Exoenzyme Y Induces Extracellular Active Caspase-7 Accumulation Independent From Apoptosis: Modulation Of Transmissible Cytotoxicity, Phoibe Renema, Natalya Kozhukhar, Viktoriya Pastukh, Domenico Spadafora, Sunita Subedi Paudel, Dhananjay T. Tambe, Mikhail Alexeyev, Dara W. Frank, Troy Stevens

University Faculty and Staff Publications

Caspase-3 and -7 are executioner caspases whose enzymatic activity is necessary to complete apoptotic cell death. Here, we questioned whether endothelial cell infection leads to caspase-3/7-mediated cell death. Pulmonary microvascular endothelial cells (PMVECs) were infected with Pseudomonas aeruginosa (PA103). PA103 caused cell swelling with a granular appearance, paralleled by intracellular caspase-3/7 activation and cell death. In contrast, PMVEC infection with ExoY⁺ (PA103 ΔexoUexoT::Tc pUCPexoY) caused cell rounding, but it did not activate intracellular caspase-3/7 and it did not cause cell death. However, ExoY⁺ led to a time-dependent accumulation of active caspase-7, but not caspase-3, …

Here, we report the generation of a Cre-recombinase (iCre) transgenic rat, where iCre is driven using a vascular endothelial-cadherin (CDH5) promoter. The CDH5 promoter was cloned from rat pulmonary microvascular endothelial cells and demonstrated ~60% similarity to the murine counterpart. The cloned rat promoter was 2,508 bp, it extended 79 bp beyond the transcription start site, and it was 22,923 bp upstream of the translation start site. The novel promoter was cloned upstream of codon-optimized iCre and subcloned into a Sleeping Beauty transposon vector for transpositional transgenesis in Sprague-Dawley rats. Transgenic founders were generated and selected for iCre expression. Crossing …

Exploring The Relationships Between Mothers' Use Of Food To Soothe, Feeding Type And Mode, Maternal Feeding Style, Infant Behavior, And Infant Weight-Related Outcomes During Early Infancy, Megan K. Hupp

Master's Theses

Rapid infant weight gain (RWG) in the first six months postpartum is a strong predictor for obesity during childhood and adolescence. Although biological factors can influence infant weight gain trajectories, the modifiable factor of parent feeding practices can also have an influence. The use of food to soothe (FTS), or the act of feeding a child when he/she is upset for reasons other than hunger, has been associated with unhealthy eating behaviors and less-favorable weight outcomes in children and older infants. However, limited studies have explored the use of FTS during early infancy before the introduction of solids foods. The …

Snail Fever Of The Bladder In A Non-Endemic Area, Romana Idress, Zehra Jamil, Muhammad Areeb Ashfaq, Daniya Umer, Romana Idress, Hammad Ather

Department of Pathology and Laboratory Medicine

Schistosomiasis is rarely seen in Pakistan and is generally not very high on the list of differential diagnoses. However, it is an important cause of haematuria in certain endemic areas. It can affect multiple organs including the bladder, liver and lungs. We present a case of a young Pakistani male, travelling to and from Africa, who presented with complains of haematuria and suprapubic discomfort. Final pathologic diagnosis was urinary schistosomiasis (hematobium species). This case is particularly notable for the characteristic sago nodules identified on cystoscopy. It is important to consider schistosomiasis in the differential of haematuria in such scenarios as …

Lc-Ms Based Stability-Indicating Method For Studying The Degradation Of Lonidamine Under Physical And Chemical Stress Conditions, Ankit K. Rochani, Margaret A. Wheatley, Brian Oeffinger, John R. Eisenbrey, Gagan Kaushal

