[PMID: 33192200 PMCID: PMC7597564 DOI: 10.1177/1559325820946918] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 06/18/2020] [Accepted: 07/04/2020] [Indexed: 11/17/2022] Open
Abstract
Introduction Osteoarthritis (OA) is associated with deregulation of various miRNAs (miRs). The present study reported protective effect of miR-152 in osteoarthritis. Methods Tissue cartilage tissues of OA and normal subjects were used, rat model of anterior cruciate ligament transection (ACLT) was developed. Cartilage study was done by Safranin O-fast green, histological and immunostaining. The chondrocytes were isolated from tissues and were treated with IL-1β and infected with miR-152 or TCF-4 cloned lentiviral vectors. MTT assay was done for cell viability, apoptosis by Annexin-V-FITC staining. Expressions of proteins by western blot assay. Collagen-II assay was done by immunofluroscent assay. Luciferase activity by dual luciferase reporter assay. Results Upregulation of miR-152 improved viability of chondrocytes, decreased apoptosis and balanced the catabolic and anabolic factors of extracellular matrix in vitro. Injecting miR-152 lentivirus in rats improved articular cartilage in osteoarthritis ACLT rats. Bioinformatics analysis suggested TCF-4 as favorable target gene of miR-152, having binding site on the 3'UTR region of TCF-4 mRNA and inhibited the expression of TCF-4. Osteoarthritis tissue cartilage both from humans and rats showed expression of miR-152 inversely linked with expression of TCF-4. Conclusion Present study concludes miR-152 diminished the progression of osteoarthritis partially by inhibiting the expression of TCF-4.

Abstract
Glycosylation is a sophisticated informational system that controls specific biological functions at the cellular and organismal level. Dysregulation of glycosylation may underlie some of the most complex and common diseases of the modern era. In the past 5 years, microRNAs have come to the forefront as a critical regulator of the glycome. Herein, we review the current literature on miRNA regulation of glycosylation and how this work may point to a new way to identify the biological importance of glycosylation enzymes.

Abstract
BACKGROUND Asthma is a prevailing respiratory disease among children, characterized by allergic airway inflammation, airway remodeling, and airway hyperresponsiveness. Although it is well-known that long non-coding RNAs (lncRNAs) are linked to a variety of human diseases and well-documented, very few studies explore its role in asthma. In this study, we investigate the effects of lncRNA PVT1 on the promotion of airway inflammation and its associated mechanisms. METHODS AND MATERIALS Human small airway epithelial cells (HSAECs) with PVT1 overexpressed or knocked down were constructed, and platelet activating factor (PAF) was used to treat HSAECs to mimic the pathological process of asthma in vitro. The expressions of prostaglandin E2 (PGE2), interleukin-1β (IL-1β), IL-6, and tumor necrosis factor-α (TNF-α) were measured by enzyme-linked immunosorbent assay (ELISA). The expressions of PKC, MyD88, and NF-ĸB were measured by Western blot. Monolayer permeability of HSAECs was also compared within different groups. Luciferase reporter gene assay was employed to detect the targeting relationship between PVT1 and miR-149. RESULTS The knockdown of PVT1 attenuated the levels of inflammatory factors induced by PAF and destruction of cell-barrier function. The overexpression of PVT1 facilitated the pathological development. Additionally, miR-149 was identified as a target microRNA of PVT1, and the overexpression of miR-149 could reverse the effects of PVT1 on PAF-induced HSAECs. CONCLUSION These findings suggest that PVT1 may represent a novel potential target for treatment of asthma.

Abstract
Cartilage matrix remodelling homeostasis is a crucial factor in maintaining cartilage integrity. Loss of cartilage integrity is a typical characteristic of osteoarthritis (OA). Strategies aimed at maintaining cartilage integrity have attracted considerable attention in the OA research field. Recently, a series of studies have suggested dual functions of microRNA-140 (miR-140) in cartilage matrix remodelling. Here, we discuss the significance of miR-140 in promoting cartilage formation and inhibiting degeneration. Additionally, we focused on the role of miR-140 in the chondrogenesis of mesenchymal stem cells (MSCs). Of note, we carefully reviewed recent advances in MSC exosomes for miRNA delivery in OA treatment.

