Casticin alleviates lipopolysaccharide-induced inflammatory responses and expression of mucus and extracellular matrix in human airway epithelial cells through Nrf2/Keap1 and NF-κB pathways.
    Phytotherapy research : PTR, 2018, Volume: 32, Issue:7

    Asthma is one of the most common chronic inflammatory diseases of childhood, characterized by airway inflammation, mucus hypersecretion, and accumulation of extracellular matrix proteins. Casticin is an active compound that possesses broad biological activities including anti-inflammatory effect. However, the effect of casticin on asthma remains unknown. The aim of the present study was to evaluate the effect and mechanism of casticin on inflammatory responses and expression of mucus and extracellular matrix in human airway epithelial cells. The results showed that lipopolysaccharide induced the mRNA and protein levels of IL-6, IL-8, MUC5AC, collagen type I, and fibronectin in 16-HBE cells, whereas casticin treatment significantly inhibited the induction of lipopolysaccharide. Casticin induced Nrf2/Keap1 and inhibited nuclear factor κB pathways in 16-HBE cells. Knockdown of Nrf2 attenuated the effect of casticin on production of IL-6 and IL-8, expression of MUC5AC, collagen type I, and fibronectin in 16-HBE cells. In conclusion, the results indicated that casticin might be a novel therapeutic strategy for the treatment of asthma.

Inhibitory effects of casticin on migration of eosinophil and expression of chemokines and adhesion molecules in A549 lung epithelial cells via NF-κB inactivation.
    Journal of ethnopharmacology, 2011, Jul-14, Volume: 136, Issue:3

    The fruits of Vitex rotundifolia L. have long been used for the treatment of inflammation of the respiratory tract in East Asia.. To determine if casticin, one of the constituents of Vitex rotundifolia L., has anti-allergic and anti-inflammatory effects in asthma.. The in vitro anti-inflammatory activity of casticin was studied in A549 human type II-like epithelial lung cells using an eotaxin inhibition assay. Additionally, its effects on eotaxin, regulated on activation normal T cell expressed and secreted (RANTES), vascular cell adhesion molecule (VCAM)-1, and inter-cellular adhesion molecule (ICAM)-1 expression were investigated by real time-polymerase chain reaction (real time-PCR). The inhibition of nuclear factor κB (NF-κB) activity in the presence of casticin was determined by analyzing confocal microscopy images of fluorescence immunocytochemical analysis while the suppression of inhibitory κB (IκB)-α phosphorylation was studied using Western blot analysis. Finally, the inhibitory effect of casticin on eosinophil migration toward prestimulated A549 cell media was measured using the human eosinophilic leukemia cell line.. Casticin significantly suppressed eotaxin production in cytokine activated A549 lung epithelial cells. Casticin also suppressed the mRNA expression levels of eotaxin, RANTES, VCAM-1, and ICAM-1, which subsequently contributed to the inhibition of eosinophil migration. Furthermore, casticin inhibited IκB-α phosphorylation and nuclear translocation of p65 in A549 cells.. Casiticin inhibited the eosinophil migration and activity of chemokines and adhesion molecules involved in the inflammatory process of asthma by suppressing the NF-κB pathway. These results suggest that casticin has the potential for use in the treatment of allergic asthma.
