A Novel Small-molecule WNT Inhibitor, IC-2, Has the Potential to Suppress Liver Cancer Stem Cells.

Background/aim: The presence of cancer stem cells (CSCs) contributes to metastasis, recurrence, and resistance to chemo/radiotherapy in hepatocellular carcinoma (HCC). The WNT signaling pathway is reportedly linked to the maintenance of stemness of CSCs. In the present study, in order to eliminate liver CSCs and improve the prognosis of patients with HCC, we explored whether small-molecule compounds targeting WNT signaling pathway suppress liver CSCs.
