Inhibition Of Zika Virus Replication By G-Quadruplex-Binding Ligands, Prativa Majee, Aryamav Pattnaik, Bikash R. Sahoo, Uma Shankar, Asit K. Pattnaik, Amit Kumar, Debasis Nayak

School of Veterinary and Biomedical Sciences: Faculty Publications

Zika virus (ZIKV), a mosquito-transmitted Flavivirus, emerged in the last decade causing serious diseases and affecting human health globally. Currently, no licensed vaccines or antivirals are available to combat ZIKV, although several vaccine candidates are in the pipeline. In recent years, the presence of non-canon- ical G-quadruplex (GQ) secondary structures in viral genomes has ignited significant attention as potential targets for anti- viral strategy. In this study, we identified several novel conserved potential GQ structures by analyzing published ZIKV genome sequences using an in-house algorithm. Bio- physical and biochemical analysis of the RNA sequences con- taining these potential GQ sequences …

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 …

Human Retinal Organoids Release Extracellular Vesicles That Regulate Gene Expression In Target Human Retinal Progenitor Cells, Jing Zhou, Miguel Flores‑Bellver, Jianbo Pan, Alberto Benito‑Martin, Cui Shi, Onyekwere Onwumere, Jason Mighty, Jiang Qian, Xiufeng Zhong, Tasmim Hogue, Baffour Amponsah‑Antwi, Linda Einbond, Rajendra Gharbaran, Hao Wu, Bo‑Juen Chen, Zhiliang Zheng, Tatyana Tchaikovskaya, Xusheng Zhang, Hector Peinado, Maria Valeria Canto‑Soler, Stephen Redenti

The mechanisms underlying retinal development have not been completely elucidated. Extracellular vesicles (EVs) are novel essential mediators of cell‑to‑cell communication with emerging roles in developmental processes. Nevertheless, the identification of EVs in human retinal tissue, characterization of their cargo, and analysis of their potential role in retina development has not been accomplished. Three‑dimensional retinal tissue derived from human induced pluripotent stem cells (hiPSC) provide an ideal developmental system to achieve this goal. Here we report that hiPSC‑derived retinal organoids release exosomes and microvesicles with small noncoding RNA cargo. EV miRNA cargo‑predicted targetome correlates with Gene Ontology (GO) pathways involved in …

The Therapeutic Potential Of Glycosaminoglycan Directed Metalloglycomics: Elucidating New Targets And Mechanisms For Polynuclear Platinum Complexes, James D. Hampton

Theses and Dissertations

Cancer remains a serious clinical problem and in order to continue to improve patient health outcomes, novel treatment strategies must continue to be developed. Platinum chemotherapies remain as one of the most widely successful classes of cancer therapeutic, with over 50% of cancer patients receiving a platinate at some point over the span of their treatment. However, intrinsic and extrinsic resistances limit their effectiveness, long term efficacy, and broad applicability to multiple cancer subtypes. Therefore, the development of new agents and strategies which can overcome these limitations are crucial for patient health. To this end a novel class of polynuclear …

Plasma-Treated Solutions (Pts) In Cancer Therapy, Hiromasa Tanaka, Sander Bekeschus, Dayun Yan, Masaru Hori, Michael Keidar, Mounir Laroussi

Electrical & Computer Engineering Faculty Publications

Cold physical plasma is a partially ionized gas generating various reactive oxygen and nitrogen species (ROS/RNS) simultaneously. ROS/RNS have therapeutic effects when applied to cells and tissues either directly from the plasma or via exposure to solutions that have been treated beforehand using plasma processes. This review addresses the challenges and opportunities of plasma-treated solutions (PTSs) for cancer treatment. These PTSs include plasma-treated cell culture media in experimental research as well as clinically approved solutions such as saline and Ringer’s lactate, which, in principle, already qualify for testing in therapeutic settings. Several types of cancers were found to succumb to …

Extracellular vesicles are thought to facilitate pathogen transmission from arthropods to humans and other animals. Here, we reveal that pathogen spreading from arthropods to the mammalian host is multifaceted. Extracellular vesicles from Ixodes scapularis enable tick feeding and promote infection of the mildly virulent rickettsial agent Anaplasma phagocytophilum through the SNARE proteins Vamp33 and Synaptobrevin 2 and dendritic epidermal T cells. However, extracellular vesicles from the tick Dermacentor andersoni mitigate microbial spreading caused by the lethal pathogen Francisella tularensis. Collectively, we establish that tick extracellular vesicles foster distinct outcomes of bacterial infection and assist in vector feeding by acting …

Impact Of Hemodynamic Vortex Spatial And Temporal Characteristics On Analysis Of Intracranial Aneurysms, Kevin W. Sunderland

