Glucosamine (GlcN) is one of the dietary supplements used in the treatment of osteoarthritis. Endogenously, GlcN is synthesized from glucose through the hexosamine pathway. In addition to ameliorating arthritis, several biological functions of GlcN have been reported, including insulin resistance in skeletal muscle. However, the regulatory role of GlcN in skeletal muscle development is not clear. We therefore investigated the effect of GlcN on myoblast proliferation, differentiation, and myotube development and their underlying mechanisms in C2C12 cells. Myoblast proliferation was measured by MTT assay. The expressions of MyoD, myogenin (MyoG), and myosin heavy chain (MyHC) were identified as determinants of myoblast differentiation. Expressions of atrogin-1 and muscle RING-finger protein-1 (MuRF-1) were identified as markers of myotube atrophy. The results show that treatment with GlcN significantly reduced myoblast proliferation and phosphorylation of Stat3 and S6K. These findings suggest that GlcN can inhibit growth of myoblasts through inhibiting phosphorylation of Stat3 and S6K. In addition, GlcN significantly suppressed the expression of MyoD, MyoG, and MyHC, as well as myotube formation. Pretreatment of C2C12 myoblast cells with ER stress inhibitors significantly blocked GlcN-inhibited MyHC expression and myotube formation. It can be concluded that GlcN suppressed myogenic differentiation via a pathway that involved ER stress. Moreover, GlcN decreased myotube diameter and expression of MyHC, as well as increased MuRF-1 in C2C12 myotubes. Meanwhile, GlcN also reduced the expressions of phosphorylated Akt and mTOR were stimulated after GlcN treatment in C2C12 myotubes. Thus, GlcN induced skeletal muscle atrophy by inhibiting the protein synthesis pathway. Chronic GlcN infusion also caused skeletal muscle atrophy in mice. In conclusion, GlcN regulated important stages of skeletal muscle development through different signaling pathways.

Enhancing GFPT1 expression with glutamine protects chondrocytes in osteoarthritis

Author: Li, Xinyu ; Huang, Zeyu ; Guo, Weihua ; Zhang, Zhao

OBJECTIVEOsteoarthritis (OA) is the leading joint disease without currently available disease-modified drugs. The current study aimed to identify potential drug targets that could decelerate the progression of OA.METHODSWe employed Mendelian Randomization (MR) and colocalization analysis to identify therapeutic targets linked to 12 OA traits within 2645 targets. Bulk and single-cell RNA-seq analyses of cartilage samples were conducted to pinpoint GFPT1 and determine the specific cell types in which GFPT1 is expressed. Overexpression and knockdown experiments further explored the expression and potential OA-associated functions of GFPT1.RESULTSGFPT1 has been identified as a cross-OA therapeutic candidate gene by MR analysis. We observed a significant reduction in GFPT1 expression in OA cartilage compared to normal cartilage from public transcriptomic data of both humans and mice. In vitro experiments confirmed these findings at both mRNA and protein levels in OA chondrocytes. IL-1β stimulation leads to downregulation of GFPT1. We confirmed that supplementary glutamine can reverse the suppression of GFPT1 more effectively than glucosamine in the OA in vitro model. GFPT1 upregulation with glutamine, in turn, further increases the expression of COL2A1 and decreases the expression of MMP13.CONCLUSIONSOur findings demonstrate that GFPT1 is downregulated in OA, and overexpressing GFPT1 can restore the anabolic metabolism of cartilage. Compared to glucosamine, enhancing GFPT1 expression with glutamine to influence the hexosamine biosynthetic pathway may offer a more effective therapeutic strategy for OA.

Can treatment with chondroitin and glucosamine sulphate prevent changes in the articular disc caused by temporomandibular joint osteoarthritis?

Article

Author: Malaguez, Giulia Giacomini ; Ponzoni, Deise ; Artuzi, Felipe Ernesto ; Quevedo, Alexandre Silva ; Puricelli, Edela

AbstractBackgroundChondroitin and glucosamine sulphates (CGS) are considered structure‐modifying drugs and have been studied in the prevention, delay or reversal of structural morphological changes in joints caused by osteoarthritis.ObjectiveThe aim of the present study was to investigate the action of CGS on the progression of chemically induced osteoarthritis in the temporomandibular joint (TMJ) of rabbits by evaluating the serum levels of tumour necrosis factor (TNF‐α) and collagen in the articular discs.Materials and MethodsA sample of 36 male rabbits was divided into three groups: control (CG), osteoarthritis (OG) and treatment (TG). The disease was induced by intra‐articular injection of sodium monoiodoacetate (10 mg/mL) in the OG and TG groups bilaterally. After 10 days, the TG animals received subcutaneous injection of chondroitin sulphates and glucosamine (7.5 mg/kg) and the OG and CG received saline solution (50 μL). Euthanasia times were subdivided into 40 and 100 days. Collagen quantification was performed by biochemical and histological analysis and for the quantification of serum levels of TNF‐α, an enzyme immunoassay was used.ResultsThe TG showed an increase in the collagen area of the articular disc when compared to the CG and the OG. The increase collagen concentration in the discs did not show a statistically significant difference between the groups. Post‐treatment TNF‐α levels were significantly lower in TG compared to OG.ConclusionsThe results indicate that CGS treatment delayed the degeneration of the collagen in the TMJ articular disc and reduced serum TNF‐α levels, indicating a preventive effect on OA progression.
