Except for AP000442.2 and OTUD6B − AS1, lncRNAs, including AC136475.2, AC245297.3 (p < 0.001), AL122010.1 (p < 0.001), AL161646.1 (p < 0.001), LINC00578 (p < 0.001), and LINC01871 (p < 0.001), were differently expressed between different breast cancer molecular types (Fig. 4e). This evidence concerns the gene OTUD6B and breast cancer.
