Tankyrases positively regulate influenza A virus replication via type I interferon response.

ABSTRACT: Influenza viruses are respiratory pathogens that cause both seasonal and unpredictable pandemic infections in humans. Currently approved anti-influenza drugs target the viral proteins. A recurrent mutation in the influenza genome leads to drug resistance and thus hinders the efficacy of anti-influenza drug treatments. Influenza A virus (IAV) depends on host factors to complete its virus life cycle. Thus, there are increasing interests in antiviral drugs that target host cellular proteins required for virus replication. Poly (ADP-ribose) polymerases (PARPs) are the host factors that modify protein functions by adding ADP-ribose to target proteins. Using the CRISPR activation system, we screened all 17 PARP members for its effects on IAV infection in lung epithelial A549 cells. Tankyrase 1 a