Abstract
Background Osteoarthritis (OA) is one of the most prevalent and degenerative diseases with complicated pathology including articular cartilage degradation, subchondral sclerosis and synovitis. Chondrocytes play a crucial role in maintaining cartilage integrity. Methods Primary chondrocytes were treated with 10 ng/mL IL-1β alone, or pre-treated with 20 μM baicalin for 5 h followed by co-treatment with 20 μM baicalin and 10 ng/mL IL-1β. CCK-8 assay was used to assess cell viability, and cell apoptosis was analyzed by both PI/FITC-Annexin V staining and quantitating apoptosis-related Bcl-2, Bax and cleaved-caspase-3 expression at both protein and mRNA level by Western blotting and qRT-PCR, respectively. Chondrocytes were transfected with miRNA-766-3p mimic and autophagy flux was examined by LC3, Beclin and p62 Western blotting and by Cyto-ID assay to quantify autophagic vacuoles. Results Baicalin treatment decreased the apoptosis rate and the expressions of pro-apoptotic proteins induced by IL-1β, up-regulated anti-apoptotic Bcl-2 expression, and inhibited the degradation of ECM. Baicalin increased autophagy through up-regulating the autophagy markers Beclin-1 expression and LC3 Ⅱ/LC3 Ⅰ ratio and promoting autophagic flux. Contrarily, autophagy inhibition partially alleviated the beneficial effects of baicalin on ECM synthesis and anti-apoptosis in the chondrocytes treated with L-1β. Furthermore, the differential expressional profiles of miR-766-3p and apoptosis-inducing factor mitochondria-associated 1 (AIFM1) were determined in IL-1β and IL-1β + baicalin-treated chondrocytes, and we confirmed AIFM1 was a target of miR-766-3p. MiR-766-3p overexpression suppressed apoptosis and facilitated autophagy and ECM synthesis in the chondrocytes through decreasing AIFM1. Contrarily, silencing of miR-766-3p inhibited chondrocyte autophagy and promoted apoptosis, and this effect could be reversed by AIFM1 silence. Conclusion Baicalin protects human OA chondrocytes against IL-1β-induced apoptosis and the degradation of ECM through activating autophagy via miR-766-3p/AIFM1 axis and serves as a potential therapeutic candidate for OA treatment.

Abstract
Long non-coding RNAs (lncRNAs) are largely involved in the development of osteoarthritis (OA), a chronic and degenerative joint disease. The objective of this paper is to research the functional role and molecular mechanism of lncRNA X inactive specific transcript (XIST) in OA. The levels of XIST, microRNA-149-5p (miR-149-5p), and DNA methyltransferase 3A (DNMT3A) were measured. Cell viability and apoptosis rate were determined. Associated protein levels were examined through Western blot. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were implemented for confirming the target relation. And the role of XIST on OA in vivo was investigated by a rat model. XIST was expressed at a high level in OA cartilage tissues and IL-1β-treated chondrocytes. XIST knockdown promoted cell viability but restrained cell apoptosis and extracellular matrix (ECM) protein degradation in IL-1β-treated chondrocytes. XIST directly targeted miR-149-5p and miR-149-5p down-regulation restored si-XIST-mediated pro-proliferative and anti-apoptotic or ECM degradative effects. DNMT3A was a target gene of miR-149-5p and DNMT3A overexpression ameliorated miR-149-5p-induced promotion of cell viability but repression of apoptosis and ECM degradation. Knockdown of XIST reduced DNMT3A level by motivating miR-149-5p expression. The inhibitory influence of XIST down-regulation on OA evolvement was also achieved by miR-149-5p/DNMT3A axis in vivo. In a word, knockdown of XIST can repress the development of OA by miR-149-5p/DNMT3A axis. This study discovers the XIST/miR-149-5p/DNMT3A axis in regulating OA evolution, which is beneficial for understanding the molecular pathomechanism and can lay a good foundation for targeted therapy of OA treatment.

