Hyaluronic Acid Oligosaccharide Derivatives Alleviate Lipopolysaccharide-Induced Inflammation in ATDC5 Cells by Multiple Mechanisms. Molecules 2022; 27:molecules27175619. [PMID: 36080383 PMCID: PMC9457626 DOI: 10.3390/molecules27175619] [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: 05/23/2022] [Revised: 08/14/2022] [Accepted: 08/17/2022] [Indexed: 11/17/2022] Open
Abstract
High molecular weight hyaluronic acids (HMW-HAs) have been used for the palliative treatment of osteoarthritis (OA) for decades, but the pharmacological activity of HA fragments has not been fully explored due to the limited availability of structurally defined HA fragments. In this study, we synthesized a series glycosides of oligosaccharides of HA (o-HAs), hereinafter collectively referred to as o-HA derivatives. Their effects on OA progression were examined in a chondrocyte inflammatory model established by the lipopolysaccharide (LPS)-challenged ATDC5 cells. Cell Counting Kit-8 (CCK-8) assays and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) showed that o-HA derivatives (≤100 μg/mL) exhibited no cytotoxicity and pro-inflammatory effects. We found that the o-HA and o-HA derivatives alleviated LPS-induced inflammation, apoptosis, autophagy and proliferation-inhibition of ATDC5 cells, similar to the activities of HMW-HAs. Moreover, Western blot analysis showed that different HA derivatives selectively reversed the effects of LPS on the expression of extracellular matrix (ECM)-related proteins (MMP13, COL2A1 and Aggrecan) in ATDC5 cells. Our study suggested that o-HA derivatives may alleviate LPS-induced chondrocyte injury by reducing the inflammatory response, maintaining cell proliferation, inhibiting apoptosis and autophagy, and decreasing ECM degradation, supporting a potential oligosaccharides-mediated therapy for OA.

Abstract
Chitosan (CHIT) and hyaluronic acid (HA) are two polysaccharides (PSs) with high value in several biomedical applications. In this study, we present a microfluidic method to synthetize CHIT-HA NPs to overcome the disadvantages of the dropwise approach generally used for nanoprecipitation of polyelectrolyte complexes. The proposed microfluidic approach enables to generate monodisperse suspensions of NPs with ≈100 nm of size compared to the dropwise method that generated ≈2 times bigger NPs. Finally, we evaluated the potential of obtained NPs in an inflammatory scenario. The treatment with NPs led to the reduction of the main inflammatory molecules produced by macrophages (PGE2, IL-6, IL-8, MCAF and TNF-α) and fibroblasts (IL-1 α, PGE2, TNF-α) stimulated with lipopolysaccharide or conditioned medium, respectively. This study demonstrates that our approach can be used to enhance the synthesis of nanocarriers based on bioactive macromolecules.

Abstract
Involvement of extracellular matrix (ECM) components in aging and age-related neurodegeneration is not well understood. The role of hyaluronan (HA), a major extracellular matrix glycosaminoglycan, in malignancy and inflammation is gaining new understanding. In particular, the differential biological effects of high molecular weight (HMW-HA) and low molecular weight hyaluronan (LMW-HA), and the mechanism behind such differences are being uncovered. Tightly regulated in the brain, HA can have diverse effects on cellular development, growth and degeneration. In this review, we summarize the homeostasis and signaling of HA in healthy tissue, discuss its distribution and ontogeny in the central nervous system (CNS), summarize evidence for its involvement in age-related neurodegeneration and Alzheimer Disease (AD), and assess the potential of HA as a therapeutic target in the CNS.

Abstract
Chondrocyte hypertrophy is one of the key indicators in the progression of osteoarthritis (OA). However, compared with other OA indications, such as cartilage collapse, sclerosis, inflammation, and protease activation, the mechanisms by which chondrocyte hypertrophy contributes to OA remain elusive. As the pathological processes in the OA cartilage microenvironment, such as the alterations in the extracellular matrix, are initiated and dictated by the physiological state of the chondrocytes, in-depth knowledge of chondrocyte hypertrophy is necessary to enhance our understanding of the disease pathology and develop therapeutic agents. Chondrocyte hypertrophy is a factor that induces OA progression; it is also a crucial factor in the endochondral ossification. This review elaborates on this dual functionality of chondrocyte hypertrophy in OA progression and endochondral ossification through a description of the characteristics of various genes and signaling, their mechanism, and their distinguishable physiological effects. Chondrocyte hypertrophy in OA progression leads to a decrease in chondrogenic genes and destruction of cartilage tissue. However, in endochondral ossification, it represents an intermediate stage at the process of differentiation of chondrocytes into osteogenic cells. In addition, this review describes the current therapeutic strategies and their mechanisms, involving genes, proteins, cytokines, small molecules, three-dimensional environments, or exosomes, against the OA induced by chondrocyte hypertrophy. Finally, this review proposes that the contrasting roles of chondrocyte hypertrophy are essential for both OA progression and endochondral ossification, and that this cellular process may be targeted to develop OA therapeutics.

