Epigenetic assimilation in the aging human brain

ABSTRACT: Epigenetic misregulation is consistent with the various non-Mendelian features of Alzheimer's disease (AD) and may even play an etiological role in the disease. We performed DNA modification profiling of post-mortem brain samples from twins who differed for age of AD onset and buccal samples from twins who were discordant for AD at the time of sample collection. We performed DNA methylome analysis on frontal cortex, cerebellum, or buccal tissues from monozygotic twins and dizygotic twins discordant for Alzheimerâs disease (AD) or disease age of onset. DNA samples were enriched for unmodified fraction of the genome using DNA-modification sensitive restriction enzyme digestion followed by adaptor-mediated PCR. The enriched fractions were labelled with a fluorescent dye (Cy3) and hybridized onto the array with a common reference pool (Cy5).

DNA modification study in major depressive disorder

Project description:Major depressive disorder (MDD) exhibits numerous clinical, epidemiological, and molecular features that are consistent with partially inherited and partially acquired epigenetic misregulation. We performed microarray based DNA modification study of MDD, utilizing affected and unaffected samples from white blood cells from monozygotic twins discordant for MDD, post-mortem prefrontal cortex tissues, and sperm samples. We performed DNA methylome analysis on white blood cells from monozygotic twins discordant for depression (n=200), pre-frontal cortex (n=71), and germline samples (n=33) from affected individuals and controls (total n=304). DNA samples were enriched for unmodified fraction of the genome using DNA-modification sensitive restriction enzyme digestion followed by adaptor-mediated PCR. The enriched fractions were labelled with a fluorescent dye (Cy5) and hybridized onto the array with a common reference pool (Cy3) generated from individuals unrelated to this study.

cirDNA methylome analysis in prostate cancer

Project description:DNA modification profiling of circulating DNA (cirDNA) from plasma samples from prostate cancer patients (T2-3N0Mx), benign prostatic hyperplasia and control individuals Epigenetic differences are a common feature of many diseases, including cancer, and disease-associated changes have even been detected in bodily fluids. DNA modification studies in circulating DNA (cirDNA) may lead to the development of specific non-invasive biomarkers. Three-conditions experiment: Prostate cancer (n=19), bening prostatic hyperplasia (n=20), controls without any know prostatic disease (n=20). cirDNA was isolated and the modified fraction of the genome was enriched using DNA-modification-sensitive digestion and adaptor-mediated PCR. Enriched fraction was labelled with Cy3. DNA samples extracted from white blood cells (WBC) of 20 individuals unrelated to this project were pooled and used as reference (Cy5-labelled).

Epigenome-wide Association Study of Obesity Susceptibility in Human Twins

Project description:The purpose of the current study was to use an epigenome-wide association approach (EWAS) to identify a potential DNA methylation alterations associated with obesity using twins discordant on obesity status. Buccal cells (from a cheek swab) were used as a purified marker cell for the epigenetic analysis. Analysis of differential DNA methylation regions (DMRs) was used to identify epigenetic associations with metabolic and dietary measures in obesity parameters discordant twins. An edgeR analysis provided a DMR signature with p<1e-04, but a false discovery rate analysis demonstrated a lack of significance due to low sample size and known multivariant origins of obesity.

Phenotypically concordant and discordant monozygotic twins display different DNA copy number variation profiles (BAC)

Project description:The exploration of copy number variation (CNV), notably of somatic cells, is an understudied aspect of genome biology. Any differences in the genetic make-up between twins derived from the same zygote represent an extreme example of somatic variation. We studied 19 pairs of monozygotic twins with either concordant or discordant phenotype using two platforms for genome-wide CNV analyses and show that CNVs exist within pairs in both groups. These findings impact our views of genotypic and phenotypic diversity in monozygotic twins, and suggest that CNV analysis in phenotypically discordant monozygotic twins may provide a powerful tool in identifying disease predisposition loci. Our results also imply that caution should be exercised with the interpretation of disease causality of de novo CNVs found in patients based on analysis of a single tissue in routine disease-related DNA diagnostics Keywords: copy number variation, concordant and discordant monozygotic twins

PLASMA PROTEOMIC ANALYSIS OF RARE BMI-DISCORDANT MONOZYGOTIC TWIN PAIRS

Project description:The aim of the current study is to establish the effect of excess body wiehgt and liver fat on plasma proteomic profile without interference from genetic variation. Label-free proteomics (HDMSE) was performed on plasma samples of young healthy monozygotic twins who were discordant for BMI. the twins were further subdivided into groups of liver fat discordant and liver fat concordant to see the efefct fo liver fat on plasma proteomic signature.

HumanMethylation450 (450k) data for 79 rheumatoid arthritis disease discordant monozygotic twin pairs

Project description:This project contains genome-wide DNA methylation data generated using the HumanMethylation450 BeadChip (Illumina), for 79 rheumatoid arthritis (RA) discordant monozygotic twin pairs. By investigating disease discordant monozygotic twins, DNA methylation can be assessed without the confounding influence of genetic heterogeneity which often affects case-control epigenome-wide association studies of common diseases. Twins were recruited from two cohorts; Arthritis Research UK in Manchester and TwinsUK in London.

Epigenetic Regulation of IL17RC in Age-related Macular Degeneration (MeDIP-chip)

Project description:Age-related macular degeneration (AMD) is the leading cause of irreversible blindness in the elderly population worldwide. Recent studies have demonstrated strong genetic associations between AMD and single nucleotide polymorphisms (SNPs) within genes such as CFH and HTRA1. However, we found monozygotic twins had discordant AMD phenotypes (one with disease, the other without disease), suggesting that an epigenetic mechanism may control the pathogenesis of AMD. We obtained genomic DNA from the twins' peripheral blood mononuclear cells (PBMCs) and subjected it to DNA methylation-chip analysis (MeDIP-chip) that profiled genome-wide DNA methylation patterns on promoters of all genes and microRNAs. Our MeDIP-chip analysis identified 256 genes with hypo-methylated promoters only in the twins with AMD and 744 genes with hyper-methylated promoters only in the twins with AMD. Importantly, the promoter region of IL17RC was associated with hypo-methylated CpG sites only in the twins with AMD but not in the twins without AMD. Two pairs of twins with discordant AMD phenotypes. MeDIP-chip analysis of DNA methylation patterns in PBMCs.
