Abstract

This study was aimed to explore the relationship of 6; 9 chromosome translocation with DEK-CAN fusion gene expression in patients with acute myeloid leukemia (AML) and its clinical significance. Chromosome specimens were prepared by routine method after short-term culture of bone marrow cells; karyotype analysis was performed by R banding technique; the expression of fusion gene DEK-CAN was analyzed by RT-nested-PCR in mononuclear cells of bone marrow or peripheral blood of 4 AML patients, for 3 patients received allo-BMT out of 4 patients the dynamic follow-up was performed. The results indicated that t (6; 9) (p23; q34) was confirmed by chromosome karyotype analysis in the four AML patients. The DEK-CAN fusion gene was found during in all four de novo, relapsed and CR patients (100%). And the expression of DEK-CAN fusion gene enhanced apparently in de novo and relapsed patients, and weakened in CR patient. DEK-CAN mRNA was found in the three patients during 1-24 months after allo-BMT. Clinical data showed 2 patients relapsed and died after CR for 1-24 months; the other two patients received allo-BMT got CR and still survive. It is concluded that DEK-CAN fusion gene is the molecular basis in pathogenesis of AML. The detection ...Continue Reading

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
