Mast cells participate in allergy and inflammation by secreting inflammatory mediators such as histamine and proinflammatory cytokines. Flavonoids are naturally occurring molecules with antioxidant, cytoprotective, and antiinflammatory actions. However, effect of flavonoids on the release of histamine and proinflammatory mediator, and their comparative(More)
Epithelial-mesenchymal transition (EMT) is the process by which epithelial cells become mesenchymal cells, gaining fibroblast-like properties and displaying reduced intercellular adhesion and increased motility. EMT plays an important role in cancer metastasis. Suppressing or reversing EMT is therefore an important way of controlling various cancers.(More)
Although the cytotoxicity of nanoparticles (NPs) is greatly influenced by their interactions with blood proteins, toxic effects resulting from blood interactions are often ignored in the development and use of nanostructured biomaterials for in vivo applications. Protein coronas created during the initial reaction with NPs can determine the subsequent(More)
ETHNOPHARMACOLOGICAL RELEVANCE The Lindera obtusiloba has been used in traditional medicine for the treatment of inflammation and dermatitis. In this study, we investigated the effect of topical application of Lindera obtusiloba water extract (LOWE) on the house dust mite extract (Dermatophagoides farinae extract, DFE) and 2,4-dinitrochlorobenzene(More)
UNLABELLED CCL20 expression is known to increase in the mucosal tissues of inflammatory bowel diseases (IBDs). Moreover, the discovery of Nod2 as the IBD1 susceptibility gene has underscored the significance of blood mononuclear cells in IBD pathogenesis. METHODS This study addresses whether CCL20 expression is similarly altered in peripheral blood(More)
We investigated the effect of Ecklonia cava (E. cava)-derived dieckol on movement behavior and the expression of migration-related genes in MCF-7 human breast cancer cell. Phlorotannins (e.g., dieckol, 6,6'-biecko, and 2,7″-phloroglucinol-6,6'-bieckol) were purified from E. cava by using centrifugal partition chromatography. Among the phlorotannins, we(More)
AIMS Eupatilin (5,7-dihydroxy-3,4,6-trimethoxyflavone) is a pharmacologically active ingredients in Stillen(TM), a drug for the gastric mucosal ulcers. Eupatilin has been known to possess anti-peptic, anti-cancer, and anti-allergy activity. In this report, we defined the effect of eupatilin on the endotoxin-induced inflammation in lipopolysaccharide(More)
Glycyrrhiza uralensis (Leguminosae) has long been known as an antiinflammatory agent for gastric ulcers, arthritis, and rheumatism. The flavonoid glycyrol (GC) (10 microg/ml) isolated from G. uralensis dramatically inhibits phorbol ester (phorbol 12-myristate 13-acetate)-induced nuclear factor (NF)-kappaB-dependent transcriptional activity, as determined by(More)
DA-9601 (Stillen™) is a novel anti-peptic formulation prepared from the ethanol extracts of Artemisia asiatica possessing anti-oxidative, anti-allergic and anti-inflammatory activities. However, their effect on atopic dermatitis (AD) has not been studied yet. In this study, we report that topical application of DA-9601 suppressed house dust mite extract(More)
We have shown that the bacterial iron chelator, deferoxamine (DFO), triggers inflammatory signals including the production of CXC chemokine IL-8, in human intestinal epithelial cells (IECs) by activating the ERK1/2 and p38 kinase pathways. In this study we investigated the mechanisms involved in IL-8 generation by DFO, focusing on the transcription factors(More)
