Fig. 2. (A) Body weight changes of DOX–AuGCs compared with each control group in the HepG2 cell line injected in nude mice models. (B) Tumor volume at different time points. Values were shown as mean ± S.E.M. *p < 0.05 vs. model. (C) Tumor volume of each group at the study end point calculated by ultrasound images. (D) Ultrasound images of the tumor of each group at the study end point. Data are shown as the mean ± S.E.M. *P < 0.05, **P < 0.01, ***P < 0.001 compared to the controls group, as indicated.
