Figure 5.

Analysis of the level and localization of the Chromosomal Passenger Complex (CPC) in early mitosis in MST-312-treated HT1080 cells. A-D, Cells were stained with antibodies against Survivin (in red) and Borealin (in green). Localization of Survivin/Borealin in (A-B) control cells (DMSO) and (C-D) MST-312-treated cells in early mitosis. Red arrows point to examples where the proteins are dispersed along chromatin in treated cells. E-H, Cells were stained with antibodies against Aurora B (in red) and INCENP (in green). Localization of Aurora B and INCENP in (E-F) control cells (DMSO) and (G-H) MST-312-treated cells in early mitosis. In drug-treated cells the levels of all four CPC components are lower and the proteins appears to be dispersed along chromosome arms (red/yellow arrows).