Abstract
Chronological aging as well as biological aging accelerated by various pathologies such as diabetes and obesity contribute to cardiovascular aging, and structural and functional tissue damage of the heart and vasculature. Cardiovascular aging in humans is characterized by structural pathologic remodeling including cardiac and vascular fibrosis, hypertrophy, stiffness, micro- and macro-circulatory impairment, left ventricular diastolic dysfunction precipitating heart failure with either reduced or preserved ejection fraction, and cardiovascular cell death. Cellular senescence, an important hallmark of aging, is a critical factor that impairs repair and regeneration of damaged cells in cardiovascular tissues whereas autophagy, an intracellular catabolic process is an essential inherent mechanism that removes senescent cells throughout life time in all tissues. Several recent reviews have highlighted the fact that all longevity treatment paradigms to mitigate progression of aging-related pathologies converge in induction of autophagy, activation of AMP kinase (AMPK) and Sirtuin pathway, and inhibition of mechanistic target of rapamycin (mTOR). These longevity treatments include health style changes such as caloric restriction, and drug treatments using rapamycin, the first FDA-approved longevity drug, as well as other experimental longevity drugs such as metformin, rapamycin, aspirin, and resveratrol. However, in the heart tissue, autophagy induction has to be tightly regulated since evidence show excessive autophagy results in cardiomyopathy and heart failure. Here we discuss emerging evidence for microRNA-mediated tight regulation of autophagy in the heart in response to treatment with rapamycin, and novel approaches to monitor autophagy progression in a temporal manner to diagnose and regulate autophagy induction by longevity treatments.

Abstract
Osteoarthritis (OA) is a bone and joint disease characterized by progressive cartilage degradation. In the face of global trends of population aging, OA is expected to become the fourth most common disabling disease by 2020. Nevertheless, the detailed pathogenesis of OA has not yet been elucidated. Noncoding RNAs (ncRNAs), including long noncoding RNAs, microRNAs, and circular RNAs, do not encode proteins but have recently emerged as important regulators of apoptosis and autophagy of chondrocytes, thereby highlighting a potential role in chondrocyte injury leading to OA onset and progression. We here review recent findings on these regulatory roles of ncRNAs to provide new directions for research on the pathogenesis of OA and offer new therapeutic targets for prevention and treatment. This article is categorized under: RNA in Disease and Development > RNA in Disease RNA in Disease and Development > RNA in Development.

Abstract
In the development of the skeleton, the long bones are arising from the process of endochondral ossification (EO) in which cartilage is replaced by bone. This complex process is regulated by various factors including genetic, epigenetic, and environmental elements. It is recognized that DNA methylation, higher-order chromatin structure, and post-translational modifications of histones regulate the EO. With emerging understanding, non-coding RNAs (ncRNAs) have been identified as another mode of EO regulation, which is consist of microRNAs (miRNAs or miRs) and long non-coding RNAs (lncRNAs). There is expanding experimental evidence to unlock the role of ncRNAs in the differentiation of cartilage cells, as well as the pathogenesis of several skeletal disorders including osteoarthritis. Cutting-edge technologies such as epigenome-wide association studies have been employed to reveal disease-specific patterns regarding ncRNAs. This opens a new avenue of our understanding of skeletal cell biology, and may also identify potential epigenetic-based biomarkers. In this review, we provide an updated overview of recent advances in the role of ncRNAs especially focus on miRNA and lncRNA in the development of bone from cartilage, as well as their roles in skeletal pathophysiology.

Abstract
In the cartilage and synovial microenvironment of osteoarthritis (OA) patients, utmost changes are commonly brought upon by the inflammatory cytokines, leading to cellular dysfunction, particularly in chondrocytes. The regulation of chondrogenesis, a key part is played the microRNAs. Thus, the current study aimed to assess the function of miR-20a in osteoarthritis. The miR-20a expression was observed to increase in the tissues of OA cartilage, when compared with tissues of normal cartilage, and enhanced proliferation of chondrocyte was observed in the presence of miR-20a. Moreover, on treating the chondrocytes with LPS (lipopolysaccharide), an increase in miR-20a level was observed. On transfecting with miR-20a inhibitor, inhibition in production of LPS-induced pro-inflammatory cytokines as well as cell apoptosis were seen. The assay for luciferase activity showed that the expression of IκBβ was impeded on being targeted at its 3'-UTR by miR-20a. The transfection of IκBβ and inhibitor of miR-20a repressed the NF-κB pathway activation and chondrocyte cellular apoptosis. An OA model was established for in vivo studies on rats by ACLT (anterior cruciate ligament transection). In conclusion, the results demonstrate an increase in articular cavity inflammation in rats with OA in the presence of miR-20a by targeting on IκBβ and activating the NF-κB signaling pathway.

