Deletion of the Mitochondrial Chaperone TRAP-1 Uncovers Global Reprogramming of Metabolic Networks

Deletion of mitochondrial protein may extend lifespan, reduce age-related disease [mouse]

Deletion of the mitochondrial chaperone TRAP-1, a regulator of bioenergetics in tumors, reduces the incidence of age-associated pathologies, including obesity, inflammatory tissue degeneration, dysplasia, and spontaneous tumor formation. This is accompanied by global upregulation of oxidative phosphorylation and glycolysis transcriptomes, causing deregulated mitochondrial respiration, oxidative stress, impaired cell proliferation, and a switch to glycolytic metabolism in vivo.
