A Parapoxviral Virion Protein Targets The Retinoblastoma Protein To Inhibit Nf-Κb Signaling, Ponnuraj Nagendraprabhu, Sushil Khatiwada, Sabal Chaulagain, Gustavo A. Delhon, Daniel L. Rock

School of Veterinary and Biomedical Sciences: Faculty Publications

Poxviruses have evolved multiple strategies to subvert signaling by Nuclear Factor κB (NF-κB), a crucial regulator of host innate immune responses. Here, we describe an orf virus (ORFV) virion-associated protein, ORFV119, which inhibits NF-κB signaling very early in infection (≤30 min post infection). ORFV119 NF-κB inhibitory activity was found unimpaired upon translation inhibition, suggesting that virion ORFV119 alone is responsible for early interference in signaling. A C-terminal LxCxE motif in ORFV119 enabled the protein to interact with the retinoblastoma protein (pRb) a multifunctional protein best known for its tumor suppressor activity. Notably, experiments using a recombinant virus containing an ORFV119 …

Structural Studies Demonstrating A Bacteriophage-Like Replication Cycle Of The Eukaryote-Infecting Paramecium Bursaria Chlorella Virus-1, Elad Milrot, Eyal Shimoni, Katya Rechav, Tamar Unger, James L. Van Etten, Abraham Minsky

James Van Etten Publications

A fundamental stage in viral infection is the internalization of viral genomes in host cells. Although extensively studied, the mechanisms and factors responsible for the genome internalization process remain poorly understood. Here we report our observations, derived from diverse imaging methods on genome internalization of the large dsDNA Paramecium bursaria chlorella virus-1 (PBCV-1). Our studies reveal that early infection stages of this eukaryotic- infecting virus occurs by a bacteriophage-like pathway, whereby PBCV-1 generates a hole in the host cell wall and ejects its dsDNA genome in a linear, base-pair-by-base-pair process, through a membrane tunnel generated by the fusion of the …

Differential Precipitation And Solubilisation Of Proteins, Barry J. Ryan, Gemma K. Kinsella

Books/Book Chapters/ Proceedings

Differential protein precipitation is a rapid and economical step in protein purification and is based on exploiting the inherent physicochemical properties of the polypeptide. Precipitation of recombinant proteins, lysed from the host cell, is commonly used to concentrate the protein of choice before further polishing steps with more selective purification columns (e.g., His-Tag, Size Exclusion, etc.). Recombinant proteins can also precipitate naturally as inclusion bodies due to various influences during overexpression in the host cell. Although this phenomenon permits easier initial separation from native proteins, these inclusion bodies must carefully be differentially solubilized so as to reform functional, correctly folded …

Conditions Responsible For The Success Of Carnivorous Plants In Nutrient-Poor Wetlands, Matthew John Abbott

Electronic Theses and Dissertations

Despite the vast array of past research focused on carnivorous plants, few studies have investigated the ecological interactions between carnivorous and non-carnivorous plant species. I addressed the following three questions: (1) does niche complementarity promote coexistence between fire-adapted carnivorous and non-carnivorous species? (2) do carnivorous plants rely on both leaf traps and arbuscular mycorrhizal fungi to access different nutrients that are in high demand after fire in nutrient poor bogs? (3) why are carnivorous plants largely absent from nutrient-rich wetlands? I addressed the first question by examining the three-way interacting effects of fire, prey-derived nutrient availability, and root competition from …

A Kinematic Comparison Of Shoulder And Elbow Dynamics Influenced By The Shoe-Surface Interface In Youth And Adolescent Baseball Pitchers, Jacob Richard Gdovin

Electronic Theses and Dissertations

From 1994-2006, 1.5 million baseball injuries were treated within emergency departments across the United States while the upper extremity was the second most commonly injured body part. Although it has been determined that pitch count, pitch type and pitching mechanics are the main contributors to upper extremity pain in baseball pitchers, footwear has not been considered a potential factor. Therefore, the purpose of this study was to determine how baseball-specific footwear [turf shoes (ts) and molded cleats (mc)] affects the shoulder and elbow dynamics of youth and adolescent pitchers during an overhead pitch on various surface inclinations [flat ground (fg) …

The Impact Of Simulated Microgravity On The Growth Of The Model Legume Plant Medicago Truncatula, Gemma Elizabeth Lionheart

