Outline of Final Research Achievements |
Juvenile myelomonocytic leukemia (JMML) is a hematopoietic tumor with poor prognosis that mainly affects children under the age of 5 years. In this study, we performed comprehensive profiling of histone modifications by chromatin immunoprecipitation sequencing (ChIP-Seq) to elucidate the overall molecular pathogenesis mechanism and extracted candidate enhancer regions enriched in the disease-specific histone mark H3K27ac in JMML. In addition, we performed an integrated analysis with other genomic analyses (single-cell RNA sequencing and error-corrected sequencing).

Academic Significance and Societal Importance of the Research Achievements |
若年性骨髄単球性白血病(juvenile myelomonocytic leukemia; JMML)は、主に5歳未満の小児に発症する予後不良な造血器腫瘍である。唯一の根治療法は同種造血細胞移植であるが、満足できる治療成績は得られていない。今回のクロマチン免疫沈降シーケンスを含む網羅的遺伝子解析による研究成果により、JMMLの分子学的発症メカニズムの更なる解明が進み、予後を正確に予測するバイオマーカーに基づく最適医療(PrecisionMedicine)の実現に寄与することが期待される。
