Abstract
BACKGROUND Gene regulation by microRNA (miRNA) is central in T lymphocytes differentiation processes. Here, we investigate miRNA-29b (miR-29b) roles in the reprogramming of T cell differentiation, which can be a promising therapeutic avenue for various types of inflammatory disorders such as rheumatoid arthritis and multiple sclerosis. METHODS AND RESULTS Adipose Mesenchymal Stem Cell-derived exosomes (AMSC-Exo) enriched with miR-29b were delivered into naive CD4+ T (nCD4+) cells. The expression level of important transcription factors including RAR-related orphan receptor gamma (RORγt), GATA3 binding protein (GATA3), T-box transcription factor 21, and Forkhead box P3 was determined by quantitative Real-Time PCR. Moreover, flow cytometry and Enzyme-linked Immunosorbent Assay were respectively used to measure the frequency of T regulatory cells and the levels of cytokines production (Interleukin 17, Interleukin 4, Interferon-gamma, and transforming growth factor beta. This study indicates that the transfection of miR-29b mimics into T lymphocytes through AMSC-Exo can alter the CD4+ T cells' differentiation into other types of T cells. CONCLUSIONS In conclusion, AMSC-Exo-based delivery of miR-29b can be considered as a new fascinating avenue for T cell differentiation inhibition and the future treatment of several inflammatory disorders.

Pathol Res Pract 2023; 243:154375. [PMID: 36801506 DOI: 10.1016/j.prp.2023.154375] [Citation(s) in RCA: 65] [Impact Index Per Article: 65.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Revised: 02/10/2023] [Accepted: 02/11/2023] [Indexed: 02/16/2023]
Abstract
MicroRNAs (miRNAs) are a class of short, non-coding RNAs that function post-transcriptionally to regulate gene expression by binding to particular mRNA targets and causing destruction of the mRNA or translational inhibition of the mRNA. The miRNAs control the range of liver activities, from the healthy to the unhealthy. Considering that miRNA dysregulation is linked to liver damage, fibrosis, and tumorigenesis, miRNAs are a promising therapeutic strategy for the evaluation and treatment of liver illnesses. Recent findings on the regulation and function of miRNAs in liver diseases are discussed, with an emphasis on miRNAs that are highly expressed or enriched in hepatocytes. Alcohol-related liver illness, acute liver toxicity, viral hepatitis, hepatocellular carcinoma, liver fibrosis, liver cirrhosis, and exosomes in chronic liver disease all emphasize the roles and target genes of these miRNAs. We briefly discuss the function of miRNAs in the etiology of liver diseases, namely in the transfer of information between hepatocytes and other cell types via extracellular vesicles. Here we offer some background on the use of miRNAs as biomarkers for the early prognosis, diagnosis, and assessment of liver diseases. The identification of biomarkers and therapeutic targets for liver disorders will be made possible by future research into miRNAs in the liver, which will also help us better understand the pathogeneses of liver diseases.

Whole-transcriptome sequencing revealed differentially expressed mRNAs and non-coding RNAs played crucial roles in NiONPs-induced liver fibrosis. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2022; 248:114308. [PMID: 36410144 DOI: 10.1016/j.ecoenv.2022.114308] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 11/14/2022] [Accepted: 11/15/2022] [Indexed: 06/16/2023]
Abstract
Nickel oxide nanoparticles (NiONPs) induced liver fibrosis, while its mechanisms associated with transcriptome remained unclear. This study aimed to investigate the roles of differentially expressed (DE) messenger RNAs (mRNAs) and non-coding RNAs (ncRNAs) in NiONPs-induced liver fibrosis, and further confirm whether JNK/c-Jun pathway enriched by the DE RNAs was involved in the regulation of the disease. A liver fibrosis rat model was established by intratracheal perfusion of NiONPs twice a week for 9 weeks. Whole-transcriptome sequencing was applied to obtain expression profiles of mRNAs, long non-coding RNAs (lncRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs) in the model rat and control liver tissues. Comparing the RNA expression profiles of the model and control liver tissues, we identified 324 DE mRNAs, 129 DE lncRNAs, 24 DE miRNAs and 33 DE circRNAs, and the potential interactions among them were revealed by constructing two co-expression networks, including lncRNA-miRNA-mRNA and circRNA-miRNA-mRNA networks. Using RT-qPCR, we verified the sequencing results of some RNAs in the networks and obtained similar expression profiles, indicating our sequencing results were reliable and referable. Through Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, we predicted the biological functions and signaling pathways potentially related to NiONPs-induced liver fibrosis, such as "positive regulation of JNK cascade", "inflammatory response", "transcription factor binding", and MAPK, Wnt, PI3K-Akt signaling pathways. JNK/c-Jun pathway, a subclass of MAPK signal, was selected for further investigation because it was significantly enriched by fibrosis-related DE genes and activated in animal models. In vitro, we detected the cytotoxicity of NiONPs on LX-2 cells and treated the cells with 5 μg/ml NiONPs for 12 h. The results showed NiONPs induced the up-regulated protein expression of fibrotic factors collagen-1a1 (Col-1a1) and matrix metalloproteinas2 (MMP2) and JNK/c-Jun pathway activation. While these effects were reversed after JNK/c-Jun pathway was blocked by SP600125 (JNK pathway inhibitor), indicating the pathway was involved in NiONPs-induced excessive collagen formation. In conclusion, our results revealed the DE mRNAs and ncRNAs played crucial roles in NiONPs-induced liver fibrosis, and JNK/c-Jun pathway mediated the development of the disease.

