The heatmap of the expression of these 12 BCSC-related lncRNAs in breast cancer samples showed that Z68871.1, LINC00578, AC097639.1, AP003119.3, AP001207.3 and LINC00668 were upregulated in the high risk group, while AL122010.1, AC245297.3, LINC01871, AP000851.2, AC022509.2 and SEMA3B-AS1 were highly expressed in the low risk group (Fig. 2d). This evidence concerns the gene SEMA3B and breast carcinoma.
