Pancreas duodenal homeobox-1 expression and significance in pancreatic cancer

Figure 1 Immunohistochemical analysis of PDX-1 expression in different tissues. A: PDX-1-positive cells in pancreatic cancers and located at the leading edge of infiltration; B: Weekly expressed PDX-1 in beta cells but not in ductal cells.

Figure 2 Western blot analysis of PDX-1 expression in different tissues. M: Marker; C: Pancreatic cancer; N: Normal pancreas tissue.

Figure 3 Correlations of PDX-1 mRNA expression with tumor characteristics. C: Cancer tissue; N: Normal tissues; LM: Lymph node metastasis; TNM: TNM staging; PD: Poorly differentiated; MD: Moderately differentiated, WD: Well differentiated.

Figure 4 Expression of PCNA in pancreatic cancer tissues. A: PCNA-positive cells, mainly duct-like cells; B: The proportion of PCNA-positive cells is higher in leading edge of infiltration.
