Investigation Of Lubricin-Stimulating Fda-Approved Compounds For A Disease-Modifying Osteoarthritic Drug, Swathi S. Menon Jan 2025

Investigation Of Lubricin-Stimulating Fda-Approved Compounds For A Disease-Modifying Osteoarthritic Drug, Swathi S. Menon

Honors Undergraduate Theses

Osteoarthritis (OA) is a degenerative disease that affects many people worldwide. Current methods of treatment are palliative, and no treatment exists to fully reverse or cure OA once it begins to progress. The discovery of a disease-modifying osteoarthritic drug (DMOAD) would increase the quality of life for millions and reduce the need for invasive procedures. Screening FDA-approved drugs ensures more promise due to their known safety profile and potential for faster translation to the clinic. The goal of this project was to conduct dose-response assays with FDA-approved drugs that have been shown to stimulate lubricin production in cells that mimic …


Development Of A Proposed Selective Medium For The Isolation And Differentiation Of P. Sordellii, Dimyana Bottros Jan 2025

Development Of A Proposed Selective Medium For The Isolation And Differentiation Of P. Sordellii, Dimyana Bottros

Honors Undergraduate Theses

Clostridium, a genus of anaerobic, spore-forming bacteria, includes clinically and ecologically significant species like Clostridium difficile and Paeniclostridium sordellii. C. difficile causes antibiotic-associated colitis, while P. sordellii is linked to fatal infections and spontaneous abortions. Recent studies found both species in marine sediments, suggesting their role in environmental and wildlife health disturbances, including the 2013 mass mortality of over 300 manatees in the Indian River Lagoon. However, isolating and differentiating P. sordellii is challenging due to the lack of selective media optimized for its growth. This thesis proposes a novel selective medium tailored to P. sordellii’s physiological …

The isolation of tick-borne relapsing fever (TBRF) spirochetes has proven to be a useful tool to understand their distribution in geographic areas where the tick vectors inhabit. However, their isolation and culture are not easy and in general an animal model is needed to achieve this task. Here, argasid ticks were collected from a neighborhood in Ciudad Caucel, and they were identified as Ornithodoros (Alectorobius) puertoricensis. To determine whether these were infected with TBRF bacteria they were fed with healthy mice but only a low burden of spirochetes was observed. An immunosuppressed mouse model was used to feed the ticks …

Olfactory sensory neurons within the nasal epithelium detect volatile odorants and relay odor information to the central nervous system. Unlike other sensory inputs, olfactory sensory neurons interface with the external environment and project their axons directly into the central nervous system. The use of adeno-associated viruses to target these neurons has garnered interest for applications in gene therapy, probing olfactory sensory neuron biology, and modeling disease. To date, there is no consensus on the optimal AAV serotype for efficient and selective transduction of olfactory sensory neurons

Parkinson's disease (PD), a progressive neurodegenerative disorder, manifests with motor and non-motor symptoms. Despite similar incidence, in the US, disease management of Hispanic patients with PD is poorer than that of White non-Hispanics, and their participation in clinical trials does not reflect expected values (well below 5% vs. expected values around 20%). Together with other evidence, these observations are expressions of poor healthcare in Hispanic patients with PD, suggesting underutilization of proper healthcare, social and economic disadvantage, and other factors. The scant participation of Hispanic patients in clinical trials further exacerbates care inadequacy. In this paper, after reviewing evidence of …

Markey Cancer Center Faculty Publications

Osteosarcoma (OS) is a relatively rare bone malignancy that primarily affects children and young adults and is associated with significant morbidity and mortality. Cisplatin is a mainstay of treatment, but its efficacy is limited by off-target toxicities. Immunotherapy is not effective due to a poor antigenic tumor microenvironment. Here, we address these challenges by using manufactured M1 macrophage-derived vesicles (MVs) loaded with cisplatin. Human blood and mouse RAW 264.7 M1 macrophages were used to prepare empty (E-MVs) and cisplatin-loaded MVs (C-MVs). Human OS cell lines were used in vitro and in a tibia xenograft mouse model to evaluate the anti-cancer …

