Evaluating The Impact Of K135t Mutation On Malate Dehydrogenase Kinetic Activity, Emily Frost, Kaitlyn Mello Apr 2026

Evaluating The Impact Of K135t Mutation On Malate Dehydrogenase Kinetic Activity, Emily Frost, Kaitlyn Mello

Undergraduate Research Symposium (2026- )

Malate Dehydrogenase (MDH) is a key protein in the citric acid cycle; its dysregulation can have catastrophic impacts, such as neurological and metabolic disorders, and various cancers. MDH catalyzes the reversible oxidation-reduction reaction between malate and oxaloacetate, also reducing NAD+ to NADH in the process. The citric acid cycle is one of the central metabolic pathways, connecting to other essential pathways, such as amino acid and fatty acid biosynthesis, highlighting the importance of understanding how MDH works. A key site in MDH is the flexible loop region (amino acids 119-137), responsible for substrate binding, catalysis, and orientation. The flexibility of …

Proline To Serine Mutation In Flexible Loop Region Of Malate Dehydrogenase, Anna Molstad, Hannah Robertson Apr 2026

Proline To Serine Mutation In Flexible Loop Region Of Malate Dehydrogenase, Anna Molstad, Hannah Robertson

Undergraduate Research Symposium (2026- )

Malate Dehydrogenase (MDH) is an essential enzyme that converts malate to oxaloacetate using the reduction of NAD+ to NADH. In humans, MDH plays a role in energy metabolism by catalyzing a key step of the citric acid cycle, important for energy production. Other indirect roles for MDH include gluconeogenesis and reoxidizing NADH from fatty-acid β-oxidation. An important feature of MDH is a flexible loop region that can alter substrate binding and enzyme activity, but its role is not well understood. Our study investigated how Pro123 to Ser (P123S) mutation in the flexible loop region affects MDH function. We hypothesized that …


Evaluating Differences In The Dynamic Growth Patterns Of Cvi And Ler Genetic Strains Of Arabidopsis During Seedling Establishment, Emily Frost Apr 2026

Evaluating Differences In The Dynamic Growth Patterns Of Cvi And Ler Genetic Strains Of Arabidopsis During Seedling Establishment, Emily Frost

Undergraduate Research Symposium (2026- )

Seedling establishment is the process by which seedlings transition from depending on seed nutrients to making their own through photosynthesis. An important aspect is photomorphogenesis, the growth of plants in response to light, transitioning from rapid embryonic stem growth to a slower rate focused on root growth and leaf formation. The process is influenced by many genetic and environmental factors, making better characterization essential to understand plant development. For our research, we examined the dynamic growth of two Arabidopsis genetic strains (Cvi and Ler) over time in response to darkness, then to the change in response when light is introduced. …


Biophysical Insights Into A Cryptic, Hydrophobic Binding Site On Pcna, Alexis Dispensa Apr 2026

Biophysical Insights Into A Cryptic, Hydrophobic Binding Site On Pcna, Alexis Dispensa

Theses and Dissertations

Proteins are dynamic molecules whose functional landscapes extend beyond static structural representations. Transient cryptic pockets (buried cavities that emerge through protein motion) represent underexplored targets for allosteric regulation and drug discovery. General anesthetics are small, lipophilic, weakly polar molecules that are well suited to partition into such hydrophobic sites. In this work, environment-sensitive fluorescence, photoaffinity labeling, mass spectrometry, mutational analysis, and microsecond molecular dynamics simulations were integrated to discover and characterize a cryptic, highly apolar binding site within the hydrophobic core of human proliferating cell nuclear antigen (PCNA), a central scaffold in DNA replication and repair. Using the solvatochromic fluorescent …


The Role Of Pten Subcellular Localization In Neuronal Development And Autism Spectrum Disorder, Nicole Desmet Apr 2026

The Role Of Pten Subcellular Localization In Neuronal Development And Autism Spectrum Disorder, Nicole Desmet

Dartmouth College Ph.D Dissertations

Autism spectrum disorders (ASD) are genetically heterogeneous neurodevelopmental conditions that nevertheless converge on altered neuronal connectivity and circuit function. A central unresolved problem in the field is how diverse genetic perturbations, acting at different biological levels and developmental stages, give rise to shared neurodevelopmental outcomes. This dissertation addresses this problem by examining how gene function, subcellular signaling, and developmental context interact to shape neuronal morphology and circuit-relevant phenotypes.

