Recently, we have found an anomaly of Fig 3B. The results of our invasion assay of A549 cells with transduction with the siRNA-control or the siRNA-KIF20A has shown that no significant suppression of cells infected with siRNA-KIF20A when compared with that of the siRNA-control cells. In this manuscript, this anomalous result was relevant to the conclusion, The KIF20A silence inhibits the invasion of non-small cell lung cancer.
