Among the 30 identified GI-lncRNAs, six upregulated lncRNAs (DLX6-AS1, ELFN1-AS1, MIR2052HG, TRPM2-AS, LINC01224, and CALML3-AS1) were found in the database, with functions predominantly linked to ceRNA activity, miRNA sponging, and transcriptional regulation across various cancer types, including NSCLC and LUAD. The gene discussed is ELFN1; the disease is cancer.
