Abstract
Asthma is one of the most common chronic non-communicable diseases worldwide, characterized by variable airflow limitation secondary to airway narrowing, airway wall thickening, and increased mucus resulting from chronic inflammation and airway remodeling. Current epidemiological studies reported that hypovitaminosis D is frequent in patients with asthma and is associated with worsening the disease and that supplementation with vitamin D3 improves asthma symptoms. However, despite several advances in the field, the molecular mechanisms of asthma have yet to be comprehensively understood. MicroRNAs play an important role in controlling several biological processes and their deregulation is implicated in diverse diseases, including asthma. Evidence supports that the dysregulation of miR-21, miR-27b, miR-145, miR-146a, and miR-155 leads to disbalance of Th1/Th2 cells, inflammation, and airway remodeling, resulting in exacerbation of asthma. This review addresses how these molecular mechanisms explain the development of asthma and its exacerbation and how vitamin D3 may modulate these microRNAs to improve asthma symptoms.

Abstract
Activation of the epidermal growth factor receptor (EGFR) pathway is involved in the pathogenesis of asthma. Although decades of intensive research have focused on the role of EGFR in asthma, the specific mechanisms and pathways of EGFR signaling remain unclear. Various reports have indicated that inhibition of EGFR improves the pathological features in asthma models. However, extending these experimental findings to clinical applications is difficult. Several measures can be adopted to promote clinical application of EGFR inhibitors. This review focuses on the role of EGFR in the pathogenesis of asthma and the development of a potentially novel therapeutic target for asthma.

Effective Component Compatibility of Bufei Yishen Formula III Which Regulates the Mucus Hypersecretion of COPD Rats via the miR-146a-5p/EGFR/MEK/ERK Pathway. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:9423435. [PMID: 36619199 PMCID: PMC9812609 DOI: 10.1155/2022/9423435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 11/07/2022] [Accepted: 12/12/2022] [Indexed: 12/29/2022]
Abstract
Background The effective-component compatibility of Bufei Yishen formula III (ECC-BYF III) with 5 ingredients (ginsenoside Rh1, astragaloside, icariin, nobiletin, and paeonol) has been shown to protect against chronic obstructive pulmonary disease (COPD). The present study aimed to observe the effects of ECC-BYF III in a COPD rat model and dissect its potential mechanisms in regulating mucus hypersecretion via the miR-146a-5p/epidermal growth factor receptor (EGFR)/MEK/ERK pathway. Methods COPD model rats were treated with normal saline, ECC-BYF III, or N-acetylcysteine (NAC). Pulmonary function, lung tissue histology with H & E and AB-PAS staining, expression levels of interleukin (IL)-4, IL-6, IL-1β, MUC5AC, MUC5B, and FOXA2 in lung tissues and the mRNA and proteins involved in the miR-146a-5p/EGFR/MEK/ERK pathway were evaluated. Results The COPD rats showed a significant decrease in the pulmonary function and serious pathological damage to the lung tissue. ECC-BYF III and NAC significantly improved the ventilation function and small airway pathological damage in the COPD rats. The goblet cells and the expression levels of IL-1β, IL-6, MUC5AC, and MUC5B were increased in the COPD rats and were significantly decreased after ECC-BYF III or NAC intervention. The expression levels of IL-4 and FOXA2 in the COPD rats were markedly decreased and were improved in the ECC-BYF III and NAC groups. ECC-BYF III appeared to have a potent effect in restoring the reduced expression of miR-146a-5p. The increased phosphorylation levels of EGFR, MEK, and ERK1/2 and the protein expression levels of SPDEF in the lungs of COPD rats could be significantly reduced by ECC-BYF III. Conclusions ECC-BYF III has a significant effect in improving the airway mucus hypersecretion in COPD model rats, as well as a protective effect against limited pulmonary function and injured lung histopathology. The protective effect of ECC-BYF III in reducing airway mucus hypersecretion in COPD may involve the miR-146a-5p/EGFR/MEK/ERK pathway.

