    Transient overexpression of CerS4 impairs productive infection of influenza viruses. ( A ) HEK293FT cells were transfected with control plasmid (−) or plasmid encoding Myc-tagged CerS4 (+). The cells were mock-infected or infected with IAV (pH1N1) at an MOI of 1 at 18 hours post-transfection. At 24 hpi, cells were harvested, and Western blotting was performed to detect the levels of IAV-HA, PB1, NS1, M1, Myc-tagged CerS4, and GAPDH. Densitometric values are shown, with relative expression of viral protein/GAPDH in vector control and infected samples set to 1.0. The effect of CerS4 overexpression in infected cells was compared. ( B ) A549 cells were transfected with vector control or CerS4-encoding plasmid. At 18 hours after transfections, cells were mock-infected or infected with pH1N1 at an MOI of 3 for 8 hours. Expression levels of viral proteins were assessed as shown in panel ( A ). ( C–E ) A549 cells were transfected with a vector control plasmid (Control) or plasmid encoding CerS4 (CerS4) or plasmid encoding CerS1 (CerS1, only). In ( C ), at 18 hours post-transfection, the cells were infected with IAV pH1N1 at an MOI of 0.01. At 1 ( n = 7/group), 2 ( n = 3/group), or 3 ( n = 6/group) dpi, cellular supernatants were harvested. Control vs CerS1 and Control vs CerS4 titers were statistically analyzed as indicated. In ( D ), A549 cells were infected with IAV pH1N1 at an MOI of 3 for 8 hours, followed by supernatant collection for titration by plaque assay ( n = 3/group). In ( E ), A549 cells were infected with IAV WSN at an MOI of 0.001. Cell supernatants were collected at 2 and 3 dpi for assessing viral titers using plaque assay on MDCK cells ( n = 3/group). Statistical significance was determined by a t -test and is indicated by * P < 0.05, ** P < 0.01, and *** P < 0.001. Data are expressed as means ± SD. ( F ) HEK293FT cells were transfected with control plasmid (−) or plasmid encoding Myc-tagged CerS4 (+) and were infected with influenza B/Lee/40 virus (IBV) or A/Hong Kong/8/68 <t>(H3N2)</t> at an MOI of 1 at 18 hours post-transfection. At 24 hpi, cells were harvested, and Western blotting was performed to detect the levels of IBV NP, IAV NS1, Myc-tagged CerS4, and GAPDH. The data are representative of three independent experiments.
