HNRNPA2B1 enhances cell invasion and expression of MMPs in pancreatic cancer cell lines. Mmp7 (a) and Mmp9 (b) were visualised by qRT-PCR and Western blotting (histograms of mRNA expression on pictures of protein levels). β-Actin was used as an internal control. The cell invasion ability c was evaluated in normal cells, cells transfected with a negative lentivirus control and cells transfected with a lentivirus. Cells were counted in 3 randomised 200× fields for invasion (d). Data represent the mean ± SEM, n = 3, *denotes P < 0.05 vs NC groups, ^#denotes P > 0.05 vs NC groups
