This study was purposed to investigate whether the mdr1 participates in antiapoptotic mechanisms of hematologic malignant cells regulated by NF-kappaB and to explore the reversal effect of inhibiting NF-kappaB on drug-resistance of hematologic malignant cells so as to search a novel way for treatment of refractory leukemia. NF-kappaB activity and P-gp expression in K562/A02 cells cultured with PDTC in different concentration or different time were detected by immunohistochemistry and computerized picture analysis. The mdr1 was detected by reverse transcription-polymerase chain reaction, and the relationship among NF-kappaB, P-gp and mdr1 was analyzed. The results showed that in K562/A02 cells the expression of P-gp and mdr1 were positively correlated with NF-kappaB/p65, which showed the concentration and time dependent manner. It is concluded the mechanism of NF-kappaB regulating anti-apoptosis in K562/A02 cells has the correlation with the expression of mdr1 and P-gp. The expression of mdr 1 mRNA and P-gp can be reduced through inhibiting NF-kappaB in K562/A02 cells, so that the sensitivity of chemical therapy can be enhanced on hematologic malignant cells.
