For example, miR-122 can promote hepatitis C virus (HCV) proliferation by PLK1-ELAVL1/HuR-miR-122 signaling (63), and anti-miR-122 oligonucleotides has been successfully trialed for treatment of HCV (64), which provides a solid foundation for employing cellular miRNAs in the viral infections. Here, ELAVL1 is linked to viral infectious disease.
