Outline of Final Research Achievements

Frequent mutation in RNA splicing factors is a cardinal feature of myelodysplastic syndromes. To understand their molecular mechanisms, we constructed model mice for these alterations in this study. In Sf3b1 hetero knockout mice and Srsf2 mutant conditional knock-in mice the number of hematopoietic stem cells are lower than those in wild type mice, and these repopulation capacities are also reduced. And RNA sequencing of hematopoietic stem/ progenitor cells from Srsf2 mutated mice showed abnormal exon usages in many genes. Thus, in conclusion, these findings suggest that RNA spliceosome mutations lead to deregulated hematopoietic stem cell functions likely due to abnormal RNA splicing.
