In contrast, three of the measured targets were significantly down-regulated during acute FMDV infection: bta-let-7 g (−1.96 fold decrease), bta-miR-1281 (−2.50 fold decrease), and bta-miR-26b (-3.09 fold decrease) (Table  2 and Fig.   2a). [score:4]
From these findings, it could be inferred that the induction of miR-17-5p in vivo might manipulate the cellular environment such that it favors FMDV replication, while miR-1281 is down-regulated due to an antagonistic effect. [score:4]
The strongest down-regulated miRNA, miR-1281, was also observed to have decreased levels in the serum collected from acutely infected cattle. [score:4]
Three miRNAs were significantly down-regulated in serum from persistently infected cattle: bta-miR-1281, bta-miR-181b, and bta-miR-23b-5p with fold decreases of 3.41, 2.77, and 2.44, respectively (Table  3). [score:4]
Of the miRNAs that were significantly up- or down-regulated, five were shared between acutely and persistently infected cattle (bta-miR-17-5p, bta-miR-144, bta-miR-497, bta-miR-22-5p, and bta-miR-1281). [score:4]
Of the miRNA species detected, miR-17-5p and miR-1281 were selected as they were among the 5 miRNA that showed similar differential expression in two different animal sets: acutely infected cattle (Table  2 and Fig.   2) and persistently infected cattle (Table  3 and Fig.   2). [score:3]
As with the bioinformatics analysis conducted to identify prospective gene targets for miR-17-5p and miR-1281, a consensus target gene for miR-455-3p was not found to further investigate (Additional file 2: Table S1). [score:3]
miR-17-5p was included in the second experimental set in panel b to confirm the non-effect seen in panel a In a separate experiment, we investigated the potential impact of one of the down-regulated miRNAs that was common to both acutely and persistently infected cattle, miR-1281, on the progression of FMDV infection in vitro. [score:2]

[score:2]
Mimics of miR-17-5p and miR-1281 were separately tested for their effect on FMDV replication in cell culture (Fig.   5). [score:1]
Also notable is that five of the detected miRNAs (bta-miR-1281, bta-miR-369-3p, bta-miR-26b, bta-miR-34a, and bta-miR-205) are involved in adipogenesis or other lipid metabolic pathways (Fig.   6b, green circle). [score:1]
The non-clustered miRNAs included: let-7 g, bta-miR-26b, bta-miR-150, bta-miR-34a, bta-miR-146a, bta-miR-147, bta-miR-205, bta-miR-455-3p, bta-miR-1224, bta-miR-1281, and bta-miR-31. [score:1]

While miR-17-5p had no apparent impact on the progression of FMDV infection, mimics of miR-1281 decreased the resulting FMDV titers by 2–3 logs. [score:1]
LFBK-αvβ6 cells were grown to approximately 30–40% confluence and transfected with mimics to miR-17-5p, miR-1281 (Thermo Scientific, Waltham, MA), a non-sense negative control miR (miR-NC), a control miR-342-5p that does not impact FMDV infection, or left untransfected following the RNAiMAX (Thermo Scientific, Waltham, MA) transfection method (manufacturer’s protocol). [score:1]
Eleven of the miRNAs are encoded in intergenic regions, including: bta-miR-1281, bta-miR-150, bta-miR-181b, bta-miR-497, bta-miR-144, bta-miR-34a, bta-miR-154a, bta-miR-146b, bta-miR-17-5p, bta-miR-205, and bta-miR-31. [score:1]
Given that miR-1281 mimics impede FMDV replication and the reported role of miR-1281 in cattle [50], it seems that the state of lipid homeostasis in the host plays an important role in the outcome of FMDV infection regardless of whether it is acute or persistent. [score:1]
As described for miR-17-5p above, mimic molecules of miR-1281 were transfected into LFBK-αvβ6 cells and 2 days post-transfection, the cells were infected with FMDV A24 Cruzeiro. [score:1]

There were no microRNAs regulated after 1 hour in culture, however after 4 hours in culture miR-491-3p, miR-34b, miR-595, miR-328 miR-1281 and miR-483-3p were significantly upregulated, with none being downregulated. [score:8]
However, after 4 hours in culture, significant upregulation was seen for miR-491-3p, miR-34b, miR-595, miR-328, miR-1281 and miR-483-3p, with no microRNAs being significantly downregulated. [score:7]

A total of 169 abundant miRNAs were detected in serum samples, and 3 differentially expressed miRNAs were identified: the expression of miR-1281 was significantly reduced at both acute and persistent infection stages; bta-miR-17-5p was expressed in the highest level at acute infection stage, whereas the expression level of bta-miR-31 was the highest during FMDV persistence.
