Proline To Serine Mutation In The Active Site Loop Of Malate Dehydrogenase Alters Substrate Specificity, Olivia J. Schmitt

Chemistry & Biochemistry Student Scholarship

Cancer cells preferentially undergo glycolysis in aerobic environments, a phenomenon termed the Warburg effect. Malate dehydrogenase (MDH) catalyzes the reversible interconversion of malate and oxaloacetate. Human cytosolic malate dehydrogenase (hMDH1) isoform 3 is involved in the malate-aspartate shuttle (MAS), which oxidizes cytosolic NADH. hMDH1 is implicated in high aerobic glycolysis in cancer cells because NAD is a necessary cofactor for glycolysis. Thus, hMDH1 is a promising molecular target for cancer treatment. A single proline residue at position 110 in the mobile active site loop of hMDH1 was mutated to a serine with the intention of altering the enzyme’s substrate specificity. …

Development And Kinetic Survey Of A G148t Mutant Human Cytosolic Malate Dehydrogenase Isoform 3 Enzyme With Oxaloacetate And A-Ketoglutarate, Ethan N. Dionne

Chemistry & Biochemistry Student Scholarship

Cancer cells often use an altered metabolic pathway in which glycolysis, uncoupled from the citric acid cycle, serves as the primary source of ATP. To support cancer cell proliferation and growth, the glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) must have a constant source of NAD. While lactate dehydrogenase (LDH) in its conversion of pyruvate to lactate is a well-known source of cytosolic NAD for GAPDH activity, cytosolic malate dehydrogenase (MDH1) also plays a role in cell proliferation through its generation of cytosolic NAD by the conversion of OAA to malate. This development has implicated MDH1 in cancer cell metabolism and characterizing …

From River To Ridge: The Influence Of Elevation And Habitat On Herpetofauna Species Abundance And Diversity In The Llanganates-Sangay Ecological Corridor, Ecuador, Elle Hankin

Independent Study Project (ISP) Collection

Ecuador is one of the most reptile-diverse countries and is home to the highest abundance of amphibians per unit area, with new species being discovered frequently. The Río Pastaza basin is located to the east of the Andes and is characterized by a steep elevational gradient, converging tropical forest types, and high levels of biodiversity and endemicity. Visual surveying was conducted at night for a total of 48 hours in four different study sites to investigate the influence of elevation and habitat on herpetofauna diversity and abundance. Two comparisons were drawn between the four study sites, grouping SKIS and Waska …

The Relationship Between Substrate Composition, Community Structure And Feeding Preferences Of Parrot Fishes (Scaridae) In Anmardub, Guna Yala Coastal Reefs, Caitlin Amman

Independent Study Project (ISP) Collection

Coral reefs are important marine ecosystems, as they support biodiversity and generate buffer zones, yet their abundance is incredibly limited globally. One of the main threats that coral reefs face is excessive macroalgal coverage, which limits sunlight from reaching corals, and thus, limits the energy that can reach them. Parrot fish (Scaridae) are keystone herbivores, as they consume macroalgae growing on corals, which aids in reef survivability. While there is previous research on the abundances, sizes, and feeding habits of Scaridae species in the Caribbean, there is no published research on how community structure and feeding preferences of parrot fishes …

Variation In Student Perceptions Of Higher Education Course Quality And Difficulty As A Result Of Widespread Implementation Of Online Education During The Covid-19 Pandemic, Joseph Cavanaugh, Stephen J. Jacquemin, Christine Junker

Biological Sciences Faculty Publications

The onset of the COVID-19 global pandemic affected higher education in a myriad of ways. One of the most notable effects however was the rapid and sudden transition of nearly all courses at most institutions to an online environment. And while there are a growing number of courses offered online already, this transition to nearly 100% remote education presented numerous challenges for instructors and students of face-to-face and hybrid style courses. Since student perceptions are closely tied to recruitment and retention, it is important to know if there are differences in student perceptions present in the way different courses are …

The Development Of Inhibitors For Sars-Cov-2 Orf8, My Thanh Thao Nguyen

CSB and SJU Distinguished Thesis

An unexpected outbreak of SARS-CoV-2 caused a worldwide pandemic in 2020. Many repurposed drugs were tested, but there are currently only three FDA approved antivirals (Merck’s antiviral Molnupiravir, Pfizer’s antiviral Paxlovid, and Remdisivir).1 Most of the antiviral drugs tested SARS-CoV-2 main protease and RNA-dependent RNA polymerase. However, it is important to explore different drug targets of SARS-CoV-2 to prepare for the virus mutations of the future. This research looks at an alternative approach in which SARSCoV- 2 Open Reading Frame 8 (ORF8), which has been shown to be a rapidly evolving hypervariable gene, was chosen to be the protein of …

Sars-Cov-2 Main Protease Inhibitors Repurposed For Hiv-1 Protease Binding, Jacob Minkkinen