Dissertations, Master's Theses and Master's Reports

Subarachnoid hemorrhage is a potentially devastating pathological condition in which bleeding occurs into the space surrounding the brain. One of the prominent sources of subarachnoid hemorrhage are intracranial aneurysms (IA): degenerative, irregular expansions of area(s) of the cerebral vasculature. In the event of IA rupture, the resultant subarachnoid hemorrhage ends in patient mortality occurring in ~50% of cases, with survivors enduring significant neurological damage with physical or cognitive impairment. The seriousness of IA rupture drives a degree of clinical interest in understanding these conditions that promote both the development and possible rupture of the vascular malformations. Current metrics for the …

Mitochondrial Aspects Of Neuronal Pathology In Triple-Transgenic Alzheimer’S Disease Mice, John Zachary Cavendish

Graduate Theses, Dissertations, and Problem Reports (ETD)

Alzheimer’s disease (AD) is a fatal, progressive neurodegenerative disease afflicting millions of people in the United States alone and is the only one of the top leading causes of morbidity and mortality with no effective disease-modifying therapies. It is the most common form of dementia, affecting one in three people over the age of 85. While the hallmarks of the disease include accumulation of beta-amyloid-based extracellular plaques and hyperphosphorylated tau-based intracellular neurofibrillary tangles, treatment strategies centered on removing or mitigating these components of AD have all failed in humans. Mitochondrial dysfunction has been increasingly recognized as an early and consistent …

Epidemiology Of Non-Alcoholic Fatty Liver Disease And Risk Of Hepatocellular Carcinoma Progression, Krishna Chaitanya Thandra, Adam Barsouk, Kalyan Saginala, John Sukumar Aluru, Prashanth Rawla, Alexander Barsouk

Kimmel Cancer Center Faculty Papers

Non-alcoholic fatty liver disease (NAFLD) has become the most common chronic liver disease worldwide. Its incidence has grown alongside the increasing global prevalence of type 2 diabetes, obesity, and metabolic syndrome. The risk of progression to hepatocellular carcinoma for nonalcoholic steatohepatitis patients over 5 years is 8%, and despite targeted and immunotherapy treatment advances, HCC maintains a bleak 5-year survival of 19%. NAFLD’s primary risk factors are components of metabolic syndrome as well as possible sleep disturbances. NAFLD is most common among men 50-60 years of age, though incidence in women catches up after menopause. In the US, Hispanics are …

Mechanisms By Which Mnte-2-Pyp Suppresses Prostate Cancer Cell Growth, Yuxiang Zhu

Theses & Dissertations

Prostate cancer patients are often treated with radiotherapy. MnTE-2-PyP, is a superoxide dismutase (SOD) mimic and a known radioprotector of normal tissues. Our recent work demonstrates that MnTE-2-PyP also inhibits prostate cancer progression with radiotherapy; however, the mechanisms remain unclear. In this thesis, we identified that MnTE-2-PyP-induced intracellular H2O2 levels are critical in inhibiting growth of prostate cancer cells. We found that MnTE-2-PyP induced protein oxidations in PC3 cells and one major group of oxidized protein targets were involved in energy metabolism. The oxidative phosphorylation rates were significantly enhanced in both PC3 and LNCaP cells with MnTE-2-PyP treatment, but mitochondrial …

Faculty Research, Scholarly, and Creative Activity

Malnutrition is highly prevalent in patients with foregut tumors comprising head and neck (HNC) and esophageal (EC) cancers, negatively impacting outcomes. International evidence-based guidelines (EBGs) for nutrition care exist; however, translation of research evidence into practice commonly presents considerable challenges and consequently lags. This study aimed to describe and evaluate current international nutrition care practices compared with the best-available evidence for patients with foregut tumors who are at high risk of malnutrition. A multi-centre prospective cohort study enrolled 170 patients commencing treatment of curative intent for HNC (n = 119) or EC (n = 51) in 11 cancer …

Structural Characterization And In Vitro Lipid Binding Studies Of Non-Specific Lipid Transfer Protein 1 (Nsltp1) From Fennel (Foeniculum Vulgare) Seeds, Mekdes Megeressa, Bushra Siraj, Shamshad Zarina, Aftab Ahmed

Pharmacy Faculty Articles and Research

Non-specific lipid transfer proteins (nsLTPs) are cationic proteins involved in intracellular lipid shuttling in growth and reproduction, as well as in defense against pathogenic microbes. Even though the primary and spatial structures of some nsLTPs from different plants indicate their similar features, they exhibit distinct lipid-binding specificities signifying their various biological roles that dictate further structural study. The present study determined the complete amino acid sequence, in silico 3D structure modeling, and the antiproliferative activity of nsLTP1 from fennel (Foeniculum vulgare) seeds. Fennel is a member of the family Umbelliferae (Apiaceae) native to southern Europe and the Mediterranean …

