Sirtuin-modulating drugs impact influenza virus H1N1 virus replication. (A) EX-527 enhances influenza A virus replication. MDCK cells were infected with influenza A virus PR8 (0.001 TCID50/cell) and treated with EX-527 at 1 hpi. Virus yield was determined at 24 hpi. (B) Resveratrol inhibits influenza A virus replication. MDCK cells were infected with PR8 (0.1 TCID50/cell) and treated with resveratrol (50 µM) at 1 hpi. Virus yields were determined as for panel A. MDCK cells were treated with sirtuin modulators or DMSO for 24 h. Cell viability was assessed using a colorimetric tetrazolium reduction assay. For all experiments: **, P < 0.01; *, P < 0.05.
