Tet proteins: on track towards DNA demethylation?
Dynamic DNA methylation is a prerequisite for many developmental processes and maintenance of cellular integrity. In mammals however, mechanisms of active DNA demethylation have for long been elusive.

Epigenetic Down-Regulation of Sirt 1 via DNA Methylation and Oxidative Stress Signaling Contributes to the Gestational Diabetes Mellitus-Induced Fetal Programming of Heart Ischemia-Sensitive Phenotype in Late Life. [PDF]
Rationale: The incidence of gestational diabetes mellitus (GDM) is increasing worldwide. However, whether and how GDM exposure induces fetal programming of adult cardiac dysfunctional phenotype, especially the underlying epigenetic molecular mechanisms ...

NSUN2 introduces 5-methylcytosines in mammalian mitochondrial tRNAs
Abstract Expression of human mitochondrial DNA is indispensable for proper function of the oxidative phosphorylation machinery. The mitochondrial genome encodes 22 tRNAs, 2 rRNAs and 11 mRNAs and their post-transcriptional modification constitutes one of the key regulatory steps during mitochondrial gene expression.

Biomaterial Physical Cues as Gene Regulators for Cellular Agriculture
This review elucidates how biomaterial physical cues—ranging from matrix stiffness to remote electromagnetic fields—serve as extrinsic regulators of gene expression in cellular agriculture. By identifying central mechanotransduction pathways that bridge physical inputs to genetic remodeling, the authors propose the “Material Genome” concept: a ...

Oxidative Stress and DNA Epigenetic Modifications in Cancer: Mechanisms and Targeted Therapeutics
Reactive oxygen species (ROS) modulate DNA methyltransferases (DNMTs), ten‐eleven translocation family proteins (TETs) and their cofactors, reshaping 5‐methylcytosine (5mC)/5‐hydroxymethylcytosine (5hmC)/5‐formylcytosine (5fC) landscapes and gene expression in cancer cells. In turn, epigenetic control of antioxidant and metabolic pathways feeds back on

Targeting EZH2 in Cancer: From Molecular Mechanisms to Clinical Translation
The abnormal overexpression or gain‐of‐function mutations of EZH2 play a significant role in cancer occurrence and progression, highlighting the importance and potential of EZH2 as a cancer biomarker. Therefore, screening for effective and safe small‐molecule inhibitors, degraders, and natural compounds targeting EZH2 through preclinical cancer models ...

Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially
