Knockdown of IQGAP1 expression inhibits proliferation of ESCC cells.

<p>(A–B) MTT proliferation assay. Equal numbers of cells were cultured and monitored for growth over time. Each graph indicates the average number of viable cells assessed at 2, 4, 6, 8 or 10 days. The data shown represent mean±SD from three independent experiments. (C) Representative images of the colony formation assay were shown. (D) The histogram represents number of colonies of the results of 3 independent experiments (mean±SD). *, Statistically different, compared with the control cells (<i>P</i><0.05).
