Topographical Distribution And Morphology Of Sympathetic Postganglionic Innervation And Chronic Intermittent Hypoxia (Cih) Induced Remodeling Of The Whole Heart At Single Cell/Axon/Varicosity Scale, Ariege Bizanti

Electronic Theses and Dissertations, 2020-2023

The sympathetic nervous system is crucial for controlling multiple cardiac functions and its overactivity is associated with many cardiovascular diseases (CVD). Chronic intermittent hypoxia (CIH) is a current model for sleep apnea, which constitutes a major risk factor for CVD through sympathetic overactivity. However, a comprehensive neuroanatomical map of the sympathetic innervation of the heart is unavailable which impedes our understanding of the remodeling of this map in pathological conditions. First, we used a combination of state-of-the-art techniques, including flat-mount tissue processing, immunohistochemistry for tyrosine hydroxylase (TH, a sympathetic marker), confocal microscopy and Neurolucida 360 software to trace, digitize, and …

There have been conflicting data regarding liver transplantation (LT) outcomes for hereditary hemochromatosis (HH), with no recent data on LT outcomes in patients with HH in the past decade. Using the United Network for Organ Sharing registry, we evaluated waitlist and post-LT survival in all adult patients listed for HH without concomitant liver disease from 2003 to 2019. Post-LT survival for HH was compared with a propensity-matched (recipient and donor factors) cohort of recipients with chronic liver disease (CLD). From 2003 to 2019, 862 patients with HH were listed for LT, of which 55.6% ( n = 479) patients underwent …

Implications Of The Paradigm Shift In Management Of Helicobacter Pylori Infections, David Y Graham

Faculty, Staff and Students Publications

The recent availability of susceptibility testing for Helicobacter pylori infections in the United Sates has resulted in paradigm shifts in the diagnosis, therapy, and follow-up of H. pylori infections. Here, we reviewed the English literature concerning changes in H. pylori diagnosis and therapy with an emphasis on the last 3 years. We focus on the new methods that offer rapid and convenient susceptibility testing using either invasive (endoscopic) or noninvasive (stool) methods of obtaining test material. We also discuss the implications of this availability on therapy and follow-up after therapy. The approach to therapy was categorized into four groups: (1) …

How Widespread And Convenient H Pylori Susceptibility Testing Will Result In Pharmacological Opportunities, Theodore Rokkas, David Y Graham

Faculty, Staff and Students Publications

Introduction:

Until recently antimicrobial therapy for Helicobacter pylori infections was almost universally empirical and based on a combination of expert opinion and local effectiveness. However, the average cure rates rarely achieved more than 80%. The new requirement that all therapeutic regimens reliably achieve high cure rates, the introduction of potassium competitive acid blockers and the availability of susceptibility testing many pharmacological opportunities particularly since all current therapies will require optimization. The ability to rapidly and inexpensively obtain H. pylori susceptibility data using stool samples makes obtaining susceptibility data practical and allows using susceptibility-based therapy routinely for both treatment naïve patient …

The Coordinated Management Of Ribosome And Translation During Injury And Regeneration, Thanh Nguyen, Jason C Mills, Charles J Cho

Faculty, Staff and Students Publications

Diverse acute and chronic injuries induce damage responses in the gastrointestinal (GI) system, and numerous cell types in the gastrointestinal tract demonstrate remarkable resilience, adaptability, and regenerative capacity in response to stress. Metaplasias, such as columnar and secretory cell metaplasia, are well-known adaptations that these cells make, the majority of which are epidemiologically associated with an elevated cancer risk. On a number of fronts, it is now being investigated how cells respond to injury at the tissue level, where diverse cell types that differ in proliferation capacity and differentiation state cooperate and compete with one another to participate in regeneration. …

Shared Features Of Metaplasia And The Development Of Adenocarcinoma In The Stomach And Esophagus, Yongji Zeng, Qing K Li, Sujayita Roy, Jason C Mills, Ramon U Jin

Faculty, Staff and Students Publications

Introduction: Plasticity is an inherent property of the normal gastrointestinal tract allowing for appropriate response to injury and healing. However, the aberrancy of adaptable responses is also beginning to be recognized as a driver during cancer development and progression. Gastric and esophageal malignancies remain leading causes of cancer-related death globally as there are limited early disease diagnostic tools and paucity of new effective treatments. Gastric and esophageal adenocarcinomas share intestinal metaplasia as a key precancerous precursor lesion.

