From: Reduced PTEN expression predicts relapse in patients with breast carcinoma treated by tamoxifen
(a) PTEN is strongly expressed in the nuclei of the breast cancer cells as well as in the benign duct epithelial cells (right lower corner). (b) PTEN staining is barely detectable in the neoplastic cells, while strongly expressed in the benign duct epithelial cells.
