Abstract A15: Downregulation of c-myc is synthetic lethal with PARP inhibitors in high MYC cancers independent of BRCA status

In conclusion, we demonstrated that dual CDK + PARP inhibition is synthetic lethal in both BRCA wild-type and mutant TNBC cell lines and is dependent upon down regulation of c-myc. This study supports c-myc as predictor of response to PARP inhibitor therapy and may also serve as a biomarker of response to Dinaciclib + PARPi therapy in high MYC expressing tumors.Citation Format: Jason PW Carey, Smruthi Vjayaraghavan, Kelly Hunt, Khandan Keyomarsi.
