GSE280465 EPICv2 methylation data

GSE280465 EPICv2 methylation data

GSE280465 provides access to processed adult DNA methylation data derived from GEO accession GSE280465. The source data were generated on GPL33022, the Illumina Infinium MethylationEPIC version 2 array.

The ExperimentHub resource is a RangedSummarizedExperiment with beta, M, and CN assays for 163 adult samples from 47 individuals. Samples represent buccal, saliva, dried blood spot, and peripheral blood mononuclear cell tissues. Genomic ranges use hg38 coordinates.

The source publication is:

Apsley AT, Ye Q, Caspi A, Chiaro C, Etzel L, Hastings WJ, Heim CM, Kozlosky J, Noll JG, Schreier HMC, Shenk CE, Sugden K, Shalev I. Cross-tissue comparison of epigenetic aging clocks in humans. Aging Cell. 2025;24(4):e14451. doi:10.1111/acel.14451.

Accessing the resource

The data can be located in ExperimentHub using the GEO accession or the package name. The loaded object can then be inspected with standard SummarizedExperiment accessors.

library(ExperimentHub)
library(GSE280465)
library(SummarizedExperiment)

eh <- ExperimentHub()
query(eh, "GSE280465")

se <- GSE280465()
se

se <- GSE280465_GPL33022_EPICv2()
