Eicosapentaenoic acid induces DNA demethylation in carcinoma cells through a TET1-dependent mechanism [PDF]
In cancer cells, global genomic hypomethylation is found together with localized hypermethylation of CpG islands within the promoters and regulatory regions of silenced tumor suppressor genes.

Sequence-selective 5-methylcytosine oxidation for epigenotyping [PDF]
Methylation of DNA is an epigenetic modification that can play an important role in the control of gene expression in mammalian cells. The development of a simple and convenient method for site-specific discrimination of cytosine methylation is imperative for genomic studies.

Methylating RNA post‐transcriptionally is emerging as a significant mechanism of gene regulation in eukaryotes. The crosstalk between RNA methylation and histone modification is critical for chromatin state and gene expression in mammals.

Protein Interactions at Oxidized 5-Methylcytosine Bases
5-Methylcytosine (5mC), the major modified DNA base in mammalian cells, can be oxidized enzymatically to 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5-carboxylcytosine (5caC) by the Ten-Eleven-Translocation (TET) family of proteins.

Oxygenase Catalyzed 5-Methylcytosine Hydroxylation
Recent reports identify the oxygenase catalyzed production of 5-hydroxymethylcytosine as a modification to mammalian DNA (Kriaucionis and Heintz, 2009; Tahiliani et al., 2009). This discovery has potential far-reaching implications for epigenetic regulation and will stimulate efforts to identify new nucleic acid modifications.

Discovery of a Bacterial 5-Methylcytosine Deaminase [PDF]
5-Methylcytosine is found in all domains of life, but the bacterial cytosine deaminase from Escherichia coli (CodA) will not accept 5-methylcytosine as a substrate. Since significant amounts of 5-methylcytosine are produced in both prokaryotes and eukaryotes, this compound must eventually be catabolized and the fragments recycled by enzymes that have ...

UHRF2 regulates local 5-methylcytosine and suppresses spontaneous seizures
The 5-methylcytosine (5mC) modification regulates multiple cellular processes and is faithfully maintained following DNA replication. In addition to DNA methyltransferase (DNMT) family proteins, ubiquitin-like PHD and ring finger domain-containing ...

Theoretical and experimental study of the vibrational spectra of 1.5-dimethylcytosine [PDF]
The Raman spectra of the solid 1,5-dimethylcytosine and the FTIR spectra at room and low temperatures respectively have been registered. Quantum mechanical calculations of energies, geometries and vibrational wavenumbers were carried out by using ab ...

Characterizing 5-methylcytosine in the mammalian epitranscriptome [PDF]
The post-transcriptional modification 5-methylcytosine (m5C) occurs in a wide range of coding and non-coding RNAs. We describe transcriptome-wide approaches to capture the global m5C RNA methylome. We also discuss the potential functions of m5C in RNA and compare them to 6-methyladenosine modifications.

DNA 5-Methylcytosine-Specific Amplification and Sequencing
DNA 5-methylcytosine (5mC)-specific mapping has been hampered by severe DNA degradation and the presence of 5-hydroxymethylcytosine (5hmC) using the conventional bisulfite sequencing approach. Here, we present a 5mC-specific whole-genome amplification method (5mC-WGA), with which we achieved 5mC retention during DNA amplification from limited input ...
