Functions Of Adp-Ribose Transferases In The Maintenance Of Telomere Integrity, Daniela Muoio, Natalie Laspata, Elise Fouquerel

Department of Biochemistry and Molecular Biology Faculty Papers

The ADP-ribose transferase (ART) family comprises 17 enzymes that catalyze mono- or poly-ADP-ribosylation, a post-translational modification of proteins. Present in all subcellular compartments, ARTs are implicated in a growing number of biological processes including DNA repair, replication, transcription regulation, intra- and extra-cellular signaling, viral infection and cell death. Five members of the family, PARP1, PARP2, PARP3, tankyrase 1 and tankyrase 2 are mainly described for their crucial functions in the maintenance of genome stability. It is well established that the most describedrole of PARP1, 2 and 3 is the repair of DNA lesions while tankyrases 1 and 2 are crucial …

The Use Of Nucleotide Salvage Pathway Enzymes As Suitable Tumor Targets For Antibody-Based And Adoptive Cell Therapies, Edwin J. Velazquez

Theses and Dissertations

Despite the progress made in cancer research, cancer remains one of the leading causes of death worldwide. Although the development of new cancer treatments has improved cancer patients' survival rate, a significant number of patients experience refractory and recurrence events with serious side effects. It is known that the immune system actively participates in eliminating cancer. However, cancer cells can develop mechanisms to evade the immune system resulting in immunotolerance. Immunotherapy aids the patient's immune system's ability to recognize and eliminate cancer cells. During the last three decades, immunotherapy has gradually emerged as an effective and more specific approach to …

The Inhibition Of Valproic Acid-Induced Negative Neurodevelopmental Outcomes Through Nrf2-Mediated Redox Regulation, Ted Brenton Piorczynski

Theses and Dissertations

Valproic acid (VPA) is a commonly prescribed antiepileptic drug that causes negative neurodevelopmental outcomes, including neural tube defects (NTDs) and neurodevelopmental disorders, in fetuses exposed to it. While the exact mechanism by which VPA causes defects is unknown, research has shown that VPA increases the production of reactive oxygen species (ROS) that lead to redox dysregulation. We hypothesize that VPA causes negative neurodevelopmental outcomes through the disruption of redox-sensitive signaling pathways that are critical for proper embryonic development, and that protection from the VPA-induced redox disruption may decrease the prevalence of the observed defects. Time-bred mice were treated with 3H-1,2-dithiole-3-thione …

Faculty, Staff and Student Publications

Despite the success of immune checkpoint inhibitor (ICI) therapy for cancer, resistance and relapse are frequent. Combination therapies are expected to enhance response rates and overcome this resistance. Herein, we report that combining PRMT7 inhibition with ICI therapy induces a strong anti-tumor T cell immunity and restrains tumor growth in vivo by increasing immune cell infiltration. PRMT7-deficient B16.F10 melanoma exhibits increased expression of genes in the interferon pathway, antigen presentation, and chemokine signaling. PRMT7 deficiency or inhibition with SGC3027 in B16.F10 melanoma results in reduced DNMT expression, loss of DNA methylation in the regulatory regions of endogenous retroviral elements (ERVs) …

Ohio Anuran Gut Microbiomes, Serena Hoffman

Undergraduate Honors Thesis Projects

Recent studies focusing on the skin and gut microbiome of vertebrates have found how important microbiomes are to maintaining host health. Understanding the role the gut microbiome plays to host health is of great importance for conservation. Less is known about the gut microbiome than the skin microbiome for amphibians. Literature is especially lacking for local Ohio anuran species. The purpose of this study was to establish the baseline composition of the gut microbiome for local Ohio anurans and to determine whether host species or habitat is the best predictor of gut microbiome composition. Tadpoles were collected from seven different …

Faculty Research, Scholarly, and Creative Activity

Traditional knowledge, along with archaeological and linguistic evidence, documents that California supports cultural and linguistically diverse Indigenous populations. Studies that have included ancient genomes in this region, however, have focused primarily on broad-scale migration history of the North American continent, with relatively little attention to local population dynamics. Here, in a partnership involving researchers and the Muwekma Ohlone tribe, we analyze genomic data from ancient and present-day individuals from the San Francisco Bay Area in California: 12 ancient individuals dated to 1905 to 1826 and 601 to 184 calibrated years before the present (cal BP) from two archaeological sites and …

