Mechanisms involved in Korean mistletoe lectin-induced apoptosis of cancer cells

Figure 2 Tumor-killing effect of VCA in vivo. COLO cells (1 × 10⁷ cells/mouse) were injected into the neck of CD1 nude mice. Five weeks later, VCA was injected around the developed tumors every 2 d for 5 wk. (A) The tumors were measured at 0, 1, 3 and 5 wk after VCA treatment and (B) were photographed at the end of experiment. The size of the tumors decreased (a-c) at 5 wk of treatment and eventually disappeared at 2 mo after the termination of VCA treatment (d).
