Fig. 7From: Comparison between micro- and nanosized copper oxide and water soluble copper chloride: interrelationship between intracellular copper concentrations, oxidative stress and DNA damage response in human lung cellsImpact of CuO NP, CuO MP and CuCl2 on the intracellular GSH level. BEAS-2B cells were treated for 2 h (a) or 24 h (b), respectively, with the different copper compounds. Shown are mean values of four determinations derived from two independent experiments ± SD. Statistically significant different from control: *p ≤ 0.05, **p ≤ 0.01 (ANOVA-Dunnett’s T test). 20 μg/mL CuO are equal to 252 μM Cu2+ Back to article page