Methods: Here, we utilize an upper GI tract patient-derived tissue microarray that encompasses the sequential development of cancer from normal tissues to illustrate …

Sox9 Governs Gastric Mucous Neck Cell Identity And Is Required For Injury-Induced Metaplasia, Spencer G Willet, Nattapon Thanintorn, Helen Mcneill, Sung-Ho Huh, David M Ornitz, Won Jae Huh, Stella G Hoft, Richard J Dipaolo, Jason C Mills

Faculty, Staff and Students Publications

BACKGROUND & AIMS: Acute and chronic gastric injury induces alterations in differentiation within the corpus of the stomach called pyloric metaplasia. Pyloric metaplasia is characterized by the death of parietal cells and reprogramming of mitotically quiescent zymogenic chief cells into proliferative, mucin-rich spasmolytic polypeptide-expressing metaplasia (SPEM) cells. Overall, pyloric metaplastic units show increased proliferation and specific expansion of mucous lineages, both by proliferation of normal mucous neck cells and recruitment of SPEM cells. Here, we identify Sox9 as a potential gene of interest in the regulation of mucous neck and SPEM cell identity in the stomach.

METHODS: We used immunostaining …

Cardiovascular Hemodynamics In Mice With Tumor Necrosis Factor Receptor-Associated Factor 2 Mediated Cytoprotection In The Heart, Andrea G Marshall, Kit Neikirk, Zer Vue, Heather K Beasley, Edgar Garza-Lopez, Larry Vang, Taylor Barongan, Zoe Evans, Amber Crabtree, Elsie Spencer, Josephs Anudokem, Remi Parker, Jamaine Davis, Dominique Stephens, Steven Damo, Thuy T Pham, Jose A Gomez, Vernat Exil, Dao-Fu Dai, Sandra A Murray, Mark L Entman, George E Taffet, Antentor O Hinton, Anilkumar K Reddy

Faculty, Staff and Students Publications

INTRODUCTION: Many studies in mice have demonstrated that cardiac-specific innate immune signaling pathways can be reprogrammed to modulate inflammation in response to myocardial injury and improve outcomes. While the echocardiography standard parameters of left ventricular (LV) ejection fraction, fractional shortening, end-diastolic diameter, and others are used to assess cardiac function, their dependency on loading conditions somewhat limits their utility in completely reflecting the contractile function and global cardiovascular efficiency of the heart. A true measure of global cardiovascular efficiency should include the interaction between the ventricle and the aorta (ventricular-vascular coupling, VVC) as well as measures of aortic impedance and …

Novel Banana Lectin Car-T Cells To Target Pancreatic Tumors And Tumor-Associated Stroma, Mary K Mckenna, Ada Ozcan, Daniel Brenner, Norihiro Watanabe, Maureen Legendre, Dafydd G Thomas, Christopher Ashwood, Richard D Cummings, Challice Bonifant, David M Markovitz, Malcolm K Brenner

Faculty, Staff and Students Publications

BACKGROUND: Cell therapies for solid tumors are thwarted by the hostile tumor microenvironment (TME) and by heterogeneous expression of tumor target antigens. We address both limitations with a novel class of chimeric antigen receptors based on plant lectins, which recognize the aberrant sugar residues that are a 'hallmark' of both malignant and associated stromal cells. We have expressed in T cells a modified lectin from banana, H84T BanLec, attached to a chimeric antigen receptor (H84T-CAR) that recognizes high-mannose (asparagine residue with five to nine mannoses). Here, we tested the efficacy of our novel H84T CAR in models of pancreatic ductal …

Faculty, Staff and Students Publications

INTRODUCTION: Endometriosis, a benign inflammatory disease whereby endometrial-like tissue grows outside the uterus, is a risk factor for endometriosis-associated ovarian cancers. In particular, ovarian endometriomas, cystic lesions of deeply invasive endometriosis, are considered the precursor lesion for ovarian clear-cell carcinoma (OCCC).

METHODS: To explore this transcriptomic landscape, OCCC from women with pathology-proven concurrent endometriosis (n = 4) were compared to benign endometriomas (n = 4) by bulk RNA and small-RNA sequencing.

