Figure 6. Effects of RHCG on tumor growth in vivo. (A) Diagram of in vivo assay procedure; (B) Tumor volumes, measured at experiment endpoints in in control and RHCG knockdown or overexpression xenografts (n = 5 for each group). (C) Tumor images at experimental endpoints in control and RHCG knockdown or overexpression xenografts (n = 5 for each group). (D) The tumor sections were under H&E staining and IHC staining using antibodies against ki-67 and RHCG. Bar graphs (mean ± SD) and representative images are shown. *P < 0.05, **P < 0.01, compared with the NC group.
