Effect of the interleukin-1β on gelatinolytic activity and cell morphology of human osteoarthritic chondrocytes in culture
We report the effect of recombinant human interleukin-1β (IL-1β) on cell morphology and on the pattern of matrix metalloproteinase (MMP) gelatinolytic activity expressed by quiescent and growing human osteoarthritic chondrocytes. After treatment with IL1β, gelatin zymography revealed a significant increase of 64-62 kDa MMP-2 active forms suggesting an overexpression of its activator membrane ty...
متن کاملProtective Effects of Interleukin-4 on Tissue Destruction and Morphological Changes of Bovine Nasal Chondrocytes in vitro
Background: Previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. In the current study, effects of IL-4 against morphological changes and tissue degradation induced by IL-1α on bovine nasal cartilage (BNC) explants were investigated. Methods: Fresh BNC samples were prepared from a slaughterhouse under sterile conditions. BNC explants culture was...
متن کاملEvaluation of CD98 Expression in Normal and Osteoarthritic Human Articular Chondrocytes
Background: Recent studies have provided evidence that integrins play roles in recognition of mechanical stimuli and its translation into a cellular response. Integrin signaling may be regulated by a number of mechanisms including accessory proteins such as CD98 (4F2 antigen). Objectives: To determine CD98 expression by human articular chondrocytes and its involvement in human articular mechano...
متن کامل4-Hydroxynonenal induces apoptosis in human osteoarthritic chondrocytes: the protective role of glutathione-S-transferase
INTRODUCTION 4-Hydroxynonenal (HNE) is one of the most abundant and reactive aldehydes of lipid peroxidation products and exerts various effects on intracellular and extracellular signalling cascades. We have previously shown that HNE at low concentrations could be considered as an important mediator of catabolic and inflammatory processes in osteoarthritis (OA). In the present study, we focuse...
متن کاملMicroRNA-125b regulates the expression of aggrecanase-1 (ADAMTS-4) in human osteoarthritic chondrocytes
INTRODUCTION Increased expression of aggrecanase-1 (ADAMTS-4) has emerged as an important factor in osteoarthritis (OA) and other joint diseases. This study aimed to determine whether the expression of ADAMTS-4 in human chondrocytes is regulated by miRNA. METHODS MiRNA targets were identified using bioinformatics. Chondrocytes were isolated from knee cartilage and treated with interleukin-1 b...
