One of the hallmarks of cancer cells is their failure to respond to the cellular mechanism of apoptosis. The B-cell lymphoma 2 (BCL-2) family of proteins regulate apoptosis. Their ability to do so can be measured using several methods that in turn anticipate the fate of the cancer cell in response to apoptosis-inducing treatment. These assays ultimately identify the readiness of the cancer cell to undergo apoptosis, which is referred to as the mitochondrial priming state. These metrics, however, have been challenging to implement in the clinic.

Central memory CD8 T cells exhibit marked veto activity enhancing engraftment in several mouse models of T cell-depleted bone marrow (TDBM) allografting. Graft-versus-host disease (GVHD) can be prevented by stimulation of mouse or human memory CD8 T cells against their cognate antigens under cytokine deprivation, in the early phase of culture followed by further expansion with IL21, IL15, and IL7. Thus, human anti-viral CD8 central memory veto T cells generated from CMV and EBV-positive donors are currently evaluated in a clinical trial at MD Anderson Cancer Centre (MDACC). Results in 15 patients indicate a low risk of GVHD. Considering that …

Neovascular Pruning By Ido1 Inhibitors Can Potentiate Immunogenic Cytotoxicity Of Ischemia-Targeted Agents To Synergistically Enhance Anti-Pd-1 Responsiveness, Shih-Chun Shen, Souvik Dey, James B. Duhadaway, Erika Sutanto-Ward, Maurice T. Hampton, Serguei V. Kozlov, George C. Prendergast, Alexander J. Muller

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Strategies for deploying indoleamine 2,3-dioxygenase 1 (IDO1)-targeted therapies for use against cancer have focused on IDO1's role in promoting peripheral immune tolerance that shields tumors from effector T cells. However, preclinical investigation of both primary and metastatic tumor development in the lungs has uncovered a previously unappreciated role for IDO1 in directing a counterregulatory response to interferon (IFN)-γ that realigns the local inflammatory environment to promote tumor neovascularization. Understanding how to therapeutically leverage the ability of IDO1 inhibitors to subvert inflammatory neovascularization within the tumor microenvironment has potential ramifications for future clinical development of these compounds.

METHODS: Pulmonary metastases …

Pontocerebellar hypoplasia (PCH) encompasses a group of autosomal recessive neurodegenerative disorders marked by cerebellar and pontine atrophy. Multiple subtypes of PCH have been identified, among which the rare subtype PCH type 16 is caused by MINPP1 genetic variants. MINPPI encodes an enzyme essential for inositol polyphosphate dephosphorylation, regulating calcium and iron homeostasis. We conducted genome sequencing on a proband from the consanguineous family, who presented with a severe neurodegenerative disorder, to identify the underlying cause of disease. A comprehensive clinical assessment in addition to neuroradiological findings are described. We performed the functional validation of the identified variant and conducted untargeted …

Aortic stenosis (AS) is one of the most common types of valvular heart disease in older adults, with age being significantly associated with the development of AS. The transcatheter aortic valve replacement (TAVR) procedure, since it was first performed in 2002, has emerged as a preferred treatment option for patients who are at intermediate to high surgical risk due to advanced age or medical comorbidities. Older adults with severe AS may present with acute decompensated heart failure leading to cardiogenic shock (CS). Among patients 65 years and older with AS presenting for TAVR, 4.1% were reportedly in acute CS. Regardless …

During cancer development, mutations promote gene expression changes that cause transformation. Leukemia is frequently associated with aberrant HOXA expression driven by translocations in nucleoporin genes or KMT2A, and mutations in NPM1. How disparate mutations converge on this regulatory pathway is not understood. Here we demonstrate that mutant NPM1 (NPM1c) forms nuclear condensates in multiple human cell lines, mouse models, and primary patient samples. We show NPM1c phase separation is necessary and sufficient to coordinate the recruitment of NUP98 and KMT2A to condensates. Through extensive mutagenesis and pharmacological destabilization of phase separation, we find that NPM1c condensates are necessary …

Biofilms are an important colonization mechanism employed by several microbial species to better establish themselves and monopolize the acquisition of resources across different environs. Some bacteria have evolved specialized metabolites that, when secreted, disrupt the formation and stability of biofilms generated by competing heterospecies, providing the producing organism with an ecological advantage. Soil-derived species are probable candidates for the identification of such compounds, given the intense level of competition that occurs within the terrestrial ecosystem. The MS14 strain of Burkholderia contaminans isolated from soil in Mississippi has previously been shown to produce antimicrobial compounds like occidiofungin and ornibactin. In this …

