Dissecting Macrophage Metabolism In Metabolic Liver Disease, Mandy Mei-Ying Chan

Arts & Sciences Graduate Student Theses and Dissertations

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common cause of chronic liver disease around the globe; however, the mechanisms that lead to the progression of metabolic liver disease are poorly understood. Liver-resident macrophages, known as Kupffer cells (KCs), are the largest population of macrophage in the human body, playing a critical role in immune sensing and tissue homeostasis. In the context of MASLD, KCs undergo cell death through an unclear mechanism, and monocytes enter the liver where they differentiate into macrophages. Next-generation sequencing and spatial-omics studies have revealed significant, heterogeneity in the recruited macrophage populations in both human …

Computational And In Vitro Investigation Of P. Crocatum Bioactive Compounds As Pancreatic Lipase Inhibitors, Gusnia Meilin Gholam, Dimas Andrianto, Dewi Anggraini Septaningsih, Mega Safithri

Karbala International Journal of Modern Science

Obesity, a prevalent metabolic disorder characterized by excessive fat accumulation, can severely affect overall health if left untreated. This study investigated the potential of a 70% ethanol extract from Piper crocatum (red betel) leaves as an in vitro inhibitor of pancreatic lipase (PL), supported by computational analyses to identify alternative compounds to orlistat. The phytochemical profile was characterized using LC-MS/MS, revealing alkaloids and terpenoids with contents of 1.1 ± 0.01 mg CE/g and 3.14 ± 0.3 mg UAE/g, respectively. The extract exhibited 49 ± 9.1% inhibition of PL activity. Molecular docking identified three promising compounds: calanolide A (10.43 kcal/mol), myricanone …

Baseline Testosterone Levels Peak During The Inactive Period In Male Degus (Octodon Degus), Yuta Sato , '26, Tate M. S. Garcia , '26, Josephine S. Low , '27, Carolyn M. Bauer

Biology Faculty Works

The steroid hormone testosterone is important for stimulating male reproductive processes including territory acquisition, mating displays, and spermatogenesis. When examining the relative effects of testosterone on reproductive processes, it is most reasonable to focus on peak baseline testosterone levels, especially for reproductive processes that may occur during specific times of day, such as mating and spermatogenesis. However, some studies have not found consistent positive relationships between circulating testosterone levels and reproductive variables. These nonsignificant relationships could be driven by methodology, as most studies in wild, free-living animals collect blood samples during an animals' active period, yet many species show peak …

In Silico Prediction Of Cytotoxic T-Cell Epitopes From Helicobacter Pylori Virulence Factors Using An Immunoinformatics Approach, Demy Valerie Chacon, Kiana Alika Co, Daphne Noreen Enriquez, Aubrey Love Labarda, Reanne Eden Manongsong, Edward Kevin B. Bragais

Biology Faculty Publications

Background: Helicobacter pylori infects approximately half of the global population, leading to gastric and duodenal ulcers. Despite the availability of antibiotics, challenges such as patient reluctance, high treatment costs, and antibiotic resistance limit their effectiveness, making vaccination a promising alternative. This study used immunoinformatics to identify candidate epitopes for a multiepitope vaccine construct against H. pylori.

Material and methods: The protein variability server was utilized for conservation analysis. The epitopes were screened for antigenicity, allergenicity, toxicity, cross-reactivity, and population coverage. Selected epitopes were docked with their corresponding human leukocyte antigen (HLA) alleles, and thermodynamic quantities were determined. Five virulence …

Assessing The Ecological Drivers And Consequences Of Partial Migration In Hudson River Striped Bass Over Three Decades, Caitlin Egan Zimmer

Biology ETDs

Climate change and shifts in human land use have caused extensive impacts to the connectivity, structure, and resilience of aquatic populations. Partial migration (PM), where only some individuals from a population migrate while the rest remain resident, can mitigate population-level responses to environmental stressors. However, little is known of the underlying mechanisms promoting variation in migration and whether these shift over time. In the Hudson River Estuary, striped bass (Morone saxatilis) are known to exhibit anadromous PM behavior. Here, I measured carbon isotopes (δ¹³C) of essential amino acids in striped bass scales to determine variation in …

Plant Reproductive Strategies Shift In Response To Restoration Using Beaver Dam Analogs, Laurel F. Martinez

