Cis-Regulatory Mechanisms Through Stages Of Erythroid Regenration, Yichao Zhou

Theses & Dissertations

Produced by steady state erythropoiesis, erythrocytes serve as vital regulators of metabolism and life by delivering oxygen to all the cells and tissues. Under acute anemia, steady state erythropoiesis is not sufficient to produce enough erythrocytes, leading to distinct mechanisms needed to regenerate large numbers of mature erythrocytes rapidly. Erythroid regeneration occurs in four stages: activation, expansion and differentiation, resolution, and post-resolution, according to the dynamics of erythrocyte numbers and progenitor activity. Erythroid regeneration throughout this timeline requires some critical extracellular cues, but the intrinsic molecular mechanisms needed to accelerate and decelerate the activity of erythroid progenitors in anemia and …

Promoting Physiologic Birth By Improving Access To Doulas, Karen Schwartz

Doctor of Nursing Practice (DNP) Translational and Clinical Research Projects

Birth in the United States (U.S.) leans towards a medicalized approach, overlooking the advantages of physiologic birth. Physiologic birth is a natural approach to childbirth, without medical interventions. Intrapartum nurses play an integral role in caring for women during labor by providing continuous labor support. Competing nursing tasks, exacerbated nursing shortages and increased nurse to patient ratios have made it increasingly challenging for intrapartum (IP) nurses to provide continuous labor support to their patients. The aim of this DNP project is to gain insight into the beliefs of IP nurses regarding childbirth and how these beliefs impact their approach to …

AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid) receptors (AMPARs) mediate fast excitatory neurotransmission in the brain. AMPARs form by homo- or heteromeric assembly of subunits encoded by the GRIA1–GRIA4 genes, of which only GRIA3 is X-chromosomal. Increasing numbers of GRIA3 missense variants are reported in patients with neurodevelopmental disorders (NDD), but only a few have been examined functionally.

Here, we evaluated the impact on AMPAR function of one frameshift and 43 rare missense GRIA3 variants identified in patients with NDD by electrophysiological assays. Thirty-one variants alter receptor function and show loss-of-function or gain-of-function properties, whereas 13 appeared neutral.

We collected detailed …

Background: Glioblastomas (GBMs) are central nervous system tumors that resist standard-of-care interventions and even immune checkpoint blockade. Myeloid cells in the tumor microenvironment can contribute to GBM progression; therefore, emerging immunotherapeutic approaches include reprogramming these cells to achieve desirable antitumor activity. Triggering receptor expressed on myeloid cells 2 (TREM2) is a myeloid signaling regulator that has been implicated in a variety of cancers and neurological diseases with contrasting functions, but its role in GBM immunopathology and progression is still under investigation.

Methods: Our reverse translational investigations leveraged single-cell RNA sequencing and cytometry of human gliomas to characterize TREM2 expression across …

Rashes are one of the most common chief complaints we see as emergency medicine physicians on a day-to-day basis. Most of them tend to be self-limited and require very little workup and can be discharged home; however, it is our job to try to identify rashes that may require isolation in order to prevent an outbreak in our communities. Here we present a case of one such rash that has gained major media attention as of late, Monkeypox.

The Effect Of Covid-19 Pandemic On Sanitation Practices And Anxiety In The General Population, Leah Cliatt, Joanna Petrides

Rowan-Virtua Research Day

Background: Illness anxiety and fear of contracting coronavirus increased considerably during the COVID-19 pandemic. The media, being in lockdown, and cyberchondria had the largest impact on the population’s anxiety surrounding illness. While this kind of reaction to illness is expected during the pandemic, there is limited data on post-pandemic illness anxiety levels in the general population. Patients’ perception of disease impacts medicine at every level; medical professionals need to understand the concerns and fears of their patients in order to treat the post-pandemic patient. We hypothesized that sanitation practices and anxiety surrounding illness have not returned to baseline pre-COVID-19 …

Waiting For A Cure: Factors Influencing Melanoma Treatment Delays, Lisa Huang, David Rubin, Lothar Vidal, Jordan Riser, Christopher Jones, Samantha Hiester

Rowan-Virtua Research Day

Melanoma, with a five-year survival rate of 94% in early-stage diagnosis, drops significantly when diagnosed at later stages, making identifying barriers to timely treatment crucial. This literature review examines factors influencing melanoma treatment wait times and their impact on patient outcomes. Elderly, male, and Medicare patients, along with those with higher Breslow thickness and severe melanoma stages, experienced longer wait times. Patients receiving intervention within 30 days had better survival rates. Lack of knowledge and misconceptions about melanoma contribute to delayed care, particularly in communities with lower incidence rates. Black patients faced longer waits from diagnosis to surgery, indicating disparities. …

