Investigating The Endogenous & Synthetic Estrogens To The Three Estrogen Receptor Subtypes Of Teleost Fish, Ann Cyril
Posters - 2026
Estrogen and the estrogen receptors are important biological and physiological processes. The various types of estrogen include estrone, estradiol and estriol. Estradiol’s main function is to maintain the reproductive system. Estrone’s main function is to develop the female's reproductive functions. Estriol’s main function is to aid the female's sexual developments but is on the weaker side. The fish, Atlantic Croaker, has three different estrogen receptors: ERα, ERβa, and ERβb. Based on the estrogen receptors, it appears that their binding affinities do differ in strength. Each estrogen receptor has different amino acids involved that could contribute to the difference in their …

Nucleotide Excision Repair In Yeast, Kinleigh Mines, Larry Ramirez, Jacob Rodriguez, Delynda Gonzalez
Posters - 2026
DNA damage occurs constantly in cells due to environmental factors and normal cellular processes, making DNA repair pathways essential for maintaining genomic stability (Hindi et al., 2021). One major repair mechanism is Nucleotide Excision Repair (NER), which is responsible for recognizing and removing bulky DNA lesions that distort the double helix structure (Scharer, 2013). In Saccharomyces cerevisiae (yeast), the RAD14 gene plays a critical role in this pathway by helping identify and initiate repair of damaged DNA (Scharer, 2013). Another source of instability comes from the formation of G-quadruplex (G4) structures, which are secondary DNA configurations that can interfere with …

Cancer remains a leading cause of death worldwide, and childhood sarcomas such as Rhabdomyosarcoma (RMS) and Ewing Sarcoma (ES) are particularly aggressive with limited targeted treatment options. Despite advancements in cancer therapies, metastatic sarcomas still have a survival rate below 30%, emphasizing the need for new therapeutic targets. SOX18, a transcription factor has played a role in vascular development and endothelial differentiation, functioning as a key driver of angiogenesis. In cancer, increased SOX18 expression has been linked to dysregulated cell migration, invasion, and therapy resistance mechanisms. However, the extent to which SOX18 influences RMS and ES at the transcriptional level …

Discovering Drug-Like Compounds By Targeting Protein-Protein Interactions Using A Yeast-3-Hybrid System, Chesley C. Blake
Senior Theses
Protein-protein interactions are important targets in cancer biology as they can make historically “undruggable” proteins viable drug targets. However, the current approach to targeting protein-protein interactions relies on the use of small molecule drugs, which have low efficiencies as they must cover a large surface area of the interaction. Further, traditional drug therapies often lead to off-target toxicity, limiting therapeutic specificity. The objective of this project is to develop a selection system in yeast to identify short peptide sequences that can disrupt protein-protein interactions specific to cancer cells. Following proof of principle and development of the AH109 yeast strain having …

Sustainable Mitigation Of Microplastic Pollutants Using Native Plant Species, Antonio Martinez
Posters - 2026
Microplastics (MPs) are defined as small plastic particles that come from the degradation of plastics [Ziani et al. 2023], that hold a regular or irregular shape, ranging from 1μm to 5 mm [Campanale et al. 2025]. This diminutive size makes them virtually impossible to remove once released into the environment[Lee et al. 2023]. Furthermore, biological, chemical, and physical processes break MP's further down in the environment, causing them to exist in nano-level sizes (1nm-1μm) [Lee et al. 2023], further exacerbating their threat to critical habitats. However, recent studies have shown MP contamination expands beyond the natural environment as recent studies …

Student Papers, Posters & Projects
Glioblastoma multiforme is the most common adult primary tumor with a grim median survival time of 14.6 months. It is characterized by rapid progression, diffuse infiltration, and rather poor clinical outcomes. The WHO classifies GBM as a grade 4 diffuse astrocytic tumor with distinctive histopathological features including high mitotic activity, marked cellular atypia, microvascular proliferation, and necrosis. Advances in molecular diagnostics have further classified GMB into IDH-wild type and IDH-mutant subtypes, with important therapeutic and prognostic implications. Key genetic alterations, such as EGFR amplification, PTEN loss, TP53 mutations, TERT promoter mutations, and MGMT methylations, have been identified as contributing to …

The Role Of Emerin In Myogenic Differentiation, Nicholas Marano
Theses and Dissertations
The nucleus harbors genetic material encapsulated by the nuclear envelope which is composed of an inner and outer nuclear membrane. The establishment and organization of chromatin at the INM is essential for cell fate during the differentiation program. Integral INM proteins are responsible for chromatin organization at the nuclear envelope. Emerin is a highly conserved type II integral INM protein with roles in chromatin organization, cell signaling, and nuclear structure. Mutations in the emerin gene cause Emery Dreifuss Muscular Dystrophy 1 (EDMD1). Emerin is ubiquitously expressed, but loss of emerin function affects specifically skeletal muscle and cardiac tissue. The precise …

Effect Of Novel Antimicrobial Compounds On Fungal And Bacterial Pathogens, Megan Wilderman
Honors Program: Senior Projects (Public)
Antimicrobial resistance is a growing concern in medicine1 leading to a need for the development of novel compounds. Two compounds were tested in this study, 2-hydroxyethylhydrazine (HEH) and para-nitrophenyl-isocyanide (NPIC). HEH targets phosphatidylcholine (PC) production2, and NPIC targets mitochondrial function3. Choline (Cho) is a compound that bypasses the inhibition of HEH through the Kennedy pathway.2 Two-fold serial dilutions were conducted in 96-well plates to test the sensitivity of different bacteria to HEH and fungi to HEH and NPIC in different media types. A choline condition was also included in the HEH dilutions to test …

