Objective:To investigate whether PLCε gene down regulation by RNA interference(RNAi) leads to inhibition of proliferation in human bladder carcinoma T24 cell.Methods: The shRNA recombinant plasmids targeting to PLCε gene was constructed and transfected into bladder carcinoma T24 cell with Lipofectamine 2000.RT-PCR was used to monitor the validity of specific s h R N A in down regulation of PLCε.Then MTT assay was performed for detecting cell proliferation
the changes of PCNA were analyzed by immunocytochemical method
Electron microscope was used to observe the morphological changes.Results: The specific PLCε shRNA was confirmed to be efficient in silencing PLCε expression.PLCε gene down regulation by the shRNA recombinant plasmids inhibition cell proliferation rate about 78.01%
They were significantly different from that of control group(P<0.01;After transfected the specific recombinant plasmids
PCNA expression was significantly decreased
They were significantly different from that of control group(P<0.01;morphological changes produce apoptotic body.Conclusion: PLCεis likely to be potential molecular target for bladder carcinoma in gene therapy by RNAi.
