Han et al. reported a ceRNA network composed of DEcircRNAs and then a prognostic risk assessment model was developed based on seven hub genes (PLOD2, TARS, RNF19B, CCT2, RAN, C5orf30, and MCM10), which was verified to be an independent factor for predicting prognosis of HCC [37]. The gene discussed is PLOD2; the disease is hepatocellular carcinoma.
