Cazyme Gene Cluster Diversity In Human Gut Microbiome, Yi Xing

Department of Food Science and Technology: Dissertations, Theses, and Student Research

In gut microbiome research, carbohydrate-active enzyme gene clusters (CGCs) have emerged as key functional units for understanding microbial glycan degradation. Unlike taxonomic or broad pathway annotations, CGCs offer gene-cluster-level resolution and capture substrate-specific microbial functions. However, their diversity and distribution in relation to host metabolic phenotypes, such as obesity, remain poorly characterized. This study tests the hypothesis that the composition and abundance of fiber-targeting CGCs vary between obese and healthy human gut microbiomes, reflecting distinct microbial carbohydrate utilization strategies. To examine this, we constructed a high-quality reference CGC dataset comprising 94,019 clusters from the Unified Human Gastrointestinal Genome and profiled …

Ifi16 Mediates Deacetylation Of Kshv Chromatin Via Interaction With Nurd And Sin3a Co-Repressor Complexes, Anandita Ghosh, Bala Chandran, Arunava Roy

School of Medicine Faculty Publications

IFI16 is a well-characterized nuclear innate immune DNA sensor that detects foreign dsDNA, including herpesviral genomes, to activate the inflammasome and interferon pathways. Beyond immune signaling, IFI16 also functions as an antiviral restriction factor, promoting the silencing of invading viral genes through transcriptional and epigenetic mechanisms. We recently demonstrated another role of IFI16, in which it interacts with and recruits the class I histone deacetylases, HDAC1 and 2, to the KSHV latency protein LANA, modulating its acetylation and function. In this study, we asked whether these IFI16-HDAC1/2 interactions contribute to broader epigenetic regulation of the KSHV chromatin. Our findings reveal …

Exploring Muslim American Attitudes Toward Genetic Testing: Perceptions, Barriers, And Ethical Considerations, Hannah Mahmoud

University Honors Theses

This thesis explores perceptions and attitudes toward genetic testing within the Muslim American community, a group often underrepresented in genomic research and public health discourse. Using a community-distributed digital survey, data was collected from 50 self-identified Muslim Americans on their familiarity with genetic testing, reproductive and ethical considerations, and the influence of religious factors. While only 18% had undergone genetic testing themselves, many were familiar through family or friends, and most expressed cautious interest—especially when results could influence future family planning. Education level, age, and religious values shaped both comfort and understanding.

A key theme was the desire for culturally …

Topodino: Self-Supervised Topological Representation Learning For Neuronal Morphologies, Yasser Binbisher

Master's Theses

Neuronal cell types are categorized by transcriptomic identity, yet their morphological heterogeneity defies this classification. In response, researchers have adopted unsupervised graph representation learning as a tool to reveal morphological variation within single-class transcriptomic types. However, the complex geometry of neuronal morphology—especially long axons and dense dendrites—challenges graph neural networks, which struggle with message propagation across extended structures. To mitigate this, current approaches enforce sub-sampling on neuronal graphs and omit axons entirely, sacrificing critical biological features for computational efficiency. To overcome this trade-off, this thesis introduces TopoDINO, a self-supervised, topology-aware representation learning model designed to preserve the full hierarchical organization …

Genetic Analysis Of Psychosis Biotypes: Shared Ancestry-Adjusted Polygenic Risk And Unique Genomic Associations, Cuihua Xia, Ney Alliey Rodriguez, Carol A. Tamminga, Matcheri S. Keshavan, Godfrey Pearlson

School of Medicine Publications

The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) created psychosis Biotypes based on neurobiological measurements in a multi-ancestry sample. These Biotypes cut across DSM diagnoses of schizophrenia, schizoaffective disorder, and bipolar disorder with psychosis. Two recently developed post hoc ancestry adjustment methods of Polygenic Risk Scores (PRSs) generate Ancestry-Adjusted PRSs (AAPRSs), which allow for PRS analysis of multi-ancestry samples. Applied to schizophrenia PRS, we found the Khera AAPRS method to show superior portability and comparable prediction accuracy as compared with the Ge method. The three Biotypes of psychosis disorders had similar AAPRSs across ancestries. In genomic analysis of Biotypes, 12 genes, …

A Scan Of Pleiotropic Immune Mediated Disease Genes Identifies Novel Determinants Of Baseline Fviii Inhibitor Status In Hemophilia A, Marcio Almeida, Vincent P. Diego, Kevin R. Viel, Bernadette W. Luu, Eron G. Manusov, Juan M. Peralta, Satish Kumar, Sarah Williams-Blangero, John Blangero, Tom Howard