Abstract
Inflammation is a multifactorial process and various biological mechanisms and pathways participate in its development. The presence of inflammation is involved in pathogenesis of different diseases such as diabetes mellitus, cardiovascular diseases and even, cancer. Non-coding RNAs (ncRNAs) comprise large part of transcribed genome and their critical function in physiological and pathological conditions has been confirmed. The present review focuses on miRNAs, lncRNAs and circRNAs as ncRNAs and their potential functions in inflammation regulation and resolution. Pro-inflammatory and anti-inflammatory factors are regulated by miRNAs via binding to 3'-UTR or indirectly via affecting other pathways such as SIRT1 and NF-κB. LncRNAs display a similar function and they can also affect miRNAs via sponging in regulating levels of cytokines. CircRNAs mainly affect miRNAs and reduce their expression in regulating cytokine levels. Notably, exosomal ncRNAs have shown capacity in inflammation resolution. In addition to pre-clinical studies, clinical trials have examined role of ncRNAs in inflammation-mediated disease pathogenesis and cytokine regulation. The therapeutic targeting of ncRNAs using drugs and nucleic acids have been analyzed to reduce inflammation in disease therapy. Therefore, ncRNAs can serve as diagnostic, prognostic and therapeutic targets in inflammation-related diseases in pre-clinical and clinical backgrounds.

Abstract
Liver fibrosis is an outcome of chronic hepatic injury, which can eventually result in cirrhosis, liver failure, and even liver cancer. The activation of hepatic stellate cell (HSC) is a prominent driver of liver fibrosis. Recently, it has been found that the crosstalk between HSCs and immune cells, including hepatic macrophages, plays an important role in the initiation and development of liver fibrosis. As a vital vehicle of intercellular communication, exosomes transfer specific cargos into HSCs from macrophages. Here, we show that exosomes derived from lipopolysaccharide (LPS)-treated macrophages has higher expression level of miR-500. And overexpression or inhibition of miR-500 in macrophage exosomes could promote or suppress HSC proliferation and activation. Treatment of exosomes with miR-500 overexpression can accelerate liver fibrosis in CCl4-induced liver fibrosis mouse model. miR-500 promotes HSC activation and liver fibrosis via suppressing MFN2. Moreover, miR-500 in serum exosomes could be a biomarker for liver fibrosis. Taken together, exosomal miR-500 derived from LPS-activated macrophages promotes HSC proliferation and activation by targeting MFN2 in liver fibrosis.

Abstract
Peroxisome proliferator-activated receptors (PPARs) are ligand-modulated nuclear receptors that play pivotal roles in nutrient sensing, metabolism, and lipid-related processes. Correct control of their target genes requires tight regulation of the expression of different PPAR isoforms in each tissue, and the dysregulation of PPAR-dependent transcriptional programs is linked to disorders, such as metabolic and immune diseases or cancer. Several PPAR regulators and PPAR-regulated factors are epigenetic effectors, including non-coding RNAs, epigenetic enzymes, histone modifiers, and DNA methyltransferases. In this review, we examine advances in PPARα and PPARγ-related epigenetic regulation in metabolic disorders, including obesity and diabetes, immune disorders, such as sclerosis and lupus, and a variety of cancers, providing new insights into the possible therapeutic exploitation of PPAR epigenetic modulation.

