A longitudinal DNA methylation dataset in primary human fibroblasts with mitochondrial genetic, metabolic, and endocrine perturbations

ABSTRACT: The current DNA methylation dataset (n=479) provides an epigenetic map of cultured primary human fibroblasts (in vitro) aged through the cellular lifespan. The dataset was generated using the Illumina EPIC bead array, which includes DNA methylation levels (0-1.0) at 866,091 CpG sites. This provides DNA methylation trajectories collected at high temporal frequency (every 8 days, ~7timepoints per a donor) across the entire replicative lifespan of primary human fibroblast cell lines from n=6 healthy male and female donors and n=3 donors with lifespan-altering mitochondrial disease caused by mutations in the SURF1 gene. The dataset can be integrated with other measures collected in parallel along the lifespan, including cytological (cell size, morphology), bioenergetic (energy expenditure, derived ATP synthesis rates from Seahorse), gene expression (RNA sequencing, GSE179848), secreted proteins, telomere length, and whole-genome sequencing (WGS) data. This dataset also includes experimental manipulations with treatments targeting oxidative phosphorylation (OXPHOS) and glycolysis, and glucocorticoid signaling, providing an opportunity to examine the influence of stress and bioenergetics on human aging biology.

A longitudinal RNA sequencing dataset in primary human fibroblasts with mitochondrial genetic, metabolic, and endocrine perturbations

Project description:The current RNA sequencing dataset (n=345) provides a transcriptional map of cultured primary human fibroblasts (in vitro) aged through the cellular lifespan. The dataset was generated from paired-end (150bp) Illumina HiSeq sequencing, with an average coverage of 38.3million reads per sample. These data contain gene expression trajectories collected at high temporal frequency (every 11 days, ~7timepoints per donor) across the replicative lifespan of primary human fibroblast cell lines from n=4 healthy male and female donors, and n=3 donors with lifespan-altering mitochondrial disease caused by mutations in the SURF1 gene. The dataset can be integrated with other measures collected in parallel along the lifespan, including cytological (cell size, morphology), bioenergetic (energy expenditure, derived ATP synthesis rates from Seahorse), epigenetic (DNA methylation, GSE179847), secreted proteins, telomere length, and whole-genome sequencing (WGS) data.

Lifelong Reduction in Complex IV Induces Tissue Specific Metabolic Effects But Does Not Reduce Lifespan or Healthspan in Mice

Project description:Loss of SURF1, a Complex IV assembly protein, was reported to increase lifespan in mice despite dramatically lower cytochrome oxidase (COX) activity. Consistent with this, our previous studies found advantageous changes in metabolism (reduced adiposity, increased insulin sensitivity and mitochon-drial biogenesis) in Surf1-/- mice. The lack of deleterious phenotypes in Surf1-/- mice is contrary to the hypothesis that mitochondrial dysfunction contributes to aging. We found only a modest (non-significant) extension of lifespan (7% median, 16% maximum) and no change in healthspan indices in Surf1-/- vs Surf1+/+ mice despite substantial decreases in COX activity (22-87% across tissues). Dietary restriction (DR) increased median lifespan in both Surf1+/+ and Surf1-/- mice (36 and 19%, respectively). We measured gene expression, metabolites and targeted expression of key metabolic proteins in adi-pose tissue, liver and brain in Surf1+/+ and Surf1-/- mice. Gene expression was differentially regulated in a tissue specific pattern. We found that many proteins and metabolites are downregulated in Surf1-/- adipose tissue and reversed by DR, while in brain most metabolites that changed were elevated in Surf1-/- mice. Finally, mitochondrial unfolded protein response (UPRmt)-associated proteins were not uniformly altered by age or genotype, suggesting the UPRmt is not a key player in aging or the response to reduced COX activity. While the changes in gene expression and metabolism may represent com-pensatory responses to mitochondrial stress, the important outcome of this study is that lifespan and healthspan are not compromised in Surf1-/- mice, suggesting that mitochondrial deficiencies may not be a critical determinant of lifespan.
