Figure 4.
K562 cell apoptosis upon knockdown of NUDT21.
Notes: (A) The activities of Caspase3/7 were determined by Caspase-Glo 3/7 assays in K562 cells (1.5×104) after transfection of shRNA control or NUDT21 shRNA. (B) The percentage of annexin V-positive revealed apoptosis. Percentages of cells undergoing apoptosis in different groups are shown. (C and D) Bax and Bcl-2 protein were determined by Western blot analysis in K562 cells after transfection of shRNA control or NUDT21 shRNA. Data are expressed as mean ± SD for duplicate experiments. **P<0.01; ***P<0.001.
