PKIB overexpression promotes the migration and invasion of NSCLC cells. (a) Transwell experiments showed that A549 cell migration was obviously potentiated by PKIB overexpression. (b) Quantitative analysis of the number of migrating cells among the groups. (c) Overexpression of PKIB enhanced the invasion of A549 cells. (d) Quantitative analysis of the number of invading cells among the groups. All values are denoted as the means ± S.E.M. from three independent batches of cells (n = 3, *P < 0.05).
