Infinium MethylationEPIC Arrayは、バイサルファイト処理とIllumina®技術に基づくゲノムワイドのDNAメチル化解析技術です。これは、一塩基分解能を有するゲノム全体にわたる850,000を超えるヒトCpG位置のメチル化レベルの定量的な検出を可能にします。

バイサルファイトで処理すると、メチル化されたシトシン塩基は変化しませんが、メチル化されていないシトシン塩基はウラシルに変換されます。Infinium HD配列技術は、メチル化部位と非メチル化部位に対して各々に設計された部位特異的プローブを用いて、これらの分化した遺伝子座を調べます。調べられた遺伝子座のメチル化のレベルは、メチル化部位と非メチル化部位との蛍光シグナルの比を計算することによって決定されます。

    Differential methylation analysis

    Identification of differentially methylated CpGs between sample groups.

    Files provided:

    • Report with summary of differential methylation analysis and plots
    • File containing the differentially methylated CpGs and breakdown of those positions in regional analysis (CpG islands, shelves, shores and open sea)
    • File containing differential methylated regions (DMRs)

    Gene ontology terms analysis

    Enrichment analysis on gene sets. Gene Ontology terms that are overrepresented in differentially bound regions may indicate the underlying biological processes involved.

    Enhanced cell deconvolution of peripheral blood using DNA methylation for high-resolution immune profiling
    Lucas A Salas, Ze Zhang, Devin C Koestler, Rondi A Butler, Helen M Hansen, Annette M Molinaro, John K Wiencke, Karl T Kelsey, Brock C Christensen
    DNA methylation microarrays can be employed to interrogate cell-type composition in complex tissues. Here, we expand reference-based deconvolution of blood DNA methylation to include 12 leukocyte subtypes (neutrophils, eosinophils, basophils, monocytes, B cells, CD4+ and CD8+ naïve and memory cells, natural kil...

    Interplay between Histone and DNA Methylation Seen through Comparative Methylomes in Rare Mendelian Disorders
    Guillaume Velasco, Damien Ulveling,Sophie Rondeau,Pauline Marzin,Motoko Unoki,Valérie Cormier-Daire, Claire Francastel
    DNA methylation (DNAme) profiling is used to establish specific biomarkers to improve the diagnosis of patients with inherited neurodevelopmental disorders and to guide mutation screening. In the specific case of mendelian disorders of the epigenetic machinery, it also provides the basis to infer mechanistic aspects...

    Genome-wide DNA methylation and transcriptome integration reveal distinct sex differences in skeletal muscle
    Shanie Landen, Macsue Jacques , Danielle Hiam , Javier Alvarez, Nicholas R Harvey, Larisa M. Haupt, Lyn R, Griffiths, Kevin J Ashton, Séverine Lamon, Sarah Voisin, Nir Eynon
    Nearly all human complex traits and diseases exhibit some degree of sex differences, and epigenetics contributes to these differences as DNA methylation shows sex differences in various tissues. However, skeletal muscle epigenetic sex differences remain largely unexplored, yet skeletal muscle displays distinct sex d...

    ZNF718, HOXA4, and ZFP57 are differentially methylated inperiodontitis in comparison with periodontal health: Epigenome-wide DNAmethylation pilot study.
    Hernández H.G. et al.
    OBJECTIVE: To investigate the differences in the epigenomic patterns of DNA methylation in peripheral leukocytes between patients with periodontitis and gingivally healthy controls evaluating its functional meaning by functional enrichment analysis. BACKGROUND: The DNA methylation profiling of peripheral leukocytes ...
