The Role Of Tumor Suppressor Dear1 In The Acquisition Of Mammary Stem/Progenitor Cell Properties, Uyen Le
The Role Of Tumor Suppressor Dear1 In The Acquisition Of Mammary Stem/Progenitor Cell Properties, Uyen Le
Dissertations & Theses (Open Access)
Breast cancer is the most commonly diagnosed cancer in women in America. Ductal carcinoma in situ (DCIS), one of the earliest pre-invasive forms of invasive ductal carcinoma (IDC), has a 30-50% risk of progressing to IDC. Understanding the mechanisms regulating progression from DCIS to IDC would help identify biomarkers to stratify patients at higher risk of progression or metastasis. Cumulative literature suggests the earliest phase of dissemination from the primary tumor is driven by the epithelial-mesenchymal transition (EMT) program. DEAR1 is a tumor suppressor gene which is mutated, undergoes loss of heterozygosity in breast cancer, and is downregulated in DCIS …

Linkage Mapping For Soybean (Glycine Max) Flood Tolerance, Wade Stiles Hummer
Graduate Theses and Dissertations
Flood tolerance in soybean (Glycine max) is not a well-characterized trait, yet flooding damage is second only to drought stress in terms of yield reduction. The objectives of this study were to determine genetic variation for flooding tolerance in two populations of soybean recombinant inbred lines (RILs) and to identify and confirm flood tolerant QTL. Population A (WHA) consisted of 111 RILs derived from the cross 5002T by 91210-350 and Population B (WHB) consisted of 79 RILs from the cross RA-452 by Osage. Experiments were conducted at the Rice Research and Extension Center (RREC) near Stuttgart, AR in 2015 and …

© 2018, The Author(s). Cigarette smoking alters the oral microbiome; however, the effect of alternative tobacco products remains unclear. Middle Eastern tobacco products like dokha and shisha, are becoming globally widespread. We tested for the first time in a Middle Eastern population the hypothesis that different tobacco products impact the oral microbiome. The oral microbiome of 330 subjects from the United Arab Emirates Healthy Future Study was assessed by amplifying the bacterial 16S rRNA gene from mouthwash samples. Tobacco consumption was assessed using a structured questionnaire and further validated by urine cotinine levels. Oral microbiome overall structure and specific taxon …
Evaluation Of Genetic And Environmental Influences On Broiler Meat Quality, Sara Katherine Orlowski
Evaluation Of Genetic And Environmental Influences On Broiler Meat Quality, Sara Katherine Orlowski
Graduate Theses and Dissertations
The effect of both genetic and environmental influences on broiler meat quality were evaluated over three experiments. Selection response was assessed for broiler lines selected for high (HBY4) and low (LBY4) four day percentage breast yield which were formed from a random bred control (RAN). A modern random bred population (MRB) created in 2015 was evaluated for differences in 4 day percentage breast yield and the resulting differences in the incidence and severity of the woody breast and white striping myopathies. Additionally, the use of embryonic thermal manipulation to impact cell division and early caloric feed restriction to slow growth …
Genome Wide Association Studies For Identification Of Markers Linked To Sucrose Traits In Sugarcane, Nathanael Darrell Fickett
Genome Wide Association Studies For Identification Of Markers Linked To Sucrose Traits In Sugarcane, Nathanael Darrell Fickett
LSU Doctoral Dissertations
Sugarcane, being a complex aneu-polyploid, poses unique challenges to fine mapping of quantitative trait loci (QTL) controlling agronomic traits of interest. Genome-wide association studies (GWAS) could be a better alternative to identify molecular markers associated with specific traits due to high linkage disequilibrium in sugarcane. In the first study, marker-trait associations (MTAs) were evaluated for three sucrose traits, Brix, total recoverable sugar (TRS), and percent sucrose on 48 elite and historic Louisiana breeding clones using 1,062 alleles. These sucrose traits were highly correlated (P-value < 0.0001) at >0.96. TASSEL 5.1 and JMP Genomics 8.0 were compared with eight models run in each program. …
Effects Of Evolution On Laboratory Sublines Of Myxococcus Xanthus Dk1622, Mackenzie Ryan, Francesca Scribano, Kimberly Murphy
Effects Of Evolution On Laboratory Sublines Of Myxococcus Xanthus Dk1622, Mackenzie Ryan, Francesca Scribano, Kimberly Murphy
Celebration of Learning
Microbes have served as effective models for studying evolution because of their ability to be easily replicated, stored, and manipulated. Myxococcus xanthus is a soil bacterium that has served as a model organism in many laboratories. The unique social and motile behaviors exhibited by this bacterium make it ideal for phenotypic assays. A wild-type strain of M. xanthus, DK1622, has been distributed to laboratories across the United States and therefore we now have DK1622 sublines. The genomes of a number of these sublines have been sequenced and their social and motile phenotypes have been analyzed. When nine of these sublines …

