The Cold Hard Truth: Cryopreserved Tissue Is Superior To Ffpe Tissue In Molecular Analysis, Delaney Anderson, Jeffrey Okojie, Mackenzie Burr, Peyton Worley, Isaac Parker, Jack Davis, Bridger Kearns, Jared Barrott

Library/Life Sciences Undergraduate Poster Competition 2024

Personalized cancer care requires molecular characterization of neoplasms. While the research community accepts frozen tissues as the gold standard analyte for molecular assays, the source of tissue for all testing of tumor tissue in clinical cancer care comes almost universally from formalin-fixed, paraffin-embedded tissue (FFPE). Specific to genomics assays, numerous studies have shown significant discordance in genetic information obtained from FFPE samples and cryopreserved or flash frozen samples. To explain the discordance between FFPE samples and cryopreserved samples, a head-to-head comparison between FFPE and cryopreserved tissues was performed to analyze the DNA yield, DNA purity and DNA quality in terms …

Library/Life Sciences Undergraduate Poster Competition 2024

The mammalian superior colliculus (SC) and its non-mammalian homolog–the optic tectum (OT)–are midbrain structures that integrate multimodal sensory inputs and guide involuntary movements in response to relevant environmental cues. Recent work has drawn strong connections between the functions of the SC/OT and behavioral deficits observed in autism spectrum disorder (ASD), thus implicating this structure as a possible site affected in ASD. Since fetal exposure to valproic acid (VPA) has been associated with increased prevalence of ASD in humans, and ASD-like phenotypes in animal models, we exposed embryonic zebrafish to VPA to investigate the connection between ASD and OT development.

Library/Life Sciences Undergraduate Poster Competition 2024

Lung cancer is the leading cause of cancer related death in the United States, and non-small cell (NSCLC) is the most common type. An increasingly prevalent treatment in the last few years for NSCLC has been immunotherapy. However, for immunotherapy to be the most effective, we need to have a better understanding of how the immune system interacts with cancer in all stages. Specifically, we need to know where the immune cells reside, how they interact with each other, and how these populations change as the disease progresses. To define the tumor microenvironment, we stained 27 whole tumor slides with …

Changes In Environmental Conditions Affect The Two Isoforms Of Snap-25 Differently, Joseph Jackson, Dixon J. Woodbury, Tanner M. Blocker, Samuel W. Shumway, Jarom S. Sumsion, Thomas Weed, Jason Carlson, Nathan Mumford, Ryan Poland

Library/Life Sciences Undergraduate Poster Competition 2024

In the brain, neurons communicate via releasing and detecting neurotransmitters. Release occurs through exocytosis, following fusion of synaptic vesicles to neuronal cell membranes. This process is driven by formation of a dynamic quaternary protein structure known as the SNARE complex. SNAP-25 contributes two alpha helical domains to this complex. Neurons express SNAP-25 in two distinct isoforms, SNAP-25A (25A) and SNAP-25B (25B). These two isoforms vary by only 9 amino acids and are expressed differently depending on brain region and the developmental stage of the neuron [1]. The primary structures of 25A and 25B and their effect on SNARE complex formation …

Role Models V. Knowledge: Should We Use Different Evolution Teaching Strategies For Students With Varying Levels Of Scientific Reasoning Skills?, Kenny Harrington, Jamie Jensen

Library/Life Sciences Undergraduate Poster Competition 2024

What We KNOW:

Learning the mechanisms of evolution (sometimes), i.e., Knowledge…

and having a Role Model present both serve to increase evolution acceptance.

Some have suggested that scientific reasoning ability predicts evolution acceptance, while others refute this.

We HYPOTHESIZE that students’ scientific reasoning ability moderates the effect of Knowledge on evolution acceptance. We PREDICT that those with higher reasoning skills will find Knowledge more compelling than Role Models.

Adapting The Auxin-Inducible Degron (Aid) System To The Zebrafish Model Organism, Dennis Li

Library/Life Sciences Undergraduate Poster Competition 2024

The Auxin Inducible Degron (AID) system is a conditional and reversible protein degradation system naturally occurring in plants. In the presence of the hormone Auxin, the AID tagged proteins are recruited into the plant’s E3 ubiquitin ligase machinery, ubiquitinated, and marked for degradation1. To adapt the AID system to the zebrafish model organism, our lab generated lines co-expressing Arabidopsis Thaliana plant TIR1 protein and GFP tagged with AID (GFP-AID) in superficially-located mechanosensory hair cells (HC) of the lateral line system and in spinal cord neurons found deeper in the body. Upon auxin application, GFP-AID expressed in the superficial HCs was …

Fishing For Neurocircuitry: Identifying Multi-Sensory Integrating Neurons In The Optic Tectum Of Zebrafish, Suehelen A. Garcia, Adeline Hamilton, Karianne Jex, Erika C. Marks, Jordan T. Yorgason, Tracianne B. Neilsen, Arminda Suli

Library/Life Sciences Undergraduate Poster Competition 2024

The superior colliculus (SC) is a mammalian midbrain structure involved in multimodal sensory integration and is implicated to have a role in neurodevelopmental disorders. Although the presence of multisensory integrating neurons (MINs) in the SC has been well documented by electrophysiology techniques, little is known about their morphological or molecular characterization. To identify and study MINs, we utilized SC’s non-mammalian homologous structure–the optic tectum (OT)–in the genetically tractable model organism zebrafish. In this process, we generated transgenic lines that allowed for fluorescent detection of neuronal activity by expressing the genetically engineered calcium indicators: cytoRGECO and H2B-jRGECO1a, respectively in mechanosensory hair …

Exploring Changes In Micro-Invertebrate Species Composition In Rock Pools Of The Colorado Plateau, Hamer Goolsby, Russell Rader, Sara Schenk

Library/Life Sciences Undergraduate Poster Competition 2024

• In ecology, desert rock pools form an ideal model ecosystem. These typically isolated pools a small enough that a researcher can observe the entire system and record everything going into and out of this aquatic system. This removes one of the most important confounding factors for observational studies in ecology, making rock pools an important system to understand.
• The rock pools of the Colorado Plateau in the western United States consist of three main types: 1) scoured pools in temporary stream channels that violently flood during rainstorms (locally called Tinajas), 2) shorthydroperiod pools which are shallow depressions (< 0.6 m deep) that thaw in March and dry by the end of April , and 3) long hydroperiod pools which are deep pools (1-3 m) that thaw in March and persist until June.
• Meiofauna (animals …

Tree Damage Patterning In Alaskan Forests, Emma Barton, Richard Gill, Haden Penrod

Library/Life Sciences Undergraduate Poster Competition 2024

• Tree defoliation (from insect parasites) is not abnormal in the densely forested areas of Alaska, but large outbreak events in recent years have led to cause for alarm.

• To better understand the factors affecting defoliation, we used remote sensing and GIS (geospatial information system) technologies to look at mortality spatial patterns across Hemlock and Spruce forests in southeast Alaska.

• Elevation and proximity to water as well as other factors were considered in determining the impacts of outbreak events due to evidence that changes in landscape can alter parasitism behaviors (Roland & Taylor, 1997).

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 …
