Influence of age on osteoarthritis progression after anterior cruciate ligament transection in rats.

2013

Abstract The anterior cruciate ligament transection (ACLT) model of osteoarthritis (OA) in young rats is widely used to study the pathogenesis of OA and possible treatment approaches. As aging is a key factor in the progression of this condition, it is hypothesized that animals may vary in their responses to ACLT according to their age. The histopathological features of young (2 month-old) and middle-aged (12 month-old) rats in the presence or absence of ACLT were compared. The results indicated that moderate degradative changes can be detected in the knee joints of sham-operated middle-aged rats compared with young animals. After ACLT, cartilage degradation was significantly higher in midd…

THU0413 New Formulation with Potential for the Prevention and Treatment of Osteoporosis and Osteoarthritis

2013

Background Osteoarthritis (OA) is a multidimensional disease that affects all anatomical joint structures, particularly cartilage, synovium and subchondral bone. In turn, osteoporosis (OP) is a skeletal disorder characterized by a compromised bone strength which substantially increases the risk of fracture. Both are common disorders which affect quality of life in elderly. Despite this, there is not any drug at the moment for the simultaneous prevention and treatment of osteoporosis and osteoarthritis. Objectives The aim of this study was to investigate the effect of a new formulation in a combined rat model of OP and OA. The formulation (BIS076) contains Vitamin D3, Hydroxyapatite as a sou…

Chondroprotective effects of the combination chondroitin sulfate-glucosamine in a model of osteoarthritis induced by anterior cruciate ligament trans…

2016

[EN] Context: The efficacy of the combination chondroitin sulfate-glucosamine (CS-GlcN) in the treatment of knee osteoarthritis (OA) has been suggested in recent clinical studies. In vitro reports have also suggested anti-inflammatory and anti-resorptive effects of this combination. Objective: The aim of this study was to characterize the effects of CS-GlcN on joint degradation in vivo including the assessment of inflammation and bone metabolism in a model of OA. Materials and methods: We have used the OA model induced by anterior cruciate ligament transection (ACLT) in ovariectomised rats. CS-GlcN was administered daily (oral gavage) from week 0 until week 12 after ovariectomy at the dose …

Effects of BIS076 in a model of osteoarthritis induced by anterior cruciate ligament transection in ovariectomised rats

2015

Background Osteoarthritis (OA) is the most frequent articular disease and a leading cause of disability. There is a need for effective treatments able to slow the progression of disease. Some of the available treatments are dietary supplements providing natural components. Recent studies have shown that estrogen deficiency contributes to the pathophysiological events of OA progression. Methods We have used the anterior cruciate ligament transection model of OA in ovariectomised rats to study the effects of BIS076, a new formulation of a natural porcine cartilage extract associated with hydroxyapatite (as a source of calcium) and vitamin D3. Cartilage degradation, proteoglycan depletion and …

Potential antipsoriatic effect of chondroitin sulfate through inhibition of NF-κB and STAT3 in human keratinocytes

2012

Abstract Chondroitin sulfate (CS) is a natural glycosaminoglycan, formed by the 1–3 linkage of d -glucuronic acid to N-acetylgalactosamine, present in the extracellular matrix. It is used as a slow acting disease modifying agent in the treatment of osteoarthritis, and part of its beneficial effects are due to its antiinflammatory properties that result from an inhibitory effect on NF-κB signaling pathway. This ability raises the hypothesis that CS might be effective in other chronic inflammatory processes such as psoriasis, in which a deregulation of NF-κB is a key feature. In addition, psoriasis is characterized by an upregulation of STAT3 signaling pathway that is related to the epidermal…