Re-Thinking Alzheimer's Disease Therapeutic Targets Using Gene-Based Tests, Man Ki Kwok, Shi Lin Lin, C Mary Schooling
Publications and Research
Background: Alzheimer's disease (AD) is a devastating condition with no known effective drug treatments. Existing drugs only alleviate symptoms. Given repeated expensive drug failures, we assessed systematically whether approved and investigational AD drugs are targeting products of genes strongly associated with AD and whether these genes are targeted by existing drugs for other indications which could be re-purposed.
Methods: We identified genes strongly associated with late-onset AD fromthe loci of genetic variants associated with AD at genome-wide-significance and from a gene-based test applied to the most extensively genotyped late-onset AD case (n=17,008)-control (n=37,154) study, the International Genomics of Alzheimer's Project. …

The Influence Of Tissue Plasminogen Activator I/D Polymorphism On The Tpa Response To Exercise, Adam M. Coughlin
International Journal of Exercise Science
International Journal of Exercise Science 11(3): 1136-1144, 2018. The purpose was to determine if the Alu-insertion (I)/deletion (D) polymorphism of the tissue plasminogen activator (tPA) gene influences the tPA response to maximal exercise. Fifty male subjects (age = 23.6 ± 4.7 yrs) completed a maximal treadmill exercise test. Blood samples were drawn before and immediately after exercise for determination of plasma tPA antigen and activity. Isolated DNA was amplified via polymerase chain reaction, electrophoresed, and visually amplified to determine tPA genotype. Subjects were classified as possessing the D allele (D) (n = 28) or being homozygous for the I allele …

Marine & Environmental Sciences Faculty Articles
Sargassum species play key ecological roles on coral reefs, yet their diversity remains poorly known. Precise identification of Sargassum species, however, is improving with molecular genetic tools, though these have yet to be applied rigorously in Singapore. Historical records list 41 species, but no more than ten were verified based on herbarium vouchers, and even fewer (five species) were confirmed in the field based on a single nuclear gene marker in a previous study. Here, we revised the diversity of Sargassum in Singapore by examining all the morphologically distinct forms collected from the local coral reef environment. A total of …

