Therapeutic study of Jac-A in the K562-bearing mice (n = 10/group). (A) Tumour volume plot of K562-bearing mice treated with vehicle or Jac-A at 2, 10, or 50 mg/kg by oral gavage for 21 days. The tumours were measured twice per week. The data are represented as the mean ± SEM. Tumour growth was inhibited significantly after treatment with Jac-A compared with the control group. *, P < 0.05; †, P < 0.01; ‡, P < 0.001 compared with the control group. (B) Selected nude mice models of different groups treated with Jac-A or vehicle at day 14 after therapy. (C) Sizes of selected tumours harvested from dead nude mice bearing K562 cells from different groups treated with the vehicle or Jac-A. (D) Kaplan-Meier survival plot of the K562-bearing nude mice. The survival of the K562-bearing nude mice was prolonged in the Jac-A treated groups compared with control group. (E) Body weight plot of the K562-bearing nude mice. The data are represented as the mean ± SEM. *, P < 0.05; †, P < 0.01; ‡, P < 0.001 compared with the control group.
