Abstract
Targeting circular RNA has been a novel approach to preventing and limiting acute myocardial infarction (AMI). Here, we planned to investigate the role and mechanism of circ_0020887 in AMI progression.Hypoxic injury in human cardiomyocytes (AC16) was measured using cell counting kit-8 assay, 5-ethynyl-2'-deoxyuridine assay, flow cytometry, and colorimetric assay kits. RNA and protein expressions were determined using real-time quantitative PCR and western blotting. Direct interplay between RNAs was determined using dual-luciferase reporter, RNA pull-down, and RIP assays.In the plasma and hypoxia-induced AC16 cells of patients with AMI, circ_0020887 and miR-370-3p were upregulated and downregulated, respectively, concomitant with the upregulation of cytochrome P450 1B1 (CYP1B1). Circ_0020887 interference could inhibit hypoxia-induced AC16 cell apoptosis, oxidative stress, and inflammatory response. Circ_0020887 could sponge miR-370-3p, and miR-370-3p could target CYP1B1. The inhibition effect of circ_0020887 knockdown on hypoxia-induced AC16 cell injury could be reversed by the miR-370-3p inhibitor. Besides, CYP1B1 overexpression also overturned the suppressive effect of miR-370-3p on hypoxia-induced AC16 cell apoptosis, oxidative stress, and inflammatory response.In conclusion, circ_0020887 regulated the miR-370-3p/CYP1B1 axis to regulate hypoxia-induced cardiomyocyte injury, confirming that circ_0020887 might promote cardiomyocyte injury.

Endogenous and viral microRNAs in nasal secretions of water buffaloes (Bubalus bubalis) after Bubaline alphaherpesvirus 1 (BuHV-1) challenge infection. Vet Res 2023; 54:44. [PMID: 37277883 PMCID: PMC10242922 DOI: 10.1186/s13567-023-01175-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2022] [Accepted: 04/19/2023] [Indexed: 06/07/2023] Open
Abstract
Bubaline alphaherpesvirus 1 (BuHV-1) is a pathogen of water buffaloes responsible for economic loss worldwide. MicroRNAs (miRNAs) regulate gene expression produced by alphaherpesviruses and hosts. This study aimed at (a) unravelling the ability of BuHV-1 to produce miRNAs, including hv1-miR-B6, hv1-miR-B8, hv1-miR-B9; (b) measuring the host immune-related miRNAs associated to herpesvirus infection, including miR-210-3p, miR-490-3p, miR-17-5p, miR-148a-3p, miR-338-3p, miR-370-3p, by RT-qPCR; (c) identifying candidate markers of infection by receiver-operating characteristic (ROC) curves; (d) exploiting the biological functions by pathway enrichment analyses. Five water buffaloes BuHV-1 and Bovine alphaherpesvirus 1 (BoHV-1) free were immunized against Infectious Bovine Rhinotracheitis (IBR). Five additional water buffaloes served as negative controls. All animals were challenged with a virulent wild-type (wt) BuHV-1 via the intranasal route 120 days after the first vaccination. Nasal swabs were obtained at days (d) 0, 2, 4, 7, 10, 15, 30, and 63 post-challenge (pc). The animals of both groups shed wt BuHV-1 up to d7 pc. Results demonstrated that (a) miRNAs produced by the host and BuHV-1 could be efficiently quantified in the nasal secretion up to d63 and d15 pc, respectively; b) the levels of host and BuHV-1 miRNAs are different between vaccinated and control buffaloes; c) miR-370-3p discriminated vaccinated and control animals; d) host immune-related miRNAs may modulate genes involved in the cell adhesion pathway of the neuronal and immune system. Overall, the present study provides evidence that miRNAs can be detected in nasal secretions of water buffaloes and that their expression is modulated by BuHV-1.