CSB and SJU Distinguished Thesis

Severe acute respiratory syndrome (SARS-CoV-2) led to the COVID-19 global pandemic, with over 460 million cases of infection and over 6 million deaths since the start of the pandemic. SARS-CoV-2 is a retrovirus that utilizes a main protease (Mpro). Mpro is a catalytic cys/his protease. Several treatments were proposed to stop the pandemic including repurposing drugs to inhibit the Mpro. Another retrovirus that uses a protease is human immunodeficiency virus (HIV-1) which has been a global epidemic for 40 years and is a devastating disease that attacks the immune system. HIV-1 has infected 79.5 million people and has killed an …

The Effect Of Gallate Esters On T Cell Immunity, Brianna Cervantes

Longwood Senior Theses

Parabens are used to prevent bacterial growth and are commonly found in cosmetics and personal care products. The structure of parabens is similar to estrogen and can cause increased estrogen activity which unfortunately has been linked to breast cancer. Parabens are endocrine disrupting compounds, which means they disrupt many hormone-regulated systems and could contribute to immune dysfunctions, reproductive disorders, birth defects, or developmental and behavioral disorders. One example of an effect on the immune system is that estrogen regulates CD4 T cell differentiation during pregnancy to induce anti-inflammatory Th2 and Treg phenotypes and reduce the differentiation of inflammatory Th1 and …

The Effects Of Impaired Water On Zebrafish Muscle Development And Startle Responses, Cecily Hayek

Longwood Senior Theses

For over 100 years, the presence of coliform bacteria in water has been used as environmental risk indicators for the occurrence of human pathogens (Salmonella, enteric viruses, etc.). Although these measurements typically are used to protect humans from potential exposure to toxins, little has been researched about the effect on organisms that live in these waters. Our current study utilizes a long-term water monitoring program within the Appomattox River watershed of south-central Virginia, as it examines the effect of raw water containing varying bacteria levels on the first 72 hours of aquatic vertebrate development, using a zebrafish model. Water samples …

Costimulatory Domains Alter The Efficacy And Safety Of Chimeric Antigen Receptor-Expression Gamma Delta T Cells, Stephanie Willis

Longwood Senior Theses

Engineering T cells with a chimeric antigen receptor (CAR) recognizing proteins specifically expressed on tumor cells is a new cancer therapy. While CAR T cells can successfully treat hematopoietic malignancies, CAR T cells have not shown success in treating solid tumors. In addition, one side effect observed after CAR T cell infusion is Cytokine Release Syndrome (CRS) which causes damaging inflammation. There are many factors that may enhance CAR T cell efficacy and safety for solid tumor treatment, including costimulatory domains to increase T cell functions and switching T cell type from alpha beta to gamma delta T cells. We …

Macrophyte Abundance And Nitrate Dynamics Of Silver Bow Creek, Katelyn Reichle

Graduate Theses & Non-Theses

Butte, Montana has an extensive mining history contributing to the contamination degradation of terrestrial and aquatic systems, amongst Silver Bow Creek (SBC). The contamination of the stream and the floodplain created a toxic environment that could not support aquatic life. Although the remediation of the floodplain was successful in removing metal contamination, the recovery of the ecosystem from both the initial pollution and subsequent remediation is ongoing. SBC has also been impacted by the urbanization of Butte, leading to multidimensional ecological disruption. The stream is currently subject to nutrient loading by nitrate, nitrogen, and phosphorus. A possible effect of nutrient …

The Roles Of Individual Proteins In De Novo Recruitment Of Pcg Repressive Complexes To Giant, Anni Kum

Biological Sciences Theses and Dissertations

Epigenetic gene regulation is the process by which external factors regulate the genome. This research studies Polycomb Group (PcG) proteins which function as epigenetic agents that work together in complexes to maintain gene silencing for multiple cellular generations. Drosophila melanogaster PcG proteins can be organized into three canonical complexes: Pho-RC, PRC1, and PRC2. Though there are multiple proposed models for the order of recruitment, it is generally accepted that PhoRC, PRC1, and PRC2 interact with each other to stably recruit to a target gene. Since these proteins are highly conserved, this project studies PcG proteins in the model organism, Drosophila …

Value-Added Opportunities For Tomato And Peach Seeds, Valerie Michelle Lavenburg

Master's Theses

The food industry is increasingly concerned with operational sustainability and food waste reduction. In the United States, the tomato industry was worth $1 billion in 2020, and tomatoes are currently ranked second as the most consumed vegetable after potatoes. Tomato processors have striven to valorize pomace by-products, which contain seeds with valuable compounds such as 45% fiber, 30% oil, and 26% protein. The U.S. peach industry, which was worth $599 million in 2017, is also looking for alternative ways to utilize their seeds, made up of 52% oil. Both tomato and peach seeds are rich in bioactive compounds such as …

Influence Of Soil And Land Cover On Chronic Wasting Disease Prevalence In White-Tailed Deer And Mule Deer Across North America, Madison L. Miller

Masters Theses

Chronic wasting disease (CWD) is a fatal neurodegenerative disease that infects deer and is caused by a pathogenic prion. CWD is a concerning wildlife disease because it is incurable, potentially poses a risk to human health, and is spreading rapidly. CWD prions are transmitted both directly via bodily fluids and indirectly through environmental reservoirs such as soil. In this study, we investigated the influence of land cover and soil characteristics on CWD prevalence in white-tailed deer and mule deer. We acquired CWD prevalence data from seven North American regions and used ArcGIS to obtain land cover and soil characteristic data …

