Abstrakt: MicroRNAs (miRNA) have been implicated in HCV infection. The present study analyzed the effects of let-7g on HCV infection in vitro, in clinical tissue and serum samples. Here, we show that the expression of let-7g in serum and liver tissue is significantly higher in patients with sustained virologic response (SVR). We show that interferon (IFN)/ribavirin (RBV) induces let-7g expression through p38/AP-1 signaling. Overexpression of let-7g reduced HCV gene or core protein level and inhibited the HCV viral load. The let-7g and IFN/RBV have additively inhibitory effect on HCV replication. These data implicate let-7g as a new therapeutic drug to additively cooperate with IFN/RBV to repress HCV replication. Key messages: let-7g expression is increased in serum and liver tissue of patients with SVR. Interferon/ribavirin induces let-7g expression through p38/AP-1 signaling. Overexpression of let-7g can repress HCV replication. Let-7g additively cooperates with interferon/ribavirin to repress HCV replication. Lin28B silencing can reverse let-7g expression and repress HCV replication.
