(Submitter supplied) Chronic pain is a global public health problem, but the underlying molecular mechanisms are not fully understood. Here we examine genome-wide DNA methylation, first in 50 identical twins discordant for heat pain sensitivity and then in 50 further unrelated individuals. Whole blood DNA methylation was characterized at 5.2 million loci by MeDIP-sequencing and assessed longitudinally to identify differentially methylated regions associated with high or low pain-sensitivity (pain-DMRs). more...

(Submitter supplied) Genome wide DNA methylation profiling with the HumanMethylation450 BeadChip (450k) of peripheral blood samples of 46 adult female monozygotic twin-pairs obtained at the same time point. Samples included 41 healthy females (not diagnosed with cancer to date) paired with their co-twin diagnosed with cancer within a 5 year window around the time of sampling as well as 5 extra pairs with a co-twin diagnosed with cancer within 11 to 5 years prior to blood sampling.

(Submitter supplied) Objective: Systemic lupus erythematosus (SLE) has limited monozygotic (MZ) twin concordance, implying a role for other pathogenic factors than genetic variation, such as epigenetic changes. Using the disease discordant twin model, we investigated genome-wide DNA methylation changes in sorted CD4+ T-cells, monocytes, granulocytes and B-cells in twin pairs with at least one SLE-affected twin. Methods: Peripheral blood from 15 SLE twin pairs (six MZ, nine dizygotic (DZ)) was processed using gradient density centrifugation for the granulocyte fraction. more...

(Submitter supplied) Human intelligence demonstrates one of the highest heritabilities among human quantitative traits. Phenotypically discordant monozygotic twins provide a way to identify loci reponsible for the phenotypical differences. We performed comprehensive DNA methylation analysis in monozygotic twins manifesting differences in IQ scores. Genes with significantly different methylation status are considered as candidates related to human intelligence.

(Submitter supplied) Human intelligence demonstrates one of the highest heritabilities among human quantitative traits. Phenotypically discordant monozygotic twins provide a way to identify loci responsible for normal-range intelligence. We conducted array-based genome-wide gene expression analysis aiming to identify genes displaying significant difference among monozygotic twin pairs manifesting between-co-twins IQ differences.

(Submitter supplied) Background and aims. The etiopathology of inflammatory bowel diseases is still poorly understood. To date, only few little data are available on the microbiota composition in ulcerative colitis (UC), representing a major subform of inflammatory bowel diseases. Currently, one of the main challenges is to unravel the interactions between genetics and environmental factors in the onset or during the progression and maintenance of the disease. more...

(Submitter supplied) To further our understanding of the role of DNA methylation in development, Methylated DNA Immunoprecipitation (MeDIP) was used in conjunction with a NimbleGen promoter plus CpG island array to identify Tissue and Developmental Stage specific Differentially Methylated DNA Regions (T-DMRs and DS-DMRs) on a genome-wide basis. Four tissues (brain, heart, liver, and testis) from C57BL/6J mice were analyzed at three developmental stages (15 day embryo, E15; new born, NB; 12 week adult, AD). more...

(Submitter supplied) Background: Imprinted genes are defined by their preferential expression from one of the two parental alleles. This unique mode of gene expression is dependent on allele-specific DNA methylation profiles established at regulatory sequences called imprinting control regions. These loci are frequently used as biosensors to study how environmental exposures affect methylation and transcription. However, a critical unanswered question is whether they are more, less or equally sensitive to environmental stressors as the rest of the genome. more...
