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 …

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, …

In humans, a P56S point mutation in the VAPB/ALS8 MSP domain is associated with amyotrophic lateral sclerosis (ALS) and late-onset spinal muscular atrophy (SMA). The N-terminal MSP domain is cleaved from the C-terminus, and secreted through an unknown, nonconventional manner. The P56S mutation inhibits secretion of the MSP domain. We use Caenorhabditis elegans to study live secretion of VPR-1, as well as to understand vMSP receptor signaling in muscle and gonad. To study the secretion mechanism of VPR-1 we created a transgenic line of C. elegans with a fluorescently tagged VPR-1. Using this model, we were able to visualize live …
