The Shape Of Metabolism: Mitochondrial Dynamics, Remodeling, And Bioenergetic Reprogramming In Disease, Carl Decker

KGI Theses and Dissertations

Mitochondria are dynamic, double-membrane bound hubs of bioenergetics, cell signaling, and redox balance that exist as an oscillating network of fused superstructures and smaller, single organelles. Importantly, their position at the junction of catabolic and anabolic metabolism connects these morphological fluctuations to larger cellular metabolic programs, which in turn have implicated mitochondrial dynamics in a number of disease states and a varied set of cell phenomena. For example, differentiation of memory t-cells is dependent on mitochondrial network morphology, and in particular on remodeling dynamics that yield fused mitochondrial assemblies favoring oxidative phosphorylation-driven metabolism. In contrast, many cancers have been shown …