Abstract
A conceptual framework for understanding abnormal endometrial decidualization, with considerable significance for the diagnosis and treatment of abnormal decidualization-related changes in non-receptive endometrium in implantation failure during early pregnancy is very important. Here, we found the expression levels of miR-29a in endometrial tissues were associated with the menstrual phases and pregnancy outcome. Inhibition of miR-29a led to decreased decidualization of endometrial stromal cells (ESCs) in vitro, whereas Tet methylcytosine dioxygenase 3 (TET3) and its potential demethylation target, the collagen type I alpha 1 chain (Col1A1), were restored. The binding capacity of TET3 to the Col1A1 promoter could be enhanced by the inhibition of miR-29a. Finally, deletion of TET3 rescued the inhibitory effect of the miR-29a antagomir on the proliferation of decidualized ESCs in vitro and embryo implantation in vivo. Thus, loss of miR-29a causes implantation failure because of the limitation of ESCs decidualization-related changes in non-receptive endometrium during early pregnancy. Loss of miR-29a inhibits decidualization of ESCs TET3 demethylates the Col1A1 promoter Loss of miR-29a enhances the binding capacity of TET3 to the Col1A1 promoter Loss of miR-29a suppresses embryo implantation during early pregnancy in mice

Abstract
Extracellular vesicles (EVs) secreted from tumor-associated macrophages (TAMs) are known to generate an immune-suppressive environment conducive to the development of ovarian cancer (OC). We tried to elucidate the role of TAM-derived exosomal microRNA (miR)-29a-3p in OC. miR-29a-3p, forkhead box protein O3 (FOXO3), and programmed death ligand-1 (PD-L1) expression was determined and their interactions evaluated. EVs were isolated, followed by determination of the uptake of EVs by OC cells, after which the proliferation and immune escape facilities of the OC cells were determined. OC xenograft models were constructed with EVs in correspondence with in vivo experiments. Overexpressed miR-29a-3p was detected in OC, and miR-29a-3p promoted OC cell proliferation and immune escape. EVs derived from TAMs enhanced the proliferation of OC cells. miR-29a-3p was enriched in TAM-EVs, and TAM-EVs delivered miR-29a-3p into OC cells. Downregulated FOXO3 was identified in OC, whereas miR-29a-3p targeted FOXO3 to suppress glycogen synthase kinase 3β (GSK3β) activity via the serine/threonine protein kinase (AKT)/GSK3β pathway. Inhibition of TAM-derived exosomal miR-29a-3p decreased PD-L1 to inhibit OC progression through the FOXO3-AKT/GSK3β pathway in vitro and in vivo. Taken together, the current studies highlight the FOXO3-AKT/GSK3β pathway and the mechanism by which TAM-derived exosomal miR-29a-3p enhances the expression of PD-L1 to facilitate OC cell proliferation and immune escape.

Abstract
BACKGROUND AND AIMS Increasing evidence in recent years has suggested that microRNA-7 (miR-7) is an important gene implicated in the development of various diseases including HCC. However, the role of miR-7 in autoimmune hepatitis (AIH) is unknown. APPROACH AND RESULTS Herein, we showed that miR-7 deficiency led to exacerbated pathology in Concanavalin-A-induced murine acute autoimmune liver injury (ALI) model, accompanied by hyperactivation state of CD4+ T cells. Depletion of CD4+ T cells reduced the effect of miR-7 deficiency on the pathology of ALI. Interestingly, miR-7 deficiency elevated CD4+ T-cell activation, proliferation, and cytokine production in vitro. Adoptive cell transfer experiments showed that miR-7def CD4+ T cells could exacerbate the pathology of ALI. Further analysis showed that miR-7 expression was up-regulated in activated CD4+ T cells. Importantly, the transcription of pre-miR-7b, a major resource of mature miR-7 in CD4+ T cells, was dominantly dependent on transcription factor CCAAT enhancer binding protein alpha (C/EBPα), which binds to the core promoter region of the miR-7b gene. Global gene analysis showed that mitogen-activated protein kinase 4 (MAPK4) is a target of miR-7 in CD4+ T cells. Finally, the loss of MAPK4 could ameliorate the activation state of CD4+ T cells with or without miR-7 deficiency. Our studies document the important role of miR-7 in the setting of AIH induced by Concanavalin-A. Specifically, we provide evidence that the C/EBPα/miR-7 axis negatively controls CD4+ T-cell activation and function through MAPK4, thereby orchestrating experimental AIH in mice. CONCLUSIONS This study expands on the important role of miR-7 in liver-related diseases and reveals the value of the C/EBPα/miR-7 axis in CD4+ T-cell biological function for the pathogenesis of immune-mediated liver diseases.