Random Genetic Drift And Selective Pressures Shaping The Blattabacterium Genome, Austin Alleman, Kate L. Hertweck, Srini Kambhampati
Biology Faculty Publications and Presentations
Estimates suggest that at least half of all extant insect genera harbor obligate bacterial mutualists. Whereas an endosymbiotic relationship imparts many benefits upon host and symbiont alike, the intracellular lifestyle has profound effects on the bacterial genome. The obligate endosymbiont genome is a product of opposing forces: genes important to host survival are maintained through physiological constraint, contrasted by the fixation of deleterious mutations and genome erosion through random genetic drift. The obligate cockroach endosymbiont, Blattabacterium – providing nutritional augmentation to its host in the form of amino acid synthesis – displays radical genome alterations when compared to its most …
Confirming World-Wide Distribution Of An Agriculturally Important Lacewing, Chrysoperla Zastrowi Sillemi, Using Songs, Morphology, Mitochondrial Gene Sequencing, And Phylogenetic Reconstruction, Zoe Mandese
Honors Scholar Theses
The Chrysoperla carnea-group of green lacewings is a cryptic species complex. Species within the group are morphologically similar, yet isolated from one another via reproductive mating song. Chrysoperla zastrowi, a species within the carnea-group, is currently described with a distribution ranging from South Africa to the Middle East and India. However, recent collections of carnea-group lacewings from Guatemala and California were preliminarily identified as Chrysoperla zastrowi based upon similarities in their vibrational courtship songs. This analysis aims to place six specimens, collected by collaborators in Guatemala, Armenia, Iran, and California, into a pre-existing phylogeny of the …
Genetics Of A De Novo Origin Of Undifferentiated Multicellularity, Matthew D. Herron, William C. Ratcliff, Jacob Boswell, Frank Rosenzweig
Genetics Of A De Novo Origin Of Undifferentiated Multicellularity, Matthew D. Herron, William C. Ratcliff, Jacob Boswell, Frank Rosenzweig
Biological Sciences Faculty Publications
The evolution of multicellularity was a major transition in evolution and set the stage for unprecedented increases in complexity, especially in land plants and animals. Here, we explore the genetics underlying a de novo origin of multicellularity in a microbial evolution experiment carried out on the green alga Chlamydomonas reinhardtii. We show that large-scale changes in gene expression underlie the transition to a multicellular life cycle. Among these, changes to genes involved in cell cycle and reproductive processes were overrepresented, as were changes to C. reinhardtii-specific and volvocine-specific genes. These results suggest that the genetic basis for the experimental evolution …
Eco-Evolutionary Implications Of Environmental Change Across Heterogeneous Landscapes, Jared J. Homola
Eco-Evolutionary Implications Of Environmental Change Across Heterogeneous Landscapes, Jared J. Homola
Electronic Theses and Dissertations
Species use a variety of mechanisms to adapt to environmental change. These range from spatially tracking optimal environments, to phenotypically plastic responses and evolutionary adaptation. Due to increases in anthropogenic influence on environments, characteristics of change such as their duration and magnitude are undergoing fundamental shifts away from the natural disturbance regimes that shaped species’ evolution. This dissertation uses empirical data and simulation models to examine the ecological and evolutionary consequences of environmental change across real, heterogeneous landscapes for multiple species, with an emphasis on anthropogenic changes. I used landscape genetics to evaluate the effects of urbanization on two native …

