Raising Red Flags: Exploring Phenotypic Change In Tiger Moths (Apantesis) Of Coastal Sc Over 50 Years' Time, Allison K. Fletcher

Senior Theses

Organismal phenotypes play a critical role in ecological interactions and individual fitness, and they may undergo rapid shifts through evolutionary adaptation or phenotypic plasticity in response to climate change and environmental disturbances. As morphological traits such as body size, melanization, and aposematic coloration are especially significant for thermoregulation and predator deterrence, it is important to understand the ways in which these traits may be changing on a regional level. Here, I examined the change in phenotype in populations of three tiger moth (Apantesis) species from a single site in coastal South Carolina over a fifty-year period, testing for differences in …

Examining Genomic Islands To Trace The Evolution Of The Urinary Microbiome, Elena G. Renshaw

Senior Theses

There has been a longstanding misconception that the healthy human urinary tract is sterile; however, increasing evidence demonstrates the presence of a dynamic resident urinary microbiota. Emerging research suggests that the urinary microbiota plays a protective role against urological symptoms and infection, but interactions between urinary bacterial species remain understudied. Genomic islands (GIs) are large DNA segments acquired through horizontal gene transfer between bacteria and can provide fitness advantages, particularly to uropathogens. This research utilizes 1,301 genome sequences isolated from urine samples representing the bacterial diversity found within the human urinary tract. GIs were annotated using IslandViewer 4 and TreasureIsland. …

An Analysis Of Vhl And Its Relation To Leukemia, Elaine Vanterpool, Marquise Develde

Student Posters

Leukemia is the cancer of the body’s blood-forming tissues, including the bone marrow and the lymphatic system. Mainly, leukemia effects the white blood cells. The malignancy known as leukemia damages the body's capacity to make healthy blood cells and starts in the bone marrow. White blood cells, which are essential to the immune system, are its main target. Leukemia disrupts normal blood function by causing an aberrant multiplication of immature blood cells, in contrast to other malignancies that create solid tumors. The disease is divided into various categories according to the particular blood cells impacted, and it can develop either …

An Analysis Of Sco2 Variants Associated With Dilated Cardiomyopathy, Elaine Vanterpool, Mitspah Eshette

Student Posters

Dilated cardiomyopathy (DCM) is characterized by severe damage to the heart muscle. The left ventricle becomes enlarged and then thins, causing it to pump with less force than it should. After each beat, more blood remains in the heart, making it challenging for the heart to supply blood to other parts of the body. If the patient is younger than 50, Black, male, and has a family history of dilated cardiomyopathy, they may be at higher risk. DCM has various causes, including coronary artery disease, diabetes, heart attacks, and high blood pressure. However, one of the major causes of DCM …

Combination Of Hdac And Fyn Inhibitors In Synovial Sarcoma, Kyra Parker

Theses

The SS18-SSX fusion protein is an oncogenic driver in synovial sarcoma. At the molecular level, SS18-SSX functions as both an activator and a repressor to coordinate transcription of different genes responsible for tumorigenesis. Here, we identify the proto-oncogene FYN as a new SS18-SSX target gene and examine its relation to synovial sarcoma therapy. FYN is a tyrosine kinase that promotes cancer growth, metastasis and therapeutic resistance, but SS18-SSX appears to negatively regulate FYN expression in synovial sarcoma cells. Using both genetic and histone deacetylase inhibitor (HDACi)-based pharmacologic approaches, we show that suppression of SS18-SSX leads to FYN reactivation. In support …

Proteomic-Based Strategies To Determine Aberrant Signaling In Cancer, Natasha Chipman Mariano

Dartmouth College Ph.D Dissertations

Proteomics and phosphoproteomics have emerged as powerful tools to elucidate the intricate molecular underpinnings that drive cancer development by quantifying changes in protein and post-translational modification abundances. Throughout my thesis work, I have advanced these techniques to map cancer signaling networks on a global scale. Among breast cancer subtypes, triple-negative (TNBC) remains the most challenging to treat, with poorer clinical outcomes attributed to tumor heterogeneity and yet unidentified, oncogenic driver proteins for therapeutic targeting. To identify potential targeted treatment strategies, we employed mass spectrometry-based quantitative proteomics to analyze 55 formalin-fixed paraffin- embedded TNBC tumor specimens. Unsupervised hierarchical clustering of relative …

Hydin Gene Variants: Implications In Primary Ciliary Dyskinesia And Other Diseases, Elaine Vanterpool, Sharie Angus

Student Posters

The HYDIN gene, also known as CILD5, HYDIN1, HYDIN2, and PPP1R31, encodes a protein that plays a role in cilia motility. Mutations in HYDIN are associated with autosomal recessive primary ciliary dyskinesia-5 (PCD5), a disorder characterized by cerebrospinal fluid accumulation in the brain’s ventricles. A duplicate copy of this gene has also been identified on chromosome 1 in humans. Research indicates that HYDIN loss of-function mutations contribute to asthenoteratozoospermia, leading to structural defects in sperm flagella, disassembly of the acrosome and neck, and subsequent male infertility. Intracytoplasmic sperm injection (ICSI) has been proposed as a potential treatment for sperm immobility …