Abstract
M2 macrophages-derived extracellular vesicles (M2-EVs) serve as a tool for the delivery of miRNAs and play an anti-inflammatory role in diseases. This study sought to explore the role of (M2-EVs) in the proliferation and inflammatory responses of IL-1β-stimulated chondrocytes. M2 macrophages were induced and characterized, followed by isolation and characterization of M2-EVs. Chondrocytes were treated with 10 ng/mL IL-1β and co-cultured with M2 macrophages transfected with Cy3-labeled miR-370-3p. Cell viability, TNF (tumor necrosis factor)-α, IL(Interleukin)-18, IL-10, miR-370-3p, and sex-determining region Y-related high-mobility-group box transcription factor 11 (SOX11) mRNA were determined via cell counting assay kit, colony formation, ELISA, and qRT-PCR. The binding relationship between miR-370-3p and SOX11 was testified via the dual-luciferase assay. The functional rescue experiment was designed to confirm the role of SOX11. M2-EVs improved chondrocyte viability and colony formation, lowered TNF-α and IL-18, and elevated IL-10. M2-EVs delivered miR-370-3p into chondrocytes to upregulate miR-370-3p. Upregulation of miR-370-3p in M2-EVs enhanced the protective role of M2-EVs in chondrocytes. miR-370-3p inhibited SOX11 transcription. SOX11 overexpression attenuated the protective role of M2-EVs in chondrocytes. Overall, our findings suggested that M2-EVs promote proliferation and suppress inflammatory responses in IL-1β-stimulated chondrocytes via the miR-370-3p/SOX11 axis.

Abstract
To investigate the possible effect of FoxO on coxsackievirus B3 (CVB3) -induced cardiomyocyte inflammation and apoptosis via modulation of the TLR4/NF-κB signaling pathway.Viral myocarditis (VMC) models were establied via CVB3 infection both in vivo and in vitro. Western blotting was adopted to detect FoxO1 and TLR4 expressions in myocardial tissues and cells. Cardiomyocytes of suckling mouse were divided into the control, CVB3, CVB3 + pcDNA, CVB3 + pcDNA-FoxO1, CVB3 + TLR4 siRNA, and CVB3 + pcDNA-FoxO1 + TLR4 siRNA groups. Flow cytometry was employed to evaluate cell apoptosis. The expressions of inflammatory factors including TNF-α, IL-1β, and IL-6 were detected via quantitative reverse transcriptase polymerase chain reaction and enzyme-linked immunosorbent assay. Then, TLR4/NF-κB pathway-related proteins were determined via Western blotting.VMC mice had increased FoxO1 and TLR4 expressions in myocardial tissues. Cardiomyocytes with CVB3 infection also had upregulated protein expressions of p-FoxO1/FoxO1 and TLR4. Compared with those in the control group, the cardiomyocytes in the CVB3 group were increased in LDH and CK-MB levels, cell apoptosis rate and inflammatory factors (TNF-α, IL-1β and IL-6), as well as protein expressions of TLR4 and p-p65/p65. Compared with those in the CVB3 group, the cardiomyocytes in the CVB3 + pcDNA-FoxO1 group were further upregulated whereas those in the CVB3 +TLR4 siRNA group were downregulated in the aforementioned indicators. Furthermore, TLR4 siRNA can reverse the effect of pcDNA-FoxO1 on the aggravation of cardiomyocyte injury induced by CVB3 infection.FoxO1 can upregulate the TLR4/NF-κB signaling pathway to promote cardiomyocyte apoptosis and inflammatory injury in CVB3-induced VMC.

Abstract
Healthy mammary gland is essential for milk performance in dairy cows. MicroRNAs (miRNAs) are the key molecules to regulate the steady state of mammary gland in dairy cows. This study investigated the potential role of miR-29c in bovine mammary epithelial cells (bMECs). RNA sequencing (RNA-seq) was used to measure the transcriptome profile of bovine mammary epithelial cells line (MAC-T) transfected with miR-29c inhibitor or negative control (NC) inhibitor, and then differentially expressed genes (DEGs) were screened. The results showed that a total of 42 up-regulated and 27 down-regulated genes were found in the miR-29c inhibitor group compared with the NC inhibitor group. The functional enrichment of the above DEGs indicates that miR-29c is a potential regulator of oxidative stress and inflammatory response in bMECs through multiple genes, such as forkhead box O1 (FOXO1), tumor necrosis factor-alpha (TNF-α), and major histocompatibility complex, class II, DQ alpha 5 (BoLA-DQA5) in the various biological process and signaling pathways of stress-activated mitogen-activated protein kinase (MAPK) cascade, Epstein-Barr virus infection, inflammatory bowel disease, etc. The results imply that miR-29c plays an important role in a steady state of bMECs or cow mammary gland and may be a potential therapeutic target for mastitis in dairy cows.