College of Pharmacy Faculty Papers

Background and purpose: Lonidamine is a hexokinase II inhibitor, works as an anticancer molecule, and is extensively explored in clinical trials. Limited information prevails about the stability-indicating methods which could determine the forced degradation of lonidamine under stressed conditions. Hence, we report the use of a rapid, sensitive, reproducible, and highly accurate liquid chromatography and mass spectrometry method to analyze lonidamine degradation. Experimental approach: The Xbridge BEH shield reverse phase C18 column (2.5 μm, 4.6 × 75 mm) using isocratic 50:50 water: acetonitrile with 0.1% formic acid can detect lonidamine with help of mass spectrometer in tandem with an ultraviolet …

The Effects Of Podcasts On Mental Health Stigma, Sarah N. Dure

Student Theses

Research indicates that media can have both negative and positive impacts on mental health stigma and self-stigma. No studies, to our knowledge, have examined the impact of audio media representation (podcasts) on mental health stigma. Our study therefore examines the effects that both positive and negative portrayals of mental illness in a news podcast would have on mental health stigma. We hypothesized that participants assigned to podcast conditions that primed for mental illness would lead participants to attribute an incident to mental illness. Additionally, we hypothesized that listening to a podcast that speaks negatively about individuals with mental illnesses would …

Development Of A Ct Metal Artifact Management Algorithm For Proton Therapy Planning (Ampp) For Head And Neck Cancer Patients, Daniela Branco

Dissertations and Theses (Open Access)

Purpose: Dental amalgams (high Z materials) are common sources of artifacts in Head and Neck (HN) images. Commercial artifact reduction techniques have been offered, but many are impractical, produce inaccurate CT images or are not clinically available, thus not widely implemented. The goal of this work is to use CT gantry tilts to develop and evaluate a stereoscopic HN metal artifact management algorithm and investigate its improvement in proton treatment planning.

Methods: The in-house CT metal artifact management method for proton planning (AMPP) uses two angled CT scans to generate a single image set with no metal artifacts posterior …

Characterization Of Treatment Planning System Photon Beam Modeling Errors In Iroc Houston Phantom Irradiations, Mallory Glenn

Dissertations and Theses (Open Access)

In radiation therapy, proper commissioning of the treatment planning system’s (TPS) dose calculation algorithm is critical because any errors in this process impact all treatment plans prepared in the system. Previously, TPS errors have been identified as a major cause for poor phantom irradiation performance, which may also mean that patients are treated suboptimally. The purpose of this work was to investigate the TPS beam modeling developed by the radiotherapy community to understand where inconsistencies may arise, which variables are most susceptible to variations, and in what way changing these variables can alter dose calculations.

Using the Imaging and Radiation …

Bringing Til Therapy Beyond Melanoma: Advancing The Treatment Of Advanced Pancreatic And Ovarian Cancers, Donald Sakellariou-Thompson

Dissertations and Theses (Open Access)

The success of checkpoint blockade immunotherapy (CBI) has reinvigorated the cancer therapy field, particularly for advanced melanoma which has doubled the survival rates compared to 20 years ago. However, there are many solid tumor types that are yet to receive substantial benefit from this groundbreaking therapy, two of which are pancreatic cancer (PDAC) and ovarian cancer (OvCa). As such, the 5-year survival rate for PDAC and OvCa stand at 9% and 28% respectively. Despite the lack of efficacy of CBI so far, there is still evidence for the role of immune control in these cancers as evidenced by presence of …

Directed Evolution Of Macrocyclic Peptides For Inhibition Of Autophagy, Joshua Gray

Dissertations and Theses (Open Access)

In recent decades it has become increasingly clear that induction of autophagy plays an important role in the development of treatment resistance and dormancy in many cancer types. Chloroquine (CQ) and hydroxychloroquine (HCQ), two autophagy inhibitors in clinical trials, suffer from poor pharmacokinetics and high toxicity at therapeutic dosages. This has prompted intense interest in the development of targeted autophagy inhibitors to re-sensitize disease to treatment with minimal impact on normal tissue. We utilized Scanning Unnatural Protease Resistant (SUPR) mRNA display to develop macrocyclic peptides targeting the autophagy protein LC3. The resulting peptides bound LC3A and LC3B—two essential components of …

