3H-Thymidine | 41±8.4 | 36±2.07 | 26±2.4 | 39.5±1.5 | 12±0.38 | 32.7±.0.48 |
The level of c-Abl/Arg activities (Fig. 1) and presence of other nilotinib targets were tabulated, and +’s added together to create a “Score”. Outcome of tritiated thymidine incorporation assays using nilotinib (0.5μM) also are shown. An inverse correlation between the number of nilotinib targets and tritiated thymidine incorporation is shown in Figure 2d.
