Understanding The Impacts Of Current And Future Environmental Variation On Central African Amphibian Biodiversity, Courtney A. Miller
Understanding The Impacts Of Current And Future Environmental Variation On Central African Amphibian Biodiversity, Courtney A. Miller
University of New Orleans Theses and Dissertations
Global climate change is projected to impact multiple levels of biodiversity by imposing strong selection pressures on existing populations, triggering shifts in species distributions, and reorganizing entire communities. The Lower Guineo-Congolian region in central Africa, a reservoir for amphibian diversity, is predicted to be severely affected by future climate change through rising temperatures and greater variability in rainfall. Geospatial modelling can be used to assess how environmental variation shapes patterns of biological variation – from the genomic to the community level – and use these associations to predict patterns of biological change across space and time. The overall goal of …
Power In Pairs: Assessing The Statistical Value Of Paired Samples In Tests For Differential Expression, John R. Stevens, Jennifer S. Herrick, Roger K. Wolff, Martha L. Slattery
Power In Pairs: Assessing The Statistical Value Of Paired Samples In Tests For Differential Expression, John R. Stevens, Jennifer S. Herrick, Roger K. Wolff, Martha L. Slattery
Mathematics and Statistics Faculty Publications
Background: When genomics researchers design a high-throughput study to test for differential expression, some biological systems and research questions provide opportunities to use paired samples from subjects, and researchers can plan for a certain proportion of subjects to have paired samples. We consider the effect of this paired samples proportion on the statistical power of the study, using characteristics of both count (RNA-Seq) and continuous (microarray) expression data from a colorectal cancer study.
Results: We demonstrate that a higher proportion of subjects with paired samples yields higher statistical power, for various total numbers of samples, and for various strengths of …

Population Genomics And Phylogeography Of A Benthic Coastal Shark (Scyliorhinus Canicula) Using 2b-Rad Single Nucleotide Polymorphisms, Alice Manuzzi, Lorenzo Zane, Antonio Munoz-Merida, Andrew M. Griffiths, Ana Verissimo
VIMS Articles
The existence of strong genetic structure is expected in species with limited ability to disperse and philopatric behaviour. These life-history traits are found in many small benthic elasmobranchs, such as in the small-spotted catshark (Scyliorhinus canicula). However, no evidence of genetic structure was found across its northeastern Atlantic (NEA) range using traditional molecular markers. Here, fine-scale genetic differentiation was detected between the British Isles and southern Iberia using 2674 single nucleotide polymorphism loci generated using 2b-restriction site-associated DNA (2b-RAD). Geographical distance and historical demography were two major drivers shaping the distribution of genetic diversity of S. canicula along …
Physella Acuta, Comparative Immunology And Evolutionary Aspects Of Gastropod Immune Function, Jonathan H. Schultz
Physella Acuta, Comparative Immunology And Evolutionary Aspects Of Gastropod Immune Function, Jonathan H. Schultz
Biology ETDs
Gastropod immunobiology has benefitted from investigations focused on the planorbid snail Biomphalaria glabrata, intermediate host for the human parasite Schistosoma mansoni. Though such concentrated efforts have elucidated fascinating aspects of invertebrate immunity, they have not provided full knowledge regarding the evolution of immune function among other gastropod species. This dissertation presents the importance of making strategic choices regarding which organisms to select for comparative immunology. Herein, the choice was made to investigate the immunobiology of Physella acuta, a freshwater snail species of the Physidae, a sister family to Planorbidae to which B. glabrata belongs. Benefiting greatly from …
Genetic Evolution And Prognostic Determinants Of Pancreatic Cancer On Longitudinal Liquid Biopsies, Vincent Bernard
Genetic Evolution And Prognostic Determinants Of Pancreatic Cancer On Longitudinal Liquid Biopsies, Vincent Bernard
Dissertations & Theses (Open Access)
Pancreatic ductal adenocarcinoma (PDAC) has one of the lowest 5-year survival rates amongst solid tumors. As early detection of PDAC is unusual and typically incidental, most patients present with locally advanced and metastatic disease where effective therapeutic strategies remain a significant unmet need. Specifically, surrogate biomarkers for tumor monitoring of PDAC may lead to improved elucidation of clinical actionability and prognostic potential. On the other hand, tumor tissue is rarely sampled in patients presenting with de novo or recurrent metastatic PDAC, apart from a fine needle aspiration or a core needle biopsy performed for diagnosis. This precludes the opportunity for …

