Abstract

The IL-6-triggered positive feedback loop for NFκB signaling (or the IL-6 amplifier/Inflammation amplifier) was originally discovered as a synergistic-activation signal that follows IL-17/IL-6 stimulation in nonimmune cells. Subsequent results from animal models have shown that the amplifier is activated by stimulation of NFκB and STAT3 and induces chemokines and inflammation via an NFκB loop. However, its role in human diseases is unclear. Here, we combined two genome-wide mouse screens with SNP-based disease association studies, revealing 1,700 genes related to the IL-6 amplifier, 202 of which showed 492 indications of association with ailments beyond autoimmune diseases. We followed up on ErbB1 from our list. Blocking ErbB1 signaling suppressed the IL-6 amplifier, whereas the expression of epiregulin, an ErbB1 ligand, was higher in patients with inflammatory diseases. These results indicate that the IL-6 amplifier is indeed associated with human diseases and disorders and that the identified genes may make for potential therapeutic targets.

  • IL-6 is a major player in chronic inflammatory diseases, autoimmune diseases, cancer and cytokine storm.

    “Among them, IL-6 is a major player in chronic inflammatory diseases, autoimmune diseases, cancer and cytokine storm (1, 3, 10–26).”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [10]

    The Introduction describes IL-6 as important in autoimmune diseases and other inflammatory conditions, and the Discussion links the IL-6 amplifier to chronic inflammation in humans. The passages do not support the additional claims about cancer or cytokine storm; searches for those terms found no relevant discussion in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The IL-6 amplifier plays a key role in inflammatory diseases including cytokine storm syndromes, autoimmune diseases and cancer.

    “It too plays a key role in inflammatory diseases including cytokine storm syndromes, autoimmune diseases and cancer (10, 11, 15, 41, 66–68)”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [10]

    The Discussion (page not specified) describes the IL-6 amplifier as important in chronic inflammation and reports associations with autoimmune diseases, including rheumatoid arthritis and lupus. The passages found do not support the added claims about cytokine storm syndromes or cancer. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Enhanced production of epiregulin and TNFα is induced by activation of the IL-6 Amp, and these molecules further activate NF-κB alone or STAT3 as well.

    “In addition, the enhanced production of epiregulin and TNFα is induced by the activation of the IL-6 Amp, and these molecules further activate NF-κB alone or STAT3 as well (10).”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [10]

    The Results report that epiregulin expression increases after IL-6 and IL-17 stimulation and that epiregulin enhances NF-κB activation through the PI3Kα pathway. The available passages do not support the parallel claims about TNFα production or TNFα activating NF-κB or STAT3; searches for TNF and tumor necrosis factor found no relevant passage. Page numbers were not provided. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Target molecules of the IL-6 Amp include EGFR, c-Myc, Pim1, VEGFα, hypoxia-inducible factor 1-alpha, MMPs and many pro-inflammatory cytokines and growth factors involved in cell survival, proliferation, angiogenesis and metastasis.

    “Target molecules of the IL-6 Amp include EGFR, c-Myc, Pim1, VEGFα, hypoxia-inducible factor 1-alpha (HIF1-α), MMPs and many pro-inflammatory cytokines and growth factors involved in cell survival, proliferation, angiogenesis and metastasis (Fig. 3) (10, 11).”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [10]

    The Results report that IL-6 stimulation increased ErbB1 (EGFR) expression, and the Discussion says IL-6 amplifier activation induces chemokines and pro-inflammatory cytokines. Our copy does not substantiate the listed c-Myc, Pim1, VEGFα, HIF1-α, or MMPs as amplifier targets, or the asserted roles in cell survival, proliferation, angiogenesis, and metastasis (searched those terms).

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.