An Inhibitor of Nuclear Factor-Kappa B Pathway Attenuates the Release of TGF-β1 and Inhibits the Fibrogenic Progress in a Model of Airway Remodeling Induced by Acrolein. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:4984634. [PMID: 35432586 PMCID: PMC9007674 DOI: 10.1155/2022/4984634] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 03/18/2022] [Accepted: 03/22/2022] [Indexed: 12/01/2022]
Abstract
Airway inflammation, airway hypersecretion, and airway remodeling are believed to be involved in the process of lung fibrosis. Nowadays, acrolein is widely used to establish the model of airway remodeling. An active component of propolis, named caffeic acid phenethyl ester (CAPE), is recognized as an inhibitor of the NF-κB pathway and shows anti-inflammatory effect. The purpose of this study was to investigate the protective effect of CAPE on acrolein-induced airway remodeling. 24 mice were divided into 4 groups: control group; acrolein group, mice received acrolein (inhalation of acrolein for 20 days); CAPE group, mice received CAPE (30 mg/kg); and acrolein+CAPE group, mice received acrolein and CAPE. After 20 days, lung tissue was removed for histopathology and immunohistochemical evaluations. TGF-β1 and Muc5ac levels were measured at the protein and molecular levels. Additionally, the phospho-P65/P65 values in the airway smooth muscle cells treated with TGF-β1 or CAPE were detected by Western blot. The results showed that compared with the control, subepithelial collagen deposition, airway inflammation, and peribronchus fibrosis were inhibited in the group treated with CAPE. Furthermore, TGF-β1 was significantly decreased in the acrolein+CAPE group compared with the acrolein group. Additionally, we identified CAPE inhibited P65 phosphorylation. However, CAPE did not inhibit the Muc5ac overproduction and hypersecretion induced by acrolein. In conclusion, as an inhibitor of the NF-κB pathway, CAPE attenuated the release of TGF-β1, which inhibited the fibrogenic progress induced by acrolein in mice and took no effect on inhibiting airway mucus hypersecretion.

Abstract
BACKGROUND Chronic Obstructive Pulmonary Disease (COPD) is a serious public health challenge in the world. According to the treatment instructions by Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2020, bronchiectasis combine with inhaled corticosteroids and long-acting anti-muscarinic agents were recommended as the main prescription. However, this symptomatic treatment still has ineluctable limits because it ignored the most pathogenesis mechanism of COPD. As an alternative traditional Chinese medicine (TCM) for COPD, Bufei Jianpi granules (BJG) can reduce the frequency and duration of acute exacerbation in COPD patients and improve their quality of life. The evidence demonstrated BJG acts as therapeutics that retarding the airway remodeling process, eliminating phlegm, thrombolysis and improving mitochondrial function. However, the detailed molecular mechanism is still urgently revealed. PURPUSE In this study, we aim to find out the active pharmacodynamic ingredients and reveal the treatment mechanism of active pharmacodynamic ingredients. METHODS Based on the pharmacodynamic evaluation and chemomic profiling of BJG in COPD rats, an integrated multi-omics analysis was performed, including molecular networking, metabonomics, proteomics and bioinformatics. Moreover, focus on the active compounds, we verified the molecular core mechanism by molecular biology methods. RESULTS Pachymic acid, shionone, peiminine and astragaloside A was verified as therapeutic agents for improving the condition of COPD by acting on the EGFR, ERK1, PAI-1 and p53 target, respectively. CONCLUSION In this study, our findings indicated that some compounds in BJG alleviates the pathological process of COPD, which is related to regulating lung function, mucus production, pulmonary embolism and energy metabolism and this will be a benefit complementary to GOLD guidelines.

Abstract
Research on inflammatory bowel disease (IBD) has produced mounting evidence for the modulation of microRNAs (miRNAs) during pathogenesis. MiRNAs are small, non-coding RNAs that interfere with the translation of mRNAs. Their high stability in free circulation at various regions of the body allows researchers to utilise miRNAs as biomarkers and as a focus for potential treatments of IBD. Yet, their distinct regulatory roles at the gut epithelial barrier remain elusive due to the fact that there are several external and cellular factors contributing to gut permeability. This review focuses on how miRNAs may compromise two components of the gut epithelium that together form the initial physical barrier: the mucus layer and the intercellular epithelial junctions. Here, we summarise the impact of miRNAs on goblet cell secretion and mucin structure, along with the proper function of various junctional proteins involved in paracellular transport, cell adhesion and communication. Knowledge of how this elaborate network of cells at the gut epithelial barrier becomes compromised as a result of dysregulated miRNA expression, thereby contributing to the development of IBD, will support the generation of miRNA-associated biomarker panels and therapeutic strategies that detect and ameliorate gut permeability.

