Ethanol Extract of Cordyceps militaris Grown on Germinated Soybeans Attenuates Dextran-Sodium-Sulfate- (DSS-)‎ Induced Colitis by Suppressing the Expression of Matrix Metalloproteinases and Inflammatory Mediators

الملخص EN

The effect of Cordyceps militaris (CM) grown on germinated soybeans (GSC) in the inflammatory bowel disease (IBD) model was studied.

To demonstrate the preventive effect of GSC extract in a dextran-sodium-sulfate- (DSS-) induced acute colitis mouse model, GSC was administered 2 days before DSS coadministration.

GSC significantly suppressed DSS-induced disease activity index (DAI) as well as histopathological scores, compared to control or CM-treated group.

To elucidate the anti-IBD activity of GSC, we checked the level of matrix metalloproteinases (MMPs) and inflammatory mediators.

GSC extract decreased the level of MMP-3 and -9 mRNAs and p53 proteins.

The level and activity of LPS-induced MMP-9 were reduced in GSC-treated RAW264.7 cells.

It also attenuated the level of inducible nitric oxide synthase (iNOS) and tumor necrosis factor- (TNF-) α mRNAs both in colon tissue and in macrophage cells.

These results suggest that GSC can be applied as a protective agent against IBDs.
