As examples, the liver-specific miR-122 promotes the replication of hepatitis C virus (HCV) [17], [18], while miR-196, miR-199, miR-296, miR-351, miR-431 and miR-448 inhibit HCV genome propagation [19], [20]; miR-32 effectively restricts the accumulation of primate foamy virus type 1 (PFV-1) in human cells [21]; miR-323, miR-491 and miR-654 inhibit the replication of the H1N1 influenza A virus by binding to the viral PB1 gene [22]; miR-28, miR-125b, miR-150, miR-223 and miR-382 target the 3′ end of human immunodeficiency virus (HIV) mRNA, thereby restricting HIV production [23]; miR-199a-3p and miR-210 limit the hepatitis B virus (HBV) surface antigen and polymerase production by degrading and/or inhibiting translation of viral mRNAs encoding these proteins [24]; overexpression of miR-24 and miR-93 suppresses vesicular stomatitis virus (VSV) replication through targeting the viral genes encoding RNA -dependent RNA polymerase (L protein) and phosphoprotein (P protein), respectively [25]; in macrophages, upregulation of miR-155 suppresses VSV replication, while inhibition of miR-155 had the opposite effect.

Of note, in addition to acting on κB-Ras2, miR-125b is also predicted (by TargetScan, miRanda and PicTar) to target a number of cellular mRNAs encoding proteins involved in apoptosis and inflammation processes, such as NAIF1 (nuclear apoptosis inducing factor 1), BAK1 (BCL2-antagonist/killer 1), RIT1 (Ras-like without CAAX 1), KSR2 (kinase suppressor of Ras 2), BCL2L12 (BCL2-like 12), and IRF4 (IFN regulatory factor 4), several of which have been validated as miR-125b targets recently [48], [51]– [56]. [score:10]
We found that overexpression of miR-125b stabilized κB-Ras2 mRNA and down-regulated of NF-κB activation in MARC-145 cells (Figure 5), and that pharmacological inhibition of NF-κB impaired PRRSV replication (Figure 6). [score:8]
When we were making efforts to choose potential cellular targets of miR-125b for further study, Murphy et al. reported that miR-125b negatively regulates NF-κB by stabilizing the mRNA encoding κB-Ras2 (NF-κB inhibitor interacting Ras-like 2), a key inhibitor of NF-κB signaling [48]. [score:8]
Because miR-125b does not target directly the PRRSV genome or affect cellular interferon responses, we next reasoned that miR-125b might target other proviral cellular factor(s) to reduce PRRSV replication. [score:6]

Interestingly, we found that PRRSV infection down-regulated the expression of miR-125b as the infection progressed. [score:6]

It is plausible to speculate that PRRSV infection gradually decreases miR-125b mRNA expression, which, in turn, relieves the stabilizing effect on κB-Ras2 mRNA, ultimately leading to subsequent NF-κB activation. [score:3]
Conversely, transfection of the miR-125b inhibitor significantly augmented PRRSV -induced NF-κB (Figure 5E). [score:3]
No appreciable effect of either the mimic or inhibitor of miR-125b (at up to 120 nM) on cellular viability and morphology could be observed (data not shown). [score:3]

[score:2]
If miR-125b reduces PRRSV replication by down -regulating NF-κB, activation of NF-κB should promote PRRSV replication. [score:2]

The pMIR-REPORT luciferase reporter vector (Ambion) was used as the cloning vector for reporter gene assay analyzing the potential target region of miR-125b in PRRSV genome. [score:2]
Based on the results above and those from previous studies [49], [50], it appears that PRRSV infection induces NF-κB activation, which facilitates PRRSV replication, while miR-125b negatively regulates NF-κB signaling, thereby reducing PRRSV replication. [score:2]
Therefore, we propose a working mo del in which miR-125b negatively regulates NF-κB, thereby reducing PRRSV replication (Figure7). [score:2]

In addition to the best-studied myomiRs (miR-1, -206 and miR-133 families), 11 other DE muscle-related miRNAs (miR-378 [24], miR-148a [27], miR-26a [28, 29], miR-27a/b [30, 31], miR-23a [32, 33], miR-125b [34], miR-24 [35], miR-128 [36], miR-199a [37] and miR-424 [38]) with high abundance (average RPM >1,000) and another 14 (miR-181a/b/c/d-5p [26], miR-499-5p [11], miR-503 [38], miR-486 [39], miR-214 [40], miR-29a/b/c [41– 43], miR-221/222 [44] and miR-208 [11] with low abundance (average RPM <1,000) were detected in myogenesis of pig. [score:1]
However, Cluster 5 illustrated that ssc-miR-206 and other four muscle-related miRNAs (ssc-miR-126, -148a/b and -15b) continued to decline while ssc-miR-133b and eleven other muscle-related miRNAs (ssc-miR-125b, -128,-181a/b, -199a, -214, -23a, -24, -424, -503 and -7) in Cluster 4 presented a down and then up trend from 77 dpc to 180 dpn, suggesting their different roles played in adult fiber maturation.
