Introduction. Actinidia chinensis Planch. root extract (acRoots), known as a traditional Chinese medicine (TCM), has shown antitumor efficacy in various types of human cancers. However, its role and underlying mechanisms in breast cancer (BCa) have not been elucidated.

Material and methods. In the present study, the effects of acRoots on cell viability, apoptosis, migration and invasion were analyzed by MTT assay, colony formation, flow cytometry, wound healing and Transwell assay in MDA-MB-231 and MDA-MB-453 breast cancer cell lines. The expression levels of relevant proteins were determined by Western blot assay.

Results. The results revealed that acRoots inhibited proliferation, migration, and invasion and promoted apoptosis of BCa cells. Moreover, acRoots decreased the expression of cyclin D1, survivin, Bcl-2, N-cadherin, and Snail and increased the expression of Bax and E-cadherin in MDA-MB-231 and MDA-MB-453 cells. AcRoots inhibited the AKT/GSK-3b pathway by decreasing the levels of phosphorylated AKT, phosphorylated GSK-3b and b-catenin.

Conclusions. The described effects of acRoots on the cultured BCa cells suggest that they may be mediated by the inhibition of the AKT/GSK-3b signaling pathway. Thus, further studies are warranted to test the possibility that AcRoots may be used as a promising anticancer agent for breast cancer treatment.
