Effect of KPE on inflammatory mediators. Hs68 cells were pretreated with KPE (1–10 μg/ml) or resveratrol (10 μM) for 24 h. After 2 h of H2O2 exposure, the cells were cultured for additional 24 h. (a) Transcriptional changes in IL-6 and IL-8 were detected via RT-PCR. (b) Protein levels of NF-κB and COX-2 were evaluated via western blotting. GAPDH and α-tubulin were used as the mRNA and protein loading controls, respectively.
