Conversely, inhibition of mTORC1 signaling resulted in up-regulation of miR-29 expression and suppressed MCL-1 expression in cardiomyocytes. [score:12]
Moreover, since DM is associated with either insulin deficiency or a lack of insulin signaling, we also posited that insulin would suppress the expression of the miR-29 family in cardiomyocytes and up-regulate MCL-1 expression. [score:10]
Data presented here shows that insulin down-regulates the expression of diabetic marker miR-29 family miRNAs in mouse cardiomyocytes and preserves the expression of cardioprotective MCL-1. Consistent with this insulin effect, 11-week old hyperinsulinemic ZDF rats only had a mild loss of MCL-1 expression and did not show any damage in myocardium. [score:10]
Conversely, inhibition of mTORC1 signaling by Rap or inhibitors of mTORC1 substrates significantly increased expression of miR-29 family miRNAs and suppressed cardioprotective MCL-1 in mouse cardiomyocytes. [score:9]
Since MCL-1 is a target of miR-29 family miRNAs, and Rap treatment increases miR-29 expression, we investigated whether a miR-29 inhibitor cocktail (inhibitors of miR-29a, b and c) would improve MCL-1 expression in Rap treated HL-1 cells. [score:9]
Since miR-29 suppresses MCL-1 and the miR-29 family miRNAs are elevated in DM we hypothesized that one of the mechanisms by which DM promotes heart disease is by causing dysregulation of the miR-29-MCL-1 axis and suppressing MCL-1 levels in cardiomyocytes that can lead to cardiomyocyte disorganization. [score:8]
B) Expression of miR-29 family miRNAs (miR-29a, b and c) in mouse cardiomyocyte HL-1 cells is suppressed by treatment with INS (100 nM; 12 h) and up-regulated by treatment with Rap (10 nM; 12 h). [score:8]
Transfection of HL-1 cells with miR-29 inhibitor cocktail reversed Rap -mediated suppression of MCL-1 expression. [score:7]
analysis using anti-MCL-1 antibody showed that Rap treatment substantially suppressed MCL-1 expression in HL-1 cells transfected with Allstars negative control siRNA, but not in HL-1 cells transfected with miR-29 inhibitor cocktail (Fig. 2D). [score:7]
We have shown in vitro that a miR-29 inhibitor cocktail could reverse Rap -mediated suppression of MCL-1 protein expression in cardiomyocytes. [score:7]
Since increased expression of different members of miR-29 family is associated with DM, we tested the effects of insulin that attenuates the progression of DM, and rapamycin (Rap) that promotes the progression of DM, on the expression of miR-29 family miRNAs in HL-1 cells. [score:5]
We undertook this study to uncover the role of microRNA miR-29 family and its target MCL-1, a pro-survival molecule that is critical for cardiomyocyte survival under stress, in the myocardium damage seen in diabetic heart disease. [score:5]
However, suppression of hyperinsulinemia by Rap in the absence of regulation of hyperglycemia as seen in Rap -treated ZDF rat promotes severe dysregulation of cardiac miR-29-MCL-1 axis that leads to disruption and loss of myofibril bundle organization. [score:5]
This would have led to the up-regulation of all miR-29 family miRNAs in their heart tissues that resulted in the severely dysregulated miR-29-MCL-1 axis in Rap -treated ZDF rats. [score:5]
Since Rap-treatment increased miR-29 levels and suppressed MCL-1 mRNA levels in mouse HL-1 cardiomyocytes, we tested whether Rap-treatment would increase cardiac miR-29 family miRNAs and suppress cardiac MCL-1 mRNA even further in young ZDF rats. [score:5]
Further studies are needed to also confirm that in in vivo rodent mo dels a miR-29 inhibitor cocktail would improve cardiac MCL-1 protein expression. [score:5]
Insulin treatment strongly suppressed miR-29a, b and c in cardiomyocytes whereas Rap treatment significantly enhanced expression levels of all three miR-29 family members in HL-1 cardiomyocytes (Fig. 1B). [score:5]
20 nM of miR-29 inhibitor cocktail (mirVana miRNA inhibitors for miR-29a, b and c) or 20 nM Allstars negative siRNA (Qiagen) was used for transfection. [score:5]
Though rapamycin has well-established cardioprotective effects, an additional increase in miR-29 family miRNAs due to mTORC1 inhibition in the heart tissues of DM patients can potentially suppress MCL-1 and exacerbate cardiomyocyte disorganization and cardiac damage. [score:5]
