Supplementary Figures from A Novel Chemotherapeutic Agent to Treat Tumors with DNA Mismatch Repair Deficiencies
Supplemental Figures contains supplementary figures S1-S13. Supplementary Figure S1. The effect of MSH2 deficiency on cell sensitivity to baicalein. Supplementary Figure S2. Baicalein-treated HEC59 cells are deficient in CHK2-regulated S phase checkpoint arrest. Supplementary Figure S3. Baicalein disrupts the interaction between MutSα and CHK2-ATM. Supplementary Figure S4. Baicalein binds to MutSα. Supplementary Figure S5. Baicalein intercalates DNA but does not form crosslinks. Supplementary Figure S6. XPF deficiency reduces baicalein-induced γ-H2AX and rescues baicalein-induced cell death in HT29 MSH2-deficient cells. Supplementary Figure S7. Baicalein pellets reduce the size of MSH2-deficient xenograft tumors but have little effect on MSH2-proficient tumors. Supplementary Figure S8. Baicalein shrinks MSH2-deficient xenograft tumors in a time-dependent manner. Supplementary Figure S9. Baicalein shrinks xenograft tumors formed by MSH2-deficient LoVo cells. Supplementary Figure S10. Baicalein inhibits the growth of chronic-AOM-DSS-induced colon tumors in Msh2LoxP/LoxPVilCre mice. Supplementary Figure S11. Baicalein inhibits the growth of acute-AOM-DSS-induced colon tumors in Msh2LoxP/LoxPVilCre mice. Supplementary Figure S12. Baicalein have little effect on the growth of chronic-AOM-DSS-induced colon tumors in WT mice. Supplementary Figure S13. Model describing baicalein's mechanism of action.
