To check the underlying mechanism of how AR/miR-122-5p signaling regulates HCC cells progression, we searched the miRDB database (http://mirdb.org/index.html) and predicted 5 potential genes (RABL6, CPEB1, RPL4, CLIC5, NOL4L) that targeted by miR-122-5p. The gene discussed is NOL4L; the disease is hepatocellular carcinoma.
