A Boyden chamber assay and wound-healing assay were conducted to determine the invasive and migratory abilities of A549 and H1299 cells. Western blotting was used to analyze the effects of RFC3 overexpression and RFC3 small interfering RNA-induced knockdown, and to explore the potential mechanism and pathway underlying the effects of RFC3. Positive expression of RFC3 was detected in lung adenocarcinoma, and overexpression of RFC3 shortened the survival time of patients with lung adenocarcinoma. Furthermore, overexpression of RFC3 increased the invasion and migration Ro-15-2041 of A549 cells, whereas knockdown of RFC3 significantly reduced the invasion and migration of H1299 cells. Ectopic expression of RFC3 induced epithelial-mesenchymal transition (EMT), as determined by downregulation of E-cadherin, and upregulation of N-cadherin, vimentin and Wnt signaling target genes, including c-MYC, Wnt1 and -catenin, and the ratio of phosphorylated-glycogen synthase kinase 3 (GSK3)- (Ser9)/GSK3-. In conclusion, RFC3 might be considered a coactivator that promotes the Wnt/-catenin signaling pathway, and induces metastasis and EMT in lung adenocarcinoma. tests and improved exploration of the RFC3 system are required in the foreseeable future. STRING data source (38) Ro-15-2041 and WebGestalt data source (39) were useful for bioinformatics evaluation, however, the prospective protein by which RFC3 make a difference the Wnt pathway hasn’t yet been determined (data not demonstrated). Once the focus on protein continues to be identified, we try to research its association with RFC3 em in vivo /em . Finally, the scholarly study is retrospective; consequently, potential research and double-blind control research must verify the existing outcomes additional. Finally, RFC3 manifestation in “regular” lung cells was likened and examined by immunohistochemistry. The ‘normal’ lung tissues came from the paracancerous tissues of the same patients, which might not truly represent normal tissue. In conclusion, these data indicated that reduction or over-expression of RFC3 could attenuate or increase the invasion and migration of lung adenocarcinoma cells, respectively. In addition, this study revealed that RFC3 regulated lung adenocarcinoma biological behavior potentially by inducing EMT via the Wnt/-catenin pathway, and RFC3 expression was closely associated with the clinical outcome of patients with lung adenocarcinoma. These findings suggested that RFC3 may provide a potential anticancer strategy for the treatment of metastasis of advanced lung adenocarcinoma.