D) staining with anti-MCL-1 antibody and nuclear stain DAPI in HL-1 cells transfected with either (a) Allstars negative siRNA and (b) Allstars negative siRNA and treated with Rap (10 nM), or (c) miR-29 inhibitor cocktail (mirVana miRNA inhibitors for miR-29a, b and c) and treated with Rap (10 nM). [score:5]
Since insulin suppressed miR-29 in HL-1 cardiomyocytes, we posited that insulin would improve expression of MCL-1 in these cells. [score:5]
In brief, the suppression of miR-29 expression by insulin could be a previously unidentified cardioprotective mechanism in hyperglycemia. [score:5]
Regulation of miR-29 target MCL-1 by insulin and rapamycin in mouse cardiomyocytes. [score:4]
This observation implied that miR-29 family miRNAs regulate MCL-1expression in HL-1 cardiomyocytes. [score:4]
Though 11-week old ZDF rats had a mild dysregulation of miR-29-MCL-1 axis that resulted in about 45% suppression of MCL-1, no visible differences were observed in the histopathology of the RV tissues between ZL and ZDF rats. [score:4]
These data suggested that a miR-29-MCL-1 axis, similar to that seen in mouse and human pancreatic β-cells [15] exists in mouse cardiomyocytes and it is regulated by insulin and rapamycin, an mTORC1 inhibitor. [score:4]
We only observed a mild dysregulation of miR-29–MCL-1 axis at this stage and a 45% suppression of MCL-1 mRNA (Figs. 3I and 3J). [score:4]
Additionally, knock-down of miR-29c suppressed high glucose induced apoptosis of podocytes and improved kidney function [9]. [score:4]
Therefore, dysregulation of miR-29-MCL-1 axis caused by loss of insulin and mTORC1 inhibition is a major factor in promoting myocardial damage in DM in ZDF rats. [score:4]
Collectively, our data shows the steps in the dysregulation of miR-29-MCL-1 axis in heart tissues during the progression of DM as shown in Fig. 6. Briefly, at the age of 11 weeks, healthy ZL rats show basal level expression of miR-29 and MCL-1 and their myocardium is well organized. [score:4]
miR-29 family miRNA expression pattern. [score:3]
Since we observed that insulin could suppress miR-29 family miRNAs in cardiomyocyte HL-1 cells, it is conceivable that the lack of significant increase in miR-29c in the myocardium of 11-week old ZDF rats despite severe hyperglycemia could be due to their compensatory hyperinsulinemia (a 14-fold increase in plasma insulin). [score:3]
RAP for miR-29 a, b, and c. The role of the miR-29-MCL-1 axis in the progression of DM -associated heart disease is not known. [score:3]
Expression of all three miR-29 family miRNAs (a, b and c) were significantly higher (at least 2 fold for each miRNA) in ZDF myocardium. [score:3]
Though insulin treatment could induce phosphorylation of S6K1 rapidly, in this study we chose a 12 hr treatment to be consistent with the treatment time used for determining the changes in miR-29 and an MCL-1 mRNA expression in response to insulin in HL-1 cells. [score:3]
Cardiac tissues of 15-week old Rap treated ZDF-rats (Rap treatment from 9-weeks to 15-weeks) displayed a ∼2-fold increase in miR-29 family miRNAs and a 4-fold suppression of MCL-1 mRNA. [score:3]
Since insulin is an activator of the nutrient sensor kinase mammalian target of rapamycin complex 1 (mTORC1), we further posited that mTORC1-signaling mediates insulin's effects on miR-29-MCL-1 axis. [score:3]
However, qRT-PCR showed that Rap treated ZDF rats had at least a 2-fold increase in the expression of all miR-29 family members (miR-29a, b and c) (Fig. 4E). [score:3]
This observation may have important clinical relevance given the fact that patients with DM are reported to have an increase in miR-29 expression [8], [44]. [score:3]
Increased expression of diabetic marker miR-29 family miRNAs is seen in rodent mo dels of DM and in young and adult diabetic patients with T1DM or T2DM. [score:3]
Expression of miR-29a and b were significantly higher in the myocardium of ZDF rat, but miR-29c was not significantly different between ZL and ZDF myocardium. [score:3]
Therefore, we conclude that regulation of miR-29-MCL-1 axis by insulin is a cardioprotective mechanism and compensatory hyperinsulinemia in conditions of hyperglycemia would regulate miR-29-MCL-1 axis in diabetic heart and prevent significant myocardial damage in young (11- and 15-week) ZDF rats. [score:3]
Suppression of miR-29 by anti-miR-29 oligomers protects against myocardial ischemia-reperfusion injury, abdominal aortic aneurism and diabetic nephropathy [9]– [13]. [score:3]

