Activating transcription factor 4-dependent induction of FGF21 during amino acid deprivation

De Sousa-Coelho, Ana Luísa, Marrero, Pedro F., Haro, Diego·2012·Biochemical Journal

Abstract

Nutrient deprivation or starvation frequently correlates with amino acid limitation. Amino acid starvation initiates a signal transduction cascade starting with the activation of the kinase GCN2 (general control non-derepressible 2) phosphorylation of eIF2 (eukaryotic initiation factor 2), global protein synthesis reduction and increased ATF4 (activating transcription factor 4). ATF4 modulates a wide spectrum of genes involved in the adaptation to dietary stress. The hormone FGF21 (fibroblast growth factor 21) is induced during fasting in liver and its expression induces a metabolic state that mimics long-term fasting. Thus FGF21 is critical for the induction of hepatic fat oxidation, ketogenesis and gluconeogenesis, metabolic processes which are essential for the adaptive metabolic response to starvation. In the present study, we have shown that FGF21 is induced by amino acid deprivation in both mouse liver and cultured HepG2 cells. We have identified the human FGF21 gene as a target gene for ATF4 and we have localized two conserved ATF4-binding sequences in the 5′ regulatory region of the human FGF21 gene, which are responsible for the ATF4-dependent transcriptional activation of this gene. These results add FGF21 gene induction to the transcriptional programme initiated by increased levels of ATF4 and offer a new mechanism for the induction of the FGF21 gene expression under nutrient deprivation.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • The Fgf21 promoter has multiple ATF4 binding sites, and GCN2-mediated activation of ATF4 leads to induction of hepatic and circulating FGF21.

    “The Fgf21 promoter has multiple ATF4 binding sites, and GCN2-mediated activation of ATF4 leads to the induction of hepatic and circulating levels of FGF21 (24, 68, 72).”
  • FGF21 is also increased by the restriction of individual amino acids.

    “with FGF21 also being increased by the restriction of individual amino acids”

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.