Electronic Theses and Dissertations

Simulated microgravity has been a useful tool to help understand plant development in altered gravity conditions. Thirty-one genotypes of the legume plant Medicago truncatula were grown in either simulated microgravity on a rotating clinostat, or a static, vertical environment. Twenty morphological features were measured and compared between these two gravity treatments. Within-species genotypic variation was a significant predictor of the phenotypic response to gravity treatment in 100% of the measured morphological and growth features. In addition, there was a genotype–environment interaction (G×E) for 45% of the response variables, including shoot relative growth rate (p < 0.0005), median number of roots (p ∼ 0.02), and root dry mass (p < 0.005). These findings are discussed in the context of improving future studies in plants space biology by controlling for genotypic differences, and by connecting traits to their underlying genetic causes by using genome-wide association (GWA) mapping. In the long-term, manipulation of genotype effects, in combination with M. truncatula’s symbiotic relationships with rhizobacteria and arbuscular mycorrhizal fungi, will be important for optimizing legumes for cultivation on long-term space missions.

In addition to establishing a standardized method of collecting and characterizing reptile microbiomes I made novel contributions to the future direction of the burgeoning field of host-associated microbiome research. Through persistent and rigorous fieldwork I amassed the largest …

Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds, Matthew Robert Pintar

Electronic Theses and Dissertations

The processes that generate patterns of species diversity within and among habitat patches are a fundamental topic of interest in ecology. Traditionally, there was a focus on post-colonization effects such as predation, however, pre-colonization processes, such as habitat selection, are equally important determinants of community structure. In freshwater systems, the lethal effects of dominant predators (particularly fish) are well established, while the transition from permanent to temporary ponds is a defining characteristic. This transition produces distinct communities characterized by organisms with complex life cycles and plastic developmental strategies. This means that many organisms occupying habitat patches arrive there by the …

Impaired physical functions has been suggested as a limitation on explosive strength, musculoskeletal output, cardiovascular output, and proper technique in contact sports. The purpose of this study was to investigate the relationship between hydration levels and physiological profiles that can be used as a proactive approach in monitoring a collegiate athlete’s athletic performance, fatigue, and recovery status. It was hypothesized that insufficient …

Relationships Between Dietary Habits, Demographics, And Hike Outcome Among 2015 Pacific Crest Trail Backpackers, Lauren Ann Black

Electronic Theses and Dissertations

This quantitative research study explores the relationship between dietary patterns, hiker demographics, and total miles hiked during a backpacking trip on the Pacific Crest Trail (PCT). Long hiking distances, low rate of thru-hike completion, consumption of processed and ready to eat foods, weight loss, and large time and monetary strains are comthemes accepted anecdotally by the backpacking population11. However, these themes have yet to be adequately researched and validated for long distance backpackers and PCT backpackers specifically. The online survey gathered data from 151 backpackers who hiked the PCT in 2015. Significant positive correlational relationships were found between the number …

Biochemical And Molecular Assessment Of Toxicity Of Primaquine Metabolites On Erythrocytes, Jagrati Jain

Electronic Theses and Dissertations

The 8-aminoquinoline (8AQ) antimalarial drug primaquine (PQ) is the only drug for prevention of malaria relapse. Moreover, PQ also has gametocytocidal activity against Plasmodium falciparum. However, clinical use of PQ has been limited due to its hemolytic toxicity, especially in glucose-6-phosphate dehydrogenase deficient (G6PDd) individuals. Phenolic and quinone metabolites generated via cytochrome P450-dependent pathways appear to be responsible for hemolytic effects of PQ. However, the mechanism for the hemolytic toxicity of PQ is still poorly understood. To explore the mechanism, targets, and pathways for toxicity of PQ, normal and G6PDd human erythrocytes were treated with the potential hemotoxic metabolites of …

Nucleic Acid Clamp-Mediated Transcriptional And Translational Modulation Of Oncogenes Via The Stabilization Of G-Quadruplexes, Taisen Hao

