Orostachys japonicus (OJ) is a medicinal herb with immunoregulatory, anti-aging, anti-oxidative, and many other therapeutic properties. The purpose of this study was to elucidate the anti-cancer property of cultivated OJ. SW480 cell viability was significantly reduced by cumulative exposure to OJ extract. We also observed inhibitory effects of OJ after 72 hr through the growth and migration of SW480 cells using scratch assay. SW480 cells in OJ-free medium began to move into the scratch site at 24 hr; however, cells in medium containing OJ did not migrate into the scratch site until 48 hr. Male C57BL/6 mice (4 weeks old) were orally administered OJ extract for 31 days before injection of SW480 cells. At 7, 14, and 28 days after subcutaneous injection of SW480 cells, tumor weight and volume were analyzed. The body weight of the OJ-treated group was continuously increased during administration of the OJ extract relative to the control group. Injection of SW480 cells caused a reduction in body weight in all groups; however, the OJ-treated group exhibited a significant increase in body weight after 14 days. Tumor weight and volume were lower in the OJ-treated group than in the control group after 28 days. Although these results suggest that OJ suppresses the proliferation and migration of human colon cancer cells, additional studies are required to provide preclinical evidence before launching clinical trials evaluating OJ as an anti-cancer biohealth product.
