A549 cells in the presence of serum. Cells were pretreated with various
inhibitors, Genistein, Filipin and Chlorpromazine, for 30 min, followed
by 2h exposure to SiO2 NP. Given are means ± SEM of 2 independent
experiments, each with 3 replicates. The normalized fluorescence (%
uptake) were calculated by dividing the SiO2 NP fluoresence in the presence
of inhibitor by the fluorescence of controls without inhibitors.
