For example, lnc-MAFG-AS1 facilitates gastric cancer growth via serving as competing endogenous RNA of microRNA (miR)-505 for polo-like kinase-1 (7); another study has found that lnc-MAFG-AS1 induces ovarian cancer progression by activating NF-κB1-mediated insulin-like growth factor 1 (IGF1) (8). The gene discussed is MAFG; the disease is gastric cancer.
