Changes in Tibial Bone and Cartilage Structure in a Mouse Surgical Model of Osteoarthritis
Background/Purpose: The destabilisation of the medial meniscus (DMM) mouse osteoarthritis (OA) model is commonly used to study OA joint degeneration. In DMM-OA, the knee is…Abstract Number: 36 • 2012 ACR/ARHP Annual Meeting
Role of FK506 Binding Protein 5 in Osteoclast Differentiation
Background/Purpose: RA is a chronic, systemic inflammatory disease characterized by the destruction of bone in the joints. Moreover, it is well appreciated that systemic osteoporosis…Abstract Number: 37 • 2012 ACR/ARHP Annual Meeting
Development of a Mouse Model of Natural Osteoarthritis of Knee by Induction of obesity and Bipedal Walking
Background/Purpose: Animal models of osteoarthritis(OA) are used extensively in research of its pathogenesis and in search of disease modifying anti-OA drugs. However, whether current animal models…Abstract Number: 38 • 2012 ACR/ARHP Annual Meeting
Bone Marrow Lesions On Magnetic Resonance Imaging Are Not Associated with Regions of Hypermetabolism in an Animal Model of Osteoarthritis
Background/Purpose: The underlying histopathological basis for bone marrow lesions (BML) on magnetic resonance imaging (MRI) in osteoarthritis (OA) is unclear, but may be associated with…Abstract Number: 39 • 2012 ACR/ARHP Annual Meeting
SDF-1 Induces Osteoclastogenesis in Rheumatoid Arthritis by Upregulating of RANKL Expression in Synovial Fibroblasts and CD4+ T Cells
Background/Purpose: Stromal cell-derived factor (SDF)-1 is involved in bone destructive process in rheumatoid arthritis (RA) and bony metastasis in malignancy, through inducing angiogenesis, producing matrix-degrading…Abstract Number: 40 • 2012 ACR/ARHP Annual Meeting
Syndecan-4 Regulates Activation of WNT Signaling in Chondrocytes
Background/Purpose: Blockade of syndecan-4 (Sdc4) signaling protects mice from cartilage degradation in experimentally induced osteoarthritis (OA). Cartilage damage results in changes of chondrocyte phenotype induced…Abstract Number: 41 • 2012 ACR/ARHP Annual Meeting
Long-Distance Physical Connections Between Chondrocytes; Cell-to-Cell Communication within Articular Cartilage
Background/Purpose: It is believed that chondrocytes in cartilage do not connect each other, as they are isolated inside their lacunae separated from each other by…Abstract Number: 42 • 2012 ACR/ARHP Annual Meeting
Role of Stromal Cell-Derived Factor-1 Alpha Through Smad and MAPK Pathway On Endochondral Ossification
Background/Purpose: The main cellular events of articular chondrocytes during osteoarthritis are a loss of the traits as permanent cartilage, and a transition to hypertrophic chondrocytes…Abstract Number: 43 • 2012 ACR/ARHP Annual Meeting
Serum Amyloid A Level in Knee Osteoarthritis: Systemic and/or Local Production and Pro-Inflammatory Properties On Human Chondrocytes and Fibroblast-Like Synoviocytes
Background/Purpose: Knee osteoarthritis (OA) is a disease frequently seen in obese patients, but the relationship might be more linked to fat than to weight. A-SAA…Abstract Number: 44 • 2012 ACR/ARHP Annual Meeting
Inhibition of WNT Signaling Pathway by Sclerostin Maintains Cartilage Homeostasis
Background/Purpose: Cartilage homeostasis is regulated by several mechanisms that influence the anabolic and catabolic tissue balance. Among them, the local activation of Wnt signaling pathway…Abstract Number: 45 • 2012 ACR/ARHP Annual Meeting
The Effects of Apremilast On Osteoclasts, Osteoblasts, and Osteocytes
Background/Purpose: Apremilast (APR), a small molecule specific inhibitor of phosphodiesterase 4, works intracellularly to modulate pro- and anti-inflammatory mediator production in both immune and non-immune…Abstract Number: 6 • 2012 ACR/ARHP Annual Meeting
The Effect of Hydrogen Sulfide Donors On Inflammatory Mediators in Human Articular Osteoarthritic Chondrocytes
Background/Purpose: Hydrogen sulfide (H2S) has recently been proposed as an endogenous mediator of inflammation in several pathology models. The aim of this work was to…Abstract Number: 7 • 2012 ACR/ARHP Annual Meeting
Lamin A Deregulation in Human Mesenchymal Stem Cells Promotes an Impairment in Their Chondrogenic Potential and Imbalance in Their Response to Oxidative Stress
Background/Purpose: Previous work by our group and others indicated that an accumulation of lamin A (LMNA) was associated with the osteoarthritis (OA) chondrocyte phenotype. Mutations…Abstract Number: 8 • 2012 ACR/ARHP Annual Meeting
Supercharged Sox9 Protein Induces Chondrogenic Differentiation of Bone Marrow-Derived Mesenchymal Stem Cells
Background/Purpose: Osteoarthritis (OA) is characterized by progressive breakdown of articular cartilage. Regeneration of cartilage has been an attractive approach to OA therapy. Sox9 is a…Abstract Number: 9 • 2012 ACR/ARHP Annual Meeting
Function of the Chondrocyte PI-3 Kinase Akt Signaling Pathway Is Stimulus Dependent
Background/Purpose: Previous studies have shown that activation of the chondrocyte PI-3K-Akt signaling pathway by IGF-1 promotes chondrocyte survival and matrix synthesis. However, other studies have…
