Outline of Final Research Achievements

A long noncoding RNA, CCDC26, which is reportedly the most common gene whose copy number is altered in pediatric acute myeloid leukemia cells. We identified some transcripts abundant in myeloid leukemia cells within the CCDC26 genetic locus, and the concentration of these transcripts in the nuclei of the cells. Knock down of CCDC26 resulted in the prolonged survival period of the cells in the culture medium without serum. The expression of KIT, a well known oncogene functioning as a receptor tyrosine kinase, was significantly enhanced in the CCDC26-knock down cells, suggesting that this gene controls proliferation of the myeloid leukemia cells through KIT expression. These result might give an impact to the therapy strategy for myeloid leukemia with mutated CCDC26 genes.
