a Primary tumour volume in Placebo (P) (day 2: n = 11 tumours (n = 8 mice), day 5: n = 11 tumours (n = 7 mice), day 12: n = 13 tumours (n = 7 mice)), Anakinra (A) (day 2: n = 9 tumours (n = 7 mice), day 5: n = 9 tumours (n = 6 mice), day 12: n = 13 tumours (n = 8 mice), Dox and Zol (DZ) (day 2: n = 8 tumours (n = 6 mice), day 5: n = 15 tumours (n = 8 mice), day 12: n = 15 tumours (n = 8 mice)), Anakinra, Dox, and Zol (ADZ) (day 2: n = 8 tumours (n = 5 mice), day 5: n = 13 tumours (n = 8 mice), day 12: n = 13 tumours (n = 7 mice)). Data are mean +/− SEM, two-way ANOVA with Tukey’s multiple comparisons test (A vs. P *P = 0.01, A vs. DZ **P = 0.002, A vs. ADZ ***P = 0.0001). b, c PCNA+ and Cleaved-Caspase 3+ cells (%) in primary tumours. Each data point represents one or more tissue sections from an individual primary tumour. Data are mean +/− SD. One-way ANOVA with Tukey’s multiple comparisons test (P vs. ADZ *P = 0.04, A vs. ADZ *P = 0.02). Scale bar = 50 µm. d Casp3+ IHC. e, f Metastases (%) and BLI images (P (n = 7 mice), A (n = 8 mice), DZ (n = 8 mice), or ADZ (n = 7 mice)). Fisher’s exact test: *P = 0.02 P vs. ADZ (bone metastases); *P = 0.04 DZ vs. ADZ (lung metastases). g, h Animals with metastases (%) (P (n = 6), A (n = 6), DZ (n = 6), or ADZ (n = 6)) (intra-cardiac injection of E0771 luc2 GFP cells). i, j Animals with metastases (%) P (n = 8), A (n = 8), DZ (n = 8), or ADZ (n = 7) (intra-cardiac injection of 4T1 luc2 cells). km BV/TV % in tibiae from the spontaneous metastasis (k) and overt bone metastasis (L-C57BL/6, M-BALB/c) models.
