Jo H, Jeoung J, Shim K, Jeoung D. Nur77 Mediates Anaphylaxis by Regulating miR-21a. Curr Issues Mol Biol 2024; 46:3175-3192. [PMID: 38666929 PMCID: PMC11048962 DOI: 10.3390/cimb46040199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2024] [Revised: 04/01/2024] [Accepted: 04/04/2024] [Indexed: 04/28/2024] Open
Abstract
Nur77 belongs to the NR4A subfamily of orphan nuclear hormone receptors. It has been shown to play important roles in metabolism, cancer progression, cellular differentiation, and the regulation of immune process. However, there has yet to be research reporting on the role of Nur77 in allergic inflammations such as anaphylaxis. This study aimed to identify molecules that could mediate allergic inflammations. To this end, we performed RNA sequencing analysis employing bone marrow-derived mast cells (BMMCs). Antigen (DNP-HSA) stimulation increased the expression levels of transcription factors such as Nr4a3 (NOR1), Nr4a1 (Nur77), and Nr4a2 (Nurr1). We focused our study on Nur77. Antigen stimulation increased the expression of Nur77 in a time- and dose-dependent manner in rat basophilic leukemia cells (RBL2H3). The downregulation of Nur77 prevented both antigen-induced increase in β-hexosaminidase activity as well as hallmarks of allergic reactions such as HDAC3, COX2, and MCP1 in RBL2H3 cells. Nur77 was necessary for both passive cutaneous anaphylaxis (PCA) and passive systemic anaphylaxis (PSA). TargetScan analysis predicted that miR-21a would be a negative regulator of Nur77. miR-21a mimic negatively regulated PCA and PSA by inhibiting the hallmarks of allergic reactions. ChIP assays showed that c-JUN could bind to the promoter sequences of Nur77. Antigen stimulation increased the expression of c-JUN in RBL2H3 cells. Altogether, our findings demonstrate the regulatory role played by Nur77-miR-21a loop in allergic inflammations such as anaphylaxis, making this the first report to present the role played by Nur77 in an allergic inflammation. Our results suggest that Nur77 and miR-21 might serve as targets for developing anti-allergy drugs.

MiR-223-3p regulates the eosinophil degranulation and enhances the inflammation in allergic rhinitis by targeting FBXW7. Int Immunopharmacol 2023; 118:110007. [PMID: 36924565 DOI: 10.1016/j.intimp.2023.110007] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Revised: 03/06/2023] [Accepted: 03/06/2023] [Indexed: 03/17/2023]
Abstract
OBJECTIVES MiR-223-3p is a multifunctional microRNA regulated by multiple transcription factors and plays a critical role in inflammation. This paper was designed to investigate the regulatory role and mechanism of miR-223-3p in eosinophils degranulation and allergic rhinitis (AR) inflammation. METHODS OVA sensitized AR mouse model and EOL-1 cells model were established. RT-qPCR and FISH were performed to detect the miR-223-3p expression. ELISA and WB were utilized to evaluate mRNA and protein expression. HE staining and transmission electron microscopy were applied to observe the morphological changes in nasal mucosa. Flow cytometry and immunofluorescence staining were performed to measure the proportion of eosinophils and eosinophilic major basic protein expression. The targeting relationship between miR-223-3p and FBXW7 was verified by bioinformatic analysis and dual-luciferase reporter gene assay. The expression of FBXW7 was detected by immunohistochemistry. RESULTS The level of miR-223-3p in nasal mucosa was significantly up-regulated in AR group. The expression of miR-223-3p, ECP, MBP, and EPO were increased in EOL-1 cells, further increasing the miR-223-3p level could promote the ECP and EPO mRNA expression. Upregulation of miR-223-3p increased eosinophils granule protein expression, aggravated mucosal destruction and enhanced AR inflammation. Luciferase assay verified miR-223-3p directly target the 3'-UTR of FBXW7. In vitro, overexpression of FBXW7 could reverse the increase in MBP expression caused by the up-regulation of miR-223-3p. In vivo, knockdown of FBXW7 could reverse the down-regulation in granule protein level caused by the down-regulation of miR-223-3p, thereby aggravating AR inflammation. CONCLUSION Collected evidence elucidated that miR-223-3p could regulate the eosinophil degranulation and enhances the inflammation in AR by targeting FBXW7. The miR-223-3p/FBXW7 axis may provide a novel approach for AR treatment.

