Abstract

TET family enzymes convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) in DNA. Here, we show that Tet1 and Tet2 are Oct4-regulated enzymes that together sustain 5hmC in mouse embryonic stem cells (ESCs) and are induced concomitantly with 5hmC during reprogramming of fibroblasts to induced pluripotent stem cells. ESCs depleted of Tet1 by RNAi show diminished expression of the Nodal antagonist Lefty1 and display hyperactive Nodal signaling and skewed differentiation into the endoderm-mesoderm lineage in embryoid bodies in vitro. In Fgf4- and heparin-supplemented culture conditions, Tet1-depleted ESCs activate the trophoblast stem cell lineage determinant Elf5 and can colonize the placenta in midgestation embryo chimeras. Consistent with these findings, Tet1-depleted ESCs form aggressive hemorrhagic teratomas with increased endoderm, reduced neuroectoderm, and ectopic appearance of trophoblastic giant cells. Thus, 5hmC is an epigenetic modification associated with the pluripotent state, and Tet1 functions to regulate the lineage differentiation potential of ESCs.

  • Tet1 and Tet2, but not Tet3, were upregulated by OSK.

    “Because Tet1 and Tet2, but not Tet3, were upregulated by OSK35,36 (Extended Data Fig. 6a), we tested the effect of knocking down Tet1 or Tet2 (sh-Tet1 or sh-Tet2) using AAV37 in the context of damaged, OSK-treated RGCs (Extended Data Fig. 6b–d).”

    From Reprogramming to recover youthful epigenetic information and restore vision (2020) · cites this paper as [35]

    The Results section reports that Tet1 and Tet2 expression increased, while Tet3 expression decreased, when mouse fibroblasts were reprogrammed to iPS cells. However, the paper used Oct4, Sox2, Klf4 and c-Myc (OSKM), not OSK alone, so it does not establish the claimed response to OSK. (LLM, conf=0.87)

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.
