Abstract

Intracellular energy balance is important for cell survival. In eukaryotic cells, the most energy-consuming process is ribosome biosynthesis, which adapts to changes in intracellular energy status. However, the mechanism that links energy status and ribosome biosynthesis is largely unknown. Here, we describe eNoSC, a protein complex that senses energy status and controls rRNA transcription. eNoSC contains Nucleomethylin, which binds histone H3 dimethylated Lys9 in the rDNA locus, in a complex with SIRT1 and SUV39H1. Both SIRT1 and SUV39H1 are required for energy-dependent transcriptional repression, suggesting that a change in the NAD(+)/NADH ratio induced by reduction of energy status could activate SIRT1, leading to deacetylation of histone H3 and dimethylation at Lys9 by SUV39H1, thus establishing silent chromatin in the rDNA locus. Furthermore, eNoSC promotes restoration of energy balance by limiting rRNA transcription, thus protecting cells from energy deprivation-dependent apoptosis. These findings provide key insight into the mechanisms of energy homeostasis in cells.

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.
