The cover demonstrates immunohistochemical labeling of inhibin-β A overexpression (brown color) in pancreatic adenocarcinoma cells, but not in adjacent normal stroma and epithelium. Inhibin-β A is one of many genes found by Dengfeng Cao and colleagues using bioinformatics analyses of ESTs overexpressed in pancreatic adenocarcinomas. This study demonstrates that bioinformatics tools can be used to characterize differentially overexpressed ESTs, and that some of these ESTs may be diagnostically and therapeutically useful targets that might be missed using data from currently annotated databases.
