Abstract
Chrysin is a natural, biologically active compound extracted
from many plants, honey and propolis. It possesses
potent anti-inflammation, anti-cancer and anti-oxidation properties.
The mechanism by which chrysin suppresses COX-2 expression
remains poorly understood. In the present report, we
investigated the effect of chrysin on the expression of COX-2
in lipopolysaccharide (LPS)-activated Raw 264.7 cells. Chrysin
significantly suppressed the LPS-induced COX-2 protein and
mRNA expression in a dose-dependent manner. The ability of
chrysin to suppress the expression of the COX-2 was investigated
using luciferase reporters controlled by various cis-elements
in COX-2 promoter region. Mutational analysis and
electrophoretic mobility shift assay verified that nuclear factor
for IL-6 was identified as responsible for the chrysin-mediated
COX-2 downregulation. These results will provide new insights
into the anti-inflammatory and anti-carcinogenic properties of
chrysin.