Abstract
Background Circular RNA (circRNA) has been shown to play an important role in a variety of cardiovascular diseases, including myocardial infarction (MI). However, the role of circRbms1 in MI progression remains unclear. Methods An MI mouse model was constructed in vivo, and cardiomyocytes were cultured under hypoxia condition to induce a cardiomyocyte injury model in vitro. The expression levels of circRbms1, microRNA (miR)-742-3p, and forkhead box O1 (FOXO1) were determined by quantitative real-time PCR. Cell viability, migration, invasion, and apoptosis were measured using Cell Counting Kit-8 assay, transwell assay, and flow cytometry. Meanwhile, western blot analysis was used to examine the protein levels of apoptosis markers and FOXO1. Additionally, dual-luciferase reporter assay, RNA pull-down assay, and RIP assay were employed to verify the interactions between miR-742-3p and circRbms1 or FOXO1. Results CircRbms1 was upregulated in the heart tissues of MI mice and hypoxia-induced cardiomyocytes. Hypoxia induced cardiomyocyte injury by suppressing cell viability, migration, and invasion, and promoting apoptosis. Function experiments showed that circRbms1 overexpression aggravated hypoxia-induced cardiomyocyte injury, while its silencing relieved cardiomyocyte injury induced by hypoxia. Furthermore, circRbms1 sponged miR-742-3p. MiR-742-3p overexpression alleviated hypoxia-induced cardiomyocyte injury, and its inhibitor reversed the suppressive effect of circRbms1 silencing on hypoxia-induced cardiomyocyte injury. Further experiments showed that FOXO1 was a target of miR-742-3p, and its expression was positively regulated by circRbms1. The inhibitory effect of miR-742-3p on hypoxia-induced cardiomyocyte injury was reversed by FOXO1 overexpression. Conclusion CircRbms1 regulated the miR-742-3p/FOXO1 axis to mediate hypoxia-induced cardiomyocyte injury, suggesting that circRbms1 might be an effective target for MI treatment.

Abstract
Twin-twin transfusion syndrome (TTTS) is a rare but serious cause of fetal cardiomyopathy with poorly understood pathophysiology and challenging prognostication. This study sought a nonbiased, comprehensive assessment of amniotic fluid (AF) microRNAs from TTTS pregnancies and associations of these miRNAs with clinical characteristics. For the discovery cohort, AF from ten fetuses with severe TTTS cardiomyopathy were selected and compared to ten normal singleton AF. Array panels assessing 384 microRNAs were performed on the discovery cohort and controls. Using a stringent q < 0.0025, arrays identified 32 miRNAs with differential expression. Top three microRNAs were miR-99b, miR-370 and miR-375. Forty distinct TTTS subjects were selected for a validation cohort. RT-PCR targeted six differentially-expressed microRNAs in the discovery and validation cohorts. Expression differences by array were confirmed by RT-PCR with high fidelity. The ability of these miRNAs to predict clinical differences, such as cardiac findings and later demise, was evaluated on TTTS subjects. Down-regulation of miRNA-127-3p, miRNA-375-3p and miRNA-886 were associated with demise. Our results indicate AF microRNAs have potential as a diagnostic and prognostic biomarker in TTTS. The top microRNAs have previously demonstrated roles in angiogenesis, cardiomyocyte stress response and hypertrophy. Further studies of the mechanism of actions and potential targets is warranted.

Abstract
Background Acute myocardial infarction (AMI) is a common cardiovascular disease with high disability and mortality. Circular RNAs (circRNAs) are implicated in the pathomechanism of multiple human diseases, including AMI. This study intended to explore the function and working mechanism of a novel circRNA circ_0023461 in hypoxia-induced cardiomyocytes. Methods Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and Western blot assay were implemented to detect RNA and protein expression. Cell counting kit-8 (CCK8) assay and 5-ethynyl-2'-deoxyuridine (Edu) assay were conducted to analyze cell viability and proliferation ability. Cell migration and apoptosis were assessed by Transwell assay and flow cytometry. Cell oxidative stress was analyzed using the commercial kits. Enzyme-linked immunosorbent assay (ELISA) was conducted to analyze cell inflammation. Cell glycolytic metabolism was evaluated using the commercial kits. Dual-luciferase reporter assay and RNA pull-down assay were conducted to verify the intermolecular interactions. Results circ_0023461 expression was upregulated in AMI patients and hypoxia-induced AC16 cells. Hypoxia restrained the viability, proliferation, migration, and glycolysis and induced the apoptosis, oxidative stress, and inflammation of AC16 cells, and these effects were attenuated by the silence of circ_0023461. MicroRNA-370-3p (miR-370-3p) was verified as a target of circ_0023461, and circ_0023461 silencing-mediated protective effects in hypoxia-induced cardiomyocytes were partly alleviated by the knockdown of miR-370-3p. miR-370-3p interacted with the 3' untranslated region (3' UTR) of phosphodiesterase 4D (PDE4D), and PDE4D overexpression partly reversed miR-370-3p overexpression-induced protective effects in hypoxia-induced cardiomyocytes. circ_0023461 can upregulate PDE4D expression by acting as a molecular sponge for miR-370-3p in AC16 cells. Conclusion circ_0023461 knockdown attenuated hypoxia-induced dysfunction in AC16 cells partly by targeting the miR-370-3p/PDE4D axis.

