The genes C16orf5 [GenBank:NM_013339], GOSR2 [GenBank:NM_004287], and TXNL2 [GenBank:AL138831] were upregulated, and LOX [GenBank:NM_002317] and SULF-1 [GenBank:NM_001128206] were downregulated in pure DCIS in comparison with in situ component of DCIS-IDC. This evidence concerns the gene GLRX3 and ductal breast carcinoma in situ.
