Supplementary Figure S1. Chemical structures of selected tankyrase inhibitors. Supplementary Figure S2. OM-153 specifically inhibits TNKS1/2 and WNT/β-catenin signaling. Supplementary Figure S3. OM-153 specifically inhibits cell growth of an APC-mutated colon carcinoma cell line. Supplementary Figure S4. OM-153 shows an anti-proliferative effect in human cancer cell lines. Supplementary Figure S5. OM-153 inhibits WNT/β-catenin, YAP and MYC signaling in human cancer cell lines. Supplementary Figure S6. OM-153 inhibits the WNT/β-catenin signaling pathway and shows anti-tumor effect in a human colon carcinoma xenograft model. Supplementary Figure S7. Combined OM-153 and anti-PD-1 treatment confers anti-tumor effect in mouse melanoma. Supplementary Figure S8. PO-BID treatment with 10 mg/kg OM-153 does not reduce body weight and food consumption or induce toxicity in mice.