Abstract
miRNA-132/212 are small regulators of gene expression with a function that fulfills a vital function in diverse biological processes including neuroprotection of cells with prolonged longevity in neurons and the cardiovascular system. In neurons, miRNA-132 appears to be essential for controlling differentiation, development, and neural functioning. Indeed, it also universally promotes axon evolution, nervous migration, plasticity as well, it is suggested to be neuroprotective against neurodegenerative diseases. Moreover, miRNA-132/212 disorder leads to neural developmental perturbation, and the development of degenerative disorders covering Alzheimer's, Parkinson's, and epilepsy's along with psychiatric perturbations including schizophrenia. Furthermore, the cellular mechanisms of the miRNA-132/212 have additionally been explored in cardiovascular diseases models. Also, the miRNA-132/212 family modulates cardiac hypertrophy and autophagy in cardiomyocytes. The protective and effective clinical promise of miRNA-132/212 in these systems is discussed in this review. To sum up, the current progress in innovative miRNA-based therapies for human pathologies seems of extreme concern and reveals promising novel therapeutic strategies.

BACKGROUND Myocardial infarction (MI), a common type of coronary heart disease, is the major cause of morbidity and mortality around the world. Chemokine-mediated inflammatory cell infiltration and local inflammatory damage response are recent research hotspots. Hence, we attempted to examine the role of C-X-C motif chemokine 16 (CXCL16) as a potential candidate in MI. METHODS Human cardiomyocytes were treated with hypoxia/reoxygenation (H/R) to establish an in vitro cell model. GEO database provided the clinical data of MI patients and GSEA verified the relationship of chemokine and MI. CCK-8 and flow cytometry analyses were used to measure cell viability and apoptosis. Bioinformatics analysis and luciferase reporter assay were conducted to determine the correlation between CXCL16 and miR-545. qRT-PCR and western blot assays were performed to investigate the expression level of the indicated genes. The activity of lactate dehydrogenase (LDH) and the levels of TNF-α, IL-6, IL-1β, and IL-10 were explored using ELISA assay. RESULTS CXCL16 was increased in MI. CXCL16 knockdown can reverse the inhibitory effect of H/R treatment on cell viability, while overexpression of CXCL16 showed the opposite trend. MiR-545 directly targeted CXCL16 and negatively regulated CXCL16 levels. MiR-545 promoted cell proliferation and inhibited apoptosis in the MI cell model, which attenuated the CXCL16-induced injury on cardiomyocytes. CONCLUSION These findings demonstrated that CXCL16 aggravated MI damage through being directly targeted by miR-545 and mediating inflammatory responses, thereby providing potential therapeutic targets for MI therapy.