Abstract
Asthma prevalence has increased considerably over the decades and it is now considered as one of the most common chronic disorders in the world. While the current anti-asthmatic therapies are effective for most asthma patients, there are 5-10% subjects whose disease is not controlled by such agents and they account for about 50% of the asthma-associated healthcare costs. Such patients develop severe asthma (SA), a condition characterized by a dominant Th1/Th17 cytokine response that is accompanied by Type 2 (T2)-low endotype. As JAK (Janus Kinase) signaling is very important for the activation of several cytokine pathways, we examined whether inhibition of JAKs might lessen the clinical and laboratory manifestations of SA. To that end, we employed a recently described murine model that recapitulates the complex immune response identified in the airways of human SA patients. To induce SA, mice were sensitized with house dust mite extract (HDME) and cyclic (c)-di-GMP and then subsequently challenged with HDME and a lower dose of c-di-GMP. In this model, treatment with the JAK inhibitor, Ruxolitinib, significantly ameliorated all the features of SA, including airway hyperresponsiveness and lung inflammation as well as total IgE antibody titers. Thus, these studies highlight JAKs as critical targets for mitigating the hyper-inflammation that occurs in SA and provide the framework for their incorporation into future clinical trials for patients that have severe or difficult-to manage asthma.

Abstract
Na+/H+ exchanger regulatory factor 1 (NHERF1), a class I PDZ-binding protein, regulates G protein-coupled receptor signaling in some cell types. NHERF1 also functions as a scaffolding protein and activates non-G protein-coupled receptor signaling pathways, thereby contributing to the pathogenesis of various diseases. Although we have previously shown that NHERF1 regulates mast cell functions, there is little information regarding the role of NHERF1 in other immune cells. How NHERF1 regulates the pathogenesis of allergic disease such as asthma also remains unknown. In the current study, we show that NHERF1 promotes allergic airway inflammation in a house dust mite extract (HDME)-induced mouse model of asthma. Specifically, HDME-specific serum IgE levels, airway leukocyte numbers, and goblet cell hyperplasia were reduced in NHERF1+/- mice as compared with NHERF1+/+ mice. Interestingly, the gene expression of inflammatory (IL-17a, IL-25, and IL-33) as well as T helper 2 (Th2) cytokines (IL-4, IL-5, and IL-13) and several chemokines that recruit eosinophils, neutrophils, and lymphocytes were also decreased in the lungs of NHERF1+/- mice exposed to HDME. Consistent with these observations, microRNAs regulating mucus production, inflammation, Th2 effector functions, and IL-13 expression were increased in the lungs of HDME-treated NHERF1+/- mice. Overall, our studies reveal a unique role for NHERF1 in regulating asthma pathogenesis, and further elucidation of the mechanisms through which NHERF1 modulates allergic inflammation will lead to the development of new therapeutic strategies for asthma.

Abstract
MicroRNA-145-5p (miR-145-5p) is expressed in a variety of tumors, but the mechanism underlying miR-145-5p in tongue squamous cell carcinoma (TSCC) is not fully understood. Therefore, the present study investigated the role of miR-145-5p in TSCC. miR-145-5p expression levels in TSCC tissues were analyzed via reverse transcription-quantitative PCR. miR-145-5p mimics and inhibitors were transfected into SCC9 and Cal27 cells. The stability and invasion of SCC9 and Cal27 cells were analyzed by performing Transwell assays, while PI and Annexin V were used to detect cell apoptosis. Oxidative stress levels of superoxide dismutase, malondialdehyde and glutathione peroxidase were measured via ELISA. PI3K/AKT signaling pathway-associated protein expression levels were evaluated using western blotting. miR-145-5p was consistently downregulated in TSCC tissues compared with healthy tissues. miR-145-5p overexpression decreased cell stability and invasion, but promoted cell apoptosis and oxidative stress. In addition, PI3K, AKT and phosphorylated-AKT expression levels were significantly diminished. The results indicated that miR-145-5p overexpression inhibited SCC9 and Cal27 cell stability and invasion, promoted SCC9 and Cal27 cell apoptosis and oxidative stress, and inhibited the PI3K/AKT signaling pathway. The results of the present study suggested that miR-145 may serve as a molecular marker of TSCC.

