Abstract
Myocardial infarction (MI) is a severe heart disease caused by acute, persistent ischemia or hypoxia and finally leads to heart failure and sudden death. However, the intrinsic molecular mechanisms of MI remain largely unknown. lncRNAs have also been implicated in the process of ischemic heart diseases. However, the role of lncRNA TTTY15 in MI is not elucidated. We evaluated the expression of TTTY15 in MI and human cardiomyocyte under hypoxia. We explored the role of TTTY15 in cell injury under hypoxia. We searched for potential target of TTTY15. Up-regulation of TTTY15 was associated with hypoxia. Silencing TTTY15 prevented hypoxia-induced cell apoptosis and rescued the cell migration and invasion. TTTY15 targeted miR-455-5p, which regulated the Jun dimerization protein 2 (JDP2) expression. Knocking down miR-455-5p abolished effects of TTTY-15 silencing on cell injury. Suppression of long noncoding RNA TTTY15 attenuates hypoxia-induced cardiomyocytes injury by targeting miR-455-5p.

Abstract
Serious side effects are plaguing traditional chemotherapy, and the development of drug-free treatment is expected to ease the dilemma. Herein, drug-free polyarginine probes are fabricated from the co-polymerization of arginine monomer and slight amount of rhodamine B monomer, which are efficient for thermoacoustic imaging and therapy with high biocompatibility and safe metabolism. Polyarginine can be strongly pumped upon pulsed microwave irradiation, generating significant thermoacoustic shockwaves, namely thermocavitation, which can in situ destroy mitochondria to initiate programmed cancer cell apoptosis. In vivo explorations demonstrate the high theranostic efficiency for cancer thermoacoustic imaging and cancer inhibition, exhibiting low systemic cytotoxicity and good biocompatibility after systemic administration. Herein, pulsed microwave-pumped biocompatible polyarginine is promising for drug-free precision theranostics without any detectable side effects, and the deep penetration potency of microwave makes it potentially able to treat deep-seated diseases in future biomedicine.

Abstract
BACKGROUND The adult mammalian cardiomyocytes lose their proliferative capacity, which is responsible for cardiac dysfunction and heart failure following injury. The molecular mechanisms underlying the attenuation of adult cardiomyocyte proliferation remain largely unknown. Because long noncoding RNAs (lncRNAs) have a critical role in the development of cardiovascular problems, we investigated whether lncRNAs have any role in the regulation of cardiomyocyte proliferation and cardiac repair. METHODS Using bioinformatics and initial analysis, we identified an lncRNA, named CPR (cardiomyocyte proliferation regulator), that has a potential regulatory role in cardiomyocyte proliferation. For in vivo experiments, we generated CPR knockout and cardiac-specific CPR-overexpressing mice. In isolated cardiomyocytes, we used adenovirus for silencing (CPR-small interfering RNA) or overexpressing CPR. To investigate the mechanisms of CPR function in cardiomyocyte proliferation, we performed various analyses including quantitative reverse transcription-polymerase chain reaction, Western blot, histology, cardiac function (by echocardiography), transcriptome analyses (microarray assay), RNA pull-down assay, and chromatin immunoprecipitation assay. RESULTS CPR level is comparatively higher in the adult heart than in the fetal stage. The silencing of CPR significantly increased cardiomyocyte proliferation in postnatal and adult hearts. Moreover, CPR deletion restored the heart function after myocardial injury, which was evident from increased cardiomyocyte proliferation, improvement of myocardial function, and reduced scar formation. In contrast, the neonatal cardiomyocyte proliferation and cardiac regeneration were remarkably suppressed in CPR-overexpressing mice or adeno-associated virus serotype 9-CPR-overexpressing heart. These results indicate that CPR acts as a negative regulator of cardiomyocyte proliferation and regeneration. Next, we found that CPR targets minichromosome maintenance 3, an initiator of DNA replication and cell cycle progression, to suppress cardiomyocyte proliferation. CPR silenced minichromosome maintenance 3 expression through directly interacting and recruiting DNMT3A to its promoter cysteine-phosphate-guanine sites, as evident from decreased minichromosome maintenance 3 promoter methylation and increased minichromosome maintenance 3 expression in CPR knocked-down cardiomyocytes and CPR knockout mouse heart. These results were confirmed in CPR-overexpressing cardiomyocytes and CPR-overexpressing mouse heart. CONCLUSIONS Together, our findings identified that CPR is a suppressor of cardiomyocyte proliferation and indicated that lncRNAs take part in the regulation of cardiomyocyte proliferation and cardiac repair. Our study provides an lncRNA-based therapeutic strategy for effective cardiac repair and regeneration.

Abstract
Cardiac fibrosis is a pathological remodeling response to myocardial infarction (MI) and impairs cardiac contractility. Long noncoding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is increased in patients with MI. However, the functions of MALAT1 in cardiac fibrosis have not been elucidated. This study elucidates the roles of MALAT1 in MI and the underlying mechanisms. The MI model was established by artificial coronary artery occlusion in mice. Western blot analysis and quantitative reverse transcription-polymerase chain reaction were performed to analyze protein expression and RNA expression, respectively. Cardiac function was measured by echocardiography. Masson's trichrome staining was used to exhibit the fibrotic area in MI hearts. Cardiac fibroblasts were isolated from newborn pups, and cell proliferation was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Upregulation of MALAT1 and downregulation of microRNA-145 (miR-145) were induced in MI heart and angiotensin II (AngII)-treated cardiac fibroblasts, and the inhibition of miR-145 expression was reversed by MALAT1 depletion. Knockdown MALAT1 ameliorated MI-impaired cardiac function and prevented AngII-induced fibroblast proliferation, collagen production, and α-SMA expression in cardiac fibroblasts. MALAT1 stability and transforming growth factor-β1 (TGF-β1) activity were regulated by miR-145. AngII-induced TGF-β1 activity in cardiac fibroblasts was blocked by MALAT1 knockdown. Based on these results, we concluded that lncRNA MALAT1 promotes cardiac fibrosis and deteriorates cardiac function post-MI by regulating TGF-β1 activity via miR-145.

Abstract
Dilated cardiomyopathy (DCM) is a common type of non‑ischemic cardiomyopathy, of which the underlying mechanisms have not yet been fully elucidated. Long noncoding RNAs (lncRNAs) have been reported to serve crucial physiological roles in various cardiac diseases. However, the genome‑wide expression profile of lncRNAs remains to be elucidated in DCM. In the present study, a case‑control study was performed to identify expression deviations in circulating lncRNAs between patients with DCM and controls by RNA sequencing. Partial dysregulated lncRNAs were validated by reverse transcription‑polymerase chain reaction. Gene Ontology, Kyoto Encyclopedia of Genes and Genomes pathway, and lncRNA‑messenger RNA (mRNA) co‑expression network analyses were employed to probe potential functions of these dysregulated lncRNAs in DCM. Comparison between 8 DCM and 8 control samples demonstrated that there were alterations in the expression levels of 988 lncRNAs and 1,418 mRNAs in total. The dysregulated lncRNAs were found to be mainly associated with system development, organ morphogenesis and metabolic regulation in terms of 'biological processes'. Furthermore, the analysis revealed that the gap junction pathway, phagosome, and dilated and hypertrophic cardiomyopathy pathways may serve crucial roles in the development of DCM. The lncRNA‑mRNA co‑expression network also suggested that the target genes of the lncRNAs were different in patients with DCM as compared with those in the controls. In conclusion, the present study revealed the genome‑wide profile of circulating lncRNAs in DCM by RNA sequencing, and explored the potential functions of these lncRNAs in DCM using bioinformatics analysis. These findings provide a theoretical foundation for future studies of lncRNAs in DCM.

