Purification And Characterization Of An Anti-Basigin Monoclonal Antibody: Application To The Study Of Human Uterine Cells And Tissues, Jeannine M. Barna

All NMU Master's Theses

Between 1990 and 2017, the global rate of female infertility increased by over 15% (Sun et al., 2019). An embryo's failure to implant into the uterus is the primary cause of early pregnancy loss. Several studies have identified molecules necessary for successful implantation, but their function during implantation remains poorly understood (S. Zhang et al., 2013). The cell surface glycoprotein basigin-2 is necessary for embryo implantation in the mouse and plays a role in several cellular functions, including cell communication and extracellular matrix remodeling (Chen et al., 2009; K. Li & Nowak, 2020). In vitro studies using human uterine cells …

Modification Of The Tumor Microenvironment Enhances Anti-Pd-1 Immunotherapy In Metastatic Melanoma, Guilan Shi, Megan Scott, Cathryn G. Mangiamele, Richard Heller

Bioelectrics Publications

Resistance to checkpoint-blockade treatments is a challenge in the clinic. Both primary and acquired resistance have become major obstacles, greatly limiting the long-lasting effects and wide application of blockade therapy. Many patients with metastatic melanoma eventually require further therapy. The absence of T-cell infiltration to the tumor site is a well-accepted contributor limiting immune checkpoint inhibitor efficacy. In this study, we combined intratumoral injection of plasmid IL-12 with electrotransfer and anti-PD-1 in metastatic B16F10 melanoma tumor model to increase tumor-infiltrating lymphocytes and improve therapeutic efficacy. We showed that effective anti-tumor responses required a subset of tumor-infiltrating CD8⁺ and CD4 …

Regulation Of Tissue Mechanics And Adherens Junctions By Small Gtpase Rhoa During Drosophila Embryogenesis, Hanqing Guo

Dartmouth College Ph.D Dissertations

Actomyosin contractility plays an important role at both the cell and tissue level during developments. In this study, we developed an optogenetic tool that can acutely inhibit actomyosin contractility by targeting its main activator Rho1. This optogenetic tool can achieve myosin inhibition within one minute and thus enable further dissection of actomyosin function in development. In my first two projects, I used Drosophila mesoderm invagination (also known as ventral furrow formation) as a model to study epithelial folding, a fundamental mechanism for constructing complex 3D tissues. Apical constriction mediated by actomyosin contractility is a common mechanism for epithelial folding. However, …

Advances In 3d Culture Systems For Therapeutic Discovery And Development In Brain Cancer, Janith Wanigasekara, Patrick J. Cullen, Paula Bourke, Brijesh Tiwari, James F. Curtin

This review focuses on recent advances in 3D culture systems that promise more accurate therapeutic models of the glioblastoma multiforme (GBM) tumor microenvironment (TME), such as the unique anatomical, cellular, and molecular features evident in human GBM. The key components of a GBM TME are outlined, including microbiomes, vasculature, extracellular matrix (ECM), infiltrating parenchymal and peripheral immune cells and molecules, and chemical gradients. 3D culture systems are evaluated against 2D culture systems and in vivo animal models. The main 3D culture techniques available are compared, with an emphasis on identifying key gaps in knowledge for the development of suitable platforms …

Impacts Of Intermediate And Long-Term Vitamin D Deficiency On The Murine Gastric Epithelial Cells And Acid Secretion, Shaima Raji Sirajudeen

Dissertations

The biological functions of vitamin D (VD) are diverse. It influences immunological response, cell proliferation and differentiation, and calcium homeostasis. However, over one billion people globally are VD deficient. The VD receptors, VDR and PDIA3, mediate the biological activities of VD. Studies on the biological roles of VD are numerous but very little on the stomach. The stomach is divided into three main parts – forestomach, corpus and antrum. Gastric glands, which make up the functional units of the stomach, are made up of numerous cell lineages and are located in the corpus and antrum, which are the glandular parts …

Successful Use Of Continuous Erector Spinae Plane Blocks In A Patient With Variant Angina After Large Ventral Hernia Repair, Alexandra L Belfar, Yi Deng, Raymond C Yu, Annas Sabbagh