School of Medical Diagnostics & Translational Sciences Publications

The mammary microenvironment has been shown to suppress tumor progression by redirecting cancer cells to adopt a normal mammary epithelial progenitor fate in vivo. However, the mechanism(s) by which this alteration occurs has yet to be defined. Here, we test the hypothesis that mitochondrial transfer from normal mammary epithelial cells to breast cancer cells plays a role in this redirection process. We evaluate mitochondrial transfer in 2D and 3D organoids using our unique 3D bioprinting system to produce chimeric organoids containing normal and cancer cells. We demonstrate that breast cancer tumoroid growth is hindered following interaction with mammary epithelial cells …

UROP Posters

Androgen deprivation therapy (ADT) is a primary treatment strategy for prostate cancer (PCa), yet many tumors eventually develop androgen independence, leading to treatment resistance. To investigate the molecular changes underlying this transition, we analyzed differential gene expression in four androgen-independent (AI) clones derived from the Myc-CaP prostate cancer cell line using RNA sequencing. Gene expression profiles were compared to the parental Myc-CaP line, and differentially expressed genes (DEGs) were identified using DESeq2 and edgeR. The AI clones exhibited significant downregulation of senescence-associated genes, including Ezh2 and lamin B1, suggesting a loss of senescence-related chromatin repression. Additionally, upregulation of Wnt pathway …

Molecular Imaging Of Triple-Negative Breast Cancer: Characterization And Modulation Of The Tumor Microenvironment, Shannon E. Lynch

All ETDs from UAB

Triple-negative breast cancer (TNBC) is an aggressive, heterogeneous subset of breast cancer which currently has no targeted therapies available due to lack of molecular therapeutic targets. Importantly, various radiopharmaceuticals can be imaged via positron emission tomography (PET) to quantify cellular and molecular features of the tumor microenvironment including glucose metabolism, receptor status, and immune activation. Somatostatin receptor subtype 2 (SSTR2) is G-protein coupled receptor overexpressed in neuroendocrine tumors (NETs) which can be imaged and targeted for theranostics via FDA-approved radiotherapy. SSTR2 expression is increased in hormone positive breast cancer but is expressed at low or variable levels in TNBC. However, …

Psychometric Evaluation Of A Novel Measure Of Trauma-Related Cannabis Use To Cope, Sage E. Hawn, Terrell A. Hicks, Christopher Latourrette, Anita Thomas, Daniela Chaname, Sarah Ehlke, Abigail Powers Lott

Psychology Faculty Publications

Background: Posttraumatic stress disorder (PTSD) and cannabis use disorder (CUD) are commonly comorbid and are associated with many negative public health outcomes. One plausible explanation for this comorbidity comes from a self-medication framework, which suggests people use cannabis to cope with PTSD symptoms. Despite theoretical and empirical evidence for PTSD-related cannabis use to cope, no measure of this construct exists.

Objective: We sought to address this gap by developing and validating a novel measure of PTSD-specific cannabis self-medication, which we have termed the Trauma-Related Cannabis Use to Cope (TRCU) questionnaire.

Method: The psychometric properties of the TRCU and how it …

Electrochemical Strategies For Microrna Quantification Leveraging Amplification And Nanomaterials: A Review, Alexander Hunt, Gymama Slaughter

Center for Bioelectronics Publications

MicroRNAs (miRNAs) are small, non-coding RNAs that regulate gene expression and have emerged as critical biomarkers in various diseases, including cancer. Their stability in bodily fluids and role as oncogenes or tumor suppressors make them attractive targets for non-invasive diagnostics. However, conventional detection methods, such as Northern blotting, RT-PCR, and microarrays, are limited by low sensitivity, lengthy protocols, and limited specificity. Electrochemical biosensors offer a promising alternative, providing high sensitivity, rapid response times, portability, and cost-effectiveness. These biosensors translate miRNA hybridization events into quantifiable electrochemical signals, often leveraging redox-active labels, mediators, or intercalators. Recent advancements in nanomaterials and signal amplification …
