In vivo anti-tumour activity of CRAd-S-pk7 in combination with TMZ. (A) Five consecutive injections of TMZ at 70 mg kg−1 per day (▾) achieve 100% survival for 80 days after U87MG implantation, whereas five TMZ injections at 10 mg kg−1 per day (○) had significant increase in survival compared with mock treatment (•) (P<0.05). (B) Single intracranial (i.c.) injection of CRAd-S-pk7 at 5 × 109 vp per mouse (▵) achieves significant increase in survival compared with mice that received two (○) or one (▾) injection of CRAd-S-pk7 at a dose of 3 × 109 vp per mouse or mock control (•) (P<0.05) (C) Five consecutive injections of TMZ at 10 mg kg−1 per day followed by two CRAd-S-pk7 treatments each at 3 × 109 vp per mouse (Δ) showed significant additive effect on mice survival compared with mock (▪) (P<0.02), double injections of CRAd-S-pk7 each at 3 × 109 vp per mouse (▵) (P<0.02) or five consecutive injections of TMZ at 10 mg kg−1 per day (▾) (P<0.02).