Faculty, Staff and Students Publications

Coronary artery spasm constitutes the primary underlying pathology of variant angina. Because provocation of coronary artery spasm may occur with both excess sympathetic and excess parasympathetic stimulation, patients with this disorder have extremely limited options for perioperative pain control. This is especially true for procedures involving extensive abdominal incision/manipulation. Whereas neuraxial analgesia might otherwise be appropriate in these cases, several studies have demonstrated that coronary artery spasm can occur as a result of epidural placement, and therefore, that this may not be an optimal choice for patients with variant angina. This report discusses the case of a patient with a …

Whole Genome Sequencing Of Moraxella Bovis Strains From North America Reveals Two Genotypes With Different Genetic Determinants, Emily L. Wynn, Matthew M. Hille, John Dustin Loy, Gennie Schuller, Kristen L. Kuhn, Aaron M. Dickey, James L. Bono, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

Background: Moraxella bovis and Moraxella bovoculi both associate with infectious bovine keratoconjunctivitis (IBK), an economically significant and painful ocular disease that affects cattle worldwide. There are two genotypes of M. bovoculi (genotypes 1 and 2) that differ in their gene content and potential virulence factors, although neither have been experimentally shown to cause IBK. M. bovis is a causative IBK agent, however, not all strains carry a complete assortment of known virulence factors. The goals of this study were to determine the population structure and depth of M. bovis genomic diversity, and to compare core and accessory genes and …

Hyperexcitable And Immature-Like Neuronal Activity In The Auditory Cortex Of Adult Rats Lacking The Language-Linked Cntnap2 Gene., Kaela E Scott, Rajkamalpreet S Mann, Ashley L Schormans, Susanne Schmid, Brian L Allman

Anatomy and Cell Biology Publications

The contactin-associated protein-like 2 gene, CNTNAP2, is a highly penetrant risk gene thought to play a role in the genetic etiology of language-related disorders, such as autism spectrum disorder and developmental language disorder. Despite its candidacy for influencing language development, few preclinical studies have examined the role of CNTNAP2 in auditory processing. Using in vivo and in vitro electrophysiological recordings in a rat model with translational validity, we report that a loss of the Cntnap2 gene function caused immature-like cortical evoked potentials, delayed multiunit response latencies to acoustic stimuli, impaired temporal processing, and led to a pattern of hyperexcitability in …

Host-Level Susceptibility And Irf1 Expression Influence The Ability Of Ifn-Γ To Inhibit Kshv Infection In B Lymphocytes, Nedaa Alomari, Jennifer Totonchy

Pharmacy Faculty Articles and Research

Kaposi’s sarcoma-associated herpesvirus (KSHV) is associated with vascular endothelial cell tumor, Kaposi’s sarcoma (KS) and lymphoproliferative disorder, multicentric Castleman’s disease (MCD), primary effusion lymphoma (PEL) and KSHV inflammatory cytokine syndrome (KICS). Dysregulation of proinflammatory cytokines is found in most KSHV associated diseases. However, little is known about the role of host microenvironment in the regulation of KSHV establishment in B cells. In the present study, we demonstrated that IFN-γ has a strong inhibitory effect on KSHV infection but only in a subset of tonsil-derived lymphocyte samples that are intrinsically more susceptible to infection, contain higher proportions of naïve B cells, …

Chemical Relaxers And Hair-Straightening Products: Potential Targets For Hormone-Related Cancer Prevention And Control, Adana A. M. Llanos, Jasmine A. Mcdonald, Dede K. Teteh, Traci N. Bethea

Health Sciences and Kinesiology Faculty Articles

"Emerging data show that use of permanent hair dyes, chemical relaxers, and straightening products might contribute to increased risk of hormone-related cancers (1-5) and potentially breast tumors with features indicative of more aggressive phenotypes (6). Given the wide use of these products globally, they are an important source of exposure to potentially harmful chemicals, including endocrine-disrupting chemicals—to which we are ubiquitously exposed (7)—and mutagenic and/or genotoxic compounds. The unequal burden of exposure across populations plausibly contributes to cancer inequities as the groups with the greatest exposure also experience poorer cancer outcomes (8). …

Locating Mutagen-Sensitivity Gene Mus109 In The Drosophila Melanogaster Genome Using Deficiency Mapping, Chandani Mitchell

