The expression of silence of death domains (SODD) and its clinical significance and relationship with phospho-NF-kappaB-p65 proteins in bone marrow cells of childhood acute lymphoblastic leukaemia (ALL) were explored, and the expression of SODD and phospho-NF-kappaB-p65 in Jurkat cells treated with chemotherapeutic drugs was detected in order to find a new chemotherapeutic target. The expression of SODD and phospho-NF-kappaB-p65 proteins in bone marrow cells was detected by immunohistochemistry in 25 children with ALL. The apoptosis rate was measured by Annexin-V-Fluorescence/PI double-labeling flow cytometry and the expression of SODD and phospho-NF-kappaB-p65 proteins determined by Western blotting in the Jurkat cells. It was found that the expression of SODD and active P65 in ALL was significantly higher than that in normal control group (P<0.05). The expression of the SODD and phospho-NF-kappaB-p65 proteins in the high-risk (HR) group was significantly higher than that in the standard-risk (SR) group (P<0.05). The Pearson rank correlation analysis revealed that there was a positive correlation between SODD and phospho-NF-kappaB-p65 expression (P<0.01, r=0.69). VCR could effectively induce the apoptosis of Jurkat cells, and down-regulate the expression of SODD and phospho-NF-kappaB-p65 proteins in a time-dependent manner, but DNR could not down-regulate the expression of SODD effectively. It was concluded that SODD may be closely related to the clinical classification and prognosis of ALL in children. The expression of SODD and phospho-NF-kappaB-p65 had a definite synergistic relationship with the onset and development of ALL. VCR could down-regulate the expression of SODD and inhibit the NF-kappaB activation, which could recover the sensibility of apoptosis in leukemic cells.
