Hepatitis C Virus (HCV) infection-induced liver disease is a growing problem worldwide, and is the primary cause of liver failure requiring liver transplantation in North America. Improved therapeutic strategies are required to control and possibly eradicate HCV infections, and to modulate HCV-induced liver disease. Cellular microRNAs anneal to and regulate mRNA translation and stability and form a regulatory network that modulates virtually every cellular process. ⋯ We also discuss a few miRNAs that might be targets to treat HCV in cases of HCV/HIV co-infection. Finally, we review methods to deliver miRNA antagonists and mimics to the liver. In the future, it may be possible to design and deliver specific combinations of miRNA antagonists and mimics to cure HCV infection or to limit liver pathogenesis.
