Full description or Abstract
Hematopoietic defects in HOXA9(-/-) mice demonstrate a key role
for this homeoprotein in blood cell development. Conversely, enforced
HOXA9 expression is leukemogenic in mice, and HOXA9 is frequently
activated in human acute myeloid leukemia (AML). Although HOXA9
is thought to function as a transcription factor, few downstream
targets have been identified. We searched for early HOXA9 target
genes by using a transient overexpression strategy in 3 hematopoietic
cell lines (2 myeloid, 1 lymphoid). cDNA microarray analyses identified
220 genes whose expression was modulated at least 2-fold. Expression
signatures in myeloid and lymphoid cells demonstrated that HOXA9
functions as both an activator and repressor of a variety of genes
in cell-specific patterns suggesting that the transcriptional
effects of HOXA9 are largely dependent on the cell context. Transient
transcription assays and target gene expression patterns in HOXA9(-/-)
marrow cells imply that we have identified direct physiologic
targets. Many target genes are expressed in CD34+ stem cells or
are members of gene families involved in proliferation or myeloid
differentiation. Expression of 14 HOXA9 target genes correlated
with high-level HOXA9 expression in primary AML. These data suggest
that many genes identified in this survey may mediate the biologic
effects of HOXA9 in normal and leukemic hematopoiesis.
