Outline of Final Research Achievements |
The tumor suppressor gene BAP1 is known to be mutated in many cancers, including malignant mesothelioma. When the oncogenic gene is a tumor-suppressor gene, it is generally difficult to develop drugs that activate them. Therefore, we searched for a new molecular target for BAP1 mutation, one of the causative genes of malignant mesothelioma, by focusing on DNA damage response factor using synthetic lethal phenotype. As candidate genes, gene A encoding deubiquitination enzyme and gene B encoding kinase involved in DNA damage repair were obtained. This suggests that these genes are likely to be novel molecular targets for BAP1-mutant cancers.

Academic Significance and Societal Importance of the Research Achievements |
今回の研究成果から、BAP1変異がんをはじめとするがん抑制遺伝子変異が原因遺伝子となるがんにおいて、合成致死表現型を用いることで有力な新規分子標的が得られることが明らかとなった。また、BAP1と今回得られた候補遺伝子の関わりについてはこれまで報告がないため、BAP1とこれらの候補遺伝子が合成致死を示す分子機構を明らかとすることで、新たな制御機構を明らかにすることができると考えられる。
