In the GTEx and TCGA databases, the gene expression levels of six OS-related lncRNAs (LINC00707, LINC00460, FEZF1-AS1, LINC00593, OTX2-AS1, LINC01833, and CASC8) were significantly lower in NSCLC as compared to the normal lung tissues (Fig 6A). Here, OTX2 is linked to non-small cell lung carcinoma.