School of Medicine Publications

Hemophilia-A (HA) is the X-linked bleeding disorder caused by heterogeneous factor (F)VIII gene (F8)-mutations and deficiencies in plasma-FVIII-activity that prevent intrinsic-pathway mediated coagulation-amplification. Severe-HA patients (HAPs) require life-long infusions of therapeutic-FVIII-proteins (tFVIIIs) but ~30% develop neutralizing-tFVIII-antibodies called “FVIII-inhibitors (FEIs)”. We investigated the genetics underlying the variable risk of FEI-development in 450 North American HAPs (206 and 244 respectively self-reporting black-African- or white-European-ancestry) by analyzing the genotypes of single-nucleotide-variations (SNVs) in candidate immune-mediated-disease (IMD)-genes using a binary linear-mixed model of genetic association with baseline-FEI-status, the dependent variable, while simultaneously accounting for their genetic relationships and heterogeneous-F8-mutations to …

Musculoskeletal tumors present a diagnostic challenge due to their rarity, histological diversity, and overlapping imaging features. Accurate characterization is essential for effective treatment planning and prognosis, yet current diagnostic workflows rely heavily on invasive biopsy and subjective radiologic interpretation. This review explores the evolving role of radiogenomics and machine learning in improving diagnostic accuracy for bone and soft tissue tumors. We examine integrating quantitative imaging features from MRI, CT, and PET with genomic and transcriptomic data to enable non-invasive tumor profiling. AI-powered platforms employing convolutional neural networks (CNNs) and radiomic texture analysis show promising results in tumor grading, subtype differentiation …

The Role Of G6pd Variants And 3d Genomic Structure In The Development Of Pulmonary Hypertension, Christina M. Signoretti Ph.D.

NYMC Student Theses and Dissertations

Pulmonary hypertension is an under-recognized global health epidemic which is estimated to affect 1% of the population. It is associated with sustained mean pulmonary artery pressure greater than 20 mmHg, pulmonary artery remodeling, smooth muscle and endothelial cell proliferation and subsequent increased right ventricle hypertrophy due to increased afterload. Glucose-6-phosphate dehydrogenase (G6PD) is one of the key enzymes in the pentose phosphate pathway and has been previously linked to the development of pulmonary hypertension. G6PD deficiency is the most common human enzymopathy which affects approximately 400 million people worldwide and is a result of agricultural and epidemiological evolution in different …

Endophenotype-Informed Association Analyses For Liver Fat Accumulation And Metabolic Dysfunction In The Fels Longitudinal Study, Ariana L. Garza, John Blangero, Miryoung Lee, Cici X. Bauer, Stefan A. Czerwinski, Audrey Choh

School of Medicine Publications

The identification of causal genomic regions for liver fat accumulation in the context of metabolic dysfunction remains a challenging goal. This study aimed to identify potential endophenotypes for liver fat content and employ them in bivariate linkage searches for pleiotropic genetic regions where targeted association analysis is more likely to reveal significant variants. Multiple metabolic risk and adiposity distribution traits were assessed using the endophenotype ranking value. The top-ranked endophenotypes were then used in a bivariate linkage analysis, paired with liver fat content. Quantitative trait loci (QTLs) identified as significant or suggestive were targeted for measured genotype association analyses. The …

Investigating The Influence Of Environmental Stressors To Exopolysaccharide Production In Soil Cyanobacteria: Genomic And Physiological Perspectives, Benjy Sedano-Herrera

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cyanobacteria are photosynthetic microbes with essential roles in Earth’s ecosystems. The secretion of long–chain polysaccharides, known as exopolysaccharides (EPS), is a key trait facilitating cyanobacterial adaptation to diverse ecosystems. Genomics studies have shown that aquatic cyanobacteria harbor multiple gene copies encoding EPS export proteins, likely conferring a selective advantage in lakes or oceans. In addition, physiological experiments showed that nutrient limitation in aquatic habitats influences EPS production, affecting cyanobacterial fitness. However, whether terrestrial cyanobacteria also harbor multiple EPS-related genes and how nutrient limitation impacts their EPS production is not well understood.In the first chapter of my thesis, we investigated the …

Mesoderm-Specific Transcript Has A Role In The Systemic Regulation Of Obesity, Maria J. Orellana Rosales

Thinking Matters Symposium

Mesoderm specific transcript (Mest) expression in white adipose tissue (WAT) is variable in genetically identical mice. Previous studies have shown a connection between Mest high expression and propensity for fat mass expansion. WAT and liver crosstalk has been well documented with hormone-like peptides signaling and regulating important metabolic pathways. The aim of this study is to investigate the correlation between these circulating factors and Mest expression in mice after exposure to a high fat diet (HFD). A group of 120 C57B6/J mice, males and females, were exposed to a HFD (Western Diet, 40 kcal% fat) for 4 weeks (8-12 weeks …

