Calycosin Alleviates Injury in Airway Epithelial Cells Caused by PM 2.5 Exposure via Activation of AMPK Signalling

Figure 2

Calycosin inhibits PM 2.5-induced inflammation in B2B cells. (a) Relative levels of IL-6 and IL-8 mRNA transcripts. The P value between 0 um group and 50  μm group for “^∗” is 0.0216 < 0.05; the P value between 0  μm group and 100  μm group for “^∗∗” is 0.0084 < 0.01 in IL-6. The P value between 0  μm group and 50  μm group for “^∗” is 0.0328 < 0.05; the P value between 0  μm group and 100  μm group for “^∗” is 0.0106 < 0.05 in IL-8. (b) Levels of IL-6 and IL-8 in the supernatants of cultured cells. The P value between 0  μm group and 50  μm group for “^∗” is 0.033 < 0.05; the P value between 0  μm group and 100  μm group for “^∗∗” is 0.0035 < 0.01 in IL-6. The P value between 0  μm group and 50  μm group for “^∗∗” is 0.0099 < 0.01; the P value between 0  μm group and 100  μm group for “^∗∗” is 0.0030 < 0.01 in IL-8.
