Wang et al. reported that down-regulation of miRNA-873 expression significantly enhances glioblastoma tumourigenesis and metastasis via promoting the expression of IGF2BP1, and the overall survival rate of patients with miRNA-873 down-regulation was dramatically shorter than that of patients with miRNA-873 up-regulation (Ren-Jie et al. 2015). The gene discussed is IGF2BP1; the disease is glioblastoma.