IMPROVING dbNSFP
Mingyao Lu, B.S.
Advisory Professor: Xiaoming Liu, Ph.D.
The analysis and interpretation of DNA variation are very important for the Whole Exome studies (WES). Genome research has focused on single nucleotide variants (SNVs). Since indels are as important as SNVs, especially indels in coding regions are often candidates of disease-causing variants, thus, it is necessary to expand the focus to include indel mutations.
The goal of my project is to provide an automatic annotation pipeline to the WES based disease studies project by extending the dbNSFP with a tool for automated indel annotation and deleteriousness prediction. The current …

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. …
Genome-Wide Screening Identifies Genes And Biological Processes Implicated In Chemoresistance And Oncogene-Induced Apoptosis, Tengyu Ko
LSU Doctoral Dissertations
Anti-proliferative responses such as senescence and apoptosis are often used by normal cells to combat oncogenic insults and to prevent tumorigenesis. However, oncogenic mutations are frequently found in cancers, suggesting that additional mutations may occur to facilitate the bypass of these anti-proliferative responses. It is believed that some of these additional mutations may also contribute to the chemoresistance of cancers. This dissertation focused on identifying novel genes and biological processes implicated in chemoresistance and tumorigenesis.
Cisplatin-based chemotherapeutic regimens are frequently used for treatments of solid tumors. However, tumor cells may have inherent or acquired resistance to cisplatin, and the underlying …

Identification And Characterization Of Nitrogen Fixing Bacteria Associated With Kudzu Root Nodules, Chasity Lawless, Michelle Zedonek, Debbie Curtis, Jonda Scharringhausen, Jared Bryant, Wendy A. Dustman, Alexandra M. Kurtz, Bekah Ward Dr.
Georgia Journal of Science
Pueraria montana, better known as kudzu, is an invasive species rapidly spreading throughout the southeastern United States. This plant can form root nodules which house nitrogen-fixing bacteria, allowing atmospheric nitrogen to be converted into biologically available forms of nitrogen for use by the plant host. Given the centrality of these bacteria to the spread of kudzu, isolates from nodules were characterized after collection from seven different locations across the metropolitan Atlanta area. Twenty-five isolates were grown on two different variants of nitrogen free media. Four different carbon sources were evaluated as well. Finally, growth under both aerobic and anaerobic …

Bioinformatics Faculty Publications
For many complex traits, gene regulation is likely to play a crucial mechanistic role. How the genetic architectures of complex traits vary between populations and subsequent effects on genetic prediction are not well understood, in part due to the historical paucity of GWAS in populations of non-European ancestry. We used data from the MESA (Multi-Ethnic Study of Atherosclerosis) cohort to characterize the genetic architecture of gene expression within and between diverse populations. Genotype and monocyte gene expression were available in individuals with African American (AFA, n = 233), Hispanic (HIS, n = 352), and European (CAU, n = 578) ancestry. …

