Elucidating The Interplay Between Sodium Selenite On The Tick Amblyomma Maculatum Selenoprotein Gene Expression, Afnan M. Beauti
Elucidating The Interplay Between Sodium Selenite On The Tick Amblyomma Maculatum Selenoprotein Gene Expression, Afnan M. Beauti
Honors Theses
Selenium (Se) is an element recognized as an essential micronutrient in eukaryote organisms. Selenoproteins contain selenium as selenocysteine, the 21st amino acid. Selenium plays a role in cell growth and functioning. At low concentrations, it can induce growth and at high concentrations, it can cause a cell to stop growing and potentially have toxic effects on the cell and organism. When selenium levels are high, oxidative stress results by the production of reactive oxidative species. Selenoproteins, however, can aid the antioxidant response in the cell. Ticks are arthropods of interest, as they are one of few that contain many selenogenes, …
Characterization Of Andrenocortical Tissue Morphology, Histology, And Steroid Synthesis Among Finetooth (Carcharhinus Isodon), Blacktip (Carcharhinus Limbatus), Atlantic Sharpnose (Rhizoprionodon Terraenovae), And Bonnethead (Sphyrna Tiburo) Sharks, Danielle Elizabeth Bailey
Master's Theses
Adrenocortical (interrenal) tissue is composed of steroidogenic cells that produce corticosteroids involved in the stress response and hydromineral balance. Previous research characterizing the elasmobranch interrenal suggests that the number of interrenal bodies that produce the single primary corticosteroid, 1a-hydroxycorticosterone (1a-OHB), varies among species. However, potential species-specific differences in the amount of interrenal tissue and major steroid products produced have been understudied. To address this critical gap in our understanding of elasmobranch biology, this study examined interrenal morphology, cell structure, steroidogenic enzyme distribution (3bHSD), and steroid production in four shark species: Finetooth Carcharhinus isodon, Blacktip Carcharhinus limbatus, Atlantic Sharpnose …
Disorder In Cysteine-Rich Granulin-3 And Its Implication In Alzheimer Disease, Gaurav Ghag
Disorder In Cysteine-Rich Granulin-3 And Its Implication In Alzheimer Disease, Gaurav Ghag
Dissertations
Granulins (GRNs) are a family of small, cysteine-rich proteins that are generated upon proteolytic cleavage of their precursor, progranulin (PGRN) during inflammation. All seven GRNs (1 – 7 or A – G) contain twelve conserved cysteines that form six intramolecular disulfide bonds, rendering this family of proteins unique. GRNs play multiple roles and are involved in a myriad of physiological as well as pathological processes. They are known to a play role in growth and embryonic development, wound healing, and signaling cascades as well as in tumorigenesis. They are also implicated in neurodegenerative diseases like frontotemporal dementia (FTD), Alzheimer disease …

Characterization Of P43lgrn-3, Kelly G. Hill
Honors Theses
Alzheimer’s Disease (AD) is a progressive neurodegenerative disorder characterized by extensive memory loss and cognitive deficits, which occur due to severe neuronal loss. Two hallmark lesions, intracellular neurofibrillary tangles composed of hyperphosphorylated tau and extracellular neuritic plaques formed by the aggregation of amyloid-β (Aβ), are responsible for the progressive neuronal loss seen in AD brains. Neurotoxic Aβ aggregates are also known to cause inflammation within the brain. It has recently come to light that severe and acute inflammation, such as seen in traumatic brain injury (TBI), may also lead to AD-type dementia. This has raised the question whether some of …
Uncovering The Identity And Metabolism Of Bacterial Coa-Rna, Joseph R. Spangler
Uncovering The Identity And Metabolism Of Bacterial Coa-Rna, Joseph R. Spangler
Dissertations
Coenzyme A is an indispensable molecule in all known life with roles in metabolism, gene regulation, and macromolecule synthesis. As CoA is derived from RNA itself, it’s incorporation into RNA by in vitro methods has proven useful in research probing the origin of life based on the RNA World theory. The discovery in contemporary bacteria of RNA modified with CoA, however, provided an unexpected twist to previously well-characterized bacterial systems. The identity of sequences associated with CoA-RNA has been elusive since their discovery in 2009 based on the difficulties in isolation while maintaining RNA quality. The aim of this study …
Generation Of Mutant Snap-23 To Arrest Mast Cell Degranulation At Trans-Snare Complex Formation, Suzette Wafford-Turner
Generation Of Mutant Snap-23 To Arrest Mast Cell Degranulation At Trans-Snare Complex Formation, Suzette Wafford-Turner
Honors Theses
Regulated secretion of pro-inflammatory molecules (e.g, histamines, proteases) from mast cells plays critical roles in immunity, allergic reactions, cardiovascular disease and cancer. These molecules are stored in secretory granules inside the cell and are rapidly released into the extracellular environment when mast cells are activated. It is known that mast cell degranulation depends upon membrane anchored SNAREs (soluble N-ethylmaleidimide-sensitive factor attachment protein receptors) and accessory proteins that form the trans-SNARE complex, a 4 helical bundle central to exocytic fusion. There are three SNARE proteins that contribute to the 4-helical bundle during exocytosis; Syntaxin and VAMP proteins each provide one helix …
The Preparation Of Synthetic Myod Mrna For Cellular Differentiation And Innate Immune Response Downstream Application, James D. Grenn
The Preparation Of Synthetic Myod Mrna For Cellular Differentiation And Innate Immune Response Downstream Application, James D. Grenn
Honors Theses
The development of therapeutic immune responses from the manipulation of embryonic stem cells (ESCs) via induction of synthetic RNA with 5’ capped and 3’ poly(A)tailed ends would lead to development of stem cell therapy. A necessary step in attaining such a goal is to first produce an mRNA transcript from a plasmid containing the open reading frame (ORF) for a transcription factor for cellular activation.
In this research, the DNA plasmid pMD4 encoding MyoD was transcribed into synthetic mRNA. The plasmid was first amplified using Polymerase Chain Reaction (PCR), and analyzed using gel electrophoresis. The amplified template was purified via …
Altering The Structure Of Carboxysomal Carbonic Anhydrase Csosca To Determine The Necessity Of The N-Terminal Domain In Csosca Function, Dana L. Dillistone
Altering The Structure Of Carboxysomal Carbonic Anhydrase Csosca To Determine The Necessity Of The N-Terminal Domain In Csosca Function, Dana L. Dillistone
Honors Theses
In this project, a DNA construct was designed and developed to remove the first fifty amino acids of the CsoSCA protein in the chemolithotrophic bacterium Halothiobacillus neapolitanus. The csoS3 gene codes for a carbonic anhydrase enzyme (CsoSCA) that is unique to a structure called a carboxysome. Carboxysomes are polyhedral microcompartments where carbon fixation is housed. The carbonic anhydrase is a shell-associated protein that improves the catalytic efficiency of ribulose-bisphosphate carboxylase/oxygenase (RuBisCO), the enzyme that catalyzes the fixation of carbon. By deleting the first fifty amino acids of the carbonic anhydrase, the necessity of the amino acids in carboxysome function was …