[PMID: 33250684 PMCID: PMC7689242 DOI: 10.17179/excli2020-2809] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Accepted: 10/21/2020] [Indexed: 01/14/2023]
Abstract
Few studies have addressed the mechanism by which circ_0010729 regulates hypoxia-induced cell injury in cardiovascular diseases. However, its role and its regulatory mechanism in myocardial infarction remain to be explored. Cell viability, cycle, apoptosis, and migration were analyzed using cell counting kit-8 assay, flow cytometry, caspase-3 activity assay kit and transwell assay, respectively. Tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) concentrations were examined by enzyme-linked immunosorbent assay. Glucose metabolism was calculated by detecting ATP production, glucose uptake and lactate production. Levels of circ_0010729, miR-370-3p and TNF Receptor Associated Factor 6 (TRAF6) were detected using quantitative real-time polymerase chain reaction or western blot. The direct interaction between circ_0010729 and TRAF6 or miR-370-3p was verified using dual-luciferase reporter assay and RNA immunoprecipitation assay. Under hypoxia condition, cardiomyocytes suffered from cell viability suppression, cell cycle arrest, cell apoptosis promotion, migration reduction, increase of inflammatory factor IL-6 and TNF-α, as well as glycolysis inhibition. Circ_0010729 expression was up-regulated in the cardiomyocytes at different hypoxia-exposed time points. Circ_0010729 knockdown protected cardiomyocytes against hypoxic dysfunction, while circ_0010729 overexpression showed inverse effects. MiR-370-3p was confirmed to directly bind to circ_0010729 or TRAF6. MiR-370-3p inhibition attenuated the protective effects of circ_0010729 knockdown on hypoxia-modulated cardiomyocyte dysfunction. MiR-370-3p restoration protected cardiomyocytes against hypoxic injury via targeting TRAF6. Besides, circ_0010729 indirectly regulated TRAF6 expression via miR-370-3p. This study demonstrated that circ_0010729 knockdown attenuated hypoxia-induced cardiomyocyte dysfunction via miR-370-3p/TRAF6 axis, indicating a potential therapeutic target for myocardial infarction.

Abstract
Reactive oxygen species (ROS) affect many cellular functions and the proper redox balance between ROS and antioxidants contributes substantially to the physiological welfare of the cell. During pathological conditions, an altered redox equilibrium leads to increased production of ROS that in turn may cause oxidative damage. MicroRNAs (miRNAs) regulate gene expression at the post-transcriptional level contributing to all major cellular processes, including oxidative stress and cell death. Several miRNAs are expressed in response to ROS to mediate oxidative stress. Conversely, oxidative stress may lead to the upregulation of miRNAs that control mechanisms to buffer the damage induced by ROS. This review focuses on the complex crosstalk between miRNAs and ROS in diseases of the cardiac (i.e., cardiac hypertrophy, heart failure, myocardial infarction, ischemia/reperfusion injury, diabetic cardiomyopathy) and pulmonary (i.e., idiopathic pulmonary fibrosis, acute lung injury/acute respiratory distress syndrome, asthma, chronic obstructive pulmonary disease, lung cancer) compartments. Of note, miR-34a, miR-144, miR-421, miR-129, miR-181c, miR-16, miR-31, miR-155, miR-21, and miR-1/206 were found to play a role during oxidative stress in both heart and lung pathologies. This review comprehensively summarizes current knowledge in the field.

[PMID: 32346302 PMCID: PMC7167270 DOI: 10.2147/dmso.s248948] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2020] [Accepted: 03/27/2020] [Indexed: 12/15/2022] Open
Abstract
PURPOSE A high-fat diet (HFD) can lead to cardiac dysfunction, hypertrophy, and fibrosis. This study aimed to explore microRNA expression profiles in the myocardium of HFD-induced obesity rat. MATERIALS AND METHODS Wistar rats were randomly divided into two groups, and fed with normal chow diet (NCD) or HFD for 20 weeks. Cardiac function was evaluated by echocardiography. Left ventricular myocardium was harvested to assess the extent of myocardial morphology alteration. MicroRNA expression was analyzed using Agilent miRNA microarray and quantitative real-time PCR (qRT-PCR) was used to validate the microarray data. The mirdbV6 database was used to forecast the miRNA target genes. The role of microRNAs in palmitate-induced cardiac hypertrophy and fibrosis in primary neonatal rat cardiomyocytes was evaluated by loss- and gain-of-function experiments. RESULTS Significant changes in cardiac function, hypertrophy, fibrosis, and apoptosis were found in HFD rats as compared with NCD rats. miR-141-3p and miR-144-3p were also significantly upregulated in the myocardium of HFD-induced obesity rat. A series of genes involved in essential biological processes, including anatomical structure development and metabolic process, was targeted by these two miRNAs. These target genes were also implicated in signaling pathways involved in the PI3K-Akt signaling pathway, Wnt signaling pathway, autophagy, and protein processing in the endoplasmic reticulum. Inhibition of miR-141 or overexpression of miR-144 attenuated palmitate-induced cardiac hypertrophy and fibrosis. In contrast, overexpression of miR-141 or inhibition of miR-144 aggravated palmitate-induced cardiac hypertrophy and fibrosis. CONCLUSION This study identifies that miR-141 and miR-144 are candidate miRNAs associated with the development of HFD-induced cardiac dysfunction and structure alteration.
