Research Abstract

We performed the functional analysis of AML1dC, which is a dominant negative mutant of AML1. As a result, we found that AML1dC enhances proliferating ability of hematopoietic stem/progenitor cells (HSPC ) and attenuates DNA repair ability of HSPC. Through these mechanisms, AML1dC promotes the development of myelodysplastic syndromes (MDS) and the transition from MDS to acute myeloid leukemia.
