Parvalbumin Interneuron-Oligodendrocyte Interactions In The Infralimbic Cortex Promote Extracellular Plasticity Mechanisms After Safety Learning, Lucy Emma Denholtz

Dissertations, Theses, and Capstone Projects

The ability to differentiate between threat and safety cues is essential for adaptive behavior, yet this process is disrupted in psychiatric disorders, such as post-traumatic stress disorder (PTSD), where safety cues fail to downregulate fear expression. To better understand the neurobiological mechanisms of safety learning, I investigate how safety conditioning vs contextual fear conditioning modify behavioral and cellular mechanisms in the infralimbic (IL) region of the medial prefrontal cortex (mPFC) at several time points after learning. Through this work, I identify a novel mechanism whereby safety learning promotes learning dependent neuro-glial interactions that promote conditions for plasticity in the mPFC. …

Individual, Social, And Environmental Factors Associated With Patterns Of Parasitic Infection In Capuchin Monkeys (Cebus Imitator), Megan C. Henriquez

Dissertations, Theses, and Capstone Projects

Parasites, and the infectious diseases they carry, are thought to have significantly impacted our evolutionary trajectory for millennia. Exploring how parasites are acquired and transmitted by their hosts in wild, natural populations is integral to understanding how similar processes may have shaped host-parasite co-evolutionary relationships over time. However, parasitological studies in humans and in non-human primates have produced inconsistent results, highlighting the dynamic, nuanced, and unique relationships individual parasites have with their hosts. These relationships are largely regulated by variation in factors at host, social, and environmental levels. Characteristics unique to the host (e.g., age and sex), factors pertaining to …

Basal Autophagy Promotes Accurate Chromosome Segregation In Drosophila Oocytes And Declines During Oocyte Aging, Diana C. Hilpert

Dartmouth College Ph.D Dissertations

The frequency of trisomic pregnancies exponentially increases with advanced maternal age, a phenomenon known as the maternal age effect. The majority of these aneuploid pregnancies arise from meiotic segregation errors in the oocyte and premature loss of sister chromatid cohesion is a contributing factor. However, the mechanisms that lead to premature cohesion loss during oocyte aging are not fully understood.

Using Drosophila melanogaster as a model organism, work described in this dissertation demonstrates that basal levels of autophagy, a degradation process for damaged organelles and protein aggregates, are required during meiotic prophase for arm cohesion maintenance and accurate meiotic segregation …

Belowground Biomass Shifts Along A Temperate Forest Edge, Lara Holbrook Roelofs

Dartmouth College Undergraduate Theses

Anthropogenic land use change and development has caused widespread global forest fragmentation, resulting in a greater proportion of forests at or near a forest edge. Temperate forests are the most fragmented forest biome, and forests in the Northeastern U.S. are particularly fragmented due to a history of intense land use and development pressure. Nearly a quarter of these forests are now within 30 meters of a forest edge. These edge ecosystems have distinct abiotic and biotic gradients that differentiate them from forest interiors, including increased light, temperature, and exposure to wind and other disturbances, as well as decreases in humidity …

A Scan Of Pleiotropic Immune Mediated Disease Genes Identifies Novel Determinants Of Baseline Fviii Inhibitor Status In Hemophilia A, Marcio Almeida, Vincent P. Diego, Kevin R. Viel, Bernadette W. Luu, Eron G. Manusov, Juan M. Peralta, Satish Kumar, Sarah Williams-Blangero, John Blangero, Tom Howard

School of Medicine Publications

Hemophilia-A (HA) is the X-linked bleeding disorder caused by heterogeneous factor (F)VIII gene (F8)-mutations and deficiencies in plasma-FVIII-activity that prevent intrinsic-pathway mediated coagulation-amplification. Severe-HA patients (HAPs) require life-long infusions of therapeutic-FVIII-proteins (tFVIIIs) but ~30% develop neutralizing-tFVIII-antibodies called “FVIII-inhibitors (FEIs)”. We investigated the genetics underlying the variable risk of FEI-development in 450 North American HAPs (206 and 244 respectively self-reporting black-African- or white-European-ancestry) by analyzing the genotypes of single-nucleotide-variations (SNVs) in candidate immune-mediated-disease (IMD)-genes using a binary linear-mixed model of genetic association with baseline-FEI-status, the dependent variable, while simultaneously accounting for their genetic relationships and heterogeneous-F8-mutations to …

Genetic Analysis Of Psychosis Biotypes: Shared Ancestry-Adjusted Polygenic Risk And Unique Genomic Associations, Cuihua Xia, Ney Alliey Rodriguez, Carol A. Tamminga, Matcheri S. Keshavan, Godfrey Pearlson

School of Medicine Publications

The Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) created psychosis Biotypes based on neurobiological measurements in a multi-ancestry sample. These Biotypes cut across DSM diagnoses of schizophrenia, schizoaffective disorder, and bipolar disorder with psychosis. Two recently developed post hoc ancestry adjustment methods of Polygenic Risk Scores (PRSs) generate Ancestry-Adjusted PRSs (AAPRSs), which allow for PRS analysis of multi-ancestry samples. Applied to schizophrenia PRS, we found the Khera AAPRS method to show superior portability and comparable prediction accuracy as compared with the Ge method. The three Biotypes of psychosis disorders had similar AAPRSs across ancestries. In genomic analysis of Biotypes, 12 genes, …

Insights Into Prey Handling And Feeding Strategies By Ghost Crabs On Sea Turtle Eggs And Hatchlings, Casper Avenant

