Anticancer effect of fermented Insampaedok-san in human colon cancer cells: a pilot study.

Insampaedok-san (IPS) is one of the East Asian traditional medicines which have been prescribed for hundreds of years to treat common cold and headache. Although many herbs and prescriptions are known to have significant activities against diseases, only a limited number of reports and scientific evidences on their efficacies are available. To identify anticancer effect against colon cancer, traditional prescription IPS and its fermented IPS (FIPS) were examined by in vitro molecular biological analysis. IPS water extract was fermented, lyophilized, and examined by cytotoxicity, cell cycle, and western blot assays, using cancer cell lines. Resultantly, FIPS showed significant cytotoxicities inducing caspase dependent apoptosis and activation of caspase-3 (CASP3) and poly (ADP-ribose) polymerase (PARP) cleavage in colon cancer cell line SW620. These findings can be useful for development of anticancer functional food or complementary and alternative medicine, with remaining in-depth molecular functional studies.