Application Of The Riemann-Hilbert Method To Soliton Solutions Of A Nonlocal Reverse-Spacetime Sasa-Satsuma Equation And A Higher-Order Reverse-Time Nls-Type Equation, Ahmed Ahmed

USF Tampa Graduate Theses and Dissertations

For many years, the study of integrable systems has been one of the most fascinating branches of mathematics and has been thought to be an interesting area for both mathematicians and physicists alike.Many natural phenomena can be predicted by using integrable systems, particularly by studying their different solutions, as well as analyzing and exploring their properties and structures. They are commonly found in nonlinear optics, plasmas, ocean and water waves, gravitational fields, and fluid dynamics. Typical examples of integrable systems include the Korteweg-de Vries (KdV) equation, the nonlinear Schrödinger (NLS) equation, and the Kadomtsev-Petviashvili (KP) equation. Solitons are intrinsic solutions …

Development Of Enhanced Algae Strains And Sustainable Cultivation Processes For Production Of Algal Lipids For Biofuels And Bioproducts, Enlin Lo

USF Tampa Graduate Theses and Dissertations

The establishment of an algae industry is crucial for addressing global biofuel and bioproduct demand that meets the Sustainable Development Goals (SDG) worldwide. Photosynthetic microalgae are excellent sources for food, fiber, fuel, feed, and fertilizer, which are the 5Fs of the SDG. However, at present, algae-based materials are not cost-competitive or sufficiently sustainable. Improved productivity, lower cultivation cost, and reduced use of resources are required to transition from lab to industry, necessitating the development of superior strains that have high productivity and can tolerate environmental stress, such as temperature and salinity, so they can be cultivated at large scale outdoors …

Defining The Role Of Oxidized Mitochondrial Dna In Myelodysplastic Syndromes, Grace Anne Ward

USF Tampa Graduate Theses and Dissertations

Myelodysplastic Syndromes (MDS) are heterogeneous bone marrow (BM) failure malignancies characterized by constitutive innate immune activation, NLRP3 inflammasome (IFM) driven pyroptotic cell death, and the induction of interferon-stimulated genes (ISG). MDS often diagnostically resembles other hematologic disorders, as such, additional tools are needed for the discrimination from overlapping disorders. We observed that oxidized mitochondrial DNA (ox-mtDNA) is released upon cytolysis. We hypothesize that levels of ox-mtDNA are high in MDS, allowing us to use it as a diagnostic biomarker; and that cell free ox-mtDNA is contributing to feedforward BM failure.

ROC/AUC analysis demonstrated that ox-mtDNA is a sensitive and specific …

Individual Differences In Response To Hostile And Benevolent Sexism In A Stem Interview Context: The Moderating Role Of Behavioral Activation, Elizabeth Kiebel

USF Tampa Graduate Theses and Dissertations

Women continue to face sexism in workplace contexts, especially those that are male dominated, such as science, technology, engineering, and mathematics (STEM). Yet, women often fail to confront the sexism they experience, despite confrontation being an effective way to cope with and prevent future harassment (Fitzgerald et al., 1995; Magley, 2002). To date, no one has assessed the potential moderating role of personality differences related to approach motivation on women’s confrontation of sexism. In this study, women were exposed to either a hostilely sexist or benevolently sexist question during a mock job interview that was purportedly being conducted as part …

Small Heat Shock Protein 22 Preserves Neuronal Function In A Murine Model Of Tauopathy, Santiago Rodriguez Ospina

