Abstract

Background Trefoil factor family 1 (TFF1) is a member of the TFF-domain peptide family involved in epithelial restitution and cell motility. Recently, we screened Piezo1 as a candidate TFF1-binding protein. Aim We aimed to confirm Piezo1 as a novel TFF1 binding protein and to assess the role of this interaction in mediating gastric cancer cell mobility. Methods This interaction was confirmed by co-immunoprecipitation and co-localisation of TFF1 and Piezo1 in GES-1 cells. We used stable RNA interference to knockdown Piezo1 protein expression and restored the expression of TFF1 in the gastric cancer cell lines SGC-7901 and BGC-823. Cell motility was evaluated using invasion assay and migration assay in vitro. The expression levels of the integrin subunits β1, β5, α1 as well as the expression of β-catenin and E-cadherin were detected by Western blot. Results We demonstrate that TFF1, but not TFF2 or TFF3, bind to and co-localize with Piezo1 in the cytoplasm in vitro. TFF1 interacts with the C-terminal portion of the Piezo1 protein. Wound healing and trans-well assays demonstrated that the restored expression of TFF1 promoted cell mobility in gastric cancer cells, and this effect was attenuated by the knockdown of Piezo1. Western blots demonstrated the decreased expression of integrin β1 in Piezo1-knockdown cells. Conclusions Our data demonstrate that Piezo1 is a novel TFF1 binding protein that is important for TFF1-mediated cell migration and suggest that this interaction may be a therapeutic target in the invasion and metastasis of gastric cancer.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In vitro, Piezo1 reduces the migratory ability of gastric cancer cells by downregulating integrin β subunits.

    “In vitro, Piezo1 has been shown to reduce the migratory ability of gastric cancer cells by downregulating integrin β subunits.108”
  • In other cancers, such as NSCLC and gastric cancer, Piezo1 expression is often reduced and has been shown to inhibit cell migration and metastasis, potentially via integrin-mediated and Hippo-pathway-related mechanisms.

    “Conversely, in other cancers, such as non-small cell lung carcinoma and gastric cancer, Piezo1 expression is often reduced and has been shown to inhibit cell migration and metastasis, potentially via integrin-mediated and Hippo-pathway-related mechanisms.”
  • Gastric cancer exhibits a distinct integrin-Piezo1-FAK axis, with rigidity-induced FAK phosphorylation enhancing migration.

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.
