Abstract
Background Corylin, a natural flavonoid, is isolated from the fruit of Psoralea corylifolia L. Nevertheless, the effect of corylin on sepsis-associated cardiac dysfunction is still unclear. The purpose of this study is to determine the role and mechanism of corylin in sepsis related cardiac dysfunction. Methods Experiments were carried out on mice with lipopolysaccharide (LPS) or sepsis induced by cecal ligation and puncture (CLP) or myocardial cell sepsis induced by LPS. Results Administration of corylin improved cardiac dysfunction induced by LPS or CLP in mice. Corylin inhibited the increases of interleukin-1 (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α in the heart of mice with LPS or CLP. LPS elevated the levels of IL-1β, IL-6 and TNF-α in cardiomyocytes, which were inhibited by corylin treatment. Corylin attenuated the increases of microRNA (miRNA)-214-5p in the heart of mice with LPS, CLP, LPS-treated NRCMs, H9c2 and AC16 cells. Administration of miRNA-214-5p agomiR reversed the improving effects of corylin on the damaged cardiac function and the increases of IL-1β, IL-6 and TNF-α in mice treated with LPS. Conclusion These outcomes indicated that corylin improved sepsis-associated cardiac dysfunction by inhibiting inflammation. And corylin inhibited inflammation of sepsis by decreasing miRNA-214-5p. Downregulation of miRNA-214-5p improved sepsis-associated cardiac dysfunction and inhibited inflammatory factors.

Abstract
Background This study aimed to investigate the effect and mechanism of Pentraxin 3 (PTX3) on myocardial injury in sepsis. Methods Thirty male C57BL/6 mice were randomly assigned to Groups A, B, or C. Mice in Groups A and B were injected with unloaded lentivirus, while mice in Group C were injected with lentivirus encoding PTX3 overexpression. Seven days after injection, septic myocardial injury mouse models were constructed following intraperitoneal injection with LPS in Groups B and C, and mice in Group A were intraperitoneally injected with normal saline. Cardiac function was examined using echocardiography; pathological variation of myocardial cells was measured through HE staining, transmission electron microscopy, and TUNEL staining; and Western blot was used to measure the expression of PI3K/AKT/mTOR pathway-related, autophagy-related, and apoptosis-related proteins in mice myocardial cells. Results PTX3 significantly improved cardiac function and structure in sepsis-stricken mice, and PTX3 alleviated cardiac damage caused by sepsis. PTX3 reduced the relative protein expression of p-PI3K, p-AKT, mTOR, LC3I/II, Beclin, ATG5, Bax, Caspase-3, and Caspase-9 in septic mouse cardiomyocytes and increased the relative protein expression of Bcl-2. Conclusion PTX3 can attenuate myocardial injury in sepsis due to the down-regulation of apoptosis and autophagy induced by the PI3K/AKT/mTOR pathway.

Abstract
The development of sepsis can lead to many organ dysfunction and even death. Myocardial injury is one of the serious complications of sepsis leading to death. New evidence suggests that microRNAs (miRNAs) play a critical role in infection myocardial injury. However, the mechanism which miR-208a-5p regulates sepsis-induced myocardial injury remains unclear. To mimic sepsis-induced myocardial injury in vitro, rat primary cardiomyocytes were treated with LPS. Cell viability and apoptosis were tested by CCK-8 and flow cytometry, respectively. The secretion of inflammatory factors was analyzed by ELISA. mRNA and protein levels were detected by RT-qPCR and Western blotting. The interaction among SP1, XIAP and miR-208a-5p was detected using dual luciferase report assay. Ultrasonic analysis and HE staining was performed to observe the effect of miR-208a-5p in sepsis-induced rats. Our findings indicated that miR-208a-5p expression in primary rat cardiomyocytes was increased by LPS. MiR-208a-5p inhibitor reversed LPS-induced cardiomyocytes injury through inhibiting the apoptosis. Furthermore, the inflammatory injury in cardiomyocytes was induced by LPS, which was rescued by miR-208a-5p inhibitor. In addition, downregulation of miR-208a-5p improved LPS-induced sepsis myocardial injury in vivo. Mechanistically, XIAP might be a target gene of miR-208a-5p. SP1 promoted transcription of miR-208a by binding to the miR-208a promoter region. Moreover, silencing of XIAP reversed the regulatory of miR-208a-5p inhibitor on cardiomyocytes injury. To sum up, those findings revealed silencing of miR-208a-5p could alleviate sepsis-induced myocardial injury, which would grant a new process for the treatment of sepsis.

Abstract
INTRODUCTION Endothelial injury is a major characteristic of sepsis and contributes to sepsis-induced multiple-organ dysfunction. In this study, we investigated the role of miR-107-3p in sepsis-induced endothelial injury. METHODS Human umbilical vein endothelial cells (HUVECs) were exposed to 20 μg/mL of lipopolysaccharide (LPS) for 6-48 h. The levels of miR-107-3p and kallikrein-related peptidase 5 (KLK5) were examined. HUVECs were treated with LPS for 12 h and subsequently transfected with miR-107-3p inhibitor, KLK5 siRNA, or cotransfected with KLK5 siRNA and miR-107-3p inhibitor/negative control inhibitor. Cell survival, apoptosis, invasion, cell permeability, inflammatory response, and the Toll-like receptor 4/nuclear factor κB signaling were evaluated. In addition, the relationship between miR-107-3p and KLK5 expression was predicted and verified. RESULTS LPS significantly elevated miR-107-3p levels, which peaked at 12 h. Conversely, the KLK5 level was lower in the LPS group than in the control group and was lowest at 12 h. MiR-107-3p knockdown significantly attenuated reductions in cell survival and invasion, apoptosis promotion, hyperpermeability and inflammation induction, and activation of the NF-κB signaling caused by LPS. KLK5 knockdown had the opposite effect. Additionally, KLK5 was demonstrated as a target of miR-107-3p. MiR-107-3p knockdown partially reversed the effects of KLK5 depletion in LPS-activated HUVECs. CONCLUSIONS Our findings indicate that miR-107-3p knockdown may protect against sepsis-induced endothelial cell injury by targeting KLK5. This study identified a novel therapeutic target for sepsis-induced endothelial injury.

Abstract
Myocardial cell damage is associated with apoptosis and excessive inflammatory response in sepsis. Histone deacetylases (HDACs) are implicated in the progression of heart diseases. This study aims to explore the role of histone deacetylase 9 (HDAC9) in sepsis-induced myocardial injury. Lipopolysaccharide (LPS)-induced Sprague Dawley rats and cardiomyocyte line H9C2 were used as models in vivo and in vitro. The results showed that HDAC9 was significantly upregulated after LPS stimulation, and HDAC9 knockdown remarkably improved cardiac function, as evidenced by decreased left ventricular internal diameter end diastole (LVEDD) and left ventricular internal diameter end systole (LVESD), and increased fractional shortening (FS)% and ejection fraction (EF)%. In addition, HDAC9 silencing alleviated release of inflammatory cytokines (tumor necrosis factor-α (TNF-α), IL-6 and IL-1β) and cardiomyocyte apoptosis in vivo and in vitro. Furthermore, HDAC9 inhibition was proved to suppress nuclear factor-kappa B (NF-κB) activation with reducing the levels of p-IκBα and p-p65, and p65 nuclear translocation. Additionally, interaction between miR-214-3p and HDAC9 was determined through bioinformatics analysis, RT-qPCR, western blot and dual luciferase reporter assay. Our data revealed that miR-214-3p directly targeted the 3'UTR of HDAC9. Our findings demonstrate that HDAC9 suppression ameliorates LPS-induced cardiac dysfunction by inhibiting the NF-κB signaling pathway and presents a promising therapeutic agent for the treatment of LPS-stimulated myocardial injury.

Abstract
The impact of N6-methyladenosine (m6A) modification on pri-miRNA in sepsis-induced cardiomyopathy (SICM), and its underlying regulatory mechanism, have not been fully elucidated. We successfully constructed a SICM mice model through cecal ligation and puncture (CLP). In vitro, a lipopolysaccharide (LPS)-induced HL-1 cells model was also established. The results showed that sepsis frequently resulted in excessive inflammatory response concomitant with impaired myocardial function in mice exposed to CLP, as indicated by decreases in ejection fraction (EF), fraction shortening (FS), and left ventricular end diastolic diameters (LVDd). miR-193a was enriched in CLP mice heart and in LPS-treated HL-1 cells, while overexpression of miR-193a significantly increased the expression levels of cytokines. Sepsis-induced enrichment of miR-193a significantly inhibited cardiomyocytes proliferation and enhanced apoptosis, while this was reversed by miR-193a knockdown. Furthermore, under our experimental conditions, enrichment of miR-193a in SICM could be considered excessively maturated on pri-miR-193a by enhanced m6A modification. This modification was catalyzed by sepsis-induced overexpression of methyltransferase-like 3 (METTL3). Moreover, mature miRNA-193a bound to a predictive sequence within 3'UTRs of a downstream target, BCL2L2, which was further validated by the observation that the BCL2L2-3'UTR mutant failed to decrease luciferase activity when co-transfected with miRNA-193a. The interaction between miRNA-193a and BCL2L2 resulted in BCL2L2 downregulation, subsequently activating the caspase-3 apoptotic pathway. In conclusion, sepsis-induced miR-193a enrichment via m6A modification plays an essential regulatory role in cardiomyocyte apoptosis and inflammatory response in SICM. The detrimental axis of METTL3/m6A/miR-193a/BCL2L2 is implicated in the development of SICM.

Anal Cell Pathol (Amst) 2023; 2023:3154223.

