Effects of 200 μg/ml PM2.5 on NF-κB activity with an activator (LPS) and inhibitor (PDTC). a. Fluorescent cells. b. The effects of LPS and PDTC on NF-κB activity. CHO cells were treated with 200 μg/ml PM2.5. Cells in the PM + PDTC group were treated with 200 μg/ml PM2.5 and 100 μmol/L PDTC. Cells in the LPS group were treated with 100 ng/ml LPS for 2 h and switched to F12-K medium without serum. Cells in the LPS + PDTC group were treated with 100 ng/ml LPS for 2 h and changed to medium containing 100 μmol/L PDTC. An IN Cell Analyzer 1000 system was used to obtain and analyze images of cells every half an hour. The negative control is the same control used in Fig. 3 with the same curve data. The data are expressed as the mean ± SD. Each data point represents an average of three samples
