An Extensive Exploration Of Generalist Microbotryum Species Through Host Interactions., Emilee Walters

College of Arts & Sciences Senior Theses

The Microbotryum species complex is a group of fungi, commonly known as anther smuts. Anther smuts are plant parasites that must invade a host plant in order to fulfill their life cycle. As the Microbotryum fungus grows, it sterilizes the host plant, such that infected plants produce fungal teliospores instead of pollen on the male reproductive organs and female reproductive structures do not mature. Microbotryum usually exists as a specialist species, however, there is evidence that several species of anther smuts can exist as generalist species. Comparisons of the infection process and the resulting response of both parasite and host …

Delineating Genetic Influences On Neurodegenerative Disorders And Infectious Diseases Through Advanced Computational Methods, Xiaowei Zhuang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Genetics plays a critical role in understanding the molecular mechanisms underlying neurodegenerative disorders and pathogen evolution in infectious diseases. For example, identifying genetic variants associated with a disease phenotype uncovers functional pathways that could lead to potential drug targets and therapeutic interventions. In addition, tracking the genetic evolution of pathogens enables early detection and warning of infectious disease outbreaks. In both applications, given the large amount of genetic data, advanced computational methods, including longitudinal and multivariate models, could significantly boost the statistical power and capture interrelationships among traits, environmental factors and genetic influences. This dissertation focuses on four applications of …

Timigp: A Computational Framework To Determine The Tumor Immune Microenvironment Associated With Prognosis And Immunotherapy Response, Chenyang Li

Dissertations and Theses (Open Access)

Accumulating evidence has suggested that the tumor immune microenvironment (TIME) drastically impacts cancer patients’ clinical outcomes, including prognosis and immunotherapy response. However, understanding TIME remains challenging due to its complexity and heterogeneity. In this dissertation, we introduce TimiGP (Tumor Immune Microenvironment Illustration based on Gene Pairs), a computational framework designed to address this challenge. Leveraging single-cell RNA-seq (scRNA-seq) and bulk gene expression data alongside clinical information, TimiGP constructs a cell-cell interaction network that elucidates the relationship between immune cell function and relevant clinical outcomes, such as prognosis and treatment response. With immunological insights, these cell-cell interactions also facilitate the development …

The Role Of Wt1 In Müllerian Duct Development, Jace Aloway

Dissertations and Theses (Open Access)

WT1 is a zinc finger transcription factor widely expressed in the urogenital system. Human mutations of WT1 lead to pediatric nephroblastoma as well as frequent differences of sex development (DSDs). Previous studies have suggested that WT1 acts as an activator for Amhr2, a necessary component of typical male differentiation. We used the mouse as a model to investigate the role of WT1 in sex development, where we deleted Wt1 in the Müllerian duct (MD) mesenchyme using a novel conditional null reporter allele, Wt1 flox-RFP. This allele utilizes the Cre-lox system to delete exons 8 and 9 of Wt1 …

Lee, Alzheimer’S Biomarker Consortium – Down Syndrome (Abc-Ds)

Neurology Faculty Publications

Background Individuals with Down syndrome (DS) are at high risk of early-onset Alzheimer’s disease (AD); yet, some 20 percent do not develop any signs of dementia until after 65 years or in their lifetime. Mosaicism could contribute to this phenotypic variation, where some disomic cells could lead to lower levels of gene products from chromosome 21.

Methods We examined longitudinal neuropsychological and biomarker data from two large studies of DS: the Alzheimer Biomarker Consortium–Down syndrome study (ABC-DS) (n = 357); and a legacy study (n = 468). We assessed mosaicism using karyotyping or GWAS data. Participants had data on plasma …

Functional Analysis Of The Zebrafish Orthologs Of Host Cell Factor 1 Gene, David Paz

Open Access Theses & Dissertations

Host Cell Factor C1 (HCFC1) is a transcriptional co-activator factor that regulates the expression of over 5000 different downstream target genes in human cells. Missense mutations in the HCFC1 gene cause methylmalonic acidemia homocysteinemia cblX type (cblX). cblX, a multiple congenital anomaly syndrome (MCA) characterized by abnormal brain development, craniofacial abnormalities, metabolic deficits, and intractable epilepsy. Published studies suggest that HCFC1 regulates neural precursor proliferation, number, and differentiation. However, these results were derived from studies that were performed with nonsense alleles or transient knockdown approaches. Although these results demonstrate the importance of HCFC1 in brain development, they do not replicate …