Abstract
It is currently understood that osteoarthritis (OA) is a major chronic inflammatory musculoskeletal disease. While this disease has long been attributed to biomechanical trauma, recent evidence establishes a significant correlation between osteoarthritic progression and unbridled oxidative stress, responsible for prolonged inflammation. Research describes this as a disturbance in the balanced production of reactive oxygen species (ROS) and antioxidant defenses, generating macromolecular damage and disrupted redox signaling and control. Since ROS pathways are being considered new targets for OA treatment, the development of antioxidant therapy to counteract exacerbated oxidative stress is being continuously researched and enhanced in order to fortify the cellular defenses. Experiments with glutathione and its precursor molecule, N-acetylcysteine (NAC), have shown interesting results in the literature for the management of OA, where they have demonstrated efficacy in reducing cartilage degradation and inflammation markers as well as significant improvements in pain and functional outcomes. Glutathione remains a safe, effective and overall cheap treatment alternative in comparison to other current therapeutic solutions and, for these reasons, it may prove to be comparably superior under particular circumstances. METHODS Literature was reviewed using PubMed and Google Scholar in order to bring up significant evidence and illustrate the defensive mechanisms of antioxidant compounds against oxidative damage in the onset of musculoskeletal diseases. The investigation included a combination of keywords such as: oxidative stress, oxidative damage, inflammation, osteoarthritis, antioxidant, glutathione, n-acetylcysteine, redox, and cell signaling. CONCLUSION Based on the numerous studies included in this literature review, glutathione and its precursor N-acetylcysteine have demonstrated significant protective effects in events of prolonged, exacerbated oxidative stress as seen in chronic inflammatory musculoskeletal disorders such as osteoarthritis.

Abstract
In recent years, a growing consensus is emerging that the mechanical microenvironment of tumors is far more critical in the onset of tumor, tumor progression, invasion, and metastasis. Matrix stiffness, one of the sources of mechanical stimulation, affects tumor cells as well as non-tumor cells in multiple different molecular signaling pathways in solid tumors such as colorectal tumors, which lead to tumor invasion and metastasis, immune evasion and drug resistance. This review will illustrate the relationship between matrix stiffness and colorectal cancer from the following aspects. First, briefly introduce the mechanical microenvironment and colorectal cancer, then explain the origin of colorectal cancer extracellular matrix stiffness, and then synthesize the study of matrix stiffness of colorectal cancer in recent years to elaborate the effects of extracellular matrix stiffness in colorectal cancer’s biological behavior and signaling pathways, and finally we will discuss the transformation treatment for the matrix stiffness of colorectal cancer. An in-depth understanding of matrix stiffness and colorectal cancer can help researchers conduct further experiments to find new targets for the treatment of colorectal cancer.

Abstract
Hyaluronan (HA) is an extracellular matrix glycosaminoglycan essential for the homeostasis of cartilage-related tissues. Intracellular adhesion molecule-1 (ICAM-1) and CD44 have been identified as receptors for HA. Recently, transient receptor potential vanilloid 4 (TRPV4) has emerged as a potential research target in several areas of physiology. TRPV4 is a Ca2+-permeable, non-selective cation channel that appears to have mechanosensory or osmosensory roles in several musculoskeletal tissues. HA and TRPV4 play key roles in chondrogenesis; however, it has remained unclear whether they have interactive effects on chondrogenesis and, if so, how do they interact with each other? This study investigated the relationship between HA, its receptors ICAM-1 and CD44, and TRPV4 in the chondrogenic pathway using the ATDC5 cell line. It was found that the presence of HA is required for TRPV4-induced chondrogenesis. Loss of HA suppressed TRPV4-induced expression of the chondrogenic markers, SOX9 and Aggrecan. Moreover, HA affects TRPV4-induced chondrogenic development via each of ICAM-1 and CD44 partially. In conclusion, for the first time, the existence of an interaction between HA, its receptor ICAM-1 and CD44, and TRPV4-activity in chondrogenesis in the ATDC5 cell line was reported. TRPV4 is known to function as a mechanosensory channel in several musculoskeletal tissues. Therefore, findings of this study may suggest the existence of a molecular mechanism that underlies the interactive effects of HA and mechanical loading on joint chondrogenesis.

Abstract
OBJECTIVE Osteoarthritis (OA) is one of the leading causes of disability in the adult population. Common nonoperative treatment options include nonsteroidal anti-inflammatory drugs (NSAIDs), intra-articular corticosteroids, and intra-articular injections of hyaluronic acid (HA). HA is found intrinsically within the knee joint providing viscoelastic properties to the synovial fluid. HA therapy provides anti-inflammatory relief through a number of different pathways, including the suppression of pro-inflammatory cytokines and chemokines. METHODS We conducted a systematic review to summarize the published literature on the anti-inflammatory properties of hyaluronic acid in osteoarthritis. Included articles were categorized based on the primary anti-inflammatory responses described within them, by the immediate cell surface receptor protein assessed within the article, or based on the primary theme of the article. Key findings aimed to describe the macromolecules and inflammatory-mediated responses associated with the cell transmembrane receptors. RESULTS Forty-eight articles were included in this systematic review that focused on the general anti-inflammatory effects of HA in knee OA, mediated through receptor-binding relationships with cluster determinant 44 (CD44), toll-like receptor 2 (TLR-2) and 4 (TLR-4), intercellular adhesion molecule-1 (ICAM-1), and layilin (LAYN) cell surface receptors. Higher molecular weight HA (HMWHA) promotes anti-inflammatory responses, whereas short HA oligosaccharides produce inflammatory reactions. CONCLUSIONS Intra-articular HA is a viable therapeutic option in treating knee OA and suppressing inflammatory responses. HMWHA is effective in suppressing the key macromolecules that elicit the inflammatory response by short HA oligosaccharides.

Abstract
Objective Summarize the biologic effects of Supartz FX for knee osteoarthritis (OA), the first worldwide clinically approved intra-articular (IA) hyaluronic acid (HA) product. Design To determine the mechanism of action from preclinical and clinical studies, a literature search was conducted of Supartz FX using academic databases from 1987 to 2016. Articles on Supartz FX that deal with its mechanisms of action were extracted, categorized, and reviewed. Results Supartz FX has 2 potential mechanisms of action: (1) biomechanical: IA Supartz FX directly improves the viscoelasticity and lubrication of synovial fluid; (2) physiologic: IA Supartz FX penetrates synovium and cartilage tissues to reach HA receptors on the surface of synoviocytes and chondrocytes. In synovium, suppression of gene expression in inflammatory mediators results in improved endogenous HA production, improved properties of synovial fluid, and reduction in pain. In cartilage, suppression of gene expression of collagenases and aggrecanases suppresses cartilage degeneration. Conclusion The net results of basic and clinical studies is that IA Supartz FX provides a more favorable biomechanical and functional environment in the knee joint. Hence, it is not only a lubricant but is also physiologically active. These actions may help explain both short- and long-term improvement in pain and function often achieved from IA Supartz FX in knee OA.

