a–c Histograms representing a Cdc42, b Rac and c RhoA activity levels for MSC and Beas2B cells exposed to Au or SiO2 NPs at 150 µg/ml for 24 h (subcytotoxic conditions). The data are expressed as mean ± SD (n = 3) relative to the level for untreated control cells (100%) and are given for 0, 2, 4 and 6 days post NP exposure. The degree of statistical significance is indicated when relevant (*p < 0.05; **p < 0.01)