Abstract
Cardiovascular diseases (CVDs) affect the heart and the vascular system with a high prevalence and place a huge burden on society as well as the healthcare system. These complex diseases are often the result of multiple genetic and environmental risk factors and pose a great challenge to understanding their etiology and consequences. With the advent of next generation sequencing, many non-coding RNA transcripts, especially long non-coding RNAs (lncRNAs), have been linked to the pathogenesis of CVD. Despite increasing evidence, the proper functional characterization of most of these molecules is still lacking. The exploration of conservation of sequences across related species has been used to functionally annotate protein coding genes. In contrast, the rapid evolutionary turnover and weak sequence conservation of lncRNAs make it difficult to characterize functional homologs for these sequences. Recent studies have tried to explore other dimensions of interspecies conservation to elucidate the functional role of these novel transcripts. In this review, we summarize various methodologies adopted to explore the evolutionary conservation of cardiovascular non-coding RNAs at sequence, secondary structure, syntenic, and expression level.

Abstract
During the past decade numerous studies highlighted the importance of long non-coding RNAs (lncRNAs) in orchestrating cardiovascular cell signaling. Classified only by a transcript size of more than 200 nucleotides and their inability to code for proteins, lncRNAs constitute a heterogeneous group of RNA molecules with versatile functions and interaction partners, thus interfering with numerous endogenous signaling pathways. Intrinsic transcriptional regulation of lncRNAs is not only specific for different cell types or developmental stages, but may also change in response to stress factors or under pathological conditions. Regarding the heart, an increasing number of studies described the critical regulation of lncRNAs in multiple cardiac disorders, underlining their key role in the development and progression of cardiac diseases. In this review article, we will summarize functional cardiac lncRNAs with a detailed view on their molecular mode of action in pathological cardiac remodeling and myocardial infarction. In addition, we will discuss the use of circulating lncRNAs as biomarkers for prognostic and diagnostic purposes and highlight the potential of lncRNAs as a novel class of therapeutic targets for therapeutic purpose in heart diseases.

Abstract
Reactive oxygen species (ROS) are a class of reactive molecules that have been implicated in a variety of cardiovascular diseases, accompanied by disorder of multiple signaling events. As cardiomyocytes maintain abundant of mitochondria, which supply the major source of endogenous ROS, oxidative damage to mitochondria often drives apoptotic cell death and initiates cardiac pathology. In recent years, non-coding RNAs (ncRNAs) have received much attention to uncover their roles in regulating gene expression during those pathological events in the heart, such as myocardial infarction, cardiac hypertrophy, and heart failure. Emerging evidences have highlighted that different ROS levels in response to diverse cardiac stresses result in differential expression of ncRNAs, subsequently altering the expression of pathogenetic genes. However, the knowledge about the ncRNA-linked ROS regulatory mechanisms in cardiac pathologies is still largely unexplored. In this review, we summarize the connections that exist among ROS, ncRNAs, and cardiac diseases to understand the interactions among the molecular entities underlying cardiac pathological events in the hopes of guiding novel therapies for heart diseases in the future.

Abstract
Prohibitin 1 (PHB1) and prohibitin 2 (PHB2) are proteins that are ubiquitously expressed, and are present in the nucleus, cytosol, and mitochondria. Depending on the cellular localization, PHB1 and PHB2 have distinctive functions, but more evidence suggests a critical role within mitochondria. In fact, PHB proteins are highly expressed in cells that heavily depend on mitochondrial function. In mitochondria, these two proteins assemble at the inner membrane to form a supra-macromolecular structure, which works as a scaffold for proteins and lipids regulating mitochondrial metabolism, including bioenergetics, biogenesis, and dynamics in order to determine the cell fate, death, or life. PHB alterations have been found in aging and cancer, as well as neurodegenerative, cardiac, and kidney diseases, in which significant mitochondrial impairments have been observed. The molecular mechanisms by which prohibitins regulate mitochondrial function and their role in pathology are reviewed and discussed herein.

Abstract
AIMS Acute myocardial infarction is one of the most threaten disease in the world. In previous studies, exosome derived miR-126 has been verified that exert an pro-angiogenic function through exosomal transfer. However, the function of miR-126 in ischemic reperfusion injury remains unknown. The aim of the study was to investigate the function and mechanism of miR-126 in ischemic reperfusion injury. METHODS H2O2 and CoCl2-treated neonatal rat ventricular cardiomyocytes were used to analyze the function of miR-126 in vitro. Tunel, JC-1, ROS, LDH and cell survival rates were detected to evaluate the function of miR-126. Rat acute myocardial infarction was performed to elucidate the function of miR-126 in vivo. RESULTS We found that miR-126 could reduce the apoptosis and improved cell survival of H2O2-treated and CoCl2-treated neonatal rat ventricular cardiomyocytes. MiR-126 also attenuates the ROS elevation and mitochondrial membrane potential through JC-1 detection. miR-126 also improved the cardiac function in vivo. Luciferase activity revealed that miR-126 could bind to ERRFI1, suggesting miR-126 functioned through regulating ERRFI1. CONCLUSION We verified the function and mechanism of miR-126 and provide evidence that miR-126 may play important role in ischemic reperfusion injury, and understanding the precise role of miR-126 will undoubtedly shed new light on the clinical treatment.

Comparison of Cardiac miRNA Transcriptomes Induced by Diabetes and Rapamycin Treatment and Identification of a Rapamycin-Associated Cardiac MicroRNA Signature. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2018; 2018:8364608. [PMID: 30647817 PMCID: PMC6311877 DOI: 10.1155/2018/8364608] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/22/2018] [Revised: 08/16/2018] [Accepted: 08/29/2018] [Indexed: 02/07/2023]
Abstract
Rapamycin (Rap), an inhibitor of mTORC1, reduces obesity and improves lifespan in mice. However, hyperglycemia and lipid disorders are adverse side effects in patients receiving Rap treatment. We previously reported that diabetes induces pansuppression of cardiac cytokines in Zucker obese rats (ZO-C). Rap treatment (750 μg/kg/day for 12 weeks) reduced their obesity and cardiac fibrosis significantly; however, it increased their hyperglycemia and did not improve their cardiac diastolic parameters. Moreover, Rap treatment of healthy Zucker lean rats (ZL-C) induced cardiac fibrosis. Rap-induced changes in ZL-C's cardiac cytokine profile shared similarities with that of diabetes-induced ZO-C. Therefore, we hypothesized that the cardiac microRNA transcriptome induced by diabetes and Rap treatment could share similarities. Here, we compared the cardiac miRNA transcriptome of ZL-C to ZO-C, Rap-treated ZL (ZL-Rap), and ZO (ZO-Rap). We report that 80% of diabetes-induced miRNA transcriptome (40 differentially expressed miRNAs by minimum 1.5-fold in ZO-C versus ZL-C; p ≤ 0.05) is similar to 47% of Rap-induced miRNA transcriptome in ZL (68 differentially expressed miRNAs by minimum 1.5-fold in ZL-Rap versus ZL-C; p ≤ 0.05). This remarkable similarity between diabetes-induced and Rap-induced cardiac microRNA transcriptome underscores the role of miRNAs in Rap-induced insulin resistance. We also show that Rap treatment altered the expression of the same 17 miRNAs in ZL and ZO hearts indicating that these 17 miRNAs comprise a unique Rap-induced cardiac miRNA signature. Interestingly, only four miRNAs were significantly differentially expressed between ZO-C and ZO-Rap, indicating that, unlike the nondiabetic heart, Rap did not substantially change the miRNA transcriptome in the diabetic heart. In silico analyses showed that (a) mRNA-miRNA interactions exist between differentially expressed cardiac cytokines and miRNAs, (b) human orthologs of rat miRNAs that are strongly correlated with cardiac fibrosis may modulate profibrotic TGF-β signaling, and (c) changes in miRNA transcriptome caused by diabetes or Rap treatment include cardioprotective miRNAs indicating a concurrent activation of an adaptive mechanism to protect the heart in conditions that exacerbate diabetes.