RESULTS: Analysis of protein-coding genes identified 2449 upregulated and 3131 downregulated protein-coding genes (DESeq2, P< 0.05, log2 fold-change > |1|) in OCCC with concurrent endometriosis compared to endometriomas. Gene set enrichment …

The prognosis of relapsed/refractory (R/R) anaplastic large cell lymphoma (ALCL) is poor. Large studies evaluating outcomes of allogeneic haematopoietic cell transplantation (allo-HCT) in systemic R/R ALCL are not available. Using the Center for International Blood and Marrow Transplant Research (CIBMTR) database, we evaluated outcomes of 182 adults (aged ≥18 years) with R/R ALCL undergoing allo-HCT between 2008 and 2019. Non-relapse mortality (NRM), disease relapse/progression (REL), progression-free survival (PFS), and overall survival (OS) were modelled using Cox proportional hazards models. The median (range) follow-up of survivors was 62 (3-148) months. The 1-year NRM was 18%. The 5-year REL, PFS and OS …

Emerging Challenges To Cellular Therapy Of Cancer, Premal D Lulla, Malcolm Brenner

Faculty, Staff and Students Publications

Cellular immunotherapy of cancer in the form of chimeric antigen receptor-modified T-cell therapy has become a standard treatment for lymphoid and more recently plasma cell malignancies. Although their successes in these cancers represent a breakthrough for adoptive cell therapy, there are several challenges to their continued growth in the field of cancer medicine. In this review, we discuss the progress made thus far toward achieving "off-the-shelf" accessibility of cell therapies that has the potential to greatly offset the costs associated with the current practice of making patient-specific products. We also review the innovations under investigation that attempt to make cellular …

Faculty, Staff and Students Publications

As the COVID-19 pandemic continues into its third year, emerging data indicates increased risks associated with SARS-CoV-2 infection during pregnancy, including pre-eclampsia, intrauterine growth restriction, preterm birth, stillbirth, and risk of developmental defects in neonates. Here, we review clinical reports to date that address different COVID-19 pregnancy complications. We also document placental pathologies induced by SARS-CoV-2 infection, entry mechanisms in placental cells, and immune responses at the maternal-fetal interface. Since new variants of SARS-CoV-2 are emerging with characteristics of higher transmissibility and more effective immune escape strategies, we also briefly highlight the genomic and proteomic features of SARS-CoV-2 investigated to …

Alveolar Macrophages In Lung Cancer: Opportunities Challenges, Cheng-Yen Chang, Dominique Armstrong, David B Corry, Farrah Kheradmand

Faculty, Staff and Students Publications

Alveolar macrophages (AMs) are critical components of the innate defense mechanism in the lung. Nestled tightly within the alveoli, AMs, derived from the yolk-sac or bone marrow, can phagocytose foreign particles, defend the host against pathogens, recycle surfactant, and promptly respond to inhaled noxious stimuli. The behavior of AMs is tightly dependent on the environmental cues whereby infection, chronic inflammation, and associated metabolic changes can repolarize their effector functions in the lungs. Several factors within the tumor microenvironment can re-educate AMs, resulting in tumor growth, and reducing immune checkpoint inhibitors (ICIs) efficacy in patients treated for non-small cell lung cancer …

Faculty, Staff and Students Publications

INTRODUCTION: As people age with HIV (PWH), many comorbid diseases are more common than among age matched comparators without HIV (PWoH). While the Veterans Aging Cohort (VACS) Index 2.0 accurately predicts mortality in PWH using age and clinical biomarkers, the only included comorbidity is hepatitis C. We asked whether adding comorbid disease groupings from the Charlson Comorbidity Index (CCI) improves the accuracy of VACS Index.

METHODS: To maximize our ability to model mortality among older age groups, we began with PWoH in Veterans Health Administration (VA) from 2007-2017, divided into development and validation samples. Baseline predictors included age, and components …

Clinical Approach To Evaluation Of Underlying Cardiac Device Infection In Patients Hospitalized With Bacteremia, Dierdre B Axell-House, Sarwat Khalil, M Rizwan Sohail

Faculty, Staff and Students Publications

More than 400,000 cardiac implantable electronic devices (CIEDs), including permanent pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy devices, are implanted every year in the United States (US). Infection is a serious complication of CIED therapy and is associated with high morbidity and mortality. While CIED pocket infection can be diagnosed based on clinical exam findings, positive blood culture may be the only manifestation of CIED lead infection. Thus, management of bacteremia in patients living with CIEDs requires special consideration. This review summarizes contemporary data in the context of the recently updated 2023 Duke-International Society for Cardiovascular Infectious Diseases Criteria for …

Bacteriuria In Older Adults Triggers Confusion In Healthcare Providers: A Mindful Pause To Treat The Worry, Eva M Amenta, Robin L P Jump, Barbara W Trautner

Faculty, Staff and Students Publications

The evidence base for refraining from screening for or treating asymptomatic bacteriuria (ASB) in older adults is strong, but both practices remain prevalent. Clinical confusion over how to respond to a change from baseline, when to order a urinalysis and urine culture, and what to do with a positive urine culture fuels unnecessary antibiotic use for ASB. If the provider can take a mindful pause to apply evidenced-based assessment tools, the resulting increased clarity in how to manage the situation can reduce overtreatment of ASB.

