Basic Res Cardiol 2024:10.1007/s00395-024-01076-8. [PMID: 39158697 DOI: 10.1007/s00395-024-01076-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Revised: 08/06/2024] [Accepted: 08/14/2024] [Indexed: 08/20/2024]
Abstract
Exercise is an effective way to alleviate breast cancer-induced cardiac injury to a certain extent. However, whether voluntary exercise (VE) activates cardiac signal transducer and activator of transcription 3 (STAT3) and the underlying mechanisms remain unclear. This study investigated the role of STAT3-microRNA(miRNA)-targeted protein axis in VE against breast cancer-induced cardiac injury.VE for 4 weeks not only improved cardiac function of transgenic breast cancer female mice [mouse mammary tumor virus-polyomavirus middle T antigen (MMTV-PyMT +)] compared with littermate mice with no cancer (MMTV-PyMT -), but also increased myocardial STAT3 tyrosine 705 phosphorylation. Significantly more obvious cardiac fibrosis, smaller cardiomyocyte size, lower cell viability, and higher serum tumor necrosis factor (TNF)-α were shown in MMTV-PyMT + mice compared with MMTV-PyMT - mice, which were ameliorated by VE. However, VE did not influence the tumor growth. MiRNA sequencing identified that miR-181a-5p was upregulated and miR-130b-3p was downregulated in VE induced-cardioprotection. Myocardial injection of Adeno-associated virus serotype 9 driving STAT3 tyrosine 705 mutations abolished cardioprotective effects above. Myocardial STAT3 was identified as the transcription factor binding the promoters of pri-miR-181a (the precursor of miR-181a-5p) and HOX transcript antisense RNA (HOTAIR, sponged miR-130b-3p) in isolated cardiomyocytes. Furthermore, miR-181a-5p targeting PTEN and miR-130b-3p targeting Zinc finger and BTB domain containing protein 20 (Zbtb20) were proved in AC-16 cells. These findings indicated that VE protects against breast cancer-induced cardiac injury via activating STAT3 to promote miR-181a-5p targeting PTEN and to promote HOTAIR to sponge miR-130b-3p targeting Zbtb20, helping to develop new targets in exercise therapy for breast cancer-induced cardiac injury.

Mol Med 2024; 30:83. [PMID: 38867145 PMCID: PMC11167843 DOI: 10.1186/s10020-024-00854-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Accepted: 06/05/2024] [Indexed: 06/14/2024] Open
Abstract
BACKGROUND The terminal stage of ischemic heart disease develops into heart failure (HF), which is characterized by hypoxia and metabolic disturbances in cardiomyocytes. The hypoxic failing heart triggers hypoxia-inducible factor-1α (HIF-1α) actions in the cells sensitized to hypoxia and induces metabolic adaptation by accumulating HIF-1α. Furthermore, soluble monocarboxylic acid transporter protein 1 (MCT1) and mitochondrial pyruvate carrier 1 (MPC1), as key nodes of metabolic adaptation, affect metabolic homeostasis in the failing rat heart. Aerobic exercise training has been reported to retard the progression of HF due to enhancing HIF-1α levels as well as MCT1 expressions, whereas the effects of exercise on MCT1 and MPC1 in HF (hypoxia) remain elusive. This research aimed to investigate the action of exercise associated with MCT1 and MPC1 on HF under hypoxia. METHODS The experimental rat models are composed of four study groups: sham stented (SHAM), HF sedentary (HF), HF short-term exercise trained (HF-E1), HF long-term exercise trained (HF-E2). HF was initiated via left anterior descending coronary artery ligation, the effects of exercise on the progression of HF were analyzed by ventricular ultrasound (ejection fraction, fractional shortening) and histological staining. The regulatory effects of HIF-1α on cell growth, MCT1 and MPC1 protein expression in hypoxic H9c2 cells were evaluated by HIF-1α activatort/inhibitor treatment and plasmid transfection. RESULTS Our results indicate the presence of severe pathological remodelling (as evidenced by deep myocardial fibrosis, increased infarct size and abnormal hypertrophy of the myocardium, etc.) and reduced cardiac function in the failing hearts of rats in the HF group compared to the SHAM group. Treadmill exercise training ameliorated myocardial infarction (MI)-induced cardiac pathological remodelling and enhanced cardiac function in HF exercise group rats, and significantly increased the expression of HIF-1α (p < 0.05), MCT1 (p < 0.01) and MPC1 (p < 0.05) proteins compared to HF group rats. Moreover, pharmacological inhibition of HIF-1α in hypoxic H9c2 cells dramatically downregulated MCT1 and MPC1 protein expression. This phenomenon is consistent with knockdown of HIF-1α at the gene level. CONCLUSION The findings propose that long-term aerobic exercise training, as a non- pharmacological treatment, is efficient enough to debilitate the disease process, improve the pathological phenotype, and reinstate cardiac function in HF rats. This benefit is most likely due to activation of myocardial HIF-1α and upregulation of MCT1 and MPC1.

