Abstract
The objective of this study is to reveal the role of KIF3C gene in the proliferation of lung cancer cells, and the regulation of epithelial mesenchymal transition (EMT) of tumor cells. The plate clone formation assay and cell scratch assay were used in this study to detect the changes of cell proliferation and migration ability after siKIF3C interference, while EMT-related protein expression after KIF3C downregulation was detected by Western blot. The cell clone formation assay showed that the number of clones of lung cancer cells A549 was significantly reduced after transfected with siKIF3C (P<0.05); The scratch assay showed that the healing ability of cells was significantly reduced after transfected with siKIF3C (P<0.05); Western blot protein analysis revealed that the levels of EMT-related proteins, N-cadherin, Vimentin, Snail, and Slug were significantly down-regulated (P<0.05), however, E-cadherin protein levels were up-regulated after siKIF3C interference. In conclusion, KIF3C may promote the proliferation and invasive ability of lung cancer cells A549 through EMT.
