Expression Pattern and Prognostic Impact of Glycoprotein Non-Metastatic B (GPNMB) in Triple-Negative Breast Cancer

Among 759 specimens, immunohistochemistry exhibited glycoprotein non-metastatic B (GPNMB) expressions were variable in different subtypes and significantly higher in TNBC. GPNMB positively correlated with epithelial–mesenchymal transition regulators, mesenchymal marker vimentin, MMP and integrins.