Investigating The Role Of Quaking In Antigen Uptake And Cross-Presentation By Dendritic Cells, Yating Li

Dissertations and Theses (Open Access)

Dendritic cells (DCs) are considered the most potent antigen presenting cells (APC) due to their superior capability of cross-presenting exogenous antigens to CD8⁺ T cell for strong adaptive immune responses. They internalize foreign antigens by phagocytosis, endocytosis or macropinocytosis, which are then processed in endosomal compartments and loaded onto MHC Class I molecules. However, the molecular mechanisms regulating exogenous antigen uptake and cross-presentation by DCs are not fully understood.

In this study, we discovered that an RNA-binding protein, Quaking (QKI) plays a pivotal role in antigen uptake by DCs. Our previous studies in neural stem cells and microglia have …

Active Magnetic Radiation Shielding For Long-Duration Human Spaceflight, Kristine Ferrone

Dissertations and Theses (Open Access)

Exploration of interplanetary space presents dramatic hazards to human survival.

Space radiation hazards outside the protection of the Earth’s magnetosphere can

produce both acute and chronic health risks and thus become limiting factors for

NASA’s planned mission to Mars by the 2030s. Radiation exposure on a Mars mission

is delivered primarily by high energy ions from galactic cosmic rays and moderate

energy protons from solar particle events. The chronic radiation dose due to galactic

cosmic rays on a typical Mars mission is on the order of 1 Sv, and additional acute

radiation dose from solar flares can reach over 4 …

Targeting Unique Domains Of Lsd1 Regulates Pediatric Glioma Innate Immunity And Nk Cell Metabolism, Cavan Bailey

Dissertations and Theses (Open Access)

Regulation of chromatin accessibility is a key mechanism of cellular identity, allowing different tissues to develop using the same DNA template. Cancers will often hijack these epigenetic pathways, reactivating developmental genes to drive growth and deactivating tumor suppressor and immune recognition genes. Chromatin-modifying proteins deposit and remove chemical moieties from histone tails to aid in governing gene expression, and these proteins have become a new therapeutic target in cancer. Traditional chemotherapeutics aim to damage DNA, dysregulate cell division, or block hormonal growth signals, but epigenetic therapy can target vulnerabilities specific to cancer cells and broadly change gene expression patterns that …

Investigating The Metabolic Progression Of Glioblastoma With Hyperpolarized Magnetic Resonance, Travis Salzillo

Dissertations and Theses (Open Access)

Rapid diagnosis and therapeutic monitoring of aggressive diseases such as glioblastoma (GBM) can improve patient survival by providing physicians the time to optimally deliver treatment. This includes early in development, while the tumor is still manageable, or following initial therapy, when alternative treatments should be considered. The main goal of this project was to determine whether metabolic imaging with hyperpolarized magnetic resonance spectroscopy (MRS) could detect changes in tumor progression more rapidly than conventional anatomic magnetic resonance imaging (MRI) in patient-derived GBM murine models. To comprehensively capture the dynamic nature of cancer metabolism, in vivo pyruvate-to-lactate conversion with hyperpolarized MRI, …

Mechanistic Insights Into Vancomycin Resistance In Clostridioides Difficile, Ayesha Mahmood

Dissertations and Theses (Open Access)

C. difficile is a nosocomial, opportunistic pathogen that has become more hypervirulent over the last decade. Vancomycin is currently a frontline antibiotic for the treatment of C. difficile infections. Yet, strains of C. difficile are becoming non-susceptible to vancomycin. Emergence of the vancomycin non-susceptible phenotype has led to various questions including: What resistance elements are present that might contribute to the phenotype? Are these elements located on the chromosome or a plasmid? Where did these elements originate from? To address these questions, whole genome sequence analysis was performed to survey genes that may be involved in the vancomycin non-susceptible phenotype. …

Methods To Investigate Hyperthermia Induced By Tumor Treating Fields, Ruchi Singh

