DNA methylation status predicts cell type-specific enhancer activity.
Cell-selective glucocorticoid receptor (GR) binding to distal regulatory elements is associated with cell type-specific regions of locally accessible chromatin. These regions can either pre-exist in chromatin (pre-programmed) or be induced by the receptor (de novo). Mechanisms that create and maintain these sites are not well understood. We observe a global enrichment of CpG density for pre-pro...
متن کاملAllele-specific DNA methylation: beyond imprinting.
Allele-specific DNA methylation (ASM) and allele-specific gene expression (ASE) have long been studied in genomic imprinting and X chromosome inactivation. But these types of allelic asymmetries, along with allele-specific transcription factor binding (ASTF), have turned out to be far more pervasive-affecting many non-imprinted autosomal genes in normal human tissues. ASM, ASE and ASTF have now...
متن کاملLineage-specific DNA methylation in T cells correlates with histone methylation and enhancer activity.
DNA methylation participates in establishing and maintaining chromatin structures and regulates gene transcription during mammalian development and cellular differentiation. With few exceptions, research thus far has focused on gene promoters, and little is known about the extent, functional relevance, and regulation of cell type-specific DNA methylation at promoter-distal sites. Here, we prese...
متن کاملGenomic landscape of human allele-specific DNA methylation.
DNA methylation mediates imprinted gene expression by passing an epigenomic state across generations and differentially marking specific regulatory regions on maternal and paternal alleles. Imprinting has been tied to the evolution of the placenta in mammals and defects of imprinting have been associated with human diseases. Although recent advances in genome sequencing have revolutionized the ...
متن کاملRapid and quantitative method of allele-specific DNA methylation analysis.
Several biological phenomena depend on differential methylation of chromosomal strands. While understanding the role of these processes requires information on allele-specific methylation, the available methodologies are not quantitative or labor-intensive. We describe a novel, rapid method to quantitate allele-specific DNA methylation based on the combination of bisulfite PCR and Pyrosequencin...
