Effects of exogenous PDIA1 and PDIA3 on adhesive interaction between breast cancer cells and different substrates. Effect of exogenous proteins PDIA1 and PDIA3 on adhesion of MCF-7 (A–F) and MDA-MB-231 (G–L) cells to collagen type I, fibronectin and lung microvascular hLMVEC cells, respectively. Data represent mean ± SD of three independent experiments. Statistical analysis was performed using one-way ANOVA followed by Dunnett’s multiple comparisons test (* p = 0.05, ** p = 0.01, *** p = 0.001).
