Q: In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
Context: Persistent infection with hepatitis C virus (HCV) leads to chronic hepatitis and hepatocellular carcinoma (HCC). RNA interference (RNAi) may act as a host antiviral response against viral RNA.', 'The effects of RNAi on both the replicative intermediates and the internal ribosome entry site (IRES) of HCV were studied by using HCV-related short interfering RNA (siRNA) detection assay. The mechanism that permits HCV to escape RNAi was studied by using RNAi assay materials.', 'These studies demonstrate that the Dicer, an RNase enzyme that generates short siRNA, can target and digest both the IRES and the replicative intermediate of HCV into siRNA of approximately 22 nucleotides. Further studies also show that Dicer can inhibit the replication of the HCV subgenomic replicon. However, the HCV core protein inhibits this RNAi and rescues the replication of the HCV subgenomic replicon through a direct interaction with Dicer.\Question: Is hepatitis C virus core protein a potent inhibitor of RNA silencing-based antiviral response?
A:
RNAi is a limiting factor for HCV infection, and the core protein suppresses the RNA silencing-based antiviral response. This ability of the core protein to counteract the host defense may lead to a persistent viral infection and may contribute to the pathogenesis of HCV.
