Abstract

Histone acetylation plays important roles in gene regulation, DNA replication, and the response to DNA damage, and it is frequently deregulated in tumors. We postulated that tumor cell histone acetylation levels are determined in part by changes in acetyl coenzyme A (acetyl-CoA) availability mediated by oncogenic metabolic reprogramming. Here, we demonstrate that acetyl-CoA is dynamically regulated by glucose availability in cancer cells and that the ratio of acetyl-CoA:coenzyme A within the nucleus modulates global histone acetylation levels. In vivo, expression of oncogenic Kras or Akt stimulates histone acetylation changes that precede tumor development. Furthermore, we show that Akt's effects on histone acetylation are mediated through the metabolic enzyme ATP-citrate lyase and that pAkt(Ser473) levels correlate significantly with histone acetylation marks in human gliomas and prostate tumors. The data implicate acetyl-CoA metabolism as a key determinant of histone acetylation levels in cancer cells.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Citrate export to the cytosol and subsequent cleavage by ACL provides a major source of cytosolic acetyl-CoA that is the obligate substrate for both de novo lipid synthesis and protein acetylation reactions.

    “However, citrate export to the cytosol and subsequent cleavage by ACL provides a major source of cytosolic acetyl-CoA that is the obligate substrate for both de novo lipid synthesis and protein acetylation reactions (39, 187, 188).”
  • Oncogenic activation of the PI3K-AKT signaling axis increases acetyl-CoA levels and promotes elevated histone acetylation both in vitro and in tumors.

    “Accordingly, oncogenic activation of the PI3K–AKT signaling axis increases acetyl-CoA levels and promotes elevated histone acetylation both in vitro and in tumors (188).”
  • Immunohistochemical analysis of glioblastoma and prostate tumor samples shows Akt activation levels closely correlate with global histone acetylation status.

    “Immunohistochemical analysis of glioblastoma and prostate tumor samples has shown that Akt activation levels closely correlate with global histone acetylation status (Lee et al., 2014).”

  • Glucose- and oncogene-driven increases in global histone acetylation are blocked by ACLY inhibition.

    “Furthermore, studies have shown that both the glucose- and oncogene-driven increases in global histone acetylation are blocked by ACLY inhibition (Lee et al., 2014; Wellen et al., 2009).”

  • Withdrawal and readdition of glucose, and activation of oncogenic KRAS or Akt, increase total histone acetylation, promoting enhanced and broader gene expression.

    “Indeed, withdrawal and readdition of glucose, as well as activation of oncogenic signaling via introduction of an oncogenic KRAS mutant or a constitutively active form of Akt, increase total histone acetylation, which, in turn, promotes the enhanced and broader gene expression (Lee et al., 2014).”

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.
