PARP-1 expression in human normal and pancreatic cancer tissues. Expression of PARP-1 in normal and pancreatic cancer tissues was determined by immunohistochemical staining using anti-PARP-1 antibody. (a) Representative images of stained sections from normal (Control) and pancreatic cancer tissues (Pancreatic Cancer) are shown. Higher magnification of the boxed areas are shown below each image. Red arrows indicate nuclear or nuclear/cytoplasmic PARP-1 expression. Scale bars = 100 μm. (b) Quantitative analysis of percentage of tissues that express cytoplasmic PARP-1 in the normal (Control) and grade 1 (G1), grade 2 (G2) and grade 3 (G3) pancreatic cancers. The numbers in the brackets are the numbers of the samples that are positive for cytoplasmic PARP-1 and total samples examined in each group (*p < 0.05, compared to the Control).