Characterization of the genetic landscape of Alzheimer's disease (AD) and related dementias (ADD) provides a unique opportunity for a better understanding of the associated pathophysiological processes. We performed a two-stage genome-wide association study totaling 111,326 clinically diagnosed/'proxy' AD cases and 677,663 controls. We found 75 risk loci, of which 42 were new at the time of analysis. Pathway enrichment analyses confirmed the involvement of amyloid/tau pathways and highlighted microglia implication. Gene prioritization in the new loci identified 31 genes that were suggestive of new genetically associated processes, including the tumor necrosis factor alpha pathway through the linear ubiquitin chain assembly …

Nectar Source Preferences Of The Hummingbird: A Field Study From South Texas, Jasmine Benavidez

Honors Theses

With the rise of urbanization, comes a rise in urban-like activities—most notable is birdfeeding. Given the increasing popularity of bird-feeding, especially in hummingbird feeding, concern for implications, if any, has mounted. There is reason to believe that artificial feeders can impact the surrounding environment; that is, it is possible that feeders could attract pollinators away from flowering plants, which, in turn, could bring repercussions for pollination and all associated with it. However, literature, on the matter, is rather limited. To add to this, past studies provide two opposing arguments. This study aims to explore the nectar source preferences of hummingbirds …

Impacts Of Land-Use Change And Urban Development On Carbon Sequestration In Tropical Seagrass Meadow Sediments, Martin Dahl, Rashid Ismail, Sara Braun, Pere Masqué, Paul S. Lavery, Martin Gullström, Ariane Arias-Ortiz, Maria E. Asplund, Andrius Garbaras, Liberatus D. Lyimo, Matern S.P. Mtolera, Oscar Serrano, Chanelle Webster, Mats Björk

Research outputs 2022 to 2026

Seagrass meadows store significant carbon stocks at a global scale, but land-use change and other anthropogenic activities can alter the natural process of organic carbon (Corg) accumulation. Here, we assessed the carbon accumulation history of two seagrass meadows in Zanzibar (Tanzania) that have experienced different degrees of disturbance. The meadow at Stone Town has been highly exposed to urban development during the 20th century, while the Mbweni meadow is located in an area with relatively low impacts but historical clearing of adjacent mangroves. The results showed that the two sites had similar sedimentary Corg accumulation rates (22–25 g m−2 yr−1) …

Resisting The Western Scientist Inside And Outside Of The Collegiate Biology Classroom, Dulce G. Ventura , '22

Senior Theses, Projects, and Awards

In this thesis, I explore how conceptions of western science and scientists invade the Swarthmore Biology department and how it impacts BIPOC students inside and outside the classroom. The findings indicate that BIPOC students are routinely harmed by many ideas conceived from colonialism. However, both students and faculty demonstrate resistance inside and outside the classroom. Inside the classroom, faculty members build strong relationships with students in small communities and negate Western science's claim of objectivity. Outside of the classroom, programs like the Biology Big Sibling-Little Sibling program are recentering BIPOC students and their lived experiences, effectively creating a community where …

The Yeast Glucose Sensing Receptor Is Stabilized By Interaction With Casein Kinases, Emma E. Mohler

Senior Honors Theses

Many metabolic diseases are rooted in the inability to process glucose or regulate its uptake. These processes can be explored using yeast as a model. Rgt2 is a glucose sensing receptor in yeast, and it detects glucose concentration outside the cell. This receptor is present on the plasma membrane in high glucose conditions but absent in low glucose. Western blot and a yeast two-hybrid assay were used to investigate the relationship between Rgt2 and the plasma membrane-tethered yeast casein kinases, Yck1 and Yck2. This research demonstrated that in high glucose, Rgt2 is stabilized on the plasma membrane by interaction with …

An Overview Of The Forensic Analysis And Use Of Non-Human Dna, Kaelyn Long

Senior Honors Theses

DNA is present in every living organism on Earth. DNA is also present in a few non-living biological agents such as DNA-containing viruses, and is additionally unique to particular groups of organisms and often even to individuals. This characteristic allows DNA to be quite useful in forensic investigations. This study takes an in-depth look at the forensic use of non-human DNA. DNA analysis is a key component of many forensic investigations, but the majority of these analyses are focused on human DNA. This review examines the ways in which non-human DNA can be useful to forensic investigations. The various unique …

Sars-Cov-2 Reveals That Chimeric Agents Are The Bioweapons Of The Future, Rachel Craig

Senior Honors Theses

Bioweapons programs have existed since their development during the Cold War. These biowarfare programs initially utilized naturally occurring pathogens capable of infecting crops, livestock populations, and human populations. Anthrax is a widely exploited bioagent responsible for attacks ranging from the Germans’ deployment in World War I to the mailing of anthrax through the postal service in attempts on U.S. senators’ lives. With the development of genetic manipulations, the Soviet Union began modifying anthrax to resist detection and treatment. With the continued advancement of science and technology, a new bioagent has entered the scene – the man-made chimeric virus. Chimeric viruses …
