Fig. 7

A Real-time PCR was used to evaluate the mRNA level of UBE2C in retinoblastoma cell lines. B The protein levels of UBE2C were detected by western blot in retinoblastoma cell lines. C Knockdown of UBE2C protein in Y79 cells was assessed by western blot. D Knockdown of UBE2C inhibited the proliferation of Y79 cells. **P < 0.01, ***P < 0.001. E A soft agar assay was used to assess the tumour formation ability in vitro. Small colonies were observed and counted under the microscope. Colonies were photographed (left panel) and quantified (right panel). Scale bar: 100 μm. F A colony formation assay was performed to determine the colony formation influence of UBE2C-knockdown Y79 cells. Colonies were photographed (left panel) and quantified (right panel). G Top: Eye weight of the orthotropic xenograft formed by UBE2C-knockdown and Control Y79 cells injected at 30 days after implantation; n = 6, ***P < 0.001. Bottom: H&E staining to evaluate tumour formation. Scale bar: 250 μm. H Representative image of tumour bearing eyeballs removed from the mice at the 30th day.