The Winthrop McNair Research Bulletin

The complex processes involved in repairing damaged DNA are still being elucidated. Some genes that are known to have roles in the DNA repair process have been identified, such as the mutagen-sensitivity genes, or mus genes, in Drosophila melanogaster. However, the precise genomic location of some mus genes is still unknown, including mus109. It is known that mutations in mus109 cause chromosomal aberrations resulting in larval death, and previous research has mapped mus109 to a region of the X chromosome consisting of over 520,000 nucleotides and 41 genes. Therefore, this study aimed to locate mus109 using deficiency mapping. The mus109D2 …

Activity Of The Lactate Dehydrogenase Inhibitor Oxamic Acid Against The Fermentative Bacterium Streptococcus Mitis/Oralis: Bactericidal Effects And Prevention Of Daptomycin Resistance In Vitro And In An Ex Vivo Model, Razieh Kebriaei, Arnold S. Bayer, Christian K. Lapitan, Michael J. Rybak, Greg A. Somerville, Nagendra N. Mishra

School of Veterinary and Biomedical Sciences: Faculty Publications

Streptococcus mitis/oralis is a fermentative bacterium that relies on lactate dehydrogenase to balance its redox poise and keep glycolysis active. Metabolomic analysis of an in vitro– derived daptomycin-resistant (DAP-R) S. mitis/oralis strain (351-D10) revealed differences in glucose catabolism relative to its DAP-susceptible (DAP-S) parental strain, 351. Metabolic changes associated with the transition to this DAP-R phenotype suggested that inhibiting glycolysis could alter DAP susceptibility. In addition, the strong reliance of S. mitis/oralis on glycolysis for energy and biosynthetic intermediates suggested that inhibiting glycolysis would adversely affect growth and biomass accumulation. To test these hypotheses, we used the lactate dehydrogenase inhibitor …

Ngly1 Deficiency Affects Glycosaminoglycan Biosynthesis And Wnt Signaling Pathway In Mice, Amy Batten

PANDION: The Osprey Journal of Research and Ideas

Individuals affected by NGLY1 Deficiency cannot properly deglycosylate and recycle certain proteins. Even though less than 100 people worldwide have been diagnosed with this rare autosomal recessive condition, thousands are affected by similar glycosylation disorders. Common phenotypic manifestations of NGLY1 Deficiency include severe neural and intellectual delay, impaired muscle and liver function, and seizures that may become intractable. Very little is currently known about the various mechanisms through which NGLY1 deficiency affects the body and this has led to a lack of viable treatment options for those afflicted. This experiment uses a loss-of-function (LOF) mouse model of NGLY1 Deficiency homologous …

Mutant C. Elegans P53 Together With Gain-Of-Function Glp-1/Notch Decreases Uvc-Damage-Induced Germline Cell Death But Increases Parp Inhibitor-Induced Germline Cell Death, Jorge Canar, Prima Manandhar-Sasaki, Jill Bargonetti

Publications and Research

The TP53 gene is mutated in over 50% of human cancers, and the C. elegans p53-1 (cep-1) gene encodes the ortholog CEP-1. CEP-1 is activated by ultraviolet type C (UVC)-induced DNA damage and activates genes that induce germline apoptosis. UVC treatment of gain-of-function glp-1(ar202gf)/Notch tumorous animals reduces germline stem cell numbers (and overall tumor size), while UVC treatment of double-mutant cep-1/p53(gk138);glp-1/Notch(ar202gf) increases DNA damage adducts and stem cell tumor volume. We compared UVC-induced mitotic stem cell death and animal lifespans for the two different C. elegans tumorous strains. C. elegans stem cell compartment death has never been observed, and we …

The Genetics Of Skin Cancer: What Genes Drive The Development Of Basal Cell Carcinoma, Squamous Cell Carcinoma, And Melanoma?, Cassandra Poole, Abagail Pack, Elizabeth Whitehead, Virginia Marshall

Fall Showcase for Research and Creative Inquiry

Skin cancer is one of the most common forms of cancer worldwide. The American Academy of Dermatology estimates that 9500 people in the United States are diagnosed with skin cancer every day, and that 1 in 5 Americans will be diagnosed with skin cancer by age 70. With such a high prevalence of disease, understanding how skin cancer develops and how it can be treated is extremely important. This project aims to analyze the genes involved in the development of the three most common forms of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.