Abstract
Objective: Recently, many studies have revealed the effect of microRNAs (miRNAs) in knee osteoarthritis (KOA). This study aims to explore the role of miR-140-5p in protective effects and mechanisms of synovial injury of rats with KOA via regulating the TLR4/Myd88/NF-κB signaling pathway. Methods: The models of KOA Wistar rats were established by operation of anterior cruciate ligament transection. Rats were injected with agomir NC or miR-140-5p agomir. MiR-140-5p expression in KOA synovial tissues and synoviocytes was evaluated by reverse transcription quantitative polymerase chain reaction (RT-qPCR). The synoviocytes were transfected with mimics NC sequence and miR-140-5p mimics sequence. The expression of TLR4/Myd88/NF-κB signaling pathway-related proteins was measured by RT-qPCR and western blot analysis. The proliferation and apoptosis of synoviocytes in rats with KOA were evaluated by a string of experiments. The expression levels of inflammatory factors in KOA synovial tissues and synoviocytes were detected. Results: MiR-140-5p was down-regulated in KOA synovial tissues and synoviocytes. Upregulation of miR-140-5p could inhibit the inflammation reaction and the apoptosis of synoviocytes as well as promote proliferation of synoviocytes of rats with KOA. Furthermore, upregulated miR-140-5p could inactivate the TLR4/Myd88/NF-κB signaling pathway in rats with KOA. Conclusion: This study suggests that upregulated miR-140-5p could protect synovial injury by restraining inflammation reaction and apoptosis of synoviocytes in KOA rats via TLR4/Myd88/NF-κB signaling pathway inactivation.

Abstract
Osteoarthritis (OA) is the most common degenerative joint disease. One of the main pathogenic factors of OA is thought to be inflammation. Other factors associated with OA are dysregulation of microRNAs, reduced autophagic activity, oxidative stress, and altered metabolism. microRNAs are small non-coding RNAs that are powerful regulators of gene expression. miR-140-5p is considered a cartilage-specific microRNA, is necessary for in vitro chondrogenesis, has anti-inflammatory properties, and is downregulated in osteoarthritic cartilage. Its passenger strand, miR-140-3p, is the most highly expressed microRNA in healthy cartilage and increases during in vitro chondrogenesis. miR-146a is a well-known anti-inflammatory microRNA. Several studies have illustrated its role in OA and autoimmune diseases. We show that, when human chondrocytes were transfected individually with miR-140-5p, miR-140-3p, or miR-146a prior to stimulation with interleukin-1 beta and tumor factor necrosis-alpha as an inflammatory model of OA, each of these microRNAs exhibited similar protective effects. Mass spectrometry analysis provided an insight to the altered proteome. All three microRNAs downregulated important inflammatory mediators. In addition, they affected different proteins belonging to the same biological processes, suggesting an overall inhibition of inflammation and oxidative stress, enhancement of autophagy, and restoration of other homeostatic cellular mechanisms, including metabolism.

