Copy number-dependent DNA methylation of the Pyricularia oryzae MAGGY retrotransposon is triggered by DNA damage

open access: yesCommunications Biology, 2021
Ba Van Vu, Quyet Nguyen et al. investigate the mechanism by which transposable elements are targeted for DNA methylation, using the fungus Pyricularia oryzae as a model system.

The DNA sequence of the transposable element Ac of Zea mays L. [PDF]

open access: yesMolecular and General Genetics MGG, 1984
The sequence of the Ac element isolated from the wx-m7 allele has been determined. The Ac element is 4563 bp long. A central portion of roughly 3.1 kb is occupied by three open reading frames, two of which point in one direction and the third in the opposite direction.

Widespread contribution of transposable elements to the rewiring of mammalian 3D genomes

open access: yesNature Communications, 2023
Here the authors show transposable elements, formerly considered junk DNA, are a source of CTCF binding sites that contribute to species-specific 3D-genome structure, and may impact gene regulation during the course of mammalian evolution.

Shedding light on DNA methylation and its clinical implications: the impact of long-read-based nanopore technology

open access: yesEpigenetics & Chromatin
DNA methylation is an essential epigenetic mechanism for regulation of gene expression, through which many physiological (X-chromosome inactivation, genetic imprinting, chromatin structure and miRNA regulation, genome defense, silencing of transposable ...

DNA methylation dynamics during early plant life

open access: yesGenome Biology, 2017
Background Cytosine methylation is crucial for gene regulation and silencing of transposable elements in mammals and plants. While this epigenetic mark is extensively reprogrammed in the germline and early embryos of mammals, the extent to which DNA ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Proliferation of Regulatory DNA Elements Derived from Transposable Elements in the Maize Genome [PDF]

open access: yesPlant Physiology, 2018
Genomic regions free of nucleosomes, which are hypersensitive to DNase I digestion, are known as DNase I hypersensitive sites (DHSs) and frequently contain cis-regulatory DNA elements. To investigate their prevalence and characteristics in maize (Zea mays), we developed high-resolution genome-wide DHS maps using a modified DNase-seq technique.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Activation of neuronal genes via LINE-1 elements upon global DNA demethylation in human neural progenitors

open access: yesNature Communications, 2019
DNA methylation plays an important role in silencing transposable elements. Here the authors find that loss of DNMT1 and DNA methylation leads to transcriptional activation and chromatin remodelling of evolutionarily young—hominoid-specific —LINE-1 ...
