摘要

Homeobox genes code for transcription factors known to be important in hematopoiesis and leukemogenesis. In order to understand the function of a homeobox gene in leukemia, we have used an antisense oligonucleotide technique to inhibit the expression of a homeobox gene, DLX7, which is expressed at high levels in some leukemia cell lines and patients. With careful design and use of the antisense oligonucleotide, we have found that the loss of DLX7 gene expression results in loss of expression of secondary genes, cell cycle arrest and apoptosis. These studies have led to an understanding of DLX7 gene function in leukemia cell growth and the identification of genes regulated by DLX7. These studies also raise the possibility that DLX7 antisense oligonucleotides may be useful in the treatment of patients with DLX7-positive leukemia.
