Figure 3: PHO-S treatment started at day 10 after tumor cells injection and was continued every other day until day 50 and measurements of tumor dimensions were estimated on alternate days. PHO-S 7 mg/Kg and 14 mg/Kg reduction significantly of tumor volume compared with Taxol 7 mg/Kg and control group. Kaplan–Meier survival estimates for the cohort of mice treated with PHO-S, as compared with control and Taxol (B). The statistic unpaired t-test showed ***P < 0.001 for all experimental groups treated with PHO-S as compared with control and Taxol.
