Abstract:

<P>Background: Carvacrol is a monoterpenic phenol extracted from traditional Chinese herbs, including oregano and thyme. Currently, carvacrol has been widely studied for its therapeutic role in central nervous system diseases, liver diseases and digestive system cancer. <P> Objective: However, the role of carvacrol in osteosarcoma and its underlying molecular mechanism remain elusive. Here, we aimed to examine the anticancer effects of carvacrol on osteosarcoma. <P> Methods: The effects of carvacrol on the osteosarcoma proliferation capacity were revealed by CCK-8 and colony formation assays. Flow cytometry and Hoechst assays were used to determine the effects of carvacrol on osteosarcoma cell apoptosis. The effect of carvacrol on migration and invasion of osteosarcoma cells was determined by wound healing and transwell tests. Protein expression was evaluated by WB assays. The suppressive effects of carvacrol on osteosarcoma in vivo were examined by a xenograft animal model, immunohistochemistry and HE staining. <P> Results: We demonstrated that carvacrol treatment reduced viability and inhibited the colony formation of U2OS and 143B cells in a concentration-dependent manner. Apoptotic cell number increased after exposure to carvacrol. Meanwhile, the expression of Bax increased, and that of Bcl-2 decreased by carvacrol treatment. In addition, the MMP-9 expression and migration and invasion of 143B and U2OS cells were inhibited by carvacrol. We also found that these carvacrol-induced effects on osteosarcoma are associated with the regulation of the Wnt/&#946;-catenin signaling pathway. <P> Conclusion: Our findings suggest that carvacrol suppresses proliferation, migration, invasion and promotes apoptosis in osteosarcoma cells, in part by regulating the Wnt/&#946;-catenin signaling pathway.</P>
