Abstract

Radiation‐induced oral mucositis is a major adverse event of radiotherapy. Severe oral mucositis may cause unwanted interruption in radiotherapy and reduce long‐term survival in cancer patients receiving radiotherapy, but until now, there have been no effective options for preventing radiation‐induced oral mucositis. Quercetin is a flavonoid that is widely found in food species and has anti‐inflammatory, antioxidant, and anticancer activities. In this study, we investigated a new role of quercetin in preventing radiation‐induced oral mucositis. Quercetin exerted preventive effects against radiation‐induced oral mucositis induced by single‐dose (25 Gy) ionizing radiation or fractionated ionizing radiation (8 Gy × 3) in C57BL/6 mice and maintained the proliferation ability of basal epithelial cells. Quercetin pretreatment alleviated reactive oxygen species generation, NF‐κ B pathway activation, and downstream proinflammatory cytokine production and reduced DNA double‐strand breaks and cellular senescence induced by ionizing radiation. Quercetin also upregulated BMI‐1 expression in oral epithelial cells and promoted ulcer repair. In addition, quercetin exerted similar radioprotective effects in irradiated primary cultured normal human keratinocytes, reduced reactive oxygen species generation and proinflammatory cytokine release, and promoted DNA double‐strand break repair and wound healing by upregulating the expression of BMI‐1, which is a polycomb group protein. Thus, quercetin can block multiple pathological processes of radiation‐induced oral mucositis by targeting BMI‐1 and may be a potential treatment option for preventing radiation‐induced oral mucositis.

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

  • Treatment with quercetin significantly lowers levels of ROS and inflammatory cytokines, reduces expression of SA-β gal, p16 and p53, and markedly increases that of antioxidant enzymes SOD and CAT, regardless of the type of oxidative trigger used to induce senescence.

    “Results obtained on different cell lines show that treatment with quercetin significantly lowers the levels of ROS and inflammatory cytokines, reduces the expression of SA-β gal, p16 and p53 and markedly increases that of the antioxidant enzymes SOD and CAT, regardless of the type of oxidative trigger used to induce senescence [258,259,260,261,262].”
  • Quercetin is a flavonol known for its antioxidant, anti-inflammatory, antitumor, and senolytic properties.

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.
