Translational control of C/EBPα and C/EBPβ isoform expression

Abstract

Transcription factors derived from CCAAT/enhancer binding protein (C/EBP)α and C/EBPβ genes control differentiation and proliferation in a number of cell types. Various C/EBP isoforms arise from unique C/EBPβ and C/EBPα mRNAs by differential initiation of translation. These isoforms retain different parts of the amino terminus and therefore display different functions in gene regulation and proliferation control. We show that PKR and mTOR signaling pathways control the ratio of C/EBP isoform expression through the eukaryotic translation initiation factors eIF-2α and eIF-4E, respectively. An evolutionary conserved upstream open reading frame in C/EBPα and C/EBPβ mRNAs is a prerequisite for regulated initiation from the different translation initiation sites and integrates translation factor activity. Deregulated translational control leading to aberrant C/EBPα and C/EBPβ isoform expression or ectopic expression of truncated isoforms disrupts terminal differentiation and induces a transformed phenotype in 3T3-L1 cells. Our results demonstrate that the translational controlled ratio of C/EBPα and C/EBPβ isoform expression determines cell fate.

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.
