ATP-Citrate Lyase Links Cellular Metabolism to Histone Acetylation

Open access

Abstract

Chromatin Modifier Modulates Gene Expression: Modification of chromatin structure is usually thought of as a global, relatively nonspecific way of modulating gene expression. However, Wellen et al. (p. 1076 ; see the Perspective by Rathmell and Newgard ) demonstrate that such regulation helps link growth factor–stimulated increases in metabolism to appropriate changes in gene expression. Adenosine triphosphate (ATP)–citrate lyase (ACL), which converts citrate to acetyl–coenzyme A (CoA) in the mitochondria of mammalian cells during metabolism of glucose, was also found to be present in the nucleus, where it might regulate activity of histone acetyl transferases (HATs) by controlling the availability of acetyl-CoA. Indeed, depletion of ACL from cultured human colon carcinoma cells specifically decreased histone acetylation in the nucleus, but appeared not to affect the overall amount of acetylation of proteins in the cells. Loss of ACL in cultured mouse 3T3-L1 cells diminished the increase in histone acetylation normally associated with hormone-stimulated differentiation of these cells and inhibited the increase in expression of specific genes, such as that encoding the Glut4 glucose transporter. Thus, ACL may help cells link metabolic activity to changes in gene expression.

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.
