title: [april mRNA expression in newly diagnosed leukemia patients].
abstract: This study was aimed to quantitatively detect the levels of april mRNA expression in leukemia patients so as to provide theoretical basis for the target therapy directing at april in leukemia. Real time fluorescent quantitative PCR was used to detect the relative expression level of april mRNA in newly diagnosed leukemia patients and to analyze the changes of its expression level in various type of leukemia. The results showed that the april mRNA expression level in acute leukemia (AL) patients was significantly higher than that in normal controls, there was statistical difference between them (p < 0.05); april mRNA expression level in acute myeloid leukemia (AML) patients was significantly higher than that in normal controls (p < 0.05) and positively correlated with white blood cell count ≥ 20.0 × 10(9)/L (p < 0.05), but not related with extramedullary infiltration and the expression of CD34. Except for acute promyelocytic leukemia (APL), april mRNA expression level was negatively correlated with sensitivity of patients to chemotherapy. april mRNA expression levels in acute lymphoid leukemia (ALL) and chronic myeloid leukemia (CML) patients were not higher than that in normal controls, there was no statistical difference between them (p > 0.05). It is concluded that april gene overexpression exits in AML patients. APRIL protein produced by AML cells probably plays an important role in abnormal proliferation and drug-resistance of AML cells.
