Abstract

Fucoidan, a sulfated polysaccharide extracted from brown seaweeds, has anticoagulant and antithrombotic activities. Unlike heparine, fucoidan is known to exhibit anticarcinogenic activities. However, the underlying molecular mechanisms of the chemopreventive activities of fucoidan are not understood. Here we report that fucoidan from Laminaria cichorioides inhibited the epidermal growth factor (EGF) or 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced neoplastic cell transformation, but had less cytotoxic effects on JB6 mouse epidermal cells. The EGF-induced phosphorylation of extracellular signal-regulated kinases 1/2 and c-Jun N-terminal kinases, and c-Jun was inhibited by fucoidan, resulting from the inhibition of phosphorylation of epidermal growth factor receptor (EGFR). Fucoidan dose-dependently attenuated the c-fos or c-jun transcriptional activity, and thereby inhibited the associated activator protein-1 (AP-1) transactivation activity. In vitro binding assay revealed that fucoidan directly interacted with EGF, suggested that antitumor promoting effect of fucoidan might be due to preventing the binding of EGF to its cell surface receptor (EGFR). These findings are the first to reveal a molecular basis for the anticarcinogenic action of fucoidan and may partially account for the reported chemopreventive effects of brown seaweeds.

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

  • Anticarcinogenic action of fucoidan from S. cichorioides is connected with its ability to interact directly with EGF and prevent its binding to EGFR.

    “It has been suggested that the anticarcinogenic action of fucoidan from S. cichorioides is connected with its ability to interact directly with epidermal growth factor (EGF) and prevents its binding to EGF receptor (EGFR).”
  • In experiments with neoplastic transformation of JB6 mouse epidermal cells induced by EGF or TPA, inhibition of EGFR phosphorylation was followed by inhibition of some ERK activities, resulting in inhibition of AP-1 nuclear factor transactivation.

    “Actually, in experiments with neoplastic transformation of JB6 mouse epidermal cells induced by EGF or 12-O-tetradecanoylphorbol-13 acetate, a Russian-Korean group of scientists reported that inhibition of EGFR phosphorylation was followed by inhibition of the activities of some extracellular signal regulated kinases that resulted in the inhibition of AP-1 nuclear factor transactivation [66,67].”

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.
