Coenzyme Q10 (CoQ10) is a lipid-soluble antioxidant synthesized in human body. This enzyme promotes immune system function and can be used as a dietary supplement. Rheumatoid arthritis (RA) is an autoimmune disease leading to chronic joint inflammation. RA results in severe destruction of cartilage and disability. This study aimed to investigate the effect(More)
Osteoarthritis (OA) is a degenerative joint disease characterized by a progressive loss of cartilage. And, increased oxidative stress plays a relevant role in the pathogenesis of OA. Ursodeoxycholic acid (UDCA) is a used drug for liver diseases known for its free radical-scavenging property. The objectives of this study were to investigate the in vivo(More)
OBJECTIVE Rebamipide, a gastroprotective agent, has the ability to scavenge reactive oxygen radicals. Increased oxidative stress is implicated in the pathogenesis of rheumatoid arthritis (RA). We undertook this study to investigate the impact of rebamipide on the development of arthritis and the pathophysiologic mechanisms by which rebamipide attenuates(More)
Increases in oxidative stress are thought to be associated with the development of osteoarthritis (OA). Eupatilin, one of the major compounds present in artemisia species, was shown to have both anti-oxidative and anti-inflammatory properties. Here, we investigated the in vivo effects of eupatilin on pain severity and cartilage degradation in an(More)
Osteoarthritis (OA) is a degenerative joint disease characterized by the progressive loss of articular cartilage and chronic pain. Although cyclooxygenase-2 (COX-2) inhibitors such as celecoxib are recommended to patients at high risk of gastrointestinal (GI) adverse events, COX-2 inhibitors do not completely prevent GI adverse events. Rebamipide, a(More)
Metformin (Met) and coenzyme Q10 (CoQ10) are reported to have therapeutic functions in several inflammatory diseases. These drugs have shown anti-inflammatory effects and have been utilized in mouse models of rheumatoid arthritis (RA). However, there is no evidence of the additive effect of Met and CoQ10 in RA. Although Met and CoQ10 may be involved in the(More)
Osteoarthritis (OA) is a degenerative and inflammatory disorder on particular joint inducing annihilation of articular cartilage. This study is aimed to investigate the therapeutic effect of extract of chicken combs (CCE) on pain severity and cartilage degeneration in an experimental model of rat OA. OA was induced in rats by intra-articular injection of(More)
RESULTS The oral administration of rebamipide decreased plaque formation in atherosclerotic lesions as well as the markers of metabolic disorder in ApoE-deficient mice with atherosclerosis. Pro-inflammatory cytokines were also suppressed by rebamapide. In addition, the population of Th17 was decreased, whereas Treg was increased in the spleen of(More)
Regulator of calcineurin 3 (RCAN3), an endogenous regulator of the calcineurin-nuclear factor of activated T cells (NFAT) signaling pathway, inhibits the phosphatase activity of calcineurin, the nuclear translocation of NFAT, and the NFAT downstream pathway. To investigate the effects of RCAN3 on T-cell regulatory function and the development and(More)
