title: [Aberrant Expression Notch1 and Asb2 mRNA in Bone Marrow from Patients with P210(+) Chronic Myeloid Leukemia].
abstract: OBJECTIVE
  To explore the mRNA expression level of Notch1 and ASB2 in bone marrow mononuclear cells of patients with P210(+) chronic myeloid leukemia and the correlation between Notch signaling pathway and ubiquitination in chronic myeloid leukemia, so as to provide the valuable information for investigating the pathogenesis of chronic myeloid leukemia and clinical treatment.
  
  
  METHODS
  Bone marrow was collected from 32 patients with newly diagnosed chronic myeloid leukemia and 34 non-hematopathic and healthy individuals (control group), respectively. The mRNA expression levels of Notch1 and ASB2 were detected by real-time quantitative PCR.
  
  
  RESULTS
  The expression of Notch1 mRNA in CML patients were significantly different from that of healthy individuals group (t=36.3, P<0.01), which was 337.8 times of the healthy individuals. Moreover, the expression level of ASB2 mRNA in CML group was significantly higher than that in healthy individuals (t=19.4, P<0.01). The mRNA expression of Notch1 and ASB2 gene was positive correlation (r=0.504, P<0.01).
  
  
  CONCLUSIONS
  The aberrant expression of Notch1 and Asb2 exists in patients with P210 positive CML, which may be involved in incidence and development of CML.
