Genome-wide profiling of DNA methylation reveals a class of normally methylated CpG island promoters. [PDF]

open access: yesPLoS Genetics, 2007
The role of CpG island methylation in normal development and cell differentiation is of keen interest, but remains poorly understood. We performed comprehensive DNA methylation profiling of promoter regions in normal peripheral blood by methylated CpG ...

GaussianCpG: a Gaussian model for detection of CpG island in human genome sequences

open access: yesBMC Genomics, 2017
Background As crucial markers in identifying biological elements and processes in mammalian genomes, CpG islands (CGI) play important roles in DNA methylation, gene regulation, epigenetic inheritance, gene mutation, chromosome inactivation and nuclesome ...

Preservation of methylated CpG dinucleotides in human CpG islands [PDF]

open access: yesBiology Direct, 2016
CpG dinucleotides are extensively underrepresented in mammalian genomes. It is widely accepted that genome-wide CpG depletion is predominantly caused by an elevated CpG > TpG mutation rate due to frequent cytosine methylation in the CpG context. Meanwhile the CpG content in genomic regions called CpG islands (CGIs) is noticeably higher.

An Epigenome-Wide DNA Methylation Map of Testis in Pigs for Study of Complex Traits

open access: yesFrontiers in Genetics, 2019
Epigenetic changes are important for understanding complex trait variation and inheritance in pigs that are also a valuable biomedical model for human health research.

Increased p16 DNA methylation in mouse thymic lymphoma induced by irradiation. [PDF]

open access: yesPLoS ONE, 2014
DNA methylation is an important part of epigenetics. In this study, we examined the methylation state of two CpG islands in the promoter of the p16 gene in radiation-induced thymic lymphoma samples.

DNA methylation changes in ovarian cancer are cumulative with disease progression and identify tumor stage

open access: yesBMC Medical Genomics, 2008
Background Hypermethylation of promoter CpG islands with associated loss of gene expression, and hypomethylation of CpG-rich repetitive elements that may destabilize the genome are common events in most, if not all, epithelial cancers.

Signal Processing Methods for Genomic Sequence Analysis [PDF]

open access: yes, 2007
Signal processing is the art of representing, transforming, analyzing, and manipulating signals. It deals with a wide range of signals, from speech and audio signals to images and video signals, and many others.

Base-pair resolution DNA methylation sequencing reveals profoundly divergent epigenetic landscapes in acute myeloid leukemia. [PDF]

open access: yesPLoS Genetics, 2012
We have developed an enhanced form of reduced representation bisulfite sequencing with extended genomic coverage, which resulted in greater capture of DNA methylation information of regions lying outside of traditional CpG islands.

Links between DNA methylation and nucleosome occupancy in the human genome

open access: yesEpigenetics & Chromatin, 2017
Background DNA methylation is an epigenetic modification that is enriched in heterochromatin but depleted at active promoters and enhancers. However, the debate on whether or not DNA methylation is a reliable indicator of high nucleosome occupancy has ...

Chicken microchromosomes are hyperacetylated, early replicating, and gene rich

open access: yes, 1998
The chicken karyotype consists of 39 chromosomes of which 33 are classed as microchromosomes (MICs). MICs contain about one third of genomic DNA. The majority of mapped chicken genes are assigned to macrochromosomes (MACs), but a recent study indicated ...
