Supplementary Figures S1-10 from Tumor Suppressor HIPK2 Regulates Malignant Growth Via Phosphorylation of Notch1

Supplementary Figure 1: ADR suppresses Notch1 signaling. Supplementary Figure 2: ADR inhibits the transcriptional activity of Notch1 by inducing HIPK2. Supplementary Figure 3: HIPK2 regulates the Notch1-IC protein stability through proteasomal degradation pathways. Supplementary Figure 4: HIPK2 facilitates Notch1-IC degradation by Fbw7 ubiquitin ligase. Supplementary Figure 5: HIPK2 physically interacts with Notch1-IC. Supplementary Figure 6: HIPK2 phosphorylates Notch1-IC at the T2512 residue. Supplementary Figure 7: HIPK2-mediated downregulation of Notch1-IC suppresses the tumorigenesis of breast cancer. Supplementary Figure 8: Somatic mutations in the CPD motif of Notch1-IC make it resistant to HIPK2. Supplementary Figure 9: Physiological effects of somatic mutations in the CPD motif of Notch1-IC. Supplementary Figure 10: A propose model of Notch1 signaling pathway regulation by HIPK2 in cancer during chemotherapy.
