Searching through the ISOexpresso database (http://wiki.tgilab.org/ISOexpresso/)48, we found that BPAG1, BPAG1eA and BPAG1e were all expressed in normal breast tissues and were reduced by 29, 2.9 and 37 folds, respectively, in breast tumour samples (Fig. 7B). This evidence concerns the gene DST and breast neoplasm.
