Application Of Crispr/Cas9 Whole Genome Screens To Advance Macrophage Biology, Kevin Wanniarachchi

Electronic Theses and Dissertations

Advances in CRISPR/Cas9 gene editing technologies present opportunities to better understand the contribution of individual genes to complex eukaryotic cellular processes. I have applied CRISPR whole genome screen technologies to inform further mechanistic understanding of macrophage fitness and neutral lipid metabolism. This work is important because macrophages play critical roles in immune function and are implicated as causative agents in disease states. Chapter One of this dissertation provides insights into how CRISPR genome screening technologies have improved biological discovery and key findings from their application and discusses how this technology can be implemented to advance the discovery of novel macrophage …

C3 And C4 Grass Dominated Plant Communities Differ In Response To Future Larger And Less Frequent Rainfall, Zigeng Chen

Electronic Theses and Dissertations

Climate change is leading to larger and less frequent rainfall in the Northern Great Plains (NGP). We ask if this change in rainfall would influence carbon (C) and nitrogen (N) cycling in the NGP. First, we collected soils from C3 and C4 grass dominated plant communities from western South Dakota and conducted an incubation experiment to explore the effects of soil water content (SWC) and temperature on soil respiration (Rs) and N mineralization rate (ΔIN). Second, we conducted a three-year rainfallmanipulation (RaMP) experiment with two distinct rainfall regimes (frequent/small and infrequent/large events with constant total monthly precipitation) and two grasses …

Characterization Of Parp1-Dependent Poly-Adp-Ribosylation Of Sprtn, Quincee Simonson

Electronic Theses and Dissertations

DNA-protein crosslinks (DPCs) are a type of DNA lesion that form when proteins become covalently linked to DNA. It is estimated that replicating cells experience approximately 6,000 DPCs per day per genome during exponential growth (Ruggiano & Ramadan, 2021). If left unrepaired, DPCs can be lethal to cells. For this reason, cells have evolved multiple pathways to repair or bypass DPCs to survive. One such pathway involves SPRTN, a nuclear metalloprotease that plays a key role in the repair of DPCs through direct proteolysis (Lopez-Mosqueda et al., 2016; Vaz et al., 2016). Once SPRTN degrades the bulky protein component of …

Seroprevalence Of Sars-Cov-2 Antibodies Among Rural Healthcare Workers, Jordan Neises

Electronic Theses and Dissertations

The objective of this longitudinal cohort study was to determine the seroprevalence of antibodies to severe acute respiratory syndrome coronavirus-2 (SARSCoV- 2) in healthcare workers employed at healthcare clinics in three rural counties in eastern South Dakota and western Minnesota from May 13, 2020 through December 22, 2020. Three blood draws were performed at five clinical sites and tested for the presence of antibodies against the SARS-CoV-2 virus. Serum samples were tested for the presence of antibodies using a fluorescent microsphere immunoassay (FMIA), neutralization of SARS-CoV-2 Spike-pseudotyped particles (SARS-CoV-2pp) assay, and serum virus neutralization (SVN) assay. The seroprevalence was determined …

Chimeric Antigen Receptor T-Cell Therapy In Cancer, Brian Stahl

Biology and Microbiology Graduate Students Plan B Research Projects

The development of immune-checkpoint-inhibitors (ICIs) has led to promising advancements in the treatment of patients with cancers, leading with the use of cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) as a negative regulator of T cell activation in the mid-1990s. With the discovery of two ligands for program cell death protein-1 (PD-1) and promising checkpoint blockades in 2010, this sparked a cascade of hallmark immunotherapy drug patents, focusing on the mechanism of anti PD-1 and anti PD-L1 antibody inhibitors. Since then, chimeric antigen receptor (CAR)-engineered T (CAR-T) cells have emerged into the immuno-oncologic scene for treatment of hematological malignancies. These genetically …

A Review Of T1d: Prevalence, Current Therapies, And Cellular Therapies For The Future, Fahd Nazir

Biology and Microbiology Graduate Students Plan B Research Projects

Type 1 diabetes (T1D) is a chronic autoimmune disease that is characterized by the destruction of pancreatic β-cells and therefore, creating an insulin deficiency within the body. A deficiency of insulin within the body disrupts homeostatic glucose control leading to hyperglycemia and therefore, the need for exogenous insulin. Global incidence of T1D has been increasing for several decades and if current trajectory trends continue, incidence could double in the next year. In addition, diabetes is the seventh leading cause of death in the United States. Current therapies for the treatment of T1D include insulin injections, insulin-pump therapy, pancreatic transplant, and …

Interrelationships Of Systemic Changes In Hepatic Encephalopathy, Els Reuvekamp

Biology and Microbiology Graduate Students Plan B Research Projects

Hepatic encephalopathy is a temporary decline in mental function that is often associated with liver disease and/or portal-systemic disease. Hepatic encephalopathy (HE) symptoms can range from minor cognitive declines to coma and are known to result from excess ammonia accumulations in the blood stream subsequent to liver failure. While HE is known to result from hepatobiliary disorder, many of the physiological process underlying its development and progression remain to be elucidated. Recent studies have identified neurological, metabolic, and microbiome changes implicated in the disease state of HE. In this review, the roles of traditional pharmaceutical interventions and newly developing understandings …

