Project description:Whole-genome DNA methylation (baseline and following GR-stimulation with 1.5 mg dexamethasone p.o.) were analysed to identify glucocorticoid receptor (GR)-mediated changes in DNA methylation. Lifetime stress accelerates epigenetic aging. DNA methylation was assessed in whole blood at baseline and 3 hours after stimulation with the selective GR agonist dexamethasone (1.5 mg p.o.). Blood was collected in EDTA vacuum tubes prior to extraction. DNA methylation was interrogated for each sample using the HumanMethylation450 BeadChip (Illumina). Supplementary files 'GSE74414_unmethylated_signals_353_CpG.txt', 'GSE74414_methylated_signals_353_CpG.txt', and 'GSE74414_detection.p.values_353_CpG.txt' include the raw data for the 353 CpGs used in the analysis in the associated manuscript. Supplementary file 'GSE74414_beta_values_353_CpG.txt' includes the processed data for the 353 CpGs used in the analysis in the associated manuscript. The raw and processed data for the remaining features included in Platform GPL13534 are embargoed.
Project description:Genome wide DNA methylation profiling of non-pathologic peripheral blood from subjects with no history of cancer. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in peripheral blood. Samples included 205 normal control peripheral blood samples.

The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in peripheral blood. Samples included 205 normal control peripheral blood samples. Bisulphite converted DNA from the 205 samples were hybridized to the Illumina Infinium 27k Human Methylation Beadchip v1.2
Project description:Genome wide DNA methylation profiles of cerebellum from HIV positive and HIV negative human subjects. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 486,000 CpGs. Dataset included 92 subjects from the USA. The epigenetic clock software (Horvath 2013) was used to measure epigenetic age acceleration effects and to relate them to HIV status.

The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 486,000 CpGs. Dataset included 20 subjects from the USA. The epigenetic clock software (Horvath 2013) was used to measure epigenetic age acceleration effects and to relate them to HIV status.
Project description:Genome wide DNA methylation profiling and semi-supervised classification of blood samples from a case-control study of head and neck squamous cell carcinoma (HNSCC). The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in peripheral blood. Samples included peripheral blood samples from 92 incident cases of HNSCC and 92 control subjects.

The epigenetic clock software (Horvath 2013) was used to measure epigenetic age acceleration effects and to relate them to HIV status. Bisulphite converted DNA from the 20 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip. 8 HIV+ subjects were compared to 12 HIV- subjects.
Project description:Genome wide DNA methylation profiles of Frontal Lobe from HIV positive and HIV negative human subjects. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 486,000 CpGs. Dataset included 33 subjects from the USA. The epigenetic clock software (Horvath 2013) was used to measure epigenetic age acceleration effects and to relate them to HIV status. Bisulphite converted DNA from the 33 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip. 8 HIV+ subjects were compared to 25 HIV- subjects.
