Mediation Of The Uncoupled Enos Pathway Following Oxidative Stress Using Tetrahydrobiopterin And Nitric Oxide Donor Drugs To Restore Tetrahydrobiopterin Concentration, Brianna Munnich
Scholar Week 2016 - present
Presentation Location: Warming House, Olivet Nazarene University
Abstract
The eNOS pathway, found in the endothelium of blood vessels, is a key regulator of nitric oxide levels in the circulatory system. The pathway is controlled through several positive and negative feedback loops [2]. The cofactor tetrahydrobiopterin (BH4) is a major control point in this pathway and under conditions of stress can be reduced into the dihydrobiopterin (BH2) [2,6,7,8,9]. When the reduced form is predominant, the pathway produces reactive oxygen species (ROS) rather than nitric oxide, causing stress and damage to the vessels [6,7,8,9]. In this study, different treatments were studied …

The microbiome is a dynamic community that can positively and negatively influence host health. Lactobacillus reuteri is a probiotic that has received much attention for its ability to inhibit pathogens such as Salmonella Typhimurium, Escherichia coli, and Clostridium difficile. It does so by its unique ability to metabolize glycerol into the antimicrobial compound 3-HPA, which is commonly referred to as reuterin. The ability to secrete reuterin is dependent not only on glycerol availability but also the concentration of glucose. In fact, there appears to be a “goldilocks” ratio between glucose and glycerol as either too much or too …
