CXCL5/CXCR2 together induces EMT in NPC cells. a The cellular morphologies of the NPC cells with high or low CXCL5/CXCR2 expression. b The influence of the CXCL5/CXCR2 expression levels on cell morphology was confirmed by immunofluorescence assays using phalloidin (green) with DAPI counterstaining (blue). c The results of qRT-PCR and (d) western blot analyses revealed changes in the expression of EMT markers (E-cadherin and Vimentin) in the NPC cell lines. These experiments were repeated at least three times. Error bars, mean ± SD
