Abstract:
Objective To explore the meaning of midkine (MK) levels in serum in different development stage of acute leukemia,and to explore the relationship between MK and WT1.Methods The levels of the MK in serum of 86 cases of acute leukemia and 30 cases of normal people were detected by ELISA.Real-time quantitative PCR (RQ-PCR) method was used to determine the expression of WT1 at mRNA level in 15 AML patients.Results The MK level in serum in the new diagnosed group was higher than that in the complete remission group and the normal control group [7.52 (5.44,10.55) ng/ml vs 3.52 (1.56,5.20) ng/ml vs 2.44 (1.89,3.12) ng/ml].There' s no statistical difference between midkine level in new diagnosed acute B cell leukemia (B-ALL) group and acute myeloid leukemia (AML) group [7.88 (5.78,15.78) ng/ml vs 6.25 (4.59,16.33) ng/ml].The clear correlation was found between the level of serum MK and quantities of marrow WT1 gene (r =0.529,P =0.043).Conclusions The level of MK in serum of acute leukemia patients is increased at the time of new diagnosis and decreased at complete remission.ELISA may be a way to measure the status of AL.The location of MK gene is adjacent to WT1 gene and MK' s clinical significance is similar to WT1' s,furthermore,there is a clear correlation between MK in serum and WT1 of marrow in quantities.
