Mutations in the tumor suppressor gene TP53 have been identified in breast cancer-associated fibroblasts and are associated with poor patient prognosis. However, the functional impact of fibroblastic mutant p53 on breast cancer development remains unclear. To investigate this, we compared female mice harboring HER2-driven mammary tumors with a fibroblast-specific Trp53 mutation (NP) to those with wild-type fibroblastic Trp53 (N). NP mice exhibited significantly shorter median tumor-free survival than N mice. RNA sequencing of NP and N tumors and mammary glands revealed numerous differentially expressed genes (DEGs) between tumors and the corresponding glands in both genotypes. Notably, the NP tumors showed …

Escalated doses of radiotherapy associate with improved local control and overall survival (OS) in intrahepatic cholangiocarcinoma (iCCA), but personalization remains limited because conventional size-based CT criteria correlate poorly with outcomes. We hypothesized that quantitative enhancement measurements would better predict clinical outcomes and guide individualized RT optimization. In a retrospective cohort of 154 patients, we analyzed pre- and post-RT CT scans using quantitative European Association for Study of Liver (qEASL) to derive viable tumor volumes, comparing enhancement-based metrics with size-based RECIST and linking them to outcomes via survival and mathematical modeling. Change in enhancement volume was strongly associated with OS after …

The study investigates the sex-specific effects of the pluripotency factor OCT4 deficiency in endothelial cells (ECs) on angiogenesis. OCT4 is known for its role in embryonic stem cells, but we recently found that it plays a protective role in ECs during atherosclerosis. Herein, we utilized cultured mouse aortic ECs (MAECs) and several in vivo models, including skin wounding, melanoma tumor implantation, and hindlimb ischemia, to explore the role of OCT4 in angiogenesis in both male and female mice. Our findings revealed significant sexual dimorphism in wild type mice, along with sex differences in responses to OCT4 deficiency across all three …

The Pressure Is On: A Quality Improvement Project To Educate Nurses On Hospital Acquired Pressure Injuries, Lance Ward

Master's Projects and Capstones

Objective Hospital acquired pressure injuries (HAPIs) are injuries developed by admitted patients, from treatment interventions that they encounter during their hospital stay. If a patient acquires a HAPI during their stay, the hospital is required to cover all expenses related to the injury. An in-patient trauma unit at a large medical center wishes to improve patient care by educating nursing staff on preventive measures of HAPIs. A review of relevant literature on HAPIs from the past five years was conducted to identify HAPI preventions tools, such as the Braden Scale and SKINS bundle, as well as the best methods to …

The rise of antimicrobial-resistant bacteria in the healthcare industry has led to devastating effects in recent years, ranging from increased risks associated with hospital treatment to longer illness duration, which may eventually lead to increased death rates (Naghavi, Mohsen et al, 2024). To combat this ongoing challenge, this project aims to synthesize amidoximes, which are organic derivatives of carboxylic acids with an oxime and an amino acid group. Amidoximes have been utilized in various clinical applications, including antituberculosis medication, hypotensives, antiarrhythmics, antibacterials, and antifungals (J. Chil et al., 2011). -- The focus of this project was to test their antibacterial …

Matrescence: An Emerging Concept For Birth Worker Practice, Kelsey B. Green

DNP Qualifying Manuscripts

The maternal mental health (MMH) crisis, affecting up to 25% of birthing individuals, is exacerbated by significant gaps in perinatal support. While birth workers are uniquely positioned to provide care, they often lack specialized training beyond basic screening checklists to address the complex transition to motherhood, defined as matrescence. This clinical innovation proposal outlines a matrescence-informed educational curriculum, guided by the Comprehensive Model of Mental Health during the Perinatal Period. The intervention is designed to build tangible, implementable skills, training birth workers to: (1) operationalize matrescence as a psychoeducational tool to normalize distress; (2) use clinical differentiation to distinguish the …

Role Of Cellular Stress Responses In Innate Immune Defense Against Acute Respiratory Infections, Amit Sharma

