The Effect Of Percussive Massage On Collagen Gene Expression In Skeletal Muscle, James Bartling, Robert D. Hyldahl, Emma Schaugaard, Mohadeseh Ahmadi

Library/Life Sciences Undergraduate Poster Competition 2024

INTRODUCTION

• Exercise is a critical aspect of healthy living due in part to its effects of muscle adaptation, which are largely regulated by alterations in gene expression

• Sedentary behavior can be required by diverse life circumstances, suggesting a need to reproduce the beneficial effects of exercise by an alternative means

• Like exercise, percussive massage introduces a mechanical strain on the muscle, which could potentially replicate a similar remodeling response of the extracellular matrix (ECM). However, this has not yet been studied

• Collagen 1,3,&4 are major components of the ECM that adapt in response to exercise, and …

The Changing Tumor Microenvironment Of Non-Small Cell Lung Cancer, Mackenzie Hansen, Kim O'Neill, Qin Zhou, Yoko Derose, Magdalena Kovacsovics, Benjamin Brintz, Benjamin L. Witt, Siwen Hu-Lieskovan

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 …

Targeting Hsp90: A Novel Approach To Combat Synovial Sarcomas, Peyton Worley, Jared Barrott, Matt Kirkham, Drake Heithoff

Library/Life Sciences Undergraduate Poster Competition 2024

Synovial sarcomas are rare muscle cancers that have very few targeted therapies. HSP90 is a protein upregulated in this form of cancer and many others. A screening of this cancer was done in vitro, using FDA-approved drugs, showing that HSP90 could be a promising treatment option. A novel HSP90 inhibitor was applied to human and mouse synovial sarcoma cell lines and was analyzed after receiving a drug treatment for HSP90.

Library/Life Sciences Undergraduate Poster Competition 2024

Introduction

• New genes are commonly found by randomly inducing mutations in model organisms.

• Mapping the mutations to the genome to find novel genes is difficult, time-consuming, and expensive.

• We created a bioinformatics program, MMAPPR, to automate this process.

• Here, we introduce a new algorithm, MMAPPR2, which requires little to no bioinformatics knowledge to use.

• MMAPPR2 makes several improvements that allow it to identify genes more rapidly and precisely.

• MMAPPR2 will aid the rapid identification of genes in a wide range of species and developmental systems.

Effects Of Post-Translational Histone Modifications On Transcription Rate, Jacob Hunter, Steven Johnson, Aaron Bohn, Sarah Ricks, Sarah Hodson, David Bates, Steven M. Johnson

Library/Life Sciences Undergraduate Poster Competition 2024

DNA structure and organization in eukaryotic cells significantly impacts the regulation of geneexpression, cellular properties and overall behavior. At the most fundamental unit of this organization,~147 bp of DNA wraps 1.7 times around a histone octamer core, forming a collective unit called thenucleosome. Positioning and occupancy of nucleosomes around promoter elements of genes is knownto be a strong regulator of transcription in eukaryotic nuclei. Post-translational modifications (PTM’s) tothe protruding N-terminal tails of histone proteins are known to influence chromatin structure and thusgene expression; however, relatively little is known about the residual effect of histone PTM’s ontranscription rate.

Effects Of Grass Species And Soil Types On Early Successional Forb Species, Raechel Hunsaker, April Hulet, Matthew Madsen, Mallory Hinton, Derek Tilley

Library/Life Sciences Undergraduate Poster Competition 2024

Many early successional plant species have been considered weeds because of their lack of forage value for livestock (Whitson and Burrill, 2009). However, these early successional plant species have the potential to aid rangeland restoration in a variety of ways including:

• Food source for pollinators (Dumroese et al., 2016).

• Soil partitioning for climax communities of native perennials (Tilley et al., 2022).

• Competition against invasive annual species (Leger et al., 2014). To determine which early colonizing (or pioneer) species have the greatest restoration potential, interspecific competitive interactions should be evaluated.