Abstract
OBJECTIVE To explore the effect of hyaluronan oligosaccharides (HAoligos) on interactions between HA and its principal receptor, CD44, in rheumatoid synovial fibroblasts (RSFs) and matrix metalloproteinase (MMP) production. METHODS RSFs were isolated from rheumatoid synovial tissue. HA distribution was visualized by immunocytochemistry. MMP-1 and MMP-3 induction was analyzed by real-time RT-PCR and immunoblotting. The interaction between HAoligos and their MMP-producing receptors was tested by blocking with anti-CD44 and anti-Toll-like receptor 4 (TLR-4). Phosphorylation of nuclear factor κB (NF-κB) and mitogen-activated protein kinase (MAPK) was analyzed by immunoblotting. RESULTS Endogenous HA decreased after treatment with HAoligos, while MMP-1 and MMP-3 expression increased in a dose-dependent manner. Pretreatment with anti-CD44 or anti-TLR-4 antibody significantly reduced the effect of HAoligos on MMP-1 and MMP-3 mRNA expression. NF-κB and p38 MAPK phosphorylation was enhanced by HAoligos pretreated with anti-TLR-4, and HAoligo-induced MMP production was blocked with an inhibitor of NF-κB and p38 MAPK pathways. CONCLUSIONS Disruptive changes in CD44-HA interactions by HAoligos enhanced MMP-1 and MMP-3 production via activation of NF-κB and p38 MAPK signaling pathways in RSFs.

Hyaluronan Inhibits Tlr-4-Dependent RANKL Expression in Human Rheumatoid Arthritis Synovial Fibroblasts. PLoS One 2016; 11:e0153142.

Abstract
The Toll-like receptor (TLR) signaling pathway is activated in synovial fibroblast cells in patients with rheumatoid arthritis (RA). The receptor activator of nuclear factor-κB (RANK) and its ligand, RANKL, are key molecules involved in the differentiation of osteoclasts and joint destruction in RA. Hyaluronan (HA) is a major extracellular component and an important immune regulator. In this study, we show that lipopolysaccharide (LPS) stimulation significantly increases RANKL expression via a TLR-4 signaling pathway. We also demonstrate that HA suppresses LPS-induced RANKL expression, which is dependent on CD44, but not intercellular adhesion molecule-1 (ICAM-1). Our study provides evidence for HA-mediated suppression of TLR-4-dependent RANKL expression. This could present an alternative target for the treatment of destructed joint bones and cartilages in RA.

Abstract
Background Osteoarthritis (OA) is a common joint disease that causes disabilities in elderly. However, few agents with high efficacy and low side effects have been developed to treat OA. In this study, we evaluated the effects of the alginate extract named CTX in OA cell and rabbit models. Results CTX was formulated by hydrolyzing sodium alginate polymers with alginate lyase and then mixing with pectin. HPLC was used to analyze the CTX content. Human chondrosarcoma SW1353 cells treated with interleukin-1β were used as OA model cells to investigate the effects of CTX on chondrocyte inflammation and anabolism. CTX at concentrations up to 1000 μg/ml exerted low cytotoxicity. It inhibited the gene expression of proinflammatory matrix metalloproteinases (MMPs) including MMP1, MMP3 and MMP13 in a dose-dependent manner and increased the mRNA level of aggrecan, the major proteoglycan in articular cartilage, at 1000 μg/ml. Thirteen-week-old New Zealand White rabbits underwent a surgical anterior cruciate ligament transection and were orally treated with normal saline, glucosamine or CTX for up to 7 weeks. Examinations of the rabbit femur and tibia samples demonstrated that the rabbits taking oral CTX at a dosage of 30 mg/kg/day suffered lesser degrees of articular stiffness and histological cartilage damage than the control rabbits. Conclusions The gene expression profiles in the cell and the examinations done on the rabbit cartilage suggest that the alginate extract CTX is a pharmaco-therapeutic agent applicable for OA therapy.

Sorbitol-modified hyaluronic acid reduces oxidative stress, apoptosis and mediators of inflammation and catabolism in human osteoarthritic chondrocytes. Inflamm Res 2014; 63:691-701. [PMID: 24858301 DOI: 10.1007/s00011-014-0742-4] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2013] [Revised: 05/06/2014] [Accepted: 05/08/2014] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVE AND DESIGN Our study was designed to elucidate the precise molecular mechanisms by which sorbitol-modified hyaluronic acid (HA/sorbitol) exerts beneficial effects in osteoarthritis (OA). METHODS Human OA chondrocytes were treated with increasing doses of HA/sorbitol ± anti-CD44 antibody or with sorbitol alone and thereafter with or without interleukin-1beta (IL-1β) or hydrogen peroxide (H2O2). Signal transduction pathways and parameters related to oxidative stress, apoptosis, inflammation, and catabolism were investigated. RESULTS HA/sorbitol prevented IL-1β-induced oxidative stress, as measured by reactive oxygen species, p47-NADPH oxidase phosphorylation, 4-hydroxynonenal (HNE) production and HNE-metabolizing glutathione-S-transferase A4-4 expression. Moreover, HA/sorbitol stifled IL-1β-induced metalloproteinase-13, nitric oxide (NO) and prostaglandin E2 release as well as inducible NO synthase expression. Study of the apoptosis process revealed that this gel significantly attenuated cell death, caspase-3 activation and DNA fragmentation elicited by exposure to a cytotoxic H2O2 dose. Examination of signaling pathway components disclosed that HA/sorbitol prevented IL-1β-induced p38 mitogen-activated protein kinase and nuclear factor-kappa B activation, but not that of extracellular signal-regulated kinases 1 and 2. Interestingly, the antioxidant as well as the anti-inflammatory and anti-catabolic effects of HA/sorbitol were attributed to sorbitol and HA, respectively. CONCLUSIONS Altogether, our findings support a beneficial effect of HA/sorbitol in OA through the restoration of redox status and reduction of apoptosis, inflammation and catabolism involved in cartilage damage.

