Figure 5From: Novaferon, a novel recombinant protein produced by DNA-shuffling of IFN-α, shows antitumor effect in vitro and in vivoThe immuno histochemical analysis result of caspase 3 in each group. Caspase-3 protein increased in dissected tumor tissues after mice was treated by IFN-α2b (B) and Nova (C) compared with the negative control (A). D is quantization of the expression of the proteins evaluated in the different samples with immunohistochemistry.Back to article page
