We could observe a significant inverse correlation between antibody titer values and the tumor volume (r = −0.738; p = 0.048; Figure 5a) as well as the area occupied by CD31+ cells (r = −0.785; p = 0.028; Figure 5b) inside tumor tissues of animals involved in the study, while the same was not observed for the number of Ki67+ cells (Figure 5c). This evidence concerns the gene MKI67 and neoplasm.
