Outline of Final Research Achievements

The purpose of this study is to clarify the efficacy of poly (ADP-ribose) polymerase (PARP) inhibitor in esophageal cancer chemotherapy. This study indicated that PARP inhibitors such as olaparib synergistically potentiates the sensitivity to anticancer drugs, especially DNA-damaging agents, in human esophageal cancer cell lines. In addition, the potentiation of sensitivity to anticancer drugs by olaparib was involved in cell signals related to p53-binding protein (53BP1).

Academic Significance and Societal Importance of the Research Achievements

本研究成果から、食道癌化学療法においてオラパリブのようなPARP阻害剤が有用であること、また特に癌細胞のDNAを損傷させる抗癌剤と併用することで相乗的な抗腫瘍効果を得ることができる可能性が示唆された。本研究成果が、食道癌化学療法において薬剤選択の幅を広げるための一助となることが期待される。また、この成果により食道癌のみならず他の癌種への検討に繋がる学術的な波及効果も期待できると考えられる。
