Figure 3. Immunohistochemical analysis of tumor xenografts of MDA/LUC-shUGT8 cells with silenced expression of UGT8 gene and control MDA/LUC cells.

Figure 3

(A) Immunohistochemical staining with monoclonal antibody against Ki67 antigen of tumor sections after subcutaneous implantation of control MDA/LUC cells (I) and sh-transduced MDA/LUC-shUGT8 cells with decreased expression of UGT8 (II) into nu/nu mice. The numbers of Ki67-positive cells in MDA/LUC (I) and sh-transduced MDA/LUC-shUGT8 tumors were compared by Mann-Whitney U-test (***p<0.0001). (B) TUNEL technique after subcutaneous implantation of MDA-M/LUC cells (I) and MDA/LUC-shUGT8 cells (II) breast cancer cells into nu/nu mice. Original magnification: x100. The numbers of apoptotic cells in MDA/LUC (I) and sh-transduced MDA/LUC-shUGT8 tumors were compared by Mann-Whitney U-test (*p = 0.0432).
