A coherent approach for analysis of the Illumina HumanMethylation450 BeadChip improves data quality and performance in epigenome-wide association studies

ABSTRACT: We developed a comprehensive analysis pipeline to conduct Epigenome-wide Association Studies (EWAS) using the Illumina Infinium HumanMethylation450 BeadChip, based on data from 2,664 individuals, and 36 samples measured in duplicate. We propose new approaches to quality control, data normalisation and batch correction through control-probe adjustment, and demonstrate that these improve data-quality. Using permutation testing we establish a null hypothesis for EWAS, show how it can be affected by correlation between individual methylation markers and present methods to restore statistical independence. Bisulfite-converted DNA for 2,664 human samples and 36 technical replicates were hybridised to the Illumina Infinium 450k Human Methylation Beadchip v1.2.

Novel DNA methylation targets in oral rinse samples predict survival of patients with oral squamous cell carcinoma

Project description:Epigenome-wide association study (EWAS) of oral rinse samples from a cohort of 82 oral squamous cell carcinoma (OSCC) patients. The Illumina Infinium HumanMethylation450 Beadchip was used to obtain DNA methylation profiles across approximately 450,000 CpGs in oral rinse samples. Bisulphite lsconverted DNA from the 82 oral rinse samples were hybridized to the Illumina Infinium HumanMethylation450 Beadchip

Illumina Infinium HumanMethylation450 Genome-wide Methylation Levels at Baseline and 6 months after undergoing Aerobic and Stretch Exercise Activities

Project description:Elderly AA volunteers confirmed MCI assigned into a six-month program of aerobic exercise (eleven participants) underwent a 40-minute supervised-training 3-times/week and controls (eight participants) performed stretch training. Participants had maximal oxygen consumption (VO2max) test and Genome-wide methylation levels at CpG sites using the Infinium HumanMethylation450 BeadChip assay at baseline and after a six-month exercise program.

Leukocyte-adjusted epigenome-wide association studies of blood from solid tumor patients

Project description:Epigenome-wide association study (EWAS) of blood samples from a case-control study of bladder 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 peripheral blood samples from 223 incident cases of bladder cancer and 205 control subjects. Bisulphite converted DNA from the 428 samples were hybridized to the Illumina Infinium 27k Human Methylation Beadchip v1.2

Infinium HumanMethylation450 BeadChip Array analysis of human breast cancer cell line MDA-MB-231

Project description:Breast cancer metastasis may occur rapidly after tumor development and is responsible for the high mortality rate of this disease. ITIH5 has been shown being lost in tumor progression of various cancer types including breast cancer. Its dysfunction was associated with poor prognosis, while mechanisms of ITIH5 biology are still unrevealed. ITIH5 promoter methylation and expression was analyzed using an Infinium HumanMethylation450 BeadChip Array and Affymetrix 1.0 ST gene array, respectively, to identify ITIH5-associated gene signatures and signaling pathways. MDA-MB-231 cells were transfected with ITIH5-pBK-CMV expression vector, containing the full-length human ITIH5 cDNA derived from normal breast tissue, or the empty vector. Single-cell clones were selected by limited dilution under geneticine (G418) pressure. We compared the transcriptomic and epigenomic profile of wildtype MDA-MB-231 cells, mock clones without ITIH5 expression (clone 1 and 2) and ÎpBK-ITIH5 clones (clone 4, 7 and 12). Related transcription profiling data are found under accession <a href=\../E-MTAB-1813/\>E-MTAB-1813</a>.