The role of let-7b in the inhibition of hepatic stellate cell activation by rSjP40. PLoS Negl Trop Dis 2021; 15:e0009472. [PMID: 34161325 PMCID: PMC8221521 DOI: 10.1371/journal.pntd.0009472] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 05/13/2021] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND Hepatic stellate cells (HSCs) are one of the main cell types involved in liver fibrosis induced by many factors, including schistosomes. Previous studies in our lab have shown that recombinant P40 protein from Schistosoma japonicum (rSjP40) can inhibit HSC activation in vitro. Let-7b is a member of the let-7 microRNA family and plays an inhibitory role in a variety of diseases and inflammatory conditions. In this study, we investigated the role of let-7b in the inhibition of HSC activation by rSjP40. METHODS Expression of let-7b was detected by quantitative real-time PCR. A dual luciferase assay was used to confirm direct interaction between let-7b and collagen I. We also used western blot to assess protein levels of TGFβRI and collagen type I α1 (COL1A1). RESULTS We found that rSjP40 up-regulates expression of let-7b in HSCs. Let-7b inhibits collagen I expression by directly targeting the 3'UTR region of the collagen I gene. Furthermore, we discovered that let-7b inhibitor partially restores the loss of collagen I expression caused by rSjP40. CONCLUSION Our research clarifies the role of let-7b in the inhibition of HSC activation by rSjP40 and will provide new insights and ideas for the inhibition of HSC activation and treatment of liver fibrosis.

MicroRNA in dried blood spots from patients with Aagenaes syndrome and evaluation of pre-analytical and analytical factors. Pediatr Res 2021; 89:1780-1787. [PMID: 32932426 DOI: 10.1038/s41390-020-01153-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 08/07/2020] [Accepted: 08/31/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND Circulatory miRNAs are promising biomarkers. The feasibility of using miRNA from dried blood spots (DBS) was investigated using newborn screening cards from patients with cholestasis-lymphedema syndrome (Aagenaes syndrome) and controls. METHODS Total amount of miRNA and specific miRNAs from DBS were analyzed. miRNA was also obtained from newborn screening cards in patients with cholestasis-lymphedema syndrome/Aagenaes syndrome and in healthy newborns. RESULTS No differences in miRNA concentrations were found between multispotted samples and samples with one single drop of blood and between central and peripheral punches. Ten repeated freeze-thaw cycles did not significantly change miRNA levels from controls. miR-299 (1.73-fold change, p = 0.034) and miR-365 (1.46-fold change, p = 0.011) were upregulated and miR-30c (0.72-fold change, p = 0.0037), miR-652 (0.85-fold change, p = 0.025), and miR-744 (0.72-fold change, p = 0.0069) were downregulated in patients with Aagenaes syndrome at birth compared to controls. CONCLUSIONS miRNAs were not affected by multispotting or punch location and were stable throughout repeated freeze-thaw cycles. miRNA in dried blood spots could be used to detect differential expression of miRNA in newborns with Aagenaes syndrome and healthy controls in newborn screening cards. Dried blood spots may be a useful source to explore circulating miRNA as biomarkers. IMPACT Circulating miRNAs can be useful biomarkers. miRNAs from dried blood spots were not affected by multispotting or punch location and were stable throughout repeated freeze-thaw cycles. Discrimination between patients and controls are allowed even with few individuals. Early after birth, patients with cholestasis-lymphedema syndrome exhibit miRNA profiles associated with liver fibrosis. This study demonstrated that newborn screening cards may be a useful source for studying miRNA as the technical variability is smaller than biological variation.

