5-Hydroxymethylcytosine (5-hmC) Specific Enrichment.
5-Hydroxymethylcytosine (5-hmC) is a newly discovered DNA modification in mammalian genomes. This protocol is to be a highly efficient and selective chemical approach to label and capture 5-hmC, taking advantage of a bacteriophage enzyme that adds a glucose moiety to 5-hmC specifically, which could in turn be used for high-throughput mapping via next-generation sequencing.
متن کاملDecreased 5-Hydroxymethylcytosine (5-hmC) predicts poor prognosis in early-stage laryngeal squamous cell carcinoma.
Accumulating evidences suggest that large-scale loss of 5-hydroxymethylcytosine (5-hmC) is an epigenetic hallmark in different cancers. However, the levels of 5-hmC in laryngeal squamous cell carcinoma (LSCC) and its prognostic value in this cancer remain largely unknown. Using dot-blot and quantitative RT-PCR assays, we investigate 5-hmC levels and expression of TET-1, -2 and -3 in LSCCs and e...
متن کاملSpecies-Specific 5 mC and 5 hmC Genomic Landscapes Indicate Epigenetic Contribution to Human Brain Evolution
Human evolution from non-human primates has seen substantial change in the central nervous system, with the molecular mechanisms underlying human brain evolution remaining largely unknown. Methylation of cytosine at the fifth carbon (5-methylcytosine; 5 mC) is an essential epigenetic mark linked to neurodevelopment, as well as neurological disease. The emergence of another modified form of cyto...
متن کاملCharacterization of the 5-hydroxymethylcytosine-specific DNA restriction endonucleases
In T4 bacteriophage, 5-hydroxymethylcytosine (5hmC) is incorporated into DNA during replication. In response, bacteria may have developed modification-dependent type IV restriction enzymes to defend the cell from T4-like infection. PvuRts1I was the first identified restriction enzyme to exhibit specificity toward hmC over 5-methylcytosine (5mC) and cytosine. By using PvuRts1I as the original me...
متن کاملTissue-Specific Differences in DNA Modifications (5-Hydroxymethylcytosine, 5-Formylcytosine, 5-Carboxylcytosine and 5-Hydroxymethyluracil) and Their Interrelationships
BACKGROUND Replication-independent active/enzymatic demethylation may be an important process in the functioning of somatic cells. The most plausible mechanisms of active 5-methylcytosine demethylation, leading to activation of previously silenced genes, involve ten-eleven translocation (TET) proteins that participate in oxidation of 5-methylcytosine to 5-hydroxymethylcytosine which can be furt...
