Lobetyolin is derived from Codonopsis pilosula and has antioxidative effect. MUC5AC gene expression induced by phorbol 12-myristate 13-acetate (PMA) from NCI-H292 cells is inhibited by pretreatment with Lobetyolin, lobetyol or methyl linoleate. Lobetyolin does not affect PMA-induced MUC5AC production from NCI-H292 cells. The amounts of mucin in the cells of Lobetyolin-treated cultures are 100±25%, 487±33%, 524±38%, 411±24%, and 402±45% for control, 10 ng/mL of PMA alone, PMA plus Lobetyolin 1 μM, PMA plus Lobetyolin 10 μM, and PMA plus Lobetyolin 100 μM, respectively[1].

Cell Assay |
After 24 hours of serum deprivation, cells are pretreated with Lobetyolin, lobetyol or methyl linoleate (1, 10, and 100 µM), for 30 minutes and then treated with phorbol 12-myristate 13-acetate (PMA; 10 ng/mL) for 24 hours in serum-free RPMI 1640. After 24 hours, the spent media are collected to measure the secretion of MUC5AC protein and cells are lysed with buffer solution containing 20 mM Tris, 0.5% NP-40, 250 mM NaCl, 3 mM EDTA, 3 mM EGTA, and protease inhibitor cocktail and collected to measure the production of MUC5AC protein (in 24-well culture plate)[1].
