Figure Lengend Snippet: a Representative bright-field images of Huh7 cells non-treated (NT), treated with romidepsin (Romi), cabozantinib (Cabo), or RomiCabo for 24 h. White arrowheads indicate round cells. Percentage of round cells (normalized over total cell number, n = 3 independent biological experiments; p < 0.0001)). b Immunostaining of Huh7 cells after 24 h of treatment: Actin (cyan), β-Tubulin (magenta), Nuclei (yellow; n = 3 independent biological experiments). White arrows indicate round cells. c, d Immunostaining of monopolar and bipolar spindles with α-Tubulin (green), pS 10 H3 (red), nuclei (blue), ( n = 3 independent biological experiments; p < 0.0001). e Immunostaining of aberrant spindles with NuMa (yellow) and α-Tubulin (magenta; n = 3 independent biological experiments). f Maximal intensity projection (MIP) in XY plan of Huh7 cells treated for 24 h with romidepsin: α-Tubulin (magenta), pS 10 H3 (cyan), nuclei (yellow), reported as representative 3D reconstruction. g pS 10 H3 (S10) and pS 28 H3 (S28) positive cells at 24 h in non-treated (NT), romidepsin (R), cabozantinib (C), RomiCabo (R + C), and PLK1i conditions, normalised over total cell number (DAPI; n = 3 independent biological experiments; p < 0.0001). h Percentage of double-positive pS 10 H3 and pS 28 H3 alive cells after 16 h (left; n = 3 independent biological experiments; p = 0.0017) and 24 h (right; n = 3 independent biological experiments; p = 0.0017) of indicated treatments, measured by flow cytometry. i, j Representative cytometry profiles ( i ) of the DNA content (2n, S, 4n) of alive cells after 24 h, with Propidium Iodide and ( j ) quantification among alive cells ( n = 5 independent biological experiments; p < 0.0001). k Median fluorescence intensity (MFI) of γH2AX among live cells after 24 h by flow cytometry ( n = 6 independent biological experiments; p < 0.0001). l Western blots of reported signalling proteins (quantifications are shown in Figs. – , with the corresponding statistics, n = 3 independent biological experiments). Statistical analysis was performed with one-way ANOVA ( a, g ) or two-way ANOVA ( d ), followed by Tukey multiple comparison ( a, d, g ). Paired two-tailed Friedman followed by Dunn’s multiple comparison ( h, k ). Unpaired two-tailed two-way ANOVA followed by Dunnet’s multiple comparison ( j ). In ( g, i, j ) PLK1i condition was used as positive control of mitotic arrest. Levels of significance: * ,$,# p ≤ 0.05; ** ,$$,## p ≤ 0.01; *** ,$$$,### p ≤ 0.001. Bars represent SEM and notches in dot-plots represent mean levels. *indicates the significance between treated versus non-treated cells; $ is versus romidepsin; # is versus cabozantinib.

Article Snippet: Alb-R26 Met mice carrying liver tumours were treated every two days by oral gavage with cabozantinib (10 mg/kg; TargetMol) and every four days by intraperitoneal injection with romidepsin (1 mg/kg; TargetMol).
