Abstract:
This study was purposed to analyze the expression level of preferentially expressed antigen of melanoma (prame) transcript in the patients with chronic myeloid leukemia (CML) and explore its clinical significance. Real-time quantitative PCR (RQ-PCR) assay was used to detect the level of prame gene transcript in the bone marrow samples from 30 patients with CML and 15 patients with iron deficiency anemia (IDA). The results showed that CML patients had significantly higher prame mRNA level (0% - 772.25%, median 8.28%) than IDA cases (0% - 1.46%, median 0.19%) (p < 0.001). The level of prame gene transcript was significantly correlated with that of bcr-abl fusion gene transcript (r = 0.708, p < 0.001) in CML patients. Furthermore, 6 patients in blastic crisis (BC) and accelerated phase (AP) had significantly higher prame gene transcript than that of 24 cases in chronic phase (CP) (p = 0.007). In 2 CML patients with sequential samples, prame gene transcript increased in AP and BC, compared with in CP, and was consistent with the altering tendency of bcr-abl transcript. It is concluded that the level of prame gene transcript increases in CML which associates with the progression of the disease, prame gene transcript level can be used for monitoring the disease state.
