A Tail-Based Mechanism Drives Nucleosome Demethylation by the LSD2/NPAC Multimeric Complex

open access: yesCell Reports, 2019
Summary: LSD1 and LSD2 are homologous histone demethylases with opposite biological outcomes related to chromatin silencing and transcription elongation, respectively.

Histone demethylase IBM1-mediated meiocyte gene expression ensures meiotic chromosome synapsis and recombination.

open access: yesPLoS Genetics, 2022
Histone methylation and demethylation play important roles in plant growth and development, but the involvement of histone demethylation during meiosis is poorly understood.

PHF2 regulates homology-directed DNA repair by controlling the resection of DNA double strand breaks [PDF]

open access: yes, 2020
Post-translational histone modifications and chromatin remodelling play a critical role controlling the integrity of the genome. Here, we identify histone lysine demethylase PHF2 as a novel regulator of the DNA damage response by regulating DNA damage ...

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

open access: yesAdvanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

The enzymes LSD1 and Set1A cooperate with the viral protein HBx to establish an active hepatitis B viral chromatin state [PDF]

open access: yes, 2016
Indexación: Web of ScienceWith about 350 million people chronically infected around the world hepatitis B is a major health problem. Template for progeny HBV synthesis is the viral genome, organized as a minichromosome (cccDNA) inside the hepatocyte ...

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

A Histone Acetyltransferase Regulates Active DNA Demethylation in Arabidopsis [PDF]

open access: yesScience, 2012
To Silence or Not to Silence Repressed genes commonly have methylated DNA, and/or covalent histone modifications associated with silent chromatin, and/or associated small interfering (si)RNAs. All three features are components of gene-silencing systems (see the Perspective by Jacob and Martienssen

Positioning of nucleosomes containing γ-H2AX precedes active DNA demethylation and transcription initiation

open access: yesNature Communications, 2021
The order of DNA methylation and histone modifications during transcription remained unclear. Here the authors show that HMGA2 induces DNA nicks at TGFB1-responsive genes, promoting nucleosome incorporation containing γ-H2AX, which is required for repair-

Targeting the Mapk13‐Tcf1‐Slc7a5 Axis via One‐Carbon Metabolic Regulation to Prevent Chronic Allograft Vasculopathy

open access: yesAdvanced Science, EarlyView.
This study emphasizes the role of the Mapk13‐Tcf1‐Slc7a5‐methionine metabolism axis in stem‐like CD4+ T cells. Moreover, it uncovers the mechanism through which limiting one‐carbon metabolism in CD4+ stem‐like T cells suppresses the tide of chronic allograft vasculopathy, offering potential targets to promote long‐term graft survival.