Research outputs 2022 to 2026

The feeding behaviour on sea turtle eggs and hatchlings by the golden ghost crab Ocypode convexa, a species endemic to the west coast of Australia, was observed in field and laboratory settings using infrared videography. On beaches where ghost crab densities are high, multiple crabs can feed on nests over several nights, often resulting in destruction of clutches. Crabs appear to anticipate the emergence of hatchlings, often congregating near nests in the moments prior to emergence. When feeding on eggs crabs rupture eggshells using the sharp tips of their claws, with tissue subsequently moved to the mouthparts for ingestion using …

Does Pollination By Non-Flying Mammals Contribute Substantially To Fruit Set Of Banksia (Proteaceae)? A Test In Four Species With Contrasting Floral Traits, Stanislaw K. Wawrzyczek, Robert A. Davis, Siegfried L. Krauss, Susan E. Hoebee, Ryan D. Phillips

Research outputs 2022 to 2026

Pollination by non-flying mammals (NFMs) is thought to be associated with cryptic, dull coloured, strongly scented flowers. In Western Australia, various Banksia species exhibit these traits, suggesting adaptation to primary pollination by NFMs, particularly the marsupial honey possum (Tarsipes rostratus). Here, we compare floral visitation rates and assess contribution to fruit set of NFMs and other pollinators in four species of Banksia with contrasting floral traits. Camera trap-based surveys revealed that honeyeater birds visited all species equally and were more frequent visitors than NFMs to the brightly coloured, unscented flowers of B. sessilis and B. splendida. By contrast, NFMs were …

Integrating High Throughput Phenotyping Approaches To Characterize Plant Traits And Support Nutrient Management Research, Katie J. Bathke

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Over the past decade, considerable research has addressed the social, economic, and agronomic challenges posed by imbalanced nutrient applications, particularly nitrogen and, more recently, sulfur. In response, high throughput plant phenotyping, as one of the latest approaches, has contributed to the development of innovative techniques for assessing key plant phenotypes under stress over time in both field and greenhouse environments. However, there is a limited number of studies applying these techniques for nutrient management, particularly in scenarios where two abiotic stressors coexist, such as the combination of water stress and nitrogen deficiency, or concurrent nitrogen and sulfur deficiencies.

Faculty, Staff and Student Publications

DNA methylation alterations, including hypermethylation and silencing of tumor suppressor genes, contribute to cancer formation and progression. The FDA-approved nucleoside analogs azacytidine and decitabine are effective demethylating agents for hematologic malignancies but their general use has been limited by their toxicity and ineffectiveness against solid tumors. GSK-3484862, a dicyanopyridine-containing, DNMT1-selective inhibitor and degrader, offers a promising lead for developing novel demethylating therapeutics. Here, we demonstrate that GSK-3484862 treatment upregulates DNMT3B expression in lung cancer cell lines (A549 and NCI-H1299). Disrupting DNMT3B in NCI-H1299 sensitizes these cells to GSK-3484862, enhancing its inhibitory effects on cell viability and growth. GSK-3484862 treatment induces …

Bile Acid Regulation Of Xenobiotic Nuclear Receptors On The Expressions Of Orosomucoids In The Liver, Ji Ho Suh, Inyoung Cheon, Hyun-Jung Jung, Sung Ho Lee, Mi Jeong Heo, Matthew Deberge, Clavia Ruth Wooton-Kee, Kang Ho Kim

Children’s Nutrition Research Center Staff Publications

The constitutive androstane receptor (CAR) and pregnane X receptor (PXR) are xenobiotic nuclear receptors activated by various xenobiotics, drugs, hormones, and bile acids (BAs). Upon activation, these nuclear receptors play critical roles in regulating systemic energy homeostasis. However, precise mechanisms through which CAR and PXR influence systemic metabolism remain incompletely understood. Here, we investigated the impact of CAR and PXR on the liver-secreted hormone (i.e., hepatokine) expressions in response to BA stress such as cholic acid (CA) feeding. Our analysis revealed that several BA-activated genes, including the well-known CAR/PXR target, aldo-keto reductase family 1, member B7 (Akr1b7 …

Elucidating The Roles Of Eukaryotic Initiation Factors Involved In Dap5 Mediated Translation, Jacob Nk Quartey

Dissertations, Theses, and Capstone Projects

Translation initiation in eukaryotes is a highly regulated process essential for accurate protein synthesis. It is a dynamic process that involves a complex interplay between messenger RNAs (mRNAs), ribosomal subunits, and a host of initiation factors, ensuring precise start codon selection and the subsequent assembly of the translation machinery. This process has well been known to be mediated by the eukaryotic Initiation Factor (eIF4F), which consists of the cap binding protein eIF4E, the scaffolding protein eIF4GI, and the helicase factor eIF4A.The recognition and binding of eIF4E to the m⁷G cap structure of the mRNA is essential for the …

The Sub-Syllabic Symphonies Of Self-Learning: How Do Zebra Finches Sing Them?, Abiesha Abiola Budiman

Dissertations, Theses, and Capstone Projects

Learning is a lifelong journey, where the mind and muscle dance to a tune of memory and motion. It begins at infancy and continues throughout life, encompassing everything from singing to achieving peak performance in sports. Complex motor skills involve multiple components and require coordination of several muscles. Humans and animals are extremely adept at learning complex motor skills on their own. However, we do not completely understand how self-directed learning works. One group of animals used to observe self-directed learning are songbirds. Zebra finches, Taeniopygia guttata, are one of the most studied songbird species due to their well-defined …
