Following a five-dose treatment scheme (Figure 6A), statistically significant differences in tumor growth were observed between mice treated with Mv-HER3-induced PAbs and those treated with PAbs purified from nonimmunized rabbits (239 mm3 ± 65.7 mm3 vs. 568.1 mm3 ± 187 mm3, p < 0.0001) (Figure 6B). This evidence concerns the gene ERBB3 and neoplasm.