Abstract
Cardiovascular and metabolic diseases such as hypertension, type 2 diabetes, and obesity develop long-term fibrotic processes in the heart, promoting pathological cardiac remodeling, including after myocardial infarction, reparative fibrotic processes also occur. These processes are regulated by many intracellular signaling pathways that have not yet been completely elucidated, including those associated with microRNA (miRNA) expression. miRNAs are small RNA transcripts (18-25 nucleotides in length) that act as posttranscriptionally regulators of gene expression, inhibiting or degrading one or more target messenger RNAs (mRNAs), and proven to be involved in many biological processes such as cell cycle, differentiation, proliferation, migration, and apoptosis, directly affecting the pathophysiology of several diseases, including cardiac fibrosis. Exercise training can modulate the expression of miRNAs and it is known to be beneficial in various cardiovascular diseases, attenuating cardiac fibrosis processes. However, the signaling pathways modulated by the exercise associated with miRNAs in cardiac fibrosis were not fully understood. Thus, this review aims to analyze the expression of miRNAs that modulate signaling pathways in cardiac fibrosis processes that can be regulated by exercise training.

Abstract
OBJECTIVE Liraglutide is a commonly used hypoglycemic agent in clinical practice, and has been demonstrated to have protective effects against the development of cardiovascular disease. However, its potential role in myocardial fibrosis remains unexplored. The present study aims to assess the impact of liraglutide on the activation of cardiac fibroblasts. METHODS Primary rat adult fibroblasts were isolated, cultured, and randomly allocated into 4 groups: control group, transforming growth factor beta1 (TGFβ1) stimulation group, liraglutide group, and TGFβ1+liraglutide group. Fibroblast activation was induced by TGFβ1. Cell proliferation activity was assessed using the CKK-8 kit, and cellular activity was determined using the MTT kit. Reverse transcrition-quantitative polymerase chain reaction (RT-qPCR) was utilized to quantify the level of collagen transcription, immunofluorescence staining was performed to detect the expression level of type III collagen and α-smooth muscle protein (α-SMA), and immunoblotting was conducted to monitor alterations in signal pathways. RESULTS The addition of 10, 25, 50 and 100 nmol/L of liraglutide did not induce any significant impact on the viability of fibroblasts (P>0.05). The rate of cellular proliferation was significantly higher in the TGFβl stimulation group than in the control group. However, the treatment with 50 and 100 nmol/L of liraglutide resulted in the reduction of TGFβl-induced cell proliferation (P<0.05). The RT-qPCR results revealed that the transcription levels of type I collagen, type III collagen, and α-SMA were significantly upregulated in the TGFβl stimulation group, when compared to the control group (P<0.05). However, the expression levels of these aforementioned factors significantly decreased in the TGFβl+liraglutide group (P<0.05). The immunofluorescence staining results revealed a significant increase in the expression levels of type III collagen and α-SMA in the TGFβl stimulation group, when compared to the control group (P<0.05). However, these expression levels significantly decreased in the TGFβl+liraglutide group, when compared to the TGFβl stimulation group (P<0.05). The Western blotting results revealed that the expression levels of phosphorylated smad2 and smad3 significantly increased in the TGFβl stimulation group, when compared to the control group (P<0.05), while these decreased in the TGFβl+liraglutide group (P<0.05). CONCLUSION Liraglutide inhibits myocardial fibrosis development by suppressing the smad signaling pathway, reducing the activation and secretion of cardiac fibroblasts.

