EEN RNAi in the hematopoietic cells. Western blot analysis showing RNA interference in 293T cells (A) and HL60 and Kasumi-1 cells (B). (C) The cell proliferation curves and cell-cycle distribution of HL60 cells with FIV-R1 as compared with the control (FIV). Note that the difference in the proliferation between the 2 cell populations becomes significant on day 6 (P = .030). These results were repeated at least 3 times and a representative one is shown. (D) The cell-proliferation curves and cell-cycle distribution of Kasumi-1 with FIV-R1 as compared to the control (FIV). Note the difference in cell proliferation was significant on day 6 (P = .045).
