Effect of OY and fermented OYs on LPS-induced (A) COX-2 and (B) iNOS expression. RAW 264.7 cells pretreated with OY or fermented OYs (500 μg/mL) for 30 min before being incubated with LPS (200 ng/mL) for 24 hours. Equal amounts of protein were used for immunoblot analysis for detection of COX-2 and iNOS. RT-PCR was used for COX-2 and iNOS mRNAs analysis.