Glutathione And Glutaredoxin In Redox Regulation And Cell Signaling Of The Lens, Marjorie F. Lou

School of Veterinary and Biomedical Sciences: Faculty Publications

The ocular lens has a very high content of the antioxidant glutathione (GSH) and the enzymes that can recycle its oxidized form, glutathione disulfide (GSSG), for further use. It can be synthesized in the lens and, in part, transported from the neighboring anterior aqueous humor and posterior vitreous body. GSH is known to protect the thiols of the structural lens crystallin proteins from oxidation by reactive oxygen species (ROS) so the lens can maintain its transparency for proper visual function. Age-related lens opacity or senile cataract is the major visual impairment in the general population, and its cause is closely …

Leaf Phenology And Freeze Tolerance Of The Invasive Tree Pyrus Calleryana (Roseaceae) And Potential Native Competitors, Margaret E. Maloney, Abby Hay, Eric B. Borth, Ryan W. Mcewan

Biology Faculty Publications

Pyrus calleryana is one of the most problematic invasive species in the eastern United States. The mechanisms that enable Py. calleryana to establish and outcompete native plants are not fully understood but likely include a profile of advantageous traits. Extended leaf phenology is a characteristic noted in many woody invasive plants. Leaf phenology of Py. calleryana and two native woody species, Populus deltoides and Platanus occidentalis, was observed in natural areas near Dayton, OH from December 2019 to November 2020. A frost event in May also gave us the serendipitous opportunity to assess frost tolerance of these species. We …

The Trichloroethylene Metabolite S-(1,2-Dichlorovinyl)-L-Cysteine Inhibits Lipopolysaccharide-Induced Inflammation Transcriptomic Pathways And Cytokine Secretion In A Macrophage Cell Model, Sean M. Harris, Kelly M. Bakulski, John Dou, Ethan Houskamp, Eleanor Scheeres, Emily Schellenboom, Olivia Harlow, Rita Loch-Caruso, Erica Boldenow

University Faculty Publications and Creative Works

Studies have shown that the trichloroethylene metabolite S-(1,2-dichlorovinyl)-l-cysteine (DCVC) inhibits cytokine secretion in pathogen stimulated fetal membrane tissue but little is known about the mechanism for these effects, including which cell types or transcriptomic pathways are impacted. Macrophages play a critical role in fetal membrane immune responses during infection. We tested the hypothesis that DCVC inhibits lipopolysaccharide (LPS) stimulated inflammation pathways in macrophage-like THP-1 cells. We treated THP-1 cells for 24 h then treated with 1, 5, or 10 μM DCVC for 24 h. After a 4 h incubation with lipopolysaccharide (LPS), we collected RNA and cell media. We performed …

A Review On Serum, Genetic And Mirna Associated Biomarkers For The Early Diagnosis Of Hepatocellular Carcinoma (Hcc)), Ambreen Kanwal, Asima Tayyeb

Journal of Bioresource Management

Hepatocellular carcinoma is the most devastating complication of liver cirrhosis and diagnosis in earlier stages could be useful in curative interventions. The main aim of this review was to analyze current diagnostic biomarkers which are available for the early diagnosis of hepatocellular carcinoma (HCC). For this purpose, we searched different web databases including Medline/Pubmed. We found multiple significant serum biomarkers for imperative diagnosis including α- Fetoprotein, Des- γ -carboxyprothrombin (DCP), Osteopontin (OPN), Glypican-3 (GPC3), Golgi protein-73 (GP73), Squamous cell carcinoma antigen (SCCA), Annexin A2 (ANXA2) and Heat shock protein 70 (HSP70) but all of these represent low sensitivity and low …

Recent Emergence Of Bovine Coronavirus Variants With Mutations In The Hemagglutinin-Esterase Receptor Binding Domain In U.S. Cattle, Aspen M. Workman, Tara G. Mcdaneld, Gregory P. Harhay, Subha Das, John Dustin Loy, Benjamin M. Hause

