We utilized Reduced Representation Bisulfite Sequencing to profile DNA methylomes from whole blood of mice to develop a robust predictor of mouse biological aging. Based on DNA methylation profiles of mice from various ages, strains, genetic backgrounds, and diets, an aging methylation signature was observed and an epigenetic clock was created with elastic net linear regression. Profiles from fibroblasts and iPSCs showed that the aging clock can be reset.

Deep data QC

metadata only · no data-level QC for this type

Standardized, field-standard QC computed by touching the data — every metric states how it was obtained

No quantitative QC rubric exists for this data type yet, so it is deliberately left unscored — this is an honest "not applicable", not a poor rating.

QC cost 22 s compute

measured = computed from the data · extrapolated/reported = derived or from the repository · dq-1.0 · provisional — verify independently