Gestational Vulnerability To Ozone Air Pollution - A Placental Story, Vishnupriya Alavala, Sarah Brent, Russell Hunter, Matthew J. Campen, Andrew Ottens

UROP Posters

About 99% of the global population resides in areas with air pollution surpassing World Health Organization standards. Air pollution is associated with adverse neonatal health outcomes such as low fetal birth weight and an increased risk for maternal pre-eclampsia. A particularly reactive air pollutant is ozone, which forms reactive oxygen species that induce cellular damage. Research exists on the dispersion of reactive oxygen species through the bloodstream leading to fetal vulnerability during pregnancy, specifically via the placenta. Yet, placental and fetal development is a temporal process with varied susceptibility to negative gestational outcomes.

To addressing this gap, our laboratory utilized …

Proposing An Rna Interference (Rnai)-Based Treatment For Human Immunodeficiency Virus (Hiv) By Analyzing The Post-Transcriptional Gene Targeting Of Sars-Cov-2, Hepatitis C Virus, And A549 Lung Cancer Cells, Arjun Jagdeesh

UROP Posters

Human Immunodeficiency Virus (HIV) is a retrovirus that infects CD4+ T cell lymphocytes in humans, leading to the development of Acquired Immunodeficiency Syndrome (AIDS) if left untreated. While current treatment methods, including antiretroviral combination treatments, effectively limit HIV replication, HIV can evade these treatments due to its high mutation rate. Long-term antiretroviral treatment can also be toxic to patients, meaning patients would benefit from a new mechanism of HIV treatment. RNA interference (RNAi) is an antiviral pathway found in mammals, plants, and insects that involves a small-interfering RNA that is incorporated into a protein complex called the RNA-induced Silencing Complex …

Research outputs 2022 to 2026

Externalizing traits have been related with the outcomes of coronavirus disease 2019 (COVID-19) and Alzheimer's dementia (AD); however, whether these associations are causal remains unknown. We used the two-sample Mendelian randomization (MR) approach with more than 200 single-nucleotide polymorphisms (SNPs) for externalizing traits to explore the causal associations of externalizing traits with the risk of COVID-19 (infected COVID-19, hospitalized COVID-19, and severe COVID-19) or AD based on the summary data. The inverse variance–weighted method (IVW) was used to estimate the main effect, followed by several sensitivity analyses. IVW analysis showed significant associations of externalizing traits with COVID-19 infection (odds ratio …

Dysfunction of the cholinergic basal forebrain (BF) system and amyloid- (A ) deposition are early pathological features in Alzheimer's disease (AD). However, their association in early AD is not well-established. This study investigated the nature and magnitude of volume loss in the BF, over an extended period, in 516 older adults who completed A -PET and serial magnetic resonance imaging scans. Individuals were grouped at baseline according to the presence of cognitive impairment (CU, CI) and A status (A −, A +). Longitudinal volumetric changes in the BF and hippocampus were assessed across groups. The results indicated that high A …

Sheprep: Examining The Influence Of The Messaging And The Messenger Associated With Prep Uptake Among African American Women, Christian C. Spears

College of Graduate Studies: Theses & Dissertations

African American Women (AAW) make up less than 15% of the female population in the United States but account for over 50% of new HIV diagnoses among females. This largely preventable health disparity can be mitigated by advocating and prescribing Pre-exposure Prophylaxis (PrEP), a preventive HIV medication, to persons at risk. Despite advances in medication options, there are less than 13% of Black people who could benefit from having been prescribed PrEP, and limited research and promotion on the effectiveness of PrEP for AAW. The “ShePrEP Study” aimed to assess awareness, perceptions, and receptivity toward PrEP among AAW. This study …

Heat Shock Protein 90 (Hsp90) System In Health And Disease., Daniella Munezero

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cells rely on heat shock proteins (HSP) to facilitate and regulate the folding of the substrate proteins into their native state, and degradation if misfolding cannot be prevented. HSP90, a member of the HSP family, is a potential target for treatment of cancer and neurodegenerative diseases. Unfortunately, several clinical trials for cancer treatment have been discontinued due to cell toxicity accompanying HSP90 inhibition. HSP90 has four distinct but structurally similar paralogs. HSP90 inhibitors target all the paralogs despite increasing proof of functional differences among the paralogs. Understanding the in vivo function of HSP90 and the role played by each paralog …
