Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines
Optimizing Itpa R178c Assays Via Hplc, Jared J. Reisnouer, Wally D. Pines
2026 Symposium
Two of the major nucleotide bases in DNA and RNA (Adenine and Guanine) are derived from the purine Inosine Monophosphate (IMP). IMP may occasionally form the noncanonical nucleotide Inosine Triphosphate (ITP) within the cell and become incorporated into DNA during replication, leading to potentially lethal errors. To combat this, human cells produce the “housekeeping” enzyme Inosine Triphosphatase (ITPA) to revert ITP to IMP. A mutation of this protein that replaces the 178th amino acid Arginine with Cysteine (R178C) is associated with a fatal infantile encephalopathy. Previous assessments of enzyme-substrate binding and catalysis for ITPA variants have been run at a …
Omani Camels From A Cultural And Genomics Perspective, Al Muatasim Al Zadjali
Omani Camels From A Cultural And Genomics Perspective, Al Muatasim Al Zadjali
Electronic Theses and Dissertations
The Dromedarian camel, Camelus dromedarius, is native to the Arabian Peninsula, including the Sultanate of Oman. These camels are used for food, milk, as well as show and racing competitions. Despite their economic and cultural importance research on camels in Oman is limited. The goal of this study was to examine their genomic variation, relationship with camels in other parts of the Arabian Peninsula, and to determine if selective breeding has led to the establishment of distinct breeds in Oman. Information was compiled from multiple sources to produce a comprehensive review on the breeding, management, economic and cultural use, …
Methamphetamine-Induced Dna Double-Stranded Breaks: The Impact Of The Dopamine Transporter And Insights Into The Mechanisms Of Dna Damage In Mouse Neuro 2a Cells, Lizette Couto
Dissertations, Theses, and Capstone Projects
Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …
The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson
The Biobehavioral Effects Of Embryonic Exposure To Neural Inflammation And Oxidative Stress In Zebrafish, Dalton J. Anderson
Honors College Theses
The purpose of this research is to improve understanding of the neurodevelopmental effects of embryonic exposure to elevated inflammation and oxidative stress induced by the antipyretic drug acetaminophen (APAP). Our study was the first to examine the interactive effects of APAP and inflammation in zebrafish embryos and how the treatments affect brain development and larval behavior. Experimental groups of zebrafish larvae were exposed to lipopolysaccharide (LPS) to induce inflammation, APAP, or LPS + APAP and larval behavior was analyzed using Ethovision automated behavioral tracking software. We also measured changes in whole-brain Glycogen Synthase Kinase 3 Beta (GSK3B) and GSK3B phosphorylation, …
Cul3 Negatively Regulates Nlrp12-Mediated Inhibition Of The Canonical Nf-Κb Signaling Pathway, Inyeong Lee
Cul3 Negatively Regulates Nlrp12-Mediated Inhibition Of The Canonical Nf-Κb Signaling Pathway, Inyeong Lee
Graduate Theses/Dissertations
Nod-like receptor family pyrin domain-containing protein 12 (NLRP12) is mainly known for its inhibitory function on NF-κB signaling in innate immune cells, and more recently, for its ability to regulate chemokine signaling and ubiquitination of the immune receptor RIG-I. Through a yeast 2-hybrid screen, the Lupfer lab previously discovered that NLRP12 interacts with other ubiquitin-associated proteins including Cullin 3 (CUL3) and RING finger protein 2 (RNF2). This research was conducted to mainly investigate the interaction between NLRP12 and CUL3 in human cells and examine the role in regulating NF-κB signaling. Previously, co-immunoprecipitation, followed by western blot analysis, and confocal microscopy …

