Methylenetetrahydrofolate Reductase CpG Islands: Epigenotyping [PDF]

open access: yesJournal of Clinical Laboratory Analysis, 2015
BackgroundDetermination of the differential DNA methylation patterns of methylenetetrahydrofolate reductase (MTHFR) that are associated with differential MTHFR activity is important to understand the pathogenesis of ischemic stroke. However, to date, no data are available on the differential DNA methylation profiles of Kelantanese Malays. Therefore, we

DNMT inhibitors reverse a specific signature of aberrant promoter DNA methylation and associated gene silencing in AML [PDF]

open access: yes, 2014
<b>Background</b>. Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) are neoplastic disorders of hematopoietic stem cells. DNA methyltransferase inhibitors (DNMTi), 5-azacytidine (AzaC) and 5-aza-2’-deoxycytidine (Decitabine),

Nucleosome repositioning links DNA (de)methylation and differential CTCF binding during stem cell development [PDF]

open access: yes, 2014
During differentiation of embryonic stem cells, chromatin reorganizes to establish cell type-specific expression programs. Here, we have dissected the linkages between DNA methylation (5mC), hydroxymethylation (5hmC), nucleosome repositioning, and ...

Factors to preserve CpG-rich sequences in methylated CpG islands [PDF]

open access: yesBMC Genomics, 2015
Mammalian CpG islands (CGIs) normally escape DNA methylation in all adult tissues and developmental stages. However, in our previous study we unexpectedly identified many methylated CGIs in human peripheral blood leukocytes. Methylated CpG dinucleotides convert to TpG dinucleotides through deaminization of their cytosine bases more frequently than ...

Features of mammalian microRNA promoters emerge from polymerase II chromatin immunoprecipitation data [PDF]

open access: yes, 2009
Background: MicroRNAs (miRNAs) are short, non-coding RNA regulators of protein coding genes. miRNAs play a very important role in diverse biological processes and various diseases.

Epigenetics as a mechanism driving polygenic clinical drug resistance [PDF]

open access: yes, 2006
Aberrant methylation of CpG islands located at or near gene promoters is associated with inactivation of gene expression during tumour development.

Eicosapentaenoic acid induces DNA demethylation in carcinoma cells through a TET1-dependent mechanism [PDF]

open access: yes, 2018
In cancer cells, global genomic hypomethylation is found together with localized hypermethylation of CpG islands within the promoters and regulatory regions of silenced tumor suppressor genes.

Modeling DNA methylation dynamics with approaches from phylogenetics [PDF]

open access: yes, 2014
Methylation of CpG dinucleotides is a prevalent epigenetic modification that is required for proper development in vertebrates, and changes in CpG methylation are essential to cellular differentiation.

Intragenic CpG Islands and Their Impact on Gene Regulation [PDF]

open access: yesFrontiers in Cell and Developmental Biology, 2022
The mammalian genome is depleted in CG dinucleotides, except at protected regions where they cluster as CpG islands (CGIs). CGIs are gene regulatory hubs and serve as transcription initiation sites and are as expected, associated with gene promoters. Advances in genomic annotations demonstrate that a quarter of CGIs are found within genes.
