Figure 7. LPLI increases intracellular cAMP level to suppress NF-κB transcriptional activity.

Figure 7

(A) Intracellular cAMP levels were measured by ELISA in hADSCs treated with LPS, LPLI, SQ22536, and forskolin. (B) NF-κB transcriptional activity was assayed 5 hours after LPLI treatment only and combined pretreatment of SQ22536. The data are expressed as the mean ± SD (n = 6). The following statistical levels were applied: *p<0.05 and **p<0.01 compared to the control, #p<0.05 compared to LPS (50 ng/ml), and †p<0.05, ††p<0.01, and †††p<0.001 compared to LPLI (8 J/cm2).
