Danthron but not anthrarufin suppresses HO-1-induced cancer cell proliferation. a The growth rates of mock and HO-1-overexpressing HeLa cells cultured in the absence or presence of 10 μM indicated compounds were assessed. Data shown are the mean ± SE of three independent experiments. b The numbers of mock and HO-1-overexpressing cells cultured in the absence or presence of indicated concentrations of danthron or anthrarufin for 9 days were determined. Data shown are the mean ± SE of three independent experiments