Abstract
Liver fibrosis is a pathological process caused by persistent chronic injury of the liver. Kupffer cells, natural killer (NK) cells, NKT cells, and dendritic cells (DCs), which are in close contact with T and B cells, serve to bridge innate and adaptive immunity in the liver. Meanwhile, an imbalanced inflammatory response constitutes a challenge in liver disease. The dichotomous roles of novel immune cells, including T helper 17 (Th17), regulatory T cells (Tregs), mucosa-associated invariant T cells (MAIT), and innate lymphoid cells (ILCs) in liver fibrosis have gradually been revealed. These cells not only induce damage during liver fibrosis but also promote tissue repair. Hence, immune cells have unique, and often opposing, roles during the various stages of fibrosis. Due to this heterogeneity, the treatment, or reversal of fibrosis through the target of immune cells have attracted much attention. Moreover, activation of hepatic stellate cells (HSCs) constitutes the core of fibrosis. This activation is regulated by various immune mediators, including Th17, Th22, and Th9, MAIT, ILCs, and γδ T cells, as well as their related cytokines. Thus, liver fibrosis results from the complex interaction of these immune mediators, thereby complicating the ability to elucidate the mechanisms of action elicited by each cell type. Future developments in biotechnology will certainly aid in this feat to inform the design of novel therapeutic targets. Therefore, the aim of this review was to summarize the role of specific immune cells in liver fibrosis, as well as biomarkers and treatment methods related to these cells.

Abstract
microRNA are small non-coding RNA molecules which inhibit gene expression by binding mRNA, preventing its translation. As important regulators of gene expression, there is increasing interest in microRNAs as potential diagnostic biomarkers and therapeutic targets. Studies investigating the role of one of the miRNA-miR-652-3p-detail diverse roles for this miRNA in normal cell homoeostasis and disease states, including cancers, cardiovascular disease, mental health, and central nervous system diseases. Here, we review recent literature surrounding miR-652-3p, discussing its known target genes and their relevance to disease progression. These studies demonstrate that miR-652-3p targets LLGL1 and ZEB1 to modulate cell polarity mechanisms, with impacts on cancer metastasis and asymmetric cell division. Inhibition of the NOTCH ligand JAG1 by miR-652-3p can have diverse effects on angiogenesis and immune cell regulation. Investigation of miR-652-3p and other dysregulated miRNAs identified a number of pathways potentially regulated by miR-652-3p. This review demonstrates that miR-652-3p has great promise as a diagnostic or therapeutic target due to its activity across multiple cellular systems.

Abstract
Influenza A virus (IAV) infections result in a large number of deaths and substantial economic losses each year. MicroRNAs repress gene expression and are involved in virus-host interactions. miR-29a is known to have anti-tumor and anti-fibrotic effects. However, the role of miR-29a in IAV infection is unclear. In the present study, we investigated the effect of miR-29a on IAV infection and the mechanisms by which it functions. IAV infection was found to cause decreased miR-29a expression in lung epithelial A549 cells and mouse lungs. Overexpression of miR-29a reduced IAV mRNA and protein levels and progeny virus production in HEK293 and A549 cells. Inhibition of IAV infection by miR-29a was observed with different strains of IAV, including A/PR/8/34, A/WSN/1933, and clinical isolates A/OK/3052/09 and A/OK/309/06 H3N2. Knockout of miR-29a using CRISPR/Cas9 resulted in an increase in viral mRNA and protein levels, confirming that miR-29a suppresses IAV infection. A 3' untranslated region (3'-UTR) reporter assay showed that miR-29a had binding sites in the 3'-UTR of the Wnt-Ca2+ signaling receptor frizzled 5 gene, and overexpression of miR-29a reduced the level of the endogenous frizzled 5 protein. Wnt5a treatment of HEK293 and A549 cells enhanced IAV infection. Our results suggest that miR-29a inhibits IAV infection, probably via the frizzled 5 receptor.

