High-resolution analysis of cytosine methylation in ancient DNA. [PDF]

PLoS ONE, 2012
Epigenetic changes to gene expression can result in heritable phenotypic characteristics that are not encoded in the DNA itself, but rather by biochemical modifications to the DNA or associated chromatin proteins. Interposed between genes and environment,

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis

Molecular Oncology, EarlyView.
This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected

In planta assays involving epigenetically silenced genes reveal inhibition of cytosine methylation by genistein

Plant Methods, 2012
Background Cytosine methylation is involved in epigenetic control of gene expression in a wide range of organisms. An increasing number of examples indicate that changing the frequency of cytosine methylation in the genome is a feasible tool to engineer ...

Cytosine methylation alters DNA mechanical properties [PDF]

Nucleic Acids Research, 2011
DNA methylation plays an essential role in transcriptional control of organismal development in epigenetics, from turning off a specific gene to inactivation of entire chromosomes. While the biological function of DNA methylation is becoming increasingly clear, the mechanism of methylation-induced gene regulation is still poorly understood.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Increasing TET Expression and 5‐Hydroxymethylcytosine Formation by a Carbocyclic 5‐Aza‐2′‐deoxy‐cytidine Antimetabolite

Angewandte Chemie, EarlyView.
The carbocyclic Decitabine analog (cAzadC) incorporates as an antimetabolite weakly into the genome of growing tumor cells, where it triggers a genome‐wide demethylation and a surprisingly strong hydroxymethylation of cytosine, which translates into an efficient in vivo antitumor (AML) effect.

A Molecular Cloning and Sanger Sequencing-based Protocol for Detecting Site-specific DNA Methylation

Bio-Protocol, 2022
DNA methylation is a conserved chemical modification, by which methyl groups are added to the cytosine of DNA molecules. Methylation can influence gene expression without changing the sequence of a particular gene. This epigenetic effect is an intriguing
