Finally, based on the cellular mechanisms of miRNAs, which is the regulation of gene expression by the sequence-selective targeting of mRNA leading to their cleavage or a reduction in translational efficiency, we checked the protein expression level of PVRL1 by a WB assay and also found that PVRL1 protein expression was sharply declined in 293T cells transfected with the miR-4516-up plasmid (Figure 4D). [score:11]
The protein expression levels were slightly and dramatically decreased in EV-A71- and CV-A16-infected cells (P < 0.05), respectively, whereas the protein expression levels were remarkably decreased with miR-4516-overexpression pretreatment in an EV-A71 infection and apparently recovered with a miR-4516-knockdown pretreatment in a CV-A16 infection (P < 0.05). [score:8]
Among these miRNAs, miR-4516, which was down-regulated in EV-A71 infection and up-regulated in CV-A16 infection, presented the most significant change (Figure 4A). [score:7]
Our WB and IF observations showed that nectin1 was slightly lower and miR-4516 was down-regulated in EV-A71-infected cells, while nectin1 was notably lower and miR-4516 was up-regulated in CV-A16-infected cells, but these alterations of nectin1 were completely reversed in EV-A71- and CV-A16-infected cells pretreated with the miR-4516-up and miR-4516-down plasmids, respectively. [score:7]
miRNA -negative control (NC) plasmid, miR-4516-overexpression plasmid, 3′-UTR NC plasmid, PVRL1 3′-UTR plasmid, PVRL1 3′UTR-Mutant plasmid and TRAF6 3′-UTR plasmid (which was demonstrated that it was a direct target of miR-4516) used in this study were synthesized by the Shanghai Genechem Co.

Figure 6Junctional proteins expression in 16HBE cells infected with EV-A71 or EV-A71 pre -treated with a miR-4516-overexpression plasmid, and CV-A16, or CV-A16 pre -treated with a miR-4516-knockdown plasmid. [score:6]
In the present study, based on results from our previous study, we screened the miR-4516 and its target PVRL1 (also known as nectin1) which might be the key regulators contributed to the different impairments of the epithelial barrier because of their opposite expression pattern during EV-A71 and CV-A16 infections. [score:6]
Collectively, we proposed that differentially expressed miR-4516 induced by EV-A71 and CV-A16 infections might lead to the disruption of cellular junctions by targeting nectin1, which ultimately resulted in perturbation of barrier functions of 16HBE cells. [score:5]
Furthermore, the expression level of PVRL1, a predicted target of miR-4516, was remarkably increased in EV-A71 infection and markedly decreased in CV-A16 infection (Figure 4B). [score:5]
PVRL1-3′UTR is the direct target of miR-4516 which was the key miRNA involved in regulation of epithelial barrier function. [score:5]
Transfection with the miR-4516-overexpression plasmid resulted in a significant reduction of PVRL1 protein expression in 16HBE cells. [score:5]
Therefore, these observations indicated that EV-A71 and CV-A16 could interfere with AJ and TJ assembly, which was intimately linked to the breakdown of the epithelial barrier, and miR-4516 was differentially expressed following infection with EV-A71 or CV-A16, which might be important regulators involved in the degradation of AJ- and TJ-related proteins. [score:4]
In contrast, in EV-A71 infected cells that overexpressed miR-4516, most showed a substantial reduction or even the disappearance of the nectin1 staining, while in CV-A16 infected miR-4516-knockdown cells, we observed stronger nectin1 staining at the cell-cell contact sites. [score:4]
In conclusion, for the first time, this study demonstrated that miR-4516 regulated the epithelial permeability barrier functions by targeting PVRL1 and might contribute to the differences in the pathogenesis of EV-A71 and CV-A16 infections. [score:4]
Figure 4PVRL1 was speculated as the direct target of miR-4516. [score:4]
Therefore, it was confirmed that PVRL1 3′-UTR was the direct target of miR-4516. [score:4]
It is noteworthy that EV-A71 and CV-A16 both actually broke the epithelial barrier, but comparatively, an opposite miR-4516 expression pattern resulted from EV-A71 and CV-A16 infection in 16HBE cells, which might regulate cell-cell TJs and AJs and consequently cause different degrees of impairment of the epithelial barrier that further facilitate viral infection, especially CV-A16 infection. [score:4]

It has been reported that high expression levels of miR-4516 were associated with the infiltrative growth of the follicular variant of papillary thyroid carcinomas (Borrelli et al., 2017), but its role in EV-A71 and CV-A16 infections remains unclear. [score:3]
The saffron arrows indicate that CV-A16-infected cells pre -treated with the miR-4516-knockdown plasmid show less recovery of these proteins. [score:2]
Additionally, the regulation mechanism of miR-4516 on PVRL1 was further detected by WB in 293T cells subjected to miR-4516-up transfection. [score:2]
