ABSTRACT
<p><b>OBJECTIVE</b>To study the effect of reactive oxygen species (ROS) during the leukemogenic process associated with exposure to benzene.</p><p><b>METHODS</b>HL-60 was treated with 3 micromol/L benzoquinone (BQ). Generation of ROS in cells was measured by DCFH-DA method. For proliferation assays,cells were stained with alamar blue dye and counted.</p><p><b>RESULTS</b>ROS production and the proliferation of cell were all increased in BQ-treated cells (13.10 +/- 0.15, 185% +/- 30.00%) as compared with control cells (11.32 +/- 0.09, 100% +/- 0.00%) (P < 0.05); The addition of catalase just before BQ addition reduced ROS generation to basal levels and decreased the growth of cell (P < 0.05).</p><p><b>CONCLUSION</b>ROS may play an important role in the process of proliferation of HL-60 cells induced by BQ.</p>
