The aim of this study was to determine the anti-osteoarthritic effects of LI73014F2, which consists of Terminalia chebula fruit, Curcuma longa rhizome, and Boswellia serrata gum resin in a 2:1:2 ratio, in the monosodium iodoacetate (MIA)-induced osteoarthritis (OA) rat model. LI73014F2 was orally administered once per day for three weeks. Weight-bearing distribution and arthritis index (AI) were measured once per week to confirm the OA symptoms. Synovial membrane, proteoglycan layer, and cartilage damage were investigated by histological examination, while synovial fluid interleukin-1β level was analyzed using a commercial kit. Levels of pro-inflammatory mediators/cytokines and matrix metalloproteinases (MMPs) in the cartilage tissues were investigated to confirm the anti-osteoarthritic effects of LI73014F2. LI73014F2 significantly inhibited the MIA-induced increase in OA symptoms, synovial fluid cytokine, cartilage damage, and expression levels of pro-inflammatory mediators/cytokines and MMPs in the articular cartilage. These results suggest that LI73014F2 exerts anti-osteoarthritic effects by regulating inflammatory cytokines and MMPs in MIA-induced OA rats.

Therapeutic effects of GCSB-5 on osteoarthritis were measured by the amount of glycosaminoglycan in rabbit articular cartilage explantsin vitro, in experimental osteoarthritis induced by intra-articular injection of monoiodoacetate in ratsin vivo. GCSB-5 was orally administered for 28 days.In vitro, GCSB-5 inhibited proteoglycan degradation. GCSB-5 significantly suppressed the histological changes in monoiodoacetate-induced osteoarthritis. Matrix metalloproteinase (MMP) activity, as well as, the levels of serum tumor necrosis factor-α, cyclooxygenase-2, inducible nitric oxide synthase protein, and mRNA expressions were attenuated by GCSB-5, whereas the level of interleukin-10 was potentiated. By GCSB-5, the level of nuclear factor-κB p65 protein expression was significantly attenuated but, on the other hand, the level of inhibitor of κB-α protein expression was increased. These results indicate that GCSB-5 is a potential therapeutic agent for the protection of articular cartilage against progression of osteoarthritis through inhibition of MMPs activity, inflammatory mediators, and NF-κB activation.

The study aimed to investigate the preservative effects of genistein on articular cartilage in an experimental model of knee osteoarthritis in rats. Thirty male Wistar rats were assigned to three equal groups: the sham group (SG), osteoarthritis control group (OAG), and genistein-treated osteoarthritis group (GTG). Intra-articular injections of monosodium iodoacetate were used for osteoarthritis induction. After two weeks of rest for the induction of the inflammatory process, genistein (30 mg/kg/day) vs. saline gavage was administered for eight weeks. The expression of matrix metalloproteinase (MMP) 8 and 13, Sox5/Sox6, Indian hedgehog (IHH), and Col2 were evaluated in medial femoral condyle sections by immunohistochemical staining. The number of chondrocytes and cartilage thicknesses were also measured and compared among the groups. No significant change in cartilage thickness was observed in GTG compared with OAG (p=0.188). Chondrocyte count was significantly higher in the articular cartilage of GTG compared with OAG (p=0.006). Induction of OA significantly increased the expression of MMP-8, MMP-13, and IHH, but decreased Col2, Sox5, and Sox6 expression (p<0.001); these were partially prevented in the GTG. Our findings support the effectiveness of genistein treatment in the prevention of articular cartilage damage in the experimental model of knee osteoarthritis. The proposed mechanism of action is through the suppression of the MMP, IHH, Col2 pathways, besides the induction of Sox5 and Sox6 expression. Novelty: -Genistein prevent articular cartilage damage in the experimental model of knee osteoarthritis. -The osteoprotective effect is trough modulation of expression of MMP, Sox, IHH, and Col2 proteins.

