Fig. 7From: Paracrine and epigenetic control of CAF-induced metastasis: the role of HOTAIR stimulated by TGF-ß1 secretionOverexpressed HOTAIR correlated with poor prognosis in breast cancer. a HOTAIR expression was analyzed by FISH. Scale bars in all images: 15 μm. b Immunohistochemistry staining detected EZH2, CDK5, CDK5RAP1 and EGR-1 expression in 59 breast carcinoma samples (39 with lymph node metastasis, 19 in situ carcinoma)Back to article page
