Abstract:
Objective To investigate the relationship between the expression of DNA methyltransferases(DNMT)and clinical prognosis in children with acute leukemia(AL).Methods The mRNA expressions of DNMT1,DNMT3A,DNMT3B,p15,mdrl were measured in 56 AL children and 20 normal controls by semi-quantitative reverse transcriptionpolymerse chain reaction.Results In 56 cases of children with AL,the positive rate of DNMT1 was 73.2%(41/56);the positive rate of DNMT3A was 67.9%(38 /56);the positive rate of DNMT3B was 64.3%(36/56).Thirty-one cases showed positive expressions of the 3 DNMT simultaneously,4 cases with negative expressionss imultaneously,21 cases with at least 1 positive expression of the DNMT,positive rate of p15 was 19.6%(11/56);positive rate of mdrl was 28.6%(16/56),all 3 simultaneous expressions of the 3 DNMT in AL children were significantly higher than those in normal controls(P
