Effects of GALV-GP-R⁻ expression in an immune competent tumor model. a Tumor growth curves of rat 9 L tumors treated with either vehicle (PBS), Virus 19 (expresses mGM-CSF) or Virus 16 (expresses mGM-CSF and GALV-GP R⁻). Virus or vehicle were injected into the right tumor only. b A repeat of the experiment in (A), treating with either vehicle or Virus 16 but with longer follow up until day 60. 5 × 10⁶ pfu of virus in 50 μl was given 5x every other day in each case. Statistical differences between groups were measured by one-way ANOVA at day 31 for a and at day 35 for b. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001