Based on the data presented here, we contend that the normal functioning of miR-29-MCL-1 axis is an important cardioprotective mechanism regulated by insulin that exists in female mouse atrial cardiomyocytes and male ZDF rat heart tissue. [score:2]
In contrast Rap -treated ZDF rats have very low INS, severe hyperglycemia, and severe dysregulation of miR-29-MCL-1 axis. [score:2]
These data suggest that cardiac miR-29-MCL-1 axis is mildly dysregulated in 11-week old ZDF rats that suffer from DM. [score:2]

To our knowledge this is the first report that shows insulin is a regulator of miR-29 family miRNAs. [score:2]
For this study, we focused on the RV of ZDF rat heart since RV dysfunction from structural and functional perspectives has been described previously in young ZDF rats [5], [6] and therefore the baseline parameters were easy to compare in the context of regulation of the miR-29-MCL-1 axis. [score:2]
Our in vitro studies on mouse cardiomyocyte HL-1 cells showed that insulin regulates miR-29 family miRNAs (mir-29a, b and c) and improves cardioprotective MCL-1 levels in cardiomyocytes. [score:2]
Mild dysregulation of cardiac miR-29-MCL-1 axis in a hyperinsulinemic DM background (ZDF rat) does not show significant cardiac myofibril disorganization or loss. [score:2]
These observations suggest that Rap treatment causes severe dysregulation of the miR-29-MCL-1 axis in cardiac tissues of ZDF rat. [score:2]
Moreover, Rap treatment of young hyperinsulinemic ZDF rats caused severe dysregulation of cardiac miR-29-MCL-1 axis and myofibril bundle disorganization indicative of myocardial damage. [score:2]
These observations suggest that the myocardium of Rap -treated ZDF rats that had a further increase in miR-29 a, b and c miRNAs and further suppression of MCL-1 (Fig. 4E and 4F) compared to age-matched control rats, exhibited significant disorganization of myofibril bundles that reflect tissue damage.

Thus, the miR-29-MCL-1 axis is a major contributor to pancreatic dysfunction and T1DM. [score:1]
In diabetic mice, an increase in miR-29c was associated with podocyte cell death that underlies diabetic nephropathy. [score:1]
In this context, the diabetic marker microRNA miR-29 family that plays a role in increasing cell death is particularly noteworthy. [score:1]

To determine how DM progression (natural or advanced by Rap treatment) caused dysregulation of cardiac miR-29-MCL-1 axis and promoted cardiomyocyte disorganization, we used male ZDF rats, a well-established rodent mo del for advanced DM [5], [6], [26], [27] and evaluated the correlation between regulation of miR-29-MCL-1 axis and disorganization of myofibril bundles in cardiac right ventricle. [score:1]
miR-29 is also one of the several miRNAs associated with inflammatory microvesicles [14]. [score:1]
Hyperglycemia is known to significantly increase miR-29c [9]. [score:1]
In this study we used mouse atrial cardiomyocyte HL-1 cells and right ventricular tissues of ZDF rats to investigate how Rap modulates expression of miR-29-MCL-1 axis. [score:1]
The miR-29 family consists of miR-29 a, b (b1 and b2) and c that are located on two different chromosomes (chromosomes 4 and 13 in rat, 1 and 6 in mouse and 1and 7 in human) [7]. [score:1]
Further studies with primary cultures of cardiomyocytes from rat atrium and ventricle are needed to confirm that INS -mediated modulation of miR-29-MCL-1 axis is similar in atrial and ventricular cells. [score:1]
This study was undertaken to investigate whether insulin regulated the miR-29-MCL-1 axis in cardiomyocytes and if conditions that lead to progressive loss of insulin promote dysregulation of cardiac miR-29-MCL-1 axis and disorganization of cardiomyocytes. [score:1]

