Figure 3From: The E-cadherin repressor slug and progression of human extrahepatic hilar cholangiocarcinomaA Expression of E-cadherin in QBC939 cells. The reaction product of in vitro ribozyme cleavage was analyzed by absolute real-time quantitative PCR. The amplification plots and standard curve were obtained with the in vitro transcript from E-Cadherin. Serial 10-fold dilutions with 9 × 108 to 9 × 10-2 pg per reaction well were made in EASY Dilution (Takara). Amplification was repeated three times for each dilution. It showed Slug inhibition increased E-cadherin expression in QBC939 cells. B Evaluation of transfection efficiencies. It showed the transfection efficiency was 31.4% 48 h after siRNA-Slug transfection.Back to article page