Abstract
OBJECTIVE To determine the effect of hyaluronic acid (HA) on proteolytic enzymes and bone remodeling mediators induced by interleukin 1β (IL-1β) and related to cartilage catabolism in murine osteoblasts. METHODS Osteoblasts were obtained from Swiss mice and cultured for 3 weeks. HA-treated osteoblasts were incubated with 100 μg/ml HA during the last week of culture, then stimulated with IL-1β (10 ng/ml) for 24 h. The expression of matrix metalloproteinases 3 and 13 (MMP-3 and MMP-13), ADAMTS-4 and ADAMTS-5, tissue inhibitor of metalloproteinases (TIMP), osteoprotegerin, and receptor activator of nuclear factor-κB ligand (RANKL) was determined by real-time polymerase chain reaction. MMP-3 and MMP-13 release was assessed by Western blot analysis. RESULTS IL-1β increased the mRNA levels of MMP-3 and MMP-13 and ADAMTS-4 and ADAMTS-5 and release of MMP-3 and MMP-13. Seven days of HA treatment significantly prevented the IL-1β-increased mRNA levels of MMP-3 (-61%, p < 0.01), MMP-13 (-56%, p < 0.01), ADAMTS-4 (-58%, p < 0.05), ADAMTS-5 (-52%, p < 0.01), and RANKL (-49%, p < 0.05), but not TIMP. As well, IL-1β-induced production of MMP-3 and MMP-13 was inhibited, by 27% (p < 0.01) and 40% (p < 0.01), respectively. CONCLUSION In an inflammatory context in murine osteoblasts, HA can inhibit the expression of MMP and ADAMTS. Because HA can counteract the production of these mediators in chondrocytes, its beneficial effect in osteoarthritis may be due to its action on cartilage and subchondral bone.

Abstract
Synovial fibroblast proliferation is a hallmark of the invasive pannus in the rheumatoid joint. Activated protein C (APC) is a natural anticoagulant that exerts antiinflammatory and cyto-protective effects in various diseases via endothelial protein C receptor (EPCR) and proteinase-activated receptor (PAR)-mediated pathways. In this study, we investigated the effect and the underlying cellular signaling mechanisms of APC on proliferation of human rheumatoid synovial fibroblasts (RSFs). We found that APC stimulated proliferation of mouse dermal fibroblasts (MDFs) and normal human dermal fibroblasts (HDFs) by up to 60%, but robustly downregulated proliferation of RSFs. APC induced the phosphorylation of extracellular signal-regulated protein kinase (ERK) and enhanced expression of p21 and p27 in a dose-dependent manner in RSFs. The latter effect was inhibited by pre-treatment with the ERK inhibitors PD98059 and U0126 but not by p38 inhibitor SB203580. In addition, APC significantly downregulated tumor necrosis factor (TNF)α-stimulated cell proliferation and activation of p38, c-Jun NH2-terminal kinase (JNK) and Akt in RSFs. These results provide the first evidence that APC selectively inhibits proliferation and the inflammatory signaling pathways of RSFs. Thus, APC may reduce synovial hyperplasia and pannus invasion in rheumatoid arthritis.

Abstract
Primary cultured cells derived from normal tissue have a limited lifespan due to replicative senescence and show distinct phenotypes such as irreversible cell cycle arrest and enlarged morphology. Studying senescence-associated genetic alterations in chicken cells will provide valuable knowledge of cellular growth characteristics, when compared with normal and rapidly growing cell lines. Microarray analysis of early- and late-passage (passage 4 and 18, respectively) primary chicken embryo fibroblast (CEF) cells was performed with a 4X44K chicken oligo microarray. A total of 1,888 differentially expressed genes were identified with a 2-fold level cutoff that included 272 upregulated and 1,616 downregulated genes in late-passage senescent CEF cells. Bioinformatic analyses were performed using Ingenuity Pathway Analysis (IPA, http://www.ingenuity.com). Of the 1,888 differentially expressed genes in senescent CEF cells, 458 were identified as functionally known genes and only 61 genes showed upregulation. Because senescent cells generally showed the deactivated states of most cellular mechanisms for proliferation and energy metabolism, intensified analysis on upregulated genes revealed that the molecular mechanisms in senescent CEF cells are characterized by the suppression of cell cycle and proliferation, progression of cell death including apoptosis, and increased expression of various secreting factors. These regulatory pathways may be opposite to those found in the immortal CEF cell line, such as the DF-1 immortal line. Further comparison of differentially expressed genes between senescent and immortal DF-1 CEF cells showed that 35 genes overlapped and were oppositely regulated. The global gene expression profiles may provide insight into the cellular mechanisms that regulate cellular senescence and immortalization of CEF cells.

