Veterinary Science Faculty Publications

Infection with Helicobacter pylori is the single greatest risk factor for developing gastric adenocarcinoma. In prospective, population-based studies, seropositivity to the uncharacterized H. pylori proteins Hp0305 and Hp1564 was significantly associated with cancer risk in East Asia. However, the mechanism underlying this observation has not been elucidated. Here, we show that Hp0305 and Hp1564 act in concert with previously ascribed H. pylori virulence mechanisms to orchestrate cellular alterations that promote gastric carcinogenesis. In samples from 546 patients exhibiting premalignant gastric lesions, seropositivity to Hp0305 and Hp1564 was significantly associated with increased gastric atrophy across all stomach conditions. In vitro, …

From Inner Segment To Outer Segment: Palmitoylation Of Photoreceptor Na+, K+-Atpase And The Importance Of Prcd In Photoreceptor Outer Segment Morphogenesis, Emily R. Sechrest

Graduate Theses, Dissertations, and Problem Reports (ETD)

Photoreceptors are specialized neuroepithelial cells which are optimized for efficient capture of light and initiation of visual transduction. These cells have several compartments which are very important for proper visual function and segregation of cellular processes, including the outer segment (OS), inner segment (IS), nucleus, and synapse. The IS houses all of the cellular organelles and biosynthetic molecular machinery the cell requires and is the site of protein synthesis. The light-sensing OS is a highly modified, primary cilium, which contains many stacks of double membranous discs which house proteins required for formation and maintenance of OS structure, as well as …

Towards A New Method Of Determining Protein Structure, Niloofar Abolhasani Khaje

Electronic Theses and Dissertations

Hydroxyl radical protein footprinting (HRPF) by fast photochemical oxidation of proteins (FPOP) is a mass spectrometry-based technique that measures the apparent protein oxidation rate by freely diffusing hydroxyl radicals at different regions in a protein, and correlates changes in this apparent rate with changes in the solvent accessibility of the protein target based on quantifying the amount of oxidation of different regions of a protein. While there have been many advancements in HRPF-FPOP, oxidation measurement still suffers from high variability between measurements. High variability reduces the power statistical power this technique even in the presence of radical dosimetry measurements and …

Design And Synthesis Of Salvinorin-Based Compounds For The Opioid Receptors., Nicholas S. Akins

Electronic Theses and Dissertations

Opioid receptors (OR) are expressed throughout both the peripheral and central nervous system and play crucial roles in the modulation of antinociception, addiction, anxiety, and depression. Salvinorin A, the main isolate of the hallucinogenic plant Salvia divinorum, is one of the most potent naturally occurring kappa opioid receptor agonists. Salvinorin A possesses beneficial effects as a therapeutic in a variety of CNS disorders, but due to its strong hallucinating, anxiogenic effects, and short half-life(t1/2), it has never advanced to clinical trials. Instead, salvinorin A has been used as an important prototype for the development of related drug candidates. Our initial …

An In-Depth Approach For Functional Oligosaccharide Analysis, Hao Liu

Electronic Theses and Dissertations

Heparin and heparan sulfate (Hp/HS) are linear complex glycosaminoglycans (GAGs), which are involved in diverse biological processes. Although Hp/HS GAGs influence numerous physiological and pathophysiological processes, their high degree of size polydispersity and sequence microheterogeneity make structure-function characterization challenging. In addition, it is hard to understand the structures that underlie any of the various functions with MS, because of the lability of the sulfate group during tandem mass spectrometry (MS/MS) analysis. The work presented here describes an in-depth approach for functional oligosaccharide characterization including chemical derivatization of Hp to inhibit COVID-19 infection, multi-dimensional liquid chromatography (LC) fractionation method, chemical derivatization …

Bisphosohoglycertae Mutase: A Potential Target For Sickle Cell Disease, Anfal S. Aljahdali

Theses and Dissertations

Bisphosphoglycerate mutase (BPGM) is a part of the erythrocyte glycolysis system. Specifically, it is a central enzyme in the Rapoport-Leubering pathway, a side glycolytic pathway involved in the regulation of the concentration of the natural allosteric effector of hemoglobin (Hb), 2,3-bisphosphoglycerate (2,3-BPG). BPGM catalyses the synthesis and hydrolysis of 2,3-BPG through its synthase and phosphatase activities. The synthase activity is the main role of BPGM, while the phosphatase activity is low and is activated by the physiological effector, 2-phosphoglycolate (2-PG) with the latter mechanism poorly understood.

BPGM activity and 2,3-BPG levels in red blood cells (RBCs) have a significant role …

Glycosaminoglycan Modulation Of Key Proteins In Alzheimer's Disease, Tamim Chiba

Theses and Dissertations

Glycosaminoglycans (GAGs) are linear polysaccharides whose disaccharide building blocks consist of an amino sugar (D-glucosamine) and either uronic acid (D-glucuronic acid or L-iduronic acid) or galactose. Nearly all GAGs (with the exception of hyaluronic acid) are covalently attached to proteins, forming proteoglycans, and are ubiquitous in nature. The monomeric units, chain length, degree and pattern of sulfation, and epimerization are important properties that determine the influence of these molecules. Through Coulombic forces, hydrogen bonds and hydrophobic interactions, they regulate many physiological and pathophysiological processes such as blood coagulation, cell growth and differentiation, inflammatory processes, host defense and viral infection mechanisms. …
