From: Prolyl isomerase Pin1 promotes survival in EGFR-mutant lung adenocarcinoma cells with an epithelial–mesenchymal transition phenotype

Figure 4

Pin1 is expressed in a gefitinib-resistant pleural lesion obtained from an EGFR-mutant lung cancer patient. Hematoxylin–eosin (H&E) staining and immunohistochemistry for Pin1, Cytokeratin 7, Thyroid transcription factor 1 (TTF-1), and vimentin expression in a primary lung adenocarcinoma and its disseminated pleural lesion that has acquired resistance to gefitinib. Scale bars, 100 μm.
