Abstract

The receptor subunit gp130 transduces multiple cell type–specific activities of the leukemia inhibitory factor (LIF)/interleukin (IL)-6 family of cytokines through the signal transducer and activator of transcription (STAT) and src homology 2 domain–bearing protein tyrosine phosphatase (SHP)-2/ras/Erk pathways. To define STAT-dependent physiological responses, we generated mice with a COOH-terminal gp130ΔSTAT “knock-in” mutation which deleted all STAT-binding sites. gp130ΔSTAT mice phenocopyed mice deficient for IL-6 (impaired humoral and mucosal immune and hepatic acute phase responses) and LIF (failure of blastocyst implantation). However, unlike mice with null mutations in any of the components in the gp130 signaling pathway, gp130ΔSTAT mice also displayed gastrointestinal ulceration and a severe joint disease with features of chronic synovitis, cartilaginous metaplasia, and degradation of the articular cartilage. Mitogenic hyperresponsiveness of synovial cells to the LIF/IL-6 family of cyto-kines was caused by sustained gp130-mediated SHP-2/ras/Erk activation due to impaired STAT-mediated induction of suppressor of cytokine signaling (SOCS) proteins which normally limits gp130 signaling. Therefore, the joint pathology in gp130ΔSTAT mice is likely to arise from the disturbance of the otherwise balanced activation of the SHP-2/ras/Erk and STAT signaling cascades emanating from gp130.

  • Defective STAT3 activation enhances SHP-2-ERK-MAPK activation pathways, most likely through an impaired STAT3-mediated induction of SOCS3.

    “Similarly, defective STAT3 activation enhances SHP-2–ERK–MAPK activation pathways, most likely through an impaired STAT3-mediated induction of suppressor of cytokine signaling 3 (SOCS3) (111, 112).”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [111]

    The Results section, “Sustained Activation of the SHP-2/ras/Erk Pathway Results from Impaired Induction of SOCS-1” (page unavailable), links impaired STAT signaling to sustained SHP-2/ras/Erk activation and reports reduced SOCS-3 induction. It does not establish the specific STAT3-to-SOCS3 mechanism claimed: it emphasizes SOCS-1 and describes induction of both SOCS-1 and SOCS-3 as mediated at least in part by STATs. (LLM, conf=0.86)

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.
