Huaier extract suppressed the growth of 4T1 cells in vitro and in vivo. (A) Huaier extract inhibited 4T1 cell proliferation as shown by MTT assay. In the in vivo experiment, the mice were administrated with Huaier extract by gavage daily for 18 days. (B) Tumor images after mice were sacrificed. (C) Inhibition of tumor growth judging from the final tumor weight. (D and E) Tumor volumes and body weights were measured 7 days later. The bars represent the means ± SD. ^*P<0.05; ^**P<0.01; ^#P<0.05; ^##P<0.01.
