Bioenergetics As A Biomarker Of Health And Disease, Philip Kramer
Bioenergetics As A Biomarker Of Health And Disease, Philip Kramer

The increasing prevalence of metabolic syndrome, diabetes, atherosclerosis, and many other diseases only recently associated with aberrant metabolism, have led to a de-mand for clinical assays to determine a patient’s mitochondrial health. With the rapidly growing interest in personalized medicine, such an assay would ideally be able to capture the metabolic changes associated with oxidative stress, inflammation, and therapy of a patient in a swift and non-invasive manner. Short of tissue biopsies, this burgeoning field of Translational Bioenergetics has had minimal success in obtaining sufficient human cells and the means to assess them both accurately and swiftly. The purpose of …

The principal function of platelets is to regulate hemostasis, and dysfunction of platelet aggregation or activation can lead to either excessive thrombotic or hemorrhagic complications. It has been shown that the ability to generate ATP and exposure to oxidative stress can affect platelet thrombotic potential. While platelet metabolism has been extensively studied, the importance of substrate availability and metabolic plasticity in regulating aggregation under physiological or pathological conditions is not well understood. In this dissertation, we examined the reliance of platelets on different metabolic substrates, the importance of ATP production for aggregation in response to thrombin stimulation, metabolic stress following …

Neurodegenerative diseases, such as Parkinson's disease, Alzheimer's disease and Huntington's disease are all characterized by metabolic dysfunction, increased oxidative damage to proteins and organelles, formation of proteinaceous inclusions, decreased autophagic and proteasomal function, and eventual neuronal and glial cell death. While our understanding of the mechanisms that underlie many of these pathologies is constantly growing, their exact cause, onset, interplay and progression still remain unclear. The gap between the description of disease pathologies and understanding the fundamental mechanisms of disease pathogenesis, progression and potential therapeutics to mitigate disease progression is still large. Based on the observation that altered glucose utilization, …
