An AP endonuclease functions in active DNA demethylation and gene imprinting in Arabidopsis [corrected]. [PDF]
Active DNA demethylation in plants occurs through base excision repair, beginning with removal of methylated cytosine by the ROS1/DME subfamily of 5-methylcytosine DNA glycosylases.

DNA Methylation and Demethylation in Arabidopsis [PDF]
Writing about a biological subject based on one species can limit the scope of the discussion, but in the case of DNA methylation and Arabidopsis, the restriction is entirely appropriate. Unlike many other popular model organisms, Arabidopsis has retained and embellished a multi-layered methylation system that contributes to gene and transposon ...

DNA Methylation and Demethylation in Mammals [PDF]
Cell type-specific DNA methylation patterns are established during mammalian development and maintained in adult somatic cells. Understanding how these patterns of 5-methylcytosine are established and maintained requires the elucidation of mechanisms for both DNA methylation and demethylation.

: RUNX1 is an essential master transcription factor in hematopoietic development and plays important roles in immune functions. Although the gene regulatory mechanism of RUNX1 has been characterized extensively, the epigenetic role of RUNX1 remains ...

Active DNA demethylation is required for sexual reproduction in plants, but the underlying mechanisms are unknown. Here, the authors show that the DNA glycosylases DEMETER and REPRESSOR OF SILENCING 1 enable the DNA demethylation-dependent activation of ...

GADD45A does not promote DNA demethylation.
Although DNA methylation patterns in somatic cells are thought to be relatively stable, they undergo dramatic changes during embryonic development, gametogenesis, and during malignant transformation.

Gemcitabine functions epigenetically by inhibiting repair mediated DNA demethylation.
Gemcitabine is a cytotoxic cytidine analog, which is widely used in anti-cancer therapy. One mechanism by which gemcitabine acts is by inhibiting nucleotide excision repair (NER).

Methylation-sensitive expression of a DNA demethylase gene serves as an epigenetic rheostat. [PDF]
Genomes must balance active suppression of transposable elements (TEs) with the need to maintain gene expression. In Arabidopsis, euchromatic TEs are targeted by RNA-directed DNA methylation (RdDM).

Background DNA methylation is a fundamental epigenetic modification that is involved in many biological systems such as differentiation and disease. We and others recently showed that some transcription factors (TFs) are involved in the site-specific ...
