MMP-9, DJ-1 and A1BG expression analysis by Western blot. Increased MMP-9 (A), DJ-1 (B) and A1BG (C) were detected in the cancerous juice samples compared with cancer-free pancreatic juice samples; MMP-9 expression evinced both 92 kDa and 82 kDa bands, corresponding to the latent and activated forms of MMP-9, respectively.