Inflammatory Component

Osteoarthritis is a degenerative joint disease which primarily affects the articular cartilage and subchondral bones. Since there is an underlying localized inflammatory component in the pathogenesis of osteoarthritis, compounds like tocotrienol with anti-inflammatory properties may be able to retard its progression. This study aimed to determine the effects of oral tocotrienol supplementation on the articular cartilage and subchondral bone in a rat model of osteoarthritis induced by monosodium iodoacetate (MIA). Thirty male Sprague-Dawley rats (three-month-old) were randomized into five groups. Four groups were induced with osteoarthritis (single injection of MIA at week 0) and another served as the sham group. Three of the four groups with osteoarthritis were supplemented with annatto tocotrienol at 50, 100 and 150 mg/kg/day orally for five weeks. At week 5, all rats were sacrificed, and their tibial-femoral joints were harvested for analysis. The results indicated that the groups which received annatto tocotrienol at 100 and 150 mg/kg/day had lower histological scores and cartilage remodeling markers. Annatto tocotrienol at 150 mg/kg/day significantly lowered the osteocalcin levels and osteoclast surface of subchondral bone. In conclusion, annatto tocotrienol may potentially retard the progression of osteoarthritis. Future studies to confirm its mechanism of joint protection should be performed.

Abstract Background Osteoarthritis (OA) is a chronic disease that can cause disability. The prevalence of osteoarthritis has increased year by year, become a disease that mainly causes the elderly to suffer. With the increasing understanding of bone marrow mesenchymal stem cell (BMSC) in tissue repair, BMSCs shown good therapeutic effects in OA, it may be due to BMSCs exerted their capacities of differentiation, secretion and immunoregulatory in the joints. As previous describe, BMSCs culture supernatant is proved that rich in multiple cytokines. Therefore, how BMSCs injection therapy exerts its ability to exert therapeutic effects, and whether its therapeutic effect can be replaced by its culture supernatant has become the focus of this article. Methods In vitro, we designed a co-culture system to deepen understand this new stem cell therapy. Through two kinds of cells cultured alone, direct and indirect cell contact co-culture to observe changes in cell morphology, quantity and cytoplasmic glycoprotein of these two types of cells and changes of the level of growth factor in the culture supernatant to explore the interaction of these two types of cells; in vivo, we induced an OA model and Injected Saline solution, BMSCs and their culture supernatants respectively for treatment, then we compared the improvement results of OA by evaluating changes in the cartilage layer after different treatments. And determine the changes of some growth factors and inflammatory factors in synovial fluid to analyze the possible mechanisms of multiple treatments. Result In the co-culture system, it was found that the direct co-culture of BMSCs and OCs can enhance the proliferation ability of OCs, OCs can retain more cytoplasmic glycoprotein, and BMSCs did not occurred abnormal differentiation during the co-culture. In animal experiments, it was found that the ability of BMSCs injection treatment has obvious therapeutic effect on OA, and the effect is better than its supernatant injection treatment. BMSCs therapy reduced matrix loss in articular cartilage cells, and reduced type I collagen production and fibrosis on articular cartilage, effectively regulating EGF and TGF-β1change and inhibited intra-articular inflammation. Supernatant injection treatment will not significantly delay the progress of OA, and it cannot replace BMSCs for the treatment of OA. Conclusion BMSCs therapy is a potential new therapy for OA. The secretion and regulation ability of BMSCs plays an important role in the treatment process. BMSCs are activated by the intra-articular environment of OA, regulating growth factors such as EGF and TGFβ to promote articular cartilage regeneration, and reducing intra-articular inflammation by regulating inflammatory factors and delaying the progression of OA. These effects cannot be replaced by the culture supernatant which is rich in multiple factors, and its regulation function requires the presence of BMSCs. These results provide a relatively comprehensive understanding of BMSCs cell therapy in OA and provide a new explanation for the possible anti-inflammatory effects of BMSCs in the joint.
