Outline of Final Research Achievements |
We aimed to identify genomic and epigenomic alterations from endometriosis to ovarian cancers. Single-cell sequencing analysis will reveal the genomic and epigenomic abnormalities that accumulate during the transition from endometriosis to ovarian clear cell carcinoma and elucidate the pathogenic mechanism of ovarian clear cell carcinoma. To this end, we sampled normal endometrium, endometriosis, and ovarian clear cell carcinoma, and performed whole-exome sequencing for normal endometrium, endometriosis, atypical endometriosis, and carcinoma. In addition, we isolated single glands from normal endometrium tissue by laser microdissection, and conducted whole genome sequencing for them. We confirmed that we could extract DNA from cells after laser microdissection and perform whole genome sequencing.

Academic Significance and Societal Importance of the Research Achievements |
卵巣明細胞がんは日本で頻度の高い卵巣がんであり、プラチナ併用化学療法に抵抗性を示すことから、発症予防が重要になる。正常子宮内膜から子宮内膜症、明細胞癌に移行するにつれて蓄積されるゲノム異常を同定することができ、今後子宮内膜症や卵巣明細胞癌の発症予防に役立つ情報を得ることができた。