Technology Aiding In Neonatal Lung Developmental Care, Megan Kirk

Undergraduate Honors Theses

In this paper, old as well as new technological findings to decrease premature infant mortality are reviewed. This paper discusses fetal development throughout pregnancy from conception to full-term status as well as fetal lung development specifically from conception until full-term status. Several ideas to rapidly develop and mature fetal lungs are discussed such as mothers ingesting artificial surfactant supplements, either independently or coupled with antenatal corticosteroids, as well as intra-amniotic instillation prior to 28 weeks gestational. Drawbacks regarding these two are mentioned as well such as the fetus’s lungs not being mature enough to use the artificial surfactant leading into …

Role Of Β-Glucan Structure In Dectin-1 Homo- And Hetero-Oligomerization In Innate Anti-Fungal Immunity, Eduardo U. Anaya

Biomedical Sciences ETDs

Dectin-1A is a C-type Lectin innate immunoreceptor that recognizes β-(1,3)-glucan, a structural component of Candida species cell walls. Dectin-1 has eight alternative splice isoforms including, A and B. Innate immunocytes can express one or both isoforms, but neither their relative responsiveness to β-glucan nor the potential for inter-isoform signaling cross-talk is well understood. In this study, we determine how the different structures of soluble β-glucans affect both isoforms and unravel how differences in glucan structure impact the earliest events in Dectin-1 signaling. Using quantitative microscopy techniques, we explored the role of glucan structure on Dectin-1A oligomerization, which is thought to …

Disruption Of Dna Polymerase Zeta Promotes An Innate Immune Response, Sara Martin

Dissertations and Theses (Open Access)

DNA polymerase ζ (pol ζ) is a specialized polymerase that protects cells from the consequences of DNA damage and stress. Without pol ζ function mammalian cells and yeast are exquisitely sensitive to genotoxic stresses including ultraviolet irradiation and platinum compounds such as the chemotherapeutic agent cisplatin. This elevated sensitivity arises from the central role of pol ζ in lesion bypass. Pol ζ is also required to protect cells from endogenous genomic damage or stress. In primary mammalian cells, the function of pol ζ is required for genome protection and normal proliferation. Immortalized Rev3lknockout (KO) MEFs are under considerable constitutive …

A Functional Three-Dimensional Microphysiological Model Of Myeloma Bone Disease, Richard Visconti

Seton Hall University Dissertations and Theses (ETDs)

Multiple myeloma (MM) is a hematologic cancer caused by a mature B cell neoplasm, or plasmacytoma, that infiltrates the skeleton at several sites. The disease is characterized by uninhibited transformed plasma cell proliferation that disrupts skeletal homeostasis leading to decreased bone modeling and increased bone resorption. Osteolytic lesions (OL) or voids left in the bone, remain long after the treatment of the cancer and indicate disease progression to myeloma bone disease (MBD). Current combinatorial MM therapies inhibit malignant plasma cell proliferation, slow the progression towards MBD, and increase the mean five-year survival rate, but do little to improve osteoblastic function …

Subclonal evolution of chronic lymphocytic leukemia after allogeneic T-cell therapies

Haven Garber, MD

Advisory Professor: Jeffrey Molldrem, MD

Intratumoral genetic heterogeneity describes the molecular differences among subclones within a tumor and is a major barrier to effective therapy in many solid and liquid cancers, including chronic lymphocytic leukemia (CLL). Rare, treatment-resistant subclones can expand to compose relapsed disease during tumor evolution. Examination of malignant evolution in the context of specific treatment provides insight into the molecular lesions that mediate therapeutic response and resistance. Both chemotherapy and targeted therapy were shown to precipitate CLL subclonal evolution. We hypothesized that allogeneic T-cell …

P53 Drives A Transcriptional Program That Elicits A Non-Cell-Autonomous Response And Alters Cell State In Vivo, Sydney Moyer

Dissertations and Theses (Open Access)

Cell stress and DNA damage activate the tumor suppressor p53, triggering transcriptional activation of a myriad of target genes. The molecular, morphological, and physiological consequences of this activation remain poorly understood in vivo. We activated a p53 transcriptional program in mice by deletion of Mdm2, a gene which encodes the major p53 inhibitor. By overlaying tissue-specific RNA-sequencing data from pancreas, small intestine, ovary, kidney, and heart with existing p53 ChIP-sequencing, we identified a large repertoire of tissue-specific p53 genes and a common p53 transcriptional signature of seven genes which included Mdm2 but not p21. Global p53 activation …

Sine Oculis Homeobox Homolog 1 (Six1) Plays A Critical Role In The Progression Of Pulmonary Fibrosis., Cory Wilson