Abstract
BACKGROUND The purpose of this research is to reveal the improvement effect and potential mechanism of Huagan tongluo Fang (HGTLF) on liver fibrosis. METHODS A mouse model of liver fibrosis induced by CCl4 was established to analyze the effect of HGTLF on liver fibrosis. The expression changes of miRNA after HGTLF stimulation were detected by qRT-PCR. After interference with miR-184 in Th17 cells, the concentration of IL-17A in cell culture supernatants was detected by ELISA and the proportion of Th17 cells was analyzed by flow cytometry. The relationship between miR-184 and FOXO1 was verified by online software and dual-luciferase reporter system. After HGTLF treatment of Th17 cells overexpressing miR-184, the protein level of FOXO1 was detected by Western blot. RESULTS HGTLF could significantly improve liver fibrosis in mice. By qRT-PCR, miR-184 was most significantly expressed after HGTLF drug stimulation, and miR-184 was considered to be the major RNA involved in Th17 cell differentiation. Interference with miR-184 in Th17 cells inhibited the differentiation of Th17 cells. By online software and dual-luciferase reporter system assay, the direct interaction of miR-184 with FOXO1 was confirmed. After HGTLF treatment of Th17 cells overexpressing miR-184, FOXO1 protein levels were significantly up-regulated and inhibited the differentiation of Th17 cells, which was reversed by miR-184 inhibitors. The Vivo experiments also confirmed the improvement effect of HGTLF on liver fibrosis in mice. CONCLUSION Our results indicated that HGTLF could improve liver fibrosis via down-regulating miR-184 and up-regulating of FOXO1 to inhibit Th17 cell differentiation.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease and ranges from steatosis to steatohepatitis and to liver fibrosis. Lipotoxicity in hepatocytes, elevated oxidative stress and the activation of proinflammatory mediators of Kupffer cells, and fibrogenic pathways of activated hepatic stellate cells can contribute to the development of NAFLD. MicroRNAs (miRs) play a crucial role in the dysregulated metabolism and inflammatory signaling connected with NAFLD and its progression towards more severe stages. Of note, the protective effect of non-coding miR-29a on liver damage and its versatile action on epigenetic activity, mitochondrial homeostasis and immunomodulation may improve our perception of the pathogenesis of NAFLD. Herein, we review the biological functions of critical miRs in NAFLD, as well as highlight the emerging role of miR-29a in therapeutic application and the recent advances in molecular mechanisms underlying its liver protective effect.

Abstract
Laryngeal cancer (LCa), a neoplasm of the head and neck region, is a leading cause of death worldwide. Surgical intervention remains the mainstay of LCa treatment, but a crucial point is represented by the possible nodal involvement. Therefore, it is urgently needed to develop biomarkers and therapeutic tools able to drive treatment approaches for LCa. In this study, we investigated deregulated microRNAs (miRNAs) in tissues from LCa patients with either lymph node metastases (N+) or not (N−). miRNA expression profiling was performed by a comprehensive PCR array and subsequent validation by RT-qPCR. Results showed a significant decrease of miR-449a expression in N+ compared to N− patients, and miR-133b down-modulation in LCa tissues compared to paired normal ones. Receiver operating characteristic (ROC) curve analysis revealed the potential diagnostic power of miR-133b for LCa detection. According to the validation results, we selected miR-449a for further in vitro studies. Ectopic miR-449a expression in the LCa cell line Hep-2 inhibited invasion and motility in vitro, slowed cell proliferation, and induced the downregulation of Notch1 and Notch2 as direct targets of miR-449a. Collectively, this study provides new promising biomarkers for LCa diagnosis and a new opportunity to use miR-449a for the treatment of nodal metastases in LCa patients.

Abstract
BACKGROUND Hepatic fibrosis is the final endpoint for most chronic liver diseases and remains a significant public health problem worldwide. Icariin, a naturally occurring flavonol glucoside, has been reported to exhibit protective effects on liver injury and alleviate liver fibrosis. However, the underlying detail molecular mechanism is not fully revealed. METHODS Mouse primary hepatic stellate cells (HSCs) and carbon tetrachloride (CCL4 )-induced liver fibrosis model in mice were used as in vitro and in vivo models in this study. The expression levels of miR-875-5p were detected by quantitative reverse transcription-PCR. The validation of the direct target of miR-875-5p was through dual-luciferase reporter assay and western blotting assay. The cell proliferation and cell mobility were determined using MTT assay and Transwell migration assay, respectively. RESULTS We found that icariin inhibited epithelial-mesenchymal transition and collagen protein section of HSCs. Icariin exerted hepatoprotective effects on mice model of CCL4 -induced liver fibrosis. Our further results revealed that miR-875-5p was downregulated in human cirrhosis tissues and activated murine HSCs. Icariin induced miR-875-5p upregulation and subsequently decreased glioma-associated oncogene homolog 1 (GLI1) expression through direct binding to the three prime untranslated region of GLI1 mRNA. CONCLUSION Our study highlighted the potential therapeutic application of icariin for liver fibrosis management.

