In addition, six lncRNAs were excluded from subsequent experiments due to their lack of annotation in National Center for Biotechnology Information database, namely AC005034.3, LINC01711, AL122010.1, AC104971.3 and AC012615.1, or their absence of significant expression differences between adjacent and tumour tissues, such as GAS6‐AS1 (Figure S1). This evidence concerns the gene GAS6 and neoplasm.
