Expression of MUC1 protein studied by IHC on a tissue-microarray. A: H&E staining of a paraffin block section (25 × 30 mm) from the TMA containing 647 arrayed samples, including 592 tumors and 55 controls. B: MUC1 staining: normal breast tissue (left), apical (middle), and cytoplasmic (right) staining in tumors. C: Kaplan-Meier plot of patient overall survival: survival differs significantly according to MUC1 protein localization. A: Absence of staining or apical localization; B: cytoplasmic or circumferential membrane localization.