The Role of Noncoding RNA in Airway Allergic Diseases through Regulation of T Cell Subsets. Mediators Inflamm 2022; 2022:6125698. [PMID: 36248190 PMCID: PMC9553461 DOI: 10.1155/2022/6125698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 08/31/2022] [Accepted: 09/23/2022] [Indexed: 11/18/2022] Open
Abstract
Allergic rhinitis and asthma are common airway allergic diseases, the incidence of which has increased annually in recent years. The human body is frequently exposed to allergens and environmental irritants that trigger immune and inflammatory responses, resulting in altered gene expression. Mounting evidence suggested that epigenetic alterations were strongly associated with the progression and severity of allergic diseases. Noncoding RNAs (ncRNAs) are a class of transcribed RNA molecules that cannot be translated into polypeptides and consist of three major categories, microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). Previous studies showed that ncRNAs were involved in the physiopathological mechanisms of airway allergic diseases and contributed to their occurrence and development. This article reviews the current state of understanding of the role of noncoding RNAs in airway allergic diseases, highlights the limitations of recent studies, and outlines the prospects for further research to facilitate the clinical translation of noncoding RNAs as therapeutic targets and biomarkers.

Abstract
Allergic rhinitis and nasal polyps are common otorhinolaryngological diseases. Small extracellular vesicles and microRNAs have recently become major research topics of interest due to their key regulatory roles in cancer, inflammation, and various diseases. Although very detailed and in-depth studies on the pathogenesis and pathophysiology of allergic rhinitis and nasal polyps have been conducted, few studies have assessed the regulatory effects of exosomes and microRNAs on allergic rhinitis and nasal polyps. This paper reviews the studies on small extracellular vesicles and microRNAs in allergic rhinitis and nasal polyps conducted in recent years and focuses on the regulation of small extracellular vesicles and microRNAs in allergic rhinitis and nasal polyps with the aim of providing insights for the future diagnosis and treatment of allergic rhinitis and nasal polyps.

Abstract
To investigate food allergy-tolerance mechanisms induced through allergen-specific immunotherapy we used RNA-Sequencing to measure gene expression in lymph-node-derived dendritic cells from Pru p 3-anaphylactic mice after immunotherapy with glycodendropeptides at 2 nM and 5 nM, leading to permanent tolerance and short-term desensitization, respectively. Gene expression was also measured in mice receiving no immunotherapy (anaphylaxis); and in which anaphylaxis could never occur (antigen-only). Compared to anaphylaxis, the antigen-only group showed the greatest number of expression-changes (411), followed by tolerant (186) and desensitized (119). Only 29 genes changed in all groups, including Il12b, Cebpb and Ifngr1. The desensitized group showed enrichment for genes related to chronic inflammatory response, secretory granule, and regulation of interleukin-12 production; the tolerant group showed genes related to cytokine receptor activity and glucocorticoid receptor binding, suggesting distinct pathways for similar outcomes. We identified genes and processes potentially involved in the restoration of long-term tolerance via allergen-specific immunotherapy, representing potential prognostic biomarkers.

