Figure 7. PrAg-PCIS toxin is a potent cytotoxic agent for HeLa tumor xenografts.

Figure 7

A. Treatment with PrAg-PCIS toxin inhibits growth of subcutaneous HeLa xenograft tumors in nude mice. Average tumor volumes measured for HeLa tumors injected with 10 μg PrAg-PCIS combined with 5 μg LF or vehicle (PBS alone) on day 11, day 14, and day 17 (indicated by arrows) after inoculation of HeLa cells (day 0). Mice: n = 8 vehicle; n = 9 PrAg-PCIS/LF. B. Tumor weights obtained after resection of tumors in A). C. Dose dependence of PrAg-PCIS toxin in subcutaneous HeLa xenograft tumors. Average tumor volumes measured for HeLa tumors injected with 1 μg PrAg-PCIS, 5 μg PrAg-PCIS, 10 μg PrAg-PCIS, or vehicle (PBS combined with 5 μg LF) on day 13, day 16, and day 19 (indicated by arrows) after inoculation of HeLa cells (day 0). Mice: n = 9 vehicle; n = 8 for each of PrAg-PCIS 1 μg, PrAg-PCIS 5 μg, and PrAg-PCIS 10 μg. D. Tumor weights obtained after resection of tumors in C). *p < 0.05, **p < 0.01.
