Figure 2. The expression of actin regulatory proteins (Arp 3, Annexin II and c-Src) in TM-4 cells treated with two different concentrations of TiO₂-NPs for 24 h. “3–3”: 30 μg/ml, “3–6”: 60 μg/ml, “3-N”: TM-4 cells were treated with 5 mM NAC for 2 h and then treated with 60 μg/ml 3-nm TiO₂-NPs for 24 h. “24–3”: 30 μg/ml, “24–6”: 60 μg/ml, “24-N”: TM-4 cells were treated with 5 mM NAC for 2 h and then treated with 60 μg/ml of 24-nm TiO₂-NPs for 24 h. n=5, *p<0.05, **p<0.01 compared to the control; ##p<0.01 compared to the NPs.
