Smad3 and Smad4 cooperate with c-Jun/c-Fos to mediate TGF-β-induced transcription

Zhang, Ying, Feng, Xin-Hua, Derynck, Rik·1998·Nature

Abstract

Smad proteins transduce signals for transforming growth factor-beta (TGF-beta)-related factors. Smad proteins activated by receptors for TGF-beta form complexes with Smad4. These complexes are translocated into the nucleus and regulate ligand-induced gene transcription. 12-O-tetradecanoyl-13-acetate (TPA)-responsive gene promoter elements (TREs) are involved in the transcriptional responses of several genes to TGF-beta (refs 5-8). AP-1 transcription factors, composed of c-Jun and c-Fos, bind to and direct transcription from TREs, which are therefore known as AP1-binding sites. Here we show that Smad3 interacts directly with the TRE and that Smad3 and Smad4 can activate TGF-beta-inducible transcription from the TRE in the absence of c-Jun and c-Fos. Smad3 and Smad4 also act together with c-Jun and c-Fos to activate transcription in response to TGF-beta, through a TGF-beta-inducible association of c-Jun with Smad3 and an interaction of Smad3 and c-Fos. These interactions complement interactions between c-Jun and c-Fos, and between Smad3 and Smad4. This mechanism of transcriptional activation by TGF-beta, through functional and physical interactions between Smad3-Smad4 and c-Jun-c-Fos, shows that Smad signalling and MAPK/JNK signalling converge at AP1-binding promoter sites.

Recomputing p-values needs the paper’s full text.

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 enrichment of Fos/Jun motifs results in the transcriptional upregulation of classic effectors in this signaling pathway, such as SMAD3, SMAD4, TGFB1, and DDIT3.

    “Conversely, the enrichment of Fos/Jun motifs results in the transcriptional upregulation of classic effectors in this signaling pathway, such as SMAD3, SMAD4, TGFB1, and DDIT3 (Zhang 1998)47.”

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.
