By identifying lncRNA expression characteristics in sample data where gastric cancer (GC) occurred with lymph node (LN) metastasis, they found 10 characteristic lncRNA features, including 5 lncRNAs that are relatively highly expressed in lymph node metastasis samples—H19, CECR7, HOTAIR, FAM66D, C22orf34—and 5 lncRNAs that are relatively lowly expressed—TTTY15, TTTY14, TP53TG1, HAR1A, C10orf95. The gene discussed is C10orf95; the disease is gastric cancer.
