SPRR2A promotes TSCC migration in-vitro. a & c Western blotting was performed to examine the protein levels of SPRR1B & 2A in the targeted cells; β-actin was used as control. b & d Cell migration was determined using a transwell assay as described Fig. 2c (the incubation time of the cells here was adjusted to 8 h to avoid high density). Diagrams of migrating cells from the different are shown, which are from more than three independent experiments.*P < 0.05 versus control
