Overexpression of LINC01146 has shown to inhibit tumor growth, whereas its reduction encourages tumor growth.[29] Different cancers, like lung, liver, and breast cancers, have shown a connection with either the promotion or inhibition of lncRNAs.[30, 31, 32] Owing to this, lncRNAs have been identified as potential cancer biomarkers.[33] The expression and variability of lncRNAs at the single‐cell level, however, remain unclear. This evidence concerns the gene HISLA and breast cancer.
