Towards A New Role Of Mitochondrial Hydrogen Peroxide In Synaptic Function, Cliyahnelle Z. Alexander
Towards A New Role Of Mitochondrial Hydrogen Peroxide In Synaptic Function, Cliyahnelle Z. Alexander
Student Theses and Dissertations
Aerobic metabolism is known to generate damaging ROS, particularly hydrogen peroxide. Reactive oxygen species (ROS) are highly reactive molecules containing oxygen that have the potential to cause damage to cells and tissues in the body. ROS are highly reactive atoms or molecules that rapidly interact with other molecules within a cell. Intracellular accumulation can result in oxidative damage, dysfunction, and cell death. Due to the limitations of H2O2 (hydrogen peroxide) detectors, other impacts of ROS exposure may have been missed. HyPer7, a genetically encoded sensor, measures hydrogen peroxide emissions precisely and sensitively, even at sublethal levels, during …
Optogenetic Induction Of Mitochondrial Oxidative Stress As A Potential Model To Study Non-Hereditary Als, Samia Alam
Optogenetic Induction Of Mitochondrial Oxidative Stress As A Potential Model To Study Non-Hereditary Als, Samia Alam
Student Theses and Dissertations
Mitochondrial dysfunction is a common denominator of neurodegenerative diseases, including hereditary and non-hereditary Amyotrophic Lateral Sclerosis (ALS). Ten percent of ALS cases are hereditary while a majority are sporadic, with no known hereditary link. For effective therapeutic approaches to be developed, there is a need for development of a sporadic animal model to better understand disease mechanism. In previous work, our laboratory developed an animal model (known as mitokiller flies) to study sporadic cases of ALS. The work reported in this honors thesis focuses on the use of optogenetics and electrophysiology recording to study the formation of excessive hydrogen peroxide …