Abstract
Allergic rhinitis (AR) is a type I hypersensitive disease. Long non-coding RNA (lncRNA) SNHG16 acts as an oncogene in a variety of tumors and promotes the occurrence of inflammation in many inflammatory diseases. The study aims to investigate the expression of SNHG16 and its potential biological functions in AR. RT-qPCR results showed that the expression of SNHG16 in AR was up-regulated. The AR cell model was constructed by stimulating primary nasal mucosal epithelial cells from AR patients with IL-13. After knocking down the expression of lncRNA SNHG16, cell apoptosis was detected by flow cytometry, and the expression of inflammatory factors was detected by ELISA. The results showed that SNHG16 promoted cell apoptosis and inflammation. Then, bioinformatics analysis was used to screen miRNAs bound with SNHG16. Luciferase reporter gene assay and RNA pull-down experiment were used to verify the relationship. We found that the expression of miR-106b-5p was down-regulated and leukemia inhibitory factor (LIF) expression was up-regulated in the AR cell model. The expression of phospho-Janus kinase 1 and p-signal transducer and activator of transcription 3 (STAT3) were detected by Western blotting. Silencing the expression of LIF could inhibit the activity of JAK1/STAT3 pathway and further inhibit cell apoptosis and the occurrence of inflammation. Then transfected SNHG16 shRNA alone or together with miR-106b-5p antagomir into the AR cell model, we found that silencing the expression of SNHG16 down-regulated the expression of LIF and inhibited the activity of the JAK1/STAT3 pathway, cell apoptosis, and inflammation. However, miR-106b-5p antagomir weakened its inhibitory effects. The role of SNHG16 in AR was further verified by the ovalbumin-induced AR mouse model in vivo. In conclusion, SNHG16 up-regulates LIF expression by binding with miR-106b-5p, thus promoting the activity of JAK1/STAT3 pathway, and promoting the development of AR. These results provide new targets for the treatment of AR and may help reduce the damage caused by AR.

Abstract
PURPOSE OF REVIEW MicroRNAs (miRNAs) are small noncoding RNA molecules that are considered one of the fundamental regulatory mechanisms of gene expression. They are involved in many biologic processes, such as signal transduction, cell proliferation and differentiation, apoptosis and stress responses. The purpose of this review is to present recent knowledge about the role of miRNAs in asthma and outline possible applications of miRNAs. RECENT FINDINGS A core set of miRNAs involved in asthma includes downregulated let-7 family, miR-193b, miR-375 as well as upregulated miR-21, miR-223, miR-146a, miR-142-5p, miR-142-3p, miR-146b and miR-155. Recently it has been shown that most of the involved miRNAs increase secretion of Th2 cytokines, decrease secretion of Th1 cytokines, promote differentiation of T cells towards Th2 or play a role in hyperplasia and hypertrophy of bronchial smooth muscle cells. The profiles of miRNAs correlate with clinical characteristics, including lung function, phenotype and severity of asthma. SUMMARY Recent publications confirmed crucial regulatory role of miRNAs in the pathomechanism of asthma. Some single miRNAs or their sets hold the promise for their use as asthma biomarkers facilitating diagnosis or prediction of treatment outcomes. They are also possible target of future therapies. The studies in this field are lacking though.

Abstract
MicroRNAs (miRNAs) have been implicated as regulatory molecules that could play a considerable role in the pathogenesis of different diseases including asthma. This work aims at exploring the role of miR-146a and miR- 106b in the pathogenesis of asthma and their association with asthma severity, IgE, and inflammatory cytokines in asthmatic children. Thirty asthmatic children and twenty age-matched healthy children aged 4-17 years old were enrolled. Expression of plasma miR-146a and miR-106b was measured using quantitative real-time PCR. Plasma levels of interleukin-5 (IL-5) and interleukin-13 (IL-13) were assessed using ELISA. Lung functions were measured by Spirometry. MiR-146a and miR-106b were significantly over-expressed in asthmatic children compared to healthy children. A significant positive correlation between total IgE and both miR-146a and miR-106b was found while no significant correlation could be detected between these miRNAs and asthma severity in asthmatic children. Plasma levels of IL-5 and IL-13 were non-significantly higher in asthmatic children compared to healthy children, and there was no significant correlation between them and both miR-146a and miR-106b expressions in the asthmatic children. The aberrant expression of immune-related miRNAs (miR-146a and miR-106b) and inflammatory cytokines (IL-5 and IL-13) among asthmatic children suggest their probable role in asthma pathogenesis.