Taken together, the present study shows that bladder outlet obstruction, such as that seen in elderly men with enlarged prostate glands, leads to reduced expression of miR-29b and miR-29c in the bladder and that this is associated with increased expression of miR-29 targets, including the matrix proteins elastin and Sparc. [score:7]
Expression of all six of these targets peaked at the nadir of miR-29c expression (compare Figure 3B with Figure 2A), and they declined sharply on de-obstruction when the miR-29c level recovered. [score:7]
Human detrusor cells were transfected with miR-29c inhibitor and eight validated miR-29 targets, most of which were represented among the top 50 predicted targets in Figure 3A, were examined using western blotting. [score:7]
We also demonstrate that genetic depletion of miRNAs, including miR-29, increases bladder elastin expression and stiffness independently of outlet obstruction and that miR-29 inhibitor transfection in vitro replicates several of the expression changes associated with miR-29 repression in outlet obstruction. [score:7]
Together, these circumstances may well explain the more widespread apparent impact of miR-29 repression in outlet obstruction (8/8 examined target proteins increased) compared to inhibitor transfection (4/8 examined target proteins increased). [score:6]
Four of the eight selected miR-29 targets, including Eln (elastin or tropoelastin), Fos (also known as c-Fos), Sparc (osteonectin) and sprouty homolog 1 (Spry1), were significantly increased following inhibitor transfection (Figure 3D, left row). [score:5]
For tropoelastin, whose mRNA correlated inversely and significantly with miR-29 in outlet obstruction, we found that transfection of a miR-29c inhibitor resulted in increased tropoelastin expression. [score:5]
To address the functional impact of miR-29, we transfected a miR-29 inhibitor and mimic in vitro and conditionally deleted Dicer in vivo [5] and examined the effect of these interventions on tropoelastin expression and on tissue mechanical properties. [score:5]
Currently, we can only speculate on the role of these proteins in outlet obstruction, but it is of considerable interest that the miR-29 target Spry1 [14], which is an established ERK1/2 inhibitor [49], increases after prolonged outlet obstruction. [score:5]
Of the 30 miRNAs that are highly expressed in the mouse detrusor [5, 41] none except miR-29 is predicted to target tropoelastin. [score:5]
For miR-29c inhibitor and mimic experiments, cells were transfected with miR-29c inhibitor (Thermo Scientific, Pittsburgh, PA, USA; 20nM), mimic (Mission miRNA: Sigma-Aldrich, St. [score:5]
Some predicted and confirmed miR-29 targets, including Fbn1, which is an integral part of the elastic fiber meshwork, and Lamc1, a protein present in the basement membrane, were increased in outlet obstruction but were not significantly affected at the protein level following inhibitor transfection (not shown). [score:5]
Additional regulatory inputs on miR-29 expression include c-Myc and NF-κB [11], and recent work has provided considerable insight into c-Myc -mediated repression, which appears to depend on a repressor complex consisting of c-Myc, histone deacetylae 3 (Hdac3) and enhancer of zeste homologue 2 (Ezh2) [18]. [score:4]
Detrusors from smooth muscle-specific Dicer knockout mice were used to examine if reduction of miR-29 in vivo increases tropoelastin expression. [score:4]
We found that Dicer knockout reduced miR-29b and miR-29c by about half and increased tropoelastin expression. [score:4]
Sparc, Spry and Fos were similarly reciprocally regulated by miR-29c inhibitor and mimic, and increased in outlet obstruction. [score:4]

