Contribution Of Contextual Factors And Neuropathology To Dementia, Monica E. Nelson Jun 2023

Contribution Of Contextual Factors And Neuropathology To Dementia, Monica E. Nelson

USF Tampa Graduate Theses and Dissertations

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that has extensive biological heterogeneity. It is not clear the extent to which this heterogeneity may be detected in participants without dementia, how it relates to incident AD dementia, and whether contextual factors may change how neuropathology relates to incident AD dementia. Therefore, this dissertation was completed using data from the Alzheimer’s Disease Neuroimaging Initiative (ADNI; n = 1,703) and the Czech Brain Aging Study (CBAS; n = 385) to address the following aims: to assess biological heterogeneity in participants without dementia, to relate this heterogeneity to incident AD dementia, and to …

“They’Re Still Trying To Wrap Their Head Around Forever”: An Anatomy Of Hope For Spinal Cord Injury Patients, William A. Lucas Apr 2023

“They’Re Still Trying To Wrap Their Head Around Forever”: An Anatomy Of Hope For Spinal Cord Injury Patients, William A. Lucas

USF Tampa Graduate Theses and Dissertations

This dissertation draws on ethnographic data to investigate the nature of spinal cord injury (SCI) rehabilitation in Central Florida, using participant observation and interview data to understand how people with SCI (pwSCI) conceptualize their own disabilities after experiencing such radical alterations in their subjectivities. Using case studies and ethnographic vignettes, it argues that the extreme double binds in which pwSCI find themselves (where they are personally ordinarily disabled and socially extraordinarily novel; and where they are enabled resources to pursue “hopeful” therapy modalities while being designated as hopelessly disabled) is further polarized by the various legislative regimes of truth in …

Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan Mar 2023

Pamam- Cyclodextrin Conjugate Upregulates Brain-Derived Neurotropic Factor In Arpe-19 Cells, Gopika Ashokan

USF Tampa Graduate Theses and Dissertations

Background: Traumatic Brain Injury (TBI) is a major contributor to death and disability due to motorvehicle accidents, sports, physical abuse, and battlefield injuries. The primary insult to the brain leads to inflammation, vascular dysfunction, and oxidative stress in the brain as well as in the eye. This leads to loss of Retinal Ganglion Cells (RGCs) and downregulation of Brain derived Neurotopic Factor (BDNF). BDNF is a neurotrophic factor that binds to Tropomyosin Receptor Kinase B (TrkB) receptor to promote cell growth, survival, and differentiation. Current treatment strategies do not promote neuronal regeneration. Therefore, novel treatments are needed to restore vision …

Intimate Conversations: A Mixed-Methods Study Of African American Father-Adolescent Sexual Risk Communication, Shanda A. Vereen

USF Tampa Graduate Theses and Dissertations

Background: Approximately 50% of African American (AA) high school students are sexually active and a large proportion of sexually active AA students report engaging in sexual risk behaviors such as not using condoms at last intercourse. Consequently, AA adolescents in the United States experience outcomes of risky sexual behaviors at high rates. Evidence shows parents have an effect on shaping adolescent attitudes, values, and beliefs regarding sex through sexual risk communication (SRC). Although parent-adolescent SRC is associated with reductions in sexual risk behaviors among AA adolescents, research has primarily focused on mothers. While parents acknowledge that SRC is traditionally viewed …

Role Of Hla-Drb1 Fucosylation In Anti-Melanoma Immunity, Daniel K. Lester Mar 2023

Role Of Hla-Drb1 Fucosylation In Anti-Melanoma Immunity, Daniel K. Lester

USF Tampa Graduate Theses and Dissertations

Melanoma is the one of the most lethal skin malignancies due to its ability to rapidly metastasize and evade the immune system. One factor that influences melanoma’s ability to metastasize and evade the immune system is the tumor microenvironment. The tumor microenvironment is a complex ecosystem that consists of melanoma cells interacting with different proteins and cell types such as cytokines, extra cellular matrix proteins, and various immune cells. While different immune cells can have various implications in the tumor microenvironment, some tumor infiltrating lymphocytes (TIL) have the potential to suppress these tumors. Recent therapeutic strategies aim to enhance TILs …