Abstract
Identification of matrix-bound nanovesicles (MBV) as ubiquitous components of the extracellular matrix (ECM) raises questions regarding their biologic functions and their potential theranostic application. Unlike liquid-phase extracellular vesicles (e.g., exosomes), MBV are tightly bound to the ECM, which makes their isolation and harvesting more challenging. The indiscriminate use of different methods to harvest MBV can alter or disrupt their structural and/or functional integrity. The objective of the present study was to compare the effect of various MBV harvesting methods upon yield, purity, and biologic activity. Combinations of four methods to solubilize the ECM (collagenase [COL], liberase [LIB], or proteinase K [PK] and nonenzymatic elution with potassium chloride) and four isolation methods (ultracentrifugation, ultrafiltration [UF], density barrier, and size exclusion chromatography [SEC]) were used to isolate MBV from urinary bladder-derived ECM. All combinations of solubilization and isolation methods allowed for the harvesting of MBV, however, distinct differences were noted. The highest yield, purity, cellular uptake, and biologic activity were seen with MBV isolated by a combination of liberase or collagenase followed by SEC. The combination of proteinase K and UF was shown to have detrimental effects on bioactivity. The results show the importance of selecting appropriate MBV harvesting methods for the characterization and evaluation of MBV and for analysis of their potential theranostic application. Impact statement Identification of matrix-bound nanovesicles (MBV) as ubiquitous components of the extracellular matrix (ECM) has raised questions regarding their biologic functions and their potential theranostic application. This study demonstrates that the harvesting methods used can result in samples with physical and biochemical properties that are unique to the isolation and solubilization methods used. Consequently, developing harvesting methods that minimize sample contamination with ECM remnants and/or solubilization agents will be essential in determining the theranostic potential of MBV in future studies.

Abstract
MicroRNAs (miRNAs) are short single-stranded RNAs that have pivotal roles in disease pathophysiology through transcriptional and translational modulation of important genes. It has been implicated in the development of many diseases, such as stroke, cardiovascular conditions, cancers and inflammatory airway diseases. There is recent evidence that miRNAs play important roles in the pathogenesis of asthma and chronic obstructive pulmonary disease (COPD), and could help to distinguish between T2-low (non-eosinophilic, steroid-insensitive) versus T2-high (eosinophilic, steroid-sensitive) disease endotypes. As these are the two most prevalent chronic respiratory diseases globally, with rising disease burden, miRNA research might lead to the development of new diagnostic and therapeutic targets. Research involving miRNAs in airway disease is challenging because: (i) asthma and COPD are heterogeneous inflammatory airway diseases; there are overlapping but distinct inter- and intra-disease differences in the immunological pathophysiology, (ii) there exists more than 2000 known miRNAs and a single miRNA can regulate multiple targets, (iii) differential effects of miRNAs could be present in different cellular subtypes and tissues, and (iv) dysregulated miRNA expression might be a direct consequence of an indirect effect of airway disease onset or progression. As miRNAs are actively secreted in fluids and remain relatively stable, they have the potential for biomarker development and therapeutic targets. In this review, we summarize the preclinical data on potential miRNA biomarkers that mediate different pathophysiological mechanisms in airway disease. We discuss the framework for biomarker development using miRNA and highlight the need for careful patient characterization and endotyping in the screening and validation cohorts, profiling both airway and blood samples to determine the biological fluids of choice in different disease states or severity, and adopting an untargeted approach. Collaboration between the various stakeholders - pharmaceutical companies, laboratory professionals and clinician-scientists is crucial to reduce the difficulties and cost required to bring miRNA research into the translational stage for airway diseases.

Abstract
As a chronic airway disease, asthma has two characteristics, tissue remodeling and airway inflammation. This research focused on miR-92a to explore how it works in asthma. We revealed that the expressions of miR-92a were decreased in both serum and lung tissues from ovalbumin-induced asthma mouse. Bioinformatics analysis, quantitative polymerase chain reaction (qPCR) and dual luciferase assay revealed that miR-92a targets MUC5AC, which was linked to mucus hypersecretion in the pulmonary tracts. By injecting miR-92a-mimics into the trachea, both the airway hyper-reactivity and airway inflammation can be alleviated in an asthma mouse model which is induced by ovalbumin. Moreover, the goblet cell phenotype of asthmatic mice is significantly reduced by the action of miR-92a. Furthermore, miR-92a blocked interleukin (IL)-13-induced MUC5AC luciferase activity in 16HBE. Together, upregulation of miR-92a expression in asthmatic mice plays a role in blocking goblet cell metaplasia by targeting MUC5AC, and thus in the treatment of chronic airway diseases, miR-92a can prevent epithelial remodeling, which is a reasonable method.

