Compiling data from groups of animals mock and HV-68 infected mice with metastatic breast cancer demonstrated no significant differences in splenomegaly (Figure 6A), total splenocytes (Figure 6B), the percentage of CD11b+splenocytes (Figure 6C), or the percentage of CD11b+Gr-1+ bone marrow cells or splenocytes (Figure 6D). This evidence concerns the gene ITGAM and breast cancer.
