PG - 1103-1109 LID - 10.19852/j.cnki.jtcm.2023.06.001 [doi] AB - OBJECTIVE: To observe the effect of electroacupuncture (EA) stimulating Zusanli (ST36), Sanyinjiao (SP6) on inhibition of osteoclastogenesis and the role of the adenosine A2A receptor (A2AR) and the p38alpha Mitogen-Activated Protein Kinase (MAPK) signaling pathway in mediating this effect. METHODS: Mice with collagen induced arthritis (CIA) received different treatments. Immunohistochemistry and western blotting were used to determine the levels of multiple signaling molecules in these joints [receptor activator of nuclear transcription factor-kappaB (NF-kappaB) ligand (RANKL), receptor activator of NF-kappaB (RANK), tumor necrosis factor receptor associated factor 6 (TRAF6), p38alpha, NF-kappaB, and nuclear factor of activated T cells C1 (NFATc1)]. Osteoclasts were identified using tartrate-resistant acid phosphatase (TRAP) staining. RESULTS: The immunohistochemistry results indicated upregulation of p38alpha, NF-kappaB, and NFATc1 in the CIA-control and CIA-EA-SCH58261 groups, but reduced levels in the CIA-EA group. Western blotting indicated upregulation of RANKL, RANK, TRAF6, p38alpha, NF-kappaB, and NFATc1 in the CIA-control and CIA-EA-SCH58261 groups, but reduced expression in the CIA-EA group. Osteoclasts were more abundant in the CIA-control and CIA-EA-SCH58261 groups than in the CIA-EA group. CONCLUSIONS: EA treatment enhanced the A2AR activity and inhibited osteoclast formation by inhibition of RANKL, RANK, TRAF6, p38alpha, NF-kappaB, and NFATc1. SCH58261 reversed the effect of EA. These results suggest that EA regulated p38alpha-MAPK signaling by increasing A2AR activity, which inhibited osteoclastogenesis.
