^*Ratio of total breast counts to lung counts; libraries used were GSM692, 677, 691, 760, and 780 for normal breast tissue; GSM 670, 671, 672, 673, and 694 for breast cancer tissue, and GSM762 for normal lung tissue. 

^†One article reported low-level of expression in gynecological malignancies, using nested RT-PCR. 

^‡All are invasive ductal carcinoma.