Abstract
Group 2 innate lymphoid cells (ILC2s) and Th2 type immune response are critically involved in the pathogenesis of allergic rhinitis (AR), and this pathological process is influenced by microRNAs-mediated post-transcriptional regulation. The present study investigated the adaptation and function of miR-155 in AR patients and mouse model. We found that significantly increased miR-155 expression (1.63 ± 0.12 vs. 0.92 ± 0.11 in human, and 1.68 ± 0.15 vs. 1.06 ± 0.06 in mice) and ILC2s activity in nasal mucosa and serum in AR patients and mice. Administration of miR-155 antagomir significantly reduced the activity of ILC2s in nasal mucosa, suppressed the production of Th2 cytokines in serum and nasal mucosa, and alleviated the airway inflammation and allergic symptoms in AR mice, while miR-155 agomir increased ILC2s activity and production of Th2 cytokines and induced airway inflammation and allergic symptoms in control mice. Meanwhile, the expression of transcriptional factor c-Maf (0.57 ± 0.05 vs. 0.37 ± 0.04) in nasal mucosa in AR mice, which was significantly recovered by miR-155 antagomir (0.56 ± 0.04). Treatment with miR-155 agomir decreased c-Maf expression in nasal mucosa in control mice. This synchronized with the similar pattern in the current observations that miR-155 regulated Th2 cytokine (IL-4, IL-5, IL-9 and IL-13) production, airway inflammation and allergic symptoms in AR mice. Together, upregulation miR-155 suppressed the expression of transcriptional factor c-Maf and was critically involved in the ILC2s activation, which contributed to the airway inflammation and allergic symptoms in AR.

Abstract
RNA transcripts that not undergo translation into polypeptides recently came into focus of research. Long non-coding RNAs (lncRNAs), microRNAs (miRNAs) and circular RNAs (circRNAs) comprise the most important groups of these transcripts. LncRNAs have a length over 200 nucleotides and like mRNAs, have regulated transcription in a tissue specific manner. Biogenesis and function of lncRNAs is related to cell differentiation, response to stimuli and regulation of immune responses. LncRNAs can interact with both miRNAs and mRNAs. MiRNAs are characterized by a length of 22-24 nucleotides. MiRNAs regulate expression of genes at the post-transcriptional level. LncRNAs together with miRNAs are considered as regulators of the immune system. Alterations in their biogenesis is an important mechanism in the development immune related disorders. CircRNAs are products of aberrant maturation of protein-coding transcripts in a process of back-splicing, in which a single strand RNA molecule attains a closed circle shape. Despite a low expression, some circRNA were found to titrate miRNAs and interfere with maturation of legitimate protein-coding transcripts. We summarize the current knowledge on the role of non-coding transcripts in allergic disorders: asthma, atopic dermatitis, allergic rhinitis and urticaria. The reviewed data suggest lncRNA and miRNAs as therapeutic targets and biomarkers of allergic disorders.

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that are 18-22 nucleotides long and highly conserved throughout evolution. Currently, they are considered one of the fundamental regulatory mechanisms of genes expression. It has been demonstrated that miRNAs are involved in many biologic processes, such as signal transduction, cell proliferation and differentiation, apoptosis and stress responses. More recently, the role of miRNA has also been revealed in numerous immunological and inflammatory disorders, including allergic inflammation. Specific miRNA profiles were demonstrated in asthma, allergic rhinitis and atopic dermatitis. A core set of miRNAs involved in atopic diseases include upregulated miR-21, miR-223, miR-146a, miR-142-5p, miR-142-3p, miR-146b, miR-155 and downregulated let-7 family, miR-193b and miR-375. Most of the involved miRNAs increase secretion of Th2 cytokines (miR-1248, miR-146b), decrease secretion of Th1 cytokines (miR-513-5p, miR-625-5p) or promote differentiation of T cells towards Th2 (miR-21, miR-19a). In asthma miR-140-3p, miR-708 and miR-142-3p play a role in hyperplasia and hypertrophy of bronchial smooth muscle cells. Some single miRNAs or, more probably, their sets hold the promise for their use as biomarkers of atopic diseases. They are also promising target of future therapies.