Abstract
BACKGROUND Childhood acute lymphoblastic leukemia survivors' anthracycline-induced cardiotoxicity could be prevented with good cardiorespiratory fitness levels and regular physical activity. This cross-sectional study aimed to assess the association between cardiorespiratory fitness and physical activity with cardiac magnetic resonance parameters. METHODS A total of 96 childhood acute lymphoblastic leukemia survivors underwent a maximal cardiopulmonary exercise test and answered physical activity questionnaires. We calculated the odds ratio of the preventive fraction of regular physical activity (≥150 min/wk) and adequate cardiorespiratory fitness levels (above the median ≥31.4 mL·kg-1·min-1) on cardiac magnetic resonance parameters (left ventricular [LV] and right ventricular [RV] morphological and functional parameters). RESULTS An adequate cardiorespiratory fitness was associated with a significant preventive fraction for LV (up to 84% for LV end-diastolic volume) and RV volumes (up to 88% for RV end-systolic volume). The adjusted analyses highlighted a preventive fraction of 36% to 91% between an adequate cardiorespiratory fitness and LV and RV parameters, late gadolinium enhancement fibrosis, and cardiac magnetic resonance relaxation times. No associations were reported with regular physical activity. CONCLUSIONS This study provides additional evidence regarding the benefits of an adequate cardiorespiratory fitness level for childhood cancer survivors' cardiac health.

Abstract
Objective The purpose of this study was to explore the effect of blood flow-restricted resistance training on myocardial fibrosis in early spontaneously hypertensive rats (SHRs). Methods Four-week-old male Wistar-Kyoto rats and SHRs were randomly divided into the following groups: normal group (WKY), SHR control (SHR-SED) group, high-intensity resistance training (HIRT) group, low- and medium-intensity resistance training (LMIRT) group, and blood flow-restricted low- and medium-resistance training (BFRT) group. Body weight, hemodynamics, cardiac function, myocardial morphology and fibrosis, and the expression levels of transforming growth factor-beta1-Smad (TGFβ-1-Smad) pathway-related proteins in the myocardium were assessed. Results (1) BFRT lowered blood pressure significantly, decreased left ventricular wall thickness, and improved cardiac function. At the same time, BFRT was superior to traditional resistance training in lowering diastolic blood pressure, and was superior to HIRT in improving left ventricular compliance, reducing heart rate, and reducing left ventricular posterior wall and left ventricular mass (P < 0.05). (2) BFRT decreased collagen I and collagen fiber area in the myocardium, increased the collagen III area, and decreased the collagen I/III ratio (P < 0.05). BFRT produced a better proportion of myocardial collagen fibers than did traditional resistance training (P < 0.05). (3) In the myocardium of the BFRT group compared to the traditional resistance training group, the expression of TGFβ-1, Smad2/3/4, p-Smad2/3, CTGF, and TIMP1 was significantly downregulated, MMP2 and TIMP2 were significantly upregulated, the MMP/TIMP ratio significantly increased, and TGFβ-1 expression significantly decreased (P < 0.05). Conclusion BFRT inhibited the TGFβ-1-Smad pathway in the myocardium, downregulated the expression of CTGF, and regulated the balance between MMPs and TIMPs, thereby reducing myocardial fibrosis in SHR, and improving cardiac morphology and function. BFRT also lowered blood pressure, and achieved an effect of early prevention and treatment of hypertension. At the same time, BFRT was superior to traditional resistance training in reducing diastolic blood pressure and adjusting the proportion of myocardial collagen fibers.