Diet And Salivary Microbiome On Cardiovascular Risk And Glycemic Control In Participants With And Without Type 1 Diabetes: The Cacti Study, Tiantian Pang

USF Tampa Graduate Theses and Dissertations

Introduction: The prevalence of type 1 diabetes mellitus (T1DM) has been increasing drastically in the United States. People with T1DM are at a higher risk of developing diabetes-related complications, including cardiovascular disease (CVD). Diet is one of the most modifiable factors and healthy eating could reduce CVD risk among individuals with T1DM. The current 2015-2020 Dietary Guidelines for Americans focus on overall healthy eating patterns rather than individual foods and nutrients. A healthy dietary pattern or high-quality diet can be measured by diet quality indexes, and generally contains minimal ultra-processed foods (UPF). Although substantial evidence has linked poor diet quality …

Bioinformatic Analysis Predicts Microglial Dysfunction In Murine Aging, Amadu Idrisa Jalloh Mar 2023

Bioinformatic Analysis Predicts Microglial Dysfunction In Murine Aging, Amadu Idrisa Jalloh

USF Tampa Graduate Theses and Dissertations

Age-related disease is a growing concern as the global geriatric population increases. Neurodegenerative diseases scale unfavorably in prevalence with aging and inflict disastrous consequences to human health and well-being. These disorders are challenging to investigate because they arise from complex molecular origins. The neuroimmune system is a common factor among these diseases and microglia play an important role in maintaining homeostasis in the central nervous system. Aging progressively impairs microglia by decreasing their ability to adapt and respond to noxious environmental stimuli or injury. Microglial dysfunction aggravates neurodegenerative pathology when microglia are unable to regulate neuroinflammation effectively. We investigated aging …

Histone Deacetylase 8 Is A Novel Therapeutic Target For Mantle Cell Lymphoma And Preserves Natural Killer Cell Cytotoxic Function, January M. Watters

USF Tampa Graduate Theses and Dissertations

This study demonstrates for the first time that HDAC8 function is critical for MCL survival, and abrogating its activity in human primary NK cells does not interfere with NK IgG antibody directed ADCC therapies ex vivo. Human NK cells, isolated from healthy donors, are highly resistant to HDAC8 inhibitor treatment with PCI-34051. Even at the highest concentration, 20uM, no toxicity was observed. Conversely, MCL cell lines representative of the aggressive MCL subtype, classical MCL, were especially sensitive to PCI-34051, an HDAC8 selective inhibitor, treatment. Blocking HDAC8 activity and/or abrogating expression through shRNA silencing induced significant DNA damage, hyperacetylation of SMC3, …

Development And Implementation Of Telemetry Devices To Identify And Characterize Sources Of Intraocular Pressure Variability In Rats, Christina M. Nicou

USF Tampa Graduate Theses and Dissertations

Eye health depends partially on intraocular pressure (IOP) as abnormal levels can lead to ocular tissue damage. Glaucoma is a neurodegenerative disease that affects nearly 80 million people worldwide [1]. It is associated with elevated IOP, which can lead to irreversible blindness. Relatively little is known about IOP dynamics and the physiological factors that affect it as IOP is typically monitored using tonometry. Tonometry is a common tool used by clinicians and researchers to measure IOP noninvasively. It provides a good estimate of IOP mean but not variance because data collection takes time. Readings can also be influenced by subject …

Apkcs Role In Neuroblastoma Cell Signaling Cascades And Implications Of Apkcs Inhibitors As Potential Therapeutics, Sloan Breedy

USF Tampa Graduate Theses and Dissertations

Neuroblastoma (NB) is a cancer that develops in the neuroblasts. It is the most common cancer in children under the age of 1 year, accounting for approximately 6% of all cancers. The prognosis of NB is linked to both age and degree of cell differentiation. This results in a range of survival rates for patients, with outcomes ranging from recurrence and mortality to high survival rates and tumor regression. Our previous work indicated that PKC-ι promotes cell proliferation in NB cells through the PKC-ι/Cdk7/Cdk2 cascade. We report on two atypical protein kinase inhibitors as potential therapeutic candidates against BE(2)-C and …

