Interestingly, in our microarray study of 104 breast tumours and normal breast tissue (manuscript in preparation) we identified changes in expression patterns of syndecan adhesion receptors (for review: see [49]) i.e. syndecan 1 is up-regulated, and syndecan 2 is down-regulated, in breast tumours compared to normal breast tissue. The gene discussed is SDC1; the disease is breast neoplasm.
