How The Molecular Vibrations Of Water May Prevent Skin Cancer, Jarlynn Ramirez, Angelina Georg, Colette Costello, Mahi Desai, Sandeep Dronavalli Apr 2024

How The Molecular Vibrations Of Water May Prevent Skin Cancer, Jarlynn Ramirez, Angelina Georg, Colette Costello, Mahi Desai, Sandeep Dronavalli

Undergraduate Student Symposium

Studies have shown that when DNA absorbs ultraviolet light it can become structurally damaged leading to a mutation and possibly skin cancer. However, exposing skin to sunlight rarely leads to a mutation. This indicates that after the ultraviolet light is absorbed by the DNA the energy from the light can either cause a structural change to the DNA (a mutation) or be dissipated in a way that does not damage the DNA. Absorption of ultraviolet light causes molecular vibrations in DNA and these vibrations are what likely leads to structural changes in the DNA. One way the structural changes could …

Measuring Drug Metabolism Efficiency Of P450 Enzyme, Rachel Gruboy, Kena Patel

Undergraduate Student Symposium

Cytochrome P450 enzyme is responsible for the majority of drug metabolism in the human body, generally increasing the drugs’ solubility for secretion. Drug companies have routinely tested how fast drugs are metabolized and the metabolites they produce, but the low efficiency of drug metabolism makes this measurement a challenging task. The purpose of this project was to increase metabolism efficiency by changing the reaction conditions. The drug metabolism of cytochrome P450 enzyme was measured using commonly prescribed medications. The P450 enzyme uses NADPH to reduce the heme iron- O2 complex making it highly reactive. This highly reactive center is …

Modeling Cysteinyl Leukotriene Receptor Antagonist Knw For Possible Optimized Asthma Treatment, Sreejani Jonnalagadda, Shalet James

Undergraduate Student Symposium

Under-diagnosed and under-treated, particularly in low- and middle-income countries, asthma has affected 262 million people globally in 2019. Cysteinyl leukotriene receptors (Cys-LTRs) are a δ-branch of class A G protein-coupled receptors associated with physiological functions in airways with allergic inflammation. Current antiasthmatic medications such as pranlukast inhibit CysLT1R, yet many patients still do not respond to this drug. To better understand this process, the related receptor CysLT2R has been identified as a promising drug target for not only asthma but also other conditions such as brain injury and cancer. CysLT1R is associated with bronchoconstriction, inflammation, and mucus production in the …

Interactions Between Atp Production, Growth Rate, And Antibiotic Lethality Determine The Inoculum Effect In Β-Lactamase-Expression Escherichia Coli, Ariane Kalifa, Philopatier Ibrahim, Kielan Singh Apr 2024

Interactions Between Atp Production, Growth Rate, And Antibiotic Lethality Determine The Inoculum Effect In Β-Lactamase-Expression Escherichia Coli, Ariane Kalifa, Philopatier Ibrahim, Kielan Singh

Undergraduate Student Symposium

Antibiotic resistance is a global threat, claiming approximately five million lives annually and impacting nations worldwide. In the U.S.A., this issue is significant, with 2.8 million diagnosed cases leading to 35,000 deaths each year. One way that bacteria can resist antibiotic treatment is through the inoculum effect (IE). IE explains how the concentration of antibiotics required to kill a population of bacteria increases as a function of bacterial density. Recently it was found that increasing ATP production/growth rate decreases the strength of IE. However, we do not know if this relationship can predict IE in bacteria that express β-lactamases as …

Navigating Murky Waters: State-Level Strategies For Wetland Preservation And Tile Drainage Regulation After Sackett V. Epa, Caleb M. Swanson

Honors Thesis

Wetlands are some of the world’s most valuable ecosystems, serving as provisioners of species habitat, carbon sequestration, flood mitigation, water quality purification, and other ecosystem services. Human development has resulted in substantial wetland loss the world over. In the 1970s, the United States Congress passed the Clean Water Act, giving the EPA broad authority over wetland protection. However, in the summer of 2023, the United States Supreme Court decided Sackett v. EPA, limiting the EPA’s jurisdiction over wetlands to those indistinguishably connected to generally recognized “Waters of the United States” and removing federal protection for millions of acres of wetlands, …

Dihydroceramide Desaturase Governs Endoplasmic Reticulum And Lipid Droplet Homeostasis To Promote Glial Function In The Nervous System, Yuqing Zhu Apr 2024

Dihydroceramide Desaturase Governs Endoplasmic Reticulum And Lipid Droplet Homeostasis To Promote Glial Function In The Nervous System, Yuqing Zhu

Arts & Sciences Graduate Student Theses and Dissertations

Dihydroceramide desaturase converts dihydroceramides to ceramides in the final step of de novo ceramide biosynthesis. Reduction of dihydroceramide desaturase DEGS1 function in humans leads to hypomyelinating leukodystrophy-18, but the etiology of this disease remains unclear. Using mutants from a forward genetic screen, we discovered that infertile crescent (ifc), the sole Drosophila dihydroceramide desaturase, governs central nervous system development and morphology. ifc is primarily expressed in glia and acts cell-autonomously in glia to control glial morphology and function during nervous system development. Loss of ifc leads to severe glial defects, particularly in cortex glia, including endoplasmic reticulum expansion, glial swelling, compromised …
