Effects of TIEG2-knockdown on ethanol-induced MAO B mRNA level, generation of H2O2, and cell proliferation rate (MTT assay). GAPDH-overexpressed U-118 MG cells were transfected with TIEG2-siRNA or control-siRNA. a After transfected with siRNA for 3 days, TIEG2 protein from each cell line was evaluated by Western blot analysis. b After transfected with siRNA for 24 h, cells were treated with 75 mM ethanol, and then harvested after 2 days for determining MAO B mRNA level, c the production of H2O2 and d cell proliferation rate/viability. Controls were untreated cells (ethanol 0 mM) which were taken as 1 in (b) or taken as 100% in (c) and (d). Data represent the mean ± SD of three independent experiments.