Characterization And Advancement Of Molluscan Venom Gland Cell Model Systems, James V. Parziale
Dissertations, Theses, and Capstone Projects
Venomous mollusks, including cone snails and coleoid cephalopods, produce rich repertoires of bioactive peptides with profound effects on cellular physiology, yet there are few tractable experimental systems that exist to study their development, maintenance, and venom secretion. Although therapeutics such as the cone snail peptide Ziconotide demonstrate the biomedical potential of molluscan venoms, progress in understanding how venom glands form, function, and evolve has been hindered by the lack of reliable husbandry and the complete absence of in vitro cell models. Modern comparative genomics has revealed widespread convergent evolution across venomous lineages, but molluscan datasets remain underrepresented, limiting insights into …

Dissertations, Theses, and Capstone Projects
Venom peptides represent a natural repertoire of bioactive compounds that are potent modulators of ion channels. Teretoxins, venom peptides from terebrid snails, remain underexplored despite their structural and functional diversity. This thesis is the first to comprehensively explore the structure and function of teretoxins using a comparative computational sequence and structure model followed by experimental assays. The majority of the functional focus has been on identifying the ion channel molecular targets of uncharacterized teretoxins. Teretoxins, like other venom peptides, are hypothesized to manipulate the cellular function of a diversity of ion channels. Dysregulation of ion channels leads to several …

4e-Bp1 Differentially Regulates Translation Of A Subset Of Human Mrnas, Mehreen Mahbub
Dissertations, Theses, and Capstone Projects
Elevated levels of eukaryotic initiation factor 4E-binding protein 1 (4E-BP1) influence cap-independent translation by forming a complex with eukaryotic initiation factor 4E (eIF4E) (eIF4E•4E-BP1). Certain mRNAs—including those encoding hypoxia-inducible factor-1α (HIF-1α), fibroblast growth factor-9 (FGF-9), and two isoforms of tumor suppressors, p53 (p53A, and p53B)—contain structured 5’untranslated regions (UTRs) that enable translation either via cap-independent translation enhancer (CITE)-like or internal ribosomal entry site (IRES)-like mechanisms. However, how 4E-BP1 modulates these mechanisms remains unclear. Using fluorescence-based anisotropy assays, we showed that the eIF4E•4E-BP1 binds more tightly to the 5’ m7G-cap of these mRNAs than eIF4E …

Student Papers, Posters & Projects
Despite significant advancement in cancer treatments, therapies with minimal toxicity to healthy cells are still limited. One targetable weakness of cancer cells is their sensitivity to oxidative stress. We find that the combination of two antioxidants—the common food additive tert-butylhydroquinone (tBHQ) and a manganese porphyrin in clinical trials, MnTnBuOE-2-PyP5+ (MnBuOE)—increases oxidative stress and causes apoptotic death in several cancer cell lines, but not in mouse primary fibroblasts. Investigating the mechanism of cell death, MnBuOE is observed to catalyze the oxidation of tBHQ, producing the electrophilic quinone tert-butylquinone (tBQ). A critical role for tBQ and its electrophilic character was revealed with …

Dapagliflozin (DPG), an anti-diabetic drug, has gained attention for its renal protective effects through multiple molecular pathways, yet its impact on mitophagy in cisplatin (CIS) nephrotoxicity remains unclear. This study aimed to examine the impact of DPG against CIS-induced nephrotoxicity in rats, targeting mainly PINK1/Parkin-mediated mitophagy and inflammatory/apoptotic pathways. Male Sprague Dawley rats received DPG (10 mg/kg; p.o) daily for 14 consecutive days and AKI was induced by a single injection of CIS (7 mg/kg; i.p) on day 10. Blood glucose, serum levels of creatinine and urea nitrogen, oxidative stress, inflammatory, apoptotic, mitophagy markers, and histological changes were assessed. DPG …

RNA-binding proteins (RBPs) with prion-like domains (PrLDs), such as FUS and TDP-43, condense into functional liquids, which can transform into pathological fibrils that underpin fatal neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD). Here, we define short RNAs that prevent FUS fibrillization by promoting liquid phases and distinct short RNAs that prevent and reverse FUS condensation and fibrillization. These activities require interactions with multiple RNA-binding domains of FUS and are encoded by RNA sequence, length, and structure. We define a short RNA that dissolves cytoplasmic FUS aggregates, restores nuclear FUS, and mitigates FUS toxicity in optogenetic models and ALS …

Generating A Gfp Reporter Via Crispr To Visualize Ssa4 Export, Aara Khairollahi, Rebecca Adams
SPARK Symposium Presentations
In eukaryotic cells, the transport of mRNA from the nucleus to the cytoplasm is a very regulated process controlled by nuclear pore complexes (NPCs). During stress conditions, such as heat shock, most mRNA export is inhibited in Saccharomyces cerevisiae, yet the transcript for SSA4, a gene responsible for refolding denatured essential proteins, is exported. The mechanism behind this selective export remains unknown. To investigate this, we used CRISPR-Cas9 to generate a reporter strain in which the SSA4 open reading frame was replaced or inserted with green fluorescent protein (GFP). This reporter is designed to produce GFP only under conditions that …
