University Faculty Publications and Creative Works

Digestion elevates metabolism through the heat increment of feeding (HIF) – the energy expended on mechanical and biochemical processes after eating. Quantifying this cost is essential for bioenergetic models that predict energy flow and prey requirements in populations. Using breath-by-breath respirometry, we measured oxygen consumption (V̇ O2 ) in eight common bottlenose dolphins (Tursiops truncatus) before and after feeding standardized meals (1659–2658 kcal of capelin and herring). Metabolic rate rose by ∼37% above resting levels, peaking 60 min after feeding before returning to baseline within 2 h. When scaled across the day, digestion increased daily metabolic needs by ∼8.2% of …

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 …

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 …

Trace Mineral Supplementation Strategies For Beef Cattle During Preconditioning And Feedlot Receiving, Madeline G. Mcknight

Theses and Dissertations

Beef cattle routinely undergo a variety of stressors within the preconditioning and feedlot receiving phases which may impair animal performance and health. Trace mineral supplementation, either through dietary or injectable sources, is proposed to mitigate these effects through metabolic and immune system support. Two systematic reviews and meta-analyses were conducted to evaluate the efficacy of two different oral supplementation methods, organic (OTM) and inorganic (INR), and injectable trace mineral (ITM) solutions on average daily gain (ADG) and morbidity. Across 20 studies, OTM supplementation increased ADG (P = 0.01) when compared to INR, but did not affect morbidity (P = 0.92). …


Mitochondrial Calcium Uniporter Regulates Itam-Dependent Platelet Activation, Jehiel Abigail Ajanel Gomez Dec 2025

Mitochondrial Calcium Uniporter Regulates Itam-Dependent Platelet Activation, Jehiel Abigail Ajanel Gomez

Arts & Sciences Graduate Student Theses and Dissertations

Thromboembolic conditions are the leading cause of disability and death in the United States. Platelets play an important role in the pathophysiology of thrombus formation by aiding in the formation and stabilization of the clot. Central to platelet activation is cytoplasmic calcium, which increases after platelet activation through ITAM (Immunoreceptor tyrosine-based activation motif) or GPCR (G-protein-coupled receptor) receptors. Platelet mitochondria rely on cytoplasmic calcium for mitochondrial calcium influx, which is critical for ATP formation and regulation of mitochondrial reactive oxygen species. In other cells, mitochondrial calcium entry is regulated by the multimeric protein complex, mitochondrial calcium uniporter (MCU). Deletion of …


Understanding Outer Membrane Vesicle Biogenesis In Bacteroides Thetaiotaomicron, Evan J. Pardue Dec 2025

Understanding Outer Membrane Vesicle Biogenesis In Bacteroides Thetaiotaomicron, Evan J. Pardue

Arts & Sciences Graduate Student Theses and Dissertations

Outer membrane vesicles (OMVs) are small proteoliposomes generated by active protrusion of the outer membrane (OM) in Gram-negative bacteria during growth. Over 60 years of experimentation has ascribed numerous functions to OMVs produced by different bacteria. However, the mechanism(s) by which OMVs are produced is poorly understood. Due to this, the field remains controversial because many regard OMVs as byproducts of cell lysis and question their physiological relevance. Previous studies in Pseudomonas aeruginosa and related species confirmed that these microbes undergo programmed cell death that results in the stochastic release of vesicles and cellular contents. On the contrary, Bacteroides spp. …

Faculty, Staff and Student Publications

The morphology of the endoplasmic reticulum (ER), characterized by central sheets and peripheral tubules, is controlled by membrane-shaping proteins. However, the role of lipids in ER morphogenesis remains elusive, despite the ER being the major site for lipid synthesis. Here, by examining the role of eighteen phosphatidic acid (PA)-generating enzymes in ER morphology, we identify lysophosphatidic acid acyltransferase 2 (AGPAT2) as a critical factor in mouse and human cells. AGPAT2 produces PA in the glycerophospholipid/triacylglycerol biosynthesis pathway, and its mutations cause congenital generalized lipodystrophy. We find that AGPAT2-generated PA drives ER tubulation through gene knockout, 3D structural analysis by FIB-SEM, …

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 Role Of Toll-Like Receptors In Tributyltin, Dibutyltin, And Pentachlorophenol Stimulation Of Tumor Necrosis Factor Alpha Production By Human Immune Cells, Latoya Michelle Daniel

Tennessee State University Alumni Theses and Dissertations

Tributyltin (TBT), Dibutyltin (DBT), and Pentachlorophenol (PCP) are persistent environmental contaminants that have been shown to increase immune-cell production of pro-inflammatory cytokines and thus have the capacity to cause chronic inflammation and its associated pathologies such as cancer, cardiovascular disorders, and autoimmune conditions. TBT has been detected in human blood at concentrations up to 260 nM, DBT up to 0.3 µM, and PCP between 0.15 and 5 µM. Tumor necrosis factor-alpha (TNF-α) is a pro-inflammatory cytokine produced by immune cells in response to pathogen- or damage-associated molecular patterns (PAMPs/DAMPs) via Toll-like receptors (TLRs). Dysregulated TNF-α production contributes to chronic inflammatory …

Role Of Cellular Stress Responses In Innate Immune Defense Against Acute Respiratory Infections, Amit Sharma Dec 2025

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 …

Variable expressivity of disease-associated variants implies a role for secondary variants that modify clinical features. We assessed the effects of modifier variants on the clinical outcomes of 2,455 individuals with primary variants. Among 124 families with the 16p12.1 deletion, distinct rare and common variant classes conferred risks for specific developmental features, including short tandem repeats for neurological defects. Network analysis suggested distinct mechanisms involving 16p12.1 genes and secondary variants specific to each proband. Within disease and population cohorts of 976 individuals with the 16p12.1 deletion, we found opposing effects of secondary variants on clinical features across ascertainments. Additional analysis of …
