| Outline of Final Research Achievements |
I found that overexpression of Fbxl10, a histone demethylase, in hematopoietic stem cells induced leukemia. To elucidate the underlying molecular mechanisms, I isolated Fbxl10-overexpressing hematopoietic stem cell and performed RNA-seq analysis. I found the enhanced expression patterns of neuron specific gene 2 (Nsg2) that is implicated in intracellular transport, and genes involved in oxidative phosphorylation. In addition, by ChIP analysis, I confirmed that these genes are direct targets of Fbxl10. These results provide novel insights into the leukemogenic mechanisms from the viewpoint of intracellular transport and oxidative phosphorylation.