This revealed a pronounced increase around individual cells and around muscle bundles in obstructed bladders, consistent with its increased mRNA level and with the fact that it is a miR-29 target [48]. [score:3]

Time courses of expression for miR-29c and miR-29b from the microarray experiment are depicted in Figure 2A and 2B. [score:3]
A previous microarray study [31] with close to genome-wide coverage showed that overexpression of miR-29c reduced six mRNAs: Col4a1; Fbn1; Lamc1; collagen, type XV, α1 (Col15A1); thymine-DNA glycosylase (Tdg); and collagen, type III, α1 (Col3A1). [score:3]

Repression of miR-29 during outlet obstruction is associated with increased levels of miR-29 target messenger RNAs (mRNAs). [score:3]
The matricellular protein Sparc is a confirmed miR-29 target [13] that influences collagen fibril morphology and function [47]. [score:3]
We also predicted the free energies of miR-29c binding to proximal sites in the Eln and Sparc 3’UTRs and found them to be within the range of authentic miRNA-target pairs (Figure S1A, B). [score:3]
Bladder outlet obstruction increases miR-29 target protein levels. [score:3]
Type I and type III collagens are however established targets of miR-29 [10], and their mRNAs were largely unchanged at 10 days and at 6 weeks (Col1a1 at 10 days: up by 15%, q=2.7, p=0.05; Col3a1 at 10 days: up by 12%, q=8.7, p=0.12). [score:3]
Unlike other miRNAs, miR-29 also targets a large battery of collagens, including collagens I and III [10]. [score:3]
This would repress miR-29, and hence it would be more difficult to see an effect of miR-29 inhibition. [score:3]
Our studies support a mo del in which multiple signaling pathways converge on repression of miR-29 in outlet obstruction, facilitating matrix protein expression and leading to altered mechanical properties of the urinary bladder. [score:3]
Real-time quantitative PCR for miR-29c and miR-29b (Figure 2C and D) confirmed reduced expression of both miRNAs at 10 days. [score:3]
MiR-29 target mRNAs change in outlet obstruction. [score:2]
Thus, several independent lines of evidence support a regulatory role of miR-29 in tropoelastin synthesis in the bladder, consistent with the large number of miR-29 binding sites in its mRNA [10, 12]. [score:2]

The reduced level of miR-29 leads to increased levels of mRNAs encoding extracellular matrix proteins (3), including elastin and Sparc (osteonectin), but possibly also collagens and fibrillin-1. The resulting protein synthesis and matrix deposition (4) leads to increased detrusor stiffness (5) (and increased elastic modulus) which counteracts (6) further distension. [score:1]
Together, these findings support the view that repression of miR-29, independent of surgical obstruction of the urethra, leads to matrix remo deling. [score:1]
We therefore hypothesized that outlet obstruction leads to SMAD3 phosphorylation repressing miR-29, and that this in turn has an impact on protein synthesis and mechanical properties of the bladder. [score:1]

