Figure 1. Effect of si-EpCAM and/or 5-FU treatment on cell viability in vitro.

Figure 1

MCF-7 cells were treated with 5-FU (7.5 µg/ml and 20 µg/ml) and/or si-EpCAM. A. MCF-7 cells were treated with si-EpCAM, the expression of EpCAM was detected. A negative siRNA control and Lipofectamin 2000 were served as control. B. Cell viability was detected with the CCK-8 assay. Cell viability was expressed as a percentage of control cells (MCF-7 cells). B. The results are presented as the inhibitory ratio of MCF-7 cells. *P<0.05.
