NUSAP mitotic phosphorylation at Ser 240 correlates with Aurora A activity. Protein samples of FLAG-NUSAP immunoprecipitated from I, M and MtMLN or with MtZM were analysed using LC-MS/MS, focusing on the predicted phosphorylated residue Ser 240. The histograms (A, B) show the calculated ratios based on peptides carrying the phosphorylated Ser 240 compared with all matched peptides containing this residue.

Aurora A inhibition rescues the PPP6C depletion phenotype. (A) HeLa cells transfected for 48 h with control and PPP6C si08 duplexes were treated with 10 or 20 nM MLN8237 or a solvent control for 15 min before lysis in phosphatase inhibitor containing buffer or fixation. Total lysates were analyzed by Western blotting. The red and black lines indicate the hosphorylated and nonphosphorylated forms of Aurora A. Fixed cells were stained using DAPI to detect DNA and antibodies to α-tubulin and Aurora A pT288. The intensity of pT288 staining was integrated using ImageJ over the spindle region defined by TPX2 staining and is plotted in the bar graph ( n = 4). Arrowheads indicate micronuclei. Bar, 5 µm. (B) HeLa cells transfected for 48 h with control and PPP6C si08 duplexes were treated with 10 nM MLN8237 or a solvent control for 24 h before fixation and staining with DAPI to detect DNA.

Eg5 inhibition counteracts the induction of spindle pole fragmentation by Aurora-A inactivation. The protocol to inhibit Aurora-A by MLN8237 in cells progressing towards mitosis is depicted (time intervals not represented to scale). Control cultures were treated with solvent (DMSO) in the same time window. When indicated, MON was added 1 hour before harvesting. Note the absence of active phosphorylated (pThr288) Aurora-A (in red in IF panels) in cells treated with MLN8237. Upper histograms represent the percentage of all spindle and MT abnormalities in control and MLN8237-treated cultures (200 counted PM/M per condition in 2 experiments); the grey fraction of the histograms represents mitoses with spindle extrapoles, while other defects (monopolar or disorganised spindles, few and short MTs) are in white. Lower histograms and IF panels show that concomitant Eg5 inhibition by MON prevents MLN8237-induced spindle pole fragmentation (note the failure of centrosome migration reflecting Eg5 inactivation in lower IF panels). 200 PM/M per condition were counted in 2 experiments. Error bars represent s.d. **: p < 0.001, χ2 test. Red asterisks indicate significant differences with respect to DMSO controls, and black asterisks significant differences between Aurora-Ai mitoses with active or inactive Eg5. Scale bar: 10 μm

Alisertib inhibits AURKA and AURKB in a concentration-dependent manner. (a) Alisertib induces G 2 /M delay or genome reduplication. HeLa cells were exposed to buffer or the indicated concentrations of Alisertib. After 24 h, the cells were harvested and analyzed with flow cytometry. The positions of 2N, 4N and 8N DNA contents are indicated. (b) Alisertib delays mitotic exit or induces slippage. HeLa cells stably expressing histone H2B-GFP were exposed to buffer or the indicated concentrations of Alisertib. Individual cells were then tracked for 24 h with time-lapse microscopy. Each horizontal bar represents one cell (n ¼ 50). Key: light gray ¼ interphase; black ¼ mitosis (from DNA condensation to anaphase or mitotic slippage); dark gray ¼ interphase after mitotic slippage; truncated bars ¼ cell death. (c) Different concentrations of Alisertib are involved in delaying mitotic exit and inducing slippage. Live-cell imaging of cells treated with Alisertib was described in panel (b). The duration of mitosis (mean±90% confidence interval) and the percentage of cells that underwent mitotic slippage during the imaging period was quantified. (d) Alisertib promotes apoptosis in a concentration-dependent manner. HeLa cells were incubated with the indicated concentrations of Alisertib for 48 h. The cells were then harvested and analyzed with flow cytometry. (e) Concentration-dependent cytotoxicity of Alisertib. HeLa cells were cultured in the presence of the indicated concentrations of Alisertib for 48 h. The number of live and dead cells was analyzed with trypan blue exclusion assay. (f) Concentration-dependent suppression of long-term survival by Alisertib. HeLa cells were seeded on 60-mm culture plates and grown in the presence of 250 n M or 1 m M of Alisertib. After 24 h, the cells were washed gently and propagated in normal medium for another 10–12 days. Colonies were fixed and stained with crystal violet solution (examples of the plates are shown). Average±s.d. from three independent experiments. (g) Both AURKA and AURKB are inhibited by Alisertib.Mitotic HeLa cells were obtained by exposure to nocodazole for 16 h followed by mechanical shake off. The cells were incubated with the indicated concentrations of Alisertib for 2 h. Lysates were then prepared and activated phospho-AURKAThr288 and AURKBThr232were detected with immunoblotting. The asterisk indicates the position of an AURKB-like protein (the same throughout this study). Uniform loading was confirmed by immunoblotting for actin. In this assay, nocodazole and MG132 (a proteasome inhibitor) were added to prevent the cells from exiting mitosis. Accordingly, the total AURKA and AURKB levels remained constant throughout the experiment. (h) Alisertib prevents activation of AURKA and AURKB. HeLa cells were incubated with the indicated concentrations of Alisertib for 8 h. Nocodazole was then added for another 6 h to trap cells that entered mitosis. Lysates were prepared and analyzed with immunoblotting. Actin analysis was included to assess loading and transfer.

Inhibition of Aurora A (12.5 nM) by MLN8054 or MLN8237 was assessed in duplicate radiometric assays containing 100 μM [γ-32P] ATP and quantified by p81 phosphocellulose assay and scintillation counting. Kinase activity is reported as a percentage of control calculated from duplicate incubations containing 2.5% (v/v) DMSO. IC50 values represent the mean ±SEM calculated from two independent experiments.

The effects of T217D and T217N Aurora A mutations were directly compared to WT Aurora A-expressing cells. Each well was treated with either DMSO or 500 nM MLN8054 (E), or 30 nM MLN8237 (F) on day one of the experiment and cells were cultured for 8 days, at which point they were fixed. For all colony assays, an area encompassing >90 % of the colonies per dish is shown. Similar results were seen in two independent duplicate experiments.

C, Fry depletion decreases the level of Thr-210 phosphorylation of Plk1 on spindle poles. HeLa cells transfected with siRNAs were cultured in growth medium for 12 h and in thymidine-containing medium for 36 h. They were then released from thymidine arrest for 12 h before being fixed and stained with anti-Plk1 pT210 ( green) and anti-pericentrin (red) antibodies. DNA was stained with TO-PRO-3 ( blue ). For Aurora A inhibition, after release from thymidine block for 10 h, HeLa cells transfected with control siRNA were incubated for2h in medium containing MLN8237 (100 nM) and MG132 (10 μM). Magnified images of the white boxes are also shown. Scale bar ,5 μm.
