In vitro study | Galangin (Norizalpinin)inhibits the catabolic breakdown of DMBA, as measured by thin-layer chromatography, in a dose-dependent manner.Galanginalso inhibits the formation of DMBA-DNA adducts, and prevents DMBA-induced inhibition of cell growth.Galangincauses a potent, dose-dependent inhibition ofCYP1A1activity, as measured by ethoxyresorufin-O-deethylaseactivity, in intact cells and in microsomes isolated from DMBA-treated cells. Analysis of the inhibition kinetics by double-reciprocal plot demonstrates thatgalangininhibits CYP1A1activityin a noncompetitive manner.Galangincauses an increase in the level ofCYP1A1mRNA, indicating that it may be anagonistof thearylhydrocarbonreceptor, but it inhibits the induction ofCYP1A1mRNA by DMBA or by 2,3,5,7-tetrachlorodibenzo-p-dioxin (TCDD).Galanginalso inhibits the DMBA- or TCDD-induced transcription of a reporter vector containing theCYP1A1promoter. Galangin treatment inhibits cell proliferation and induced autophagy (130 μM) and apoptosis (370 μM). In particular, galangin treatment in HepG2 cells causes (1) an accumulation of autophagosomes, (2) elevated levels of microtubule-associated protein light chain 3, and (3) an increased percentage of cells with vacuoles. p53 expression is also increased. The galangin-induced autophagy is attenuated by the inhibition of p53 in HepG2 cells, and overexpression of p53 in Hep3B cells restored the galangin-induced higher percentage of cells with vacuoles to normal level. |