Abstract
Ischemic stroke is a devastating central nervous disease associated with oxidative stress and NOX2 is the main source of ROS responsible for brain tissue. miRNAs are a class of negative regulator of genes in mammals and involves the pathogenesis of ischemic stroke. This study aims to observe the role of target miRNA(miR-652) of NOX2 in ischemic stroke. A rat cerebral ischemia/reperfusion (CI/R) injury model and an SH-SY5Y cell hypoxia/reoxygenation(H/R) model were used to simulate ischemic stroke, and corresponding gene expression, biochemical indicators and pathophysiological indicators were measured to observe the role of miR-652. NOX2 significantly increased in brain tissues subjected to I/R or in SH-SY5Y cells subjected to H/R, while the expression level of miR-652(potential target of NOX2) significantly decreased in both brain tissues and plasma. Overexpression of miR-652 significantly suppressed NOX2 expression and ROS generation in H/R treated SH-SY5Y cells and reduced the relative luciferase activity of cells transfected with plasmid NOX2-WT (reporter gene plasmid). MiR-652 agomir significantly decreased the expression of NOX2 and ROS generation in brain tissues of CIR rats, as well as tissue injury. These data indicated that miR-652 protected rats from cerebral ischemia reperfusion injury by directly targeting NOX2, is a novel target for ischemic stroke therapy.

Zhou J, Zhou Y, Wang CX. LncRNA-MIAT regulates fibrosis in hypertrophic cardiomyopathy (HCM) by mediating the expression of miR-29a-3p. J Cell Biochem 2019; 120:7265-7275. [PMID: 30548303 DOI: 10.1002/jcb.28001] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Accepted: 10/08/2018] [Indexed: 01/24/2023]
Abstract
AIM This study aimed to investigate the molecular mechanism underlying the fibrosis in hypertrophic cardiomyopathy (HCM). METHOD Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to measure the expression of potentially relevant microRNAs (miRNAs) and long noncoding RNAs (lncRNAs) in patients with HCM suffering from fibrosis and patients with HCM free of fibrosis. In addition, the regulatory relationship between lncRNAs and miR-29a was studied using a luciferase assay. Subsequently, area under the receiver-operating characteristics (ROC) curve (AUC) analysis was conducted to predict the diagnostic value of myocardial infarction-associated transcript (MIAT), miR-29a, H19, and MEG3 in patients with HCM. Finally, the predicted regulatory relationship betwe en miR-29a and MIAT was validated by transfecting cells with different plasmids. RESULT miR-29a and MIAT were differently expressed between the fibrosis (+) HCM group and the fibrosis (-) HCM group, thus establishing a negative relationship between the expression of these two genes. In addition, both MIAT and miR-29a showed the ability to accurately predict the prognosis in patients with HCM. Furthermore, the luciferase activity of wild-type MIAT was evidently suppressed in cells transfected with miR-29a mimics, suggesting that the expression of miR-29a was apparently downregulated in the presence of MIAT. CONCLUSION The results obtained in this study collectively indicated that the MIAT might be associated with the development of fibrosis (+) HCM via negatively regulating the expression of miR-29a.

