Aging Mouse Brain Mitochondria LC-MS/MS

ABSTRACT: This study investigates the proteomic alterations in brain mitochondria isolated from 5- (mature), 12- (old), and 24-month-old (aged) mice to examine normal "healthy" aging. Using quantitative mass-spectrometry based super-SILAC, our findings revealed global proteomic changes in brain mitochondria identifying several metabolic pathways including glycolysis, the tricarboxylic acid cycle, and oxidative phosphorylation. Overall, we found that the bioenergetic function of these mitochondria was preserved suggesting the proteomic alterations potentially allow for compensatory mechanisms to combat aging.
