Abstract  Objective:To establish Aurora-A overexpressing transfectant clones and investigate its effect on invasiveness as well as protein expression and activity of MMP-9 in esophageal carcinoma cells. Methods:The Aurora-A expressing plasmid was transfected using LipofectamineTM 2000 and the identification of transfected clones was confirmed by Western blot analysis and RT-PCR. The invasive properties of cells were examined by an in vitro Boyden chamber invasion assay. Level of MMP-9 protein expression and activity were measured with Western blot and ELISA as well as gelatin zymography analysis. Results:Aurora-A overexpressing transfectant clone was established, which increased cell invasion as well as protein expression and activity of MMP-9. Conclusion:The elucidation the molecular mechanism for the promotion of invasion in esophageal carcinoma by Aurora-A may lead to the development of new target for effective therapy.
