(B) Samples were collected at 6, 12, and 24 h post-infection with SQ2014 (MOI = 0.1), and the protein levels of PEDV-N and actin were detected by Western blot. (C) After 12 h of infection, the protein samples with different concentrations of DNJ were detected by Western blot. (D) Quantitative detection of PEDV S and N mRNA level by qRT-PCR. (E) The cells were collected 12 h after infection, and the virus titer of SQ2014 was detected by PFU. The means and standard deviations of three independent experimental replicates are shown. ** p < 0.01; *** p < 0.001.

(A) This section describes the comprehensive approach for infecting Vero-E6 cells and administering DNJ at a concentration of 100 µM. The treatment procedure is divided into three separate phases: pre-treatment, co-treatment, and post- treatment.

Figure Lengend Snippet: Figure 2. Drebrin contributes to actin cytoskeleton formation in cardiac myofibroblasts. A, MA plot of genes differentially expressed between siCtrl and siDbn1 myofibroblasts. At 72 h after siRNA transfection, the cardiac myofibroblasts were lysed and subjected to RNA-Seq, and the MA plots were drawn using the TPM values obtained. The x-axis represents the TPM value for gene expression, and the y-axis represents fold change between the two groups. The green plots indicate the genes downregulated on silencing Dbn1 (M < −1.0, A > 0), and the red plots indicate the genes in GO terms associated with focal adhesion and regulation of the actin cytoskeleton. B, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis of genes differentially expressed between the two groups. The genes downregulated on silencing Dbn1 (M < −1.0, A > 0) were analyzed using DAVID; the enriched KEGG pathways (gene count > 25) are shown.
