Fucoxanthin (FX), a marine carotenoid, effectively treats stomatitis by reducing inflammation. It works by improving mitochondrial function and inhibiting the cGAS-STING pathway, offering a promising therapeutic option.

Area of Science:

  • Marine natural products
  • Carotenoids
  • Inflammation research

Background:

  • Stomatitis is an inflammatory condition of the oral mucosa.
  • Fucoxanthin (FX), a marine carotenoid, exhibits anti-inflammatory properties.
  • The precise mechanisms of FX's protective effects against stomatitis require elucidation.

Purpose of the Study:

  • To investigate the protective effects of Fucoxanthin (FX) in stomatitis.
  • To elucidate the underlying mechanisms of FX's therapeutic action.

Main Methods:

  • Animal models of 5-fluorouracil (5-FU)-induced oral mucositis.
  • In vitro studies using lipopolysaccharide (LPS)-induced human oral keratinocytes (HOKs).
  • Western blotting, immunofluorescence staining, and molecular docking analyses.

Forskolin-induced Swelling in Intestinal Organoids: An In Vitro Assay for Assessing Drug Response in Cystic Fibrosis Patients

Published on: February 11, 2017

Main Results:

  • FX alleviated oral mucosal damage in 5-FU-induced rats.
  • FX restored tight junction proteins (Occludin, ZO-1), improved mitochondrial function, and inhibited epithelial-mesenchymal transition (EMT) in HOKs.
  • FX downregulated cGAS-STING signaling pathway components (cGAS, STING, TBK1) and showed direct binding to cGAS and STING.

Conclusions:

  • FX ameliorates stomatitis by improving mitochondrial function, reducing mitochondrial DNA release, and inhibiting the cGAS-STING pathway.
  • FX demonstrates potential as a therapeutic agent for stomatitis.