Characterizing Cellular Injury And Inflammation With Aldob-/-Mouse Model Of Mafld, Andy Rashid
All Master's Theses
Metabolic-associated fatty liver disease (MAFLD) affects 1 in 3 people in the US and is a healthcare burden on the order of billions of dollars. MAFLD is characterized by pathological lipid accumulation in the liver, excess production of triglycerides and cholesterol, and export of LDL particles that raise serum lipid levels. These metabolic perturbations can lead to the development of liver fibrosis, chronic inflammation, and insulin resistance. Diagnosing MAFLD prior to fibrosis is crucial for successful intervention and prevention of advanced liver disease and other metabolic complications. Fructose-1Phospahte (F1P) accumulation from fructose overconsumption can drive hepatic lipogenesis and MAFLD progression. …
Analysis Of Hematocrit Levels In Walleye Sander Vitreus From Similar Waterbodies, Alyssa Hauser
Analysis Of Hematocrit Levels In Walleye Sander Vitreus From Similar Waterbodies, Alyssa Hauser
Journal of Earth and Life Science
Walleye Sander vitreus are a popular fish among anglers and hold a prominent place in Minnesotan’s identity as their state fish. Because of this, multiple management practices are used to ensure the continued health of their populations within Minnesota waters. In this study, the process of analyzing hematocrit levels was used to determine if the analysis of hematological parameters could be a useful tool in detecting differences in population health. To evaluate this, blood samples were acquired from age-0 and age-1 fish from two similar lakes and run through a hematocrit centrifuge to separate platelets from plasma to read the …
Understanding Intercellular Signaling During Lung Injury-Repair, Margo Patricia Cain
Understanding Intercellular Signaling During Lung Injury-Repair, Margo Patricia Cain
Dissertations and Theses (Open Access)
The mammalian lung is a complex system of specialized cell types with precise spatial organization designed to cooperate to perform gas exchange. These cell types together coordinate organ development, homeostasis, and repair after injury through signals either presented or secreted, known as ligands, to be received by receptors on the surface of another, or in some cases, the same cell. The alveolar region of the lung, the primary region of gas exchange, responds to various types of injuries with different lung repair mechanisms. In order to explore how the various cell types in the lung communicate to drive tissue repair …
The Significance Of Crispr/Cas9-Directed Cul3 Knockout On Human Colorectal Cancer Cells, Zoe A. Lautz
The Significance Of Crispr/Cas9-Directed Cul3 Knockout On Human Colorectal Cancer Cells, Zoe A. Lautz
Departmental Honors Projects
Cancer, the second leading cause of death in the US, is caused by mutations in select genes that alter cellular function leading to uncontrolled proliferation. Understanding the specific genes that drive cancer can lead to the generation of novel cancer therapies. To identify novel genes that drive cancer in the colon (CRC), lungs, and ovaries in mice, Starr et al. employed a transposon-based insertional mutagenesis system. One of the genes identified, APC, is mutated in 70-80% of human CRCs. CUL3, suspected to be a general driver gene, was discovered in the lung cancer screen. CUL3 was analyzed for its role …

Characterization Of The Infectivity Of Non-Replicating Human Immunodeficiency Virus (Hiv)-Derived Viral Vectors., Vanessa E. Rodriguez, Manuel Llano, Luis Valdes
COURI Symposium Abstracts, Summer 2012
The ability of HIV-derived viral vectors to integrate genes of interest into the host genome causing permanent phenotypic modifications makes them excellent tools in gene therapy. However, integration also causes insertional mutagenesis and controlling integration site selection will increase the biosafety of these molecular tools. HIV DNA integration site selection is influenced by LEDGF/p75, a chromatin-bound cellular protein that interacts with the viral enzyme integrase through the integrase binding domain (IBD). Integrase catalyzes viral DNA integration and non-covalently associates with the HIV genome forming the pre-integration complex (PIC). Therefore, interaction of chromatin-bound LEDGF/p75 with the PIC-associated integrase tethers the HIV …

The aim of this thesis was to investigate the effect of the VEGF family of growth factors and
cytokines TNF- α and IL-1β on oBRB function. The human RPE line ARPE-19 was
employed as an in vitro model of the oBRB. Two-Dimensional gel electrophoresis was
employed to study the effect of growth factors on the RPE proteome. The barrier properties of
the oBRB were evaluated by expression of the TJ proteins occludin or Zo-1, or claudins-1, 2,
3 and 4, determined by western blotting analysis. Claudins 2, 3 and 4 were found to be
significantly up-regulated by TNF-α, while interleukin …
