From: Concordant and discordant DNA methylation signatures of aging in human blood and brain
Overlap of genes associated with specific PCs. (A) Overlap of genes associated to probes with ≷ ± 2σ projection on PCs 1 to 3. (B) Overlap of genes associated to probes with ≷ ± 2σ projection on PC1 (blood–brain tissue related), PC4 (age in brain), and PC5 (age in brain and blood). (C) Overlap of the set of genes that contained probes with > 2σ projection with the set of genes with < − 2σ projection, for each PC of interest. PC, principal component.
