In order to investigate the mechanism of acute lymphoblastic leukemic cell malignant proliferation, the expressions of hMSH2 mRNA and mutation P53 (mtP53) protein in bone marrow cells of de novo acute lymphoblastic leukemia (ALL) were determined by in situ hybridization and immunocytochemical methods. The results showed the that percentage of positive cell with hMSH2 mRNA expression was (32.88 +/- 11.46)% in the de novo ALL group and (64.22 +/- 8.51)% in the control group. The percentage of positive cell with mtP53 protein expression was (29.25 +/- 9.45)% in the de novo ALL group, and (12.63 +/- 6.66)% in the control group. There was a significant negative correlation between the positive percentages of hMSH2 mRNA expression and mtP53 protein expression (r = -0.45, P < 0.05). It is concluded that defective MSH2 mRNA expression plays an important role in the pathogenesis of acute lymphoblastic leukemia, mtP53 protein mutation plays an important role in the development of acute lymphoblastic leukemia, the hMSH2 mRNA defect can lead to accumulation of the mutant P53 protein in acute lymphoblastic leukemia, and both jointly promote the pathogenesis of ALL.