Evaluation Of The Efficacy Of Novel Drugs And Combinations Against Extensively- And Pan-Drug Resistant Acinetobacter Baumannii Isolates, Keertana Jonnalagadda, Rachel Carr, Valerie Carabetta

Rowan-Virtua Research Day

Acinetobacter baumannii, a Gram-negative, nosocomial, opportunistic pathogen is commonly infectious in immunocompromised patients. More specifically patients develop healthcare-associated infections (HAI) spanning beyond sepsis, pneumonia, meningitis, and urinary tract infections. Due to its rapid ability to acquire antibiotic resistance, it has raised the necessity to discern a novel therapeutic treatment that can be effectively used against the multidrug resistant (MDR) A. baumannii. Cooper University Hospital (CUH) faced an increased case load of patients that were infected with MDR A. baumannii. The patient isolates obtained from CUH were highly resistant to the 22 standard-of-care antibiotics. With the recent introduction …

Tools for genome-wide rapid identification of peptide-major histocompatibility complex targets of T-cell receptors (TCR) are not yet universally available. We present a new antigen screening method, the T-synapse (Tsyn) reporter system, which includes antigen-presenting cells (APC) with a Fas-inducible NF-κB reporter and T cells with a nuclear factor of activated T cells (NFAT) reporter. To functionally screen for target antigens from a cDNA library, productively interacting T cell-APC aggregates were detected by dual-reporter activity and enriched by flow sorting followed by antigen identification quantified by deep sequencing (Tsyn-seq). When applied to a previously characterized TCR specific for the E7 antigen …

De Novo Genome Assembly For The Coppery Titi Monkey (Plecturocebus Cupreus): An Emerging Nonhuman Primate Model For Behavioral Research, Susanne P Pfeifer, Alexander Baxter, Logan E Savidge, Fritz J Sedlazeck, Karen L Bales

Faculty, Staff and Students Publications

The coppery titi monkey (Plecturocebus cupreus) is an emerging nonhuman primate model system for behavioral and neurobiological research. At the same time, the almost entire absence of genomic resources for the species has hampered insights into the genetic underpinnings of the phenotypic traits of interest. To facilitate future genotype-to-phenotype studies, we here present a high-quality, fully annotated de novo genome assembly for the species with chromosome-length scaffolds spanning the autosomes and chromosome X (scaffold N50 = 130.8 Mb), constructed using data obtained from several orthologous short- and long-read sequencing and scaffolding techniques. With a base-level accuracy of ∼99.99% in chromosome-length …

eEF2 post-translational modifications (PTMs) can profoundly affect mRNA translation dynamics. However, the physiologic function of eEF2K525 trimethylation (eEF2K525me3), a PTM catalyzed by the enzyme FAM86A, is unknown. Here, we find that FAM86A methylation of eEF2 regulates nascent elongation to promote protein synthesis and lung adenocarcinoma (LUAD) pathogenesis. The principal physiologic substrate of FAM86A is eEF2, with K525me3 modeled to facilitate productive eEF2-ribosome engagement during translocation. FAM86A depletion in LUAD cells causes 80S monosome accumulation and mRNA translation inhibition. FAM86A is overexpressed in LUAD and eEF2K525me3 levels increase through advancing LUAD disease stages. FAM86A knockdown attenuates LUAD cell proliferation and suppression …

Optimization, Characterization, And Comparison Of Two Luciferase-Expressing Mouse Glioblastoma Models, Louis Rodgers, Julia A. Schulz Pauly, Bryan J. Maloney, Anika M. S. Hartz, Bjoern Bauer

UK CARES Faculty Publications

Glioblastoma (GBM) is the most aggressive brain cancer. To model GBM in research, orthotopic brain tumor models, including syngeneic models like GL261 and genetically engineered mouse models like TRP, are used. In longitudinal studies, tumor growth and the treatment response are typically tracked with in vivo imaging, including bioluminescence imaging (BLI), which is quick, cost-effective, and easily quantifiable. However, BLI requires luciferase-tagged cells, and recent studies indicate that the luciferase gene can elicit an immune response, leading to tumor rejection and experimental variation. We sought to optimize the engraftment of two luciferase-expressing GBM models, GL261 Red-FLuc and TRP-mCherry-FLuc, showing differences …

RNA viruses, like SARS-CoV-2, depend on their RNA-dependent RNA polymerases (RdRp) for replication, which is error-prone. Monitoring replication errors is crucial for understanding the virus’s evolution. Current methods lack the precision to detect rare de novo RNA mutations, particularly in low-input samples such as those from patients. Here, we introduce a new targeted Accurate RNA Consensus sequencing method (tARC-seq) to accurately determine the mutation frequency and types in SARS-CoV-2, both in cell culture and clinical samples. Our findings show an average of 2.68×10−5 new errors per cycle with a C>T bias that cannot be solely attributed to APOBEC …