Sirt6 Deficiency Promotes Senescence And Age-Associated Intervertebral Disc Degeneration In Mice, Pranay Ramteke, Bahiyah Watson, Mallory Toci, Victoria Tran, Shira N Johnston, Maria Tsingas, Ruteja Barve, Ramkrishna Mitra, Richard Loeser, John Collins, Makarand Risbud

Department of Orthopaedic Surgery Faculty Papers

Intervertebral disc degeneration is a major risk factor contributing to chronic low back and neck pain. While the etiological factors for disc degeneration vary, age is still one of the most important risk factors. Recent studies have shown the promising role of SIRT6 in mammalian aging and skeletal tissue health, however its role in the intervertebral disc health remains unexplored. We investigated the contribution of SIRT6 to disc health by studying the age-dependent spinal phenotype of mice with conditional deletion of Sirt6 in the disc (Acan^CreERT2; Sirt6^fl/fl). Histological studies showed a degenerative phenotype in knockout mice …

Lifespan Reference Curves For Harmonizing Multi-Site Regional Brain White Matter Metrics From Diffusion Mri, Alyssa H. Zhu, Talia M. Nir, Shayan Javid, Julio E. Villalón-Reina, Amanda L. Rodrigue, Lachlan T. Strike, Greig I. De Zubicaray, Katie L. Mcmahon, Margaret J. Wright, John Blangero

School of Medicine Publications

Age-related white matter (WM) microstructure maturation and decline occur throughout the human lifespan, complementing the process of gray matter development and degeneration. Here, we create normative lifespan reference curves for global and regional WM microstructure by harmonizing diffusion MRI (dMRI)-derived data from ten public datasets (N = 40,898 subjects; age: 3–95 years; 47.6% male). We tested three harmonization methods on regional diffusion tensor imaging (DTI) based fractional anisotropy (FA), a metric of WM microstructure, extracted using the ENIGMA-DTI pipeline. ComBat-GAM harmonization provided multi-study trajectories most consistent with known WM maturation peaks. Lifespan FA reference curves were validated with test-retest data …

Examining Loss Of Imprint In F1 Hybrid Female Mice Due To X Chromosome Epimutation And The Implications For Autism, Arianna H. Roach

Honors Scholar Theses

Sex biases are prevalent among various neurodevelopmental disorders, with males experiencing them at higher frequencies or severities than females. This male bias is poorly understood, and our lab aims to elucidate this mechanism using our model of transgenerational epigenetic inheritance. Our lab identified the cluster of genes Xlr3b/4b/4c on the X chromosome that are imprinted in the female brain. Preliminary studies suggest that Xlr3 acts as a mediator molecule in our model. Xlr3 knockdown male mice exhibited significant meiocyte loss that can be attributed to Meiotic Sex Chromosome Inactivation. Their female offspring also displayed loss of imprinting of Xlr3 and …

Pseudomonas Aeruginosa Exoy Enzymatic Activity Inhibits Exos-Induced Caspase-3/7 Activation But Not Cytotoxicity In Pmvecs, Connor Holm

Poster Presentations

Pseudomonas aeruginosa (P. aer.) is the most common cause of ventilator associated pneumonia (VAP) in ICU patients. Different combinations of exoenzymes (S, T, Y, and U) are found in P. aer. strains. ExoY is most often associated with VAP in ICU patients. ExoY infection of pulmonary microvascular endothelial cells (PMVECs) induces cell rounding but does not activate intracellular caspase-3/7 or cause cell death. ExoS and ExoT infection of epithelial cells leads to caspase-3/7 dependent cell death. Previous studies using epithelial cells show that ExoY alleviates the cytotoxic effects of ExoS and ExoT. Here, we sought to determine whether ExoY inhibits …

A Review On Treatment, Prevention, And Research Of Worldwide Parasitic Disease: Toxoplasmosis, Hannah Skinner

All Theses

Toxoplasmosis is a worldwide, yet often overlooked, parasitic disease caused by the protozoan parasite, Toxoplasma gondii. The parasite is capable of infecting humans and almost all warm-blooded vertebrates. Over a million people are infected in the United States with toxoplasmosis each year. Most infections are asymptomatic but severe cases can lead to vision impairment, neurological disorders, and congenital birth defects. T. gondii is transmitted through undercooked meat, infected feline feces, or contaminated water and soil. The burden of T. gondii infection is most notable in livestock, felines, and immunocompromised humans. Despite being a widespread disease, toxoplasmosis is neglected in …

Role Of Evolutionarily Conserved G4 Structures In Enhancer-Promotor Interactions, Shahem Alqudah

Honors Theses

Gene regulation is governed by complex networks of interactions between enhancers and promoters, regions of the genome that are typically distant from one another yet functionally linked through chromatin looping. Recent research has revealed the significant role of Gquadruplexes (G4s) in facilitating these interactions. This thesis explores the role of long Gquadruplex regions (LG4s) in enhancer–promoter communication, proposing that these regions mediate physical interactions between enhancers and their target promoters through direct G4:G4 interactions. Using a chromatin conformation capture (EQuIP-seq), electrophoretic mobility shift assays (EMSA), and luciferase reporter assays, the study demonstrates that LG4s may drive gene expression by promoting …

