Quantitative immunohistochemistry analysis of pancreatic adenocarcinoma upregulated factor expression in pancreatic cancer and its prognostic significance

Figure 2 Immunohistochemistry staining results of pancreatic adenocarcinoma upregulated factor in pancreatic cancer patient tissues. A-F: Representative immunohistochemistry images from six pancreatic cancer tissue samples demonstrating varying levels of pancreatic adenocarcinoma upregulated factor (PAUF) expression, assessed by both staining intensity and the proportion of PAUF-positive tumor cells. Samples classified as PAUF-low exhibit staining intensity of 0 or 1+ with ≤ 4% of tumor cells stained, while PAUF-high cases show staining intensity of 1+ or 2+ with > 5% of tumor cells stained. PAUF: Pancreatic adenocarcinoma upregulated factor.
