Research Abstract

We generated transgenic mice that overexpress Fbxl10, a histone demethylase, in hematopoietic stem cells (HSCs), and found that the mice develop leukemia at about 1 year after birth. By bone marrow transplantation, we demonstrated that the leukemia was caused by enhanced HSC-intrinsic proliferative potentials. In addition, we found that neuron specific gene 2 (Nsg2), which encodes a protein involved in intracellular transport, was overexpressed and that genes involved in oxidative phosphorylation in mitochondria were significantly up-regulated. Our findings provide novel insights in the leukemogenic mechanisms from the viewpoint of energy metabolism and intracellular transport.
