Figure 6From: Investigating AP-2 and YY1 protein expression as a cause of high HER2 gene transcription in breast cancers with discordant HER2 gene amplificationAP-2α/β, YY1 and Her-2 immunostaining. Weak AP-2α/β (a) and YY1 (b) expression but strong (3+) Her-2 staining (c) is seen in this tumour. (×20 magnification)Back to article page
