Abstract
Influenza A viruses (IAVs) significantly impact animal and human health due to their zoonotic potential. A growing body of evidence indicates that the host's long noncoding RNAs (lncRNAs) play crucial roles in regulating host-virus interactions during IAV infection. However, numerous lncRNAs associated with IAV infection have not been well characterised. Here, in this study, we identify the LINC01197 as an antiviral host factor. LINC01197 was significantly upregulated after IAV infection, which is controlled by the NF-κB pathway. Functional analysis revealed that overexpression of LINC01197 inhibited IAV replication and virus production, while knockdown of LINC01197 facilitated IAV replication. Mechanistically, LINC01197 directly interacts with poly(A) binding protein cytoplasmic 1 (PABPC1), which in turn sequesters and restricts its functions. This work shows that LINC01197 acts as a protein decoy, suppressing IAV replication and playing a key role in controlling IAV replication.