Abstract
This study aimed to explore novel long non-coding RNAs (lncRNAs) and the underlying mechanisms involved in childhood acute lymphoblastic leukemia (cALL). The GSE67684 dataset was downloaded from the Gene Expression Omnibus. Differentially expressed genes (DEGs) and lncRNAs (DELs) between Days 0, 8, 15 and 33 were isolated using random variance model corrective analysis of variance. Overlapping DEGs and DELs were clustered using Cluster 3.0. Bio-functional enrichment analysis was performed using Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG). Interactions between lncRNAs and mRNAs were calculated using dynamic simulations, and interactions among mRNAs were predicted using the STRING database. lncRNA-mRNA and protein-protein interaction (PPI) networks were visualized using Cytoscape. Subsequently, the expression levels of lncRNAs in biological samples from children with or without cALL were validated using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). A total of 593 overlapping DEGs and 21 DELs were identified. After clustering, Profile 26 exhibited a continuously increasing temporal trend, whereas Profile 1 exhibited a continuous decreasing trend. Upregulated DEGs were significantly enriched in 1,825 GO terms and 166 KEGG pathways, whereas downregulated DEGs were significantly enriched in 196 GO terms and 90 KEGG pathways. The lncRNAs NONHSAT027612.2 and NONHSAT134556.2 were the top two regulators in the lncRNA-mRNA network. Toll-like receptor 4, cathepsin G, nucleotide-binding oligomerization domain containing 2 and cathepsin S may be considered the hub genes of the PPI network. RT-qPCR results indicated that the expression levels of the lncRNAs NONHSAT027612.2 and NONHSAT134556.2 were significantly elevated in the blood and bone marrow of patients with cALL compared with the controls. In conclusion, the lncRNAs NONHSAT027612.2 and NONHSAT134556.2 may serve important roles in the pathogenesis of cALL via regulating immune response-associated pathways.

Abstract
Long noncoding RNAs (lncRNAs) are RNAs longer than 200 nt in length that are characterized by low levels of sequence conservation and expression; lncRNAs modulate various biological functions at epigenetic, transcriptional and post-transcriptional levels, or directly regulate protein activity. As a family of small and evolutionarily conserved noncoding RNAs, microRNAs (miRNAs) are capable of regulating physiological and pathological processes via inhibiting target mRNA translation or promoting mRNA degradation. A number of studies have confirmed that both lncRNAs and miRNAs are closely associated with the development of cardiovascular diseases (CVDs), such as cardiac remodelling, heart failure, myocardial injury and arrhythmia, and that they act as biomarkers, potential therapeutic targets or strong indicators of prognosis; however, the underlying molecular mechanism has not been elucidated. Recently, emerging evidence showed that the novel regulatory mechanism underlying the crosstalk among lncRNAs, miRNAs and mRNAs plays a pivotal role in the pathophysiological processes of CVDs in response to stress stimuli. In this review, I comprehensively summarized the regulatory relationship of lncRNAs, miRNAs and mRNAs and highlighted the important role of the lncRNA-miRNA-mRNA axis in CVDs.

Abstract
Long noncoding RNAs (lncRNAs), a family of noncoding RNA transcripts with a length of <200 nucleotides (nts), have been associated with the pathological development of various types of carcinogenesis. Focally amplified lncRNA on chromosome 1 (FAL1) is a recently identified lncRNA. In the current study, we aimed to investigate the physiological function of FAL1 in esophageal squamous cell carcinoma (ESCC). Our findings demonstrate that FAL1 was associated with esophageal cancer cell survival by regulating mitochondrial fission. First, we found that the expression of the mitochondrial fission protein dynamin-related protein 1 (DRP1) was significantly reduced, but the expression of the mitochondrial fusion protein mitofusin 1 (Mfn1) was increased in ESCC tissues and esophageal cancer cell lines as compared with adjacent normal tissues and a normal esophagus epithelial cell line. In addition, we found that reduced expression of DRP1 in the esophageal cancer cell lines KYSE450 and EC9706 cells was associated with increased expression of FAL1. Inhibition of FAL1 promoted mitochondrial fission and mitochondrial dysfunction in KYSE450 and EC9706 cells mediated by DRP1. Silencing of DRP1 abolished FAL1-induced apoptosis through a mitochondrial-dependent pathway. Our findings suggest that FAL1/DRP1 could be a therapeutic target for the treatment of ESCC. © 2018 IUBMB Life, 71(1):254-260, 2019.

Abstract
The meat quality of local breed pigs is more tender and juicier than the imported varieties. The important reason is that the intramuscular fat content is high. Even through modest sequence conservation and evolution, the expression pattern and function of long noncoding RNAs (lncRNAs) seem to be conserved. In spite of that, analysis of lncRNAs associated with intramuscular fat development remains unknown to us in porcine. Here, we systematically investigated lncRNAs of intramuscular adipocytes of fat local Bamei pigs and lean Large White pigs to consider the function of lncRNAs on intramuscular fat development. We selected three piglets of both breeds separately to isolate intramuscular preadipocytes, performed RNA sequencing across four stages (0, 2, 4, and 8 d) during the intramuscular preadipocytes differentiation, and identified 1932 lncRNAs (760 novel). In addition, we have screened lnc_000414 closely related to fat synthesis. This lncRNA function as an inhibitor in the proliferation of porcine intramuscular adipocytes. These novel findings will provide new targets for improving pork quality and making pig breeding better.

Abstract
Non-coding RNAs (ncRNAs) are considered major players in physiological and pathological processes based on their versatile regulatory roles in different diseases including cardiovascular disease. Circular RNAs (circRNAs), a newly discovered class of RNAs, constitute a substantial fraction of the mammalian transcriptome and are abundantly expressed in the cardiovascular system. However, the regulatory functions of these circRNAs in ischemic cardiac disease remain largely unknown. Here, we investigated the role of a circRNA transcribed from the sodium/calcium exchanger 1 (ncx1) gene, named circNCX1, in oxidative stress-induced cardiomyocyte apoptosis during ischemic myocardial injury. Methods: Divergent polymerase chain reaction (PCR) was conducted to amplify the circRNA. The circular structure of circNCX1 was verified by Sanger sequencing and RNase R digestion. The subcellular localization of circNCX1 was detected by fluorescence in situ hybridization (FISH). To test the expression pattern and function of circNCX1 during oxidative stress, H9c2 cells and neonatal rat cardiomyocytes were treated with H2O2 or hypoxia-reoxygenation (H/R). Mechanistically, the interaction of circNCX1 with miRNA was examined by AGO2-IP and RNA pull-down assays. The regulatory role of circNCX1 in target gene expression was tested by western blot and luciferase reporter assays. At the animal level, we constructed a myocardial ischemia-reperfusion (I/R) mouse model to analyze the effect of circNCX1 on heart function, cardiomyocyte apoptosis and cardiac remodeling. Results: circNCX1 was increased in response to reactive oxygen species (ROS) and promotes cardiomyocyte apoptosis by acting as an endogenous miR-133a-3p sponge. Due to competitive binding of circNCX1 to miR-133a-3p, the suppressive activity of pro-apoptotic gene cell death-inducing protein (CDIP1) by miR-133a-3p was reduced. Knockdown of circNCX1 in murine cardiomyocytes and heart tissues reduced the levels of CDIP1 and attenuated the apoptosis and I/R injury. Conclusions: Our findings reveal a novel regulatory pathway that comprises circNCX1, miR-133a-3p and CDIP1, that is involved in cardiomyocyte apoptosis. This pathway may serve as a potential therapeutic avenue for ischemic heart diseases.

