The heatmap of these 11 autophagy‐related lncRNA expressions in breast cancer samples showed that C6orf99, LINC00992, Z68871.1 and LINC00578 were highly expressed in the high‐risk group, while U62317.4, LINC01016, LINC02166, BAIAP2‐DT, AC245297.3, AC090912.1 and LINC01871 were up‐regulated in the low‐risk group (Figure 2D). Here, LINC02166 is linked to breast cancer.
