N-myc downstream-regulated gene 1 facilitates influenza A virus replication by suppressing canonical NF-κB signaling

The highly pathogenic avian influenza (HPAI) A/H5N1 virus hijacks host cellular machinery to complete its life cycle; identification of the host factors involved in viral replication may facilitate antiviral drug development. Here, we first characterize a metastasis suppressor, N-myc downstream-regulated gene 1 (NDRG1), and showed that it plays a crucial role in H5N1 viral replication. We found that H5N1 infection upregulated NDRG1 mRNA and...
