CPC activity spreads from centromeres to chromosome arms after nuclear envelope breakdown. (A) Assay scheme. (B) Cells that have endogenous survivin replaced with the survivinH80A mutant are unable to phosphorylate histone H3Ser10 in the ZM washout assay. HeLa cells stably expressing vector only, survivin-myc (siRNA resistant [res]), and survivinH80A-myc (siRNA resistant) were treated with survivin siRNA for 48 h followed by 1 h in ZM, MG132, and monastrol. Bar, 2.7 µm. (C) Mean total phospho–histone H3Ser10 intensity at 0 and 15 min in mock-treated (vector [vec.] only) and survivin siRNA-treated vector only (vector only + siRNA) and survivin-myc (wild type [WT] resistant)– and survivinH80A-myc (H80A resistant)–expressing cells. Error bars show standard deviations. a.u., arbitrary units. (D) Western blot showing Aurora B, survivin-myc, and endogenous survivin levels. Molecular mass markers are given in kilodaltons.
