The existence of cancer stem cells (CSCs) is central to the pathogenesis and therapy resistance of colorectal cancer. The aim of this study was to evaluate whether Huaier aqueous extract, a Chinese medicine, has efficacy against CSCs and to investigate the mechanisms of its anticancer effects. It was observed that the Huaier extract significantly inhibited the spheroid formation potential (P<0.05) and decreased the aldehyde dehydrogenase (ALDH)-positive cell population in colorectal primary cancer cells (P<0.05). Western blotting analysis and Wnt/β-catenin reporter assays revealed that the Huaier extract downregulated the Wnt/β-catenin self-renewal pathway. This is the first study to demonstrate that Huaier aqueous extract acts as an effective agent for eradicating colorectal CSCs and identifies the Wnt/β-catenin pathway as its potentialtarget, which may be a new approach for colorectal cancer therapy.
