Abstract

The role of cellular metabolism in regulating cell proliferation and differentiation remains poorly understood. For example, most mammalian cells cannot proliferate without exogenous glutamine supplementation even though glutamine is a non-essential amino acid. Here we show that mouse embryonic stem (ES) cells grown under conditions that maintain naive pluripotency are capable of proliferation in the absence of exogenous glutamine. Despite this, ES cells consume high levels of exogenous glutamine when the metabolite is available. In comparison to more differentiated cells, naive ES cells utilize both glucose and glutamine catabolism to maintain a high level of intracellular α-ketoglutarate (αKG). Consequently, naive ES cells exhibit an elevated αKG to succinate ratio that promotes histone/DNA demethylation and maintains pluripotency. Direct manipulation of the intracellular αKG/succinate ratio is sufficient to regulate multiple chromatin modifications, including H3K27me3 and ten-eleven translocation (Tet)-dependent DNA demethylation, which contribute to the regulation of pluripotency-associated gene expression. In vitro, supplementation with cell-permeable αKG directly supports ES-cell self-renewal while cell-permeable succinate promotes differentiation. This work reveals that intracellular αKG/succinate levels can contribute to the maintenance of cellular identity and have a mechanistic role in the transcriptional and epigenetic state of stem cells.

  • α-KG supports self-renewal of naive murine embryonic stem cells by promoting histone and DNA demethylation.

    “In addition to its role in cancer cells, α-KG supports the self-renewal of naive murine embryonic stem cells (mESCs) by promoting histone and DNA demethylation104.”

  • The effect of αKG on cell fate is likely context specific, as interventions that increase αKG levels in mouse ESCs favor self-renewal over differentiation.

    “However, the effect of αKG on cell fate is likely context specific as interventions that increase αKG levels in mouse ESCs favor self-renewal over differentiation (165, 166).”
  • Naïve mouse ESCs accumulate pools of αKG and acetyl-CoA, which may reinforce the pluripotent state by stimulating more open chromatin.

    “Moreover, naïve mouse ESCs accumulate pools of αKG and acetyl-CoA, which may reinforce the pluripotent state by stimulating more open chromatin (165, 211, 212, 213, 214).”
  • The glutamine-independent phenotype exhibited by naïve mouse ESCs is coupled with a reduction in the contribution of glutamine-derived carbons to TCA cycle intermediates.

    “The glutamine-independent phenotype exhibited by naïve mouse ESCs is coupled with a reduction in the contribution of glutamine-derived carbons to TCA cycle intermediates (165).”
  • Naïve mouse ESCs can grow in the absence of exogenous glutamine.

    “While most cultured cell lines require glutamine supplementation to support cell survival and proliferation, naïve mouse ESCs can grow in the absence of exogenous glutamine.”

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.