Review Of A Chimeric Hemagglutinin-Based Influenza Vaccine Approach, Whitney Muck

Biology and Microbiology Graduate Students Plan B Research Projects

Influenza virus has affected human populations for centuries, causing an acute respiratory effect on the body. Even with scientific advancements in vaccine research, there are still serious limitations to the influenza vaccine. Varying strains and the constant recombination of the influenza virus has caused annual influenza circulation to be difficult to predict. The ongoing 40 race to develop a more efficient vaccine to broadly protect against the variety of influenza strains remains a public health priority. Many strategies have been studied to improve the current vaccine. The use of a chimeric hemagglutinin-based vaccine is in the first stages of human …

A Review Of Virus-Vectored Vaccines: Current Production Methods, Uses, Issues, And Future Perspectives, Jaden Marks

Biology and Microbiology Graduate Students Plan B Research Projects

Viral vector vaccines have recently risen to the forefront of vaccinology, but there are multiple factors that must be addressed before they achieve widespread approval and use. The concept of using viruses as vectors is not new, and numerous attempts to create vaccines that utilize virus vectors have been made in the past 25 years. Despite this, only one viral vector vaccine has gained full approval by the FDA. The goal of this review is to provide a comprehensive overview of the types of viral vector vaccines, production and purification methods, current and future viral vector vaccines, the issues and …

Alzheimer’S Disease: An Overview And Current Phase 3 Disease-Modifying Biologic Treatments, Haley Jahnke

Biology and Microbiology Graduate Students Plan B Research Projects

Alzheimer’s Disease (AD) is a degenerative brain disease caused by cell damage leading to brain changes such as amyloid plaques and neurofibrillary tangles. Alois Alzheimer was a clinical psychiatrist and neuroanatomist in Germany who first discovered Alzheimer’s Disease through microscopic viewing of Auguste D’s brain. Through more research following Dr. Alzheimer’s death, they began to stage AD. The six stages are: pre-clinical, mild, moderate, moderately severe, severe, and very severe. The current treatments approved by the FDA work to slow the progression of AD, rather than modify the disease. There are currently three Disease-Modifying Biologic clinical-trial drugs on the market …

Oral Microbiome And Its Effect On Respiratory Disease, Cole Pudwill

Biology and Microbiology Graduate Students Plan B Research Projects

The oral microbiome is composed of several different types of bacteria that can affect how our body operates. There are over 700 different bacteria living in our mouths. These bacteria can be helpful and harmful to our bodies, but they are synergistic in a way. There are several factors such as age, diet, smoking, and oral care that affect bacterial makeup. When there 10 is a significant difference, our immune system becomes weakened and respiratory disease set in. The immune system then works to return the microbiome back to homeostasis. When this fails, the diseases become chronic. Thus, the oral …

Non-Invasive Biomarkers For The Diagnosis Of Endometriosis And Polycystic Ovary Syndrome, Chandana Kamaraj

Biology and Microbiology Graduate Students Plan B Research Projects

Benign gynecological disorders can affect a high percentage of women of reproductive age, ages 15-44 years. These conditions can affect the lifestyle of the individual and can be associated with infertility. The gold standard to identify and diagnose endometriosis requires invasive surgical procedures, while the Rotterdam Criteria is used to identify and diagnose polycystic ovary syndrome. The purpose of this paper is to discuss, describe, and characterize potential non-invasive biomarkers that are present in various pathological stages of both endometriosis and polycystic ovary syndrome. These biomarkers include CA125, Serum galectin-9, hsa-miRNA-154-5p, miRNA-93, miRNA-320 and ET-1, miRNA-222, miRNA-146a, and miR-30c used …

Targeted Browsing With Goats For Eastern Redcedar (Juniperus Virginiana L.) Control, Alanna M. Hartsfield

Electronic Theses and Dissertations

As eastern redcedar (ERC) (Juniperus virginiana L.) grassland encroachment progresses, all potential control methods should be explored in the interest of Great Plains grassland health and longevity. Targeted browsing with goats has been proven as an effective control method on some juniper species; however, little is known about its ability to control ERC. These studies intend to mend knowledge gaps of how targeted browsing with goats control ERC by causing tree death without chemicals or machinery. The first study is two 3x3 Latin squares comparing protein-supplemented diets. The second study is a randomized complete block design of five 0.224 ha …

Development Of Genomic Resources In Vitis Riparia For Discoveries On Pre- And Post-Transcriptional Molecular Regulators Of Early Induction Into Endodormancy, Michael Robben

Electronic Theses and Dissertations

Grapevine is one of the most important fruit crops in the world, responsible for billions in global sales annually. The largest threat to grapevine and other crop production is global climate change resulting human activities. This brings unpredictable and drastic changes in ambient air temperatures to many climates in which grapes are grown. Lower temperatures and inclement weather are already responsible for millions in lost revenue due to tissue damage of established plants. Thus, protecting grapevine crops from weather-related damage is the biggest concern to growers aside from pathogen- and diseaserelated crop damage. The primary mechanism for winter survival in …

