In the prognostic PRlncRNA risk model, 8 lncRNAs (HOTAIR, LINC00402, SFTA1P, LINC00461, DSCR8, CYP1B1-AS1, LINC00330, ALMS1-IT1) were upregulated, while the other 3 lncRNAs (ZRANB2-AS1, MYB-AS1, TP53TG1) were downregulated in tumor tissues (Fig. 5A). The gene discussed is HOTAIR; the disease is neoplasm.
