Numerous lncRNAs are functionally correlated with ED and its associated diseases in recent studies, such as highly upregulated in liver cancer (HULC) [49,50], metastasis associated lung adenocarcinoma transcript 1 (MALAT1) [51,52,53,54,55,56,57,58,59,60], maternally expressed 3 (MEG3) [61,62,63,64,65,66,67,68], taurine up-regulated 1 (TUG1) [69,70,71], plasmacytoma variant translocation 1 (PVT1) [72,73], ANRIL (CDKN2B-AS1) [74,75], HOTAIR [76,77], retinal non-coding RNA3 (RNCR3) [78,79], X-inactive specific transcript (XIST) [80], and H19 imprinted maternally expressed transcript (H19) [81]. Here, PVT1 is linked to liver cancer.
