Effects of nanoparticles on cytotoxic activity and AXL suppression in lung cell lines. (A). IMR90, BEAS-2B, H1975 and H1299 cells were incubated with free quercetin (Qur), NP-Q or CM-NP-Q for 48 h, and cell viability was determined by MTT assay. (B). The cells were treated with nanoparticles for 24 h, and the AXL expression level was detected by Western blot. β-actin served as the loading control and the relative expression levels of AXL were quantified. The data shown here are the means of three independent experiments ± SD. **p < 0.01 and ***p < 0.001
