Supplementary Materials

The PDF file includes:

  • Materials and methods
  • Fig. S1. ER cells that have undergone EMT display EGFR independence but have not undergone SCLC transformation.
  • Fig. S2. YAP but not YAP regulators are up-regulated in EGFR TKI–resistant cells that have undergone EMT.
  • Fig. S3. YAP activity is increased in EGFR TKI–resistant cells that have undergone EMT and in drug-tolerant persister cells.
  • Fig. S4. HCC827 ER and HCC4006 ER cells acquired a multidrug-resistant phenotype.
  • Fig. S5. HCC4006 ER cells are sensitive to SAC component inhibitors.
  • Fig. S6. HCC827 ER cells are sensitive to SAC component inhibitors.
  • Fig. S7. Cell line models and patient-derived models of acquired osimertinib resistance are sensitive to inhibition of SAC components.
  • Fig. S8. CDK and SAC component inhibitors induced tumor cell death and increased nuclear size.
  • Fig. S9. FOXM1 regulates SAC component gene expression and promotes osimertinib resistance.
  • Fig. S10. FOXM1 expression correlates with expression of genes encoding SAC components in clinical specimens and is associated with worse overall survival in patients with EGFR-mutant NSCLC.
  • Table S1. Multivariate analysis of FOXM1, DFS, and stage.
  • Legends for data files S1 to S11