ESC Heart Fail 2022; 9:4240-4249. [PMID: 36113868 PMCID: PMC9773777 DOI: 10.1002/ehf2.14151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 08/22/2022] [Accepted: 09/04/2022] [Indexed: 01/19/2023] Open
Abstract
AIMS Low cardiorespiratory fitness (CRF) is associated with greater mortality and morbidity. Galectin-3 (Gal-3) is a prognostic biomarker for fibrosis and heart failure. Gal-3 is also associated with a greater risk for cardiovascular mortality. Whether CRF is related with Gal-3 is unclear. The objective of this study was to assess the sex-specific associations of CRF and Gal-3 levels in the general population. METHODS Gal-3 concentrations were determined using a sandwich enzyme immunoassay in the population-based Study of Health in Pomerania (SHIP-TREND-0). Sex-stratified linear regression models adjusted for age, current smoking status, and renal function were used. Individuals with left ventricular ejection fraction (LVEF) <40%, previous myocardial infarction, atrial fibrillation, chronic lung disease, severe renal disease (estimated glomerular filtration rate <30 mL/min/mm2 ), a history of cancer, and extreme values for Gal-3 (<1st percentile; >99th percentile) were excluded. RESULTS A total of n = 1515 participants with a median age of 49 (IQR: 39-60 years, 48% males) were included. In men, a 1 L/min greater VO2 peak was significantly related to 0.50 ng/mL (95% CI -0.8068 to -0.1938, P < 0.01) less Gal-3. In males, a 1 mL/min/kg higher VO2 peak adjusted for body weight was associated with -0.0286 ng/mL (95% CI -0.0052 to -0.0005, P = 0.02) less Gal-3. When VO2 peak was adjusted for lean mass 1 mL/kg/min more was correlated with a -0.0022 ng/mL (95% CI -0.0043 to -0.0007, P = 0.04) less Gal-3. In women, VO2 peak (β -0.2046 95% CI -0.6541 to 0.2449, P = 0.37) and VO2 peak adjusted for lean mass (β -0.0019 95% CI -0.0421 to -0.0050, P = 0.12) were not related with Gal-3, whereas a 1 mL/min/kg higher VO2 peak adjusted for body weight was significantly associated with a -0.0064 ng/mL lower Gal-3 (95% CI -0.0092 to -0.0035, P < 0.01). There were no differences between pre-menopausal and post-menopausal women. CONCLUSIONS VO2 peak was associated with Gal-3 only in men, but VO2 peak adjusted for body weight in women and men. Our results suggest that the adverse consequences of low CRF may be mediated by Gal-3. Further research is needed to understand the sex-specific association between CRF and Gal-3 and whether they are clinically relevant.

Abstract
OBJECTIVE Cardiac remodeling is a common pathological change in various cardiovascular diseases and can ultimately result in heart failure. Thus, there is an urgent need for more effective strategies to aid in cardiac protection. Our previous work found that sphingosine-1-phosphate (S1P) could ameliorate cardiac hypertrophy. In this study, we aimed to investigate whether S1P could prevent cardiac fibrosis and the associated mechanisms in cardiac remodeling. METHODS Eight-week-old male C57BL/6 mice were randomly divided into a sham, transverse aortic constriction (TAC) or a TAC+S1P treatment group. RESULTS We found that S1P treatment improved cardiac function in TAC mice and that the cardiac fibrosis ratio in the TAC+S1P group was significantly lower and was accompanied by a decrease in α-smooth muscle actin (α-SMA) and collagen type I (COL I) expression compared with the TAC group. We also found that one of the key S1P enzymes, sphingosine kinase 2 (SphK2), which was mainly distributed in cytoblasts, was downregulated in the cardiac remodeling case and recovered after S1P treatment in vivo and in vitro. In addition, our in vitro results showed that S1P treatment activated extracellular regulated protein kinases (ERK) phosphorylation mainly through the S1P receptor 2 (S1PR2) and spurred p-ERK transposition from the cytoplasm to cytoblast in H9c2 cells exposed to phenylephrine. CONCLUSION These findings suggest that SphK2 and the S1PR2/ERK pathway may participate in the anti-remodeling effect of S1P on the heart. This work therefore uncovers a novel potential therapy for the prevention of cardiac remodeling.