Abstract
Programmed cell death-ligand 1 (PD-L1) is a glycoprotein that is expressed on the cell surface of both hematopoietic and nonhematopoietic cells. PD-L1 play a role in the immune tolerance and protect self-tissues from immune system attack. Dysfunction of this molecule has been highlighted in the pathogenesis of tumors, autoimmunity, and infectious disorders. MicroRNAs (miRNAs) are endogenous molecules that are classified as small non-coding RNA with approximately 20-22 nucleotides (nt) length. The function of miRNAs is based on complementary interactions with target mRNA via matching completely or incompletely. The result of this function is decay of the target mRNA or preventing mRNA translation. In the past decades, several miRNAs have been discovered which play an important role in the regulation of PD-L1 in various malignancies. In this review, we discuss the effect of miRNAs on PD-L1 expression and consider the effect of miRNAs on the synthetic pathway of PD-L1, especially during cancers.

Abstract
Characteristic of allergic asthma, CD4+Th2 lymphocytes secrete Th2 cytokines, interleukin (IL)-4, IL-13, and IL-5 that mediate the inflammatory immune response. Surface expression of CD2 and its ligand, CD58, is increased on the monocytes and eosinophils of asthma patients, which correlate with elevated serum IgE levels, suggesting that CD2 may contribute to allergic airway inflammation. Using a murine model of asthma, we observed that house dust mice extract (HDME)-exposed Balb/c mice have increased airway hyperresponsiveness (AHR), lung inflammation, goblet cell hyperplasia, and elevated levels of Th2 cytokines in the lungs, as well as increased serum IgE levels as compared to the control mice. In contrast, with the exception of serum IgE levels, all the other parameters were significantly reduced in HDME-treated Cd2 -/- mice. Interestingly, Il13 but not Il4 or Il5 gene expression in the lungs was dramatically decreased in HDME-exposed Cd2 -/- mice. Of note, the gene expression of IL-13 downstream targets (Muc5b and Muc5ac) and high affinity IL-13Rα2 were upregulated in the lungs of HDME-exposed Balb/c mice but were significantly reduced in HDME-exposed Cd2 -/- mice. Consistently, gene expression of microRNAs regulating mucin production, inflammation, airway smooth muscle cell proliferation and IL-13 transcripts were increased in the lungs of HDME-exposed Cd2 -/- mice. Given the established role of IL-13 in promoting goblet cell hyperplasia, lung inflammation and AHR in allergic asthma, our studies reveal a unique role for CD2 in the regulation of Th2-associated allergic asthma.

Airway inflammation and remodeling of cigarette smoking exposure ovalbumin-induced asthma is alleviated by CpG oligodeoxynucleotides via affecting dendritic cell-mediated Th17 polarization. Int Immunopharmacol 2020; 82:106361.

Abstract
Cigarette smoking (CS) is common in asthma, aggravating inflammatory reactions. However, the current treatment strategies for asthma are still not effective enough, and novel therapeutic approaches are required for CS-induced asthmatic disorders. We here investigated the ability of CpG oligodeoxynucleotides (CpG-ODNs) to inhibit airway inflammation and remodeling in ovalbumin (OVA)-associated asthma in mice exposed to chronic CS, revealing potential mechanistic insights. Lung tissue specimens were histologically analyzed. Th1/Th2/Th17 associated cytokines in serum, bronchoalveolar lavage fluid (BALF), and lung specimens were quantitated by ELISA, qRT-PCR and immunoblot. Parameters of bone marrow-derived dendritic cells (BMDCs) functions were evaluated as well. The results showed that BALB/c mice after CS and OVA treatments developed an asthmatic phenotype with airway inflammation involving both eosinophils and neutrophils, goblet cell metaplasia, airway remodeling, and elevated OVA-specific serum IgE, serum IL-17A, and BALF Th17/Th2 associated cytokines. CpG-ODNs and budesonide were found to synergistically inhibit inflammatory cell recruitment in the lung, airway remodeling, IgE synthesis, and Th17/Th2 associated cytokines. Mechanistically, CpG-ODNs and budesonide acted synergistically on BMDCs via downregulation of TSLP receptor (TSLPR) and IL-23 production, and subsequently contributed to dampen Th17/Th2 polarization in CS-associated asthma. In conclusion, combined administration of CpG-ODNs and budesonide, in a synergistic manner, inhibits airway inflammation, and tissue remodeling mediated by BMDCs by regulating IL-23 secretion and blocking TSLP signaling, which subsequently contribute to alleviate Th17/Th2 imbalance in CS-associated asthma.

