LncRNA XIST (X-inactive specific transcript) inhibits miR-124 in three types of cancer: bladder cancer, laryngeal squamous cell carcinoma, and tongue squamous cell carcinoma, which activates AR (androgen receptor), EZH2 and JAG1 (jagged 1) proteins [94,95,96]. The gene discussed is AR; the disease is tongue squamous cell carcinoma.
