Abstract

We investigate the role of β-catenin signaling in the response of macrophage to lipopolysaccharide (LPS) using RAW264.7 cells. LPS rapidly stimulated cytosolic β-catenin accumulation. β-catenin-mediated transcription was showed to be required for LPS induced gene expression and cell migration. Mechanically, ERK activation-primed GSK3β inactivation by Akt was demonstrated to mediate the LPS induced β-catenin accumulation. Overall, our findings suggest that suppression of GSK3β by ERK stimulates β-catenin signaling therefore contributes to LPS induced cell migration in macrophage activation.

  • Inactivation of GSK3β disrupts the destruction complex, preventing β-catenin phosphorylation, leading to accumulation of unphosphorylated stable β-catenin, nuclear translocation, and activation of target genes including c-Myc and Cyclin D1.

    “The inactivation of GSK3β disrupts the integrity and function of the destruction complex, thereby preventing β-catenin phosphorylation. As a result, unphosphorylated, stable β-catenin accumulates in the cytoplasm, translocates to the nucleus, and activates the transcription of its target genes, including c-Myc and Cyclin D1 [35, 46, 47, 52–55].”

    The Introduction (page unavailable) says that GSK3β activity promotes β-catenin phosphorylation and degradation, while blocking that activity allows cytosolic β-catenin to accumulate, enter the nucleus, and activate target genes. The transcription-results section identifies c-Myc as a β-catenin-responsive gene, but our copy does not identify Cyclin D1 as a target or say that GSK3β inactivation disrupts the destruction complex’s integrity.

  • A well-established mechanism for ERK/Wnt crosstalk involves direct regulation of GSK3β, the master kinase of the β-catenin destruction complex.

    “A well-established mechanism for this crosstalk involves the direct regulation of Glycogen Synthase Kinase 3β (GSK3β), the master kinase of the β-catenin destruction complex [46–51].”

    From PPP1R18-mediated activation of Wnt/β-catenin and EMT is dependent on ERK signaling in clear cell renal cell carcinoma (2026) · cites this paper as [47]

    The section “Activated ERK associates with and primes GSK3β inactivation by AKT in response to LPS” reports ERK–GSK3β association and subsequent GSK3β inactivation in LPS-treated macrophages. The Introduction identifies GSK3β as part of the complex that phosphorylates β-catenin for degradation. The paper supports this route of crosstalk, but describes ERK as facilitating inactivation by AKT rather than establishing direct ERK-mediated inactivation as a general, well-established mechanism.

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.