Abstract
Cancer is the leading cause of morbidity and mortality in the United States and globally. Owing to improved early diagnosis and advances in oncological therapeutic options, the number of cancer survivors has steadily increased. Such efficient cancer therapies have also lead to alarming increase in cardiovascular complications in a significant proportion of cancer survivors, due to adverse cardiovascular effects such as cardiotoxicity, cardiac atrophy, and myocarditis. This has emerged as a notable concern in healthcare and given rise to the new field of cardioncology, which aims at understanding the processes that occur in the two distinct disorders and how they interact to influence the progression of each other. A key player in both cancer and heart failure is the genome, which is predominantly transcribed to noncoding RNAs (ncRNAs). Since the emergence of ncRNAs as master regulators of gene expression, several reports have shown the relevance of ncRNAs in cancer and cardiovascular disorders. However, the knowledge is quite limited regarding the relevance of ncRNAs in cardioncology. The objective of this review is to summarize the current knowledge of ncRNAs in the context of cardioncology. Furthermore, the therapeutic strategies as well as the prospective translational applications of these ncRNA molecules to the clinics are also discussed.

Abstract
Current management of liver ischemia-reperfusion (I/R) injury is mainly based on supportive care and no specific treatment is available. Irisin, a recently identified hormone, plays pivotal roles in energy expenditure and oxidative metabolism; however, it remains unknown whether irisin has any protective effects on hepatic I/R injury. In this study, we found that serum and liver irisin levels were markedly decreased at 24 h after hepatic I/R. Treatment with exogenous irisin improved liver function, reduced liver necrosis and cell apoptosis, and relieved inflammatory response after hepatic I/R. Meanwhile, exogenous irisin markedly inhibited mitochondrial fission related protein dynamin related protein 1 (drp-1) and fission 1 (Fis-1) expression in hepatic I/R. Additionally, treatment with exogenous irisin increased mitochondrial content and increased mitochondrial biogenesis related peroxisome proliferative activated receptor-γ (PPARγ) co-activator 1α (PGC-1α) and mitochondrial transcription factor (TFAM) expression. Furthermore, irisin decreased oxidative stress by upregulating uncoupling proteins (UCP) 2 expression in hepatic I/R. The results reveal that treatment with exogenous irisin alleviated hepatic I/R injury by restraining mitochondrial fission, promoting mitochondrial biogenesis and relieving oxidative stress. Irisin treatment appears to be a novel and promising therapeutic approach for hepatic I/R injury. Irisin protects hepatocytes against ischemia/reperfusion (I/R)-induced injury. Irisin inhibits excessive mitochondrial fission after hepatic I/R. Irisin promotes mitochondrial biogenesis after hepatic I/R. Irisin reduces oxidative stress after hepatic I/R.

Abstract
In addition to serving as a prosthetic group for enzymes and a hemoglobin structural component, heme is a crucial homeostatic regulator of erythroid cell development and function. While lncRNAs modulate diverse physiological and pathological cellular processes, their involvement in heme-dependent mechanisms is largely unexplored. In this study, we elucidated a lncRNA (UCA1)-mediated mechanism that regulates heme metabolism in human erythroid cells. We discovered that UCA1 expression is dynamically regulated during human erythroid maturation, with a maximal expression in proerythroblasts. UCA1 depletion predominantly impairs heme biosynthesis and arrests erythroid differentiation at the proerythroblast stage. Mechanistic analysis revealed that UCA1 physically interacts with the RNA-binding protein PTBP1, and UCA1 functions as an RNA scaffold to recruit PTBP1 to ALAS2 mRNA, which stabilizes ALAS2 mRNA. These results define a lncRNA-mediated posttranscriptional mechanism that provides a new dimension into how the fundamental heme biosynthetic process is regulated as a determinant of erythrocyte development. LncRNAs modulate diverse physiological cellular processes, however, their involvement in heme-dependent processes are not yet clear. Here the authors reveal the role of lncRNA UCA1 in erythroid cell development.

Abstract
Long noncoding RNAs (lncRNAs) are endogenous RNA transcripts longer than 200 nucleotides which regulate epigenetically the expression of genes but do not have protein-coding potential. They are emerging as potential key regulators of diabetes mellitus and a variety of cardiovascular diseases. Diabetic cardiomyopathy (DCM) refers to diabetes mellitus-elicited structural and functional abnormalities of the myocardium, beyond that caused by ischemia or hypertension. The purpose of this review was to summarize current status of lncRNA research for DCM and discuss the challenges and possible strategies of lncRNA research for DCM. A systemic search was performed using PubMed and Google Scholar databases. Major conference proceedings of diabetes mellitus and cardiovascular disease occurring between January, 2014 to August, 2018 were also searched to identify unpublished studies that may be potentially eligible. The pathogenesis of DCM involves elevated oxidative stress, myocardial inflammation, apoptosis, and autophagy due to metabolic disturbances. Thousands of lncRNAs are aberrantly regulated in DCM. Manipulating the expression of specific lncRNAs, such as H19, metastasis-associated lung adenocarcinoma transcript 1, and myocardial infarction-associated transcript, with genetic approaches regulates potently oxidative stress, myocardial inflammation, apoptosis, and autophagy and ameliorates DCM in experimental animals. The detail data regarding the regulation and function of individual lncRNAs in DCM are limited. However, lncRNAs have been considered as potential diagnostic and therapeutic targets for DCM. Overexpression of protective lncRNAs and knockdown of detrimental lncRNAs in the heart are crucial for defining the role and function of lncRNAs of interest in DCM, however, they are technically challenging due to the length, short life, and location of lncRNAs. Gene delivery vectors can provide exogenous sources of cardioprotective lncRNAs to ameliorate DCM, and CRISPR–Cas9 genome editing technology may be used to knockdown specific lncRNAs in DCM. In summary, current data indicate that LncRNAs are a vital regulator of DCM and act as the promising diagnostic and therapeutic targets for DCM.

