High-dose cytarabine, idarubicin, and granulocyte colony-stimulating factor remission induction therapy for previously untreated de novo and secondary adult acute myeloid leukemia.
In human acute myeloid leukemia (AML), point mutations at codon 301 of the c-fms gene have been observed implying an important role in the transformation process.
In two multidrug resistant (MDR) sublines of the HL-60 human acute myeloid leukemia (AML) cell line which overexpress MRP but not P-glycoprotein, the assay detects elevated levels of MRP mRNA (4- to 8-fold) relative to the drug-sensitive parental cells (designated HL-60/W).

When compared with previously published cases, the occurrence of tetraploidy or near-tetraploidy in adult AML, unlike childhood ALL, does not appear to define a distinct subgroup in terms of FAB classification or to carry prognostic implications.
Thus we have found little evidence of over-expression of c-kit in adult AML. mRNA for the c-kit ligand, Steel Factor (SLF) was also quantitated by RPA in these specimens.
Thirty-one patients (27 with acute myeloid leukemia [AML], 2 with acute lymphocytic leukemia [ALL], and 2 with acute mixed lineage leukemia [AMLL]) treated with conventional chemotherapy (CHT) and 23 patients (13 AML, 5 ALL, and 5 with chronic myeloid leukemia [CML]) treated with allogeneic bone marrow transplantation (BMT) were monitored for WT1 expression levels in BM and peripheral blood (PB) by reverse transcriptase-polymerase chain reaction over a long-term period (mean, 29 months for CHT and 24 months for BMT).
This study confirms the high frequency of 11q23 chromosomal breakpoint/MLL rearrangement in adult AML and the probable existence of two different entities with different clinical features according to the presence of a balanced or unbalanced cytogenetic abnormality, the latter being not associated with MLL rearrangement.
Here, we show that TPO, interleukin-3 (IL-3) and, at least in short-term assays, also interferon gamma (IFN gamma) induced proliferation in acute myeloid leukemia (AML-M7)-derived M-07e cells.

The best characterized resistance mechanism in adult acute myeloid leukemia (AML) is the one mediated by the MDR1 gene which has been shown to be associated with poor outcome.
