Telmisartan increases olaparib efficacy in homologous recombination proficient tumors by augmenting type I interferon production

Journal for ImmunoTherapy of Cancer | |

Background <p>Poly-ADP ribose polymerase inhibitors (PARPi) are well-known to treat tumors that are deficient in homologous recombination (HR) DNA repair. However, PARPi can treat breast cancer gene (BRCA) wild-type tumors, the mechanisms behind which are not fully elucidated. We previously reported that tumor-intrinsic programmed death ligand-1 (PD-L1) signals promote HR, and that genetic tumor PD-L1<sup>KO</sup> impairs HR and sensitizes tumors…
