Our bioinformatics analysis revealed that the LINC01405 expression level in cell lines of breast cancer to some extent follows the breast cancer tissues subtype pattern, where the highest expression of this lncRNA was observed in MDA‐MB‐231(Triple‐negative cell line) compared to the Her2‐enriched and the Luminal A cell line, (SKBR3) and (MCF7) (Figure 6A right). This evidence concerns the gene ERBB2 and breast carcinoma.
