Effect of Rosa laevigata on PM10-Induced Inflammatory Response of Human Lung Epithelial Cells

Figure 3

Inhibitory effects of RL on COX-2 protein expression in PM10-treated A549 cells. RL (125 and 250 μg/mL) was pretreated 1 h prior to PM10-induced inflammation in cells and incubated for 24 h with PM10 (100 μg/mL). Ratio of each protein was measured by ImageJ. Statistical significance was analyzed by unpaired t-test (one-tailed). Values are means ± SEM. compared to the control group. compared to only PM10-treated group.
