    Here it is shown that telomere dysfunction drives metabolic and mitochondrial compromise. Mice with dysfunctional telomeres activate p53, which in turn represses PGC-1α and PGC-1β, master regulators of metabolic and mitochondrial processes. This results in reduced mitochondrial mass, mitochondrial dysfunction and reduced ATP generation, impaired gluconeogenesis, cariomyopathy and increased reactive oxygen species. This telomere–p53–PGC pathway shows how telomere dysfunction may compromise organ function and contribute to age-related disorders.

    After learning, memories are strengthened through a process called 'consolidation', which requires new gene and protein expression, rendering new information less vulnerable to disruption. Several transcription factor families are involved in this process, but many of the relevant downstream targets are unknown. Here, IGF-II, a protein typically implicated in somatic tissue growth and repair, is identified as an essential factor in memory retention. IGF-II initiates its own network of signalling cascades that can lead to synaptic potentiation and are most effective within a short time frame immediately after learning. Thus, IGF-II represents an endogenous target for potentially modulating cognitive enhancement.
