Quantitative Sequencing of 5-Methylcytosine and 5-Hydroxymethylcytosine at Single-Base Resolution

Abstract

Distinguishing Epigenetic Marks: Methylation of the cytosine base in eukaryotic DNA (5mC) is an important epigenetic mark involved in gene silencing and genome stability. Methylated cytosine can be enzymatically oxidized to 5-hydroxymethylcytosine (5hmC), which may function as a distinct epigenetic mark—possibly involved in pluripotency—and it may also be an intermediate in active DNA demethylation. To be able to detect 5hmC genome-wide and at single-base resolution, Booth et al. (p. 934 , published online 26 April) developed a 5hmC sequencing chemistry that selectively oxidizes 5hmC to 5-formylcytosine and then to uracil while leaving 5mC unchanged. Using this method, mouse embryonic stem cell genomic DNA was sequenced to reveal that 5hmC is found enriched at intragenic CpG islands and long interspersed nuclear element–1 retrotransposons.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
