PTPRD and neoplasm: Besides, totally 14 lncRNAs showed differential expressions between cancer and adjacent samples, among which 13 lncRNAs (CADM3-AS1, DNM3OS, EMX2OS, HOTTIP, ITGA9-AS1, LIFR-AS1, LINC00092, LINC01278, MAGI2-AS3, NR2F2-AS1, PCAT19, PTPRD-AS1, and ZNF667-AS1) had lower expressions in tumor samples and LINC00885 was highly expressed in cancer samples (Figure 4(c)).
