ZC3H12A and hepatocellular carcinoma: Hepatitis B virus (HBV) induces Lin‐28 homolog to downregulate let‐7 expression in HepG2 hepatoma cells, potentially hindering HBV replication.[52, 53] MCPIP1 inhibits Kaposi's sarcoma‐associated herpesvirus (KSHV) infection by directly degrading viral miRNA precursors.[54] However, MCPIP1 expression is repressed upon KSHV infection.[55]