Abstract
BACKGROUND Crohn's disease is characterized by repeated cycles of inflammation and mucosal healing which ultimately progress to intestinal fibrosis. This inexorable progression toward fibrosis suggests that fibrosis becomes inflammation-independent and auto-propagative. We hypothesized that matrix stiffness regulates this auto-propagation of intestinal fibrosis. METHODS The stiffness of fresh ex vivo samples from normal human small intestine, Crohn's disease strictures, and the unaffected margin were measured with a microelastometer. Normal human colonic fibroblasts were cultured on physiologically normal or pathologically stiff matrices corresponding to the physiological stiffness of normal or fibrotic bowel. Cellular response was assayed for changes in cell morphology, α-smooth muscle actin staining, and gene expression. RESULTS Microelastometer measurements revealed a significant increase in colonic tissue stiffness between normal human colon and Crohn's strictures and between the stricture and adjacent tissue margin. In Ccd-18co cells grown on stiff matrices corresponding to Crohn's strictures, cellular proliferation increased. Pathologic stiffness induced a marked change in cell morphology and increased α-smooth muscle actin protein expression. Growth on a stiff matrix induced fibrogenic gene expression, decreased matrix metalloproteinase, and proinflammatory gene expression and was associated with nuclear localization of the transcriptional cofactor MRTF-A. CONCLUSIONS Matrix stiffness, representative of the pathologic stiffness of Crohn's strictures, activates human colonic fibroblasts to a fibrogenic phenotype. Matrix stiffness affects multiple pathways, suggesting that the mechanical properties of the cellular environment are critical to fibroblast function and may contribute to auto-propagation of intestinal fibrosis in the absence of inflammation, thereby contributing to the intractable intestinal fibrosis characteristic of Crohn's disease.

Abstract
Rheumatoid synovial fibroblasts (RSF) are activated by toll-like receptor (TLR) signaling pathways during the pathogenesis of rheumatoid arthritis (RA). Cathepsin K is highly expressed by RSF, and is known to play a key role in the degradation of type I and type II collagen. Cathepsin K is considered to be implicated in the degradation of bone and cartilage in RA. Recent observations have shown that hyaluronan (HA) is an important inhibitor of inflammation. In the present study, we show that lipopolysaccharide (LPS) stimulation significantly increases cathepsin K expression by real-time PCR and western blotting analysis via a TLR-4 signaling pathway. Furthermore, we demonstrate that HA suppresses LPS-induced cathepsin K expression, which is dependent on CD44 but not intercellular adhesion molecule-1 (ICAM-1) interaction. We also show that HA suppresses LPS-induced matrix metalloproteinase-1 (MMP-1) expression, which is dependent on both CD44 and ICAM-1 interaction. We conclude that the anti-inflammatory effect of HA occurs through crosstalk between more than one HA receptor. Our study provides evidence for HA mediated suppression of LPS-induced cathepsin K and MMP-1 expression, supporting a protective effect of HA in RA.

Abstract
OBJECTIVE This study aimed to examine nuclear factor-κB (NF-κB) activation by a synthetic peptide from type II collagen fragment (CB12-II) and its inhibition by hyaluronan (HA) via its receptors, CD44, and intercellular adhesion molecule-1 (ICAM-1) in chondrocytes. METHODS Osteoarthritic cartilage explants or chondrocytes in monolayer were cultured with CB12-II. Secreted levels of matrix metalloproteinase (MMP)-13 in conditioned media and NF-κB activation in chondrocytes were determined by immunoblotting and enzyme-linked immunosorbent assay (ELISA). Cultures were pretreated with HA to evaluate the inhibitory effect on CB12-II action, and the role of HA receptors in HA effect was investigated using antibodies to CD44 and ICAM-1. RESULTS CB12-II stimulated phosphorylation and nuclear translocation of NF-κB, leading to increased MMP-13 production. HA suppressed NF-κB activation and MMP-13 induction by CB12-II. The individual antibody to CD44 or ICAM-1 partially reversed HA effect on CB12-II action, and both antibodies in combination completely blocked the HA effect. CONCLUSIONS This study clearly demonstrates that CB12-II activates NF-κB for MMP-13 induction and that HA inhibits CB12-II action through interaction with CD44 and ICAM-1 in chondrocytes. HA administration into osteoarthritic joints could suppress the catabolic action of matrix degradation products such as CB12-II as a potent NF-κB inhibitor.

Abstract
The carbohydrate polymer, hyaluronan, is a major component of the extracellular matrix in animal tissues. Exogenous hyaluronan has been used to treat osteoarthritis (OA), a degenerative joint disease involving inflammatory changes. The underlying mechanisms of hyaluronan in OA are not fully understood. Pro-inflammatory interleukin (IL)-1β downregulates peroxisome proliferator-activated receptor gamma (PPARγ), and increases expression of matrix metalloproteinases (MMPs) which are responsible for the degeneration of articular cartilage. The effects of low- and high-molecular-weight hyaluronan (oligo-HA and HMW-HA) on the inflammatory genes were determined in human SW-1353 chondrosarcoma cells. HMW-HA antagonized the effects of IL-1β by increasing PPARγ and decreasing cyclooxygenase (COX)-2, MMP-1, and MMP-13 levels. It promoted Akt, but suppressed mitogen-activated protein kinases (MAPKs) and nuclear factor kappa B (NFκB) signaling, indicating anti-inflammatory effects. In contrast, the cells had overall opposite responses to oligo-HA. In conclusion, HMW-HA and oligo-HA exerted differential inflammatory responses via PPARγ in IL-1β-treated chondrosarcoma cells.

Abstract
For better examination of inflammation, we designed inflammation-targeted nuclear and optical dual-modality contrast agents prepared by I-125 radiolabeling of gold nanorods (GdNRs) conjugated with anti-intercellular adhesion molecule 1 (ICAM-1) antibody. The bioactivity and specific binding of the PEGylated (125)I-ICAM-GdNR conjugates to the ICAM-1 was validated through ELISA testing. Inflammation-targeted imaging was then conducted on an adjuvant-induced arthritic rat model which demonstrated an elevation of ICAM-1 level in the affected ankle joints. Facilitated by the I-125 radioisotope and the whole-body imaging via the Gamma camera, the time-dependent distribution of the systemically injected agent as well as the uptake of the agent in the inflammatory articular tissues could be examined conveniently and quantitatively. The success in targeted delivery of gold nanoparticles to inflammatory tissue enables both nuclear and optical imaging of inflammation at molecular or cellular level. Other than diagnosis, radiolabeled gold nanoparticles also hold promise for targeted therapy of a variety of disorders.