Electronic Theses and Dissertations

G-quadruplexes (G4s) are non-canonical secondary nucleic acid structures that exit in various biologically important regions within a cell, such as the promoters of DNA, 5’-Untranslated regions (UTR) of mRNA and telomeres. These secondary structures tend to cluster around 1 kb from transcriptional start sites across all human chromosomes in addition to at telomeric regions. Extensive efforts from many research groups have been dedicated to targeting G4s in oncogenic promoters, telomeres, and 5’-UTRs with traditional small molecules. However, most small molecules recognizing multiple G4s raising potential issues in terms of utilizing these small molecules clinically. Therefore, we developed a novel nucleic …

Historical Refuges And Recolonization Routes In The Southern Appalachian Mountains, Inferred Through Phylogeographic Analysis Of The Spotted Wintergreen (Chimaphila Maculata), John Daniel Banusiewicz

Electronic Theses and Dissertations

Phylogeography has recently benefited from incorporation of coalescent modeling to test competing scenarios of population history of a species. Ecological niche modeling has also been useful in inferring areas of likely suitable habitat during past climate conditions. Several studies have examined the population history of biota in the Southern Appalachian Mountains and how they responded to climate change associated with the end of the Last Glacial Maximum (~18,000 years ago), though few studies have focused on understory plants. This study redressed that knowledge gap thorough examination of the phylogeographic history of the understory plant Chimaphila maculata, which is native to …

Contribution Of Specific Amino Acids To Calcium-Dependent Dimerization Of Epithelial Cadherin, Xiaoyun Z. Howard

Electronic Theses and Dissertations

Cadherins are calcium-dependent molecules that play essential roles in embryonic development, tissue morphogenesis, and cancer progression. Epithelial (E-) cadherin is present at adherens junctions, structures that are important for maintaining tissue integrity. At adherens junctions, cell–cell adhesion complexes are formed as clusters of cadherin dimers through strand-swapped dimerization between two interacting protomers from adherent cells. Recently, a number of studies of dimer formation of E-cadherin supported a two-step adhesive binding model. First, an inter-molecular initial encounter complex (X-dimer) forms at the linker region of the first two extracellular domains, EC1 and EC2. Next, strand-swap dimerization occurs via exchange or ''swap'' …

Bioelectrohydrogenesis And Inhibition Of Methanogenic Activity In Microbial Electrolysis Cells - A Review, Rengasamy Karthikeyan, Ka Yu Cheng, Ammaiyappan Selvam, Arpita Bose, Jonathan W.C. Wong

Biology Faculty Research

Microbial electrolysis cells (MECs) are a promising technology for biological hydrogen production. Compared to abiotic water electrolysis, a much lower electrical voltage (~0.2V) is required for hydrogen production in MECs. It is also an attractive waste treatment technology as a variety of biodegradable substances can be used as the process feedstock. Underpinning this technology is a recently discovered bioelectrochemical pathway known as "bioelectrohydrogenesis". However, little is known about the mechanism of this pathway, and numerous hurdles are yet to be addressed to maximize hydrogen yield and purity. Here, we review various aspects including reactor configurations, microorganisms, substrates, electrode materials, and …

The Red Imported Fire Ant: The Visitor Who Wouldn’T Leave. A Brief Overview Of The Control Of Solenopsis Invicta In The United States, Melissa Brown

Department of Entomology: Distance Master of Science Projects

The ease at which people, plants and animals move across the globe has created the perfect vehicle for transporting pests and disease. The introduction of non-native species into an ecosystem is a cause for great concern. The economic impact alone makes this a situation that effects everyone. The Red Imported Fire Ant, Solenopsis invicta Buren has become a major agricultural and urban pest throughout the southeastern United States. In addition, fire ants cause both medical and environmental harm (Stimac and Alves 1994). The cost associated with the control of the RIFA is significant. An estimated cost of about $36 per …

Rag1 Soybean Photosynthetic Response To Biotype 2 Aphid Colonization And Feeding, Katy Hillard

Department of Entomology: Distance Master of Science Projects

Over the past ten years, the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), has been one of the principal insect threats to commercial soybean, Glycine max (L.) Merr., production in the United States. Resistance genes identified from native soybean have been incorporated into commercial varieties to provide protection against aphid feeding damage. The biology of the pest lends itself to rapid buildup of biotypes capable of overcoming host plant resistance. Single gene resistance sources have displayed low levels of durability against aphids. The first aphid resistant commercial soybean line released in the United States contained the Rag1 gene, which was …
