As anticipated, miR-939-3p expression was significantly higher in the xenografts of miR-939-3p group, whereas the expression levels of BATF2 mRNA and protein were much lower, compared to the control mice (Figures 6D–G), while immunohistochemical staining of Ki67, a biomarker of cell proliferation, showed that Ki67 expression was much higher in tumor xenografts from miR-939-treated mice than that in control mice (Figure 6H). This evidence concerns the gene BATF2 and neoplasm.
