AIM:To investigate the mechanisms by which Cskbinding protein(CBP)inhibits tumor progression in esophageal carcinoma.METHODS:A CBP overexpressing esophageal carcinoma cell line(TE-1)was established.The growth,invasion,and migration of CBP-TE-1 cells,as well as the expression of Src were then determined and compared with those in normal TE-1 cells.RESULTS:The expression of Src was decreased by the overexpression of CBP in TE-1 cells.The growth,invasion,and migration of TE-1 cells were decreased by the overexpression of CBP.CONCLUSION:This study indicates that CBP may decrease the metastasis of esophageal carcinoma by inhibiting the activation of Src.CBP may be a potential tumor suppressor and targeting the CBP gene may be an alternative strategy for the development of therapies for esophageal carcinoma.