Shi Z, Liu B, Li Y, Liu F, Yuan X, Wang Y. MicroRNA-652-3p promotes the proliferation and invasion of the trophoblast HTR-8/SVneo cell line by targeting homeobox A9 to modulate the expression of ephrin receptor B4. Clin Exp Pharmacol Physiol 2019; 46:587-596. [PMID: 30839116 DOI: 10.1111/1440-1681.13080] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2018] [Revised: 02/26/2019] [Accepted: 03/01/2019] [Indexed: 12/16/2022]
Abstract
MicroRNAs (miRNAs) are emerging as novel modulators in the pathogenesis of preeclampsia (PE). Multiple miRNAs have been shown to regulate the proliferation and invasion of trophoblast cells, which play a critical role in successful pregnancies. miR-652-3p has been identified as a novel disease-associated miRNA that is dysregulated in various pathological processes. However, whether miR-652-3p is dysregulated in PE and regulates the cellular function of trophoblast cells remains unknown. In the present study, we aimed to investigate the expression pattern of miR-652-3p in PE and explore its potential function in trophoblast cells. Herein, we found that miR-652-3p expression was significantly decreased in the placental tissues of pregnant women with PE. Cellular function experiments showed that overexpression of miR-652-3p promoted the viability, proliferation, and invasion of trophoblast cells in vitro. By contrast, inhibition of miR-652-3p had the opposite effect. Bioinformatics analysis predicted that homeobox A9 (HOXA9), a crucial regulator of trophoblast cell function, was a potential target gene of miR-652-3p. A luciferase reporter assay confirmed that miR-652-3p directly interacted with the 3'-untranslated region of HOXA9. Moreover, miR-652-3p was shown to negatively regulate the expression of HOXA9 and ephrin receptor B4 (EphB4) in trophoblast cells. Notably, overexpression of HOXA9 or EphB4 significantly reversed the regulatory effect of miR-652-3p on proliferation and invasion of trophoblast cells. Taken together, our findings demonstrate that miR-652-3p regulates the proliferation and invasion of trophoblast cells, possibly through targeting HOXA9 and modulating EphB4 expression.

Abstract
MicroRNAs (miRNA) are small non-coding RNAs (∼22 nt in length) that are known as potent master regulators of eukaryotic gene expression. miRNAs have been shown to play a critical role in cancer pathogenesis, and the misregulation of miRNAs is a well-known feature of cancer. In recent years, miR-29 has emerged as a critical miRNA in various cancers, and it has been shown to regulate multiple oncogenic processes, including epigenetics, proteostasis, metabolism, proliferation, apoptosis, metastasis, fibrosis, angiogenesis, and immunomodulation. Although miR-29 has been thoroughly documented as a tumor suppressor in the majority of studies, some controversy remains with conflicting reports of miR-29 as an oncogene. In this review, we provide a systematic overview of miR-29's functional role in various mechanisms of cancer and introspection on the contradictory roles of miR-29.

J Cell Physiol 2018; 233:6693-6704. [PMID: 29323718 DOI: 10.1002/jcp.26469] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2017] [Accepted: 01/05/2018] [Indexed: 02/06/2023]
Abstract
The study aimed to investigate the impact of miR-182 and FOXO1 on S. japonica-induced hepatic fibrosis. Microarray analysis was performed to screen out differential expressed miRNAs and mRNAs. Rat hepatic fibrosis model and human hepatocellular cell line LX-2 were used to study the effect of miR-182 and FOXO1. qRT-PCR and Western blot were used to detect the expression of miR-182, FOXO1 or other fibrosis markers. The targeting relationship between FOXO1 and miR-182 was verified by luciferase reporter assay. Immunohistochemistry or immunofluorescence staining was conducted to detect FOXO1 or α-SMA in rat hepatic tissues. Cell viability and apoptosis were detected by MTT assay and flow cytometry. The expression of PI3K/AKT pathway-related proteins was detected by Western blot. miR-182 was highly expressed in liver fibrosis samples, and FOXO1 expression was negatively correlated with miR-182 expression. After transfection of miR-182, FOXO1 expression was down-regulated, with the results of LX-2 cells proliferation inhibition and apoptosis induction, as well as the aggravation of rat hepatic fibrosis. The expression of p-AKT/AKT and p-S6/S6 was increased, meaning that the PI3K/AKT signal pathway was activated. The results were reversed when treated with Wortmannin (PI3K inhibitor). After transfection of miR-182 inhibitor, FOXO1 expression was up-regulated, LX-2 cell proliferation was inhibited, and apoptosis rate was increased. High-expressed miR-182 and low-expressed FOXO1 promoted proliferation and inhibiting apoptosis on liver fibrosis cells, stimulating the development of S. japonica-induced hepatic fibrosis through feeding back to PI3K/AKT signaling pathway.