Abstract
Purpose Long non-coding RNAs (LncRNAs) OIP5-AS1 and miR-25-3p play important roles in myocardial injury, whereas their roles in lipopolysaccharide (LPS)-induced myocardial injury remain unknown. The purpose of our study was to investigate the functional mechanisms of OIP5-AS1 and miR-25-3p in LPS-induced myocardial injury. Methods Rats and H9C2 cells were treated with LPS to establish the model of myocardial injury in vivo and in vitro, respectively. The expression levels of OIP5-AS1 and miR-25-3p were determined by quantitative reverse transcriptase-polymerase chain reaction. Enzyme-linked immunosorbent assay was performed to measure the serum levels of IL-6 and TNF-α. The relationship between OIP5-AS1 and miR-25-3p/NOX4 was determined by luciferase reporter assay and/or RNA immunoprecipitation assay. The apoptosis rate was detected by flow cytometry, and cell viability was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay. Western blot was performed to detect the protein levels of Bax, Bcl-2, caspase3, c-caspase3, NOX4, and p-NF-κB p65/NF-κB p65. Results OIP5-AS1 was up-regulated, and miR-25-3p was down-regulated in myocardial tissues of LPS-induced rats and LPS-treated H9C2 cells. Knockdown of OIP5-AS1 relieved the myocardial injury in LPS-induced rats. Knockdown of OIP5-AS1 also inhibited the inflammation and apoptosis of myocardial cells in vivo, which was subsequently confirmed by in vitro experiments. In addition, OIP5-AS1 targeted miR-25-3p. MiR-25-3p mimics reversed the effects of OIP5-AS1 overexpression on promoting cell apoptosis and inflammation and on inhibiting cell viability. Besides, miR-25-3p mimics blocked the NOX4/NF-κB signalling pathway in LPS-induced H9C2 cells. Conclusion Silencing of lncRNA OIP5-AS1 alleviated LPS-induced myocardial injury by regulating miR-25-3p.

Abstract
ABSTRACT Sepsis is a complex disease resulting from a dysregulated inflammatory response to an infection. Initiation of sepsis occurs from a localized infection that disseminates to the bloodstream placing all organ systems at risk. Septic shock is classically observed to manifest itself as systemic hypotension with hyporesponsiveness to vasopressor agents. Myocardial dysfunction occurs resulting in an inability to perfuse major organ systems throughout the body. Most importantly, the brain is hypoperfused creating an ischemic and inflammatory state resulting in the clinical observation of acute mental status changes and cognitive dysfunction commonly known as sepsis-associated encephalopathy. This short review describes the inflammatory molecular mechanisms of myocardial dysfunction, discusses the evidence of the dual roles of the microglia resulting in blood-brain barrier disruption, and suggests that septic-derived exosomes, endosome-derived lipid bilayer spheroids released from living cells, influence cardiac and neurological cellular function.

Abstract
Myocardial injury is the most prevalent and serious complication of sepsis. The potential of puerarin (Pue) to treat sepsis-induced myocardial injury (SIMI) has been recently reported. Nevertheless, the specific anti-SIMI mechanisms of Pue remain largely unclear. Integrating network pharmacology, bioinformatics analysis, and experimental validation, we aimed to clarify the anti-SIMI mechanisms of Pue, thereby furnishing novel therapeutic targets. Pue-associated targets were collected from HIT, GeneCards, SwissTargetPrediction, SuperPred, and CTD databases. SIMI-associated targets were acquired from GeneCards and DisGeNET. Differentially expressed genes (DEGs) were identified from GEO database. Potential anti-SIMI targets of Pue were determined using VennDiagram. ClusterProfiler was employed for GO and KEGG analyses. STRING database and Cytoscape were used for protein-protein interaction (PPI) network construction, and cytoHubba was used for hub target screening. PyMOL and AutoDock were utilized for molecular docking. An in vitro SIMI model was built to further verify the therapeutic mechanisms of Pue. Seventy-three Pue-SIMI-DEG intersecting target genes were obtained. GO and KEGG analyses revealed that the targets were principally concentrated in cellular response to chemical stress, response to oxidative stress (OS), and insulin and neurotrophin signaling pathways. Through PPI analysis and molecular docking, AKT1, CASP3, TP53, and MAPK3 were identified as the pivotal targets. In vivo experiments indicated that Pue promoted cell proliferation, downregulated AKT1, CASP3, TP53, and MAPK3, and inhibited inflammation, myocardial injury, OS, and apoptosis in the cell model. Pue might inhibit inflammation, myocardial injury, OS, and apoptosis to treat SIMI by reducing AKT1, CASP3, TP53, and MAPK3.

Abstract
ABSTRACT Background: The exact molecular mechanisms underlying sepsis remain unclear. Accumulating evidence has shown that noncoding RNAs (ncRNAs) are involved in sepsis and sepsis-associated organ dysfunction (SAOD). Methods: We performed this updated systematic review focusing mainly on research conducted in the last 5 years regarding ncRNAs associated with sepsis and SAOD. The following medical subject headings were used in the PubMed database from October 1, 2016, to March 31, 2022: "microRNA," "long noncoding RNA," "circular RNA," "sepsis," and/or "septic shock." Studies investigating the role of ncRNAs in the pathogenesis of sepsis and as biomarkers or therapeutic targets in the disease were included. Data were extracted in terms of the role of ncRNAs in the pathogenesis of sepsis and their applicability for use as biomarkers or therapeutic targets in sepsis. The quality of the studies was assessed using a modified guideline from the Systematic Review Center for Laboratory Animal Experimentation. Results: A total of 537 original studies investigated the potential roles of ncRNAs in sepsis and SAOD. Experimental studies in the last 5 years confirmed that long ncRNAs have important regulatory roles in sepsis and SAOD. However, studies on circular RNAs and sepsis remain limited, and more studies should be conducted to elucidate this relationship. Among the included studies, the Systematic Review Center for Laboratory Animal Experimentation scores ranged from 3 to 7 (an average score of 3.78). Notably, 94 ncRNAs were evaluated as potential biomarkers for sepsis, and selective reporting of the sensitivity, specificity, and receiver operating characteristic curve was common. A total of 117 studies demonstrated the use of ncRNAs as potential therapeutic targets in sepsis and SAOD. At a molecular level, inflammation-related pathways, mitochondrial dysfunction, cell apoptosis, and/or oxidative stress were the most extensively studied. Conclusion: This review suggests that ncRNAs could be good biomarkers and therapeutic candidates for sepsis and SAOD. Prospective, large-scale, and multicenter cohort studies should be performed to evaluate specific ncRNAs as biomarkers and test the organ-specific delivery of these regulatory molecules when used as therapeutic targets.

Abstract
It has been reported that lncRNA GAS5 can inhibit LPS-induced inflammation, indicating its involvement in sepsis. We observed the downregulation of GAS5 in plasma of sepsis patients. In addition, expression levels of GAS5 were positively correlated with the expression levels of miR-214. In cardiomyocytes, overexpression of GAS5 upregulated the expression of miR-214, while its knockdown resulted in decreased expression levels of miR-124. Methylation-specific PCR (MSP) revealed that GAS5 negatively regulated the methylation of miR-124. Cell apoptosis showed that overexpression of GAS5 and miR-214 suppressed the apoptosis of cardiomyocytes induced by LPS. In addition, overexpression of miR-214 also reduced the enhancing effects of silencing of GAS5 on cell apoptosis. Therefore, GAS5 may upregulate miR-214 through methylation pathway to inhibit the apoptosis of cardiomyocytes in sepsis.

Expression of MicroRNAs in Sepsis-Related Organ Dysfunction: A Systematic Review. Int J Mol Sci 2022; 23:ijms23169354.

Abstract
Sepsis is a critical condition characterized by increased levels of pro-inflammatory cytokines and proliferating cells such as neutrophils and macrophages in response to microbial pathogens. Such processes lead to an abnormal inflammatory response and multi-organ failure. MicroRNAs (miRNA) are single-stranded non-coding RNAs with the function of gene regulation. This means that miRNAs are involved in multiple intracellular pathways and thus contribute to or inhibit inflammation. As a result, their variable expression in different tissues and organs may play a key role in regulating the pathophysiological events of sepsis. Thanks to this property, miRNAs may serve as potential diagnostic and prognostic biomarkers in such life-threatening events. In this narrative review, we collect the results of recent studies on the expression of miRNAs in heart, blood, lung, liver, brain, and kidney during sepsis and the molecular processes in which they are involved. In reviewing the literature, we find at least 122 miRNAs and signaling pathways involved in sepsis-related organ dysfunction. This may help clinicians to detect, prevent, and treat sepsis-related organ failures early, although further studies are needed to deepen the knowledge of their potential contribution.

Abstract
Sepsis is an abnormal condition with multiple organ dysfunctions caused by the uncontrolled infection response and one of the major diseases that seriously hang over global human health. Besides, sepsis is characterized by high morbidity and mortality, especially in intensive care unit (ICU). Among the numerous subsequent organ injuries of sepsis, myocardial injury is one of the most common complications and the main cause of death in septic patients. To better manage septic inpatients, it is necessary to understand the specific mechanisms of sepsis induced myocardial injury (SIMI). Therefore, this review will elucidate the pathophysiology of SIMI from the following certain mechanisms: apoptosis, mitochondrial damage, autophagy, excessive inflammatory response, oxidative stress and pyroptosis, and outline current therapeutic strategies and potential approaches in SIMI.