Independent Evolution Of Oleate Hydratase Clades In Bacillales Reflects Molecular Convergence, Robert J. Neff, Priscilla C. Lages, Shannon K. Donworth, James D. Brien, Christopher D. Radka

Markey Cancer Center Faculty Publications

Oleate hydratase (OhyA), a flavoenzyme that catalyzes the hydration of unsaturated fatty acids, has been identified in various Bacillales organisms, including those in the Listeria, Lysinibacillus, Paenibacillus, and Staphylococcus genera. In this study, we combine structural biology with molecular and phylogenetic analyses to investigate the evolutionary dynamics of the OhyA protein family within the Bacillales order. Our evolutionary analysis reveals two distinct OhyA clades (clade I and clade II) within Bacillales that, while sharing catalytic function, exhibit significant genomic and structural differences. Our findings suggest that these OhyA clades originated from independent evolutionary processes through convergent evolution rather than gene …

Exercise intolerance, a hallmark of heart failure with preserved ejection fraction (HFpEF) exacerbated by obesity, involves unclear mechanisms related to skeletal muscle metabolism. In a “2-hit” model of HFpEF, we investigated the ability of exercise therapy (voluntary wheel running) to reverse skeletal muscle dysfunction and exercise intolerance. Using state-of-the-art metabolic cages and a multiomic approach, we demonstrate exercise can rescue dysfunctional skeletal muscle lipid and branched-chain amino acid oxidation and restore exercise capacity in mice with cardiometabolic HFpEF. These results underscore the importance of skeletal muscle metabolism to improve exercise intolerance in HFpEF.

A Pan-Cancer Single-Cell Analysis Of Intratumoral Copy Number Diversity And Evolution, Hanghui Ye

Dissertations and Theses (Open Access)

Aneuploidy is a hallmark of human cancers, with many copy number aberrations (CNAs) being associated with disease progression. Previous studies have revealed extensive inter-patient heterogeneity (IPH) in copy number profiles. However, the extent of intratumoral heterogeneity (ITH) and its evolutionary dynamics remain poorly understood.

To address these gaps, we developed Acoustic Cell Tagmentation (ACT), an advanced single-cell single-molecule DNA sequencing (scDNA-seq) technology, to resolve the copy number substructure of human tumors and investigate the evolution of aneuploidy. Applying ACT to eight triple-negative breast cancer (TNBC) patients to profile 9,765 aneuploid tumor cells, we discovered that following initial punctuated copy number …

Investigating The Rare Aneuploid Cells In Normal Breast And Therapeutic Resistance In Triple Negative Breast Cancer Using Single Cell Genomics, Yiyun Lin

Dissertations and Theses (Open Access)

Aneuploid epithelial cells are common in breast cancer, however their presence in normal breast tissues is not well understood. To address this question, we applied single cell DNA sequencing to profile copy number alterations (CNAs) in 83,206 epithelial cells from breast tissues of 49 healthy women and single cell DNA&ATAC co-assays to 19 women. Our data shows that all women harbored rare aneuploid epithelial cells (median 3.19%) that increased with age. Many aneuploid epithelial cells (median 82.22%) in normal breast tissues underwent clonal expansions and harbored CNAs reminiscent of invasive breast cancers (gains of 1q, losses of 10q, 16q and …

Assessing The Temporal Role Of Mir-200 Loss In Murine Models Of Nsclc, Jared Fradette

Dissertations and Theses (Open Access)

Lung cancer is the leading cause of cancer related deaths in the United States, with non-small cell lung cancer (NSCLC) making up a majority of new diagnoses. Metastasis is the big killer in NSCLC and is driven by epithelial-mesenchymal transition (EMT) and immune evasion. The microRNA 200 family is a master regulator of EMT and is implicated in immune regulation. In this study we have developed a novel genetically engineered mouse model (GEMM) and derived primary cell lines from them to explore the role of microRNA-200 in early EMT and immune changes. Our model combines conditional activation of Kras^{G12D …}

Bap1: Genotype-Phenotype Correlation, Variant Classification, And Treatment Efficacy, Elizabeth Hobbs

