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.

Assessing the preservation of cytosine methylation in ancient DNA from five prehistoric Native American populations [PDF]

open access: yes, 2015
textCytosine methylation of CpG dinucleotides is an important epigenetic mark that regulates gene expression in humans. While methylation patterns in extant populations have been widely studied, few studies have attempted to analyze methylation in ...

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.

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.

Comprehensive methylome map of lineage commitment from haematopoietic progenitors. [PDF]

open access: yes, 2010
Epigenetic modifications must underlie lineage-specific differentiation as terminally differentiated cells express tissue-specific genes, but their DNA sequence is unchanged.

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 ...

DNA methylation and DNA methyltransferases [PDF]

open access: yes, 2017
The prevailing views as to the form, function, and regulation of genomic methylation patterns have their origin many years in the past, at a time when the structure of the mammalian genome was only dimly perceived, when the number of protein-encoding ...

Methylation status of Dnmt1 promoter depends on poly(ADP-ribosy)lation [PDF]

open access: yes, 2007
Research is focused on CpG islands and on the mechanism that poly(ADP-ribosyl)ation uses to defend the unmethylated state of these important DNA sequences which are located in the promoter regions of the housekeeping genes having a role of transcription ...
