(Submitter supplied) Mammals differ more than hundred fold in maximum lifespan, which can be altered in either direction during evolution, but the molecular basis for natural changes in longevity is not understood. Divergent evolution of mammals also led to extensive changes in gene expression within and between lineages. To understand the relationship between lifespan and variation in gene expression, we carried out RNA-seq-based gene expression analyses of liver, kidney and brain of 33 diverse species of mammals. more...

(Submitter supplied) 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. more...

(Submitter supplied) This dataset consists of liver and kidney gene expression profiles of young UM-HET3 mice subjected to the following compounds for 1 month: AS-703026 (liver and kidney), enzastaurin (liver and kidney), GDC-0941 (liver and kidney), ascorbyl-palmitate (kidney), AZD8055 (kidney) and KU0063794 (kidney). Corresponding age-, sex- and strain-matched littermate controls for kidney are also presented. This dataset complements liver RNAseq profiles of control UM-HET3 mice and mice subjected to ascorbyl-palmitate, AZD8055 and KU0063794 (collected and sequenced at the same time) stored at GSE131868.

(Submitter supplied) We used buccal samples from two different dog breeds with well established differences in average lifespan to perform genome-scale identification of ageing-associated differentially methylated positions (aDMPs) in a total of 48 different dogs. A significant proportion of aDMPs that gained methylation with age replicated in an independent cohort. Furthermore, we also show that human aDMPs show similar ageing-associated dynamics at the homologous genomic regions in the dog. more...

(Submitter supplied) Caloric restriction (CR) is the only non-genetic intervention to retard aging and increase longevity in a variety of species. It is important to understand the fundamental mechanism by which CR extends lifespan that remains elusive. Owing to well-established genomic tools and convenience of culture system, we used a single cell organism, Saccharomyces cerevisiae, to clarify the mechanisms of CR. In order to identify genes responsible for CR-mediated longevity, we performed microarray experiments across the longevity assurance time-points.

(Submitter supplied) Mammals differ more than 100-fold in maximum lifespan. Here, we conducted comparative transcriptomics on 26 species with diverse lifespans. We identified thousands of genes with expression levels negatively or positively correlated with a species' maximum lifespan (Neg- or Pos-MLS genes). Neg-MLS genes are primarily involved in energy metabolism and inflammation. Pos-MLS genes show enrichment in DNA repair, microtubule organization, and RNA transport. more...
