The effect of PGNS on the scratch assay and migration of SK-BR-3 cells. a The images of the scratch assay captured by an inverted fluorescence microscope (with 4× magnification, scale bar = 500 μm). b The wound healing (%) of a scratch assay calculated by Image J. c The OD value of cells migrated through the membrane in the migration assay; and d, e Western blotting of E-cadherin, N-cadherin and snail proteins in tumour tissues (^*p < 0.05, ^**p < 0.01, ^***p < 0.001)
