Expression of Maf-b mRNA in de novo leukemia patients and its clinical significance / 中国实验血液学杂志

ABSTRACT

This study was aimed to quantitatively detect the level of maf-b mRNA in leukemia patients and evaluate its clinical significance. Real-time fluorescence quantitative PCR was used to detect the relative expression level of maf-b mRNA. The expression change of maf-b mRNA in various types of leukemia was analyzed. Then, the relationship of maf-b mRNA expression with laboratory index and the response to chemotherapy was analyzed. The results showed that maf-b mRNA expression level in acute myeloid leukemia (AML) patients was lower than that in normal group (p<0.01) and positively correlated with white blood cell count (p<0.01) and the expression of CD34 (p<0.01). There was no correlation between maf-b mRNA expression level and chemotherapy response in AML patients except for acute promyelocytic leukemia (APL). Maf-b mRNA expression levels in acute lymphoid leukemia (ALL) and chronic myeloid leukemia (CML) patients were also lower than that in normal group (p<0.01). It is concluded that there is low expression of maf-b gene in AML patients. Abnormal expression of maf-b correlates with abnormal proliferation of AML cells, which may be a new prognostic factor for AML.