Ultrasound-targeted microbubble destruction (UTMD)-mediated miR-150-5p attenuates oxygen and glucose deprivation-induced cardiomyocyte injury by inhibiting TTC5 expression. Mol Biol Rep 2022; 49:6041-6052. [PMID: 35357625 DOI: 10.1007/s11033-022-07392-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2021] [Accepted: 03/16/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Cardiomyocyte injury is a typical feature in cardiovascular diseases. Changes in cardiomyocytes strongly affect the progression of cardiovascular diseases. This work aimed to investigate the biological function and potential mechanism of action of miR-150-5p in cardiomyocytes. METHODS AND RESULTS A myocardial ischemia (MI) injury rat model was constructed to detect miR-150-5p and tetratricopeptide repeat domain 5 (TTC5) expression during heart ischemia injury. Primary cardiomyocytes were isolated for in vitro study. CCK-8 assays were used to detect cardiomyocyte viability. Western blots were used to detect TTC5 and P53 expression. qPCR was utilized to measure RNA expression of miR-150-5p and TTC5. The TUNEL assay was used to determine cell apoptosis. ELISA was used to determine cytokine (TNF-α, IL-1β, IL-6, and IL-8) levels in heart tissues and cell culture supernatants. A dual-luciferase reporter assay was carried out to verify the binding ability between miR-150-5p and TTC5. Oxygen-glucose deprivation (OGD) treatment significantly inhibited cell viability. Ultrasound-targeted microbubble destruction (UTMD)-mediated uptake of miR-150-5p inverted these results. Additionally, UTMD-mediated uptake of miR-150-5p retarded the effects of OGD treatment on cell apoptosis. Besides, UTMD-mediated uptake of miR-150-5p counteracted the effects of OGD treatment on the inflammatory response by regulating cytokine (TNF-α, IL-1β, IL-6, and IL-8) levels. For the mechanism of the protective effect on the heart, we predicted and confirmed that miR-150-5p bound to TTC5 and inhibited TTC5 expression. CONCLUSIONS UTMD-mediated uptake of miR-150-5p attenuated OGD-induced primary cardiomyocyte injury by inhibiting TTC5 expression. This discovery contributes toward further understanding the progression of primary cardiomyocyte injury.

Abstract
The benefits of exercise in humans on the heart have been well recognized for many years. Long-term endurance exercise training can induce physiologic cardiac hypertrophy with normal or enhanced heart function, and provide protective benefits in preventing heart failure. The heart-specific responses that occur during exercise are complex and highly variable. This review mainly focuses on the current understanding of the structural and functional cardiac adaptations to exercise as well as molecular pathways and signaling proteins responsible for these changes. Here, we summarize eight tentative hallmarks that represent common denominators of the exercised heart. These hallmarks are: cardiomyocyte growth, cardiomyocyte fate reprogramming, angiogenesis and lymphangiogenesis, mitochondrial remodeling, epigenetic alteration, enhanced endothelial function, quiescent cardiac fibroblast, and improved cardiac metabolism. A major challenge is to explore the underlying molecular mechanisms for cardio-protective effects of exercise, and to identify therapeutic targets for heart diseases.

Abstract
Background Advances in paediatric cardiology have improved the prognosis of children with inherited cardiac disorders. However, health-related quality of life (QoL) and physical activity have been scarcely analysed in children with inherited cardiac arrhythmia or inherited cardiomyopathy. Moreover, current guidelines on the eligibility of young athletes with inherited cardiac disorders for sports participation mainly rely on expert opinions and remain controversial. Methods The QUALIMYORYTHM trial is a multicentre observational controlled study. The main objective is to compare the QoL of children aged 6 to 17 years old with inherited cardiac arrhythmia (long QT syndrome, Brugada syndrome, catecholaminergic polymorphic ventricular tachycardia, or arrhythmogenic right ventricular dysplasia), or inherited cardiomyopathy (hypertrophic, dilated, or restrictive cardiomyopathy), to that of age and gender-matched healthy subjects. The secondary objective is to assess their QoL according to the disease’s clinical and genetic characteristics, the level of physical activity and motivation for sports, the exercise capacity, and the socio-demographic data. Participants will wear a fitness tracker (ActiGraph GT3X accelerometer) for 2 weeks. A total of 214 children are required to observe a significant difference of 7 ± 15 points in the PedsQL, with a power of 90% and an alpha risk of 5%. Discussion After focusing on the survival in children with inherited cardiac disorders, current research is expanding to patient-reported outcomes and secondary prevention. The QUALIMYORYTHM trial intends to improve the level of evidence for future guidelines on sports eligibility in this population.

