Cytoprotective effects of fucoidan, an algae-derived polysaccharide on 5-fluorouracil-treated dendritic cells

Abstract

Although chemotherapeutic anticancer agents are effective, they also attack normal immune cells due to a lack of selectivity. 5-Fluorouracil (5-FU) is a representative anticancer agent that induces immunosuppression in cancer patients as a side effect. Fucoidan is an algae-derived sulfated polysaccharide that has recently been recognized as a hematopoietic mobilizer and immunomodulator. In this study, we investigated the cytoprotective effect of fucoidan on dendritic cells (DCs) against 5-FU-induced cellular damage. Several kinds of assays including flow cytometric analysis demonstrated the cytoprotective efficacy of fucoidan. In addition, fucoidan increased the expression of immune-related surface markers on and the alloproliferative capacity of DCs exposed to 5-FU. For investigating action mechanism, the expression levels of apoptosis-related molecules were measured. Taken together, the results of this study suggest that fucoidan, a marine-derived polysaccharide, has cytoprotective effects on DCs, the most potent antigen-presenting cell type, against 5-FU-induced cellular damage. These results provide valuable information to use fucoidan as an immunostimulatory agent for the chemotherapy of cancer patients.

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.
