The OPE derived from Xinhui source produced a dosedependent
inhibition towards both iNOS and COX-2 protein and
mRNA expression in Raw 264.7 cells (Fig. 3), hence explaining that
the underlying mechanism of Xinhui OPE inhibition of proinflammatory
mediators, iNOS and COX-2 occurred at both the
transcriptional and post-transcriptional levels.
