

The focus on using alternative natural products for cancer prevention and treatment has been increasing over the past decade. Among these natural products, Manuka honey (MH) has been extensively investigated for its antimicrobial, wound healing, and anticancer effects. The current study aimed to characterize the immunomodulatory capacity of MH using both in vitro and in vivo approaches and investigate its potential to modulate anti-tumor immune responses in a preclinical model of colorectal cancer. We demonstrate that MH can directly act on macrophages to induce gene expression of several inflammatory cytokines and chemokines and the production of TNF-a, a major proinflammatory …

Dissertations
Water scarcity is one of the major challenges facing humanity today, driven by population growth, economic development, and dietary shifts towards more water-intensive animal products. To address this issue, efficient water resource management and recycling of wastewater are essential. However, around 80% of wastewater globally is discharged into water bodies without treatment, posing a risk to ecosystems and human health. Pathogens, or harmful microorganisms, are a primary cause of water impairment and the transmission of waterborne diseases, leading to increased mortality rates. Traditional methods of treating pathogens involve the use of radiation or chemical disinfectants. Nonetheless, these methods have drawbacks, …

Ecology Of Viruses In Marine And Coastal Oxygen-Depleted Waters, Sophie Jurgensen
LSU Doctoral Dissertations
Deoxygenation of marine and coastal waters, both caused and exacerbated by a suite of abiotic and biotic factors, has been documented for more than sixty years. The incidence and severity of low-oxygen areas is predicted to expand globally in the coming decades. Despite their colloquial moniker “dead zones,” low-oxygen areas contain thriving and diverse microorganisms that have significant impacts on global biogeochemical cycles including contributing to positive feedback loops that further expand low-oxygen areas. While the diversity and activity of these microorganisms is beginning to be elucidated, the ecology of their viruses is particularly understudied. In this dissertation, I present …

Considerations For The Use Of Mycorrhizal Fungi Inoculants In Coal Mine Reclamation And Reforestation In Appalachia: A Guide Of Best Practices And Management Recommendations, Cole Hansen Reistrup
Master's Projects and Capstones
Nearly all terrestrial plants form symbiotic relationships with mycorrhizal fungi. These beneficial soil microbes support plant health by increasing plants’ access to nutrients and water, protecting them from pathogens, improving soil properties, and more. A challenge to restoring forests on coal mined land in Appalachia is that mine soils are often degraded in a number of ways, including lacking mycorrhizal fungi, which makes mine soils difficult for trees to grow upon. Substantial improvements to coal mine reforestation success have been made since the development of the Forestry Reclamation Approach in 2005 that provides guidelines for how to create a suitable …

The Influence Of Sampling Frequency On Bee Species Richness, Courtney Caccamo
Biology Student Scholarship
As one of Earth’s most valuable pollinators, bees provide important pollination services to wild plant species and crops alike (Winfree 2010). But, in recent years, bee populations appear to be declining due to a variety of anthropogenic drivers (Potts et al. 2010). Quantifying the extent of bee population decline is difficult because there is currently a lack of a standardized protocol for how best to survey bee populations (Tepedino & Portman 2021). One of the commonly used survey methods is pan trapping, which involves leaving out yellow, white, and blue bowls filled with soapy water to passively sample the species …

Overexpressing Two Helicobacter Pylori Small Rnas From A Bacterial Pathogenicity-Related Chromosomal Region To Investigate Their Regulation Of Virulence Genes, Roxanne N. Mcpeck, Olivia F. Morgan, Andrea R. Castillo Phd
2023 Symposium
The bacterial pathogen Helicobacter pylori infects the stomachs of approximately 50% of humanity, causing symptomatic disease (e.g., stomach ulcers, gastric cancer, and MALT lymphoma) in 10-15% of the infected. Colonizing the acidic, inhospitable stomach requires H. pylori to tightly regulate gene expression despite lacking many common bacterial genetic regulatory elements. The pathogen may compensate by using abundant non-protein-coding small RNAs (sRNAs) to regulate gene expression, including of infection-intensifying virulence genes. Additionally, severe disease and cancer correlate with infection by H. pylori strains that contain a nonessential chromosomal region, the cytotoxin-associated gene pathogenicity island (cagPAI). This encodes powerful virulence …

Influenza C virus (ICV) is increasingly associated with community-acquired pneumonia (CAP) in children and its disease severity is worse than the influenza B virus, but similar to influenza A virus associated CAP. Despite the ubiquitous infection landscape of ICV in humans, little is known about its replication and pathobiology in animals. The goal of this study was to understand the replication kinetics, tissue tropism, and pathogenesis of human ICV (huICV) in comparison to the swine influenza D virus (swIDV) in guinea pigs. Intranasal inoculation of both viruses did not cause clinical signs, however, the infected animals shed virus in nasal …
