RESUMO

OBJECTIVE: To investigate the role of Pim-3 abnomal expression in development of acute myeloid leukemia. METHODS: Semi-quantitative RT-PCR was used to detect the expression of Pim-3 in bone marrow of 47 newly diagnosed and untreated patients with acute myeloid leukemia (AML) and 18 patients with AML after treatment with chemotherapy. At the same time, the bone marrow of 10 cases of non-hematologic malignancies was used as normal control. The difference of the Pim-3 gene expression in bone marrows among the 3 groups was also compared. RESULTS: According to the RT-PCR detection results, the Pim-3 expression level in bone marrow of AML patients before chemotherapy were all significantly lower than those in patients with non-hematologic malignancies (P < 0.01). After chemotherapy, there were no significant differences of the Pim-3 expression level between the patients with acute myeloid leukemia and non-hematologic malignancies (P > 0.05), but the Pim-3 expression level was significantly lower in patients before chemotherapy as compared with that in patients post chemotherapy (P < 0.01). The comparison of Pim-3 expression before and after chemotherapy in remission group showed that Pim-3 expression levels before chemotherapy were all significantly lower than those after chemotherapy (P < 0.01), but there were no significant differences of Pim-3 expression levels between patients before and after chemotherapy in non-remission group (P > 0.05). The Pim-3 expression levels of non-remission patients after chemotherapy were all significantly lower than those of the remission patients after chemotherapy (P < 0.01). CONCLUSION: Pim-3 gene is abnormally expressed in the AML patients before and after chemotherapy, and this gene may be involved in the genesis and development of acute myeloid leukemia.
