In recent years, hydrogen sulfide (H2S) has been identified as a ubiquitous cell signaling molecule. In addition to its diverse physiological roles, H2S has emerged as a possible drug therapy, with a wide range of applications. Along with cytoprotective effects in pathological states such as ischemia-reperfusion injury, H2S has been shown to decrease aerobic metabolism in a reversible manner. This dissertation is focused on exploring H2S-induced hypometabolism and the implications therein for human health and disease. We have shown that rats exposed to 80 ppm H2S gas in combination with low oxygen (10.5% O2) for 6 hr exhibit decreases in …

Neurodegenerative disease encompasses a wide range of conditions and pathologies that can manifest at any age depending on the etiology. A major factor in both early onset and age-related neurodegeneration is mitochondrial dysfunction. To investigate how mitochondrial bioenergetics is affected by cellular stress, we used an in vitro culture system to examine mitochondrial function in response to oxidative stress. We also studied an in vivo model of neuronal ceroid lipofuscinosis to determine the impact of deficient autophagy-lysosomal activity on mitochondrial morphology, composition and function. In vitro we found that retinoic acid-induced differentiation of dopaminergic neuroblastoma SH-SY5Y cells exhibited increased mitochondrial …