Abstract
Asthma is a chronic lung inflammatory disease with high incidence. MicroRNA-192-5p (miR-192-5p) was down-regulated in asthmatics. However, the role of miR-192-5p in asthma is still unclear. In current study, in vitro, the overexpression of miR-192-5p, matrix metalloproteinase (MMP)-16 and autophagy related 7 (ATG7) was conducted in airway smooth muscle cells (ASMCs). We found that miR-192-5p suppressed cell proliferation, and decreased MMP-16 and ATG7 expression. MMP-16 and ATG7 promoted cell proliferation, and further alleviated the down-regulation of miR-192-5p on proliferation of ASMCs. in vivo, miR-192-5p was down-regulated in asthma mice, and involved in improvement of asthma mice. MiR-192-5p was demonstrated to alleviate inflammation in asthma mice, including decreasing the level of ovalbumin (OVA)-specific IgE, interleukin (IL)-4, IL-5, IL-13, iNOS and COX-2. Moreover, the attenuation of airway remodeling induced by miR-192-5p in asthma mice were expressed by the reduction of fibroblast growth factor-23 (FGF-23) level, decrease in concentrations of MMP-2 and MMP-9 as well as down-regulation of collagen I deposition. Further, miR-192-5p also caused the suppression of autophagy in asthma mice, exhibiting a decrease in LC3II/I, beclin-1 and ATG7, and an increase in p62. Importantly, MMP-16 and ATG7 were confirmed to be targets of miR-192-5p. Therefore, our results indicate that miRNA-192-5p may attenuate airway remodeling and autophagy in asthma via targeting MMP-16 and ATG7.

Abstract
miRNA are a class of evolutionarily conserved non-coding 19- to 22-nt regulatory RNA. They affect various cellular functions through modulating the transcriptional and post-transcriptional levels of their target mRNA by changing the stability of protein-coding transcripts or attenuating protein translation. miRNA were discovered in the early 1990s, and they have been the focus of new research in both basic and clinical medical sciences. Today, it has become clear that specific miRNA are linked to the pathogenesis of respiratory diseases, as well as cancer and cardiovascular disease. In addition, EV, including exosomes, which are small membrane-bound vesicles secreted by cells, were found to contain various functional miRNA that can be used for diagnostic and therapeutic purposes. As body fluids, such as blood and respiratory secretions, are major miRNA sources in the body, EV carrying extracellular miRNA are considered potentially useful for the diagnosis and assessment of pathological conditions, as well as the treatment of respiratory or other diseases. Although research in the field of lung cancer is actively progressing, studies in other respiratory fields have emerged recently as well. In this review, we provide an update in the topics of miRNA and EV focused on airway inflammatory diseases, such as asthma and COPD, and explore their potential for clinical applications on respiratory diseases.

Abstract
BACKGROUND Airway remodeling is considered an important factor in refractory and uncontrollable asthma. Previous studies have confirmed that anti-nerve growth factor (NGF) antibody can ameliorate airway remodeling. However, whether nebulized inhalation of anti-NGF microspheres (NANM) can inhibit airway remodeling is not clear. The purpose of this study was to investigate the effects of NANM on ovalbumin (OVA)-induced airway remodeling, and the mechanisms involved. METHODS Anti-NGF microspheres were produced using a polymer alloy method. OVA was used to establish a rat model of asthma airway remodeling. Rats were treated with inhalation atomized anti-NGF antibody or NANM. Airway inflammation, airway reactivity, and airway remodeling were measured. Lung tissue P-Smad3 and tumor growth factor (TGF)-β1 mRNA and protein expression were also measured. RESULTS The anti-NGF antibody microsphere encapsulation rate was high, and the release time was long. NANM markedly attenuated OVA-induced airway remodeling, such as collagen deposition, average pulmonary resistance, the WAm/Pbm, WAt/Pbm, and Wcol/Pbm ratios (WAt, bronchial wall area; Pbm, perimeter of basement membrane; WAm, smooth muscle wall area; Wcol, airway collagen fiber area). Compared with the anti-NGF antibody group and the OVA group, the expression of TGF-β1 mRNA, TGF-β1 protein, and P-Smad3 in the NANM group were markedly decreased. CONCLUSIONS NANM ameliorated OVA-induced airway remodeling, partly through regulation of the TGF-β1/Smad3 pathway.

