Abstract:
This study was aimed to quantitatively detect the expression level of beta-catenin and bcr/abl in different phases of chronic myeloid leukemia (CML) and to analyze their potential relationship and significance in the progression of CML. First, the total RNA isolated from BMMNC of patients with CML and donors was reversely transcribed into cDNA. The real-time quantitative PCR method was used to analyze the expression level of beta-catenin and bcr/abl. The expression level of beta-catenin and bcr/abl in different phases of CML was compared and the correlation was analyzed between the two genes. The results showed that the beta-catenin gene in BMMNC of blast crisis of CML patients was expressed significantly higher than that in chronic phase (p < 0.001) and accelerated phase (p = 0.016) of CML patients and in normal donors (p = 0.004). The expression of bcr/abl in blast crisis of CML was statistically higher than that in chronic phase of CML (p = 0.001). The expression levels of beta-catenin and bcr/abl were correlated with each other in CML patients (r = 0.620, p < 0.001). It is concluded that the beta-catenin gene in blast crisis of CML patients express higher than that in chronic phase and accelerated phase of CML, and its expression level is correlated with the level of bcr/abl expression. The increased expression of beta-catenin may be account partly for the blast crisis of CML.
