Outline of Final Research Achievements |
Regarding the enhancer regulation for the Bmp7 expression in kidneys, this study shows that i) the downstream region of Bmp7 does not contain enhancers that are critical for the normal kidney development; ii) the Bmp7 expression in the adult kidney is limited to only small population of cells; iii) the CTCF binding sites at the locus for sure critically impinge on the enhancer regulation; iv) however, the role for the CTCF binding sites specifically in the kidney cannot be ensured unless the precise position of the enhancer is identified and the epigenetic states around the region are revealed.

Academic Significance and Societal Importance of the Research Achievements |
Bmp7の制御という観点からは、より理解を深めていくために、シングルセルレベルでの詳細な解析が必要になってくることを示唆した。エンハンサー制御に関連して得たCTCFの機能およびその調節動態についての知見は、他の遺伝子座においても同様であるはずで、腎臓のみならず広く生体機能をゲノムから探る上での大きな指針となる研究になったと考えている。
