Abstract
Objective: To investigate the effect of Tip60 gene silencing on the ABCE1 acetylation level and cell proliferation, migration and invasion in TE-1 cells of oesophageal cancer. Methods: The siRNA sequence of Tip60 was transfected with esophageal cancer TE-1 cells. Transfected siRNA vector cells were used as experimental group (si-T), siRNA no-loaded somatic cells were transfected as control group (si-NC), and untransfected TE-1 cells were used as blank group (Group N). ABCE1 mRNA was detected by qRT-PCR, the expression of ABCE1 protein, proliferation-related protein β catenin (β-catenin), GSK3β, and c-myc by Western blot, the protein acetylation level by immunoprecipitation, MTT assay for cell viability, scratch healing and Transwell compartment assay for migration and invasion ability. Results: After 48 h downregulation of the Tip60 gene, TE-1 cells showed no significant changes in the ABCE1 mRNA and protein expression. The acetylation level of ABCE1 decreased significantly, compared with the control group and the blank group. After Tip60 gene silencing, the expression of β-catenin and c-myc protein decreased, while the expression of GSK-3β protein increased. Cytofunctology experiments showed that the proliferative activity, migration and invasion ability of TE-1 cells in the experimental group were significantly inhibited. Conclusion: Down regulation of Tip60 gene can deacetylate ABCE1 protein and inhibit the proliferation activity, migration and invasion ability of esophageal cancer by blocking the conduction of Wnt signaling pathway.Keywords
