Notably miR-34c over -expression exacerbated Sipa1 down-regulation induced by DOX, while the transfection with mir-34c hairpin inhibitor significantly rescued the expression (Figure 5C), suggesting that miR-34c is mediating the DOX -induced regulation of Sipa1. [score:11]
The screening for putative targets of microRNAs in DOX treated animals, revealed that a number of DOX-responsive microRNAs may regulate mRNAs involved in cardiac tissue remo deling (data not shown), but we also speculated that the Sipa1 mRNA transcripts could be targeted by miR-34c directly. [score:7]
Ambra1 expression was induced by DOX treatment in vivo and miR-34c could control its endogenous expression levels in H9c2 cardiac myoblasts. [score:5]
Finally, to confirm whether the regulatory effect of miR-34c on the levels of Sipa1 mRNA was direct, 2 luciferase -based reporter expression vectors (pmiR-GLO-Sipa1 WT and mutated) were generated by cloning a 200 nucleotide region surrounding the predicted microRNA seed from each of their 3′-UTR regions downstream of a firefly luciferase reporter gene. [score:5]

Vice versa transfection of a miR-34c-directed hairpin inhibitor showed a statistically significant decrease of Ambra1 mRNA level. [score:4]
In our study miR-215, part of the miR-192/miR-215 cluster, and miR-34c, involved in DNA damage mediated proliferation arrest [36], [37], [38], [39], were up-regulated, consistent with the pharmacological effect of DOX. [score:4]
Comparable changes for many of these microRNAs were confirmed in additional animals, and a subset of five microRNAs (miR-208b, miR-215, miR-216b, miR-367 and miR-34c) and were largely unaffected by the direct Top2 inhibitor etoposide (EPS) (Figure 3). [score:4]
Finally, evidence for the direct targeting of Sipa1 mRNAs by miR-34c was provided for the first time, and this microRNA-mRNA interaction could potentially play a role in the molecular response to DOX in the rodent heart. [score:4]
However miR-215 and miR-34c were not significantly up-regulated by EPS administration, suggesting that this compound may not trigger a p53 response under these experimental conditions. [score:4]
Interestingly miR-215, up regulated by DOX in this study, was also linked to p53 mediated cell cycle arrest [37], [38], consistent with the pharmacology of DOX and partially replicating expression changes of miR-34c upon treatment, thus strengthening the biological relevance of our findings and consistency with previously published mechanisms [36]. [score:4]
Stratagene “Quick change” kit was used to introduce a 6 nt mutation in the miR-34c predicted seed site to generate the pmiR-GLO-Sipa1 mutant and the pmiR-GLO-Tnni3k mutant expression vectors. [score:4]
The transfection of miR-34c mimics in H9c2 showed a statistically significant decrease of Sipa1 mRNA, as the transfection of miR-34c hairpin inhibitor (HI) showed a statistically significant increase of Sipa1 mRNA (Figure 5C). [score:3]
Five of these microRNAs (miR-208b, miR-215, miR-216b, miR-34c and miR-367) displayed a consistent dose -dependent response to DOX at 2 and 4 weeks and were thus chosen as candidates for further expression profiling across the larger in vivo study treatment groups including co-treatment of DOX with DZR and treatment with EPS only (Figure 3). [score:3]
Therefore miR-34c is directly implicated in the DOX -induced modulation of Sipa1 mRNA regulation. [score:3]
Transfection with miR-34c mimic and inhibitor respectively exacerbated and rescued Sipa1 mRNA levels in H9c2 treated with DOX 0.1 and 1 µM overnight in comparison to negative controls. [score:3]

In fact, miR-34c over expression showed a statistically significant increase of the endogenous levels of Ambra1 mRNA (both with and without DOX). [score:3]
Transfection of miR-34c hairpin inhibitor showed a statistically significant decrease of Ambra1 mRNA. [score:3]

miR-34c directly controls DOX -induced Sipa1 mRNA decrease. [score:2]
This decrease was observed to a lower extent with other members of the miR-34 family (Figure 5C) suggesting that miR-34c interacted directly and specifically with the 3′-UTR of Sipa1. [score:2]
Reporter assay experiments further support that Sipa1 mRNA is a target of the miR-34 family, in particular miR-34c (Figure 5). [score:2]
In addition, our observations in H9c2 myoblast cell line suggest that miR-34c could be involved in the stimulation of the positive autophagy regulator Ambra1, also in presence of DOX. [score:2]