Targeting Neuronal Nitric Oxide Synthase (Nnos) As A Novel Approach To Enhancing The Anti-Melanoma Activity Of Immune Checkpoint Inhibitors, Anika R. Patel, Shirley Tong, Kate Alison Lozada, Amardeep Awasthi, Richard B. Silverman, Jennifer Totonchy, Sun Yang

Pharmacy Faculty Articles and Research

Background and Objectives: Neuronal nitric oxide synthase (nNOS) overexpressed in melanoma plays a critical role in disease progression. Our previous studies demonstrated that nNOS inhibitors exhibited potent anti-melanoma activity and regulated PD-L1 expressions in the presence of interferon-gamma (IFN-γ). However, the role of nNOS in the melanoma immune response has not been well defined. Methods: Changes in gene expression profiles after nNOS inhibitor treatment were determined by transcriptomic analysis. A melanoma mouse model was used to determine the effects of nNOS inhibition on peripheral T cells and the in vivo anti-tumor activity of combining nNOS inhibitors with immune …

Current vaccines rely on the sequence of Spike (S) protein to induce immunity against the severe acute respiratory coronavirus-2 (SARS-CoV-2) virus. Because of the high mutation rate of the viral S protein, new mutant strains are developed to generate new infectivity profiles. Bioactive lipid mediators (LMs) derived from docosahexaenoic acid (DHA) are synthesized on demand to sustain homeostasis. The purpose of this study was to determine the action of selected LMs in the viral replication of SARS-CoV-2 Omicron BA.5 variant in human lung and nasal epithelial cells. Cells from healthy donors were infected with Omicron BA.5 for one hour and …

Imaging Hallmarks Of Idiopathic Intracranial Hypertension And Insights Into Pathogenesis, Albalooshy Basimah, Scott Faro, Hsiangkuo Yuan, Kiran Talekar, Prabath Mondel, Enchao Qiu, Joga Chaganti

Department of Radiology Faculty Papers

Idiopathic Intracranial hypertension (IIH), also referred to as pseudotumor cerebri, is a term used to describe increased intracranial pressure in the absence of a known identifiable secondary cause. Despite advancements of neuroimaging techniques, imaging of the pathological underpinnings in the diagnosis of IIH has been limited. Although the causation of IIH has been ascribed to increased Cerebrospinal Fluid production and disordered drainage through the dural sinuses, new evidence shows that the glymphatic system which is an alternate pathway of drainage is likely to play a pivotal role. In this review, we address the pathophysiological underpinnings in the causation of IIH …

Bone metastasis is a major cause of cancer death; however, the epigenetic determinants driving this process remain elusive. Here, we report that histone methyltransferase ASH1L is genetically amplified and is required for bone metastasis in men with prostate cancer. ASH1L rewires histone methylations and cooperates with HIF-1α to induce pro-metastatic transcriptome in invading cancer cells, resulting in monocyte differentiation into lipid-associated macrophage (LA-TAM) and enhancing their pro-tumoral phenotype in the metastatic bone niche. We identified IGF-2 as a direct target of ASH1L/HIF-1α and mediates LA-TAMs' differentiation and phenotypic changes by reprogramming oxidative phosphorylation. Pharmacologic inhibition of the ASH1L-HIF-1α-macrophages axis elicits …

Laminin B1 (LAMB1) is one of the extracellular matrix (ECM) proteins that make up the basement membrane. Early frameshift, late frameshift, and missense variants in LAMB1 have been reported to cause rare monogenic neurological disorders that are collectively known as LAMB1-related leukoencephalopathy. Although there is some genotype-phenotype correlation, functional consequences of pathogenic LAMB1 variants are largely unknown. In this study, we aimed to elucidate function of the fly ortholog of this gene (LanB1) in the nervous system and to further study the functional consequences of the LAMB1 variants using Drosophila melanogaster. We found that the LanB1 gene is expressed on …

Adults' Intention To Take An Arthritis Prescription Drug Based On Drug Advertisements, Amanda Radola

Seton Hall University Dissertations and Theses (ETDs)

