During the process of normal hematopoiesis, proliferation is tightly
linked to maturation. The molecular mechanisms that lead to production
of mature effector cells with a variety of phenotypes and functions
from a single multipotent progenitor are only beginning to be
elucidated. It is important to determine how these maturation events
are regulated at the molecular level, because this will provide
significant insights into the process of normal hematopoiesis as well
as leukemogenesis. Transcription factors containing the highly
conserved homeobox motif show considerable promise as potential regulators of hematopoietic maturation events. In this study, we
focused on identification and characterization of homeobox genes of the
HOX family that are important in regulating normal human myeloid
differentiation induced by the hematopoietic growth factor,
granulocyte-macrophage colony-stimulating factor (GM-CSF). We have
identified three homeobox genes, HOX A5, HOX B6, and HOX B7, which are
expressed during early myelopoiesis. Treating bone marrow cells with
antisense oligodeoxynucleotides to HOX A5 resulted in inhibition of
granulocytic/monocytic hematopoiesis and increased the generation of
erythroid progenitors. Also, overexpression of HOX A5 inhibited
erythroid differentiation of the K562 cell line. Based on these
observations, we propose that HOX A5 functions as an important
regulator of hematopoietic lineage determination and maturation.
