doi: 10.1128/spectrum.01388-25

Figure Lengend Snippet: Determine the roles of FASN in BoAHV-1 productive infection in MDBK cells using a chemical inhibitor. ( A and C ) MDBK cells in six-well plates were infected with BoAHV-1 (MOI = 1) and treated either with DMSO control or with the FASN-specific inhibitor Cerulenin at the indicated concentrations. At 24 hpi, the cells were collected either to prepare cell lysates for Western blotting using an antibody against virus-associated proteins (VMRD, cat# P170703-001, 1:5,000) ( A ) or to extract DNA for subsequent qPCR analysis using gB-specific primers ( C ). ( B ) The intensity of bands for virus-associated proteins was quantified using the freeware software Image J. Changes in the levels of individual bands upon treatment with the inhibitor were calculated relative to those of the DMSO control, which was set at 100%. ( D ) Virus titers in the supernatants were determined and expressed as TCID 50 /mL. ( E ) MDBK cells in six-well plates were infected with the virus at an MOI of 1 for 24 h and treated with either DMSO control or 10 µM Cerulenin. Total RNA was then extracted from the cells for the detection of viral mRNA using RT-qPCR. Primers specific for bICP27, viral DNA polymerase, and viral protein gC were used, respectively. The data shown are means of three independent experiments, with error bars representing standard deviations. Significance was assessed by a standard t -test (ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001).

Figure Lengend Snippet: Determine the roles of FASN in BoAHV-1 productive infection in Neuro-2A cells using both siRNA and chemical inhibitor. ( A ) Neuro-2A cells in six-well plates were transfected with either scrambled siRNA (150 pmol) or individual siRNAs targeting FASN (150 pmol), referred to as siRNA1, siRNA2, siRNA3, and siRNA4, respectively. At 48 h post-transfection, cell lysates were prepared and subjected to Western blot analysis to detect FASN protein levels using an antibody against FASN (Proteintech, cat# 10624-2-AP, 1:10,000). ( C ) Neuro-2A cells in six-well plates were transfected with either scrambled siRNA (150 pmol) or siRNA1 (150 pmol). At 36 h post-transfection, the cells were infected with BoAHV-1 at an MOI of 10. After 24 h of infection, the cells were collected and subjected to Western blot analysis using a monoclonal antibody against viral protein gC (VMRD, cat#F2, 1:2,000). ( E ) Neuro-2A cells in six-well plates were infected with BoAHV-1 (MOI = 10) and treated either with DMSO control or with the FASN-specific inhibitor Cerulenin at the indicated concentrations. At 24 hpi, the cell lysates were prepared and subjected to Western blotting to detect viral protein gC. ( B, D, and F ) The band intensities were quantified using the free software Image J. The intensity of each band was first normalized to that of the respective loading control Tubulin, and then normalized to that of either DMSO-treated or scrambled siRNA-transfected control, which was arbitrarily set to 100%. The data shown are means of three independent experiments, with error bars representing standard deviations. Significance was assessed using a Student’s t -test (ns, not significant; * P < 0.05; ** P < 0.01).

Figure Lengend Snippet: Determine the effects of FASN inhibitor, Cerulenin, on the accumulation of gD in the Golgi apparatus. ( A ) Diagram shows the treatment manner of virus-infected cells by both Cerulenin and Monensin. ( B ) MDBK cells of either mock-infected or virus-infected were treated either with vehicle control DMSO or with Cerulenin (10 µM) or Monensin (10 µM) for a duration of 4 h prior to the termination of infection. At 24 hpi, the cells were collected to purify the Golgi apparatus using a commercial purification kit (Beijing Biolabo Technology, cat# HR0247-50T). Subsequently, Western blot analysis was performed to detect the protein levels of gD in the Golgi fractions. GOLGA1, a marker of the Golgi apparatus, was used as a loading control and for subsequent quantitative analysis. ( C ) The band intensity was analyzed with the free software Image J. The intensity of each band was first normalized to that of the respective loading control GOLGA1, and then normalized to that of the control treated with DMSO, which was arbitrarily set to 1. The data shown are means of three independent experiments with error bars indicating standard deviations. Significance was assessed with a Student’s t -test (* P < 0.05, ** P < 0.01).
