High expression of ErbB2 contributes to cholangiocarcinoma cell invasion and proliferation through AKT/p70S6K

Figure 4 Inhibition of ErbB2 expression by siRNA against ErbB2. A: KKU-M213 cells were transfected with siErbB2 and the levels of ErbB2 at 0-96 h after transfection were determined by Western blotting; B: After 72 h of siRNA transfection, ErbB2 expression in HuCCA-1, KKU-100, and KKU-M213 cells was determined. Scramble siRNA (siNeg) was used as a negative control. The results shown are representatives of two (A) and three (B) separate experiments.