School of Veterinary and Biomedical Sciences: Faculty Publications

Bovine coronavirus (BCoV) has spilled over to many species, including humans, where the host range variant coronavirus OC43 is endemic. The balance of the opposing activities of the surface spike (S) and hemagglutinin-esterase (HE) glycoproteins controls BCoV avidity, which is critical for interspecies transmission and host adaptation. Here, 78 genomes were sequenced directly from clinical samples collected between 2013 and 2022 from cattle in 12 states, primarily in the Midwestern U.S. Relatively little genetic diversity was observed, with genomes having >98% nucleotide identity. Eleven isolates collected between 2020 and 2022 from four states (Nebraska, Colorado, California, and Wisconsin) contained a …

Seqcode: A Nomenclatural Code For Prokaryotes Described From Sequence Data, Brian P. Hedlund, Maria Chuvochina, Philip Hugenholtz, Konstantinos T. Konstantinidis, Alison E. Murray, Marike Palmer, Donovan H. Parks, Alexander J. Probst, Anna-Louise Reysenbach, Luis M. Rodriguez-R, Ramon Rossello-Mora, Iain C. Sutcliffe, Stephanus N. Venter, William B. Whitman

Life Sciences Faculty Research

Most prokaryotes are not available as pure cultures and therefore ineligible for naming under the rules and recommendations of the International Code of Nomenclature of Prokaryotes (ICNP). Here we summarize the development of the SeqCode, a code of nomenclature under which genome sequences serve as nomenclatural types. This code enables valid publication of names of prokaryotes based upon isolate genome, metagenome-assembled genome or single-amplified genome sequences. Otherwise, it is similar to the ICNP with regard to the formation of names and rules of priority. It operates through the SeqCode Registry (https://seqco.de/), a registration portal through which names and …

Targeting Of The Hedgehog Signaling Pathway In Cancer Treatment, Andrew J. Hawes

The Cardinal Edge

The Hedgehog (Hh) signaling pathway is a developmental pathway that is highly conserved evolutionarily. While typically only displaying high activity during embryogenesis, overactivation of the Hh pathway in adults has been linked to multiple forms of cancer including acute myeloid leukemia, myelofibrosis, basal-cell carcinoma, pancreatic ductal adrenal carcinoma, and triple negative breast cancer. The prevalence of Hh activation in many different cancers has made it a prime target for inhibition of these cancers through novel therapies. This literature review sought to assess the current state of cancer treatment through inhibition of Hh signaling. Most current clinical trials involving the pathway …

Planning System For The Optimization Of Electric Field Delivery Using Implanted Electrodes For Brain Tumor Control, Erin Iredale, Brynn Voigt, Adam Rankin, Kyungho W Kim, Jeff Z Chen, Susanne Schmid, Matthew O Hebb, Terry M Peters, Eugene Wong

Anatomy and Cell Biology Publications

BACKGROUND: The use of non-ionizing electric fields from low-intensity voltage sources (< 10 V) to control malignant tumor growth is showing increasing potential as a cancer treatment modality. A method of applying these low-intensity electric fields using multiple implanted electrodes within or adjacent to tumor volumes has been termed as intratumoral modulation therapy (IMT).

PURPOSE: This study explores advancements in the previously established IMT optimization algorithm, and the development of a custom treatment planning system for patient-specific IMT. The practicality of the treatment planning system is demonstrated by implementing the full optimization pipeline on a brain phantom with robotic electrode implantation, postoperative imaging, and treatment stimulation.

METHODS: The integrated planning pipeline in 3D Slicer begins with importing and segmenting patient magnetic resonance images (MRI) or computed tomography (CT) images. The segmentation process is manual, followed by a semi-automatic smoothing step that allows …

Determining The Roles Of The Oligomerization And C-Terminal Domains In Mutant P53 Gain-Of-Function Activities, George K. Annor

Dissertations, Theses, and Capstone Projects

The tumor suppressor p53 (TP53) gene is often mutated in cancer, with missense mutations found in the central DNA binding domain, and less often in the oligomerization domain (OD) and C-terminal domain (CTD). The OD and CTD have been found to be critical for the tumor suppressor functionality of wild-type p53 (wtp53). Specific missense mutations in the DNA binding domain have been found to confer new gain-of-function (GOF) activities. Mutations that destabilize tetramer formation, or deletion of key lysine residues within the CTD, downregulate the ability of wtp53 to transactivate (increase the rate of transcription of) its target …