USF Tampa Graduate Theses and Dissertations

Proteinopathies is a family of diseases associated with the pathological aggregation of protein. There are a multitude of proteinopathies, like tauopathy and synucleinopathy that contribute to neurodegenerative diseases like Alzheimer’s disease (AD), Creutzfeldt-Jakob, Pick’s disease, Frontotemporal dementia, and Parkinson’s disease (PD). Currently, one focus of research in the field is mitigating aggregation-prone proteins contributing to disease state. One method of targeting aggregation is the use of chaperones. Chaperones are molecular machinery that help maintain homeostasis in the cells, through various roles and mechanisms, one of those methods is to regulate protein aggregation. Chaperones can achieve this by affecting protein-protein interactions, …

Petrie, Arturo Rodriguez, Henry Presas, Jesus Rodriguez, Fred Barnes, Christopher Vitek, Xochitl Estrada, Thalia Rios, Jeremy Marshall

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The diel biting activity of Aedes (Stegomyia) aegypti (L) populations was extensively investigated in the early 1900s to gain more information on the biology of Ae. aegypti, and this information was used to devise effective approaches to controlling populations of this species and protect the human population from widespread arbovirus outbreaks. However, few contemporary studies are available regarding the diel activity patterns of Ae. aegypti. To assess the diel activity patterns of Ae. aegypti in southern Florida and Texas, we conducted 96-h uninterrupted mosquito collections once each month from May through November 2019 in Miami, Florida, and Brownsville, Texas, using …

Neural stem cells, the source of newborn neurons in the adult hippocampus, are intimately involved in learning and memory, mood, and stress response. Despite considerable progress in understanding the biology of neural stem cells and neurogenesis, regulating the neural stem cell population precisely has remained elusive because we have lacked the specific targets to stimulate their proliferation and neurogenesis. The orphan nuclear receptor TLX/NR2E1 governs neural stem and progenitor cell self-renewal and proliferation, but the precise mechanism by which it accomplishes this is not well understood because its endogenous ligand is not known. Here, we identify oleic acid (18:1ω9 monounsaturated …

Stronger Microstructural Damage Revealed In Multiple Sclerosis Lesions With Central Vein Sign By Quantitative Gradient Echo Mri, Victoria A Levasseur, Biao Xiang, Amber Salter, Dmitriy A Yablonskiy, Anne H Cross

2020-Current year OA Pubs

BACKGROUND: Multiple sclerosis (MS) lesions typically form around a central vein that can be visualized with FLAIR* MRI, creating the central vein sign (CVS) which may reflect lesion pathophysiology. Herein we used gradient echo plural contrast imaging (GEPCI) MRI to simultaneously visualize CVS and measure tissue damage in MS lesions. We examined CVS in relation to tissue integrity in white matter (WM) lesions and among MS subtypes.

OBJECTIVE: We aimed to determine if CVS positive lesions were specific to MS subtype, if CVS can be detected consistently among readers using the GEPCI method, and if there were differences in tissue …

Thinking Creatively About Functional Diversity And Functional Traits (Bef), Shahid Naeem

Sustainability Seminar Series

Understanding the impacts of biodiversity loss on ecosystem functions and services represents a major focus of contemporary environmental biology, but its progress hinges on advances in the study of functional diversity. Traditional approaches to functional diversity, however, have centered on taking virtually any measure of an organism’s biology, or an organism’s functional traits (OFTs), often assuming that variation in OFTs among species reflects ecological and evolutionary tradeoffs. Contemporary issues, however, require more creative approaches to the quantification and analysis of OFTs. Here, I present results from four of our group’s research that illustrate the value of more creative approaches to …

Efforts To Increase The Ketamine-Like Activity Of The Rapid-Acting Antidepressant Ro-25-6981 (Mi-4) By Increasing Ampa Potentiation, Nathan Heger

Annual Research Symposium

The small molecule ketamine has generated much interest due to its rapid antidepressant effects. Despite having a rapid onset, ketamine has poor bioavailability, short duration of action, toxicities with long-term use, and a high potential for abuse. The molecule MI-4 (RO 25-6981) has also been shown to have both a rapid and sustained antidepressant effect. Most of the research into the mechanism of the rapid onset of MI-4 and ketamine has focused on their interaction with the NMDA receptor in addition to some monoamine transporters. Some recent publications have shown a significant role of AMPA receptors in the ketamine antidepressant …
