Combination therapy suppressed the proliferation and enhanced ROS generation in leukemic cells. BrdU technique was used to evaluate the suppressive impact of different therapeutic agents on the proliferation of CLL cells (a). ELISA assay was employed to levels of ROS generation in both PBMCs and BMMCs after treatment with various therapeutic groups (b). The correlation between ROS and caspase 9 was evaluated in CLL cells (c)
