Intragenic DNA methylation prevents spurious transcription initiation
Open accessAbstract
In mammals, DNA methylation occurs mainly at CpG dinucleotides. Methylation of the promoter suppresses gene expression, but the functional role of gene-body DNA methylation in highly expressed genes has yet to be clarified. Here we show that, in mouse embryonic stem cells, Dnmt3b-dependent intragenic DNA methylation protects the gene body from spurious RNA polymerase II entry and cryptic transcription initiation. Using different genome-wide approaches, we demonstrate that this Dnmt3b function is dependent on its enzymatic activity and recruitment to the gene body by H3K36me3. Furthermore, the spurious transcripts can either be degraded by the RNA exosome complex or capped, polyadenylated, and delivered to the ribosome to produce aberrant proteins. Elongating RNA polymerase II therefore triggers an epigenetic crosstalk mechanism that involves SetD2, H3K36me3, Dnmt3b and DNA methylation to ensure the fidelity of gene transcription initiation, with implications for intragenic hypomethylation in cancer.

Written from the paper’s full text.
TL;DR
Dnmt3b-mediated DNA methylation within gene bodies, recruited via H3K36me3, suppresses spurious intragenic RNA polymerase II entry and cryptic transcription initiation in mouse embryonic stem cells. The resulting aberrant transcripts can be degraded by the RNA exosome or capped, polyadenylated, exported, and ribosome-associated, with possible relevance to intragenic hypomethylation in cancer.
Key findings
- Dnmt3b knockout reduced gene-body 5-methylcytosine, especially on exons and introns, and increased intragenic transcription: 1,445 genes (18% of genes with RPKM > 1) showed an intermediate-exon/first-exon log2 ratio above 1.
- DECAP-seq identified 2,627 high-expression intragenic transcription start sites (RPM > 6) specific to Dnmt3b−/− cells, versus 780 shared and 936 WT-specific sites; Dnmt3b−/−-specific sites accounted for 2.76% of mapped reads, while shared sites accounted for 5.22%.
- SetD2 silencing reduced H3K36me3 and Dnmt3b gene-body binding and produced 3,560 high-confidence intragenic TSSs, of which 2,759 were specific to the knockdown and more than 2,000 overlapped with Dnmt3b−/− sites.
- Rescue experiments showed that wild-type Dnmt3b, but not the catalytically inactive V725G mutant or H3K36me3-binding mutants S277P and VW-RR, reduced the intermediate/first-exon ratio; cryptic RNAs were partly degraded by the RNA exosome, partly polyadenylated, and showed increased ribosome occupancy in intronic regions.
Methods
- Mouse E14 embryonic stem cells were used, with two independent Dnmt3b knockout lines generated by TALEN targeting of exon 17; SetD2, Dis3, and Rrp6 were silenced by shRNA, and Dnmt3b rescue used wild-type or mutant constructs.
- Genome-wide assays included ChIP-seq for Dnmt3b, RNA Pol II, H3K36me3, and other marks; whole-genome bisulfite sequencing; total, polyA+, and cytoplasmic RNA-seq; CAPIP-seq; DECAP-seq for single-base TSS mapping; and ART-seq ribosome profiling.
- Analyses mapped reads to an E14-specific mm9 variant and used TopHat/Cuffdiff, Bowtie, BSMAP, MACS, and custom scripts, with significance assessed by Wilcoxon rank-sum, chi-square, hypergeometric, and correlation tests.
Limitations
- The paper has no dedicated limitations section; it notes that alternative splicing and repetitive-element activation events in Dnmt3b−/− cells were sporadic, with only 4 of 2,563 genes showing intragenic alternative-promoter reactivation.
- The cancer relevance is discussed as an implication rather than tested directly, and the production of aberrant proteins from cryptic transcripts is suggested by ribosome profiling rather than demonstrated.
- Evident from the text: the work is restricted to mouse ESCs and relies heavily on knockout/knockdown and overexpression systems, so the findings may not generalize to other cell types or in vivo tumor settings.

“Of note, Mock ESCs showed higher correlation with Dnmt3b mutant transfected ESCs (r = 0.99) with respect that Dnmt3b WT transfected ESCs (r = 0.95), thus suggesting that DNA methylation enzymatic activity is the major driver of the Dnmt3b-dependent transcriptome alterations.”

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.
A language model drew the claims from the paper on 2026-10-07, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-07 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