Abstract
Osteoarthritis (OA) is one of the most common bone diseasesas it is reported that the impact of knee osteoarthritis symptomatic form is estimated at 240/100,000 people per year. The inflammation of articular cartilageis thought to be the pathologic drive for development of this disease. HMGB1(high mobility group box-1), a regulatory factor for gene transcription, could stimulate inflammation response. However, theexact regulatory role of HMGB1 in the inflammation of articular cartilage still need to be elucidated. In the current study, we used Quantitative Real-Time PCR(Q-PCR) to detect them RNA levels of Collagen Type II Alpha 1(Col2a1), Aggrecan, MMP3(Matrix Metallopeptidase 3), MMP13, ADAMTs4 and ADAMTs5; Enzyme-Linked Immunosorbent Assay(ELISA) was used to detect the content of IL-1β and calpain protein; Cell apoptosis was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling(TUNEL) assay and flow cytometryanalysis; Western blot and immunofluorescence assays were applied to assess the expression of HMGB1; Lastly autophagic activity was mainly verified by monodansylcadaverine (MDC) staining. Our data revealed that in the early stage of chondrocyte inflammation(3 and 6 h of LPS stimulation), cytosolic HMGB1 attenuated inflammation response by facilitating cell autophagy and preventing cell apoptosis. While in the late stage (24 and 48 h of LPS stimulation), the extracellular HMGB1 stimulated inflammation reaction and contributed to the cartilage destruction in OA.

Abstract
MicroRNAs (miRNAs, miRs) are frequently dysregulated in osteoarthritis (OA), but the role of specific miRNAs in OA remains unclear. In this study, we found that miR-93-5p is underexpressed in human and rat OA-affected cartilage (compared with normal cartilage) as well as in IL-1β-treated chondrocytes. Overexpression of miR-93-5p promoted chondrocyte viability, suppressed chondrocyte apoptosis, and maintained the balance between anabolic and catabolic factors of the extracellular matrix in vitro. Similarly, injection of a miR-93-5p-expressing lentivirus alleviated the destruction of articular cartilage in a rat model of OA (anterior cruciate ligament transection). Furthermore, TCF4 was identified as a direct target gene of miR-93-5p. miR-93-5p directly targeted the 3' untranslated region (3'-UTR) of TCF4 mRNA and repressed TCF4 expression. Overexpression of TCF4 attenuated the effects of miR-93-5p on chondrocyte apoptosis and functions. Finally, analyses of miR-93-5p and TCF4 in OA-affected cartilage tissues revealed that miR-93-5p expression inversely correlated with TCF4 expression. Altogether, these findings indicate that miR-93-5p slows OA progression partially by suppressing TCF4 expression, and this phenomenon may provide novel insights into the function of miRNA in OA.

Abstract
AIMS Previous studies have demonstrated that transcriptional silencing of miRNAs due to DNA hypermethylation is associated with different pathologies. It has also been reported that abnormal expression of miR-140-5p and miR-146a is linked to osteoarthritis (OA) progression. In this study, we investigated the role of DNA methylation on miR-140-5p and miR-146a expression in OA. MAIN METHODS miR-140-5p and miR-146a expression was investigated by qRT-PCR. The methylation status of miR-140 and miR-146a regulatory regions was analyzed using qMSP and bisulfite sequencing analysis. SMAD-3 and NF-kB binding to miR-140 and miR-146a regulatory regions was assessed by ChIP assay and knockdown experiments. OA-related genes' expression was evaluated in 5-AzadC, miRNAs inhibitor and 5-AzadC/miRNAs inhibitor-treated cells. KEY FINDINGS Hypermethylation of specific CpG sites in miR-140 and miR-146a regulatory regions was associated with downregulation of miR-140-5p and miR-146a in OA chondrocytes and synoviocytes, respectively. 5-AzadC-induced miR-140-5p and miR-146a upregulation was observed in OA chondrocytes and synoviocytes. Moreover, we found decreased binding affinity of SMAD-3 and NF-kB transcription factors on the hypermethylated miR-140-5p and miR-146a regulatory regions, respectively. Downregulation of MMP-13 and ADAMTS-5 in 5-AzadC-treated OA chondrocytes was prevented by miR-140-5p inhibitor transfection. Similarly, 5-AzadC-treated OA synoviocytes showed decreased expression of IRAK-1, IL1Β and IL-6, which was reversed following 5-AzadC-/miR-146a inhibitor treatment. SIGNIFICANCE Our results strongly suggest the impact of DNA methylation on miR-140-5p and miR-146a suppression in OA chondrocytes and synoviocytes, contributing to OA pathogenesis.

