Here, we examined ADAM12-L and ADAM12-S levels in a panel of breast cancer cell lines, which were previously profiled using two different microarray platforms: an Agilent 4×44K platform (ref. [39], Figure 1A) or an Affymetrix HG-U133A platform (ref. [40], Figure 1B). This evidence concerns the gene ADAM12 and breast carcinoma.