Abstract
Sepsis is a public health problem worldwide. This study investigated the mechanism of miR-107 on sepsis-induced myocardial injury. Sepsis rat models were established by cecal ligation and puncture (CLP), and the cell model was established using lipopolysaccharide (LPS)-induced cardiomyocytes. Cardiac function indexes of rats were measured using echocardiography. Pathological changes in the rat myocardium were observed using histological staining. Expression of miR-107 in the serum of rats and in cardiomyocytes was detected after the treatment with miR-107 mimic and/or pcDNA3.1-PTEN, followed by assessment of cell cycle, proliferation, and apoptosis. Binding sites of miR-107 and PTEN were predicted. PTEN, PI3K, p-PI3K, AKT, and p-AKT levels in LPS-induced cardiomyocytes were measured. miR-107 was significantly downregulated in the serum of CLP rats and LPS-induced cardiomyocytes. miR-107 overexpression remarkably improved cardiac function and histological changes, decreased inflammatory factors, and alleviated the sepsis-induced myocardial injury in rats. In LPS-induced cardiomyocytes, miR-107 overexpression increased cardiomyocyte proliferation, inhibited apoptosis, and enhanced the proportion of cardiomyocytes arrested in S and G2/M phases. miR-107 targeted PTEN. PTEN overexpression partially reversed the inhibition of miR-107 mimic on cardiomyocyte apoptosis. miR-107 overexpression activated the PI3K/AKT pathway by inhibiting PTEN. To conclude, miR-107 activates the PI3K/AKT pathway by inhibiting PTEN, thus attenuating sepsis-induced myocardial injury and LPS-induced cardiomyocyte apoptosis.

Abstract
Myocardial injury is a frequently occurring complication of sepsis. This study aims to investigate the molecular mechanism of long noncoding RNA (lncRNA) small nucleolar RNA host gene 1 (SNHG1)‐mediated DNA methyltransferase 1/B‐cell lymphoma‐2 (DNMT1/Bcl‐2) axis in sepsis‐induced myocardial injury. Mice and HL‐1 cells were treated with lipopolysaccharide (LPS) to establish animal and cellular models simulating sepsis and inflammation. LncRNA SNHG1 was screened out as a differentially expressed lncRNA in sepsis samples through microarray profiling, and the upregulated expression of lncRNA SNHG1 was confirmed in myocardial tissues of LPS‐induced septic mice and HL‐1 cells. Further experiments suggested that silencing of lncRNA SNHG1 reduced the inflammation and apoptotic rate of LPS‐induced HL‐1 cells. LncRNA SNHG1 inhibited Bcl‐2 expression by recruiting DNMT1 to Bcl‐2 promoter region to cause methylation. Inhibition of Bcl‐2 promoter methylation reduced the inflammation and apoptotic rate of LPS‐induced HL‐1 cells. In vivo experiments substantiated that lncRNA SNHG1 silencing alleviated sepsis‐induced myocardial injury in mice. Taken together, lncRNA SNHG1 promotes LPS‐induced myocardial injury in septic mice by downregulating Bcl‐2 through DNMT1‐mediated Bcl‐2 methylation.

Abstract
Acute urethral injuries caused by urethral endoscopy and other mechanical injuries are the main reasons for secondary infection and late urethral stricture. However, there are no studies to explore the transcriptomic changes in urethral injury and the molecular mechanism of urethral injury, which is important for the treatment and cure of urethral injury. Therefore, we used RNA-seq and sRNA-seq profiles from normal and injured urethral tissues to identify and characterize differentially expressed mRNAs and miRNAs. In total, we found 166 differentially expressed mRNAs, of which 69 were upregulated, and 97 were downregulated in injured urethral tissues. The differentially expressed mRNAs were mainly involved in the positive regulation of epithelial cell differentiation, focal adhesion, cell adhesion molecules, protein activation cascade, complement activation, complement and coagulation cascades, and chemokine-mediated signaling pathway. Additionally, we found six upregulated and four downregulated miRNAs, respectively, in the injured urethral tissues. Notably, their target genes were involved in the vascular endothelial growth factor receptor 2 binding, PI3k-Akt signaling pathway, and Notch signaling pathway. In summary, our results suggest that the cell damage response induced by mechanical injury activates the pathological immune response in a variety of ways in injured urethral tissues.

Abstract
The present study was designed to investigate the involvement of miR-23a-3p in the progression of sepsis-induced acute kidney injury (AKI). The expression levels of miR-23a-3p and wnt5a in sepsis-induced AKI patients and lipopolysaccharide (LPS)-treated HK-2 cells were detected by real-time PCR and western blotting. Then, the effects of miR-23a-3p overexpression on cell viability, apoptosis, and inflammatory cytokines secretion in LPS-stimulated HK-2 cells were investigated. Moreover, luciferase reporter assay was performed to confirm the regulatory relationship between miR-23a-3p and wnt5a. Whether miR-23a-3p regulated the activation of Wnt/β-catenin signaling was also explored. mR-23a-3p was lowly expressed in the serum of patients with sepsis-associated AKI and in LPS-treated HK-2 cells. In addition, the overexpression of miR-23a-3p restrained LPS-induced proliferation inhibition and promotion of apoptosis and cytokine production in HK-2 cells. Moreover, wnt5a was identified as a target of miR-23a-3p, which could be negatively regulated by miR-23a-3p. Overexpression of miR-23a-3p suppressed the activation of Wnt/β-catenin signaling in LPS-treated HK-2 cells, which was markedly reversed by wnt5a upregulation. Upregulation of miR-23a-3p may alleviate LPS-induced cell injury by targeting wnt5a and inactivating Wnt/β-catenin pathway, which may serve as a novel therapeutic target for sepsis-associated AKI.

Abstract
Currently, sepsis-induced cardiomyopathy (SIC) remains as one of the most critical clinical syndromes in terminally ill patients. Noncoding RNAs (including microRNAs and long noncoding RNAs) are implicated in both the onset and development of SIC. We herein investigated the functional role and molecular target of long noncoding RNA small nucleolar RNA host gene 16 (SNHG16) in an in vitro SIC model of H9c2 myocardial cells. We used lipopolysaccharide (LPS) as endotoxin to treat H9c2 cells to mimic SIC damages. Cell Counting Kit 8 and apoptosis assay were performed to assess cell proliferation and cell death. Quantitative real-time-PCR and Western blot were employed to examine gene expression level at mRNA and protein level. Dual luciferase assay is used to validate the functional interactions between SNHG16/mi-R421 and miR-421/suppressor of cytokine signaling 5 (SOCS5). Inflammatory cytokines were measured by ELISA. Superoxide dismutase and malondialdehyde measurement was performed to assess oxidative stress, which was further confirmed by 2',7'-dichlorofluorescin diacetate staining. Our data demonstrated that in the LPS-induced sepsis model of myocardial cells, SNHG16 overexpression downregulated the expression level of miR-421, which sustained the expression of SOCS5 to alleviate the adverse effects of LPS, such as apoptosis, pro-inflammatory cytokines, and oxidative stress. Our data suggest that SNHG16 functions as a ceRNA to maintain SOCS5 level by targeting miR-421, thereby attenuating LPS-induced myocardial cell damages. Targeting miR-421 or modulating lncRNA SNHG16 level may be leveraged as a beneficial strategy against sepsis-induced cellular damage in cardiomyocytes.

Abstract
This study aims to investigate the effects of miR-29b-3p on the inflammation injury of human umbilical vein endothelial cells (HUVECs) induced by lipopolysaccharide (LPS) and explore the underlying mechanisms. The effects of different concentrations of LPS (0, 1, 5 and 10 μg/mL) on inflammation injury in HUVECs are detected by ELISA, CCK-8, EdU, flow cytometry and western blot analyses to determine the optimal stimulus concentration. After stimulating HUVECs with 10 μg/mL LPS, the expression levels of miR-29b-3p are detected, and the effects of miR-29b-3p on inflammation injury are detected by ELISA, CCK-8, EdU, flow cytometry and western blot analyses. Bioinformatic analysis, luciferase reporter assay and confirmatory experiments are applied to identify the target gene bound with miR-29b-3p. Rescue experiments have verified the roles of miR-29b-3p and the target gene in inflammation injury. We found that pro-inflammatory factor was increased, apoptosis was promoted, and cell proliferation was inhibited after the treatment of LPS in HUVECs. Overexpression of miR-29b-3p inhibited LPS-induced inflammatory response and apoptosis while promoting proliferation in HUVECs. Besides, bioinformatics analysis indicated that SEC23A was the target gene of miR-29b-3p and the confirmatory experiments showed that SEC23A was negatively correlated with miR-29b-3p and positively correlated with LPS concentration. Rescue experiments revealed that overexpression of SEC23A partially enhanced the inflammation injury effects in LPS-induced HUVECs with overexpression of miR-29b-3p. Hence, miR-29b-3p repressed inflammatory response, cell apoptosis and promoted cell proliferation in LPS-induced HUVECs by targeting SEC23A, providing a potential target for treating sepsis.

Abstract
OBJECTIVE Sepsis is a leading cause of morbidity and mortality after surgery. We aimed to explore the role of long non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) sponging microRNA-26a-5p in sepsis-induced myocardial injury by regulating regulator of calcineurin 2 (Rcan2). METHODS HL-1 cells were incubated with lipopolysaccharide (LPS) to induce in vitro cardiomyocyte injury models, which were then treated with silenced MALAT1 vector, miR-26a-5p mimic or Rcan2 overexpression vector. Next, inflammatory factor level and apoptosis of cells were determined. The in vivo mouse models were constructed by intraperitoneal injection of LPS. The modeled mice were injected with relative oligonucleotides and the pathology, apoptosis, and inflammation in mouse myocardial tissues were assessed. Expression of MALAT1, miR-26a-5p and Rcan2 in vivo and in vitro was evaluated. RESULTS MALAT1 and Rcan2 were upregulated while miR-26a-5p was downregulated in LPS-treated HL-1 cells and mice. MALAT1 silencing or miR-26a-5p upregulation suppressed LPS-induced inflammation and apoptosis of cardiomyocytes in cellular and animal models. These effects of elevated miR-26a-5p could be reversed by upregulating Rcan2, and MALAT1 knockdown-induced ameliorative impacts could be reversed by miR-26a-5p downregulation. CONCLUSION MALAT1 silencing elevated miR-26a-5p to ameliorate LPS-induced myocardial injury by reducing Rcan2. Our research may provide novel biomarkers for the treatment of sepsis.

