Qi et al. 29 explored the function of miR-30a-3p/5p in esophageal squamous cell carcinoma and determined that the downregulation of miR-30a-3p/5p promotes esophageal squamous cell carcinoma cell proliferation by activating the expression of WNT2 and FZD2. The gene discussed is FZD2; the disease is esophageal squamous cell carcinoma.
