Abstract

Interleukin-6 is involved in the regulation of many biological activities such as gene expression, cell proliferation, and differentiation. The control of the termination of cytokine signaling is as important as the regulation of initiation of signal transduction pathways. Three families of proteins involved in the down-regulation of cytokine signaling have been described recently: (i) SH2 domain-containing protein-tyrosine phosphatases (SHP), (ii) suppressors of cytokine signaling (SOCS), and (iii) protein inhibitors of activated STATs (PIAS). We have analyzed the interplay of two inhibitors in the signal transduction pathway of interleukin-6 and demonstrate that the tyrosine phosphatase SHP2 and SOCS3 do not act independently but are functionally linked. The activation of one inhibitor modulates the activity of the other; Inhibition of SHP2 activation leads to increased SOCS3-mRNA levels, whereas increased expression of SOCS3 results in a reduction of SHP2 phosphorylation after activation of the interleukin-6 signal transduction pathway. Furthermore, we show that tyrosine 759 in gp130 is essential for both SHP2 and SOCS3 but not for SOCS1 to exert their inhibitory activities on interleukin-6 signal transduction. Besides SHP2, SOCS3 also interacts with the Tyr(P)-759 peptide of gp130. Taken together, our results suggest differences in the function of SOCS1 and SOCS3 and a link between SHP2 and SOCS3.

  • Inhibition of SOCS3 expression or lack of SOCS3 binding sites in gp130 results in sustained STAT3 activation and altered physiological outcomes in response to IL-6.

    “Inhibition of SOCS3 expression [37] or lack of SOCS3 binding sites in gp130 results in sustained STAT3 activation and altered physiological outcomes in response to IL-6 [38].”

    From The tyrosine phosphatase SHP2 increases robustness and information transfer within IL-6-induced JAK/STAT signalling (2021) · cites this paper as [38]

    The introductory passage (page unavailable) says mutation of gp130 Tyr-759 produces enhanced and prolonged STAT3 activation and increased gene induction. The SOCS3-binding discussion (page unavailable) also reports that this mutation impairs SOCS3 inhibition of STAT3 and an acute-phase protein gene promoter. These passages support the signaling and gene-expression findings, but do not establish altered physiological outcomes. (LLM, conf=0.86)

  • Nascent SOCS-3 blocks the activation of STAT-3 by binding to the receptor complex via gp130 at tyrosine 759 and/or by binding and inhibiting Jak2 activity.

    “In the first mechanism, nascent SOCS-3 blocks the activation of STAT-3 by binding to the receptor complex via gp130 at tyrosine 759 (34,35) and/or by binding and inhibiting Jak2 activity (36).”

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.