Implications Of Type Iv Pilus Retraction For Dna Uptake By Acinetobacter Baumannii, Yafan Yu

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Horizontal gene transfer (HGT) via natural competence allows bacteria to incorporate extracellular DNA (eDNA) into their genomes, facilitating genetic diversity and adaptation. In Acinetobacter species, natural competence depends on DNA binding and uptake mediated by type IV pili (T4P). T4P are dynamic extracellular filaments composed primarily of the major pilin subunit PilA, along with a few minor subunits. T4P drive a range of cellular functions including twitching motility, biofilm formation, and DNA uptake, with some functions dependent on pilus retraction and others not. However, how Acinetobacter T4P bind DNA and how T4P/eDNA interactions impact biofilm formation remain unclear. Here, I …

Hypoxia Induced Ribosomal Rna Fragmentation Mediated By Rnase L, Vanessa Kristina Pizutelli, Dimitri G Pestov

Rowan-Virtua Research Day

Ischemic injury contributes to a range of global pathologies. Ischemia/Reperfusion Injury (IRI) is a paradoxical phenomenon that involves an initial restriction of blood flow followed by a sudden restoration of perfusion. This type of injury takes place in conditions such as myocardial infarction, acute kidney disease, and ischemic stroke and often leads to cellular death. Additionally, IRI exacerbates post-surgical outcomes and plays a role in graft dysfunction and transplant rejection. Despite efforts to develop therapies targeting known IRI pathways, clinical trials have largely been unsuccessful, underscoring the need for alternative mechanisms and biomarkers associated with IRI-induced apoptosis. Reactive oxygen species …

The relative failure of immune checkpoint inhibitors in pancreatic ductal adenocarcinoma (PDAC) despite having a dense, immunosuppressive tumor microenvironment highlights the need to target alternate/escape pathways. We have previously examined C–C chemokine receptor type 9 (CCR9) as a candidate immune checkpoint and developed a targeted, humanized monoclonal antibody (SRB2). Cytotoxicity of SRB2 was evaluated in vitro and in vivo. CCR9 expression on PDAC cells/tissues, immune components of patient-derived organoids (PDOs), and antibody-dependent cell-mediated cytotoxicity were examined. In PANC-1 and MIA PaCa-2 cell lines, we demonstrated highest CCR9 expression; however, no direct cytotoxic effect was observed with SRB2 treatment. In PANC-1 …

Elucidating The Multi-Omics Of Early-Onset Colorectal Cancer, Jumanah Alshenaifi

Dissertations and Theses (Open Access)

The incidence and mortality rates of sporadic early-onset colorectal cancer have increased in recent decades, but there is no clear etiological basis for this trend. EOCRC is commonly defined as colon and rectal cancers diagnosed before the age of 50 years. The rising incidence of EOCRC has made it the second most common cancer and the third leading cause of cancer death in this age group. The rising incidence of EOCRC is also documented internationally in more than 20 countries across different continents. Clinically, EOCRC has a distinct, more aggressive clinical profile than LOCRC. While approximately 15% of EOCRC cases …

The Influence Of Scientific, Genetic, And Health Literacy On Carrier Screening Decision-Making, Brenna D. Albracht

Dissertations and Theses (Open Access)

For those wishing to assess their reproductive risks and make informed decisions in their reproductive planning, carrier screening for autosomal recessive and X-linked conditions, as well as cell-free DNA (cfDNA) screening for aneuploidy, are recommended during pregnancy. Despite similarities in purpose, sample requirements, insurance coverage, and safety, a lower percentage of individuals elect carrier screening than cfDNA screening, suggesting there may be a disconnect in what patients perceive as valuable information for their pregnancy. Previous studies have attempted to explain the factors associated with carrier screening uptake or decline; however, no models have yet accounted for a patient’s literacy level …

Evaluating Triage To Genetic Counseling Using An Online Reproductive Genetics Module, Grace Ra

Dissertations and Theses (Open Access)

The American College of Obstetricians and Gynecologists recommends genetic screening for all pregnant women. As clinical recommendations broaden and demand for prenatal screening increases, obstetric practitioners report time constraints and lack of genetics knowledge as challenges to providing sufficient pretest education. These challenges in offering routine screening are further compounded by the inequities in access to genetic counseling and testing. Thus, alternative education and service delivery models have emerged to meet the demands for prenatal genetics education and help mitigate challenges surrounding access. At UTHealth Houston, an online triage and education module, the Prenatal Genetics Education Program (PGEP), was created …
