Overexpression of KDM4D promotes acute myeloid leukemia cell development by activating MCL-1.

ABSTRACT: Acute myeloid leukemia (AML) is regarded as a fatal cancer in the world. The overall survival in adult patients with AML is still poor. As lysine demethylases, the KDM4 family is found highly expressed in many kinds of tumors. In this study, we demonstrate that KDM4D is overexpressed in AML and knockdown of KDM4D not only inhibits the proliferation of AML cells, but also induces cell cycle arrest and apoptosis. Furthermore, our research shows that KDM4D can regulate the expression of MCL-1 by demethylating H3K9me3 at the promoter region in AML cells. Besides, we find that high expression of KDM4D is correlated with poor overall survival in AML patients. Taken together, our study demonstrated that KDM4D can promote MCL-1 expression in AML and may serve as a novel target for the treatment of AML.
