Transcription profiling of human acute myeloid leukemia patients

ABSTRACT: AML/MDS patients carrying 11q amplifications involving the mixed lineage leukemia gene (MLL) locus are characterized by a later onset, a complex aberrant karyotype (CAK) frequently including deletions within 5q, 17p and 7q, as well as fast progression of the disease with extremely poor prognosis. We and other have shown that the MLL gene is over expressed in amplified cases, however, in most of the cases the amplified region is not restricted to the MLL locus. In the present study we investigated 19 patients with AML/MDS and MLL gain/amplification [15 AML (two secondary, following MDS and PV, and three therapy related) and 4 MDS cases (two therapy related)]. By means of array CGH performed in 12 patients (GSE9928) we were able to delineate the minimal deleted regions within 5q, 17p and 7q