Biology ETDs

As riparian communities become increasingly degraded, restoration treatments are being implemented in streams to recover ecosystem functions. In the Jemez Mountains, beaver dam analogs (BDAs) are used to restore degraded streams by connecting the floodplain and increasing the extent of anoxic soil conditions. These environmental disturbances are expected to alter how riparian plants recruit, particularly their allocation to seed-based and vegetative regeneration strategies. We investigated whether BDAs and associated changes in soil water filled pore space (WFPS) affected riparian plant recruitment. We investigated the number of flowering stems as a proxy for seed-based regeneration and rhizome length and mass as …

Ecoimmunology Of Dirty Physella Acuta Snails, Kevin Arthur Mcquirk

Biology ETDs

Research on Physella acuta, an invasive freshwater snail, reveals insights into its parasitology, fitness, and molecular biology. Morphological and molecular analyses revealed two distinct mitogenomic lineages, local (B) and invasive (A) strains of native P. acuta, both having comparable trematode infection rates, suggesting that the low infection rates observed from A in invaded regions result from "enemy release" rather than immune incompatibility. Fitness assessments showed that while lineages A and B performed similarly under laboratory conditions, rewilding experiments revealed significantly higher fitness in lineage A. Transcriptomic profiling supported these differences, with A snails showing greater immune-related gene expression and …

Spatial Ecology And Habitat Selection Of Eastern Pinesnakes: Case Study On The Importance Of Scale In Conservation Biology, Matthew Grisnik, Alan Jones, Rachel Brubaker, Andrew M. Grosse, Scott L. Parker

Biology

Species are in decline world-wide, driven by multiple factors including habitat fragmentation. Understanding the habitat selection processes of species in these fragmented landscapes has become a focus of ecological studies and is a major component of conservation plan development. However, understanding how landscape level processes influence patterns of habitat selection is often ignored. Here we assessed the influence of landscape level processes in the habitat selection of Eastern Pinesnakes, a species in decline, within a protected area in South Carolina, USA. Over the course of a year, we tracked 8 Eastern Pinesnakes within a small protected area. Snakes exhibited seasonal …

Using Triple Oxygen Isotopes To Investigate Water Usage In Desert Ecosystems, Cloe V. Knutson

Earth and Planetary Sciences ETDs

In arid environments, maintaining water balance can be more critical for survival than obtaining food. As droughts intensify, understanding how animals manage body water is essential. Triple oxygen isotope analysis provides a novel way to trace water sources in animals, distinguishing contributions from free water, food-derived oxygen, and atmospheric O₂. We developed an equilibration method using CO₂–H₂O oxygen exchange and measured δ^’18O and Δ^’17O values via tunable infrared laser direct spectroscopy (TILDAS). Validated against traditional fluorination methods, this technique enables streamlined analysis of whole blood and plant samples. Applied to …

Immune Regulation In Fungal Airway Inflammation And Host Defense, Ruoning Wang

Biomedical Sciences ETDs

Asthma is a chronic inflammatory disease of the lungs characterized by complex pathophysiological mechanisms and diverse endotypes, primarily categorized as T helper type 2 cell (Th2)-high and Th2-low asthma. Despite significant advances in understanding asthma pathogenesis, the mechanisms governing the pulmonary immune system’s response to external challenges have not been fully understood. To address these gaps, this comprehensive project was designed to investigate the interplay between fungal infections and specific CD4⁺ T cell populations in asthma. Our findings suggest that fungal infections can contribute to neutrophilic asthma by promoting the migration of platelet-myeloid aggregates into the lungs. We also …

Organic acids, as natural metabolites, play crucial roles in human metabolism and health. Tumor Necrosis Factor (TNF), a pivotal mediator in immune regulation and inflammation, is a key therapeutic target. We evaluated ten organic acids as TNF modulators using in silico molecular docking, followed by detailed ADMET (Absorption, Distribution, Metabolism, Excretion, and Toxicity) profiling and molecular dynamics (MD) simulations for three lead candidates: gallic, aconitic, and crocetin acids. Their effects on TNF gene expression were then assessed in vivo using a mouse leukocyte model. The in silico results indicated that crocetin had the highest TNF binding affinity (−5.6 to −4.6 …

