Moxibustion of Zusanli (ST36) and Shenshu (BL23) Alleviates Cartilage Degradation through RANKL/OPG Signaling in a Rabbit Model of Rheumatoid Arthritis.
GRACE risk score was significantly higher in RA patients vs. those without RA (140.45 vs. 125.50, p = 0.030) and correlated with exRANKL, RANKL:OPG, hs-CRP, and hs-TnI.
In conclusion, paroxetine and rivastigmine possess antirheumatoid effects in CFA-induced RA which is mediated through antioxidant, anti-inflammatory, antiapoptotic and modulation of RANKL/OPG expression levels.
Effect of iguratimod and methotrexate on RANKL and OPG expression in serum and IL-1β-induced fibroblast-like synoviocytes from patients with rheumatoid arthritis.
According to the observation, there are no significant differences between the RA and control groups with respect to genotype and allele frequencies of OPG gene 245T/G (χ(2)=0.734, 0.518, p>0.05).
We isolated human fibroblasts from RA, pyrophosphate arthropathy (PPA) and osteoarthritis (OA) patients and analyzed their RANKL/OPG expression profile and the capacity of their secreted factors to induce osteoclastogenesis.
The high RANKL:OPG ratio, together with close fibroblast-to-monocyte contacts in pannus tissue, probably favor local generation of bone resorbing osteoclasts at the site of erosion in rheumatoid arthritis.
OPG mRNA was observed in the blood of all (17/17) early RA patients, but could not be detected in chronic RA patients (0/14) or in patients with OA (0/8).
