Project description:Copy number variations (CNVs) constitute the largest portion of the human genome variation. We determined a genome-wide high resolution SNP/CNV haplotype structure of Asians, by analyzing a collection of complete hydatidiform moles (CHMs) of Japanese, using high-density DNA arrays. CHMs are tissues carrying duplicated haploid genomes derived from single sperms, and are suitable material for the detection of CNVs, because they are expected to reveal greater signal to noise ratio in hybridization experiments. Also, the absence of heterozygosity ensures straightforward CNV interpretation without being bothered by overlapping CNV segments. We genotyped 100 CHM genomes using Affymetrix SNP 6.0 and Illumina 1M-duo, created a definitive haplotype map including 1.7 million SNPs and 2339 CNV region (CNVR) that is presented as D-HaploDB Phase 4.1.
Project description:Genome wide DNA methylation profiling of A2780 cells 1) infected with control virus, no H2O2 (Scr_mock), 2) infected with control virus with H2O2 treatment (30 min plus 2.5 h resting) (Scr_H2O2), 3) infected with shTET2 virus, no H2O2 (shTET2_mock), and 4) infected with shTET2 virus, with H2O2 treatment (30 min plus 2.5 h resting) (shTET2_H2O2, two biological replicates). The Illumina’s Infinium Human Methylation450 Beadchip Kit (WG-314-1001) was used to obtain DNA methylation profiles across approximately 450,000 CpGs.

Illumina Human1M-Duov3 BeadChip analyses were performed according to the manufacturer's directions on DNA extracted from 97 complete hydatidiform moles (CHMs) tissues collected throughout Japan.
Project description:Genome wide DNA methylation profiling of A2780 cells untreated (mock), treated with H2O2 for 30 min (H2O2 30 min), or treated with H2O2 for 30 min with additional 2.5 hour resting ( H2O2 3h) . The Illumina’s Infinium Human Methylation450 Beadchip Kit (WG-314-1001) was used to obtain DNA methylation profiles across approximately 450,000 CpGs.
Project description:A core task to understand the consequences of non-coding single nucleotide polymorphisms (SNP) is to identify their genotype specific binding of transcription factor (TF). Here, we generate a large-scale TF-SNP interaction map for a selection of 116 colorectal cancer (CRC) risk loci and validated TF binding to 10 putatively functional SNPs. Our data further revealed TF binding complexity adjacent to the 116 risk loci, adding an additional layer of understanding to regulatory networks associated with CRC relevant loci.