Abstract
Allergic rhinitis is thought to be an allergic disease associated with immunoglobulin (Ig)E-mediated immune response, characterized by increased T helper type 2 (Th2) cytokine production, elevated eosinophil levels in the nasal mucosa and induced nasal secretions. MicroRNA (miRNA) microarray data revealed that the expression level of miR-466a-3p was significantly decreased. Notably, GATA binding protein (GATA-3) was identified as one of its target genes through miRNA target prediction web tools. The expression levels of miR-466a-3p were altered by mimics and lentivirus both in vivo and in vitro, similar to those of GATA-3. Furthermore, the symptoms and histology of allergic rhinitis as well as the levels of serum IgE and interleukin (IL)-4 were examined in different groups of mice. Interestingly, the results for lentiviral miR-466a-3p-treated allergic rhinitis mice were relatively similar to normal mice, compared to allergic rhinitis mice without treatment. Also, miR-466a-3p negatively regulated GATA-3 expression in allergic rhinitis mice, indicating the participant of Th2-cell responses in allergic rhinitis. Taken together, our findings highlight a new perspective on the role of miR-466a-3p in allergic rhinitis. In addition, this study provides a theoretical framework and experimental reference for future research targeting microRNAs as therapeutic targets and diagnostic biomarkers of allergic rhinitis.

Abstract
The increase of both life expectancy of the Western industrialized population and cancer incidence with aging is expected to result in a rapid expansion of the elderly cancer population, including patients with epithelial ovarian cancer (EOC). Although the survival of patients with EOC has generally improved over the past three decades, this progress has yet to provide benefits for elderly patients. Compared with young age, advanced age has been reported as an adverse prognostic factor influencing EOC. However, contradicting results have been obtained, and the mechanisms underlying this observation are poorly defined. Few papers have been published on the underlying biological mechanisms that might explain this prognosis trend. We provide an extensive review of mechanisms that have been linked to EOC prognosis and/or aging in the published literature and might underlie this relationship in humans.

Abstract
Dendritic cells (DCs) are the professional antigen-presenting cells that recognize and present antigens to naïve T cells to induce antigen-specific adaptive immunity. Among the T-cell subsets, T helper type 2 (Th2) cells produce the humoral immune responses required for protection against helminthic disease by activating B cells. DCs induce a Th2 immune response at a certain immune environment. Basophil, eosinophil, mast cells, and type 2 innate lymphoid cells also induce Th2 immunity. However, in the case of DCs, controversy remains regarding which subsets of DCs induce Th2 immunity, which genes in DCs are directly or indirectly involved in inducing Th2 immunity, and the detailed mechanisms underlying induction, regulation, or maintenance of the DC-mediated Th2 immunity against allergic environments and parasite infection. A recent study has shown that a genetic defect in DCs causes an enhanced Th2 immunity leading to severe atopic dermatitis. We summarize the Th2 immune-inducing DC subsets, the genetic and environmental factors involved in DC-mediated Th2 immunity, and current therapeutic approaches for Th2-mediated immune disorders. This review is to provide an improved understanding of DC-mediated Th2 immunity and Th1/Th2 immune balancing, leading to control over their adverse consequences.

Abstract
Allergic inflammation is the foundation of allergic rhinitis and asthma. Although microRNAs are implicated in the pathogenesis of various diseases, information regarding the functional role of microRNAs in allergic diseases is limited. Herein, we reported that microRNA-302e (miR-302e) serves as an important regulator of allergic inflammation in human mast cell line, HMC-1 cells. Our results showed that miR-302e is the dominant member of miR-302 family expressed in HMC-1 cells. Moreover, the expression of miR-302e was significantly decreased in response to phorbol 12-myristate 13-acetate (PMA) and calcium ionophore A23187 or ovalbumin (OVA) stimulation. Overexpression of miR-302e blocked PMA/A23187 or OVA induced the increase in inflammatory cytokines levels, such as IL-1β, IL-6, tumor necrosis factor (TNF)-α and thymic stromal lymphopoietin, while miR-302 inhibition further promoted the release of these cytokines. Mechanistically, we found that miR-302e is a novel miRNA that targets RelA, a gene known to be involved in regulating inflammation, through binding to the 3'-UTR of RelA mRNA. Ectopic miR-302e remarkably suppressed the luciferase activity and expression of RelA, whereas down-regulation of miR-302e increased RelA luciferase activity and expression. Pharmacological inhibition of NF-κB reversed the augmented effect of miR-302e down-regulation on inflammatory cytokines level. Taken together, the present study demonstrates miR-302e limits allergic inflammation through inhibition of NF-κB activation, suggesting miR-302e may play an anti-inflammatory role in allergic diseases and function as a novel therapeutic target for the treatment of these diseases.

