In recent years, some lncRNAs, including growth-arrest-specific transcript 5 [30] (GAS5), prostate-specific gene 1 (PCGEM1) [31], prostate-cancer-associated transcript 1 (PCAT-1) [32], and colon cancer-associated transcript 2 (CCAT2) [33], have been reported to regulate tumor cell growth and progression by altering the balance between cell proliferation and apoptosis. The gene discussed is CCAT2; the disease is neoplasm.