On The Potential Therapeutic Roles Of Taurine In Autism Spectrum Disorder, Alberto Rubio-Casillas, Elrashdy M. Redwan, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Contemporary research has found that people with autism spectrum disorder (ASD) exhibit aberrant immunological function, with a shift toward increased cytokine production and unusual cell function. Microglia and astroglia were found to be significantly activated in immuno-cytochemical studies, and cytokine analysis revealed that the macrophage chemoattractant protein-1 (MCP-1), interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), and transforming growth factor β-1 (TGFB-1), all generated in the neuroglia, constituted the most predominant cytokines in the brain. Taurine (2-aminoethanesulfonic acid) is a promising therapeutic molecule able to increase the activity of antioxidant enzymes and ATPase, which may be protective against aluminum-induced neurotoxicity. …

Pre-Molten, Wet, And Dry Molten Globules En Route To The Functional State Of Proteins, Munishwar Nath Gupta, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Transitions between the unfolded and native states of the ordered globular proteins are accompanied by the accumulation of several intermediates, such as pre-molten globules, wet molten globules, and dry molten globules. Structurally equivalent conformations can serve as native functional states of intrinsically disordered proteins. This overview captures the characteristics and importance of these molten globules in both structured and intrinsically disordered proteins. It also discusses examples of engineered molten globules. The formation of these intermediates under conditions of macromolecular crowding and their interactions with nanomaterials are also reviewed.

LF3872 was isolated from the milk of a healthy lactating and breastfeeding woman. Earlier, the genome of LF3872 was sequenced, and a gene encoding unique bacteriocin was discovered. We have shown here that the LF3872 strain produces a novel thermolabile class III bacteriolysin (BLF3872), exhibiting antimicrobial activity against antibiotic-resistant Staphylococcus aureus strains. Sequence analysis revealed the two-domain structural (lysozyme-like domain and peptidase M23 domain) organization of BLF3872. At least 25% residues of this protein are expected to be intrinsically disordered. Furthermore, BLF3872 is predicted to have a very high liquid-liquid phase separation. According to the electron microscopy data, the bacterial …

Liaisons Dangereuses: Intrinsic Disorder In Cellular Proteins Recruited To Viral Infection-Related Biocondensates, Greta Bianchi, Stefania Brocca, Sonia Longhi, Vladimir N. Uversky

Molecular Medicine Faculty Publications

Liquid–liquid phase separation (LLPS) is responsible for the formation of so-called membrane-less organelles (MLOs) that are essential for the spatio-temporal organization of the cell. Intrinsically disordered proteins (IDPs) or regions (IDRs), either alone or in conjunction with nucleic acids, are involved in the formation of these intracellular condensates. Notably, viruses exploit LLPS at their own benefit to form viral replication compartments. Beyond giving rise to biomolecular condensates, viral proteins are also known to partition into cellular MLOs, thus raising the question as to whether these cellular phase-separating proteins are drivers of LLPS or behave as clients/regulators. Here, we focus on …

Transcription factor CP2c (also known as TFCP2, α-CP2, LSF, and LBP-1c) is involved in diverse ubiquitous and tissue/stage-specific cellular processes and in human malignancies such as cancer. Despite its importance, many fundamental regulatory mechanisms of CP2c are still unclear. Here, we uncover an unprecedented mechanism of CP2c degradation via a previously unidentified SUMO1/PSME3/20S proteasome pathway and its biological meaning. CP2c is SUMOylated in a SUMO1-dependent way, and SUMOylated CP2c is degraded through the ubiquitin-independent PSME3 (also known as REGγ or PA28)/20S proteasome system. SUMOylated PSME3 could also interact with CP2c to degrade CP2c via the 20S proteasomal pathway. Moreover, precisely …
