Project description:Genome-wide patterns of DNA methylation were quantified using the Illumina Infinium EPIC array (“EPIC array”) in DNA samples isolated from buccal swabs collected at ages 5, 10 and 18 and whole blood samples collected at age 18 from 118 Monozygotic twin pairs from the Environmental Risk (E-Risk) Longitudinal Twin Study. Comparison of DNA methylation profiles of 233 age 18 blood samples with data on EPIC and Illumina 450K methylation arrays.
Project description:Genome wide DNA methylation profiling of lung adenocarcinoma samples. Illumina Infinium 450K(n=61) and EPIC (n=27) arrays were used to obtain DNA methylation data.
Project description:In this epigenome-wide association study (EWAS), we examined the associations between PCDD, PCDF, and PCB exposures and DNA methylation. Whole blood DNA methylation was measured using Illumina EPIC arrays (n=292). We modeled lipid-adjusted toxic equivalencies (TEQs) for: ΣDioxins (sum of 28 PCDDs, PCDFs, cPCBs, and mPCBs), PCDDs, PCDFs, cPCBs, and mPCBs using robust multivariable linear regression adjusting for age, race, sex, smoking, total lipids, and estimated percentages of six blood cell types.
Project description:Genome wide DNA methylation profiling of serum samples from 20 individuals hospitalized with acute mania and 20 unaffected controls using the Illumina 450K methylation arrays.
Project description:In this study, we investigated whether stroke patients who later developed cancer exhibited an accelerated epigenetic age compared to those who did not. A total of 648 stroke patients were followed for 15 years, during which 83 individuals were diagnosed with cancer. Biological age (B-age) was estimated from DNA methylation data derived from whole blood samples collected within 24 hours of stroke onset. These samples were analyzed using the 450K or EPIC Illumina Beadchip arrays. We employed several epigenetic clocks to calculate B-age, including the Hannum, Horvath, PhenoAge, ZhangBLUP, ZhangEN, and the mitotic epiTOC clocks. After adjusting for multiple testing, competing risks, and key confounders, we found that patients who developed cancer were biologically older, as measured by the Hannum clock. This repository provides the raw idat files and processed DNA methylation values.
Project description:Determine methylation pattern in PDAC a genome-wide analysis was performed in a cohort of 167 PDAC and 29 adjacent pancreatic tissues samples using the Infinium 450k methylation arrays (Illumina).
Project description:The data contains Illumina 450k/EPIC array methylation files from 380 glioblastoma patients of the Heidelberg Neuro-Oncology Center
Project description:Genome wide DNA methylation profiling of paired parental and therapy resistant cancer cell lines. Parental cell lines are mostly established cell lines. Resistant cell lines were obtained through long term exposure of the parental cells to gradually increasing doses of cancer therapies. The Illumina Infinium 450k and EPIC Human DNA methylation Beadchips were used to obtain DNA methylation profiles across approximately 450,000 or 850,000 CpGs from the cells. Samples include 7 parental and 10 derived resistant cell lines.
Project description:The data contains Illumina 450k/EPIC array methylation files from 104 patients of the NOA-08 study comparing temozolomide alone vs. radiotherapy in elderly patients with glioblastoma
