Outline of Final Research Achievements

Clear cell sarcoma of the kidney is a pediatric renal tumor and characterized by an intragenic duplication mutation of BCOR. The intragenic duplicated sequence of this gene showed no definite transformation ability in multiple cell lines, and transformation with this gene is likely to be dependent on the cellular context. However its overexpression in 293 cells changed gene expression, including several epigenetics related genes, and it was suggested that this gene might be involved in tumorigenesis.

Academic Significance and Societal Importance of the Research Achievements

BCOR遺伝子内重複変異による腫瘍発生の機序は今までほとんど明らかにされていない。発生機序の解析の積み重ねにより、診断法・治療法開発や、BCORの機能の解明につながることが期待される。
