The Role Of Sirt7 In Beta Cell Function And Insulin Secretion, Trevor C. Kendrick, Jeffrey S. Tessem, Connor Littlefield Mar 2024

The Role Of Sirt7 In Beta Cell Function And Insulin Secretion, Trevor C. Kendrick, Jeffrey S. Tessem, Connor Littlefield

Library/Life Sciences Undergraduate Poster Competition 2024

Diabetes is a chronic metabolic disease characterized by an inability of beta cells to produce or secrete insulin due to decreasing beta cell mass, a condition induced by beta cell death or overuse. Current treatment consists of daily administration of insulin to diabetic individuals. We have shown that Sirtuin 7 (Sirt7), a deacetylase located in the nucleus, directly interacts with Nkx6.1, a transcription factor essential for beta cell function and proliferation. We have shown that one of the post translational modifications that impinges on Nkx6.1 activity is acetylation. Given Sirt7’s role as a deacetylase, and published reports demonstrating its impact …


Tardigrade Niche Partitioning, Samantha Hougaard, Byron Adams Mar 2024

Tardigrade Niche Partitioning, Samantha Hougaard, Byron Adams

Library/Life Sciences Undergraduate Poster Competition 2024

The two types of Tardigrade (also known as Tardigrade), Ramazzottius and Echiniscus, coexist in the same environment. It could be assumed that they partition their resources by food type to avoid competition. To test this theory, I limited the two tardigrade groups to one food source.


Phylogeny Of Hetaerina (Odonata: Calopterygidae): Settling Taxonomic Issues, Reganne Leigh Hales, Seth M. Bybee, Laura N. Sutherland, Melissa Sanchez Herrera, Samantha Standring Mar 2024

Phylogeny Of Hetaerina (Odonata: Calopterygidae): Settling Taxonomic Issues, Reganne Leigh Hales, Seth M. Bybee, Laura N. Sutherland, Melissa Sanchez Herrera, Samantha Standring

Library/Life Sciences Undergraduate Poster Competition 2024

Recent phylogenetic work within Hetaerininae based on Sanger data highlighted classification issues (e.g., non-monophyly between the genera), however no changes were proposed at that time. We explore the phylogeny of Hetaerininae using a targeted enrichment approach (AHE) of 20KB (18.5KB of nuclear and 1.5 of mitochondrial DNA) in an attempt to resolve any discrepancies.


Achievement Goals And Burnout In Pre-Health Profession Undergraduate Students, Hunter Nelson, Jamie Jensen Mar 2024

Achievement Goals And Burnout In Pre-Health Profession Undergraduate Students, Hunter Nelson, Jamie Jensen

Library/Life Sciences Undergraduate Poster Competition 2024

Oral Presentation Honorable

Relevant Background

• STEM majors are saturated with Pre-health students

• There is high demand for academic excellence and high competition

• Medical school programs (Dyrbye, 2016) and health careers (Shanafelt et al., 2022) show a high rate of burnout

• Symptoms of burnout are mental fatigue, less selfsatisfaction, and depression (Koutsimani, 2021).

• Achievement Goal Theory (AGT) may predict burnout (Nadon et al., 2020).


Understanding The Impact Of Post-Translational Modifications On Nucleosome Positioning, Bronwyn Kennington-Nitz, Steven Johnson, Sophie Lo, Michael Mann, David Bates Mar 2024

Understanding The Impact Of Post-Translational Modifications On Nucleosome Positioning, Bronwyn Kennington-Nitz, Steven Johnson, Sophie Lo, Michael Mann, David Bates

Library/Life Sciences Undergraduate Poster Competition 2024

The placement of histones along DNA is known to be a significant factor in determining gene expression in eukaryotic cells, with post-translational modifications (or PTMs) helping modulate gene expression by acting as an intermediate to other factors. Using the Lys>Gln and Acetyl-Lys mutations of H3, our working hypothesis is that acetylation will decrease the overall strength of positioning, and that mutations will have an identical or nearly identical effect on nucleosome positioning.


Theranostic Approaches To Treat Synovial Sarcoma, Machenzie Burr, Jared Barrott, Jeffrey Okojie, Delaney Anderson, Peyton Worley, Jack Davis, Bridger Kearns, Melanie I'Anson-Holton Mar 2024

Theranostic Approaches To Treat Synovial Sarcoma, Machenzie Burr, Jared Barrott, Jeffrey Okojie, Delaney Anderson, Peyton Worley, Jack Davis, Bridger Kearns, Melanie I'Anson-Holton

Library/Life Sciences Undergraduate Poster Competition 2024

Synovial sarcomas (SS) are rare soft tissue cancers that are found beside bone in children and adolescents. Currently, the prognosis for these diseases are low, as diagnostic and treatment options are limited due to the rarity of the disease. With high rates of metastasis, treatment options for these diseases become further limited to primarily radiation and chemotherapies. These therapies have limited specificity in their mechanisms, causing severe side effects in patients. This work examined alternative options for synovial sarcoma theranostic approaches, specifically using immunoconjugates for Oncostatin M Receptors (OSMR). This receptor was chosen due to the high rate of expression …


Fish Tattoos: The Evolutionary Cost Of Black Spot Disease, Eric J. Morris, Jerry B. Johnson Mar 2024

Fish Tattoos: The Evolutionary Cost Of Black Spot Disease, Eric J. Morris, Jerry B. Johnson

Library/Life Sciences Undergraduate Poster Competition 2024

QUESTION

Does Black Spot Disease increase the fitness of male fishes?

HYPOTHESIS

We hypothesize that Black Spot Disease will increase the fitness of male fishes. We predict that female fishes will exhibit an association preference for infected males over healthy males when given the choice between the two. This observed preference would suggest that BSD is advantageous for male fishes