Cell-autonomous mechanisms regulating neuronal morphology are examined through the ASD risk gene Phosphatase and Tensin Homolog (PTEN) in developing dentate gyrus granule neurons. Selective biasing of PTEN to defined intracellular compartments in …

Evaluating Sand Characteristics And Their Influence On Sea Turtle Nest Incubation Conditions, Thomas Naylor

Honors Theses

The embryonic development of sea turtles is strongly influenced by the environmental factors experienced during incubation within the nest. These environmental factors can influence hatchling sex ratios, body condition, and their success emerging from nests. Adult female sea turtles lay nests across a range of sites throughout the nesting season, resulting in each nest encountering unique abiotic conditions. This study aims to identify how variation in sand characteristics, such as grain size proportions, permeability, and color, influences nest temperature and subsequent hatchling outcomes of Loggerhead Sea Turtles (Caretta caretta) and Green Sea Turtles (Chelonia mydas) from …


Exploring Undergraduate Student’S Perceptions Of Agriculture, Cayden J. Barton Apr 2026

Exploring Undergraduate Student’S Perceptions Of Agriculture, Cayden J. Barton

Honors Theses

Americans today, both young and old, face issues with agricultural knowledge regarding the food and fiber industry and production agriculture as a whole (Frick et al., 1995). In a society where consumers are separated from production agriculture, public interaction with agriculture is less prevalent and the importance of agriculture is undervalued. A person’s knowledge of agriculture, or agricultural literacy affects the way that they perceive agricultural commodities and the agricultural industry (Specht, McKim, & Rutherford, 2014). Without adequate knowledge of the agricultural industry consumers cannot make well informed decisions about food safety or processing methods. In addition to consumers, government …

Socially Constructing ‘Climate Change’ In Fishing Communities Of Sarangani, Philippines, Samantha Geraldine G. De Los Santos, Ma. Larissa Lelu P. Gata

Journal of Public Affairs and Development

The intensifying impacts of climate change have become more evident in recent years. While policies and programs have been implemented in the Philippines for decades, questions remain about how climate change is understood and experienced by fishing communities, the country’s poorest sector. By applying the Ecological-Symbolic Approach, this paper inquired into the fisherfolk’s social definition of climate change. A Qualitatively Driven Sequential Explanatory (QualDSE) mixed-methods design guided the study in developing an informed, substantiated, and context-based definition of climate change. This definition was also analyzed vis-a-vis the widely held definitions in national climate policy.

The terminology “climate change” remains unknown …


The Impact Of Sex Education On College Student’S Perceptions Of Sexual Taboos, Noel Gamon Apr 2026

The Impact Of Sex Education On College Student’S Perceptions Of Sexual Taboos, Noel Gamon

Honors Theses

The purpose of this research is to explore how college students' differing levels of sex education are associated with their views about sexual behavior, particularly behaviors defined as taboo. In comparison to 25 years ago, adolescents are less likely to receive important sex education today; and are unlikely to receive valuable information until after their first sexual experience. Conventionally, the benefits of a sex education program are linked with its ability to lower STI rates, unplanned pregnancies, unwanted behavior, etc. Sexual taboos are sexual practices excluded from the hegemonic heterosexual monogamous relationship model. Presently, society acknowledges a wider range of …


G1p3 Dysregulates Interferon-Stimulated Gene Expression In Er (+) Breast Cancer Cells, Karina Santana Apr 2026

G1p3 Dysregulates Interferon-Stimulated Gene Expression In Er (+) Breast Cancer Cells, Karina Santana