Abstract
In this study, we investigated the mechanisms underlying the anti-inflammatory effects of honokiol in tumor necrosis factor (TNF)-α-stimulated rheumatoid arthritis synovial fibroblasts (RASFs). RASFs pre-treated with honokiol (0-20 μM) were stimulated with TNF-α (20 ng/ml). The levels of prostaglandin E2 (PGE2), nitric oxide (NO), soluble intercellular adhesion molecule-1 (sICAM-1), transforming growth factor-β1 (TGF-β1), monocyte chemotactic protein-1 (MCP-1), and macrophage inflammatory protein-1α (MIP-1α) in supernatants were determined by enzyme-linked immunosorbent assay (ELISA) and Griess assay. In addition, protein expression levels of cyclooxygenase-2 (COX-2), inducible nitric oxide synthase (iNOS), and phosphorylated Akt, nuclear factor kappa B (NFκB), and extracellular signal-regulated kinase (ERK)1/2 were determined by western blot. The expression of NFκB-p65 was assessed by immunocytochemical analysis. TNF-α treatment significantly up-regulated the levels of PGE2, NO, sICAM-1, TGF-β1, MCP-1, and MIP-1α in the supernatants of RASFs, increased the protein expression of COX-2, iNOS, and induced phosphorylation of Akt, IκB-α, NFκB, and ERK1/2 in RASFs. TNF-α-induced expression of these molecules was inhibited in a dose-dependent manner by pre-treatment with honokiol. The inhibitory effect of honokiol on NFκB-p65 activity was also confirmed by immunocytochemical analysis. In conclusion, honokiol is a potential inhibitor of TNF-α-induced expression of inflammatory factors in RASFs, which holds promise as a potential anti-inflammatory drug.

Abstract
BACKGROUND Ischemia/reperfusion injury (IRI) has a negative effect on renal allograft survival. Using a rat model of kidney IRI in this study, we investigated the overall effect of selective c-Jun N-terminal kinase (JNK) inhibitor SP600125 on renal IRI events. METHODS All 45 Fisher rats were anesthetized and renal IRI model was established by 45 min clamp of bilateral renal pedicles and 24 h reperfusion. Vehicle solution or SP600125 solution was intraperitoneally injected 45 min before ischemia, respectively. Analysis of renal histology, function, reactive oxygen species (ROS) expression, JNK phosphorylation status, as well as intra-renal pro-inflammatory cytokines expression was evaluated in this study. RESULTS After IRI, the levels of blood urea nitrogen, creatinine, tissue malondialdehyde, TNF-α, IL-1β, IL-6 were all elevated significantly, while superoxide dismutase, catalase activity were decreased. Histologic findings showed severe devastating lesions and increased rodent cell apoptosis; SP600125 effectively improved morphologic features, reversed above-mentioned parameters, and significantly attenuated c-Jun phosphorylation, as well as intra-renal pro-inflammatory cytokines expression compared with vehicle-treated group. CONCLUSION These data demonstrate that inhibition of c-Jun with SP600125 is capable of attenuating renal IRI, which might be a novel therapy target.

Abstract
Progression to osteoarthritis (OA) is a frequent sequela of severe articular fracture, particularly when weight-bearing joints are involved. Prevention from post-traumatic OA remains a challenge. Hyaluronan (HA) therapy is reported to represent a safe and effective treatment for patients with OA and rheumatoid arthritis. However, the capacity of HA to prevent the occurrence of osteoarthritic changes in fractured joints has not been demonstrated. The present study was undertaken to examine the effects of HA on expression of six OA-related proteins in fibroblast-like synoviocytes (FLS) from 10 patients with tibia plateau fracture. OA-related factors were quantified using a sandwich enzyme-linked immunosorbent assay. Regardless of induction of the FLS with interleukin (IL)-1β, HA was found to down-regulate expression of catabolic factors (IL-1β, matrix metalloproteinase-3, and tumor necrosis factor-α) and to up-regulate production of anti-catabolic factors (tissue inhibitors of metalloproteinase-1 and metalloproteinase-2). HA also enhanced expression of IL-10, an anti-inflammatory cytokine, in FLS. Our results indicated that HA can promote the expression of both antiinflammatory and structure-protective factors in FLS of patients with tibia plateau fracture.

Abstract
Hyaluronan (HA) of high molecular weight is used in the treatment of osteoarthritis and rheumatoid arthritis by intra-articular injection. While HA has been shown to suppress nuclear factor (NF)-κB activation by proinflammatory cytokines and lipopolysaccharide (LPS), intracellular upstream events that cause NF-κB down-regulation in response to HA remain unclear. Thus, this study was performed to investigate the involvement of phosphoinositide-3-OH kinase (PI3K)/Akt in the inhibition of the LPS-activated NF-κB pathway by HA in U937 macrophages. In adherent U937 macrophage cultures, pretreatment with HA of 2700 kDa (1 mg/ml, 1 h) significantly inhibited interleukin-6 (IL-6) production by LPS (200 ng/ml, 24 h)-stimulated U937 cells. LPS (200 ng/ml) activated Akt and NF-κB, whereas HA (1 mg/ml) down-regulated LPS-stimulated phosphorylation of Akt and NF-κB. Inhibition studies using LY294002 (20 µM) revealed the requirement of the PI3K/Akt pathway for LPS-stimulated IL-6 production and NF-κB activation. Pretreatment with anti-intercellular adhesion molecule-1 (ICAM-1) antibody (20 µg/ml) reversed the inhibitory effects of HA on LPS-induced production of IL-6 and activation of Akt and NF-κB. Herein, we provided the first evidence that HA suppresses the LPS-activated PI3K/Akt pathway, leading to down-regulation of NF-κB with diminished IL-6 production through interaction with ICAM-1.

