Figure Lengend Snippet: SMYD3-SMAD3 promotes colon cancer cell metastasis in vitro and in vivo dependent on RACK1. A Wound healing assay shows the effect of RACK1 knockdown on vector-, SMYD3-overexpressing and SMAD3-overexpressing RKO and HCT116 cell metastases. B Transwell assay shows the effect of RACK1 knockdown on vector-, SMYD3-overexpressing and SMAD3-overexpressing RKO and HCT116 cell metastases. C Wound healing assay shows the effect of RACK1 overexpression on vector-, SMYD3- knockdown and SMAD3- knockdown RKO and HCT8 cell metastases. D Transwell assay shows the effect of RACK1 overexpression on vector-, SMYD3- knockdown and SMAD3- knockdown RKO and HCT8 cell metastases. E The schematic diagram of tail vein lung metastasis model construction. F Representative living images of mice injected with HCT116 transfected by indicated lentivirus into tail vein. The lentivirus was Luci-labelled and therefore stably transfected HCT116 cell lines had in vivo luciferase activity. G Statistical analysis of luciferase bioluminescence intensity ( n = 5). H Statistical analysis of the number of pulmonary metastases of each group ( n = 5). I Representative images of metastases in murine lung of each group and H&E staining of pulmonary tissue sections; The black arrow indicated the metastasis. For A,B,C and D, significance was determined with the Two-way ANOVA. For G and H, significance was determined with the student unpaired t test. ns, not significant, p > 0.05; *, p < 0.05; ***, p < 0.001; ****, p < 0.0001. Errorbars, ± SD
