Overexpression of HOXA/MEIS1/PBX3 homeobox genes is the hallmark of mixed lineage leukemia (MLL)-rearranged acute myeloid leukemia (AML). HOXA9 and MEIS1 are considered to be the most critical targets of MLL fusions and their coexpression rapidly induces AML. MEIS1 and PBX3 are not individually able to transform cells and were therefore hypothesized to function as cofactors of HOXA9. However, i...
Since it is known that a 307 bp fragment of the position specific regulatory element of human HOXA-7 contains two (DR3 and DR5) retinoic acid response elements (RAREs) at its 3' end, we constructed several deletion constructs containing different numbers of RAREs and examined their effects in vitro and in vivo. The 5' deletion constructs, BM112 and OM213, retaining both RAREs, were highly respo...
BACKGROUND Poor endometrial quality is associated with more than a third of embryo implantation failures. Current ultrasonography technology lacks the capacity to determine efficiently the endometrial receptivity during ongoing cycle transfers. We analyzed the relationship between the gene expression profile associated with implantation and clinical pregnancy from endometrial cells taken during...
The intron of the mouse Hoxa-4 gene acts as a strong homeotic response element in Drosophila melanogaster leg imaginal discs. This activity depends on homeodomain binding sites present within a 30 bp conserved element, HB1, in the intron. A similar arrangement of homeodomain binding sites is found in many other potential homeotic target genes. HB1 activity in Drosophila imaginal discs is activa...
Cdx1 is expressed along the embryonic axis from day 7.5 postcoitum until day 12, by which time the anterior limit of expression has regressed from the hindbrain level to the forelimb bud region. To assign a functional role for Cdx1 in murine embryonic development, we have inactivated the gene via homologous recombination. Viable fertile homozygous mutant mice were obtained that show anterior ho...