J Cell Mol Med 2018; 22:5062-5075. [PMID: 30079603 PMCID: PMC6156284 DOI: 10.1111/jcmm.13790] [Citation(s) in RCA: 84] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2018] [Accepted: 06/16/2018] [Indexed: 12/19/2022] Open
Abstract
This study was designed to investigate whether ANRIL affected the aetiology of coronary artery disease (CAD) by acting on downstream miR-181b and NF-κB signalling. Altogether 327 CAD patients diagnosed by angiography were included, and mice models of CAD were established. Human coronary endothelial cells (HCAECs) and human umbilical vein endothelial cells (HUVECs) were also purchased. In addition, shRNA-ANRIL, shRNA-NC, pcDNA3.1-ANRIL, miR-181b mimic, miR-181b inhibitor and miR-NC were transfected into the cells. The lipopolysaccharides (LPS) and pyrrolidine dithiocarbamate (PDTC) were also added to activate or deactivate NF-κB signalling. Both highly expressed ANRIL and lowly expressed miR-181b were associated with CAD population aged over 60 years old, with smoking history, with hypertension and hyperlipidemia, with CHOL H 4.34 mmol/L, TG ≥ 1.93 mmol/L and Hcy ≥ 16.8 μmol/L (all P < 0.05). Besides, IL-6, IL-8, NF-κB, TNF-α, iNOS, ICAM-1, VCAM-1 and COX-2 expressions observed within AD mice models were all beyond those within NC and sham-operated groups (P < 0.05). Also VEGF and HSP 70 were highly expressed within AD mice models than within NC and sham-operated mice (P < 0.05). Transfection of either pcDNA-ANRIL or miR-181b inhibitor could significantly fortify HCAECs' viability and put on their survival rate. At the meantime, the inflammatory factors and vascular-protective parameters were released to a greater level (P < 0.05). Finally, highly expressed ANRIL also notably bring down miR-181b expression and raise p50/p65 expressions within HCAECs (P < 0.05). The joint role of ANRIL, miR-181b and NF-κB signalling could aid in further treating and diagnosing CAD.

Abstract
Since lncRNAs could modulate neoplastic development by modulating downstream miRNAs and genes, this study was carried out to figure out the synthetic contribution of HOTAIR, miR-613 and c-met to viability, apoptosis and proliferation of retinoblastoma cells. Totally 276 retinoblastoma tissues and tumour-adjacent tissues were collected, and human retinoblastoma cell lines (ie, Y79, HXO-Rb44, SO-Rb50 and WERI-RB1) were also gathered. Moreover, transfections of pcDNA3.1-HOTAIR, si-HOTAIR, miR-613 mimic, miR-613 inhibitor, pcDNA3.1/c-met were performed to evaluate the influence of HOTAIR, miR-613 and c-met on viability, apoptosis and epithelial-mesenchymal transition (EMT) of retinoblastoma cells. Dual-luciferase reporter gene assay was also arranged to confirm the targeted relationship between HOTAIR and miR-613, as well as between miR-613 and c-met. Consequently, up-regulated HOTAIR and down-regulated miR-613 expressions displayed associations with poor survival status of retinoblastoma patients (P < 0.05). Besides, inhibited HOTAIR and promoted miR-613 elevated E-cadherin expression, yet decreased Snail and Vimentin expressions (P < 0.05). Simultaneously, cell proliferation and cell viability were also less-motivated (P < 0.05). Nonetheless, c-met prohibited the functioning of miR-613, resulting in promoted cell proliferation and viability, along with inhibited cell apoptosis (P < 0.05). Finally, HOTAIR was verified to directly target miR-613, and c-met was the direct target gene of miR-613 (P < 0.05). In conclusion, the role of lncRNA HOTAIR/miR-613/c-met signalling axis in modulating retinoblastoma cells' viability, apoptosis and expressions of EMT-specific proteins might provide evidences for developing appropriate diagnostic and treatment strategies for retinoblastoma.

Abstract
SIGNIFICANCE The concepts of junk DNA and transcriptional noise are long gone as the existence of noncoding RNAs (ncRNAs) has been tested extensively in recent years. Given that the epigenetic status of cells affects many biological processes, how ncRNAs mechanistically contribute to these processes is of great interest. Recent Advances: Recent studies show that various ncRNAs interact with epigenetic and/or transcription factors to modulate the epigenetic status of cells directly and/or indirectly. There exists growing interest in the field of cardiovascular research to understand the roles of ncRNAs. Due to the large number of ncRNAs in the mammalian genome, only a handful of ncRNAs have been functionally elucidated, which makes it difficult to understand how ncRNAs interact with protein-coding genes and their encoded proteins. CRITICAL ISSUES Although the canonical function of microRNAs (miRNAs) to inhibit the translation of protein-coding genes is well established, the number of functionally annotated long noncoding RNAs (lncRNAs) is still small, which is especially true in the heart. FUTURE DIRECTIONS Future studies must connect the epigenetic controls of various cellular phenomena by incorporating both miRNAs and lncRNAs. Antioxid. Redox Signal. 29, 832-845.

Abstract
The current study aimed to investigate the role of long non-coding RNA (lncRNA) homeobox transcript antisense RNA (HOTAIR) in the pathogenesis of diabetic cardiomyopathy. Patients with diabetic cardiomyopathy, patients with diabetes but without cardiomyopathy and healthy controls were included in the current study. All participants underwent myocardial biopsy to collect myocardial tissues. Blood samples were also collected from each participant to prepare serum. Expression of HOTAIR in myocardial tissues was detected by reverse transcription-quantitative polymerase chain reaction. Receiver operating characteristic curve analysis was performed to evaluate the diagnostic value of serum HOTAIR for diabetic cardiomyopathy. AC16 human cardiomyocyte cells were treated with high glucose to observe the changes in expression of HOTAIR and phosphorylation of Akt. HOTAIR expression vector was transfected into cells of AC16 cell line and the effects of HOTAIR overexpression on cell viability and Akt phosphorylation were detected by MTT assay and western blot analysis, respectively. HOTAIR expression was significantly downregulated in myocardial tissues and serum of patients with diabetic cardiomyopathy compared with patients with diabetes and healthy controls. Serum HOTAIR could be used to effectively distinguish patients with diabetic cardiomyopathy from healthy controls. High glucose treatment inhibited HOTAIR expression and Akt phosphorylation. HOTAIR overexpression promoted Akt phosphorylation. HOTAIR overexpression improved AC16 cell viability, while PI3K/Akt inhibitor treatment reduced this effect. LncRNA HOTAIR may improve diabetic cardiomyopathy by increasing the viability of cardiomyocytes through activation of the PI3K/Akt pathway.

Abstract
Following completion of the human genome, it became evident that the majority of our DNA is transcribed into non-coding RNAs (ncRNAs) instead of protein-coding messenger RNA. Deciphering the function of these ncRNAs, including both small- and long ncRNAs (lncRNAs), is an emerging field of research. LncRNAs have been associated with many disorders and a number have been identified as key regulators in the development and progression of disease, including cardiovascular disease (CVD). CVD causes millions of deaths worldwide, annually. Risk factors include coronary artery disease, high blood pressure and ageing. In this review, we will focus on the roles of lncRNAs in the cellular and molecular processes that underlie the development of CVD: cardiomyocyte hypertrophy, fibrosis, inflammation, vascular disease and ageing. Finally, we discuss the biomarker and therapeutic potential of lncRNAs.

Abstract
OBJECTIVE To investigate the role of GAS5 on cardiomyocyte apoptosis. METHODS Myocardial infarction (MI) model was established by the left-anterior descending coronary artery ligation. Norepinephrine (NE) was used to induce cardiomyocyte apoptosis. GAS5 levels and mRNA expressions of Semaphorin 3a (sema3a) were measured by qRT-PCR. Protein level of sema3a was detected by Western blotting. Cardiomyocyte apoptosis was detected by flow cytometry assay. RNA pull-down and RIP assay were used to verify the combination between GAS5 and sema3a. Infarct size was measured by TTC staining. RESULTS GAS5 expression was increased in infarct boundary zone of MI group, while sema3a protein expression was decreased. Moreover, GAS5 expression in cardiomyocyte induced by NE was higher than control group, while sema3a protein expression was lower than control group. In addition, GAS5 could negatively regulate sema3a protein expression. pcDNA-GAS5 reversed cardiomyocyte apoptosis induced by NE, while pcDNA-sema3a countered the inhibitory effect. In animal experiment, overexpression of GAS5 decreased sema3a protein expression and reduced infarct size. CONCLUSION GAS5 could ameliorate cardiomyocyte apoptosis induced by MI via down-regulating sema3a.