Abstract
Osteoarthritis (OA) is a chronic joint disease characterized by articular cartilage regression. The etiology of OA is diverse, the exact pathogenesis of which remains unclear. Autophagy is a conserved maintenance mechanism in eukaryotic cells. Dysfunction of chondrocyte autophagy is regarded as a crucial pathogenesis of cartilage degradation in OA. MircoRNAs (miRNAs) are a category of small noncoding RNAs, acting as posttranscriptional modulators that regulate biological processes and cell signaling pathways via target genes. A series of miRNAs are involved in the progression of chondrocyte autophagy and are connected with numerous factors and pathways. This article focuses on the mechanisms of chondrocyte autophagy in OA and reviews the role of miRNA in their modulation. Potentially relevant miRNAs are also discussed in order to provide new directions for future research and improve our understanding of the autophagic network of miRNAs.

Abstract
Degenerative cartilage is the pathology of severe depletion of extracellular matrix components in articular cartilage. In diseases like osteoarthritis, misregulation of microRNAs contributes the pathology and collectively leads to disruption of the homeostasis. In this study chondroitin sulfate/hyaluronic acid/chitosan nanoparticles were prepared and successfully characterized chemically and morphologically. Results demonstrated higher chondroitin sulfate amounts led smaller nanoparticles, but lower surface zeta potential due to high electronegativity. After optimization of chondroitin sulfate amounts regarding size and charge, nanoparticles were loaded with microRNA-149-5p, a therapeutic miRNA downregulated in osteoarthritis, and evaluated focusing on their loading efficiency, release behaviour, cytotoxicity and gene transfection efficiency in vitro. Results showed all nanoparticle formulations were non-toxic and promising gene delivery agents, due to increased levels of microRNA-149-5p and decreased mRNA levels of microRNA's target, FUT-1. Highest gene transfection efficiency was obtained with the nanoparticle formulation which had the highest chondroitin sulfate load and smallest size. In addition, owing to their high chondroitin sulfate cargo, all nanoparticles were reported to enhance chondrogenesis, which was demonstrated by gene expression analysis and sulfated glycosaminoglycan (sGAG) staining. The obtained data suggest that the delivery of microRNA-149-5p via polysaccharide based carriers could achieve collaborative impact in cartilage regeneration and have a potential to enhance osteoarthritis treatment.

Abstract
Sepsis is a systemic inflammatory response syndrome resulting from infection. This study aimed at exploring the role of microRNA-140 (miR-140) in septic mice. Wnt family member 11 (WNT11) was verified to be a target gene of miR-140 after bioinformatic prediction and dual luciferase reporter gene assay. Importantly, miR-140 negatively regulated WNT11. We initially induced the model of sepsis by endotoxin, and then ectopic expression and knockdown experiments were performed to explore the functional role of miR-140 in sepsis. Additionally, cross-sectional areas of muscle fiber, lactic acid production, 3-methylhistidine (3-MH) and tyrosine (Tyr) production in extensor digitorium longus (EDL) muscles, and serum levels of inflammatory factors were examined. The effect of miR-140 on the expression of WNT signaling pathway-related and apoptosis-related factors in skeletal muscle tissue was determined. The experimental results indicated that upregulated miR-140 or silenced WNT11 increased cross-sectional areas of muscle fiber while decreasing lactic acid production, skeletal muscle cell apoptosis [corresponding to downregulated B cell lymphoma 2 (Bcl-2)-associated X protein (Bax) and caspase-3 and upregulated Bcl-2], and the proteolytic rate of Tyr and 3-MH. Also, overexpressed miR-140 or silenced WNT11 reduced inflammation as reflected by decreased serum levels of IL-6, IL-10, and TNF-α. Furthermore, overexpression of miR-140 was shown to suppress the activation of the WNT signaling pathway, accompanied by decreased expression of WNT11, β-catenin, and GSK-3β. Taken together, upregulation of miR-140 could potentially inhibit skeletal muscle lactate release, an indirect measure of glycolysis, and atrophy in septic mice through suppressing the WNT signaling pathway via inhibiting WNT11 expression.