Abstract
Objective miRNAs are small, signal-strand, non-coding RNAs that function in post-transcriptional regulation. We analysed the in vivo effect of miR-106b (miR-106b-5p) on inflammatory bone loss in CIA mice. Methods CIA mice are developed by injecting DAB/1 mice with bovine type II collagen containing Freund's adjuvant and then the in vivo effect of miR-106b is examined. On day 22, mice were given lentiviral negative control, lentiviral-mediated miR-106b mimics or lentiviral-mediated miR-106b inhibitor via orbital injection on a weekly basis. Morphological changes in the ankle joints were assessed via micro-CT and histopathology and cytokine expression levels were examined via immunohistochemical staining, ELISA or flow cytometric analysis. miR-106b and osteoclastic-related gene expression was evaluated via quantitative real-time PCR. Results CIA mice were found to have increased miR-106b expression and CIA-associated bone loss and inflammatory infiltration. miR-106b inhibitor treatment markedly decreased arthritis incidence and attenuated bone destruction and histological severity compared with the control group. Moreover, miR-106b inhibitor treatment suppressed RANK ligand (RANKL) expression, increased osteoprotegerin (OPG) expression and reduced the RANKL:OPG ratio in CIA mice. miR-106b inhibition also significantly decreased inflammatory mediator production in joint sections and reduced serum pro-inflammatory cytokine levels when compared with the control group. Additionally, miR-106b inhibition decreased tartrate-resistant acid phosphatase-positive cell numbers and suppressed murine bone marrow macrophage differentiation. Conclusion These findings indicate that miR-106b inhibition can ameliorate CIA-associated inflammation and bone destruction and thus may serve as a potential therapeutic for human RA treatment.

Abstract
Intestinal helminth infections are highly prevalent in the developing world, often resulting in chronic infection and inflicting high host morbidity. With the emergence of drug-resistant parasites, a limited number of chemotherapeutic drugs available and stalling vaccine efforts, an increased understanding of antihelminth immunity is essential to provide new avenues to therapeutic intervention. MicroRNAs are a class of small, nonprotein coding RNAs which negatively regulate mRNA translation, thus providing finite control over gene expression in a plethora of biological settings. The miRNA-mediated coordinated control of gene expression has been shown to be essential in infection and immunity, in promoting and fine-tuning the appropriate immune response. This review gathers together and discusses observations of miRNA-mediated effects on the immune system and the subsequent impact on our understanding of antihelminth immunity.

Abstract
Bisphenol A (BPA), used in polycarbonate plastics and epoxy resins, has a widespread exposure to humans. BPA is of concern for developmental exposure resulting in immunomodulation and disease development due to its ability to cross the placental barrier and presence in breast milk. BPA can use various mechanisms to modulate the immune system and affect diseases, including agonistic and antagonistic effects on many receptors (e.g., estrogen receptors), epigenetic modifications, acting on cell signaling pathways and, likely, the gut microbiome. Immune cell populations and function from the innate and adaptive immune system are altered by developmental BPA exposure, including decreased T regulatory (Treg) cells and upregulated pro- and anti-inflammatory cytokines and chemokines. Developmental BPA exposure can also contribute to the development of type 2 diabetes mellitus, allergy, asthma and mammary cancer disease by altering immune function. Multiple sclerosis and type 1 diabetes mellitus may also be exacerbated by BPA, although more research is needed. Additionally, BPA analogs, such as bisphenol S (BPS), have been increasing in use, and currently, little is known about their immune effects. Therefore, more studies should be conducted to determine if developmental exposure BPA and its analogs modulate immune responses and lead to immune-related diseases.
