This study explored whether 4HPR restrained the infiltration of bladder cancer cells through regulating the expression of E-Cad. The infiltrating bladder cancer cells T24 were cultured, and then treated by a proper dosage of drug. Their viability was a determined by MTT method. Western blotting and RT-PCR were adopted to detect the changes of E-Cad gene expression at both protein and mRNA levels. Moreover, immunofluorescent staining and confocal fluorescence microscopy were employed for the observation of the expression of E-Cad. The result showed that, at both mRNA and protein levels, the expression level of E-Cad in T24 cells treated by 4HPR was significantly higher than that of control group, while the β-Cat expression was also relocated from the cell nucleus to cytoplasm. Our findings suggested that the regulatory function of 4HPR on infiltration of bladder cancer cells T24 is at least partly achieved by regulating the expression of E-Cad.展开更多