Abstract
Long non-coding RNA (lncRNA) is considered a crucial modulator of the initiation and progression of several diseases. However, the roles of lncRNA in sepsis have yet to be fully elucidated. Thus, the aim of the present study was to investigate the effects of the lncRNA GDP-mannose 4,6-dehydratase antisense 1 (GMDS-AS1) and its target in order to understand its role in the pathogenesis of sepsis. An in vitro sepsis model was established by lipopolysaccharide (LPS) induction. Reverse transcription-quantitative PCR analysis was applied to detect the expression of inflammatory cytokines and the levels of GMDS-AS1, microRNA (miR)-96-5p and caspase-2 (CASP2). Flow cytometry was used to quantify the rate of apoptosis. In addition, the interaction between miR-96-5p and CASP2 was verified using a luciferase reporter assay. Western blot analysis was performed to assess the protein levels of CASP2 following alterations in GMDS-AS1 and miR-96-5p expression using transfection. The levels of interleukin (IL)-6, tumor necrosis factor-α and IL-1β were increased by LPS treatment in THP-1 cells, whereas miR-96-5p expression was downregulated. miR-96-5p overexpression inhibited LPS-induced inflammatory responses and apoptosis. In addition, GMDS-AS1 expression increased, and upregulation of GMDS-AS1 inhibited, the expression of miR-96-5p in the in vitro sepsis model. Moreover, CASP2 was confirmed to be a direct target of miR-96-5p. Therefore, the lncRNA GMDS-AS1 regulated inflammatory responses and apoptosis by modulating CASP2 and sponging miR-96-5p in LPS-induced THP-1 cells. In summary, the findings of the present study demonstrated that lncRNA GMDS-AS1 could promote the development of sepsis by targeting miR-96-5p/CASP2, indicating that the GMDS-AS1/miR-96-5p/CASP2 axis may be a new therapeutic target and potential research direction for sepsis therapy.

Abstract
Introduction: Sepsis can cause acute lung injury (ALI), one of the leading causes of death in critically ill patients. The underlying mechanisms of sepsis-induced acute lung injury include excessive inflammation, oxidative stress, cell apoptosis, pulmonary edema, and lung tissue dysfunction. Recent studies have shown that miRNA-21 (miR-21) plays a vital role in sepsis-induced acute kidney injury. Relatively few studies have focused on the protective effects of ALI. This study aimed to determine the potential role of miR-21 in sepsis-induced ALI. Methods: We performed quantitative real-time polymerase chain reaction in a septic mouse model induced by cecal ligation and puncture (CLP) and found that miR-21 expression was upregulated. We then transfected the miR-21 precursor to upregulate miR-21 expression and miR-21 inhibitor to downregulate miR-21 expression. The sham group was exposed only to the cecum. ALI was induced by CLP, and the pre-miR-21+ALI and anti-miR-21+ALI groups were treated with miR-21 precursor or miR-21 inhibitor in the caudal vein before CLP. Pre-miR-21+ALI+PTEN inhibition (Pre-miR-21+ALI+PI) and anti-miR-21+ALI+PTEN inhibition (Anti-miR-21+ALI+PI) groups were treated with PTEN inhibition into the caudal vein after miR-21 transfection. Inflammatory cytokines, oxidative stress indicators, lung tissue cell apoptosis, oxygenation index (OI), lung wet/dry weight ratio, and lung pathological changes in the lung were observed in each group. Results: Compared with ALI mice, inflammatory response, oxidative stress indicators, lung tissue cell apoptosis, and the degree of lung injury were remarkably alleviated in Pre-miR-21+ALI mice and aggravated in Anti-miR-21+ALI mice. Western blot analysis showed that phosphatase and tensin homolog (PTEN) protein expression was decreased in CLP-treated mics. PTEN protein expression was decreased in the Pre-miR-21+ALI group but increased in the Anti-miR-21+ALI group. Moreover, the effect of miR-21 on anti-inflammatory, anti-oxidative stress, and anti-apoptosis enhanced after PTEN inhibition. Conclusion: This study revealed that miR-21 has a protective effect in sepsis-induced ALI by regulating PTEN in mice.

Abstract
Sepsis is resulted from a systemic inflammatory response to bacterial, viral, or fungal agents. The induced inflammatory response by these microorganisms can lead to multiple organ system failure with devastating consequences. Recent studies have shown altered expressions of several non-coding RNAs such as long non-coding RNAs (lncRNAs), microRNAs (miRNAs) and circular RNAs (circRNAs) during sepsis. These transcripts have also been found to participate in the pathogenesis of multiple organ system failure through different mechanisms. NEAT1, MALAT1, THRIL, XIST, MIAT and TUG1 are among lncRNAs that participate in the pathoetiology of sepsis-related complications. miR-21, miR-155, miR-15a-5p, miR-494-3p, miR-218, miR-122, miR-208a-5p, miR-328 and miR-218 are examples of miRNAs participating in these complications. Finally, tens of circRNAs such as circC3P1, hsa_circRNA_104484, hsa_circRNA_104670 and circVMA21 and circ-PRKCI have been found to affect pathogenesis of sepsis. In the current review, we describe the role of these three classes of noncoding RNAs in the pathoetiology of sepsis-related complications.

Abstract
OBJECTIVE Some reports have suggested the involvement of microRNA-24-3p (miR-24-3p) in heart diseases. Here, the intention of this work was to unmask whether miR-24-3p from M2 macrophages-derived exosomes (M2-exo) could protect against myocardial injury after sepsis. METHODS Mice model of sepsis was induced by intraperitoneal injection of lipopolysaccharide (LPS). miR-24-3p and tumor necrosis factor superfamily member 10 (Tnfsf10) expression levels were measured in the myocardial tissue of septic mice. M2-exo were isolated, in which miR-24-3p expression was altered. Then, septic mice were alone or in combination injected with the miR-24-3p-modified M2-exo or siRNA of Tnfsf10. Subsequently, cardiac function, apoptosis and serum inflammatory response were examined. RESULTS miR-24-3p expression dropped while Tnfsf10 expression raised in the myocardial tissue of septic mice. M2-exo-derived miR-24-3p or deficiency of Tnfsf10 had cardioprotective effects on LPS-induced myocardial injury in mice through improving cardiac function and reducing cardiomyocyte apoptosis in the myocardial tissue and serum inflammation. A binding relation exhibited between miR-24-3p and Tnfsf10, and M2-exo-derived miR-24-3p alleviated LPS-induced myocardial injury by inhibiting Tnfsf10. CONCLUSION Up-regulating miR-24-3p from M2-exo imposes cardioprotection against myocardial injury after sepsis through reducing Tnfsf10 expression.

Abstract
Our study aimed at studying mechanism of miR-214 packaged with lipidosome nanoparticles on prompting apoptosis of intestinal cancer through regulating p53 pathway. SW480 cells were divided into blank group, empty carrier group, agonist group and group with carrier and antagonist. The negative control group was set, and groups related to p53 pathway were set as agonist group, inhibitor group and group with antagonist and inhibitor. The effect of miR-214 packaged with lipidosome nanoparticles on proliferation and apoptosis of intestinal cancer cells and p53 pathway in intestinal cancer cells was observed. Expression level of miR-214 in group with carrier and antagonist was lower than in other groups. The proportion of active cells in the group with carrier and antagonist started to be reduced notably from the second day. There was no notable declining tendency active cells' proportion from other groups. The quantity of cell apoptosis in group with carrier and antagonist was higher than in the other groups. The expression level of cleaved Caspase-3 in the group with carrier and antagonist was notably higher than in the other groups. Moreover, expression of Bcl-2/Bax protein was reversed, while expression of p53 protein in the carrier and antagonist groups was notably higher than in the other groups. The antagonist of miR-214 packaged with lipidosome nanoparticles could target on p53 pathway. The activity of p53 pathway was reduced by miR-214, and expression of Bcl-2 was increased. The expressions levels of Bax and cleaved Caspase-3 were also reversed, and molecular mechanism was mainly related with restraining of p53 signal pathway.

Abstract
Sepsis-induced myocardial dysfunction (SIMD) is ubiquitous in septic shock patients and is associated with high morbidity and mortality rates. Heat shock protein 22 (Hsp22), which belongs to the small HSP family of proteins, is involved in several biological functions. However, the function of Hsp22 in lipopolysaccharide (LPS)-induced myocardial injury is not yet established. This study was aimed at investigating the underlying mechanistic aspects of Hsp22 in myocardial injury induced by LPS. In this study, following the random assignment of male C57BL/6 mice into control, LPS-treated, and LPS + Hsp22 treated groups, relevant echocardiograms and staining were performed to scrutinize the cardiac pathology. Plausible mechanisms were proposed based on the findings of the enzyme-linked immunosorbent assay and Western blotting assay. A protective role of Hsp22 against LPS-induced myocardial injury emerged, as evidenced from decreased levels of creatinine kinase-MB (CK-MB), lactate dehydrogenase (LDH), and enhanced cardiac function. The post-LPS administration-caused spike in inflammatory cytokines (IL-1β, IL-6, TNF-α and NLRP3) was attenuated by the Hsp22 pre-treatment. In addition, superoxide dismutase (SOD) activity and B-cell lymphoma-2 (Bcl2) levels were augmented by Hsp22 treatment resulting in lowering of LPS-induced oxidative stress and cardiomyocyte apoptosis. In summary, the suppression of LPS-induced myocardial injury by Hsp22 overexpression via targeting of inflammation, oxidative stress, and apoptosis in cardiomyocytes paves the way for this protein to be employed in the therapy of SIMD.

