Effect of AKR1B10 on the migration of NPC cells. a In vitro scratch assay. The same numbers of CNE-2/vector and CNE-2/AKR1B10 cells were cultured in 6-well plates. The bottoms of the plates were scratched when the cells were cultured to confluency. The images were captured at 0, 24 and 48 h. b Histogram of cell migration ratio (MR) calculated by using the equation: MR % = [(Area at T0 − Area at Tt)/Area at T0] × 100 % (t = 24 h or t = 48 h). The experiments were repeated three times at least (*p < 0.05)