Abstract
MicroRNAs (miRNAs) are short (20-23 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. In recent years, deep sequencing of the transcription is being increasingly utilized with the promise of higher sensitivity for the identification of differential expression patterns as well as the opportunity to discover new transcripts, including new alternative isoforms and miRNAs. In this study, miRNAs from A549 cells treated with/without rapamycin or starvation were subject to genome-wide deep sequencing. A total of 1534 miRNAs were detected from the rapamycin- and starvation-treated A549 cells. Among them, 31 miRNAs were consistently upregulated and 131 miRNAs were downregulated in the treated cells when compared with the untreated cells. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis of the predicted target genes of the most significantly differentially expressed miRNAs revealed that the autophagy-related miRNAs are involved in cancer pathway. Taken together, our findings indicate that the underlying mechanism responsible for autophagy is associated with dysregulation of miRNAs in rapamycin- or starvation-induced A549 cells.

Abstract
Kaempferol is a kind of bioflavonoid exerts diverse pharmacological activities, including anti-apoptotic and anti-inflammatory activities. Kaempferol has been recognized as an effective agent for alleviating the clinical symptoms of osteoarthritis (OA). This study aimed to provide evidence that Kaempferol has potential in the management of OA. Lipopolysaccharide (LPS) stimulation induced a significant cell death and inflammatory injury in ATDC5 cells, as evidenced by the decreased cell viability, the induced apoptosis, the activated caspase-3, and the excessive production of IL-6, IL-8 and TNF-α. Precondition of cells with Kaempferol prevented apoptosis and the release of proinflammatory cytokines triggered by LPS. miR-146a was down-regulated by Kaempferol treatment, and Decorin was up-regulated by miR-146a overexpression. Consistently, both silence of miR-146a and Decorin exhibited Kaempferol-like effects towards ATDC5 cells stimulated by LPS. Moreover, Decorin silence activated PI3K/AKT/mTOR signaling pathway. In rat model of OA, the expression of miR-146a and Decorin in cartilage tissues was repressed by Kaempferol. Also, the activated PI3K/AKT/mTOR signaling pathway in OA animal model was enhanced by Kaempferol administration. These data suggested that Kaempferol exerted potential anti-OA effects through down-regulation of miR-146a, and thus repressing the expression of Decorin.

Abstract
Temporomandibular joint osteoarthritis (TMJ-OA), mainly exhibit extracellular matrix loss and condylar cartilage degradation, is the most common chronic and degenerative maxillofacial osteoarthritis; however, no efficient therapy for TMJ-OA exists due to the poor understanding of its pathological progression. MicroRNA (miR)-140-5p is a novel non-coding microRNAs (miRNAs) that expressed in osteoarthritis specifically. To investigate the molecular mechanisms of miR-140-5p in TMJ-OA, primary mandibular condylar chondrocytes (MCCs) from C57BL/6N mice were treated with interleukins (IL)-1β or transfected with miR-140-5p mimics or inhibitors, respectively. The expression of matrix metallopeptidase (MMP)-13, miR-140-5p, nuclear factor (NF)-kB, Smad3 and transforming growth factor (TGF)-β3 were examined by western blotting or quantitative reverse-transcription polymerase chain reaction (qRT-PCR). The interaction between the potential binding sequence of miR-140-5p and the 3'-untranslated region (3'UTR) of Smad3 mRNA was testified by dual-luciferase assay. Small Interfering RNA of Smad3 (Si-Smad3) was utilized to further identify the role of Smad3 mediated by miR-140-5p. The data showed MMP13, miR-140-5p and NF-kB increased significantly in response to IL-1β inflammatory response in MCCs, meanwhile, Smad3 and TGF-β3 reduced markedly. Moreover, transfection of miR-140-5p mimics significantly suppressed the expression of Smad3 and TGF-β3 in MCCs, while miR-140-5p inhibitors acted in a converse manner. As the luciferase reporter of Smad3 mRNA observed active interaction with miR-140-5p, Smad3 was identified as a direct target of miR-140-5p. Additionally, the expression of TGF-β3 was regulated upon the activation of Smad3. Together, these data suggested that miR-140-5p may play a role in regulating mandibular condylar cartilage homeostasis and potentially serve as a novel prognostic factor of TMJ-OA-like pathology.

