Tubeimoside-1 inhibits the growth and invasion of colorectal cancer cells through the Wnt/β-catenin signaling pathway.

Tubeimoside-1 (TBMS1) is considered to have anti-tumor properties. However, the role of TBMS1 on human colorectal cancer (CRC) is still unclear. Therefore, in this study, we investigated the role of TBMS1 on human CRC and explored the underlying mechanism. The cell proliferation of CRC cells was detected by MTT assay. Cell migration and invasion were assessed by Boyden chamber assay, and the involvement of molecular mechanisms was examined by western blot. In this study, we found that TBMS1 inhibited the proliferation, migration/invasion of CRC cells, and it reduced β-catenin expression in CRC cells. Furthermore, overexpression of β-catenin rescued TBMS1-induced proliferation and invasion inhibition, and knockdown of β-catenin potentiated TBMS1-induced proliferation and invasion inhibition. Taken together, our results demonstrate that TBMS1 inhibited CRC cell proliferation and invasion via suppressing the Wnt/β-catenin signaling pathway. Therefore, TBMS1 may represent a chemopreventive and/or therapeutic agent in the prevention of CRC.
