OBJECTIVE
Pleiotrophin is a heparin-binding growth factor expressed in embryonic but not mature cartilage, suggesting a role in cartilage development. Elucidation of the molecular changes observed during the remodelling process in osteoarthritis is of paramount importance. This study aimed to
The influence of non-steroidal anti-inflammatory drugs (NSAIDs) and of disease activity on the serum alkaline phosphatase concentration was examined in patients with rheumatoid arthritis, osteoarthritis, and polymyalgia rheumatica. Concentrations of serum alkaline phosphatase were similar both in
BACKGROUND
Osteoarthritis (OA) is a degenerative joint disease with poorly understood etiology and pathobiology. Mitogen activated protein kinases (MAPKs) including ERK and p38 play important roles in the mediation of downstream pathways involved in cartilage degenerative processes. Dual specificity
A study has been carried out on the alkaline phosphatase activity in trabecular bone in the normal state, rheumatoid arthritis and osteoarthritis. Samples were taken from the subchondral bone of the medial tibial condyle in all cases. The reason for this study was to investigate whether changes in
OBJECTIVE
To characterise the role of phosphatase-1 and -2A (PP1/2A) in the modulation of apoptosis in human osteoarthritis (OA) chondrocytes.
METHODS
Human OA chondrocytes were isolated from cartilage obtained from the femoral heads of patients undergoing joint replacement surgery. Cell viability
OBJECTIVE
Determination of the serum levels of Receptor Activator of Nuclear Factor-Κb Ligand, bone-specific alkaline phosphatase, osteocalcin and osteoprotegerin in patients suffering from osteoarthritis of varying severity and healthy controls and correlation of these results with the patients'
Increasing evidence indicates the important role of inflammation in the pathogenesis and progression of osteoarthritis (OA). Dual specificity phosphatase 1 (DUSP1), a negative regulator of the mitogen‑activated protein kinase (MAPK) signaling pathway, has anti‑inflammatory properties. In the present
The influx of cells into the synovial intima in rheumatoid joints may include osteoclasts and their precursors. The distribution of osteoclast markers--namely, tartrate resistant acid phosphatase activity and the expression of vitronectin receptor (shown with monoclonal antibodies 13C2 and
The study was carried out concerning indices of electrolytic content and phosphatase activity of synovial fluid in patients with degenerate dystrophic affections of knee joints stage II and III. The detection of rate of occurrence of alterations of studied indices established that most often
The temporo-mandibular joint of aged mice develops osteoarthritic (OA) degenerative lesions. Adult chondrocytes have a low rate of cell replication, and cartilage repair potential is very limited. One of the major problems in OA is the low rate of matrix synthesis and the inability of the
We aimed to establish the characteristics of synovium-derived mesenchymal stem cells (MSCs) from the hip joints of patients with femoroacetabular impingement syndrome (FAIS) and osteoarthritis (OA), particularly their proliferation and differentiation potentials. We further The aim of this study was to compare the osteogenic potential and responsiveness to leptin of mesenchymal stem cells (MSCs) from bone marrow between postmenopausal women with osteoarthritis (OA) and osteoporosis (OP). MSCs of the proximal femur from OA and OP donors were cultured under control and
Although osteoarthritis is characterized by a progressive loss of the extracellular cartilage matrix, very little is known about the fate of articular chondrocytes during the progression of the disease. In this study we examined the expression of syndecan-3, a marker of early chondrocyte
Musculoskeletal conditions are a major burden on individuals, healthcare systems, and social care systems throughout the world, with indirect costs having a predominant economic impact. Aging is a major contributing factor to the development and progression of arthritic and musculoskeletal diseases.
