Genomic 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 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 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...
متن کاملAllele-Specific, Age-Dependent and BMI-Associated DNA Methylation of Human MCHR1
BACKGROUND Melanin-concentrating hormone receptor 1 (MCHR1) plays a significant role in regulation of energy balance, food intake, physical activity and body weight in humans and rodents. Several association studies for human obesity showed contrary results concerning the SNPs rs133072 (G/A) and rs133073 (T/C), which localize to the first exon of MCHR1. The variations constitute two main haplot...
متن کاملDNA Methylation Maintains Allele-specific KIR Gene Expression in Human Natural Killer Cells
Killer immunoglobulin-like receptors (KIR) bind self-major histocompatibility complex class I molecules, allowing natural killer (NK) cells to recognize aberrant cells that have down-regulated class I. NK cells express variable numbers and combinations of highly homologous clonally restricted KIR genes, but uniformly express KIR2DL4. We show that NK clones express both 2DL4 alleles and either o...
