摘要

Antroquinonol (ANQ) is a ubiquinone derivative from the unique mushroom Antrodia camphorata, which exhibits broad-spectrum bioactivities. The effects of ANQ on cancer stem cell-like properties in colon cancer, however, remain unclear. In this study, we found that ANQ inhibited growth of colon cancer cells. The 50% growth inhibitions (GI50) of ANQ on HCT15 and LoVo were 34.8 ± 0.07 and 17.9 ± 0.07 μM. Moreover, ANQ exhibited inhibitory activities toward migration/ invasion and tumorsphere formation of colon cancer cells. Mechanistically, ANQ inhibited pluripotent and cancer stem cellrelated genes and down-regulated β-catenin/T-cell factor (TCF) signaling. Moreover, activation of the phosphatidylinositol-3- kinase (PI3K)/AKT/β-catenin signaling axis was identified to be crucial for regulating the expressions of pluripotent genes, whereas suppression of PI3K/AKT by ANQ inhibited expressions of β-catenin and downstream targets. Molecular docking identified the potential interaction of ANQ with PI3K. Our data show for the first time that the bioactive component of A. camphorata, ANQ, suppresses stem cell-like properties via targeting PI3K/AKT/β-catenin signaling. ANQ could be a promising cancer prevention agent for colon cancer.
