Outline of Final Research Achievements |
By genome-wide loss-of-function screening using three prostate cancer cell lines, we obtained gene candidates for synthetic lethal with PARP. Genes related to DNA damage and DNA replication were identified in addition to homologous recombination repair. These genes show synergistic effects when they are simultaneously inhibited by PARP and are promising therapeutic targets.

Academic Significance and Societal Importance of the Research Achievements |
去勢抵抗性前立腺癌に対するPARP阻害療法は有望な治療法であるものの、現時点での治療対象は相同組み換え修復欠損を有する症例に限定されており、奏効期間も限られている。当研究ではPARPと合成致死を示す新たな遺伝子を明らかとした。PARPと同時に阻害することで、これまで無効と考えられた症例にも奏効する可能性があり、新規治療につながるものと考えている。
