Fig. 6. USP22 promotes HCC progression in mice.
A Pictures showed all the xenograft tumors formed by HCCLM3 cells in different groups. VEGFA-165 stands for recombinant human protein VEGFA-165. B The image closely up displays the tumors in situ, with yellow arrows indicating blood vessels forming on the tumor surface. C Growth curves drawn by tumor volume of xenograft tumors in the USP22 knockdown group and the control group at indicated time. D Tumor weight of xenografts in indicated groups were shown. E Protein levels of USP22, VEGFA and ZEB1 in every xenograft tumor were detected by western blotting. GAPDH was used as a control. F The protein expression of ZEB1 from (E) was quantified by densitometry, with GAPDH as the reference. P < 0.05 is considered statistically significant. G Pictures showed all the xenograft tumors formed by HCCLM3 cells in different groups. H Growth curves drawn by tumor volume of xenograft tumors in the USP22 overexpressing, USP22 overexpressing with ZEB1 deletion, and the control group at indicated time. I Tumor weight of xenografts in indicated groups were shown. J Protein levels of USP22, and ZEB1 in every xenograft tumor were detected by western blotting. GAPDH was used as a control.
