    Article Snippet: Two highly selective MEK1/2 inhibitors were used in this study, with the following working concentrations: Binimetinib (MCE, HY-15202, Monmouth Junction, NJ, USA) at 1 μM, and PD0325901 (MCE, HY-10254, Monmouth Junction, NJ, USA) at 0.25 μM.

    Techniques: Expressing, Activation Assay, Modification, Quantitative RT-PCR, Phospho-proteomics, Sequencing, Labeling, Western Blot, Control, Infection

    The MEK/ERK pathway regulates Fos subcellular localization by promoting Fos phosphorylation ( A ) Nuclear-cytoplasmic fractionation combined with Western blot detection of the effects of MEK/ERK inhibitor treatment on the expression levels of phosphorylated Fos (p-Fos Ser362) and total Fos protein in cytoplasm and nucleus of uninfected/ILTV-infected cells. HSP90 was used as a cytoplasm-specific internal reference. Lamin B was used as a nucleus-specific internal reference. Tubulin was used as a whole-cell protein loading internal reference. DMSO was used as the solvent control. BI was the Binimetinib inhibitor group. PD was the PD0325901 inhibitor group. ( B ) Indirect immunofluorescence staining combined with laser confocal microscopy observation of the effects of MEK/ERK inhibitor treatment on p-Fos subcellular localization and expression. Upper panel: representative images showing p-Fos (FITC, green), nuclei (DAPI, blue) and merged fluorescence signals. Scale bar, 20 μm. Lower panel: quantitative analysis of the p-Fos nuclear translocation ratio (n ≥ 50 cells per group). * indicates statistically significant difference between groups ( p < 0.05).

    Figure Lengend Snippet: The MEK/ERK pathway regulates Fos subcellular localization by promoting Fos phosphorylation ( A ) Nuclear-cytoplasmic fractionation combined with Western blot detection of the effects of MEK/ERK inhibitor treatment on the expression levels of phosphorylated Fos (p-Fos Ser362) and total Fos protein in cytoplasm and nucleus of uninfected/ILTV-infected cells. HSP90 was used as a cytoplasm-specific internal reference. Lamin B was used as a nucleus-specific internal reference. Tubulin was used as a whole-cell protein loading internal reference. DMSO was used as the solvent control. BI was the Binimetinib inhibitor group. PD was the PD0325901 inhibitor group. ( B ) Indirect immunofluorescence staining combined with laser confocal microscopy observation of the effects of MEK/ERK inhibitor treatment on p-Fos subcellular localization and expression. Upper panel: representative images showing p-Fos (FITC, green), nuclei (DAPI, blue) and merged fluorescence signals. Scale bar, 20 μm. Lower panel: quantitative analysis of the p-Fos nuclear translocation ratio (n ≥ 50 cells per group). * indicates statistically significant difference between groups ( p < 0.05).

    Article Snippet: Two highly selective MEK1/2 inhibitors were used in this study, with the following working concentrations: Binimetinib (MCE, HY-15202, Monmouth Junction, NJ, USA) at 1 μM, and PD0325901 (MCE, HY-10254, Monmouth Junction, NJ, USA) at 0.25 μM.

    Fos acts as a core direct transcriptional repressor of metabolic genes downstream of the MEK/ERK pathway ( A ) Clustering heatmap showing the expression profile of differentially expressed metabolism-related genes in host cells after treatment with MEK/ERK inhibitors Binimetinib (BI) and PD0325901 (PD). Red indicates upregulated genes, and blue indicates downregulated genes. ( B ) PPI network analysis of differentially expressed metabolism-related genes. Node size is positively correlated with the network centrality (Degree value) of the gene. Node color from dark purple to light purple represents centrality from high to low. ( C ) RT-qPCR detection of Fos-specific siRNA knockdown efficiency. ( D ) Western blot detection of the expression efficiency of HA-tagged Fos overexpression vector. Tubulin was used as the protein loading control. ( E ) RT-qPCR detection of the effects of Fos knockdown/overexpression on the transcription levels of six core metabolic genes. ( F ) RT-qPCR detection of the effects of Fos knockdown on the transcription levels of six core metabolic genes under ILTV infection conditions. ( G ) ChIP-qPCR detection of Fos binding to the promoter regions of six core metabolic genes, with isotype control IgG as the negative control. Data in ( C , E – G ) are expressed as mean ± SD. n = 3. * indicates statistically significant difference between groups ( p < 0.05). ns indicates no statistically significant difference.
