Outline of Final Research Achievements

We established RUNX1-mutated induced pluripotent stem cells (iPSs) derived from familial myelodysplastic syndromes (MDS) pedigrees. Familial MDS-iPSCs were clearly defective in the emergence of hematopoietic progenitors and differentiation of megakaryocytes. The familial MDS-iPSCs are thought to be a useful tool to investigate RUNX1 mutant-mediated molecular mechanisms of MDS, however, blast cells did not expand during long time culture. Therefore, additional gene abnormalities should be required to develop MDS. We investigated gene abnormalities in familial MDS patients with RUNX1-mutations using whole-exome sequencing. As a result, we identified recurrent CDC25C mutations to drive malignant transformation in familial MDS pedigrees.
