Figure Lengend Snippet: C2768S mutation abolished the effects of UBR5 on the migration and invasion of HCT116 cells. (A) C2768S mutation changed the expression of epithelial–mesenchymal transition marker genes. HCT116 cells were transfected with UBR5-Myc and UBR5 C2768S-Myc constructs. Cells were collected and subjected to immunoblotting analysis and quantitative reverse transcription PCR analysis for indicated epithelial and mesenchymal markers. ∗∗ P < 0.01 and ∗∗∗ P < 0.001. (B) Immunofluorescence analysis of Snail and E-cadherin protein expression in Mock, UBR5-Myc, and UBR5 C2768S-Myc in HCT116 cells (Snail, green; E-cadherin, red; DAPI, blue). Scale bar: 50 μm. (C) Wound-healing assays showed the migration of HCT116 cells transfected with Mock, UBR5-Myc, or UBR5 C2768S-Myc. Representative images of healing degrees at 0 and 48 h after performing the wound are shown. The histogram shows the quantitation of the relative healing degrees ( n = 3). Scale bars: 100 μm. (D) Transwell assays showed the invasiveness of HCT116 cells transfected with Mock, UBR5-Myc, or UBR5 C2768S-Myc. Representative images of the staining of the cells that invaded and migrated through the matrix layer are shown. The histogram shows the quantitation of the relative numbers of cells that invaded and migrated through the matrix layer ( n = 3). Scale bars: 100 μm. (E) Wild-type UBR5 tumors were smaller in volume and weight than the HCT116 Mock and C2768S mutant groups. The photographs show the excised tumors from HCT116 Mock, UBR5, and UBR5 C2768S models ( n = 4). The tumor sizes (tumor volumes and weights) were subjected to comparison. (F) The UBR5 C2768S mutation disrupted the UBR5-Snail axis, eliminating its regulatory effect on tumor cell invasion. Hematoxylin-eosin staining of xenograft tumors derived from HCT116 Mock, UBR5-Myc, and UBR5 C2768S-Myc cells. Scale bar: 50 μm.