The miR-29 cluster has gained recognition as a modulator of extracellular matrix production [7- 10]. [score:1]
This hypothesis was based on a handful of prior studies demonstrating increased mRNA levels for different TGF-β isoforms shortly after outlet obstruction (e. g. 24), and on the documented repression of miR-29 by TGF-β/SMAD3 [11]. [score:1]
Thus we measured the eight validated miR-29 target proteins (the same ones measured after inhibitor transfection) at 6 weeks of obstruction. [score:1]
c-Myc and NF-κB are also known to repress miR-29 [11, 18], and both pathways have previously been shown to be activated in outlet obstruction and by mechanical distension [37- 39]. [score:1]
The proposed mo del fits the data presented in this article, but alternative interpretations are possible and steps upstream of miR-29 repression need in vivo corroboration. [score:1]
This supported the possibility that c-Myc and NF-κB, but not SMAD3, might be involved in the repression of miR-29b and miR-29c at 10 days. [score:1]
SMAD3 activation, which is known to be involved in TGF-β -mediated repression of miR-29, was not significantly increased at 10 days when miR-29b and miR-29c appeared to be maximally repressed. [score:1]
Our findings do not provide any further guidance as to which possibility is correct, but they do indicate that SMAD3, which is specific for the miR-29b2/c gene [11], may be involved in chronic repression of miR-29c, but not in its acute reduction. [score:1]
c-Myc -mediated repression of miR-29 involves a complex consisting of c-Myc (Myc), histone deacetylase 3 (Hdac3) and enhancer of zeste homolog 2 (Ezh2) which binds to conserved sequences in the promoters of the miR-29a/b1 and miR-29b2/c genes [18]. [score:1]
MiR-29 -mediated extracellular matrix remo deling has been demonstrated in the infarcted heart [10] and during aortic aneurysm progression [7- 9], but miR-29 also plays roles in cell proliferation, muscle differentiation and apoptosis [11]. [score:1]
It comprises three miRNAs (miR-29a, miR-29b, and miR-29c) derived from two independent genes [10]. [score:1]
Therefore, reduction of miR-29b and miR-29c could well promote collagen production at an unchanged mRNA level at these times. [score:1]
This in turn (2) activates multiple signaling pathways including c-Myc, NF-κB and TGF-β/SMAD3 that in turn repress miR-29. [score:1]
With the possible exception for tropoelastin, transfection of miR-29c mimic was associated with a reduction of these proteins (Figure 3D, right row). [score:1]
Added to the correlation between miR-29c and Col4a1 mRNA this favors a causal relationship between the repression of miR-29 and the increase of Col4a1 in outlet obstruction. [score:1]
Combined, these findings provide support for our hypothesis that miR-29 reduction contributes to increased protein synthesis in the bladder following outlet obstruction and that this in turn influences matrix properties and stiffness (Figure S2). [score:1]
We hypothesized that miR-29 repression may contribute to increased detrusor stiffness in outlet obstruction. [score:1]
We propose that bladder distension leads to repression of miR-29 via three distinct mechanisms and that this has an impact on tropoelastin and Sparc synthesis and on tissue mechanical properties. [score:1]
To address this hypothesis we examined if SMAD proteins are phosphorylated and whether miR-29 is reduced in outlet obstruction. [score:1]
Right row in D shows effect of miR-29c mimic. [score:1]
Eln correlated significantly with miR-29c (Figure 3E) and with the mean of miR-29b and miR-29c (not shown). [score:1]
De-repression of Sparc may thus also contribute to a miR-29 -mediated change of detrusor stiffness in outlet obstruction. [score:1]
Our lack of evidence for SMAD2/3 activation at 10 days, when miR-29b and miR-29c appeared maximally repressed, forced us to consider alternative mechanisms. [score:1]
In view of this outcome we tested if Eln and Sparc mRNAs were individually correlated with miR-29 in outlet obstruction. [score:1]
Sparc correlated with the mean of miR-29b and miR-29c (Figure 3F). [score:1]
For miR-29c this would give three waves of repressive influences that together ensure a rapid yet longstanding decrease in outlet obstruction. [score:1]
We therefore propose that c-Myc/Hdac3/Ezh2 and NF-κB are jointly responsible for repression of miR-29b and miR-29c at 10 days and that SMAD3 is responsible for the sustained repression of miR-29c. [score:1]
The impact of miR-29 in outlet obstruction is likely underestimated by measuring levels of mRNAs because an important mechanism of miRNAs is translational repression. [score:1]