All Dissertations

BRCA1-associated protein 1 (BAP1) is a tumor suppressor gene located on chromosome 3p21.3 and encodes a deubiquitinase enzyme (DUB) involved in DNA repair, cell cycle and metabolism, and apoptosis. BAP1 pathogenic germline variants are primarily associated with a familial cancer syndrome, Tumor Predisposition Syndrome 1 (TPDS1), but new missense variants have been linked to a neurodevelopmental disorder known as Kury-Isidor Syndrome (KURIS). Patients with TPDS1 variants have an increased risk for developing cancers, such as uveal and cutaneous melanomas, mesothelioma, and renal cell carcinoma, at an earlier age with lower thresholds for environmental exposures, mainly UV rays and asbestos, compared …

Characterizing Mechanisms Of Dna Repair And Genome Stability, Joshua Turner

All Dissertations

Every day our cells are bombarded with DNA lesions that threaten the stability of our genome. To help maintain genomic integrity our cells evolved to have a network of enzymes dedicated to repairing DNA lesions. Upon encountering a site of DNA damage, a cell recruits enzymes that remodel the stalled replication fork by reannealing the newly synthesized DNA together known as fork regression. Loss of fork regression activity has been shown to promote replication stress resistance after induced DNA damage. In this thesis, I discuss the role F-Box Helicase 1 (FBH1) plays in fork regression and how FBH1 promotes the …

Advancing Substance Use Disorder Treatment Using Genomics And Metabolomics, Lindsey Contella

All Dissertations

Advancing our understanding of genetic, metabolic, and environmental factors in substance use disorder (SUD) could lead to more effective therapies. In 2022, 16.5% of the U.S. population was diagnosed with SUD, yet current treatments lack efficacy for all patients, making a precision medicine approach crucial. This dissertation explores SUD's relationship with tryptophan (TRP) metabolism through the kynurenine pathway (KP) as a potential therapeutic target. Chapter I reviews current knowledge on SUD and KP. Chapter II identifies how SUD alters KP metabolite concentrations, identifying a reduced concentration of the neuroprotective metabolite, kynurenic acid (KA) and elevated concentrations of the neurotoxic metabolite, …

Phelan-McDermid syndrome (PMS) is characterized by genetic and phenotypic variability with varying levels of developmental delay, intellectual disability (ID), autism spectrum disorder (ASD), speech delay, minor dysmorphic features, and behavioral issues. Genetic causes of PMS involve deletions in the 22q13.3 region or pathogenic/likely pathogenic variants in SHANK3. Due to the significant heterogeneity and complexities seen in individuals with PMS, there are numerous challenges surrounding research, accurate diagnoses, assessments, and the creation of treatments. Behavioral issues are present in the majority of individuals with PMS, including lower levels of adaptive behavioral skills needed for daily functioning, disruptive behaviors, restricted and …

Drosophila Model Of Cocaine Use Disorder, Jeffrey Hatfield

All Dissertations

Cocaine use disorder (CUD) is a major public health challenge. While the primary mechanism of action of cocaine has been well characterized, and family studies have identified a strong genetic component, the specific genetic factors that influence susceptibility to development of CUD remain poorly understood. Genetic studies of cocaine use disorder are difficult in humans, but can be readily performed in Drosophila, where environment, genetic background, and cocaine exposure can be controlled. Drosophila exhibit behavioral and transcriptomic responses to cocaine, which binds to the dopamine transporter in fruit flies as it does in humans. Here, we use Drosophila to …

Size Matters: The Characterization Of Telomere Function In Germ Cell Development In Danio Rerio, Jessica Macneil

Graduate Doctoral Dissertations

Infertility is a growing problem worldwide. According to the WHO, 48 million couples across the globe suffer from infertility and many couples turn to Assisted Reproductive Technology (ART) to become pregnant. One readout of gamete quality and successful ART is telomere integrity because telomeres are necessary for chromosome movements during meiosis so that the segregation of chromosomes happens correctly. Telomeres are well known for their role in aging; however, they play an important and understudied role during meiosis. In meiosis, telomeres attach to the nuclear envelope (NE) via a protein chain spanning the NE that interacts with cytoplasmic motor proteins, …

Splicing factors are affected by recurrent somatic mutations and copy number variations in several types of haematologic and solid malignancies, which is often seen as prima facie evidence that splicing aberrations can drive cancer initiation and progression. However, numerous spliceosome components also 'moonlight' in DNA repair and other cellular processes, making their precise role in cancer difficult to pinpoint. Still, few would deny that dysregulated mRNA splicing is a pervasive feature of most cancers. Correctly interpreting these molecular fingerprints can reveal novel tumour vulnerabilities and untapped therapeutic opportunities. Yet multiple technological challenges, lingering misconceptions, and outstanding questions hinder clinical translation. …