Abstract
The various roles of microRNAs (miRNAs) in the epigenetic regulation of human disease are gaining importance as areas of research, and a better understanding of these roles may identify targets for development of novel therapies for severe asthma. MiRNAs, a class of small non-coding RNAs that serve as post-transcriptional gene repressors, are recognized as critical components in regulating tissue homeostasis. Alteration in miRNA expression disrupts homeostasis and is an underlying mechanism for development of chronic respiratory diseases, including asthma. Differential profiles of miRNA expression are involved in inflammation and remodeling pathogenicity via activating airway structural cells and immune cells and inducing cytokine releases. miRNA action leads to asthma progression from mild to severe stages. Here, current knowledge of the heterogeneous roles of miRNAs in severe asthma, including biological mechanisms underlying Th2 and macrophage polarization, type 2 innate lymphoid cell (ILC2) biology regulation, steroid-resistant asthma phenotype, airway smooth muscle (ASM) dysfunction, and impaired anti-viral innate immune, are reviewed.

Abstract
MicroRNAs (miRNAs) are small yet versatile gene tuners that regulate a variety of cellular processes, including cell growth and proliferation. The aim of this study was to explore how miR-448-5p affects airway remodeling and transforming growth factor-β1 (TGF-β1)-stimulated epithelial-mesenchymal transition (EMT) by targeting Sine oculis homeobox homolog 1 (Six1) in asthma. Asthmatic mice models with airway remodeling were induced with ovalbumin solution. MiRNA expression was evaluated using quantitative real-time polymerase chain reaction. Transfection studies of bronchial epithelial cells were performed to determine the target genes. A luciferase reporter assay system was applied to identify whether Six1 is a target gene of miR-448-5p. In the current study, we found that miR-448-5p was dramatically decreased in lung tissues of asthmatic mice and TGF-β1-stimulated bronchial epithelial cells. In addition, the decreased level of miR-448-5p was closely associated with the increased expression of Six1. Overexpression of miR-448-5p decreased Six1 expression and, in turn, suppressed TGF-β1-mediated EMT and fibrosis. Next, we predicted that Six1 was a potential target gene of miR-448-5p and demonstrated that miR-448-5p could directly target Six1. An SiRNA targeting Six1 was sufficient to suppress TGF-β1-induced EMT and fibrosis in 16HBE cells. Furthermore, the overexpression of Six1 partially reversed the protective effect of miR-448-5p on TGF-β1-mediated EMT and fibrosis in bronchial epithelial cells. Taken together, the miR-448-5p/TGF-β1/Six1 link may play roles in the progression of EMT and pulmonary fibrosis in asthma.

Abstract
Mucus hypersecretion by airway epithelium and plugging of the airways are primary reasons of mortality in asthma patients and major causes of asthma disease progression and exacerbation. MUC5AC protein is a major component of airway mucus. MicroRNAs (miRNAs), a class of small noncoding RNAs, have emerged as moderators of MUC5AC production and secretion and are implicated in the pathogenesis of asthma. Recently, miR-330 has been reported to be downregulated in the blood of asthmatic patients, acting as a biomarker for asthma. The role of miR-330 in asthma, however, is unclear. Here, we showed that interleukin (IL)-13 induced MUC5AC secretion and inhibited miR-330 expression in a concentration-dependent manner in human bronchial epithelial cells (HBE16). Upregulation of miR-330 in HBE16 cells inhibited IL-13-induced MUC5AC secretion while, conversely, depletion of endogenous miR-330 exacerbated MUC5AC secretion. Munc18b (Syntaxin-Binding Protein 2; STXBP2) is a limiting component of the exocytic machinery of airway epithelial cells. We identified and validated that Munc18b was a direct target of miR-330 and miR-330 regulated MUC5AC secretion in HBE16 cells by acting directly on the 3'UTR of Munc18b mRNA. Collectively, these data reveal that miR-330 inhibits IL-13-induced MUC5AC secretion in human bronchial epithelial cells by targeting Munc18b, encouraging us to further explore the potential of manipulating miR-330 in treatment of airway diseases with mucus hypersecretion.
