We have previously published individual data for 18 of these 47 genes, namely ERBB1-4 [12]; MYC [13]; TERT [14]; CCND1 [15]; CGB, CGA, ERα, ERβ, PR, PS2 [16]; AR [17]; DNMT3B [18], PAI1, PAI2 and UPA [19], obtained using the same real-time RT-PCR method but in a heterogeneous series of 130 ERα-positive and ERα-negative breast tumors. The gene discussed is TERT; the disease is breast neoplasm.