Williams syndrome (WS) is a rare multisystemic disorder caused by recurrent microdeletions on 7q11.23, characterized by intellectual disability, distinctive craniofacial and dental features, and cardiovascular problems. Previous studies have explored the roles of individual genes within these microdeletions in contributing to WS phenotypes. Here, we report five patients with WS with 1.4 Mb-1.5 Mb microdeletions that include RFC2, as well as one patient with a 167-kb microdeletion involving RFC2 and six patients with intragenic variants within RFC2. To investigate the potential involvement of RFC2 in WS pathogenicity, we generate a rfc2 knockout (KO) zebrafish using CRISPR-Cas9 technology. Additionally, we generate …

BACKGROUND: Genome-wide association studies (GWAS) have identified more than 200 breast cancer risk-associated genetic loci, yet the causal genes and biological mechanisms for most loci remain elusive. Proteins, as final gene products, are pivotal in cellular function. In this study, we conducted a proteome-wide association study (PWAS) to identify proteins in breast tissue related to breast cancer risk.

METHODS: We profiled the proteome in fresh frozen breast tissue samples from 120 cancer-free European-ancestry women from the Susan G. Komen Tissue Bank (KTB). Protein expression levels were log2-transformed then normalized via quantile and inverse-rank transformations. GWAS data were also generated for …

Alzheimer's disease is one of at least 26 diseases characterized by tau-positive accumulation in neurons, glia or both. However, it is still unclear what modifications cause soluble tau to transform into insoluble aggregates. We previously performed genetic screens that identified tyrosine kinase 2 (TYK2) as a candidate regulator of tau levels. Here we verified this finding and found that TYK2 phosphorylates tau at tyrosine 29 (Tyr29) leading to its stabilization and promoting its aggregation in human cells. We discovered that TYK2-mediated Tyr29 phosphorylation interferes with autophagic clearance of tau. We also show that TYK2-mediated phosphorylation of Tyr29 facilitates pathological tau …

The Anti-Diabetic Drug Metformin Disrupts Feeding And Sleeping Behaviors In Drosophila Melanogaster, Lucas Fitzgerald

The Cardinal Edge

Dimethylbiguanide, also known as metformin, is the single most prescribed oral treatment for non-insulin dependent diabetes mellitus, or type 2 diabetes, in western countries. The primary mechanism of action that metformin acts through is the activation of AMP kinase, an important regulator of energy homeostasis. While the anti-diabetic effects of metformin are well documented, its effects on feeding and sleeping behaviors are not well characterized. Using the model organism Drosophila melanogaster, the mean daily quantity of food consumed was measured and compared between groups treated with several dosages of metformin. Feeding interactions such as meal frequency and length were …

Glial-Specific Genes Are Strongly Associated With Alzheimer's Disease By Gene-Based Polygenic Risk Score Analysis, Jennifer Zheng, Faria Tavacoli, Tyrell Pratt, Alice Lee, Tingwei Liu, Jingchun Chen

Undergraduate Research Symposium Posters

Methods: Gene-based PRSs were constructed in AD cases and controls within each gene of the glial cells, according to the GWAS summary statistics of European ancestry. In detail, gene-based PRSs were first calculated for each glial cell type-specific gene for AD cases and controls in the discovery dataset (ADc1234ADA) using PRSet software. A meta-analysis with a fixed model was performed when the signal in both datasets was in the same direction. Bonferroni corrections for multiple testing (at α = .05) were used to determine significance within each of the three glial groups. Forest plots were used to visualize the results …

BACKGROUND: As previously published, the MMPOWER-3 clinical trial did not demonstrate a significant benefit of elamipretide treatment in a genotypically diverse population of adults with primary mitochondrial myopathy (PMM). However, the prespecified subgroup of subjects with disease-causing nuclear DNA (nDNA) pathogenic variants receiving elamipretide experienced an improvement in the six-minute walk test (6MWT), while the cohort of subjects with mitochondrial DNA (mtDNA) pathogenic variants showed no difference versus placebo. These published findings prompted additional genotype-specific post hoc analyses of the MMPOWER-3 trial. Here, we present these analyses to further investigate the findings and to seek trends and commonalities among those …