Conversely, upregulation of miR-29 levels was observed after stimulation of HSC with the antifibrotic mediator HGF (Figure 8), previously shown to inhibit expression of various collagens [21], [48], [49]. [score:8]
Upregulation of miRNA-29 by HGF and downregulation by TGF-β take part in the anti- or profibrogenic response of HSC, respectively. [score:7]
Indeed, our in vitro data reveal a definite inhibition of collagen type IV, that is the most upregulated collagen form in the fibrotic liver [6], by miR-29. [score:6]
Whereas TGF-β stimulation leads to decreased miR-29 levels, but to pronounced upregulation of collagen synthesis, HGF stimulation leads to elevated miR-29 expression, but to repression of collagen synthesis. [score:6]
However, overexpression of miR-29 in myofibroblastic HSC did not affect the expression of SMA (Figure S1 D). [score:5]
Together, these data demonstrated that miR-29 specifically inhibits transcription and protein expression of collagen I and IV. [score:5]
After demonstrating that repression of the collagen-inhibiting miR-29 is an important downstream TGF–β effect, we studied if miR-29 overexpression can overcome the profibrogenic features mediated by TGF-β such as col1A1 induction. [score:5]
TGF-β treatment resulted in highly increased col1A1 expression in HSC cells treated with scrambled miRNA or with antago-miR-29, but only a moderate col1A1 induction in miR-29 overexpressing HSC after transfection with ago-miR-29. [score:5]
Therefore, miR-29 expression appears to be reciprocally regulated by profibrogenic (TGF-β) and antifibrogenic growth factors (HGF) in HSC, suggesting that miR-29 occupies a central role in responding to the antagonistic actions of HGF and TGF-β in regulating collagen synthesis in activated and transdifferentiated HSC. [score:5]
In agreement with the data on rat HSC, miR-29 is repressed by TGF-β, but upregulated by HGF (Figure S2). [score:4]
While miR-29 and HGF expression was significantly reduced (C,D), hydroxyproline and collagen mRNA were signifcantly increased in BDO livers (B) (*: p<0.05 **:p<0.01; ***: p<0.001). [score:3]
Since miR-29 is thought to be involved in modulating expression of extracellular matrix components (Table S3) [30], [31], [32], [34], this makes them promising candidates for collagen I and IV repression after HGF stimulation of HSC. [score:3]
Keeping with the antifibrotic function of miR-29, miR-29 is reduced in liver biopsies after liver intoxication in mice and after chronic liver disease in humans [35]. [score:3]

miR-29 synthesis in HSC is suppressed by TGF-β, but promoted by HGF. [score:3]

Our results show that obesity -induced pathological cardiac remo deling leads to an increase in cardiac pathological hypertrophy markers and downregulation of microRNA-29c expression, which can be associated with the increase in the LV collagen volumetric fraction. [score:6]
In contrast, AET restored the pathological expression of microRNA-1 and microRNA-29c and their target genes, which likely counteracted the pathological cardiac remo deling and cardiac dysfunction in obesity. [score:5]
Studies have shown that AET increases microRNA-29 expression in the heart and consequently decreases collagen expression and protein levels [24, 25]. [score:5]
To confirm the involvement of obesity-regulated microRNAs in pathological CH, we analyzed the cardiac microRNA-29 family (microRNA-29a, microRNA-29b and microRNA-29c), whose expression affects collagen content. [score:4]
In conclusion, obesity downregulated microRNA-29c in OZR possibly leading to increased cardiac collagen content. [score:4]
Our study demonstrates for the first time that AET was efficient in restoring the microRNA-1 and microRNA-29c to nonpathological levels in obesity, as well as its targets NCX1 and collagen, respectively. [score:3]
The LV interstitial collagen volumetric fraction (CVF) was inversely proportional to the microRNA-29c expression level. [score:3]
Previous data reported by our group showed that physiological CH induced by different amounts of AET is related to reduced cardiac collagen expression via elevated cardiac microRNA-29c levels in healthy rats [24]. [score:3]
Animals trained on a higher intensity protocol presented an increase of 123% in microRNA-29c expression and decreases of 33% and 48% for COLIAI and COLIIIAI, respectively [24]. [score:3]

Soci et al. [24] demonstrated that different intensities of swimming training lead to different magnitudes in the expression of microRNA-29c levels. [score:3]
Animals trained on the same protocol as the current study showed that the microRNA-29c levels decreased by 52% and that COLIAI and COLIIIAI expressions decreased by 27% and 38%, respectively. [score:3]

Thus, AET was able to normalize cardiac microRNA-29c expression and CVF in OZR + TR, and these results suggest that AET has a cardioprotective effect against pathological CH as shown in Figure 8. In our previous study, although there was no statistical difference (p = 0.07), a 25% reduced time E/A wave ratio was found when OZR was compared with untrained LZR [4], suggesting damage in the contractile myocardium.
