(A, B) ZEB1 expression was quantitated by real-time RT-PCR in the parental PC9 cells (P) and PC9-MTA cells (A) and the parental H1993 (P) cells and H1993-MTA cells (B) transfected with control si-RNA (si-control) and siRNA targeting ZEB1 (si-ZEB1). (C, D) Sensitivity to pemetrexed was measured in parental (P) and PC9-MTA cells (C) and in parental H1993 (P) and H1993-MTA cells (D) transfected with each si-RNA (si-control and si-ZEB1) using the WST assay. The error bars in each graph represent the standard error of the value obtained in the experiments performed in triplicate. (E) Western blot analysis of the expression of EMT marker proteins in PC9-MTA and H1993-MTA cells transfected with si-control or si-ZEB1. β-actin was used as a loading control.