The Transcriptome Of The Bermuda Fireworm Odontosyllis Enopla (Annelida: Syllidae): A Unique Luciferase Gene Family And Putative Epitoky-Related Genes, Mercer R. Brugler, M. Teresa Aguado, Michael Tessler, Mark Siddall
Publications and Research
The Bermuda fireworm Odontosyllis enopla exhibits an extremely tight circalunar circadian behavior that results in an impressive bioluminescent mating swarm, thought to be due to a conventional luciferase-mediated oxidation of a light-emitting luciferin. In addition, the four eyes become hypertrophied and heavily pigmented, and the nephridial system is modified to store and release gametes and associated secretions. In an effort to elucidate transcripts related to bioluminescence, circadian or circalunar periodicity, as well as epitoky-related changes of the eyes and nephridial system, we examined the transcriptomic profile of three female O. enopladuring a bioluminescent swarm in Ferry Reach, Bermuda. …
Microrna Functions In Uv-Induced Cutaneous Squamous Cell Carcinoma, Tran Nguyen
Microrna Functions In Uv-Induced Cutaneous Squamous Cell Carcinoma, Tran Nguyen
Dissertations & Theses (Open Access)
Cutaneous squamous cell carcinoma (cuSCC) is the second most common skin cancer, for which long term UV exposure and chronic wounding are the dominant risk factors. Despite these clinically established connections, little is understood about the early molecular response of human skin to UV exposure and its connection to acute wounding and cuSCC. Thus, our goal is to find common and specific signatures driven by UV-exposure and wounding as a means of developing new approaches for treating and preventing cuSCC.
Here, we perform integrated analyses of RNA-seq and miR-seq on 3 datasets: (1) UV-unexposed and acute UV-exposed human skin, (2) …
Insight Into Translational Activation In Yeast Mitochondria, Julia Lynn Jones
Insight Into Translational Activation In Yeast Mitochondria, Julia Lynn Jones
Graduate School of Biomedical Sciences Theses and Dissertations
Mitochondrial function depends on over a thousand proteins, of which the majority are nuclear DNA-encoded and approximately one percent are mitochondrial DNA-encoded. The mitochondrial DNA of Saccharomyces cerevisiae contains eight protein-encoding genes, seven of which are required for proper function of the respiratory complexes and one encodes a ribosomal protein. The bigenomic nature of the oxidative phosphorylation complexes requires coordinated expression and regulation from both the nuclear and the mitochondrial genomes. It is currently unclear how this regulatory network operates. However, it is thought that nuclear genome-encoded messengers localized to the mitochondria aid in this coordination.
A family of proteins …
Omics Approaches To Uncover Germline And Somatic Variation Underlying Inherited Sarcomagenesis, Justin Wong
Omics Approaches To Uncover Germline And Somatic Variation Underlying Inherited Sarcomagenesis, Justin Wong
Dissertations & Theses (Open Access)
Sarcomas are rare mesenchymal tumors, making up 15% of all childhood and 1% of all adult tumors. They account for a disproportionate share of mortality in young adults, and if left untreated, are highly likely to metastasize. However, sarcoma etiology is poorly understood, and having numerous histological subtypes has complicated elucidation. To better understand factors underlying sarcomagenesis, we leveraged two rare inherited cancer predisposition syndromes, Li-Fraumeni Syndrome (LFS), and LFS-like (LFSL), both with a high incidence of sarcomas. LFS is caused by mutations in the tumor suppressor gene TP53 (p53), but has variable and incomplete penetrance, suggesting additional acquired …