Abstract
LncRNAs plays an important role in the regulation of gene expression. Identification of cancer-related lncRNAs GO terms and KEGG pathways is great helpful for revealing cancer-related functional biological processes. Therefore, in this study, we proposed a computational method to identify novel cancer-related lncRNAs GO terms and KEGG pathways. By using existing lncRNA database and Max-relevance Min-redundancy (mRMR) method, GO terms and KEGG pathways were evaluated based on their importance on distinguishing cancer-related and non-cancer-related lncRNAs. Finally, GO terms and KEGG pathways with high importance were presented and analyzed. Our literature reviewing showed that the top 10 ranked GO terms and pathways were really related to interpretable tumorigenesis according to recent publications.

Abstract
Noncoding RNAs are emerging as potent and multifunctional regulators in all biological processes. In parallel, a rapidly growing number of studies has unravelled associations between aberrant noncoding RNA expression and human diseases. These associations have been extensively reviewed, often with the focus on a particular microRNA (miRNA) (family) or a selected disease/pathology. In this Mini‐Review, we highlight a selection of studies in order to demonstrate the wide‐scale involvement of miRNAs and long noncoding RNAs in the pathophysiology of three types of diseases: cancer, cardiovascular and neurological disorders. This research is opening new avenues to novel therapeutic approaches.

Abstract
BACKGROUND Astragalus membranaceus has been clinically used in cerebral ischemia treatment in China and its main component, Astragaloside IV (Ast IV) shows anti-hypoxia activity, but the underlying mechanism has not been clearly clarified. This study was aimed to investigate the effects of Ast IV on hypoxia-induced injury in PC-12 cells as well as the underlying mechanism. METHODS Relative miR-124 expression was detected by qRT-PCR. Hic-5 expression was analyzed by qRT-PCR and Western blot. To alter miR-124 and Hic-5 expressions, cells were respectively transfected with miR-124 mimic and pEX-Hic-5. Cell proliferation and apoptosis were measured by BrdU assay and Annexin V-fluorescein isothiocynate (FITC)/propidium iodide (PI) double staining method, respectively. Besides, apoptotic proteins and cell proliferation-associated factors were analyzed by Western blot. RESULTS Ast IV alleviated hypoxia-induced injury in PC-12 cells by decreasing apoptosis (P < 0.01). Ast IV inhibited up-regulation of miR-124 induced by hypoxia (P < 0.01). miR-124 mimic impaired the anti-apoptotic effect of Ast IV on PC-12 cells (P < 0.01). Hic-5 expression was significantly down-regulated in miR-124 overexpressed cells (P < 0.001) and Hic-5 overexpression activated Sp1/Survivin signaling pathway (P < 0.001). CONCLUSION Ast IV could ameliorate hypoxia-induced injury in PC-12 cells by decreasing miR-124 expression and then up-regulating Hic-5 expression.

A Hearty Dose of Noncoding RNAs: The Imprinted DLK1-DIO3 Locus in Cardiac Development and Disease. J Cardiovasc Dev Dis 2018; 5:jcdd5030037. [PMID: 29996488 PMCID: PMC6162432 DOI: 10.3390/jcdd5030037] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 06/29/2018] [Accepted: 07/04/2018] [Indexed: 12/17/2022] Open
Abstract
The imprinted Dlk1-Dio3 genomic region harbors a noncoding RNA cluster encoding over fifty microRNAs (miRNAs), three long noncoding RNAs (lncRNAs), and a small nucleolar RNA (snoRNA) gene array. These distinct noncoding RNAs (ncRNAs) are thought to arise from a single polycistronic transcript that is subsequently processed into individual ncRNAs, each with important roles in diverse cellular contexts. Considering these ncRNAs are derived from a polycistron, it is possible that some coordinately regulate discrete biological processes in the heart. Here, we provide a comprehensive summary of Dlk1-Dio3 miRNAs and lncRNAs, as they are currently understood in the cellular and organ-level context of the cardiovascular system. Highlighted are expression profiles, mechanistic contributions, and functional roles of these ncRNAs in heart development and disease. Notably, a number of these ncRNAs are implicated in processes often perturbed in heart disease, including proliferation, differentiation, cell death, and fibrosis. However, most literature falls short of characterizing precise mechanisms for many of these ncRNAs, warranting further investigation. Taken together, the Dlk1-Dio3 locus represents a largely unexplored noncoding regulator of cardiac homeostasis, harboring numerous ncRNAs that may serve as therapeutic targets for cardiovascular disease.

Abstract
After being long considered as “junk” in the human genome, non-coding RNAs (ncRNAs) currently represent one of the newest frontiers in cardiovascular disease (CVD) since they have emerged in recent years as potential therapeutic targets. Different types of ncRNAs exist, including small ncRNAs that have fewer than 200 nucleotides, which are mostly known as microRNAs (miRNAs), and long ncRNAs that have more than 200 nucleotides. Recent discoveries on the role of ncRNAs in epigenetic and transcriptional regulation, atherosclerosis, myocardial ischemia/reperfusion (I/R) injury and infarction (MI), adverse cardiac remodeling and hypertrophy, insulin resistance, and diabetic cardiomyopathy prompted vast interest in exploring candidate ncRNAs for utilization as potential therapeutic targets and/or diagnostic/prognostic biomarkers in CVDs. This review will discuss our current knowledge concerning the roles of different types of ncRNAs in cardiovascular health and disease and provide some insight on the cardioprotective signaling pathways elicited by the non-coding genome. We will highlight important basic and clinical breakthroughs that support employing ncRNAs for treatment or early diagnosis of a variety of CVDs, and also depict the most relevant limitations that challenge this novel therapeutic approach.

Abstract
Esophageal squamous cell carcinoma (ESCC) is the eighth cause of cancer-related deaths worldwide. To screen potential biomarkers associated with early recurrence/metastasis (R/M) of ESCC patients after radical resection, ESCC patients were analyzed by a comparative proteomics analysis using iTRAQ with RPLC-MS to screen differential proteins among R/M groups and adjacent normal tissues. The proteins were identified by qRT-PCR, Western blotting, and tissue microarray. The protein and mRNA expression difference of PHB2 between tumor tissues of ESCC patients and adjacent normal tissues, ESCC patients with and without metastasis, four ESCC cell lines and normal esophageal epithelial cells were inspected using immunohistochemical staining, qRT-PCR, and Western blotting. The EC109 and TE1 cells were used to establish PHB2 knockdown cell models, and their cell proliferation and invasion ability were determined by cell counting method, Transwell® assay. Thirteen proteins were selected by cutoff value of 0.67 fold for underexpression and 1.5-fold for overexpression. Seven proteins were confirmed to be associated with R/M among the 13 proteins. The potential biomarker PHB2 for early recurrence/metastasis of ESCC was identified. PHB2 expression was related to the OS of ESCC patients (P = 0.032) and had high levels in the tumor tissues and human cell lines of ESCC (P = 0.0002). Also, the high PHB2 expression promoted the metastasis of ESCC (P = 0.0075), suggesting high PHB2 expression was a potential prognostic biomarker. Experiments showed that PHB2 could significantly promote the proliferation and cell invasion ability of human ESCC cell lines and the knockdown of PHB2 suppressed the phosphorylation level of AKT, as well as the expression of MMP9 and RAC1. PHB2 could predict the early metastasis of ESCC patients.