Abstract
Osteoarthritis (OA), also called degenerative joint disease, is the most frequently occurring chronic musculoskeletal disease, particularly affecting the aging population. The use of viscosupplementation, i.e. intra-articular (IA) hyaluronic acid (HA) drug therapy, to treat OA, is growing worldwide, due to important results obtained from several clinical trials, which reported IA HA-related improvements in functional activity and pain management. This review is an update of the IA use of this compound in the treatment of OA, with clinical evidence from the last few years being discussed and used to delineate new trends for the future.

Abstract
Prostaglandin E2 (PGE2) is one of pro-inflammatory mediators. PGE2 maintains the homeostasis of many organs including articular cartilage, and a previous report showed that continuous inhibition of PGE2 accelerates the progression of osteoarthritis (OA). While PGE2 inhibits matrix metalloprotease (MMP) expression in several types of cells, little is known on direct effects of PGE2 on MMP expression in articular chondrocytes. The objective of this study was to investigate direct effects of PGE2 on IL-1beta-induced MMP-1 and MMP-13 expression and the intracellular signaling in articular chondrocytes. PGE2 showed inhibitory effects on IL-1beta-induced MMP-1 and MMP-13 expression demonstrated by immunoblotting both in OA and normal chondrocytes, which was further confirmed by enzyme-linked immunosorbent assay and immunohistochemistry of explant cultures of articular cartilages. An EP4 agonist, ONO-AE1-329, mimicked the inhibitory effect of PGE2, while an EP4 antagonist, ONO-AE3-208, blocked the effects. PGE2 suppressed the phosphorylation of JNK and ERK MAP kinases, but only knockdown of JNK by specific siRNA mimicked the effect of PGE2. PGE2 further inhibited the phosphorylation of MKK4 without suppression of MKK7 phosphorylation, and of c-JUN to decrease expression levels of MMP-1 and MMP-13. These results demonstrate that PGE2 inhibits IL-1beta-induced MMP-1 and MMP-13 productions via EP4 by suppressing MKK4-JNK MAP kinase-c-JUN pathway.

Abstract
This study was aimed to examine the inhibitory mechanism of high molecular weight hyaluronan (HA) on nitric oxide (NO) production by NH2-terminal heparin-binding fibronectin fragment (FN-f) in rheumatoid arthritis (RA) chondrocytes. When the RA cartilage explants or the isolated RA chondrocytes in monolayer were incubated with FN-f, the fragment stimulated NO production with induction of inducible nitric oxide synthase (iNOS) and activation of p38 mitogen-activated protein kinase. Pretreatment with 2,700 kDa HA resulted in significant suppression of FN-f-stimulated NO production in RA cartilage as well as in chondrocyte monolayer cultures in association with iNOS down-regulation. Inhibition studies with p38 inhibitor indicated the requirement of p38 for FN-f-induced NO production. HA suppressed p38 activation by the FN-f, leading to a decrease in NO production. Immunofluorescence cytochemistry revealed HA association with intercellular adhesion molecule-1 (ICAM-1) and CD44. While the individual antibody to ICAM-1 or CD44 partially reversed HA effect on the FN-f action, both antibodies in combination completely blocked the HA effect. The present study clearly demonstrated that the high molecular weight of HA suppressed the FN-f-activated p38 via ICAM-1 and the CD44 in RA chondrocytes. HA could down-regulate the catabolic action of FN-f in RA joints through the mechanism demonstrated in this study.

Abstract
It is important to develop a suitable three-dimensional scaffold for the regeneration therapy of dental pulp. In the present study, the effects of hyaluronic acid (HA) sponge on responses of the odontoblastic cell line (KN-3 cells) in vitro, as well as responses of amputated dental pulp of rat molar in vivo, were examined. In vitro, KN-3 cells adhered to the stable structure of HA sponge and that of collagen sponge. In vivo, dental pulp proliferation and vessel invasion were observed in both sponges implanted at dentin defect area above amputated dental pulp, and the cell-rich reorganizing tissue was observed in the dentin defect when HA sponge was implanted as compared with collagen sponge. Expression levels of IL-6 and TNF-alpha in KN-3 cells seeded in HA sponge were nearly the same with those in the cells seeded in collagen sponge, while the numbers (0.67 x 10(3) at 1 week and 0.7 x 10(3) at 3 weeks) of granulated leukocytes that invaded into HA sponge from amputated dental pulp was significantly lower than those (1.22 x 10(3) at 1 week and 1.1 x 10(3) at 3 weeks) of collagen sponge (p < 0.01 at 1 week and p < 0.05 at 3 weeks). These results suggest that HA sponge has an appropriate structure, biocompatibility, and biodegradation for use as a scaffold for dental pulp regeneration.