Diversity And Community Of Macroinvertebrates In Timpanogos Caves, Utah, Erika Frandsen, C. Riley Nelson

Library/Life Sciences Undergraduate Poster Competition 2024

The Timpanogos Cave System consists of three caves in American Fork, Utah. In 2003, the National Park Service (NPS) commissioned Dr. Riley Nelson and laboratory students to conduct a survey of the diversity and abundance of terrestrial arthropod species found within the caves. Over the two years they sampled in Timpanogos Caves, they identified 55 species of macroinvertebrates in an unpublished report. In the 20 years since the last sampling, many environmental factors could have changed in these caves, contributing to an overall decrease in both abundance and biodiversity of fauna. Therefore, we repeated the sampling done by the Nelson …

Library/Life Sciences Undergraduate Poster Competition 2024

One of the most important tests in the clinical laboratory is the Complete Blood Count, which involves identifying the white blood cells in a patient’s blood. The respective counts of the different white blood cell types correlate with various states of health and disease and are critical to diagnosing diseases such as leukemia. Leukemic cells (blasts) are considered especially difficult to distinguish, and it is of the upmost importance that these cells are identified correctly. To aid in the process of leukemic cell identification, we quantified fractal patterns in the chromatin of white blood cells and used the data to …

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 …

Cattle Resource Selection On Late Fall Sagebrush Steppe Habitat In Idaho, United States, Larry Cole Kempton, April Hulet, Jim Sprinkle, Randy Larsen, Jameson Brennan, Dan Lauritzen, Sawyer Fonnesbeck, Justin Hatch

Library/Life Sciences Undergraduate Poster Competition 2024

Introduction Targeted cattle grazing is increasingly recognized as an effective method for controlling invasive grasses like cheatgrass in sagebrush-steppe ecosystems1. However, there's a lack of understanding about cattle distribution and their preference for invasives during the dormant season. One statistical model that provides insights into cattle distribution and the selection of resources (e.g., vegetation) is the Resource Selection Function (RSF) model2. Our research objective is to utilize a resource selection function to predict the probability of cattle selecting a particular location, in our case areas with higher cheatgrass abundance, based on environmental variables. The development of a resource selection function …

 Big game guzzlers are open pools of water that are used to target species like mule deer and desert big horn sheep (Figure 2).  Most visitations to guzzlers are by native species not targeted by the guzzlers or wildlife management efforts (3).

Adhd Medication Is More Potent And Effective During Ovulation, Laurenf@Byu.Edu Ford

Library/Life Sciences Undergraduate Poster Competition 2024

• Women escalate psychostimulant abuse more quickly than men. Women who are prescribed psychostimulants for ADHD report fluctuations in drug efficacy that correspond to their menstrual cycle.

• In rodents, females acquire psychostimulant addiction more readily and release more dopamine (DA) in the dorsal striatum, an effect mediated by estrogen.

• However, the impact of the estrous cycle in the nucleus accumbens (NAc), a core region for learning and addiction in the ventral striatum, is underexplored.

• Here, we examine cocaine, methylphenidate (Ritalin), and methamphetamine (Desoxyn) effects on DA transmission in male and naturally-cycling female mice.

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 …

Farber Institute for Neuroscience Faculty Papers

Small-molecule modulators of diverse voltage-gated K⁺ (Kv) channels may help treat a wide range of neurological disorders. However, developing effective modulators requires understanding of their mechanism of action. We apply an orthogonal approach to elucidate the mechanism of action of an imidazolidinedione derivative (AUT5), a highly selective positive allosteric modulator of Kv3.1 and Kv3.2 channels. AUT5 modulation involves positive cooperativity and preferential stabilization of the open state. The cryo-EM structure of the Kv3.1/AUT5 complex at a resolution of 2.5 Å reveals four equivalent AUT5 binding sites at the extracellular inter-subunit interface between the voltage-sensing and pore domains of the …