Abstract
Myocardial injury (MI) is a common complication of sepsis. MicroRNAs (miRNAs) have been suggested as potential biomarkers of MI; however, their mechanisms in sepsis-induced MI remain unclear. A sepsis rat model was constructed by use of cecal ligation and puncture (CLP). The levels of miR-195-5p and activating transcription factor 6 (ATF6) expression were determined by quantitative reverse-transcription polymerase chain reaction, and cytokine levels were detected by ELISA. The levels of oxidative stress (OS)-related indicators and endoplasmic reticulum stress (ERS)-related proteins were examined, and the regulatory effect of miR-195-5p on ATF6 was determined by using the luciferase reporter assay. Our results showed that miR-195-5p expression was downregulated and ATF6 expression was upregulated in lipopolysaccharide-induced cardiomyocytes and mice with CLP-induced sepsis. We also found that miR-195-5p could markedly attenuate the inflammation, apoptosis, OS, and ERS associated with sepsis-induced MI. Additionally, we verified that miR-195-5p could relieve sepsis-induced MI by targeting ATF6. This study identified potential targets for treating MI after sepsis.

Abstract
Septicemia is associated with excessive inflammation, oxidative stress and apoptosis, causing myocardial injury that results in high mortality and disability rates worldwide. The abnormal expression of multiple microRNAs (miRNAs/miRs) is associated with more severe sepsis‑induced myocardial injury (SIMI) and miR‑335 has been shown to protect cardiomyocytes from oxidative stress. The present study aimed to investigate the role of miR‑335 in SIMI. An SIMI model was established by cecal ligation and puncture (CLP) in mice. An miRNA‑335 precursor (pre‑miR‑335) was transfected to accelerate miR‑335 expression and an miR‑335 inhibitor (anti‑miR‑335) was used to inhibit miR‑335 expression. CLP or sham surgery was performed on pre‑miR‑335, anti‑miR‑335 and wild‑type mice and miR‑335 expression was determined by reverse transcription‑quantitative PCR. Inflammatory factors (TNF‑α, IL‑6 and IL‑10) and troponin (cTNI), brain natriuretic peptide (BNP), creatine kinase (CK), lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) were assessed using commercial kits. Apoptosis was detected by flow cytometry and cardiac function was assessed using a Langendorff isolated cardiac perfusion system. miR‑335 expression was upregulated and an elevation in inflammatory factors and cTNI, BNP, CK, LDH and AST was observed. Compared with the wild‑type control group, pre‑miR‑335 mice treated with CLP exhibited significantly reduced left ventricular development pressure, maximum pressure increased reduction rates, as well as decreased levels of TNF‑α, IL‑6 and IL‑10, myocardial injury and apoptosis; by contrast, these features were amplified in CLP‑treated anti‑miR‑335 mice. In conclusion, the upregulation of miR‑335 exerted ameliorative effects on myocardial injury following sepsis and may indicate a novel therapeutic intervention for SIMI.

Abstract
BACKGROUND Myocardial dysfunction caused by sepsis (SIMD) leads to high mortality in critically ill patients. We investigated the function and mechanism of long non-coding RNA MAPKAPK5-AS1 (lncRNA MAPKAPK-AS1) on lipopolysaccharide (LPS)-induced inflammation response in vivo and in vitro. METHOD Male SD rats were utilized for in vivo experiments. Rat cardiomyocytes (H9C2) were employed for in vitro experiments. Western blotting was employed to measure protein expression, and RT-PCR was performed to measure mRNA expression of inflammation factors. TUNEL and flow cytometry were carried out to evulate cell apoptosis. RESULT The results showed that the expression of MAPKAPK5-AS1 was increased, while the expression of miR-124-3p was decreased in the inflammatory damage induced by LPS in vivo and in vitro. Knockdown of MAPKAPK5-AS1 reduced LPS-induced cell apoptosis and inflammation response, while overexpression of miR-124-3p weakened the effects of MAPKAPK5-AS1 knockdown on LPS-induced cell apoptosis and inflammation response. Moreover, miR-124-3p was identified as a downstream miRNA of MAPKAPK5-AS1, and E2F3 was a target of miR-214-3p. MAPKAPK5-AS1 knockdown increased the expression of miR-124-3p, while miR-124-3p overexpression reduced the expression of MAPKAPK5-AS1. In addition, miR-124-3p was found to downregulate E2F3 expression in H9C2 cells. CONCLUSION MAPKAPK5-AS1/miR-124-3p/E2F3 axis regulates LPS-related H9C2 cell apoptosis and inflammatory response.

Abstract
The mechanisms occurring during sepsis that produce an increased risk of cardiovascular (CV) disease (CVD) are poorly understood. Even less information exists regarding CV dysfunction as a complication of sepsis, particularly for sepsis-induced cardiomyopathy. However, recent research has demonstrated that non-coding RNAs, including microRNAs, long non-coding RNAs, and circular RNAs, play a crucial role in genetic reprogramming, gene regulation, and inflammation during the development of CVD. Here we describe experimental findings showing the importance of non-coding RNAs mediating relevant mechanisms underlying CV dysfunction after sepsis, so contributing to sepsis-induced cardiomyopathy. Importantly, non-coding RNAs are critical novel regulators of CVD risk factors. Thus, they are potential candidates to improve diagnostics and prognosis of sepsis-induced cardiomyopathy and other CVD events occurring after sepsis and set the basis to design novel therapeutic strategies.

Ther Clin Risk Manag 2021; 17:563-570. [PMID: 34113113 PMCID: PMC8185456 DOI: 10.2147/tcrm.s309800] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 05/05/2021] [Indexed: 02/05/2023] Open
Abstract
Objective To investigate the diagnostic value of plasma miRNA-497, cardiac troponin I (cTnI), fatty acid binding protein 3 (FABP3), glycogen phosphorylase isoenzyme BB (GPBB) in pediatric sepsis complicated with myocardial injury. Methods From August 2018 to February 2020, 82 children with sepsis admitted to our hospital and 50 health children who came for physical examination (defined as control group) were enrolled in this study. Children with sepsis and myocardial injury were enrolled in the combined group (n=35), and those without myocardial injury were enrolled in the sepsis group (n=47). General data of three groups were collected, and the levels of miRNA-497, FABP3, GPBB, creatine kinase isoenzyme MB (CK-MB), procalcitonin (PCT), C-reactive protein (CRP), cTnI and N-terminal pro-B-type natriuretic peptide (NT-proBNP) were detected and the cardiac function was measured. The diagnostic value of plasma miRNA-497, cTnI, FABP3 and GPBB in pediatric sepsis complicated with myocardial injury was analyzed. Results The infection site of the combined group was not significantly different from that of the sepsis group. The levels of miRNA-497, FABP3, GPBB, CK-MB, PCT, CRP, cTnI, NT-proBNP in the combined group were all higher than those in the sepsis group and the control group (P<0.05), and the left ventricular ejection fraction (LVEF) in the combined group was significantly lower than that in the other two group (P<0.05). The area under the curve (AUC) of the combination of miRNA-497, FABP3, GPBB, and cTnI in the diagnosis of sepsis complicated with myocardial injury was significantly higher than that of CK-MB, PCT, CRP, NT-proBNP alone (P<0.05), but there was no significant difference when compared with miRNA-497, FABP3, GPBB and cTnI alone (P>0.05). When the optimal thresholds of miRNA-497, FABP3, GPBB, and cTnI were set to 2.03, 6.23ng/mL, 4.01ng/mL, 1.23ng/mL, respectively, the sensitivity was 95.65%, 88.89%, 82.61%, 87.50%, respectively; the specificity was 83.33%, 94.12%, 83.33%, 90.91%, respectively; and the accuracy was 91.43%, 91.43%, 82.86%, 88.57%, respectively. Pearson correlation analysis indicating that miRNA-497 was positively correlated with the levels of FABP3, GPBB, and cTnI in the combined group (r=0.821, 0.621, 0.782, P<0.05). Conclusion Plasma miRNA-497, cTnI, FABP3, and GPBB levels were increased in pediatric sepsis complicated with myocardial injury, and their combination had high diagnostic value, which was of great clinical significance for early diagnosis and early treatment of pediatric sepsis complicated with myocardial injury.

Abstract
BACKGROUND AND PURPOSE Sepsis is a severe infection-induced disease with multiple organ failure, and sepsis-induced cardiomyopathy is a fatal condition. Inflammatory response and oxidative stress are reported to be involved in the development of sepsis-induced cardiomyopathy. Dulaglutide is a novel antidiabetic agent that is currently reported to exert an anti-inflammatory effect. The present study aims to explore the potential protective property of dulaglutide on lipopolysaccharide (LPS)-induced injury on cardiomyocytes. METHODS LPS was used to induce an in vitro injury model on cardiomyocytes. The mitochondrial reactive oxygen species (ROS) level was detected using MitoSOX red, and reduced glutathione (GSH) was measured to evaluate the status of oxidative stress in H9c2 myocardial cells. The expressions of NADPH oxidase-1 (NOX-1) and inducible nitric oxidesynthase (iNOS) were determined using real-time PCR and western blot analysis. Real-time PCR and enzyme-linked immunosorbent assay (ELISA) were both used to detect the expressions and concentrations of tumor necrosis factor-α, interleukin-1β, interleukin-17, matrix metalloproteinase-2, and matrix metalloproteinase-9 in H9c2 myocardial cells, respectively. The production of nitric oxide (NO) was measured using the Griess reagent. The levels of creatine kinase isoenzyme-MB (CK-MB) and cardiac troponin I (cTnI) were detected using ELISA. Western blot was utilized to determine the expressions of toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and p-NF-κB p65 in H9c2 myocardial cells in the nucleus. RESULTS First, dulaglutide ameliorated LPS-induced oxidative stress by suppressing the production of mitochondrial ROS and elevating the level of reduced GSH, as well as downregulating NOX-1. Second, the LPS-induced cardiomyocyte injury was alleviated by dulaglutide through downregulating CK-MB and cTnI, accompanied by inhibiting iNOS expression and NO production. Lastly, the production of inflammatory factors and upregulation of MMPs induced by LPS were both significantly reversed by dulaglutide through suppressing the TLR4/Myd88/NF-κB signaling pathway. CONCLUSIONS Dulaglutide alleviated LPS-induced injury in cardiomyocytes by inhibiting inflammation and oxidative stress.