Abstract
BACKGROUND Preventing arthritic change in a joint with an intra-articular fracture remains a challenge, especially in weight-bearing joints. Hyaluronan (HA) has been proven to be effective in relieving joint pain and improving function in chronic osteoarthritis. However, controversy still exists about its potential use in a joint with an intra-articular fracture and about whether this effect is dependent on molecular weight. We analyzed and compared the effects of two different molecular weight HAs on six osteoarthritis-related proteins expressed in fibroblast-like synoviocytes from 12 patients with tibial plateau fracture. METHODS The interleukin (IL)-1beta-stimulated or IL-1beta-unstimulated fibroblast-like synoviocytes were cultivated with or without treatment by two different molecular weight HAs. The production of these proteins was quantified by using commercially available sandwich enzyme-linked immunosorbent assay. RESULTS The results revealed that HA with a high molecular weight is more effective in downregulating proinflammatory cytokines such as interleukin-1beta and tumor necrosis factor-alpha. Conversely, HA with a low molecular weight has greater efficacy in upregulating anticatabolic enzymes, such as tissue inhibitor of metalloproteinase-1 and tissue inhibitor of metalloproteinase-2, and in suppressing the catabolic enzyme, matrix metalloproteinase-3, which are thought to be more chondroprotective. CONCLUSIONS In a knee joint with an intra-articular fracture of the tibial plateau, we posit that high molecular weight HA may have a better anti-inflammatory effect, whereas low molecular weight HA has superior efficacy for chondroprotection.

Abstract
Hyaluronic acid (HA) has been widely used for viscosupplementation of diseased or aged articular joints. However, recent investigations have revealed the active anti-inflammatory or chondroprotective effect of HA, suggesting its potential role in attenuation of joint damage. In particular, interactions between HA and other inflammatory mediators are attracting interest. This review summarizes several aspects of recent investigations of the anti-inflammatory effects of HA in arthritis.

Abstract
Although a notable amount of CCL20 is detectable in the synovial fluid of human rheumatoid arthritis (RA), its role in the pathogenesis of RA remains to be determined. IL-1beta vigorously induced the production of CCL20 from FLSs of human RA and the production of CCL20 induced by TNF-alpha was partially attributed to a trace amount of IL-1beta induced by TNF-alpha. Although IL-6 failed to induce CCL20, TNF-alpha-induced IL-6 enhanced the production of CCL20 in an autocrine/paracrine manner. To determine the role of CCL20 and its sole receptor CCR6 in the recruitment of mononuclear cells (MNCs) into the inflamed joint of RA, conditioned medium of IL-1beta-stimulated FLSs was used in migration assays. The conditioned medium significantly recruited CCR6(+) MNCs in a CCL20-dependent manner. The production of CCL20 induced by TNF-alpha and IL-1beta was modified by helper-T-cell-derived cytokines. Interestingly, CCL20 enhanced the production of IL-6 coordinately with the stimulation of IL-17 but not with that of IFN-gamma. These findings imply FLSs stimulated by proinflammatory cytokines recruit CCR6(+) MNCs including IL-17-producing-helper T cells into the inflamed joint, leading to the enhancement of the production of CCL20, which chemokine and IL-17 coordinately induce proinflammatory cytokines.

Abstract
Mechanical stretch plays a crucial role in articular joints. In rheumatoid arthritis (RA), it is well known that fibroblast-like synoviocytes (FLS) produce matrix metalloproteinases (MMPs), resulting in local invasion into and degradation of bone and cartilage. We sought to examine whether mechanical stretch regulates the expression and underlying signal pathways of MMP secretion (MMP-1, -3, -13) in RA-FLS. FLS were grown on elastic silicone membrane in an equibiaxial strain apparatus and were exposed to 6% mechanical stretch (equivalent to gentle stretch exercise) for 15 min and 75 min, respectively. Semiquantitative PCR and real-time PCR were used to measure and analyze gene expression. Protein levels were determined by Western blotting. The results showed that 15 min of mechanical stretch inhibited MMP-1 and MMP-13 mRNA and protein level. However, the degree of inhibition by 75 min of stretch in expression of MMP-1 and MMP-13 was lower compared with 15 min stretch groups. The mRNA expression of ERK-1, ets-1 and citied-2 were increased by 6% mechanical stretch under both time points, however c-jun and c-fos mRNA level were affected differently after 15 min and 75 min mechanical stretch compared to control group. There were no significant changes on MMP-3 and ets-2 mRNA level under both 6% mechanical stretch time points. In the presence of pro-inflammatory cytokines (IL-1beta and TNF-alpha), the stretch also reduced the mRNA expression of MMP-1 and MMP-13. In short, our results showed that gentle mechanical strain affects MMP-1 and MMP-13 expression, potentially through the ERK-1-ets-1-cited-2-c-jun signaling pathway.

BACKGROUND AND PURPOSE Among the agents employed to manage osteoarthritis, chondroitin sulphate (CS) is a natural glycosaminoglycan with an anti-inflammatory effect on joint cells. CS might also influence the inflammatory component of atherosclerosis. Our aim was to examine the effect of CS administration on vascular injury and on markers of systemic inflammation in a rabbit model of atherosclerosis aggravated by systemic inflammation provoked by chronic antigen-induced arthritis. EXPERIMENTAL APPROACH Atherosclerosis was induced in rabbits by maintaining them on a hyperlipidaemic diet after producing an endothelial lesion in the femoral arteries. Simultaneously, chronic arthritis was induced in these animals by repeated intraarticular injections of ovalbumin in previously immunized rabbits. A group of these rabbits were treated prophylactically with CS (100 mg kg(-1)day(-1)) and when the animals were killed, serum and peripheral blood mononuclear cells (PBMC) were isolated. Furthermore, femoral arteries and thoracic aorta were used for gene expression studies and histological examination. KEY RESULTS CS administration reduced the concentration of the proinflammatory molecules C-reactive protein and IL-6 in serum. Likewise, CS inhibited the expression of CCL2/monocyte chemoattractant protein (MCP)-1 and cyclooxygenase (COX)-2 in PBMC, and reduced the nuclear translocation of nuclear factor-kappaB. In the femoral lesion, CS also diminished the expression of CCL2 and COX-2, as well as the ratio of the intima/media thickness. Moreover, CS decreased the percentage of rabbits with atherosclerosis and chronic arthritis that developed vascular lesions in the aorta. CONCLUSIONS AND IMPLICATIONS These findings suggest that CS treatment may to some extent impede the progression of atherosclerosis.
