Fig. 2From: In epithelial cancers, aberrant COL17A1 promoter methylation predicts its misexpression and increased invasionCollagen XVII is underexpressed in breast cancer. Tissue microarrays with a total of 57 normal breast tissues, 20 hyperplastic breast tissues, and 150 breast ductal carcinomas were stained with an anti-collagen XVII antibody [15, 16]. Numbers of samples in each category, as well as the total number of samples, are indicated. Percentages indicate frequencies of observations per row. Scale bar, 50 μmBack to article page
