Figure 5From: Serial analysis of gene expression of lobular carcinoma in situ identifies down regulation of claudin 4 and overexpression of matrix metalloproteinase 9Digital Northern blot of matrix metalloproteinase (MMP) 9 expression in breast long serial analysis of gene expression (SAGE) libraries. Note that the lobular carcinoma in situ (LCIS) library shows higher MMP9 expression than all of the other breast epithelial and stromal libraries, with the exception of a single phyllodes tumour-derived library.Back to article page
