In the present study, the levels of synovial fluid biomarkers of patients with knee osteoarthritis (OA) and those with meniscus injury (MI) were compared to associate the levels of synovial fluid biomarkers with the degree of OA and MI. Synovial fluid samples were obtained from 51 cases with OA and 40 patients with MI. Severity of OA and MI were evaluated using the Kellgren-Lawrence (K-L) classification and Magnetic Resonance Imaging Osteoarthritis Knee Score, respectively. A comparative analysis of the levels of matrix metalloproteinase-13 (MMP-13), vascular endothelial growth factor (VEGF), interleukin (IL)-10, IL-8, IL-6, IL-1, tumor necrosis factor-α (TNF-α), as well as collagenase 2 in synovial fluid was made between patients with OA and MI...

INTRODUCTION: In this article, we explored the hypothesis that the long noncoding RNA, Nespas, promotes osteoarthritis (OA) by supporting abnormal lipid metabolism in human chondrocytes. MATERIALS AND METHODS: Human articular chondrocytes from osteoarthritis patients were used and expression level of Nespas were determined by real-time polymerase chain reaction. Introduction of Nespas and Nespas-associated genes/miRNAs were performed by using a lentiviral system...

BACKGROUND: Osteopontin (OPN) is an immunoregulatory protein which production increases in both rheumatoid arthritis (RA) and osteoarthritis (OA). Phosphorylated osteopontin (Phospho-OPN) is known to increase macrophage and osteoclast activation, this process is controlled by extracellular tartrate-resistant acid phosphatase (TRAcP), also a biomarker for RA. Here, we evaluated the phosphorylation status of OPN in RA and OA synovia, as well as its correlation with TRAcP isoforms. METHODS: Synovial tissue and fluid were obtained from 24 RA (14 seropositive and 10 seronegative) and 24 OA patients...

Biomarkers of osteoarthritis (OA) that can accurately diagnose the disease at the earliest stage would significantly support efforts to develop treatments for prevention and early intervention. We have sought to determine the time course of alterations in peripheral blood gene expression profile associated with the development of OA. Blood samples were collected from a tail vein of individual rats with monosodium iodoacetate- (MIA-) induced OA (2, 14, 21, and 28 days after the treatment). We used whole-genome microarrays to reveal OA-related transcriptional alterations of 72 transcripts...

Although the potential effect of aberrant expression of catabolic and anabolic genes on the development of osteoarthritis (OA) is well-documented, the regulatory mechanism for the expression of these genes in articular chondrocytes remains to be elucidated. The recent advances in epigenetic studies have identified microRNA (miRNA) as one of the epigenetic mechanisms for the regulation of gene expression. This mini review highlights the role of miRNA in the regulation of gene expression in articular chondrocytes and its significance in the pathogenesis of OA, with a discussion on the potential of miRNA as a new biomarker and therapeutic target for OA...

Valgus unloader braces are a conservative treatment option for medial compartment knee osteoarthritis that aim to unload the damaged medial compartment through application of an external abduction moment. Patient response to bracing is highly variable, however. While some experience improvements in pain, function, and joint loading, others receive little to no benefit. The objective of this work was to analyze clinical measures and biomechanical characteristics of unbraced walking to identify variables that are associated with the mechanical effectiveness of valgus unloader bracing...

BACKGROUND: Associations between Transforming Growth Factor beta-1 (TGF-β1), Platelet-derived growth factor BB (PDGF-BB) and C-terminal telopeptide of type I collagen (CTX-1) with pathogenesis of osteoarthritis (OA) have already been established. Therefore, TGF-β1, PDGF-BB and CTX-1 could be used as the potential biomarkers for the diagnosis of this disease. METHODS: 160 knee OA cases and 80 healthy controls were chosen. Serum concentrations of TGF-β1, PDGF-BB and CTX-1 were tested twice on the same samples using Enzyme-Linked Immunosorbent Assay...

Osteoarthritis is a common disease and is frequently encountered in the older population; the incidence rises sharply with age. It is estimated that more than 360 million people suffer from OA. However, the pathogenesis of osteoarthritis remains unclear, and we cannot effectively prevent the progression of OA. The aim of this review was to explore the molecular markers and signaling pathways that induce chondrocyte apoptosis in OA. We searched, using the key words osteoarthritis, chondrocyte apoptosis, autophagy, endoplasmic reticulum stress, molecular targets, and biomarkers, in PubMed, Web of Science, and Google Scholar from 1994 to 2017...

BACKGROUND: There is an obvious need to identify biomarkers that could predict patient response to an osteoarthritis (OA) treatment. This post hoc study explored in a 2-year randomized controlled trial in patients with knee OA, the likelihood of some serum biomarkers to be associated with a better response to chondroitin sulfate in reducing cartilage volume loss. METHODS: Eight biomarkers were studied: hyaluronic acid (HA), C reactive protein (CRP), adipsin, leptin, N-terminal propeptide of collagen IIα (PIIANP), C-terminal crosslinked telopeptide of type I collagen (CTX-1), matrix metalloproteinase-1 (MMP-1), and MMP-3...

Circular RNAs (circRNAs) are a class of long, non-coding RNAs molecules that shape a covalently closed continuous loop which have no 5'-3' polarity and contain no polyA tail. CircRNAs also possess relatively jarless framework and are highly tissue-specific expressed in the eukaryotic transcriptome. Emerging evidences have discovered that thousands of endogenous circRNAs are present in mammalian cells and they mediate gene expression at the transcriptional or post-transcriptional level by binding to microRNAs or other molecules and then inhibit their function...

BACKGROUND: Osteoarthritis (OA) is the most common chronic joint disease usually diagnosed at relatively advanced stages when there is irreparable damage to the joint(s). Recently, we have identified two novel biomarkers C3f and V65 which appear to be OA-specific and therefore potential markers of early disease. We report the development of immunoassays for quantitative measure of these two novel biomarkers. METHOD: Monoclonal and polyclonal antibodies were generated by immunising mouse and rabbits respectively with peptide-carrier conjugates of C3f and V65...

Knee osteoarthritis (OA) progression can be monitored by measuring changes in the subchondral bone structure such as area and shape from MR images as an imaging biomarker. However, measurements of these minute changes are highly dependent on the accurate segmentation of bone tissue from MR images and it is challenging task due to the complex tissue structure and inadequate image contrast/brightness. In this paper, a fully automated method for segmenting subchondral bone from knee MR images is proposed. Here, the contrast of knee MR images is enhanced using a gray-level S-curve transformation followed by automatic seed point detection using a three-dimensional multi-edge overlapping technique...

Osteoarthritis (OA) of temporomandibular joints (TMJ) occurs in about 40% of the patients who present TMJ disorders. Despite its prevalence, OA diagnosis and treatment remain controversial since there are no clear symptoms of the disease, especially in early stages. Quantitative tools based on 3D imaging of the TMJ condyle have the potential to help characterize TMJ OA changes. The goals of the tools proposed in this study are to ultimately develop robust imaging markers for diagnosis and assessment of treatment efficacy...
