Previous evidence has confirmed that lncRNA SNHG20 increases the proliferation of laryngeal squamous cell carcinoma cells by regulating miR-140 [25]; Wu et al. [28] also found that lncRNA SNHG20 increases the proliferation and invasion of prostate cancer cells by targeting miR-6516-5p. The gene discussed is SNHG20; the disease is prostate carcinoma.