Abstract
BACKGROUND This study aimed to investigate the change of circulating miRNA expression profiles in knee osteoarthritis (OA) patients before and after celecoxib treatment. METHODS Two hundred and eighteen knee OA patients underwent celecoxib treatment for 6 weeks were enrolled. Plasma samples were obtained at baseline (W0) and at W6, and treatment efficacy were assessed by WOMAC index. In the exploration stage, miRNA expression profiles in plasma before and after treatment from 6 patients were detected by microarray. Subsequently, in the validation stage, 10 top differentially expressed miRNAs (DEMs) after and before treatment in microarray were further validated in all 218 patients by qPCR. RESULTS In the exploration stage, patients after treatment could be distinguished from them before treatment by miRNAs expression profiles by PCA plot and heatmap analysis, and 45 up-regulated and 48 down-regulated miRNAs were identified by volcano plot. In the validation stage, miR-126-5p and miR-320a levels increased at W6 compared to W0, while miR-155-5p and miR-146a-5p levels decreased. WOMAC pain/stiffness/physical function scores were all decreased at W6 compared to W0, and 71% of patients achieved clinical response. The increase of miR-126-5p expression (W6-W0) in clinical responders was much larger compared to nonclinical responders. And miRNA-320a level declined in nonclinical responders while increased in clinical responders. Conversely, miRNA-146a-5p level increased in nonclinical responders while decreased in clinical responders. CONCLUSION Circulating miRNA expression profiles act as important roles in knee OA patients underwent celecoxib treatment, and miR-126-5p, miR-320a as well as miR-146a-5p might correlate with treatment response to celecoxib.

Abstract
Osteoarthritis (OA) is a chronic joint disease and hard to cure at present. Accumulating evidence suggests long noncoding RNA-HOTAIR (lncRNA-HOTAIR) plays important role in OA progression. However, the underlying molecular mechanism of HOTAIR in OA progression has not been well elucidated. In the present study, we identified that HOTAIR level was upregulated in OA cartilage tissues. High expression of HOTAIR was correlated with modified Mankin scale, extracellular matrix (ECM) degradation and chondrocytes apoptosis. The expression of miR-17-5p was down-regulated, while alpha-1, 2 fucosyltransferase 2 (FUT2) was increased in OA progression. Luciferase reporter and RNA immunoprecipitation (RIP) assays indicated that HOTAIR could directly bind to miR-17-5p and indirectly upregulate FUT2 level. Functional investigation revealed HOTAIR and FUT2 aggravated ECM degradation and chondrocytes apoptosis, and this effect could be reversed by miR-17-5p. Altered FUT2 modulated the activity of wnt/β-catenin pathway and HOTAIR/miR-17-5p also mediated wnt/β-catenin pathway through FUT2. Collectively, our findings indicated that HOTAIR/miR-17-5p/FUT2 axis contributed to OA progression via wnt/β-catenin pathway, which might provide novel insights into the function of lncRNA-driven in OA.

Abstract
Osteoarthritis (OA) is a highly prevalent disease, which is associated with extracellular matrix degradation and cell death in articular cartilage. The aim of the present study was to identify whether tetrahydrohyperforin (IDN5706) ameliorates the degeneration of articular cartilage and affects autophagy in OA. The rat model of experimental OA was induced by intra-articular injection of collagenase solution. IDN5706 was administered intragastrically to rats for 6 weeks. Histopathological changes in articular cartilage were examined using hematoxylin and eosin (H&E) and safranin O staining, and Mankin scoring systems. The effect of IDN5706 on autophagy was examined using western blotting. ELISA was performed to detect cartilage inflammation. H&E and safranin O staining, Mankin scores, and electron microscopy indicated that IDN5706 could lessen the degeneration of articular cartilage in OA rats. In addition, western blotting revealed that IDN5706 treatment may activate the suppressed autophagy in OA rats. In conclusion, the present study demonstrated that IDN5706 was able to reduce the severity of experimental OA, alleviate the degeneration of articular cartilage, and affect autophagy in OA model rats.
