1 PARP inhibitor resistance and TP53 mutations in patients treated with olaparib for BRCA-mutated cancer: Four case reports. olaparib tumor protein p53 Homo sapiens
2 Exome analyses following olaparib treatment identified de novo TP53 mutations, as well as increased frequencies of pre-existing TP53 mutations compared with the primary tumor. olaparib tumor protein p53 Homo sapiens
3 Exome analyses following olaparib treatment identified de novo TP53 mutations, as well as increased frequencies of pre-existing TP53 mutations compared with the primary tumor. olaparib tumor protein p53 Homo sapiens
4 In HCT116 TP53-/- cells carrying BRCA2 pathogenic mutations, TP53 inactivating mutations were associated with lower sensitivity to olaparib in vitro. olaparib tumor protein p53 Homo sapiens
5 Thus, inactivating TP53 mutations may be associated to olaparib resistance in the presence of BRCA mutations. olaparib tumor protein p53 Homo sapiens
