Determining Antibiotic Efficacy On A Species Of Pseudomonas Bacteria Isolated From A Soil Sample, Austin Taylor, Peyton Wells, Alyssa Smith

Student Research Symposium

The Pseudomonas genus contains a variety of species of bacteria that play essential roles in soil health, plant growth, and microbial competition. Certain species exhibit biocontrol properties by producing antimicrobial compounds to protect plants from harmful pathogens. While our Pseudomonas species is normally non-pathogenic to plants and humans, it could transfer antimicrobial resistance genes to harmful pathogens in the environment. By studying the Minimum Inhibitory Concentration (MIC) of the isolated bacteria to several common antibiotics, we could identify antibiotic-sensitive strains that could be used in agriculture, or antimicrobial-producing strains that could serve as natural defenses for plants.

Solving The Structure Of An Ancestral Protein Tyrosine Phosphatase, Natalie Turcsanski, Edna Armah

Student Research Symposium

Protein tyrosine phosphatases (PTPs) regulate cell signaling by removing phosphate groups from tyrosine residues. Malfunction of these enzymes can lead to diseases such as diabetes and cancer. A conserved feature among PTPs is the catalytic acid loop, essential for phosphate removal. Computational analysis of PTP structures revealed that ancestral PTPs have considerable variation in conformations of this loop, sparking interest in their further study. The Asgard group, identified as ancestral to eukaryotic PTPs, was successfully expressed and purified under optimized conditions. Current efforts focus on optimizing crystallization to obtain larger crystals for structural analysis. This project will investigate the allosteric …


Determining The Function Of Type Iv-B Crispr-Cas Systems, Eric Jenkins, Brendon Guinn Apr 2025

Determining The Function Of Type Iv-B Crispr-Cas Systems, Eric Jenkins, Brendon Guinn

Student Research Symposium

CRISPR-Cas systems are a diverse group of prokaryotic adaptive immune systems that defend against Mobile Genetic Elements (MGEs) such as bacteriophages and plasmids. CRISPR-associated (Cas) proteins bind to guide RNAs (crRNAs) transcribed from a DNA repeat array (CRISPR array) containing spacers complementary to MGEs. Upon infection by a MGE, the Cas protein-crRNA complex binds to the target sequence in the invaders genome and cleaves the nucleic acid.

Activation Of Enkephalinergic Neurons Modulate Pain Within The Brain, Lucy N. Scribner, Oakley M. Statham, Greydon R. Durrant, Callie M. Newson

Student Research Symposium

The endogenous opioid system, consisting of three neuropeptides and canonical receptors, is ubiquitously expressed throughout the brain and is heavily involved in modulating pain[1]. However, research has placed tremendous focus on investigating the receptors of this system, and less attention has been devoted to the peptides. One such opioid peptide, enkephalin, is notably absent within the pain center of the brain, the periaqueductal gray (PAG)[2]. To further understand the role enkephalins play in modulating pain, we aimed to target and activate specific enkephalin-containing neurons that connect to the PAG. By activating these enkephalinergic projections, we hypothesized that this would lead …
