The proposed model of the mechanism of the dual actions of the host cell miRNA16a in restricting BCoV replication through targeting the BCoV-S glycoprotein and the host cell Furin and enhancing cytokine expression. ( A ) Schematic representation of the BCoV-Spike protein, highlighting the S1 and S2 subunits and Furin cleavage site (S1/S2). The miRNA16a targets two regions within the S1 subunit, indicated in red (starting positions 24,762 and 24,928). ( B ) A schematic diagram of the bovine Furin shows the miRNA16a target sites in the 3’UTR of the bovine host cell furin; red fonts indicate the starting nucleotides of the seed region of miRNA16a (starting position 793). ( C ) Illustration of the bovine cells transfected with miRNA scrambled (miRNA-Scr) followed by BCoV infection. The BCoV viral genome is released into the cytoplasm of infected cells, after which viral replication and the production of nested sets of sg mRNAs are initiated. BCoV infection markedly inhibited the expression of some host cytokines (IFN-α, IFN-β, IFN-γ, IL-6, and IL-10) but enhanced BCoV production. ( D ) A schematic illustration of the bovine cells transfected with miRNA16a followed by infection with BCoV. The miRNA16a targets host Furin at the cell surface, reducing the BCoV replication by abolishing the BCoV/S glycoprotein cleavage. The overexpression of miRNA16a also showed marked inhibition of the BCoV-S glycoprotein expression levels, ultimately reducing the production of other viral proteins, particularly BCoV-N. The miRNA16a, which targets BCoV-S and the host Furin, substantially inhibited the production of new BCoV progeny. Moreover, this targeting markedly increased the expression of some host cell cytokines, especially the (IFN-α, IFN-β, IFN-γ, IL-6, and IL-10), which led to further inhibition of BCoV progeny release.

( A ) Western blot analysis showed the expression of different EMT markers and furin in two cell lines (A549 and BEAs) after incubation with 5 μM RA at 24 h and 48 h. Hsc70 was used as a loading control. A representative image is shown (n = 3 independent cultures). ( B ) Localization of E-cadherin (green), detected by immunofluorescence staining in A549 and BEA cells after 5 μM RA treatment for 24 h. Zoom has been made around the dotted lines and magnified images are shown on the right side. ( C ) Representative IF analysis of furin (green) in lung cell lines (A549 and BEAs) after 24 h of RA incubation (5 μM). In both ( B , C ), nuclei were stained with DAPI and F-actin with phalloidin (cyan blue). Scale bars 20 μM and 60 μM for zoom images in ( B ).

RARα ChIP assay on furin promoter. ( A ) Potential binding sites for RAR and/or RXR nuclear receptors in the furine promoter region. CTF1, CTF2, and Enhancer (ENH) indicate 3 regions where most transcriptional factor binding sites that modulate gene transcription are concentrated. ( B ) ChIP data analysis of RARα binding to furin and MMP-9 genes in control rats (RA−) and control rats injected intraperitoneally with retinoic acid (RA+) (left panel, CONTROL group). The same analysis was carried out in vitamin A-deficient rats (RA−) and vitamin A-deficient rats injected intraperitoneally with retinoic acid (RA+) (Right panel, VAD). Chromatin was immunoprecipitated with an anti-RARα antibody (black bars) or a nonrelated antibody anti-IgG as a negative control (grey bars). Data are the result of three independent experiments and bars represent mean ± SD.

Figure 10. Proteomics analysis of the effects of the FURIN gene status on cytokine secretion under basal and LPS-stimulated conditions. Cytokine secretion was assessed on antibody arrays and quantified after normalization via background subtraction and scaling. The plot is divided into five panels representing key cytokine secretion patterns observed in response to LPS stimulation and FURIN gene status (WT, HZ, NZ): Top5 WTvsNZ (Cnt, LPS), top five cytokines showing significant changes in secretion between WT and NZ samples under both basal and LPS stimulation; Top5 HZvsNZ (Cnt, LPS), cytokines showing significant secretion differences between HZ and NZ clones under both basal and LPS stimulation; Top5 LPS effect (Furin independent), top five cytokines showing significant secretion effects upon LPS stimulation, regardless of the FURIN gene status; Top5 WT:LPS intxn, top five cytokines showing significant interaction effects between WT and LPS stimulation; Top5 HZ:LPS intxn, top five cytokines with significant interaction effects between HZ and LPS stimulation. Cytokine names are indicated at the top of each subplot. Bars are color-coded by a combined identifier containing the FURIN gene status and LPS stimulation status. The x-axis lists the combined identifiers, and the y-axis indicates the normalized cytokine secretion levels (results are averaged over duplicates).