The co-transfection of the Sipa1 reporter with miR-34c in HEK 293 cells showed a significant decrease in the luciferase signal. [score:1]
Immunochemistry staining of autophagy markers like Ambra1 in heart tissues will also be required to elucidate the functional involvement of miR-215, miR-216b, miR-367, miR-208b and miR-34c in the DOX -induced autophagy process since they seem to be specifically associated to vacuoles appearance.

Other miRNAs from this paper: rno-mir-17-1, rno-mir-17-2
Therefore, we want to reveal whether the changes of CRFR1 expression occur with the accompanying changes in CRFR1 mRNA expression and miR-34c expression in the hypothalamus, as one of the miR-34c targets is the CRFR1 mRNA, which was regulated via the complementary site on its 3′UTR [15]. [score:10]
Our results demonstrated that severe traumatic stress in early adolescent induced lasting effects on anxiety-like behavior and spatial memory damage, different alterations of CRFR1 expression, and CRFR1 mRNA and miR-34c expression in hypothalamus between adolescent and adult period, which suggested that the miR-34c expression in hypothalamus may be unique regulator of stress reaction and may play a role in vulnerability to PTSD following exposure to traumatic experience. [score:8]
After a protracted struggle which did not work, the level of miR-34c expression returned to normal gradually, while the level of CRFR1 expression was upregulated, as we observed in the hypothalamus six weeks after foot shock. [score:8]
Second, we probe into the question whether miR-34c expression could timely regulate CRFR1 expression by using CRFR1 antagonist to block the CRFR1 activity. [score:6]
These results supported the idea that traumatic stress could induce increased miR-34c and decreased CRFR1 expression, which is consistent with the mechanism about miRNA influencing the protein translation [8]. [score:5]
miR-34c reduces the expression of stress-related proteins (such as CRFR1) and plays a role in the recovery process of stress reaction, suggesting that it might have vital implication in vulnerability to PTSD and might become a new target for the prevention and treatment of stress-related disorders [15]. [score:5]
However, miR-34c expression and the association between miR-34c and CRF1 expression in hypothalamus in adult rats after adolescent stress had not clarified. [score:5]

In this study, we focused on the short-term and long-term effects of adolescent foot shock on anxiety-like behavior, memory damage, protein CRFR1 expression, CRFR1 mRNA, and miR-34c levels in the hypothalamus of male Wistar rats. [score:3]
Combined with the result of improved behaviors in CRFR1 antagonist group, our study suggested that CRFR1 antagonist could target a positive process including increased level of miR-34c during acute stress reaction and give a new certification that miR-34c might be closely related with vulnerability to PTSD. [score:3]
The purpose of the study was first to detect dynamic changes, including short-term state and long-term state of miR-34c expression after early adolescent exposure to the stress. [score:3]
However, in the adult hypothalamus [F(2, 16) = 8.547, p = 0.003; see Figure 6], the S + A group exhibited higher miR-34c expressions than the CON group (p = 0.005) and S group (p = 0.012). [score:3]
The results indicated CRF1 antagonist might improve anxiety-like behavior and memory by alteration of miR-34c expression in hypothalamus. [score:3]
What caught our attention was that CRFR1 mRNA is the target of miR-34c. [score:3]
We would observe miR-34c expression in the hypothalamus after adolescent stress because this brain region is a complex region considered to be part of the limbic system and integrate the nervous system and the endocrine system and act as a “switching station” in the brain [19]. [score:2]
In consistent with our hypothesis, stressed rats showed lower level of CRFR1 mRNA, similar level of miR-34c, and increased CRFR1 expression compared with the unstressed rats. [score:2]
As a marker in stress recovery process, higher level of miR-34c was observed in S + A group. [score:1]
