(Submitter supplied) Although the function of DNA methylation in gene promoter regions is well established in transcriptional repression, the function of the evolutionarily conserved widespread distribution of DNA methylation in gene body regions remains incompletely understood. Here, we show that DNA methylation is enriched in included alternatively spliced exons (ASEs) and inhibiting DNA methylation results in aberrant splicing of ASEs. more...

(Submitter supplied) The overall goal of this study was to clarify the role of MeCP2 in adult cognition. As one of the measures we analyzed gene expression changes associated with MeCP2 loss in the adult hippocampus. The analysis was performed in basal conditions and after exposure to a novel environment. We report gene expression data of mouse adult hippocampal tissue in which MeCP2 has been knockeddown in both conditions.

(Submitter supplied) We profiled CpG methylation for human T cells and compared this pattern with public T cell nucleosome (H2A.Z) and polymerase II profiles (SRA000234). Focusing on DNA regions surrounding the start codon and stop codon, instead of the transcription start and end sites, we discovered a very intriguing pattern, namely methylation and nucleosomal peaks at those regions, more prominent than peaks near transcript boundaries. more...

(Submitter supplied) Rett syndrome (RTT) is a severe neurodevelopmental disorder that is caused by mutations in the gene methyl-CpG-binding-protein-2 (MECP2). However, the molecular mechanism by which these mutations mediate the RTT neuropathology remains enigmatic. In this study, we stimulated MeCP2-null cortical neurons (in vitro) and brains (in vivo) of a RTT mouse model to explore the effect of the loss of MeCP2 function on the activity-dependent transcriptomes of the cortex and hippocampus, respectively, using RNA-seq. more...

(Submitter supplied) While intron retention (IR) is now recognized as a widespread and conserved mechanism of gene expression control, its regulation is poorly understood. Here, we identify significantly reduced DNA methylation levels near splice junctions flanking retained introns compared to non-retained introns in diverse primary cells and cell lines. Further, we identify increased IR following inhibition of DNA methylation indicating that reduced DNA methylation promotes IR. more...

(Submitter supplied) Rett syndrome is a severe neurodevelopmental disorder caused by loss-of-function mutations in the methyl-CpG-binding protein gene, MECP2. MeCP2 is a methyl-cytosine binding protein that is proposed to function as a transcriptional repressor. However, multiple gene expression studies comparing wild-type and MeCP2-deficient neurons have failed to identify gene expression changes consistent with loss of a classical transcriptional repressor. more...

(Submitter supplied) Growing evidence suggests that DNA methylation plays a role in tissue-specific differentiation. Current approaches to methylome analysis using MBD-enrichment are restricted to large (≥1 µg) DNA samples, limiting the analysis of small tissue samples. Here we present a technique which enables characterization of genome wide tissue-specific methylation patterns from nanogram quantities of DNA. We have developed a methodology utilizing MBD2b/MBD3L1-enrichment for methylated DNA, kinase pre-treated ligation-mediated PCR amplification (MeKL) and hybridization to the comprehensive high-throughput array for relative methylation (CHARM) customized NimbleGen 2.1M mouse tiling arrays (Feinberg_MM8_Me_HX1), which we termed MeKL-chip. more...

(Submitter supplied) MeCP2 plays a multifaceted role in gene expression regulation and chromatin organization. Interaction between MeCP2 and methylated DNA to regulate gene expression is well established. However, the widespread MeCP2 distribution suggests its additional interactions with chromatin. Here we show, by both biochemical and ChIP-seq analyses, that MeCP2 directly binds to nucleosome subunit proteins and is recruited to distinct chromatin regions where H3K27me3 is enriched. more...

(Submitter supplied) The global impact of DNA methylation on alternative splicing is largely unknown. Using a genome-wide approach in wild-type and methylation-deficient embryonic stem cells, we found that DNA methylation can act both as an enhancer and as a silencer of splicing, and affects the splicing of more than 20% of alternative exons. These exons are characterized by distinct genetic and epigenetic signatures. Alternative splicing regulation of a subset of these exons can be explained by Heterochromatin protein 1 (HP1), which silences or enhances exon recognition in a position-dependent manner. more...

(Submitter supplied) The parasitoid wasp Nasonia vitripennis is an emerging genetic model for functional analysis of DNA methylation. Here, we characterize genome-wide methylation at a base-pair resolution, and compare these results to gene expression across five developmental stages and to methylation patterns reported in other insects. An accurate assessment of DNA methylation across the genome is accomplished using bisulfite sequencing of adult females from a highly inbred line. more...

(Submitter supplied) The expression level in the parasitoid Nasonia vitripennis adult female samples was profiled and compared with the methylation pattern. Methylated and non-methylated genes showed markedly different patterns. The expression level was higher for methylated than non-methylated genes. non-nmethylated genes account for 99% of the genes that were not found to be expressed in the adult female RNA-seq data (FPKM < 0.1). more...

(Submitter supplied) MECP2 is critical for proper brain development and expressed at near-histone levels in neurons, but the mechanism of its genomic localization remains poorly understood. Using high-resolution MeCP2 binding data, we show that genetic features alone can predict binding with 88% accuracy. Integrating MeCP2 binding and DNA methylation in a probabilistic graphical model, we demonstrate that previously reported methylation preferences may be due to MeCP2’s affinity to GC-rich chromatin, a result replicated using published data. more...

(Submitter supplied) Disruption of the MECP2 gene leads to Rett syndrome (RTT), a severe neurological disorder with features of autism. MECP2 encodes a methyl-DNA-binding protein that is proposed to function as a transcriptional repressor, but, despite numerous studies examining neuronal gene expression in MeCP2 mutants, no coherent model has emerged for how MeCP2 regulates transcription. Here we identify a genome-wide length-dependent increase in the expression of long genes in neurons lacking MeCP2. more...
