Impact of glycogen synthase kinase-3ß inhibition on rats' temporomandibular joint collagen-induced rheumatoid arthritis with correlation to miRNA-155/miRNA-24 expression.
    European review for medical and pharmacological sciences, 2023, Volume: 27, Issue:16

    The current study considered assessing the role of miRNA-155 and miRNA-24 in collagen-induced rheumatoid arthritis (RA) in rats' temporomandibular joint (TMJ). Their role in histological aggressiveness of the disease and therapy response to glycogen synthase kinase (GSK) inhibitor 4-benzyl-2-methyl-1,2,4-thiadiazolidine-3,5-dione (TDZD-8) will be studied.. Rats were randomly distributed to four groups (8 rats/group): group I negative control, group II collagen-induced rheumatoid arthritis (CIA), group III Control+TDZD-8 treated group, and group IV CIA+TDZD-8 treated group. Then were euthanized 42 days after the start of the experiment. H&E staining, Masson trichrome staining, and immunohistochemical antibodies against S100 were performed. qRT-PCR of miRNA-155 and miRNA-24 were done for frozen synovial tissues.. Histological analysis showed that the most affected structure in induced rheumatoid arthritis of TMJ is the articular disc, condylar head, and subchondral bone. Combined treatment with TDZD-8 improved histological status in the joint. Masson's trichrome (MTC) histochemical staining revealed disarrangement of collagen fibers and adherence between the articular disc and condylar cartilage. Meanwhile, the morphology and collagen composition of the disc and condyle in CIA+ TDZD-8 were similar to those of healthy tissues. Immunohistochemical analysis for S100A4 revealed increased immunoreactivity staining in the CIA group. The immunoreactivity was significantly decreased in CIA+ TDZD-8 treated group. TDZD-8 significantly decreased the levels of miRNA-155 and miRNA-24 in synovial tissue.. Our results reveal for the first-time correlation of miRNA-155 and miRNA-24 that might be implicated in the onset of TMJ RA. Consequently, the treatment of CIA with GSK inhibitor (TDZD-8) yields encouraging results. We predicted the TDZD-8 might protect against CIA by suppressing miRNA-155, miRNA-24, and S100A4 protein levels.

Inhibition of GSK-3β Alleviates Collagen II-Induced Rheumatoid Arthritis in Rats.
    Medical science monitor : international medical journal of experimental and clinical research, 2016, Mar-31, Volume: 22

    Glycogen synthase kinase-3β (GSK-3β) inhibitor is a serine/threonine kinase with an inhibitory role in glycogen synthesis, which is essential in inflammatory and immunological diseases. The purpose of our study was to determine if TDZD-8 can alleviate collagen II-induced rheumatoid arthritis in rats.. Twenty collagen II-induced rheumatoid arthritis rats were treated with selective GSK-3β inhibitor. The effects of GSK-3β inhibition on collagen II-induced rheumatoid arthritis in the rats were evaluated by paw edema, histological examination of arthritic synovium, radiographic examination of knee joint, and the level of inflammation mediators such as prostaglandin E2, 5-hydroxytryptamin, and histamine. The level of cytokines such as IL-6, IL-12, IL-10, and TNF-α, was examined by Elisa.. GSK-3β inhibitor significantly reduced the development of rheumatoid arthritis in rats. The levels of inflammation mediators such as prostaglandin E2, 5-hydroxytryptamin, and histamine were decreased in the TDZD-8 group. Serum levels of IL-6, IL-12, and TNF-α were significantly reduced in the TDZD-8 group compared with the RA group.. Treatment with GSK-3β inhibitor suppressed inflammatory response in RA rats. These findings suggest that the inhibition of GSK-3β can be an effective treatment for RA.

Glycogen synthase kinase-3beta inhibition attenuates the degree of arthritis caused by type II collagen in the mouse.
    Clinical immunology (Orlando, Fla.), 2006, Volume: 120, Issue:1

    Recently, glycogen synthase kinase-3 (GSK-3) has being identified as an ubiquitous serine-threonine protein kinase that participates in a multitude of cellular processes and plays an important role in the pathophysiology of a number of diseases. The aim of this study was to investigate the effects of GSK-3beta inhibition on the degree of arthritis caused by type II collagen (CII) in the mouse (collagen-induced arthritis; CIA). Mice developed erosive hind paw arthritis when immunized with CII in an emulsion in complete Freund's adjuvant (CFA). The incidence of CIA was 100% by day 28 in the CII-challenged mice and the severity of CIA progressed over a 35-day period with radiographic evaluation revealing focal resorption of bone. The histopathology of CIA included erosion of the cartilage at the joint margins. Treatment of mice with the GSK-3beta inhibitor TDZD-8 (1 mg/kg/day i.p.) starting at the onset of arthritis (day 25) ameliorated the clinical signs at days 26-35 and improved histological status in the joint and paw. Immunohistochemical analysis for nitrotyrosine, poly(ADP-ribose) (PAR), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) revealed a positive staining in inflamed joints from mice subjected to CIA. The degree of staining for nitrotyrosine, PAR, iNOS, and COX-2 was significantly reduced in CII-challenged mice treated with the GSK-3beta inhibitor. Plasma levels of tumor necrosis factor (TNF)-alpha and the joint tissue levels of macrophage inflammatory protein (MIP)-1alpha and MIP-2 were also significantly reduced by GSK-3beta inhibition. These data demonstrate that GSK-3beta inhibition exerts an anti-inflammatory effect during chronic inflammation and is able to ameliorate the tissue damage associated with CIA.
