Abstract:
Objective To investigate the expression of p 120-catenin in human bladder cell line BIU-87 and T24.And to explore the effect of down-regulation of p120-catenin on proliferation, invasion and adhesion of BIU-87 cell line. Methods The study was from Aug .2010 to May.2011.Real-time RT-PCR and Western blot were used to examine the expression of p 120-catenin in human bladder cell line BIU-87 and T24.There were three study groups:non-transfected group , the group transfected with p 120-catenin siRNA and the group transfected with control siRNA .p120-catenin siRNA was used to decrease the expression of p120-catenin.MTT assay and colony formation assay were used to study the BIU-87 cell growth and cell pro-liferation.The invasion of BIU-87 cells was measured by Transwell chamber assay .Cell adhesion artificial re-constituted basement membrane assay was used to examine the change of BIU-87 cell adhesion capacity . Results In both BIU-87 and T24 cells there were the expressions of p 120-catenin.But the expression in BIU-87 cells (0.11±0.39) was more than that in T24 cells (0.48±0.17).The decreased of p120-catenin ex-pression could enhance the proliferation (182.7±13.4%) and the invasiveness (217.5±15.9) and decrease the adhesion capacity (57.3±6.4%) of BIU-87 cells. Conclusions There is higher expression level of p120-catenin in lower-grade malignant bladder cancer cells .The down-regulation of p120-catenin promotes the bladder cancer proliferation and invasiveness of bladder carcinoma cells , and inhibited the bladder canc-er cell adhesion .
