Furthermore, we have also partly elucidated the molecular mechanisms that would explain the elevated circulating levels of glucose and NEFAs observed in the animals exposed to the short photoperiod, which were as follows: (1) a sharp down-regulation of the phosphorylated Akt2 levels in both soleus and gastrocnemius muscles; and (2) decreased expression in the soleus muscle of the glucose metabolism-related microRNA-194 and lower mRNA levels of the genes involved in glucose metabolism (Irs1, soleus, and Glut2, liver), β-oxidation (Had and Cpt1β, soleus) and fatty acid transport (Cd36, soleus and liver). [score:6]
Furthermore, the down-regulation of the soleus mRNA levels of the gene encoding IRS1, a key protein involved in the activation of Akt2 (Long et al., 2011); the lower levels of miR-194 observed in this tissue, which was also reported in insulin-resistant rats and in prediabetic and diabetic humans (Latouche et al., 2016); and the decreased hepatic gene expression levels of Glut2, the main glucose transporter in the liver (Lamia et al., 2008), could also account for the elevated serum glucose levels displayed by L6 rats. [score:6]
In addition, L6 rats presented lower mRNA levels of the insulin receptor substrate 1 (Irs1) (p = 0.007, Student’s t-test) (Figure 1A), a gene encoding a key protein involved in the insulin signaling pathway (Long et al., 2011), and lower expression levels of the glucose metabolism-related microRNA-194 (miR-194) (Latouche et al., 2016) than the L12 rats (p = 0.009, Student’s t-test) (Figure 3B).

Analysis of cellular miRNAs identified that administration of FGF2, FGF4 or INF-β significantly regulated the expression of several miRNAs (Fig. 7a) including the liver-enriched miR-194 31. miR-194 expression is regulated by hepatocyte nuclear factor 1α (HNF1-α 45) and its down-regulation may have an effect on cellular mobility 46. [score:10]
Microarray analysis identified a panel of miRNAs, which are either highly expressed in the heart (miR-1, miR-133a and miR-16) or in the liver (miR-122, miR-192 and miR-194) or invariant (miR-21; Supplementary Figure 1a). [score:3]
Total RNA from heart or liver were reverse transcribed according to the miQPCR and TaqMan protocols and the expression of 7 miRNAs (miR-1, miR-133b, miR-16, miR-122, miR-194 and miR-21) and a small nuclear RNA (RNU6) was measured by qPCR with respectively SYBR-Green (top panel) or TaqMan probes (lower panel).

In agreement, we showed that the expression of rno-miR-192, rno-miR-194, and rno-miR-499 was higher in the stone-forming group while their potential target gene chemokine receptor 2 (CCR2) was lower. [score:5]
Among these differentially expressed miRNAs, rno-miR-130b-3p, rno-miR-132-3p, rno-miR-181a-1-3p, rno-miR-222-3p, rno-miR-351-5p, and rno-miR-21-3p had the largest positive fold changes, while rno-miR-335, rno-miR-192-3p, rno-miR-194-5p, rno-miR-192-5p, rno-miR-499-5p, and rno-miR-210-3p had the largest negative fold changes (Table 1). [score:3]
Therefore, we proposed that, in the process of kidney stone formation, the overexpression of CCR2 mediated by relevant miRNAs, such as rno-miR-192, rno-miR-194, and rno-miR-499, would induce the inflammation and damage to the renal tubular epithelial cells and promote nephrolithiasis. [score:3]
Relative expression levels of the selected miRNAs and mRNAs were depicted in Figure 3. Consistent with the microarray data, real-time PCR confirmed that, compared with controls, rno-miR-132-3p, rno-miR-181a-1-3p, rno-miR-222-3p, and rno-miR-351-5p were significantly increased, while rno-miR-192-3p, rno-miR-194-5p, rno-miR-29c-3p, rno-miR-185-5p, and rno-miR-30c-5p were significantly decreased in stone-forming rat kidneys.

Of the nine miRNAs in this IRI-specific expression signature, six showed differential expression in our study (four of which exhibited increasing expression with age, including miR-21, miR-146a, miR-192, and miR-194) (Figure  6). [score:7]
The miRNAs that showed highest expression during middle or young adult ages (15 and 21 weeks) were miR-192 and miR-194 (Figure  6B,H), both of which show steady increase in expression at early ages, that peak at 15 and 21 weeks of age, before decreasing at older ages. [score:5]
For example, nine miRNAs (miR-21, miR-20a, miR-146a, miR-199a-3p, miR-214, miR-192, miR-187, miR-805, and miR-194) have been identified in C57BL/6 mice as promising biomarkers of kidney injury after renal ischemia reperfusion injury (IRI) [15]. [score:1]