Abstract
C1q/tumor necrosis factor (TNF)-related protein 12 (CTRP12) plays a crucial part in cardiovascular diseases especially the coronary artery disease. Nonetheless, it is unrevealed that whether the CTRP12 participates in the progress of cardiac fibrosis. In this study, we investigated whether CTRP12 regulates pathological myocardial fibrosis. We isolated neonatal rat cardiac fibroblasts were cultured with recombination CTRP12 followed by stimulating with Isoproterenol (ISO, 100 µM) for 24 h. Then the adenovirus were used to achieve the CTRP12-overexpressed fibroblasts. In vivo, the C57/B6 mice were subjected to recombinant human CTRP12 (0.2 µg/g/d) for 2 weeks after injected with Isoproterenol (ISO, 10 mg/kg/d for 3 d then 5 mg/kg/d for 11 d, subcutaneously (s.c.), 2 weeks) and mice were also subjected to adenovirus with P38 overexpressing system to explore the mechanism. As a result, CTRP12 significantly inhibit the transformation of cardiac fibroblasts to myofibroblasts and the transcription of cardiac fibrosis-related proteins induced by ISO in vitro. The administration of CTRP12 can effectively reduce the cardiac fibrosis and enhance the cardiac function in mice hearts. The treatment with CTRP12 did not change the expression level of phosphorylated (p)-smad2, smad4, p-extracellular regulated protein kinases 1/2 and c-Jun N-terminal kinase 1/2, but it suppressed the activation of p38. Cardiac overexpression of p38 could abolish this kind of cardioprotective effects by CTRP12. In summary, the CTRP12 protect against the ISO induced cardiac fibrosis via suppressing the p38 signal pathway.

Abstract
Myocardial fibrosis (MFs) is a crucial pathological process that results in cardiac failure in the development of multiple cardiovascular diseases. Puerarin could reportedly be used to treat a variety of cardiovascular diseases. However, the exact mechanism of puerarin on MFs was not clear enough. The separated primary cardiac fibroblasts (CFs) were induced by lipopolysaccharide (LPS) and treated with puerarin. The levels of TNF-α, IL-6, HMGB1, PARP-1, α-SMA, collagen-1, collagen-3, NF-κB pathways were examined by ELISA, immunofluorescence, RT-qPCR, western blot and immunohistochemistry assays. In addition, MFs rats' model was established using transverse aortic constriction (TAC), and the degree of fibrosis was certified by masson staining. We successfully separated primary CFs, and certified that LPS induction could upregulate the levels of PARP-1, HMGB1, inflammatory cytokines and fibrosis-related proteins (α-SMA, collagen-1 and collagen-3). In addition, we proved that puerarin could weaken MFs, and PARP-1 and HMGB1 expressions, which were induced by LPS in primary CFs. In terms of mechanism, HMGB1 expression could be promoted by PARP-1, and PARP-1 could attenuate the therapeutic effect of puerarin on LPS-induced MFs. Besides, PARP-1-HMGB1-NF-κB pathway was related to the protective effect of puerarin on MFs. In vivo, we also verified the protective efficacy of puerarin on MFs induced by TAC, and puerarin also regulated HMGB1-mediated TLR4-NF-κB signaling pathway. We demonstrated that puerarin could ameliorate MFs by downregulating PARP-1 to inhibit HMGB1-mediated TLR4-NF-κB signaling pathway in LPS-induced primary CFs and TAC-induced MFs rats' model.