Genomic And Transcriptomic Landscape Of Colorectal Premalignancy, Kyle Chang
Dissertations & Theses (Open Access)
Colorectal cancer (CRC) is the third most commonly diagnosed cancer among men and women in the United States, with 3 to 5 percent of the cases diagnosed in the background of a hereditary form of the disease. Biologically, CRC is divided into two groups: microsatellite instable (MSI) and chromosomally unstable (CIN). Genomic and transcriptomic characterization of CRC has emerged from large-scale studies in recent years due to the advancement of next-generation sequencing technologies. These studies have identified key genes and pathways altered in CRC and provided insights to the discovery of therapeutic targets. Despite the wealth of knowledge acquired in …
Combinatorial Genomic Data Refute The Human Chromosome 2 Evolutionary Fusion And Build A Model Of Functional Design For Interstitial Telomeric Repeats, Jeffrey P. Tomkins
Combinatorial Genomic Data Refute The Human Chromosome 2 Evolutionary Fusion And Build A Model Of Functional Design For Interstitial Telomeric Repeats, Jeffrey P. Tomkins
Proceedings of the International Conference on Creationism
Evolutionists allege that human chromosome 2 is the product of an ancient fusion event in an ancient hominid ancestor descended from apes. However, both the alleged site of fusion and the so-called cryptic centromere of human chromosome 2 are situated inside active genes negating the idea of fusion. Not only are the alleged genomic fossils of fusion representative of functional intragenic sequence, but they are also both highly degenerate versions of their supposed evolutionary beginnings, suggesting something other than an evolutionary origin. Given that these data strongly refute an evolutionary fusion scenario, it behooves creationists to propose an alternative model …
Genomic Signatures Of Adaptive Evolution, Jessica Weber
Genomic Signatures Of Adaptive Evolution, Jessica Weber
Biology ETDs
Comparative genomics has revolutionized virtually all fields of biology including the study of evolution. In this dissertation, I used next-generation sequencing to explore the evolutionary histories and adaptive evolution of a diverse set of taxa. Comparisons ranged across time scales, from population-level genetic diversity studies to questions spanning the deepest branches of the metazoan lineage. Whole genome sequencing of 50 unrelated Korean individuals revealed that Koreans have a distinct genetic history from the Chinese and Japanese populations. Our Korean-specific variome database was used to identify novel disease-causing variants in the Korean population, highlighting the value of high-quality ethnic variation databases …

The antibiotic-resistant bacterium Paenibacillus larvae is the causative agent of American foulbrood (AFB), currently the most destructive bacterial disease in honeybees. Phages that infect P. larvae were isolated as early as the 1950s, but it is only in recent years that P. larvae phage genomes have been sequenced and annotated. In this study we analyze the genomes of all 48 currently sequenced P. larvae phage genomes and classify them into four clusters and a singleton. The majority of P. larvaephage genomes are in the 38–45 kbp range and use the cohesive ends (cos) DNA-packaging strategy, while a minority have genomes …

Transcriptomics Of Learning, Pablo Iturralde
Theses
Learning is a basic and important component of behavior yet we have very little empirical information about the interaction between mechanisms of learning and evolution. In our work, we are testing hypotheses about the neurogenetic mechanisms through which animal learning abilities evolve. We are able to test this directly by using experimentally evolved populations of flies, which differ in learning ability. These populations were previously evolved within the lab by creating worlds with different patterns of change following theoretically predicted effects on which enhanced learning will evolve. How has evolution acted to modulate genes and gene expression in the brain …
Species Distribution And Conservation Genetics Of The Upland And Midland Chorus Frogs (Pseudacris) In Kentucky, Tucker Cambridge
Species Distribution And Conservation Genetics Of The Upland And Midland Chorus Frogs (Pseudacris) In Kentucky, Tucker Cambridge
Masters Theses & Specialist Projects
The upland (Pseudacris feriarum) and midland (P. triseriata) chorus frogs are closely related cryptic species that are best distinguished genetically. The distribution of these species within the Commonwealth of Kentucky has previously been defined by only a handful of genetic samples, making delineation of range limits for each species difficult. Accurate understanding of species distributions, and the genetic structure within them, are vitally important for conservation management of amphibian species. In this study, I have collected genetic samples from across the putative ranges of P. triseriata and P. feriarum in Kentucky and used next-generation sequencing technology to generate more fine-scale …
Inference And Analysis Of Multilayered Mirna-Mediated Networks In Cancer, Duc Do
Inference And Analysis Of Multilayered Mirna-Mediated Networks In Cancer, Duc Do
Dissertations (1934 -)
MicroRNAs (miRNAs) are small noncoding transcripts that can regulate gene expression, thereby controlling diverse biological processes. Aberrant disruptions of miRNA expression and their interactions with other biological agents (e.g., coding and noncoding transcripts) have been associated with several types of cancer. The goal of this dissertation is to use multidimensional genomic data to model two different gene regulation mechanisms by miRNAs in cancer. This dissertation results from two research projects. The first project investigates a miRNA-mediated gene regulation mechanism called competing endogenous RNA (ceRNA) interactions, which suggests that some transcripts can indirectly regulate one another's activity through their interactions with …