The Summer Undergraduate Research Fellowship (SURF) Symposium
Bacteriophage are viruses that infect and kill bacteria. They can be used as treatments for antibiotic resistant bacterial infections, but more knowledge is needed about phage and how they interact with bacteria in order to develop safe and effective phage therapy treatments. This study examines the genomes of eighteen mycobacteriophage that were isolated from the environment on and surrounding Purdue University. Phage genomes were annotated using several bioinformatics software, including DNA Master, GeneMark, and PECAAN. Evidence was examined to determine the correct location within the genome and the potential function. Approximately two thousand genes were annotated in this study. A …
Hpa Axis Genetic Variation And Life Stress Influences On Functional Connectivity In Resting State Networks, Tara Ann Miskovich
Hpa Axis Genetic Variation And Life Stress Influences On Functional Connectivity In Resting State Networks, Tara Ann Miskovich
Theses and Dissertations
Stressful or traumatic experiences are a key risk factor for developing psychopathology, primarily through the impact that chronic stress has on hypothalamic-pituitary-adrenal (HPA) axis functioning. The HPA axis regulates the stress response but can become dysregulated with chronic activation and impact brain functioning. In addition to environmental stressors, genetic variation in genes in the HPA axis appear to influence HPA axis functioning and is also related to disruption in brain functioning, particularly in the context of high life stress. The current study focused on examining potential mechanisms through which trauma and stress interacts with HPA axis genes to impact key …
Structural And Functional Brain Connectivity In Middle-Aged Carriers Of Risk Alleles For Alzheimer's Disease, Laura Korthauer
Structural And Functional Brain Connectivity In Middle-Aged Carriers Of Risk Alleles For Alzheimer's Disease, Laura Korthauer
Theses and Dissertations
Single nucleotide polymorphisms (SNPs) in APOE, COMT, BDNF, and KIBRA have been associated with age-related memory performance and executive functioning as well as risk for Alzheimer’s disease (AD). The purpose of the present investigation was to characterize differences in brain functional and structural integrity associated with these SNPs as potential endophenotypes of age-related cognitive decline. I focused my investigation on healthy, cognitively normal middle-aged adults, as disentangling the early effects of healthy versus pathological aging in this group may aid early detection and prevention of AD. The aims of the study were 1) to characterize SNP-related differences in functional connectivity …
Molecular Survey For The Honey Bee Trypanosome Parasites Crithidia Mellificae And Lotmaria Passim, Mary-Kate Williams
Molecular Survey For The Honey Bee Trypanosome Parasites Crithidia Mellificae And Lotmaria Passim, Mary-Kate Williams
Graduate Theses and Dissertations
Honey bee populations have been fluctuating within recent years. No one cause has been attributed to colony fluctuations due to the theory that multiple stressors interact with one another to impact colony health. Consequently, microorganisms such as internal parasites of honey bees have been understudied as a contributor to colony health decline.
Molecular diagnostics were utilized to detect the presence of two honey bee trypanosome parasites, Crithidia mellificae and Lotmaria passim, in managed and feral honey bee populations from eight states in the United States (USA). Because studies on trypanosome infections are lacking in the USA, it is important to …
Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning
Investigation Of Bacterial Taxa As Biomarkers Of Fescue Toxicosis And Heat Stress In Grazing Beef Cows, Sarah Katherine Chewning
Graduate Theses and Dissertations
Fescue toxicosis in grazing beef cattle is caused by consumption of Ergot alkaloids associated with tall fescue (toxic fescue) and is responsible for substantial economic loss to the U.S. beef industry. Cattle consuming toxic fescue suffer adverse physiological responses, such as: hyperthermia, increased respiration rate (RR), poor reproduction and growth performance. Other adverse responses to fescue toxins include the retention of a winter hair coat and vasoconstriction in the extremities, which can lead to tissue necrosis. Identifying cattle with reduced susceptibility to fescue toxins would allow for efficient use of fescue pastures; thus, the objectives of this thesis was to: …
Adam And Eve, Designed Diversity, And Allele Frequencies, John C. Sanford, Robert W. Carter, Wes Brewer, John Baumgardner, Bruce Potter, Jon Potter
Adam And Eve, Designed Diversity, And Allele Frequencies, John C. Sanford, Robert W. Carter, Wes Brewer, John Baumgardner, Bruce Potter, Jon Potter
Proceedings of the International Conference on Creationism
Theistic evolutionists present multiple genetic arguments against a literal Adam and Eve. One key argument asserts it would be impossible for a single human couple to give rise to the genetic diversity seen in the modern human population. This implicitly assumes Adam and Eve would have been created without internal genetic diversity. If this were true, all observed variations would have to arise recently via random mutations. This would require incredibly high mutation rates, logically leading to rapid extinction.
Yet, Adam and Eve could have been created massively heterozygous. We have argued for over a decade that they could have …

Genomic Variation Of Introduced Salvinia Minima In Southeastern United States, Carol A. Rowe, Donald P. Hauber, Paul G. Wolf
Ecology Center Publications
Common salvinia, Salvinia minima Baker (Salviniaceae), is a small, floating aquatic fern native to Central and South America that has invaded fresh water bodies in southeastern United States since the 1930s. We examined genetic variation across much of the introduced range of this species in the United States using codominant RAD-seq markers. Data from over 600 variable loci showed a reduction in heterozygosity from east to west in addition to a corresponding trend in assignment of samples to one of two genetic groups. Our data are consistent with previous published work and with the hypothesis that common salvinia had a …
Utilizing Random Regression Models For Genomic Prediction Of A Longitudinal Trait Derived From High‐Throughput Phenotyping, Malachy T. Campbell, Harkamal Walia, Gota Morota
Utilizing Random Regression Models For Genomic Prediction Of A Longitudinal Trait Derived From High‐Throughput Phenotyping, Malachy T. Campbell, Harkamal Walia, Gota Morota
Department of Agronomy and Horticulture: Faculty Publications
The accessibility of high‐throughput phenotyping platforms in both the greenhouse and field, as well as the relatively low cost of unmanned aerial vehicles, has provided researchers with an effective means to characterize large populations throughout the growing season. These longitudinal phenotypes can provide important insight into plant development and responses to the environment. Despite the growing use of these new phenotyping approaches in plant breeding, the use of genomic prediction models for longitudinal phenotypes is limited in major crop species. The objective of this study was to demonstrate the utility of random regression (RR) models using Legendre polynomials for genomic …
Genetic Basis For Elevated Rheumatic Heart Disease Susceptibility In Samoa, John Bowen Allen
Genetic Basis For Elevated Rheumatic Heart Disease Susceptibility In Samoa, John Bowen Allen
Theses and Dissertations
Rheumatic heart disease is an inflammatory heart disease that affects millions of people around the world. Especially high rates of the disease can be found in Oceania, including the island nation of Samoa. Genetic studies of immune response genes have provided insight into a possible genetic link to increased susceptibility to rheumatic heart disease, including the genes that code for the toll-like receptor (TLR) protein family. One of the functions of TLR proteins is to recognize the presence of bacteria via identification of bacterial flagella. My evaluation of a Samoan family identified a variant in the TLR-5 gene that would …