Abstract
Purpose The present study explored the potential therapeutic role of oleuropein in
sepsis-induced heart injury along with the role of GSK-3β/NF-kB signaling
pathway. Methods Sepsis-induced myocardial injury was induced by cecal ligation and puncture
(CLP) in rats. The cardiac injury was assessed by measuring the levels of
cTnI and creatine kinase-MB (CK-MB). Sepsis-induced inflammation was
assessed by measuring interleukin-6 (IL-6), IL-10 and HMGB1 levels. The
different doses of oleuropein (5, 10, and 20 mg/kg) were given prior to CLP.
Oleuropein (20 mg/kg) was administered after 6 hof CLP. The expressions of
GSK-3β, p-GSK-3β (Ser9) and nuclear factor-κB (NF-κB) were measured in heart
homogenates. Results Cecal ligation and puncture was associated with myocardial injury, an
increase in IL-6, a decrease in IL-10 and an increase in HMGB1. Moreover, it
decreased the ratio of p-GSK-3β/GSK-3β and increased the expression of
p-NF-kB. Pretreatment with oleuropein attenuated CLP-induced myocardial
injury and systemic inflammation in a dose-dependent manner. Administration
of oleuropein after the onset of CLP also attenuated cardiac injury and
inflammation. It also restored CLP-induced changes in the HMGB1 levels, the
ratio of p-GSK-3β/GSK-3β and expression of p- NF-kB. Conclusions Oleuropein attenuates sepsis-induced systemic inflammation and myocardial
injury by inhibiting NF-kB and GSK-3β signaling.

MicroRNA-23a reduces lipopolysaccharide-induced cellular apoptosis and inflammatory cytokine production through Rho-associated kinase 1/sirtuin-1/nuclear factor-kappa B crosstalk. Chin Med J (Engl) 2021; 134:829-839.

Abstract
Background: MicroRNAs are closely associated with the progression and outcomes of multiple human diseases, including sepsis. In this study, we examined the role of miR-23a in septic injury. Methods: Lipopolysaccharide (LPS) was used to induce sepsis in a rat model and H9C2 and HK-2 cells. miR-23a expression was evaluated in rat myocardial and kidney tissues, as well as H9C2 and HK-2 cells. A miR-23a mimic was introduced into cells to identify the role of miR-23a in cell viability, apoptosis, and the secretion of inflammatory cytokines. Furthermore, the effect of Rho-associated kinase 1 (ROCK1), a miR-23a target, on cell damage was evaluated, and molecules involved in the underlying mechanism were identified. Results: In the rat model, miR-23a was poorly expressed in myocardial (sham vs. sepsis 1.00 ± 0.06 vs. 0.27 ± 0.03, P < 0.01) and kidney tissues (sham vs. sepsis 0.27 ± 0.03 vs. 1.00 ± 0.06, P < 0.01). Artificial overexpression of miR-23a resulted in increased proliferative activity (DNA replication rate: Control vs. LPS vs. LPS + Mock vs. LPS + miR-23a: H9C2 cells: 34.13 ± 3.12 vs. 12.94 ± 1.21 vs. 13.31 ± 1.43 vs. 22.94 ± 2.26, P < 0.05; HK-2 cells: 15.17 ± 1.43 vs. 34.52 ± 3.46 vs. 35.19 ± 3.12 vs. 19.87 ± 1.52, P < 0.05), decreased cell apoptosis (Control vs. LPS vs. LPS + Mock vs. LPS + miR-23a: H9C2 cells: 11.39 ± 1.04 vs. 32.57 ± 2.29 vs. 33.08 ± 3.12 vs. 21.63 ± 2.35, P < 0.05; HK-2 cells: 15.17 ± 1.43 vs. 34.52 ± 3.46 vs. 35.19 ± 3.12 vs. 19.87 ± 1.52, P < 0.05), and decreased production of inflammatory cytokines, including interleukin-6 (Control vs. LPS vs. LPS + Mock vs. LPS + miR-23a: H9C2 cells: 59.61 ± 5.14 vs. 113.54 ± 12.30 vs. 116.51 ± 10.69 vs. 87.69 ± 2.97 ng/mL; P < 0.05, F = 12.67, HK-2 cells: 68.12 ± 6.44 vs. 139.65 ± 16.62 vs. 143.51 ± 13.64 vs. 100.82 ± 9.74 ng/mL, P < 0.05, F = 9.83) and tumor necrosis factor-α (Control vs. LPS vs. LPS + Mock vs. LPS + miR-23a: H9C2 cells: 103.20 ± 10.31 vs. 169.67 ± 18.84 vs. 173.61 ± 15.91 vs. 133.36 ± 12.32 ng/mL, P < 0.05, F = 12.67, HK-2 cells: 132.51 ± 13.37 vs. 187.47 ± 16.74 vs. 143.51 ± 13.64 vs. 155.79 ± 15.31 ng/mL, P < 0.05, F = 9.83) in cells. However, ROCK1 was identified as a miR-23a target, and further up-regulation of ROCK1 mitigated the protective function of miR-23a in LPS-treated H9C2 and HK-2 cells. Moreover, ROCK1 suppressed sirtuin-1 (SIRT1) expression to promote the phosphorylation of nuclear factor-kappa B (NF-κB) p65, indicating the possible involvement of this signaling pathway in miR-23a-mediated events. Conclusion: Our results indicate that miR-23a could suppress LPS-induced cell damage and inflammatory cytokine secretion by binding to ROCK1, mediated through the potential participation of the SIRT1/NF-κB signaling pathway.

Abstract
Sepsis is a severe condition characterized by systemic inflammation. One of the most involved organs in sepsis is the heart. On the other hand, heart failure and dysfunction are some of the most leading causes of death in septic patients. miRNAs are short single-strand non-coding ribonucleic acids involved in the regulation of gene expression on a post-transcriptional phase, which means they are a part of the epigenetic process. Recently, researchers have found that miRNA expression in tissues and blood differs depending on different conditions. Because of this property, their use as serum sepsis biomarkers has also been explored. A narrative review is carried out to gather and summarize what is known about miRNAs' influence on cardiac dysfunction during sepsis. When reviewing the literature, we found at least 77 miRNAs involved in cardiac inflammation and dysfunction during sepsis. In the future, miRNAs may be used as early sepsis-induced cardiac dysfunction biomarkers or as new drug targets. This could help clinicians to early detect, prevent, and treat cardiac damage. The potential role of miRNAs as new diagnostic tools and therapeutic strategies worth deepening the complex network between non-coding RNA and biological pathways. Additional studies are needed to further investigate their role in sepsis-induced myocardium injury.

Abstract
Background The oncogenic role of the newly identified lncRNA LUADT1 has been revealed in lung adenocarcinoma. It was reported that LUADT1 plays a critical role in multiple human diseases. This study was carried out to investigate the role of LUADT1 in sepsis. Methods Sixty patients with sepsis and sixty healthy volunteers were recruited for this study. Plasma samples were collected from all participants. Human primary coronary artery endothelial cells were also used in this study. The expression of Pim-1, miR-195 and LUADT1 were detected by RT-qPCR. The interaction between miR-195 and LUADT1 was determined by overexpression experiments and luciferase activity assay. Cell apoptosis was detected by flow cytometry. The expression of apoptosis-related protein was detected by Western blotting. Results Bioinformatics analysis revealed the potential interaction between LUADT1 and miR-195, which was confirmed by dual luciferase reporter assay. LUADT1 was downregulated in patients with sepsis. Moreover, LPS treatment downregulated the expression of LUADT1 in primary cardiac endothelial cells. Overexpression of LUADT1 and miR-195 did not affect the expression of each other in primary cardiac endothelial cells. Interestingly, overexpression of LUADT1 was found to upregulate the expression of Pim-1, a target of miR-195. In addition, it was found that overexpression of LUADT1 and Pim-1 reduced the enhancement effects of miR-195 on LPS-induced cardiac endothelial cell apoptosis. Conclusion In summary, LUADT1 may protect cardiac endothelial cells against apoptosis in sepsis by regulating the miR-195/Pim-1 axis.

Abstract
Fifteen percent third-degree burn rat model was used to identify miRNAs that are markers of burn injury-induced myocardial damage. Cardiac tissues were evaluated to determine miRNA profile sequencing. Pearson's correlation analysis was used between miRNAs and injury markers. ROC curve analysis was used to estimate miRNA's sensitivity and specificity for the diagnosis of myocardial damage caused by burn injury. The sequencing analysis revealed 23 differentially expressed miRNAs. Pearson's correlation analysis revealed that rno-miR-190b-3p and C5b9, rno-miR-341, rno-miR-344b-3p and TnI, rno-miR-344b-3p and CK-MB were significantly positively correlated, respectively. ROC curve analysis demonstrated that rno-miR-341, rno-miR-344b-3p, and rno-miR-190b-3p exhibited high sensitivity and specificity for the diagnosis of myocardial damage caused by burn injury. In conclusion, our results suggest that rno-miR-341, rno-miR-344b-3p, and rno-miR-190b-3p have the potential to be used as sensitive and specific biomarkers to diagnose myocardial damage caused by burn injury.