Honors Theses

Even with advances in diagnosis and treatment, breast cancer remains the second leading cause of cancer-related death in women, with nearly 90% of fatalities linked to drug resistance driven by metastasis and recurrence. G1P3, an anti-apoptotic mitochondrial protein, is upregulated in breast cancer and has been associated with increased metastatic potential and poor prognosis. Recent findings show that G1P3 enhances interactions between Rab5-containing endosomes (RCEs) and mitochondria, and emerging evidence suggests that mitochondria play a critical role in initiating interferon (IFN) responses. Based on this, we hypothesized that G1P3-mediated interactions between RCEs and mitochondria promote interferon-stimulated gene (ISG) expression in …

School of Integrative Biological & Chemical Sciences Faculty Publications

The population of the once-endangered brown pelican (Pelecanus occidentalis) has increased over the past several decades and is now considered fully recovered. However, in south Texas, the combined effects of weather patterns, transportation infrastructure, and brown pelican biology have led to road mortalities on State Highway 48 (SH 48) at the Carl “Joe” Gayman Bridge. To mitigate these mortalities, the Texas Department of Transportation modified traffic barriers on SH 48. We aimed to examine the effect of the barrier change and determine which weather variables influence brown pelican groundings on SH 48. Citizen scientists monitored sections of SH …


Dietary Manipulations Of The Undernourished Infant Microbiome, Cyrus Zhou Apr 2026

Dietary Manipulations Of The Undernourished Infant Microbiome, Cyrus Zhou

Arts & Sciences Graduate Student Theses and Dissertations

Today, undernutrition affects approximately 150 million children worldwide. During the first two years of life, the healthy gut microbial community undergoes a series of predictable developmental transitions. These transitions are delayed in undernourished children resulting in microbiota “immaturity.” In a foundational study, immature gut microbial communities from undernourished children and normally developing communities from chronologically age-matched healthy children living in the same area were transplanted into groups of germ-free mice consuming the same diet – one representative of what consumed by the study population. Compared mice with a mature gut microbiome, mice with an immature gut microbiome had impaired weight …


A Computational Assessment Of Halobacterium Salinarum Glutamate Dehydrogenase Enzymes, Maaz Abdalla Apr 2026

A Computational Assessment Of Halobacterium Salinarum Glutamate Dehydrogenase Enzymes, Maaz Abdalla

Thesis/ Dissertation Defenses

Glutamate dehydrogenase (GDH) is a hexameric enzyme. GDH is involved in several pathways and cellular processes such as oxidation-reduction homeostasis, ammonia metabolism, lipid biosynthesis, insulin and lactate production, and acid-base equilibrium. The main objective of this thesis is to understand the structural and biochemical properties of this enzyme and why some organisms, for e.g., Halobacterium salinarum, have more than one GDH with different coenzyme specificities. The catabolism of glutamate is linked to NAD+-specific GDHs, meanwhile, NADP+-specific GDHs play an anabolic role in ammonia assimilation. Molecular docking and binding free energy calculations were employed followed by long-scale (500 nanoseconds) comparative molecular …

Quantitative Proteomics For The Investigation Of Phosphoprotein Phosphatase 1 And 3 Substrate Specificities, Galini Poimenidou Apr 2026

Quantitative Proteomics For The Investigation Of Phosphoprotein Phosphatase 1 And 3 Substrate Specificities, Galini Poimenidou

Dartmouth College Ph.D Dissertations

Reversible phosphorylation is a crucial post-translational modification (PTM) that modulates a variety of signaling pathways intracellularly, with aberrant protein phosphorylation being a hallmark of many human diseases. Kinases, which catalyze phosphorylation of their substrates, have been extensively studied in the context of the signaling pathways they regulate and their effects on cellular processes. In contrast, phosphoprotein phosphatases (PPPs), which catalyze the removal of phosphate groups from substrate proteins, have only recently come to the research spotlight. For a long time, protein phosphatases were deemed unspecific housekeeping enzymes, but they are now known to display exquisite substrate specificity. Phosphoprotein phosphatase 1 …