LSU Doctoral Dissertations

The endoplasmic reticulum (ER) stress sensor inositol-requiring enzyme 1α (IRE1α) is an important regulator of innate immune cells. However, its role in pulmonary innate host defenses remains poorly understood. This dissertation elucidates the dual, context-dependent role of IRE1α in host defense against methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. We demonstrate IRE1α’s function as both a detrimental mediator of acute pathology and an essential facilitator of innate immune memory. Our work revealed that acute IRE1α activation during primary MRSA infection is detrimental. In lungs and alveolar macrophages (AMs), IRE1α is activated in response to MRSA infection. Consequently, IRE1α activation triggers a hyperinflammatory …

Walden Dissertations and Doctoral Studies

The COVID-19 pandemic necessitated an shift to mandatory virtual learning (VL) for kindergarten through grade 12 students, disrupting educational systems globally and exposing systemic inequities. Although researchers had explored health and education disparities separately, they had not adequately examined the intersection of child health, specifically body mass index (BMI) and health-affected ability, with school readiness and level of distraction in VL environments. The purpose of this quantitative, cross-sectional study was to examine associations between BMI, health affected ability, school readiness, and distraction levels among U.S. Black children engaged in VL in the 2020 school year, controlling for gender, age, and …

Structural Basis Of Panx1 Permeation And Positive Modulation By Mefloquine, Yangyang Li, Zheng Ruan, Junuk Lee, Ian Orozco, Edward Zhou, Juan Du, Wei Lü

Department of Biochemistry and Molecular Biology Faculty Papers

Purinergic signaling relies on ATP release through exocytosis and large-pore channels. Large-pore channels permeate both small anions like chloride and large signaling molecules like ATP, but how this broad cargo selectivity is structurally controlled remains elusive. Here we investigate PANX1, a prototypical large-pore channel, and uncover structural plasticity at the extracellular entrance formed by seven tryptophan (W74) residues. The W74 sidechains are flexible, sampling conformations that range from a constricted state permissive only to chloride to a dilated state compatible with ATP. These states are coupled to variable cation-π interactions between W74 and arginine 75 (R75), suggesting a mechanism for …

The Moral Crisis Of Maternal Mortality In The Us, Jensen F. Ware

Honors Theses

This thesis argues that the US crisis of maternal mortality is not an unavoidable tragedy, but a moral and policy failure. I argue that maternal well‑being is one of the most important indicators of a society’s overall health. When mothers receive the care, respect, and support they need, it reflects the strength of healthcare systems, the culture, and our commitment to future generations. The continued loss of mothers from preventable deaths reveals a system that fails many women and their families, especially Black women, low‑income women, and those in rural communities. First, I introduce the issue of maternal mortality in …

Faculty, Staff and Student Publications

Parkinson's disease (PD), Dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), are characterized by the misfolding and aggregation of alpha-synuclein (αSyn). Compelling evidence showed that αSyn aggregates exist as distinct conformational strains in different synucleinopathies. Recently, we reported that the αSyn Seed Amplification Assay (αSyn-SAA) can amplify and distinguish αSyn strains from PD and MSA. In this study, we investigate whether MSA-seeded, SAA-amplified αSyn fibrils retain the biological and structural properties of the αSyn seeds present in MSA brains. We study the biological activities of both brain-derived and SAA-amplified αSyn aggregates using an αSyn "biosensor" cell model and …

Elevated Lactate In Aml Bone Marrow Contributes To Macrophage Polarization Via Gpr81 Signaling., Celia A Soto, Maggie L Lesch, Jennifer L Becker, Azmeer Sharipol, Amal Khan, Xenia L Schafer, Zhewen Li, Amanda R Streeter, Michael W Becker, Joshua C Munger, Benjamin J Frisch

Oncology Articles

Interactions between acute myeloid leukemia (AML) and the bone marrow microenvironment (BMME) are critical to leukemia progression and chemoresistance. In the solid tumor microenvironment, altered metabolite levels contribute to cancer progression. We performed a metabolomic analysis of AML patient bone marrow serum, revealing increased metabolites compared to age- and sex-matched controls. The most highly elevated metabolite in the AML BMME was lactate. Lactate signaling in solid tumors induces immunosuppressive tumor-associated macrophages and correlates with poor prognosis. This has not yet been studied in the leukemic BMME. Herein, we describe the role of lactate in the polarization of leukemia-associated macrophages (LAMs). …
