DNA methylation profiling for HEK-293T cells transfected with GFP and DMEΔ

ABSTRACT: Methylome data obtained from human embryonic kindey (HEK)-293T cells expressing a GFP (293T-GFP) or a truncated form of Arabidopsis DEMETER (DME) 5-methylcytosine (5mC) DNA glycosylase (293T-DMEΔ) analyzed on a Human Methylation 450K BeadChip platform (Illumina). These methylation array data revealed genome-wide DNA methylation patterns of the 293T-GFP cells (without direct 5mC excision activity) and 293T-DMEΔ cells (with artificially implemented direct 5mC excision activity).

The Catalytic Core of DEMETER Guides Active DNA Demethylation in Arabidopsis

Project description:The Arabidopsis DEMETER (DME) DNA glycosylase demethylates the maternal genome in the central cell prior to fertilization, and is essential for seed viability. DME preferentially targets small transposons that flank coding genes, influencing their expression and initiating plant gene imprinting. DME also targets intergenic and heterochromatic regions, and how it is recruited to these differing chromatin landscapes is unknown. The C-terminal DME catalytic core consists of three conserved regions required for catalysis in vitro. We show that the catalytic core of DME guides active demethylation at endogenous targets, rescuing the developmental and genomic hypermethylation phenotypes of DME mutants. However, without the N-terminus, heterochromatin demethylation is significantly impeded, and abundant CG-methylated genic sequences are ectopically demethylated. We used comparative analysis to reveal that the conserved DME N-terminal domains are only present in the flowering plants, whereas the domain architecture of DME-like proteins in non-vascular plants mainly resembles the catalytic core, suggesting that it might represent the ancestral form of the 5mC DNA glycosylase found in all plant lineages. We propose a bipartite model for DME protein action and suggest that the DME N-terminus was acquired late during land plant evolution to improve specificity and facilitate demethylation at heterochromatin targets.

Genome-wide bisulphite sequencing of Arabidopsis thaliana embryo and endosperm

Project description:The DEMETER (DME) DNA glycosylase mediates genome-wide DNA demethylation and is required for endosperm genomic imprinting and embryo viability. Targets of DME-demethylation are small, AT-rich transposons and boundaries of large heterochromatic transposons, but how DME interacts with chromatin is unclear. To investigate the interaction between DME and chromatin, we analyzed DNA methylation in Arabidopsis seeds and pollen deficient in the chromatin remodeler FAcilitates Chromatin Transactions (FACT) complex. We find that FACT co-localizes with nuclear DME, and is required for DME activity in chromatin domains with high nucleosome occupancy and histone modifications associated with heterochromatin, which comprise over half of DME target loci. We also demonstrate that heterochromatin-associated linker histone H1 mediates the requirement for FACT at a subset of DME-target loci. However, FACT is not required for DME demethylation of targets in euchromatic regions. Thus, chromatin structure determines the degree to which FACT facilitates access of DME to its targets.