Light-Induced Expression Of A Blue Coral Protein In An Industrial Fungus, Lindsay Tomczak
Honors Theses
The ultimate goal of this research project is to improve the growth and structural characteristics of an Ecovative Design LLC (Green Island, NY) production strain to produce commercial biomaterials for packaging. These biomaterials are produced from renewable resources and can be easily broken down after they fulfill their purpose, unlike the commonly used materials today (such as Styrofoam). In an effort to quantify the light-reactivity of the fungus, a codon-optimized DNA sequence coding a blue chromoprotein was introduced and utilized as a visual reporter gene. Transcriptional controlling sequences were identified from orthologs to specific light-regulated genes and were combined with …

Sequencing And Analysis Of Centromere Protein B In Wallaby And The Rapid Evolution Of The Centromere, Alexander Tedeschi
Sequencing And Analysis Of Centromere Protein B In Wallaby And The Rapid Evolution Of The Centromere, Alexander Tedeschi
Honors Scholar Theses
Using a combination of Sanger sequencing and RNA-seq data, this project aims to determine the nucleotide and amino acid sequence of Centromere Protein B (CENP-B), an important protein involved in the assembly of the kinetochore protein complex at the centromere, in several species of marsupials, specifically wallabies. Despite their recent evolutionary history, these species have been shown to have surprisingly divergent centromeric DNA sequences. Through comparative analysis of these sequences, this project, along with analysis of several other CENPs, aims to determine if this divergence extends to the proteins closely associated with these sequences and possibly even further into the …

Crispr Gene Editing In The Sea Squirt, Ciona Intestinalis, Evelyn Siler, Steven Irvine
Senior Honors Projects
Genetic manipulation has come a long way in the past ten years alone. Scientists have had access to gene editing techniques for decades, but until recently these methods have proven to be expensive and unpredictable. However, thanks to the development of a new, more efficient genome editing strategy called CRISPR/Cas9, more aggressive progress can now be made in genetics research.
CRISPR is not a machine or a physical tool, but rather it is a system that involves introducing a protein into a cell, along with a DNA segment that will attract the protein to a desired location on the DNA. …

In recent years, advancements in genetic testing methods have revolutionized the medical field by enhancing the ability to identify persons with an inherited predisposition to cancer. According to the American Society for Clinical Oncology, individuals should undergo genetic testing when he or she meets the following criteria: the individual demonstrates familial history that indicates a predisposition to certain cancers, the test can be adequately interpreted, and the results will aid in the diagnosis, treatment, or management of the patient or additional family members at risk. Genetic testing can be done on samples of hair, skin, blood, amniotic fluid, or other …
Genetic Testing Practices Of Genetic Counselors, Geneticists, And Pediatric Neurologists With Regard To Childhood-Onset Neurogenetic Conditions, Sara Wofford
Dissertations & Theses (Open Access)
Identifying genetic diagnoses for neurological conditions with a considerable hereditary component, such as autism spectrum disorder (ASD), intellectual disability, and epilepsy, is critical to providing proper medical management for these patients and their families. However, many patients with these conditions are not tested appropriately or receive no genetic testing at all. The current study was designed to characterize the genetic testing practices of the providers most likely to evaluate or order genetic testing for these patients: pediatric neurologists, geneticists, and genetic counselors. The study noted significant variance between the testing strategies selected by pediatric neurologists compared to those of geneticists …
