Figure 1From: Reduced expression of p21-activated protein kinase 1 correlates with poor histological differentiation in pancreatic cancer Immunohistochemistry of PAK1 expression in human primary pancreatic cancer tissues and metastatic liver samples. Original magnifications: ×100 (left column) and × 200 (right column). (a) Representative images showing very weak cytoplasmic PAK1 staining (brown) in poorly differentiated metastatic pancreatic cancer tissues. (b–d) Representative images showing an obvious trend of increasing cytoplasmic PAK1 staining (brown) in poorly, moderately and well differentiated primary pancreatic cancer tissues, respectively.Back to article page