Identifying Adp-Ribosylation As The Biochemical Signal That Marks Dna-Protein Crosslinks For Sprtn-Dependent Proteolysis, Katelyn Hurley

Electronic Theses and Dissertations

DNA-protein crosslinks (DPCs) form when proteins covalently attach to DNA. It is estimated that hundreds of DPCs form in our cells each day. Because these lesions are cytotoxic, mammalian cells have evolved multiple intricate repair systems to remove DPCs and restore genome integrity. One mechanism mammalian cells rely on for DPC repair is direct proteolysis by the metalloprotease, SPRTN. While it is known that SPRTN degrades a heterogenous array of DPCs, including both naturally occurring and chemically induced, how SPRTN selects DPCs amongst chromatin-associated proteins remains unknown. Our main objective is to determine how DPC repair is regulated. In Chapter …

Modeling The Flow And Creep Compliance Properties Of Ice-Cream Mixes, Hiran Ranaweera

Electronic Theses and Dissertations

This work documented the influence of the protein source (MPC80 and WPC80), protein content (4-12%), and temperature (5-35ºC) on the rheological behavior (flow curve, frequency sweep, and creep-recovery) of ice-cream mixes (ICM). For each protein source, the viscosity of the ICM was satisfactorily modeled (𝑅2>0.98, 𝑅2 𝑎𝑑𝑗>0.98, and E0.99), while the recovery phase was represented by an empirical model. The percentage of recovery (%R) of the ICM significantly decreased with the protein content.

Characterizing The Lir Domain Of Abin1 And Identifying Its Role As A Regulator Of Mitophagy, Andrew Rhiner

Electronic Theses and Dissertations

A20 Inhibitor of NF-κB (ABIN1/TNIP1) is a known regulator of TNFα signaling induced cell death and inflammation. The regulatory activity has been attributed to ABIN1’s recruitment of the ubiquitin editing enzyme TNF-α-induced protein 3 (TNFAIP3/A20) to Receptor-interacting serine/threonine-protein kinase 1 (RIPK1). The regulation of RIPK1 by ABIN1 and A20 relies on a third player, linear ubiquitin chain assembly complex (LUBAC), which is involved in the recruitment of ABIN1 to RIPK1. Loss of LUBAC or ABIN1 is embryonic lethal, but loss of A20 is not embryonic lethal. The embryonic lethality due to loss of ABIN1, paired with the lack of lethality …

Exploring Bioprocessing Technologies For Diverse Industrial Application Of Canola, Ahmad Fawzi N Alhomodi

Electronic Theses and Dissertations

Globally, canola is the second largest oilseed crop after soybean, which is processed for the commercial production of high value oil. The industrial processing steps for canola oil extraction include preprocessing (cleaning, pressing, flaking, and cooking), mechanical pressing, and/or organic solvents. This process results in large quantities of protein-rich (~ 40% dry basis) meal as a co-product. The meal is used partially in animal diet (<30% inclusion) due to high levels of antinutritional factors (ANFs) such as high fibers, phytic acid, and glucosinolates, and low metabolizable energy. Thus, this research was designed to examine various bioprocessing technologies (i.e., traditional sprouting, solid state fermentation, submerged state fermentation, co-culture fermentation, mild pretreatments, and their combinations) for possible advancement in canola use. Canola seed sprouting for 6-day period led to an increase in protein content and a reduction in ANFs and oil content of sprouts compared to ungerminated seed. Subsequent submerged state fermentation of 6- day old sprouts using three different strains (Aureobasidium pullulans, Trichoderma reesei and Neurospora crassa) further increased protein content and lowered ANFs. Solid-state fermentation of 144 h old sprouts using A. pullulans, N. crassa and T. reesei enhanced the protein content and reduced ANFs of sprouts. Sprouting canola seed for three days helped in hull removal, leading to high protein meal accompanied by low fiber and phytic acid level. Three-day seed sprouting had no effect on oil yield, but free fatty acid content was higher compared to seed oil. Co-culture fermentation of HECM under solid state process showed maximum reduction in fiber content with co-culture of A. pullulans and N. crassa while a combination of A. pullulans and T. reesei promoted the highest GLS and phytic acid reductions compared to other combinations, which indicated the advantage of coculture inoculation over monoculture in terms of ANFs reduction. Mild pretreatment of HECM using deionized water resulted in washed HECM (WHECM) with lower soluble sugars and GLS compared to untreated HECM, whereas protein and amino acid were concentrated due to the removal of soluble components. WHECM compared to HECM showed higher protein digestibility when fed to rainbow trout. Subsequent mono- and coculture fermentation of HECM and WHECM under submerged process resulted in higher protein and amino acid content and lower ANFs levels compared to uninoculated controls. The results of cellulase, endoglucanase and β-glucosidase activity indicated the crucial role of used substrates, fungi, fermentation modes (solid state/submerged stated) and inoculation methods (mono-/co-culture) on enzyme activities.
