Mechanisms Associated With Aging And Age-Related Disease In Drosophila, Melanie Jones
Mechanisms Associated With Aging And Age-Related Disease In Drosophila, Melanie Jones
Theses and Dissertations
Aging is an intrinsic process that is independent of obvious disease. In contrast to normal aging, age-related diseases are conditions that typically manifest at advanced ages, are associated with explicit pathology and cause disability and premature death. We used Drosophila as a model to investigate the molecular-genetic mechanisms associated with aging and age-related disease. Age-related locomotor impairment (ARLI) is a serious condition for the elderly and greatly impacts their quality of life. Toward identifying genes and mechanisms that influence ARLI, we performed a forward genetic screen using Drosophila mutants. This screen identified a loss of function mutant in PDK1, a …

Role Of Oxidative Reactive Species And Antioxidants In Metabolism And Transport Of Therapeutic Drugs, Svetlana Verenich
Theses and Dissertations
Oxidative stress (OS) is a frequent complication of various disease conditions such as Alzheimer’s and Parkinson’s disease, atherosclerosis, preeclampsia, rheumatoid arthritis, diabetes including gestational diabetes, etc. OS is defined as an imbalance between the production of reactive species and the ability of an organism to detoxify the reactive intermediates and repair the damage. As a result of OS, the excess of reactive species such as oxygen superoxide (O2-), hydroxyl radical (OH), peroxynitrite (ONOO−), 4-hydroxynonenal (4HNE), etc., have a tendency to react with nearby proteins/nucleic acids/lipids changing their functionality or inactivating them completely. The organism has many ways to protect itself …