Despite the success of targeted inhibitors in cutaneous melanoma, therapeutic responses are limited by the aged tumor microenvironment and drug-tolerant residual cells. Given the similarities between drug tolerance and cellular dormancy, we studied the dormancy marker, nuclear receptor subfamily 2 group F member 1 (NR2F1), in response to BRAF-V600E inhibitors (BRAFi) plus MEK inhibitors (MEKi) in BRAF-mutant melanoma models. Transcriptomic analysis of melanoma patient samples treated with BRAFi + MEKi showed increased NR2F1. NR2F1 was highly expressed in the drug-tolerant invasive cell state of minimal residual disease in patient-derived and mouse-derived xenografts on BRAFi + MEKi. NR2F1 over-expression was sufficient …

Computer Science ETDs

The adaptive immune response is a complex defense mechanism that develops over time to recognize and eliminate pathogens with remarkable precision and durability. This dissertation investigates the dynamics, scaling, and efficiency of the adaptive immune response through a synthesis of computational modeling, mathematical analysis, and agent-based simulations. First, we analyze the topology of the lymphatic network and investigate the T cell search time to find the lymph node that is containing the matching dendritic cell. Second we show how the scaling of lymph node number and volume with body mass, leads to scale-invariant search times for T cells locating antigen-bearing …

Glucose Metabolism And Its Direct Action In Cancer And Immune Regulation: Opportunities And Challenges For Metabolic Targeting, Bo-Syong Pan, Che-Chia Hsu, Hsin-En Wu, Yuan-Ru Chen, Xiaobo Zhou, Shu-Chi Wang, Chia-Yang Li, Hui-Kuan Lin

Faculty, Staff and Student Publications

Glucose metabolism is a pivotal hub for cellular energy production and the generation of building blocks that support cell growth, survival, and differentiation. Cancer cells undergo metabolic reprogramming to sustain rapid proliferation, survive in harsh microenvironments, and resist therapies. Beyond producing energy and building blocks to meet cancer cell demands, glucose metabolism generates numerous metabolites that serve as signaling molecules, orchestrating signaling pathways and epigenetic modifications that regulate cancer cell phenotypes and immunity. In this review, we discuss how glucose, through its metabolism and direct actions, influences diverse biological processes driving cancer progression and therapeutic resistance, while also exploring metabolic …

Non-Mutated Human Tau Stimulates Alzheimer’S Disease-Relevant Neurodegeneration In A Microglia-Dependent Manner, Ethan R Roy, Qiang Wang, Kexin Huang, Sanming Li, Yuanyuan Fan, Estrella Escobar, Constance L Atkins, Shuning Huang, Juan J Herrera, Wenbo Li, Clare Pridans, Xiaobo Zhou, Cynthia Ju, Wei Cao

Faculty, Staff and Student Publications

The accumulation of abnormal, non-mutated tau protein is a key pathological hallmark of Alzheimer's disease (AD). Despite its strong association with disease progression, the mechanisms by which tau drives neurodegeneration in the brain remain poorly understood. Here, we selectively expressed non-mutated or mutated human microtubule-associated protein tau (hMAPT) in neurons across the mouse brain and observed neurodegeneration in the hippocampus, especially associated with non-mutated human tau. Single-nuclei RNA sequencing confirmed a selective loss of hippocampal excitatory neurons by the wild-type tau and revealed the upregulation of neurodegeneration-related pathways in the affected populations. The accumulation of phosphorylated tau was accompanied by …

Cocoa Polyphenols Alter The Fecal Microbiome Without Mitigating Colitis In Mice Fed Healthy Or Western Basal Diets, Eliza C. Stewart, Mohammed F. Almatani, Marcus Hayden, Giovanni Rompato, Jeremy Case, Samuel Rice, Korry J. Hintze, Abby D. Benninghoff

Animal, Dairy, and Veterinary Science Student Research

Background/Objectives: Chronic inflammation and Western-style diets elevate colorectal cancer (CRC) risk, particularly in individuals with colitis, a feature of inflammatory bowel disease (IBD). Diets rich in polyphenol-containing functional foods, such as cocoa, may reduce gut inflammation and modulate the gut microbiome. This study investigated the impact of cocoa polyphenol (CP) supplementation on inflammation and microbiome composition in mice with colitis, fed either a healthy or Western diet, before, during, and after the onset of disease. We hypothesized that CPs would attenuate inflammation and promote distinct shifts in the microbiome, especially in the context of a Western diet. Methods: …

