Fig. 7: ARHGAP15 hyperexpression suppressed the formation and distant metastasis of CRC in vivo.

CRC xenograft mouse model was established to validate the antitumor effect of ARHGAP15 overexpression in vivo. Two groups were divided according to the subcutaneously injection of pLVX-NC or pLVX-ARHGAP15 transfected RKO cells to nude mice (six mice per group). a The pictures of the tumor-bearing mice and tumors. b Tumor growth curves of the two groups. c Western blot analysis of the crucial molecules in the tumors. d HE staining of lung metastases. Scale bar: 100 μm. NS: no significant difference; *P < 0.05; **P < 0.01; *** P < 0.001