Abstract
PURPOSE OF REVIEW Noncoding RNAs have emerged as important regulators of cellular and systemic lipid metabolism. In particular, the enigmatic class of long noncoding RNAs have been shown to play multifaceted roles in controlling transcriptional and posttranscriptional gene regulation. In this review, we discuss recent advances, current challenges and future opportunities in understanding the roles of lncRNAs in the regulation of lipid metabolism during health and disease. RECENT FINDINGS Despite comprising the majority of the transcriptionally active regions of the human genome, lncRNA functions remain poorly understood, with fewer than 1% of human lncRNAs functionally characterized. Broadly defined as nonprotein coding transcripts greater than 200 nucleotides in length, lncRNAs execute their functions by forming RNA-DNA, RNA-protein, and RNA-RNA interactions that regulate gene expression through diverse mechanisms, including epigenetic remodeling of chromatin, transcriptional activation or repression, posttranscriptional regulation of mRNA, and modulation of protein activity. It is now recognized that in lipid metabolism, just as in other areas of biology, lncRNAs operate to regulate the expression of individual genes and gene networks at multiple different levels. SUMMARY The complexity revealed by recent studies showing how lncRNAs can alter systemic and cell-type-specific cholesterol and triglyceride metabolism make it clear that we have entered a new frontier for discovery that is both daunting and exciting.

Significance of prohibitin domain family in tumorigenesis and its implication in cancer diagnosis and treatment. Cell Death Dis 2018; 9:580.

Abstract
Prohibitin (PHB) was originally isolated and characterized as an anti-proliferative gene in rat liver. The evolutionarily conserved PHB gene encodes two human protein isoforms with molecular weights of ~33 kDa, PHB1 and PHB2. PHB1 and PHB2 belong to the prohibitin domain family, and both are widely distributed in different cellular compartments such as the mitochondria, nucleus, and cell membrane. Most studies have confirmed differential expression of PHB1 and PHB2 in cancers compared to corresponding normal tissues. Furthermore, studies verified that PHB1 and PHB2 are involved in the biological processes of tumorigenesis, including cancer cell proliferation, apoptosis, and metastasis. Two small molecule inhibitors, Rocaglamide (RocA) and fluorizoline, derived from medicinal plants, were demonstrated to interact directly with PHB1 and thus inhibit the interaction of PHB with Raf-1, impeding Raf-1/ERK signaling cascades and significantly suppressing cancer cell metastasis. In addition, a short peptide ERAP and a natural product xanthohumol were shown to target PHB2 directly and prohibit cancer progression in estrogen-dependent cancers. As more efficient biomarkers and targets are urgently needed for cancer diagnosis and treatment, here we summarize the functional role of prohibitin domain family proteins, focusing on PHB1 and PHB2 in tumorigenesis and cancer development, with the expectation that targeting the prohibitin domain family will offer more clues for cancer therapy.

Abstract
Protein coding sequences account for around 3% of the human genome, the rest are noncoding RNA (ncRNA) including long ncRNA (lncRNA) and miRNA. Accumulating evidence indicates that lncRNAs and miRNAs are candidate biomarkers for diagnosis, prognosis and therapy of cardiovascular diseases. The lncRNAs act as sponge-like effects on numerous miRNAs, subsequently regulating miRNAs and their targets, mRNA functions. The role of lncRNA–miRNA–mRNA axis in pathogenesis of cardiovascular diseases has been recently reported and highlighted. Herein, this review discusses emerging roles of lncRNA–miRNA–mRNA axis in cardiovascular pathophysiology and regulation, with a novel focus on cardioprotective network activities of the two subgroup ncRNAs.

Abstract
The aberrant expression of long noncoding RNAs (lncRNAs) has been involved in various human tumors including hepatocellular carcinoma (HCC). Our study aimed to investigate the potential molecular mechanism of lncRNA myocardial infarction-associated transcript (MIAT) in HCC. The expression of MIAT and micro-RNA (miR)-214 in HCC tissues and cells was examined by quantitative real-time PCR, and the levels of enhancer of zeste homolog 2 (EZH2) and β-catenin were detected by Western blot assay. Immunoprecipitation analysis was used to detect the level of H3/H4 histone acetylation. RNA pull-down assay was performed to confirm the targeting regulatory relationship between miR-214 and MIAT. Cell viability, proliferation, and invasion were analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), [3H]thymidine incorporation, and Transwell assays, respectively. BALB/c nude mice were used to establish a hepatocellular carcinoma animal model with subcutaneous injection of SK-HEP-1 cells. Upregulation of MIAT is related to the proliferation and invasion of HCC, and downregulating MIAT expression inhibited HCC cell proliferation and invasion. The H3/H4 histone acetylation level of MIAT promoter in HCC tissues was higher than that in normal tissues. MIAT negatively regulated miR-214 in HCC cells. Inhibition of miR-214 reversed the influence of MIAT downregulation on HCC cell proliferation and invasion. In nude mouse xenograft models, downregulation of MIAT markedly suppressed the tumor growth of HCC via releasing miR-214. In conclusion, lncRNA MIAT promotes the proliferation and invasion of HCC cells through sponging miR-214, which brings a novel target for the therapy and prognosis of hepatocellular carcinoma. NEW & NOTEWORTHY This is the first research showing long noncoding RNA (lncRNA) myocardial infarction-associated transcript (MIAT) to have a regulatory effect on hepatocellular carcinoma. Micro-RNA (miR)-214 could be sponged by MIAT to promote the proliferation and invasion of hepatocellular carcinoma cells. The lncRNA MIAT/miR-214 axis brings a novel insight for the therapy and prognosis of hepatocellular carcinoma.

Abstract
Little is known about the role of long non-coding RNA XIST in the development of colon cancer. The aim of the present study was to investigate the levels of XIST in colon cancer, and explore its underlying mechanism. In this study, we found XIST expression level was upregulated in colon cancer tissues and cell lines. In addition, the growth rate of cells transfected with si-XIST was significantly decreased compared to that with si-NC, which was reversed by miR-34a targeted with 3'-UTR. Moreover, miR-34a suppressed the expression of WNT1 by binding with the 3'-UTR, which interact with WNT1 to inhibit the proliferation of cells. Furthermore, miR-34a inhibitor rescued the dysregulation of WNT1, β-catenin, cyclinD1, c-Myc and MMP-7 by si-XIST. Besides, XIST knockdown inhibited tumor growth in vivo. In short, the current study suggests XIST plays as an important role in colon cancer progression targeted by miR-34a via Wnt/β-catenin signaling pathway, providing a novel insight for the pathogenesis and underlying therapeutic target for colon cancer.