Abstract
Cardiovascular diseases (CVDs) is the first cause of death worldwide, generally exhibiting a high morbidity, high disability rate and high mortality especially in the elderly persons (>50 years old). Previously, extensive studies have demonstrated that cardiac fibrosis plays cardinal roles in the pathogenesis of CVDs. However, due to the unclear underlying mechanisms of cardiac fibrosis, its clinical intervention remains very lacking. Long non-coding RNAs (lncRNAs), a class of non-coding RNA but differing from microRNAs, are generally considered as transcripts with a length ranging 200 to 100 nucleotides. Recently, accumulating evidence showed that lncRNAs involve in the pathogenesis of cardiac fibrosis. Fendrr (FOXF1 adjacent non-coding developmental regulatory RNA), is a spliced long non-coding RNA transcribed bi-directionally with FOXF1 on the opposite strand. Fendrr has been demonstrated to be essential for normal development of the heart and body wall in mouse, and shows a good anti-fibrotic activity in pulmonary fibrosis. In this study, we aimed to explore the effects of Fendrr on cardiac fibrosis. Intriguingly, we first observed that lncRNA Fendrr was up-regulated in the heart tissues of transverse aortic constriction (TAC) induced cardiac fibrosis mouse models, determined by RT-QPCR. Loss-function of Fendrr significantly alleviated the cardiac fibrosis phenotypes induced by TAC, indicating that Fendrr is required for the pathogenesis of cardiac fibrosis. In mechanism, we demonstrated experimentally that Fendrr directly targeting miR-106b, by which the lncRNA promotes cardiac fibrosis (indicated by the elevation of Col1a1, Col3a1, CTGF and ACTA2 expression) in a miR-106b mediated manner. Collectively, our findings highlight the axis of Fendrr/miR-106b/Samd3 in the pathogenesis of cardiac fibrosis, which may be a promising target for clinical intervention target of cardiac fibrosis.

Abstract
Background In recent years, much evidence has emerged to indicate that exercise can benefit people when performed properly. This review summarizes the exercise interventions used in studies involving mice as they are related to special diseases or physiological status. To further understand the effects of exercise interventions in treating or preventing diseases, it is important to establish a template for exercise interventions that can be used in future exercise-related studies. Methods PubMed was used as the data resource for articles. To identify studies related to the effectiveness of exercise interventions for treating various diseases and organ functions in mice, we used the following search language: (exercise [Title] OR training [Title] OR physical activity [Title]) AND (mice [title/abstract] OR mouse [title/abstract] OR mus [title/abstract]). To limit the range of search results, we included 2 filters: one that limited publication dates to "in 10 years" and one that sorted the results as "best match". Then we grouped the commonly used exercise methods according to their similarities and differences. We then evaluated the effectiveness of the exercise interventions for their impact on diseases and organ functions in 8 different systems. Results A total of 331 articles were included in the analysis procedure. The articles were then segmented into 8 systems for which the exercise interventions were used in targeting and treating disorders: motor system (60 studies), metabolic system (45 studies), cardio-cerebral vascular system (58 studies), nervous system (74 studies), immune system (32 studies), respiratory system (7 studies), digestive system (1 study), and the system related to the development of cancer (54 studies). The methods of exercise interventions mainly involved the use of treadmills, voluntary wheel-running, forced wheel-running, swimming, and resistance training. It was found that regardless of the specific exercise method used, most of them demonstrated positive effects on various systemic diseases and organ functions. Most diseases were remitted with exercise regardless of the exercise method used, although some diseases showed the best remission effects when a specific method was used. Conclusion Our review strongly suggests that exercise intervention is a cornerstone in disease prevention and treatment in mice. Because exercise interventions in humans typically focus on chronic diseases, national fitness, and body weight loss, and typically have low intervention compliance rates, it is important to use mice models to investigate the molecular mechanisms underlying the health benefits from exercise interventions in humans.
