In an integrated analysis on the dosage effect of lncRNAs in lung adenocarcinoma, Wei et al. [130] found that the protein coding genes CTSS, FGL2, and PDCD1LG2 (alias PDL2) competed with HCP5 (ENSG00000206337) and formed a single regulatory subnet with the miRNAs miR-106b-5p and miR-17-5b. This evidence concerns the gene PDCD1LG2 and lung adenocarcinoma.
