Small molecules inhibit the overexpression of the Wnt/β-catenin pathway in cancer cells to regulate cell proliferation and apoptosis.198 C644-0303, a small-molecule inhibitor, was shown to suppress the Wnt/β-catenin pathway to inhibit cell migration and induce apoptosis in CRC cell lines.199 Obatoclax as a pan-Bcl-2 inhibitor had been shown to obstruct BH3-mediated binding of BH3-only proteins or Bax/Bak to induce apoptosis. The gene discussed is BCL2; the disease is cancer.
