Fig 4. Percentages of PKM2 and LDHA expression in different tissue types.

PKM2 was strongly expressed by pancreatic cancer tissue specimens and was significantly higher than in normal, pancreatitis, pancreatic cyst and PanIN tissues (P<0.001). Expression of LDHA was significantly higher in pancreatic cancer than in normal pancreas (P<0.001), whereas, there was no significant differences in LDHA expression between pancreatic cancer, PanIN, pancreatic cysts and pancreatitis.