Dissertations and Theses (Open Access)

Tumor Treating Fields (TTFields) are an antineoplastic treatment delivered via application of alternating electric fields using insulated transducer arrays placed directly on the skin in the region surrounding the tumor. TTF’s is a non-invasive application of low-intensity (1-3 V/cm), intermediate-frequency (100-500 kHz) alternating electric fields. The predominant mechanism by which TTFields are thought to kill tumor cells is the disruption of mitosis through the depolymerization of microtubules and interruption of the spindle structure leading to mitotic catastrophe and the formation of non-viable daughter cells. Tumor Treating fields do not stimulate nerves and muscle because of their high frequency, and do …

Histological And Functional Characterization Of Cervical Spinal Cord Injury After Graded Contusion, Chrystine Gallegos

Dissertations and Theses (Open Access)

Most spinal cord injuries (SCIs) are cervical contusions and result in deficits for both locomotion and reaching and grasping functions. Previous studies have characterized histological and functional deficits in locomotion using primarily thoracic contusions, but most patients have cervical injuries. Damage to descending long spinal tracts (dLSTs) is one well-established cause of functional loss after SCI and has been explored in laceration and transection models, but these are not clinically relevant. In this study, I will explore the histological and functional deficits after graded cervical hemicontusion SCI and examine the potential contribution of different histological deficits to forelimb function after …

Statistical Methods For Resolving Intratumor Heterogeneity With Single-Cell Dna Sequencing, Alexander Davis

Dissertations and Theses (Open Access)

Tumor cells have heterogeneous genotypes, which drives progression and treatment resistance. Such genetic intratumor heterogeneity plays a role in the process of clonal evolution that underlies tumor progression and treatment resistance. Single-cell DNA sequencing is a promising experimental method for studying intratumor heterogeneity, but brings unique statistical challenges in interpreting the resulting data. Researchers lack methods to determine whether sufficiently many cells have been sampled from a tumor. In addition, there are no proven computational methods for determining the ploidy of a cell, a necessary step in the determination of copy number. In this work, software for calculating probabilities from …

Metagenomic, Viral And Host Genetic Analyses Of Congenital Tremor In Pigs, Kylee Marie Sutton

School of Biological Sciences: Dissertations, Theses, and Student Research

The Pestivirus genus contains several viral species having a major impact on the livestock species. While there were only four major pestiviral species for a time, recent metagenomic sequencing approaches identified additional species, such as atypical porcine pestivirus (APPV). Congenital tremor was first identified almost a hundred years ago and since still has an impact on swine health. There are two main types of congenital tremor, type A and B, with type A congenital tremor further subcategorized based on causative agent. Until recently, type A-II congenital tremor did not have a known cause. Recent viral sequencing of affected samples, including …

South Korea has achieved exceptional performance thus far: It has flattened the curve of new infections and brought the outbreak under control without imposing forceful measures such as lockdowns and travel ban. This commentary addresses the South Korean government’s response to COVID-19 and highlights distributed cognition and crisis management capabilities as critical factors. The authors discuss how the South Korean government has cultivated distributed …

How Do Intercrisis Learning Outcomes Affect Intracrisis Learning? “Learning In The Making” In The Case Of South Korea’S Covid-19 Response, Chongmin Na, Seulki Lee, Jungwon Yeo

Research Collection School of Social Sciences

This study explores the processes of intercrisis and intracrisis learning and the link between them, drawing on South Korea’s responses to the COVID-19 pandemic as an example. The crisis management literature suggests that intracrisis learning is less likely to occur than intercrisis learning due to inherent barriers that hinder learning and adaptation in the heat of crisis. Based on the conceptual framework of problem-oriented governance and crisis learning, we unpack how prominent outcomes of intercrisis learning facilitate intracrisis learning during the acute phase of an emerging crisis. We postulate that learning after 2015 MERS crisis developed the core capabilities for …
