Based on intersection analysis of 1785 differentially expressed lncRNAs from a microarray of NPC patients with metastatic lymph nodes and primary tumours and 442 SE-lncRNAs (https://rnajournal.cshlp.org/content/23/11/1729.full), Hu et al. identified two SE-lncRNAs (SUCLG2-AS1 and FAM225B). The gene discussed is SUCLG2; the disease is nasopharyngeal carcinoma.