Dissertations and Theses (Open Access)

Idiopathic pulmonary fibrosis (IPF) is the most common idiopathic interstitial pneumonia with a median survival time of 2-4 years after diagnosis. The alarming mortality rate is due to the lack of effective treatments. IPF is a chronic disease that is characterized by alveolar destruction due to increasing extracellular matrix deposition that leads to poor lung compliance, impaired gas exchange, and ultimately respiratory failure. Repetitive alveolar epithelial injury is a central process to the underlying pathology with injury to the type II alveolar epithelial cells (AT2) specifically being a key player in the pathogenesis of IPF. Recent studies have shown that …

The Role Of Daam1 In Kidney Development, Vanja Krneta-Stankic

Dissertations and Theses (Open Access)

Kidneys, like most organs in our bodies, consist of a network of epithelial tubules. Kidney tubules are called nephrons, and their morphology is important for kidney function. Nephrons develop from mesodermally derived aggregates of progenitor cells. The nephric progenitors organize into nephric tubules lined with hair-like sensory projections called cilia. Many diseases of the kidney are characterized by abnormal nephron morphology with current treatment aimed at symptom control. To understand the mechanisms underlying kidney diseases and achieve the development of novel therapies, a better understanding of how nephrons develop is needed. Although the actin cytoskeleton is critical for cell behaviors …

Packaging And Secretion Of Airway Mucins, Oanh Ngoc Hoang

Dissertations and Theses (Open Access)

In the conducting airways of the lungs, the mobile mucus gel layer sits on top of the airway epithelium, and through ciliary beating it is propelled up the trachea into the pharynx where it is swallowed and cleared. This gel layer is composed of secreted mucins that become hydrated once reaching the airway lumen. Mucins are secreted at a baseline rate and at a stimulated rate, dependent on the amount of agonist. Baseline secretion is responsible for steady clearance of inhaled particles and pathogens. Stimulated secretion is thought to play a role in trapping helminths though mucus occlusion in small …

Qki-Mediated Cholesterol Biosynthesis In Eye Lens And Myelin Of The Central Nervous System, Seula Shin, Seula Shin

Dissertations and Theses (Open Access)

Cells obtain cholesterol in two ways, de novo biosynthesis and uptake from circulation. While most tissues utilize both sources, eye lens and brain depend extensively on cholesterol biosynthesis due to the limited supply from circulation. Lens cell membrane consists of highest portion of cholesterol. Brain is the most cholesterol-rich organ, which accounts for 23% of total cholesterol. Genetic mutations of cholesterol biosynthesis enzymes in humans and animal models present cataracts and hypomyelinating disorders linked to neurological impairment. Yet, it remains unclear how gene expression of cholesterol biosynthesis is regulated in lens and brain. Therefore, studying cholesterol biosynthesis in both tissues …

Fibroblast Heterogeneity In Pancreatic Cancer Immunity, Josephine Darpolor

Dissertations and Theses (Open Access)

Fibroblasts are a unique cell type defined by their mesenchymal phenotype and exclusion from epithelial, immune, and endothelial cell subsets. Although well studied in wound healing, cancer associated fibroblasts (CAFs) are incredibly heterogeneous, leading to contradictions as to the roles CAFs play in the tumor microenvironment (TME). CAFs were thought to be a barrier to treatment of pancreatic ductal adenocarcinoma (PDAC). However, general stromal targeting strategies have largely failed in the clinic likely due to the heterogeneity of CAFs in the TME. Therefore, our groups and others have worked to unravel the heterogeneity of CAFs in PDAC. In the works …

Corticotropin-Releasing Factor Infusion In The Bed Nucleus Of The Stria Terminalis Of Lactating Mice Alters Maternal Care And Induces Behavioural Phenotypes In Offspring, Kerstin Camile Creutzberg, Érika Kestering-Ferreira, Thiago Wendt Viola, Luis Eduardo Wearick-Silva, Rodrigo Orso, Bernardo Aguzzoli Heberle, Lucas Albrechet-Souza, Rosa Maria Martins De Almeida, Rodrigo Grassi-Oliveira

School of Medicine Faculty Publications

The peripartum period is accompanied by numerous physiological and behavioural adaptations organised by the maternal brain. These changes are essential for adequate expression of maternal behaviour, thereby ensuring proper development of the offspring. The corticotropin-releasing factor (CRF) plays a key role in a variety of behaviours accompanying stress, anxiety, and depression. There is also evidence that CRF contributes to maladaptations during the peripartum period. We investigated the effects of CRF in the bed nucleus of the stria terminalis (BNST) of lactating mice during maternal care and analysed locomotor activity and anxiety-like behaviour in the offspring. The BNST has been implicated …
