ZnPP inhibited tumor growth in the HCt-15-induced tumor xenografts as a potential therapeutic agent. a The mice were treated with PBS, 10 μg or 100 μg of ZnPP three times (day 11, 13, and 16), and the tumor sizes were recorded and compared. We found that 100 μg of ZnPP significantly reduced the tumor growth, and b decreased tumor volume by ~50 %. *p <0.05. **p <0.01