Direct-to-Consumer Prescription Advertising (DTCPA) has rapidly expanded, particularly via social media, but research on its influence on individual decisions regarding prescribed medications remains limited. This gap is notable among chronic disease patients, such as those with arthritis, which affected over 58.5 million U.S. adults as of 2015 and is projected to rise to 78.4 million by 2040 (Barbour et al., 2017; Hootman et al., 2016). Social media discussions show significant activity following television ads for arthritis drugs (Curtis et al., 2017). However, few studies explore how DTCPA impacts patient intentions to take advertised arthritis medications. This study employed a novel …

Peripheral Neuroimmune Mechanisms Of Chronic Back Pain, Aleyah Esther Goins

Biomedical Sciences ETDs

Chronic back pain (CBP) affects 1 in 10 people worldwide, reducing mobility, productivity, and quality of life. Despite its prevalence, non-addictive treatments remain limited due to an incomplete understanding of chronic pain mechanisms. This dissertation examines peripheral neuroimmune interactions in CBP using a urokinase-type plasminogen activator (uPA)-induced mouse model (uPA-CBP). uPA, a pro-inflammatory serine protease, was injected into the L2/L3 lumbar spinous ligament, inducing prolonged mechanical and cold hypersensitivity. Flow cytometry of dorsal root ganglia (DRG) showed increased CD45+CD11b+ myeloid cells in males and CD45+CD3+CD4+ lymphocytes in females. DRG neurons from male uPA-CBP mice exhibited heightened action potential firing. Pharmacological …

Glycosylation controls immune evasion, tumor progression, and metastasis. However, how tumor cell sialylation regulates immune evasion remains poorly characterized. ST6GalNAc-I, a sialyltransferase that conjugates sialic acid to the glycans in glycoproteins, was overexpressed in an aggressive-type KPA (KrasG12D/+ Trp53R172H/+ Ad-Cre) lung adenocarcinoma (LUAD) model and patient samples. Proteomic and biochemical analysis indicated that ST6GalNAc-I mediated NECTIN2 sialylation in LUAD cells. ST6GalNAc-I-deficient tumor cells cocultured with T cells were more susceptible to T cell-mediated tumor cell killing, indicating a key role for NECTIN2 in T cell dysfunction. Mice injected with St6galnac-I-knockdown syngeneic cells showed reduced lung tumor incidence and Nectin2/Tigit-associated immunosuppression. …

Candida is one of the most frequent causes of bloodstream infections, and our first line of defense against these invasive infections is the innate immune system. The early immune response is critical in controlling Candida albicans infection, but C. albicans has several strategies to evade host immune attack. Phagocytosis of C. albicans blocks hyphal growth, limiting host damage and virulence, but how C. albicans limits early recruitment and phagocytosis in vertebrate infection is poorly understood. To study innate immune evasion by intravital imaging, we utilized the transparent larval zebrafish infection model to screen 131 C. albicans mutants for altered …

IDH-wildtype glioblastoma (GBM) is an aggressive brain tumor with poor survival and few therapeutic options. Transcriptionally-defined cell states coexist in GBM and occupy defined regions of the tumor. Evidence indicates that GBM cell states are plastic, but it remains unclear if they are determined by the underlying epigenetic state and/or by microenvironmental factors. Here, we present spatially-resolved epigenomic profiling of human GBM tissues that implicate chromatin structure as a key enabler of cell plasticity. We report two epigenetically-defined and spatially-nested tumor niches. Each niche activates short-range molecular signals to maintain its own state and, surprisingly, long-range signals to reinforce …

Relationship Between Maternal Plasma Retinol And Provitamin A Carotenoids With Fetal And Infant Kidney Development, Anum Akbar

Theses & Dissertations

Vitamin A plays a critical role in fetal organ development. Studies suggest that maternal vitamin A deficiency affects fetal nephron numbers, potentially leading to smaller kidney sizes and an increased risk of chronic kidney disease later in life. However, human studies exploring maternal vitamin A's impact on fetal kidney development lack longitudinal data and within-cohort comparisons. Furthermore, the influence of provitamin A carotenoids (α-carotene, β-carotene, β-cryptoxanthin) on kidney size remains unexplored. This dissertation addresses these gaps by analyzing relationships between maternal and cord plasma retinol and provitamin A carotenoid concentrations with fetal and infant kidney sizes. Our prospective cohort …
