Gene expression signatures of mammalian longevity across species. Gene expression signatures of mammalian longevity across species

Lifespan varies both within and across species, but the general principles of its control are not understood. To identify transcriptomic signatures of mammalian longevity, we sequenced multiple organs of young adult mammals corresponding to 8 different species, including Canadian beaver, long-tailed macaque, greater tube-nosed bat, baboon, white-footed mouse, sugar glider, Siberian chipmunk and American black bear. We aggregated this dataset with publicly available pan-mammalian data and performed multi-tissue gene expression analyses across 41 mammalian species. This allowed us to identifiy signatures of species longevity and assess their relationship with biomarkers of aging and lifespan-extending interventions. This dataset complements RNAseq profiles of tissues from 23 mammalian species stored at GSE43013. Overall design: RNA-seq gene expression profiling of 48 liver, kidney, brain and cerebellum samples from 8 mammalian species.
