We confirmed a high expression of Luteinizing hormone/choriogonadotropin receptor (LHCGR) in TGCA data set for breast cancer and in a panel of breast cancer cell lines, however LHCGR was found to be expressed irrespective of β-hCG expression status (Supplementary Figures S8a–c). The gene discussed is LHCGR; the disease is breast carcinoma.
