Saponin Facilitates Anti-Robo1 Immunotoxin Cytotoxic Effects on Maxillary Sinus Squamous Cell Carcinoma

Figure 2

Effect of IT-Robo1 saponin treatment on xenograft on mice. HSQ-89 cells were inoculated subcutaneously on nude mice. (a) Tumor growth was treated with (1) IT-Robo1 + saponin, (2) IT-Robo1 only, (3) saponin only, and (4) PBS (control): The tumor growth in the mice treated with IT-Robo1 + saponin was inhibited compared to the other mice treated (ANOVA, ). (b) The body weight reduction in the IT- Robo1 + saponin was significantly ameliorated compared to the mice receiving the other treatments (ANOVA, ). (c) Images of the mice bearing the tumors treated with IT-Robo1 + saponin, IT-Robo1, saponin only, and PBS at 10 days: IT-Robo1 + saponin macroscopically delayed the progression of the tumors.