The Nature Of Anthropogenically Driven River Drying: Spatiotemporal Causes And Consequences, Eliza Inez Gilbert

Biology ETDs

Streambed drying naturally occurs in over 60% of rivers and streams worldwide. Climate change and human regulation of surface and groundwater have increased drying in naturally intermittent systems and caused perennial systems to transition to intermittency, impacting water security, water quality, and biodiversity. To understand human-induced drying dynamics, we used 12 years of daily drying data along a 154-km regulated reach of the Rio Grande. We conceptualized river drying as a regime analogous to the natural flow regime paradigm and quantified drying magnitude, rate of change, and duration. Although linear models predicting drying magnitude and rate of change were uninterpretable, …

Spherical amorphous Se NPs were produced by irradiating a selenium target using a combination of bottom- and top-ablation protocols. After autoclaving, the amorphous Se NPs were converted into trigonal Se NPs. Se NPs were characterized by using Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Fourier Transform Infrared Spectroscopy (FTIR). The biological effects of Se NPs were quantitatively assessed through evaluations of cell viability and associated …

Distributional Records Of Blanding’S Turtles (Emydoidea Blandingii) In Nebraska, Sam Thede, Dan Fogell, Keith Geluso

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Blanding’s Turtle (Emydoidea blandingii) is a species of concern in North America as many populations have declined across its distribution. Environmental factors associated with alteration of natural ecosystems have played a role in declines leading to many isolated populations. Most populations exist in the Great Lakes region with a number of outlying populations, such as Nebraska. Understanding the current distribution of the species will facilitate regional management strategies to protect this species into the future. In Nebraska, Blanding’s Turtles were known from 23 counties prior to this study. Herein, we report on eight new county records, five (Blaine, …

Cultural Worldview And Rural Consumer Preferences For Genetically Modified Foods, Nathan P. Kemper

Agricultural Economics and Agribusiness Faculty Publications and Presentations

The consumer acceptance of genetically modified (GM) foods varies widely based on personal values and social context. This study investigates how cultural worldviews—measured through the Individualism–Communitarianism and Hierarchical–Egalitarianism dimensions—affect willingness to pay (WTP) for food labeling attributes related to GM content. We surveyed 932 U.S. primary grocery shoppers and conducted a discrete choice experiment (DCE) with poultry product options. Using a Mixed Logit model and supplemental cognitive data from Query Theory, we find that rural individualists are more accepting of GM-labeled products. At the same time, urban communitarians show a stronger preference for non-GM labels. These results offer insight into …

Medulloblastoma (MB) is the most malignant childhood brain cancer. Group 3 MB (G3 MB) subtype accounts for about 25% of MB and is associated with the worst outcomes. Herein, we report that more than half of G3 MB tumors express melanoma antigens (MAGEs), which are potential prognostic and therapeutic markers. MAGEs are cancer-testis antigens, aberrantly expressed in several adult cancers, and associated with poorer prognosis and therapy resistance; however, their role in pediatric cancers is mostly unknown. This study aimed to determine whether MAGEs are activated and important in pediatric MB. We obtained formalin-fixed paraffin-embedded tumor samples of 34 patients, …

Effects Of Mating System And Adaptedness On The Evolution Of Fitness And Mtdna Copy Number In Mitonuclear Mismatched C. Elegans, Zachary P. Dietz, Devshuvam Banerji, Jennifer A. Sullins, Brent W. Bever, Stephen F. Christy, Ulfar Bergthorsson, Vaishali Katju, Suzanne Estes

Biology Faculty Publications and Presentations

Metabolic functioning in nearly all eukaryotes relies on molecular machinery dual-encoded by mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) genomes. The two genomes have sustained an extraordinary degree of cooperation across evolutionary time, preserving the capacity for indispensable processes including oxidative phosphorylation and ATP production, which in turn influence many fitness-related traits. How this cooperation is maintained when one member of the pair is debilitated by deleterious mutation is poorly understood, as is the influence of mutation location (mtDNA or nDNA), mating system, or the potentially compensatory effects of mtDNA copy number changes on the process. We asked whether and …

