Description | Transcriptomics and methylomics of human monocytes [transcriptome]-GSE56045_family |
Purpose | To estimate residual sample contamination for monocyte data analysis, separate enrichment scores for neutrophils, B cells, T cells, and natural killer cells were calculated and provided as sample characteristics.The participant race, gender, and study site were provided as 'raceGenderSite variable' which represents a combination of those factors. |
Experimental Design | The current study is particularly focused on the relationships between transcriptomics and methylomics with age.Data includes transcriptomic and methylomic data from CD14+ samples, collected from 1,202 individuals ranging 44 - 83 years of age (Exam 1). Peripheral monocytes were isolated from blood (Exam 5) with anti-CD14 coated magnetic beads, and the Illumina HumanHT-12 v4 Expression BeadChip and the Illumina HumanMethylation450 BeadChip were used to provide genome-wide coverage of mRNA expression and DNA methylation, respectively. This data enabled us to identify CpG loci whose degree of methylation was associated with age (age-DMR),and identify age- and expression-associated methylation sites (age-eMS), whose degree of methylation was associated with age and cis-gene expression (+/- 1Mb), after adjusting for other covariates such as race, gender, study site, and sample contaimination with B-cells, T-cells, natural killer cells, and neutrophils. |