Abstract
BACKGROUND Long noncoding RNAs (LncRNAs) represent a class of widespread and diverse endogenous RNAs that can posttranscriptionally regulate gene expression through the interaction with RNA-binding proteins and micro RNAs (miRNAs). Here, we report that in breast carcinoma cells, the insulin-like growth factor 2 messenger RNA binding protein (IMP1) binds to lncRNA urethral carcinoma-associated 1 (UCA1) and suppresses the UCA1-induced invasive phenotype. METHODS RT-qPCR and RNA sequence assays were used to investigate the expression of UCA1 and miRNAs in breast cancer cells in response to IMP1 expression. The role of IMP1-UCA1 interaction in cell invasion was demonstrated by transwell analysis through loss-of-function and gain-of-function effects. RNA pull-down and RNA binding protein immunoprecipitation (RIP) were performed to confirm the molecular interactions of IMP1-UCA1 and UCA1-miR-122-5p involved in breast cancer cells. RESULTS In breast cancer cells, IMP1 interacts with UCA1 via the "ACACCC" motifs within UCA1 and destabilizes UCA1 through the recruitment of CCR4-NOT1 deadenylase complex. Meanwhile, binding of IMP1 prevents the association of miR-122-5p with UCA1, thereby shifting the availability of miR-122-5p from UCA1 to the target mRNAs and reducing the UCA1-mediated cell invasion. Accordingly, either IMP1 silencing or UCA1 overexpression resulted in reduced levels of free miR-122-5p within the cytoplasm, affecting miR-122-5p in regulating its target mRNAs. CONCLUSIONS Our study provides initial evidence that interaction between IMP1 and UCA1 enhances UCA1 decay and competes for miR-122-5p binding, leading to the liberation of miR-122-5p activity and the reduction of cell invasiveness.

Abstract
Cisplatin-resistant ovarian cancer occurs in patients with ovarian cancer treated with cisplatin-based chemotherapy, which results in tumor progression during treatment, or recurrence of the tumor within 6 months of the treatment. It is vital that a novel biomarker for diagnosis, or an efficient therapeutic target of cisplatin-resistant ovarian is identified. Long non-coding (lnc)RNAs were determined to serve critical functions in a variety of distinct types of cancer, including ovarian cancer; however, there is limited knowledge regarding the differential expression levels of lncRNAs in cisplatin-resistant and cisplatin-sensitive ovarian cancer. Therefore, in the present study, the expression levels were determined for these cancer types. The lncRNA expression profile in cisplatin-resistant ovarian cancer was analyzed and compared with the results for cisplatin-sensitive ovarian cancer; gene ontology and pathway analysis demonstrated that the dysregulated lncRNAs participated in important biological processes. Subsequently, it was identified that these dysregulated lncRNAs were present in other ovarian cancer tissues and in SKOV3 ovarian cancer cells, as well as its cisplatin-resistant clone, SKOV3/CDDP. In addition, it was revealed that 8 lncRNAs (Enst0000435726, Enst00000585612, Enst00000566734, Enst00000453783, NR_023915, RP11_697E22.2, uc010jub.1 and tcons_00008505) were associated with cisplatin-resistant ovarian cancer. The present study may assist in improving understanding of the initiation and developmental mechanisms underlying cisplatin-resistant ovarian cancer, which could aid future studies in discovering potential biomarkers for diagnosis or therapeutic targets that may be used in clinical treatment.

Abstract
Long non-coding RNAs (lncRNAs) are critical regulators in a multitude of biological processes. Recent evidences demonstrate potential pathogenetic implications of lncRNAs in diabetic cardiomyopathy (DCM); however, the majority of lncRNAs have not been comprehensively characterized. While the precise molecular mechanisms underlying the functions of lncRNAs remain to be deciphered in DCM, emerging data in other pathophysiological conditions suggests that lncRNAs can have versatile features such as genomic imprinting, acting as guides for certain histone-modifying complexes, serving as scaffolds for specific molecules, or acting as molecular sponges. In an effort to better understand these features of lncRNAs in the context of DCM, our review will first summarize some of the key molecular alterations that occur during fibrosis in the diabetic heart (extracellular proteins and endothelial-to-mesenchymal transitioning), followed by a review of the current knowledge on the crosstalk between lncRNAs and major epigenetic mechanisms (histone methylation, histone acetylation, DNA methylation, and microRNAs) within this fibrotic process.

Abstract
Aim To explore the expression and clinical significance of long noncoding RNA (lncRNA) gastric cancer-associated transcript 3 (GACAT3) in human colorectal cancer (CRC). Methods Expression of GACAT3 in CRC tissues and cell lines was measured using quantitative real-time PCR. CCK-8 and colony formation assays were used to assess the effect of GACAT3 on CRC cell line proliferation. Transwell invasion and migration assays were performed to detect the effect of GACAT3 on CRC cell line invasion and migration. Bioinformatics prediction, luciferase reporter assay, and pull-down assay were used to determine if miR-149 was a target of GACAT3. In addition, we also conducted colony formation assays and invasion assays to verify that GACAT3 promotes tumor progression through miR-149. Finally, in vivo tumorigenesis studies were used to demonstrate subcutaneous tumor growth. Results In the present study, we found that GACAT3 was highly expressed in CRC tissues and cell lines. Si-GACAT3 significantly decreased cell proliferation, motility, and invasiveness both in vitro and in vivo. We confirmed that downregulated GACAT3 significantly increased the expression of miR-149, and miR-149 binds to GACAT3 in a sequence-specific manner using luciferase reporter assays and pull-down assay. Further functional experiments indicated that GACAT3 could directly upregulate SP1 and STAT3 expressions by functioning as a competing endogenous RNA for miR-149, and consequentially, promoting CRC cell proliferation and invasion in vitro. Conclusion This study demonstrated that GACAT3 promotes tumor progression through competitive binding to miR-149 and suggests a promising new strategy for anti-CRC therapy.

Abstract
Non-coding RNAs, once considered "genomic junk", are now known to play central roles in the dynamic control of transcriptional and post-transcriptional gene expression. Long non-coding RNAs (lncRNAs) are an expansive class of transcripts broadly described as greater than 200 nucleotides in length. While most lncRNAs are species-specific, their lack of conservation does not imbue a lack of function. LncRNAs have been found to regulate numerous diverse biological functions, including those central to macrophage differentiation and activation. Through their ability to form RNA-DNA, RNA-protein and RNA-RNA interactions, lncRNAs have been implicated in the regulation of myeloid lineage determination, and innate and adaptive immune functions, among others. In this review, we discuss recent advances, current challenges and future opportunities in understanding the roles of lncRNAs in macrophage functions in homeostasis and disease.

World J Gastroenterol 2018; 24:1004-1012. [PMID: 29531464 PMCID: PMC5840465 DOI: 10.3748/wjg.v24.i9.1004] [Citation(s) in RCA: 58] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2017] [Revised: 12/26/2017] [Accepted: 01/15/2018] [Indexed: 02/07/2023] Open
Abstract
AIM To investigate the role of long noncoding RNA (lncRNA) RP4 in colorectal cancer.
METHODS Lentivirus-mediated lncRNA RP4 overexpression and knockdown were performed in the colorectal cancer cell line SW480. Cell proliferation, tumor growth, and early apoptosis were evaluated by a cell counting kit-8 assay, an in vivo xenograft tumor model, and annexin V/propidium iodide staining, respectively. Analysis of the lncRNA RP4 mechanism involved assessment of the association of its expression with miR-7-5p and the SH3GLB1 gene. Western blot analysis was also performed to assess the effect of lncRNA RP4 on the autophagy-mediated cell death pathway and phosphatidylinositol-3-kinase (PI3K)/Akt signaling.
RESULTS Cell proliferation, tumor growth, and early apoptosis in SW480 cells were negatively regulated by lncRNA RP4. Functional experiments indicated that lncRNA RP4 directly upregulated SH3GLB1 expression by acting as a competing endogenous RNA (ceRNA) for miR-7-5p. This interaction led to activation of the autophagy-mediated cell death pathway and de-repression of PI3K and Akt phosphorylation in colorectal cancer cells in vivo.
CONCLUSION Our results demonstrated that lncRNA RP4 is a ceRNA that plays an important role in the pathogenesis of colorectal cancer, and could be a potential therapeutic target for colorectal cancer treatment.