The differentiation and suppressive functions of regulatory CD4 T cells (Tregs) are supported by a broad array of metabolic changes, providing potential therapeutic targets for immune modulation. In this study, we focused on the regulatory role of glycolytic enzymes in Tregs and identified phosphoglycerate mutase (PGAM) as being differentially overexpressed in Tregs and associated with a highly suppressive phenotype. Pharmacologic or genetic inhibition of PGAM reduced Treg differentiation and suppressive function while reciprocally inducing markers of a pro-inflammatory, T helper 17 (Th17)-like state. The regulatory role of PGAM was dependent on the contribution of 3-phosphoglycerate (3 PG), the PGAM substrate, …

Characterization Of The Role Of Rsd-6, A Tudor Domain Protein, In Antiviral Rnai Pathway In Caenorhabditis Elegans, Krishna Prasad Dahal

LSU Doctoral Dissertations

RNA interference (RNAi) triggered by virus produced dsRNA intermediate offers robust innate immunity against invading viruses in plants, insects and animals. Caenorhabditis elegans has been extensively used as a model organism to study host virus interaction. Recently, a forward genetic screen identified RNAi spreading deficient-6 (RSD-6), a Tudor domain protein, as a key component in antiviral RNAi pathway against Orsay virus in C. elegans but its contribution in the pathway remained unclear. Here, we generated a rsd-6 null allele using CRISPR-Cas9 genome editing, crossed it with other known RNAi mutants and analyzed Orsay virus replication in them and in combination …

Optimal Water Hammer Protection Strategies For Low-Head Hydraulic Systems: A Case Study Using Bentley Hammer, Ahmed A. Abdel-Naby, Mostafa A. Abdel-Moaty, Eslam R. Lotfy

Mansoura Engineering Journal

The analysis of water hammer in low-head hydraulic systems holds significant importance compared to that in high-head systems, particularly given instances where Thorley’s equation may fall short in providing accurate pump inertia values. In situations where manufacturer data are unavailable, proactive measures to mitigate potential hammering incidents become imperative. While Bentley HAMMER software provides robust simulation capabilities, optimal protection strategies for low-head systems remain underexplored. This case study focuses on a scenario involving multistage centrifugal pumps that lift water from the basement floor of a building to its roof via a polypropylene pipeline. The investigation revealed a novel configuration: relocating …

Dietary Lipids Induce Ppard And Bcl6 To Repress Macrophage Il-23 Induction After Intestinal Injury And Lps Exposure, Ashleigh M Gil, Daniel F Zegarra-Ruiz, Wan-Jung Wu, Kendra Norwood, Adrien Assie, Buck S Samuel, Angela M Major, Gretchen E Diehl, Andrea A Hill Mcalester

Faculty, Staff and Students Publications

Unresolved tissue damage is a common feature of Inflammatory Bowel Disease (IBD) that facilitates disease progression. Here, we showed that high animal fat diets (HFD), an environmental risk factor associated with IBD pathogenesis, suppress intestinal macrophage production of critical tissue repair responses after damage. This includes reduced IL-23 production, which drives downstream production of IL-22, which is needed for barrier repair. Indicating that dietary lipids interfere with responses to microbial molecules needed to induce barrier protective functions, we found oleic acid could directly suppress macrophage Il23a induction after lipopolysaccharide (LPS) treatment. Deleting the lipid transporter CD36 on macrophages restored the …

Combination Of Irreversible Electroporation And Clostridium Novyi-Nt Bacterial Therapy For Colorectal Liver Metastasis, Zigeng Zhang, Guangbo Yu, Qiaoming Hou, Farideh Amirrad, Sha Webster, Surya M. Nauli, Jianhua Yu, Vahid Yaghmai, Aydin Eresen, Zhuoli Zhang

Pharmacy Faculty Articles and Research

Colorectal liver metastasis (CRLM) poses a significant challenge in oncology due to its high incidence and poor prognosis in unresectable cases. Current treatments, including surgical resection, systemic chemotherapy, and liver-directed therapies, often fail to effectively target hypoxic tumor regions, which are inherently more resistant to these interventions. This review examines the potential of a novel therapeutic strategy combining irreversible electroporation (IRE) ablation and Clostridium novyi-nontoxic (C. novyi-NT) bacterial therapy. IRE is a non-thermal tumor ablation technique that uses high-voltage electric pulses to create permanent nanopores in cell membranes, leading to cell death while preserving surrounding structures, and …
