  • Materials and Methods
  • Fig. S1. PARPi and MEKi induce inverse adaptive responses.
  • Fig. S2. Long-term assay of combination therapy with PARPi and MEKi demonstrates that low doses of drugs show synergy in OVCAR8 cells.
  • Fig. S3. PARPi plus MEKi/ERKi demonstrate synergy in cells with RAS mutations.
  • Fig. S4. Synergistic effects of PARP and MEK/ERK inhibition are lineage-independent and observed with KRAS/NRAS/BRAF mutations.
  • Fig. S5. RAS/ERK pathway activity is associated with HR competence, DNA damage checkpoints, and apoptotic sensitivity.
  • Fig. S6. MEKis decrease HR competence and enhance DNA damage induced by IR or PARPi.
  • Fig. S7. PARP and MRE11, but not FOXM1, contribute to the synergistic effects of PARPi and MEKi.
  • Fig. S8. PARPi, MEKi, and combination therapy have no effect on the body weight of mice.