Abstract
Background: Uric acid (UA) has been reported to be an important risk factor for cardiovascular diseases and can cause endothelial cell apoptosis through unclear mechanisms. Accumulating evidence has demonstrated that miR-214 plays a pivotal role in the pathogenesis of cardiovascular diseases. This study was to investigate the role of miR-214 in UA-induced endothelial cell apoptosis and the underlying mechanism. Material and methods: We enrolled 30 patients with hyperuricemia and 32 healthy controls and analyzed the levels of miR-214 in the serum of the participants. Then mouse aorta endothelial cells (MAECs) were treated with UA to induce cell apoptosis. An miR-214 mimic and a specific COX-2 inhibitor (NS398) were used to confirm the roles of these molecules in mediating UA-induced MAEC apoptosis or COX-2/PGE2 cascade activation. Results: A significant reduction in circulating miR-214 in the hyperuricemia patients compared with the healthy controls, along with a negative correlation with UA levels was observed. In the MAECs, UA treatment strikingly increased apoptosis as shown by the upregulation of BAX and cleaved Caspase-3 and the increased number of apoptotic cells. Interestingly, the expression of COX-2 was also upregulated at both the protein and mRNA levels during UA-induced cell apoptosis. In addition, an miR-214 mimic blocked UA-induced MAEC apoptosis, COX-2 induction and PGE2 secretion. The inhibition of COX-2 markedly ameliorated UA-induced apoptotic response and PGE2 production in MAECs. Luciferase activity assays further confirmed that COX-2 is a target gene of miR-214 in endothelial cells. Conclusion: We concluded that miR-214 could alleviate UA-induced MAEC apoptosis possibly by inhibiting the COX-2/PGE2 cascade.

miR-214-3p Attenuates Sepsis-Induced Myocardial Dysfunction in Mice by Inhibiting Autophagy through PTEN/AKT/mTOR Pathway. BIOMED RESEARCH INTERNATIONAL 2020; 2020:1409038. [PMID: 32714974 PMCID: PMC7359738 DOI: 10.1155/2020/1409038] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Accepted: 06/16/2020] [Indexed: 12/17/2022]
Abstract
Aims. More than half of the patients with sepsis would develop cardiac dysfunction, which is termed as sepsis-induced myocardial dysfunction (SIMD). Previous studies suggest that autophagy may play an important role in SIMD. The present study investigated whether miR-214-3p could attenuate SIMD by inhibiting autophagy. Main Methods. In this article, we investigated the role of autophagy in a mouse model of cecal ligation and puncture (CLP). The structure and function of hearts harvested from the mice were evaluated. Myocardial autophagy levels were detected with immunohistochemical, immunofluorescent, and Western blot. Key Findings. miR-214-3p can alleviate SIMD in septic mice by inhibiting the level of cardiac autophagy to attenuate myocardial dysfunction. Moreover, this study showed that miR-214-3p inhibited autophagy by silencing PTEN expression in the myocardial tissues of septic mice. Significance. This study showed that miR-214-3p attenuated SIMD through myocardial autophagy inhibition by silencing PTEN expression and activating the AKT/mTOR pathway. The present findings supported that miR-214-3p may be a potential therapeutic target for SIMD.

Abstract
BACKGROUND Ischemic preconditioning (IPC) and remote ischemic preconditioning (RIPC) protect myocardial tissue against subsequent ischemia and reperfusion injury (IRI) and have a high potential to improve patient outcome. The mediators and mechanisms of protection through IPC and RIPC remain largely unknown, but micro-RNAs (miRNAs) are promising candidates. METHODS Systematic review of Medline and Embase databases for biomedical scientific literature. RESULTS A total of 26 relevant publications (21 full-text original articles and 5 conference abstracts) were identified, 8 describing cell culture experiments, 14 animal experiments, and 4 randomized clinical trials in humans. Most commonly reported miRNAs with differential expression between preconditioned and control groups include miR-1, miR-21, and miR-144. Experimental designs and procedures differ widely, thereby limiting the potential to compare results between studies. Two of the four RCTs did not find any differentially expressed miRNAs. CONCLUSIONS Results from RCTs should feed back into basic research and focused studies confirming or rejecting hypotheses generated by these RCTs are needed.

Gracillin inhibits apoptosis and inflammation induced by lipopolysaccharide (LPS) to alleviate cardiac injury in mice via improving miR-29a. Biochem Biophys Res Commun 2020; 523:580-587.

Abstract
Sepsis induces critical myocardial dysfunction, resulting in an increased mortality. Gracillin (GRA) is a natural steroidal saponin, showing strong capacities of anti-inflammation, but its pharmacological effects on lipopolysaccharide (LPS)-induced acute cardiac injury still remain unclear. In this study, we attempted to explore if GRA was effective to attenuate cardiac injury in LPS-challenged mice and the underlying mechanisms. First, we found that GRA treatments markedly up-regulated the expression of miR-29a in cardiomyocytes. LPS-induced cytotoxicity in cardiomyocytes was significantly alleviated by GRA treatment, as evidenced by the improved cell viability and reduced lactate dehydrogenase (LDH) release. In addition, LPS-triggered apoptotic cell death was clearly ameliorated in cardiomyocytes co-treated with GRA. Notably, LPS-exposed cells showed significantly reduced expression of miR-29a, while being rescued by GRA treatment. In vivo, LPS apparently impaired cardiac function in mice, which was, however, alleviated by GRA administration. In addition, GRA markedly attenuated apoptosis in hearts of LPS-challenged mice by decreasing the expression of cleaved Caspase-3. LPS-triggered inflammatory response in cardiac tissues was also suppressed by GRA through blocking nuclear factor κB (NF-κB) signaling pathway. We also found that miR-29a expression was highly reduced in hearts of LPS-treated mice but was rescued by GRA pretreatment. Besides, miR-29a mimic alleviated LPS-induced apoptosis and inflammation in cardiomyocytes; however, LPS-caused effects were further accelerated by miR-29a. Of note, the protective effects of GRA on LPS-injured cardiac tissues were significantly abrogated by miR-29a suppression. In conclusion, our findings demonstrated that GRA exerted an effective role against LPS-induced acute cardiac injury through impeding apoptosis and inflammation regulated by miR-29a.

Abstract
Myocardial cell injury or cardiomyopathy is associated with excessive inflammatory response and apoptosis of cardiac myocytes during sepsis. MicroRNA-23b (miR-23b) is a multifunctional miRNA that is considered to regulate immunosuppression in sepsis. The aim of this study was to examine the effect of miR-23b on cardiomyopathy induced by sepsis and to explore the potential mechanism involved. Sprague-Dawley rats were subjected to cecal ligation and puncture (CLP), and the level of miR-23b at different time points was measured by quantitative real-time polymerase chain reaction (qPCR). Then, we overexpressed miR-23b in vivo and in vitro. The rats were subjected to CLP 7 days after transfection. Cardiac function, inflammatory response, and heart tissues were examined 3 days thereafter. In an in vitro experiment, H9C2 cardiomyoblasts were stimulated with lipopolysaccharide (LPS) after transfection of miR-23b, following which apoptosis and the level of NF-κB were analyzed. The expression of miR-23b was upregulated during polymicrobial sepsis, and transfection of miR-23b lentivirus improved the outcome of sepsis-induced cardiomyopathy by attenuating inflammatory responses and protecting against histopathological damage. In in vitro experiments, elevated miR-23b inhibited excessive apoptosis of cardiomyocytes, which may be because activation of the NF-κB signaling pathway was inhibited by the decreased levels of TRAF6 and IKKβ. Therefore, miR-23b improved sepsis-induced cardiomyopathy by attenuating the inflammatory response, suppressing apoptosis, and preventing NF-κB activation via targeted inhibition of TRAF6 and IκκB. These results indicated that miR-23b may represent a novel therapeutic approach for clinical treatment of sepsis-induced cardiomyopathy.

Abstract
The aim of this study was to evaluate the role of miR-181a-5p in sepsis, and to further explore the molecular mechanism. RAW 264.7 cells were stimulated with 1 μg/ml LPS for 4 hours. Firstly, qRT-PCR and ELISA was adopted to evaluate the expression of miR-181a-5p and p ro-inflammatory cytokines in RAW 264.7 macrophages a fter LPS stimulation. Results showed that pro-inflammatory cytokines and miR-181a-5p were significantly increased after LPS treatment. Then, we identified that sirtuin-1 (SIRT1) was a direct target of miR-181a-5p and it was down-regulated in LPS treated RAW264.7 macrophages. Furthermore, the data suggested that the miR-181a-5p inhibitor significantly inhibited LPS enhanced inflammatory cytokines expression and NF-κB pathway activation, and these changes were eliminated by SIRT1 silencing. Moreover, the role of the miR-181a-5p inhibitor on sepsis was studied in vivo. We found that the miR-181a-5p inhibitor significantly decreased the secretion of inflammatory factors, and the levels of creatine (Cr), blood urea nitrogen (BUN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in a serum for mice with sepsis. However, all the effects were reversed by SIRT1-siRNA. In summary, these results indicated that miR-181a-5p was involved in sepsis through regulating the inflammatory response by targeting SIRT1, suggesting that miR-181a-5p may be a potential target for the treatment of sepsis.

Abstract
BACKGROUND Cardiac dysfunction is a common manifestation of sepsis and is associated with early increases in inflammation and decreases in myocardial protein synthesis. However, little is known regarding the molecular mechanisms regulating protein homeostasis during the recovery phase after the removal of the septic nidus. Therefore, the purpose of this study was to investigate diverse signal transduction pathways that regulate myocardial protein synthesis and degradation. METHODS Adult male C57BL/6 mice were used to identify potential mechanisms mediating the acute (24 h) effect of cecal ligation and puncture as well as long-term changes that manifest during the chronic (10 days) recovery phase. RESULTS Sepsis acutely decreased cardiac protein synthesis that was associated with reduced phosphorylation of S6K1/S6 but not 4E-BP1. Sepsis also decreased proteasome activity, although with no change in MuRF1 and atrogin-1 mRNA expression. Sepsis acutely increased apoptosis (increased caspase-3 and PARP cleavage), autophagosome formation (increased LC3B-II), and canonical inflammasome activity (increased NLRP3, TMS1, cleaved caspase-1). In contrast, during the recovery phase, independent of a difference in food consumption, global protein synthesis was increased, the early repression in proteasome activity was restored to basal levels, whereas stimulation of apoptosis, autophagosome formation, and the canonical inflammasome pathway had abated. However, during recovery there was a selective stimulation of the noncanonical inflammasome pathway as evidenced by activation of caspase-11 with cleavage of Gasdermin D. CONCLUSIONS These data demonstrate a temporally distinct homeostatic shift in the cardiac proteostatic response to acute infection and recovery.

