Abstract:
Objective To study the effect of wild type p53 gene on centrosome hyperamplification in bladder cancer cells.Methods A wild type p53 gene recombinant adenovirus vector AdCMVp53 was constructed,and then trangfected into the human bladder cancer cell line T24.The cells were stained with the monoclonal antibody against pericentrin by indirect immunofluorescence method.The change of centrosome hyperamplification was observed under the fluorescence microspcope.Results Introduction of wild type p53 could suppress the centrosome amplification of T24 cell line.Conclusion p53 might play an important role in the regulation of centrosome hyperamplification.The loss of p53 might be one of the mechanisms involved in chromosome instability and contribute to the genesis and development of the bladder carcinoma.
