Fig. 6. The effects induced by CSN6 silencing were abrogated by downregulation of UBR5 expression in CSN6-knockdown cells.

A Total cellular extracts from CSN6-knockdown and UBR5-knockdown CSN6-knockdown A375 and MV3 cells were prepared and subjected to western blotting with the indicated antibody. B The migration and invasion of CSN6-knockdown and UBR5-knockdown CSN6-knockdown A375 and MV3 cells were quantified. C The growth curves of CSN6-knockdown and UBR5-knockdown CSN6-knockdown A375 and MV3 cells are shown (n = 4). D An in vitro colony formation assay was performed with CSN6-knockdown and UBR5-knockdown CSN6-knockdown A375 and MV3 cells. E, F Stably transfected CSN6-knockdown or UBR5-knockdown CSN6-knockdown A375 cells (1 × 106 cells) or control cells were subcutaneously injected into right dorsal side of female nude mice (n = 6). Tumor volume was measured when the tumors reached a certain volume. Two weeks after injection, the mice were sacrificed, and the tumors were collected and weighed. One-way ANOVA. G Immunohistochemical analysis was conducted to detect CSN6, UBR5, CDK9 and Ki-67 expression, Scale bar = 100 μm. H The model of the CSN6-UBR5-CDK9 axis is shown. All data are shown as the mean ± SD, *P < 0.05, **P < 0.01, and ***P < 0.001. All P-values are based on control versus treatment comparisons.
