Anti-Wnt-1 antibody suppressed tumor xenograft growth in vivo. A). Nude mice bearing Huh7 tumor xenografts were treated with anti-Wnt-1 antibody (dose: 50 μg/kg; once a week), or with PBS as a control (n = 5 in each group). Significant differences in the tumor volumes between anti-Wnt-1 antibody-treated and PBS control groups were observed at the beginning of the third week after initiation of treatment (P < 0.05). B). TUNEL staining of the xenograft specimens removed from controls and mice treated with anti-Wnt-1 antibody (200× magnification). Red arrows indicate the positively stained apoptotic cells. C). Xenograft specimens removed from controls and mice treated with anti-Wnt-1 antibody were immunostained to detect expression of c-Myc, cyclin D1, and survivin (400× magnification). The number of positively stained cells were counted from three randomly selected areas and the values represent mean ± SD (error bars).