Abstract
It was demonstrated that α1 adrenergic receptor (α1-AR) activation by phenylephrine (PE) attenuated cardiac dysfunction in lipopolysaccharide (LPS)-challenged mice. However, it is unclear whether PE suppresses sepsis-induced cardiomyocyte apoptosis. Here, we investigated the effects of PE on cardiomyocyte apoptosis in LPS-treated adult rat ventricular myocytes (ARVMs) and septic rats induced by cecal ligation and puncture. Cardiomyocyte apoptosis and caspase activity were detected by TUNEL and spectrophotometrical assay, respectively. Bax, Bcl-2 and cytochrome c (Cyt c) levels as well as IκBα, ERK1/2, p38 MAPK, JNK and cardiac troponin I (cTnI) phosphorylation were analyzed by Western blotting, and TNF-α concentration was analyzed by ELISA. PE inhibited LPS-induced caspase-3 activation in ARVMs, which was reversed by prazosin (a membrane permeable α1-AR antagonist), but not by CGP12177A (a membrane impermeable α1-AR antagonist). PE upregulated phosphorylated ERK1/2 and Bcl-2 contents, decreased TNF-α and Bax levels, Cyt c release, caspase-8/-9 activities as well as IκBα, p38MAPK and JNK phosphorylation in LPS-treated ARVMs, all of which were abolished by prazosin. Treatment with U0126 (a specific ERK1/2 inhibitor) reversed the effects of PE on IκBα, p38MAPK and JNK phosphorylation as well as caspase-3/-8/-9 activation in LPS-treated ARVMs. In septic rats, PE not only inhibited myocardial apoptosis as well as IκBα, p38MAPK, and JNK phosphorylation, but also upregulated myocardial phosphorylated ERK1/2. Furthermore, PE inhibited myocardial cTnI phosphorylation and improved cardiac function in septic rats. Taken together, our data suggest that α1-AR activation by PE inhibits sepsis-induced cardiomyocyte apoptosis and cardiac dysfunction via activating ERK1/2 signal pathway.

Abstract
The critical roles of TGFBR2/Smad2 signaling have been established in LPS-induced sepsis, however, the underlying mechanisms by which TGFBR2/Smad2 signaling was regulated in LPS-induced sepsis are still confused. Here, miRNA-based on RNA-sequencing dataset revealed that miR-145 was significantly decreased in human umbilical vein endothelial cells (HUVECs) following LPS treatment. Bioinformatics, luciferase reporter and RNA immune co-precipitation (RIP) assays showed that miR-145 could directly target TGFBR2 and thus inactivated TGFBR2/Smad2 axis. On the contrary, luciferase reporter and chromatin immunoprecipitation (ChIP) analysis showed that Smad2 could directly bind to DNA methyltransferase 1 (DNMT1), the upregulation of which led to miR-145 promoter hypermethylation and downregulation of miR-145 expression, conversely promoting TGFBR2 expression. Notably, knockdown of TGFBR2 partially rescued the inhibition on miR-145 expression induced by LPS treatment. Additionally, we found that knockdown of TGFBR2 or overexpression of miR-145 attenuated LPS-induced sepsis and prolonged the overall survival of septic mice. Furthermore, TGFBR2 overexpression abrogated miR-145 overexpression-mediated attenuation on LPS-induced sepsis. Our results demonstrate the TGFBR2/SMAD2/DNMT1/miR-145 negative regulatory loop is responsible for LPS-induced sepsis.

Abstract
This study aims to explore the roles of miR-145/TGFBR2 axis in sepsis-induced acute lung injury. Here, RNA-sequencing assay showed that miR-145 was significantly decreased in exosomes from sepsis patient blood samples. And miR-145 was decreased but TGFBR2 was increased in LPS-treated mice lung tissues or BEAS-2B cells in a time-dependent manner. Mechanistically, TGFBR2 was identified as a direct target of miR-145 and the downstream effector Smad3 was also suppressed in BEAS-2B cells with miR-145 overexpression. Pre-injection or post-injection of miR-145 agomir following LPS treatment attenuated LPS-induced inflammation, characterized as the downregulation of IL-2 and TNF-α secretion and ameliorate sepsis, and prolonged the overall survival of septic mice with lung injury. Additionally, TGFBR2 overexpression partially abrogated miR-145-mediated inhibition on LPS-induced inflammation and sepsis-induced acute lung injury. Importantly, TGF-β (Transforming growth factor-β) and miR-145 level displayed a negative correlation in sepsis patients. Thus, these results suggest that miR-145 could ameliorate sepsis-induced lung injury via inhibiting TGFBR2 signaling.

Abstract
The aim of the present study was to investigate the role of microRNA (miR)-494-3p in myocardial injury in patients with septic shock and the underlying mechanism. A total of 22 patients with sepsis and 17 patients with septic shock were included in the present study. In addition, 20 healthy subjects were recruited as the control group. Peripheral blood was collected from all subjects and a rat cardiomyocyte model of myocardial injury was constructed. Reverse transcription-quantitative polymerase chain reaction was used to measure miR-494-3p expression, while cell counting kit-8 assays were performed to assess cell proliferation. Flow cytometry was performed to investigate cell cycle distribution and apoptosis. Lactate dehydrogenase (LDH) assays were performed to measure LDH levels. ELISA was also performed to measure LDH, tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels in cell culture supernatants. Western blotting was employed to detect phosphatase and tensin homolog (PTEN) protein expression and dual luciferase reporter assays were performed to identify the interaction between miR-494-3p and PTEN mRNA. Reduced miR-494-3p expression was correlated with myocardial damage in patients with septic shock. Sera from patients with septic shock downregulated miR-494-3p expression in rat cardiomyocytes. miR-494-3p overexpression inhibited rat cardiomyocyte injury induced by treatment with sera from patients with septic shock. Furthermore, miR-494-3p overexpression reduced the synthesis and release of TNF-α and IL-6 from rat cardiomyocytes. PTEN knockdown alleviated rat cardiomyocyte injury following treatment with serum from patients with septic shock. PTEN was demonstrated to induce the release of TNF-α and IL-6 from rat cardiomyocytes treated with septic shock serum, while miR-494-3p was demonstrated to bind to the 3′-untranslated seed region of PTEN mRNA to regulate its expression. The results of the present study suggest that miR-494-3p is downregulated in the peripheral blood of patients with septic shock and is negatively correlated with myocardial injury. The present study also indicates that miR-494-3p regulates PTEN expression, inhibits sepsis-induced myocardial injury and protects the function of cardiomyocytes. The protective effect and mechanism of action of miR-494-3p indicate that it has potential for use in the clinical diagnosis and therapy of myocardial damage.

Abstract
Sepsis-induced skeletal muscle wasting may lead to various severe clinical consequences. Understanding molecular mechanisms of the regulation of the loss of skeletal muscle mass in septic patients remains a significant clinical challenge. The current study was conducted to establish septic mice models to explore the relationship between microRNA (miR)-351 and the transcription element apical (TEA) domain transcription factor (Tead)-4 gene and to investigate its effects on the skeletal muscle through mediating the Hippo signaling pathway in mice with acute sepsis. A total of 60 mice were collected to establish mouse models of acute sepsis. The positive expression rate of Tead-4 and the apoptotic index (AI) were measured. A dual-luciferase reporter gene assay was conducted to verify the targeting relationship between miR-351 and Tead-4. Furthermore, the muscle fiber diameter (MFD) and area (MFA) and the content of 3-methylhistidine (3-MH) and tyrosine (Tyr) were assessed. The expression levels of miR-351, p38-MAPK, Yes-associated protein, Tead-4, B-cell lymphoma X protein (Bax), and Caspase-3 were determined with quantitative RT-PCR and Western blot analysis. Finally, cell viability, apoptosis, and levels of inflammatory factors, including IL-1β, IL-6, IGF-1, TNF-α, and monocyte chemoattractant protein-1 were detected by 3-(4,5-dimethylthiazol-2- yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry, and ELISA. Initially, Tead-4 protein expression was higher in skeletal muscle tissues of mice with acute sepsis. Tead-4 was identified to negatively regulate miR-351. Upregulation of miR-351 increased MFA and MFD, muscle weight water content, Bcl-2 expression levels, and cell viability. Up-regulation of miR-351 reduced AI; 3-MH and Tyr content; positive expression of Tead-4 protein; the expression levels of p38-MAPK, Yap, Tead-4, Bax, and Caspase-3; apoptosis; and inflammatory responses. The current study demonstrated that up-regulation of miR-351 inhibits the degradation of skeletal muscle protein and the atrophy of skeletal muscle in mice with acute sepsis by targeting Tead-4 through suppression of the Hippo signaling pathway. Thus, miR-351 overexpression may be a future therapeutic strategy for acute sepsis.-Zhang, L.-N., Tian, H., Zhou, X.-L., Tian, S.-C., Zhang, X.-H., Wu, T.-J. Upregulation of microRNA-351 exerts protective effects during sepsis by ameliorating skeletal muscle wasting through the Tead-4-mediated blockade of the Hippo signaling pathway.
